- on an Alpha running GNU/Linux, as predicted):
- * equiv.c (ffeequiv_layout_local_): Don't bother
- coping with pre-padding of entire area while building
- it; do that instead after the building is done, and

- the case of alignment stringency being increased without

- and even more elegantly than those.
-
- * target.c (ffetarget_align): Make sure alignments
- are nonzero, just in case.

- of g77.c, making filtering of command line smarter
- so mixed Fortran and C (etc.) can be compiled, verbose
- version info can be obtained, etc.

- f77.uninstall, $(G77STAGESTUFF), f77.stage1, f77.stage2,
- f77.stage3, f77.stage4, f77.distdir): Don't do anything
- unless user specified "f77" or "F77" in $LANGUAGES either
- during configuration or explicitly. For convenience of
- various tests and to work around lack of the assignment

- to communicate whether this is the case.

- via $(prefix) and $(local_prefix). (g++ overwrites
- /usr/bin/c++, but then it's often the only C++ compiler
- on the system; f77 often exists on systems that are
- installing g77.)
- (f77.realclean): Remove obsolete target.
- (g77.c, g77$(exeext)): Minor changes to look more like g++'s
- stuff.

- (f77.install-man): No longer install f77.1.
- (f77.uninstall): No longer uninstall f77, f77.1, etc.

- LANGUAGES=$(BOOT_LANGUAGES) when making the stage1 target.)
- * Makefile.in: Update vis-a-vis gcc/cp/Makefile.in.
- (none): Remove.
- (g77-only): Relocate.
- (all.indirect, f771, *.o): Now assumes current directory
- is this dir (gcc/f), not the parent directory.

- * config-lang.in: Delete commented-out code.
- Fix stagestuff definition. Add more stuff to

- to happen (what does that really do, anyway?!).
- * g77spec.c: Rename libf2c to libg2c.
-
- * com.h: Remove all of the gcc back-end decls,
- since egcs should have all of them correct.
-
- * com.c: Include "proj.h" before anything else,
- as that's how things are supposed to work.
- * ste.c: Ditto.
-
- * bad.c: Include "flags.j" here, since some diagnostics
- check flag_pedantic_errors.
-
- * Makefile.in (f/*.o): Rebuild dependencies via

-
- * com.c (ffecom_finish_symbol_transform_): Don't transform
- statement (nested) functions, to avoid gcc compiling them
- and thus producing linker errors if they refer to undefined
- external functions. But warn if they're unused and -Wunused.
- * bad.def (FFEBAD_SFUNC_UNUSED): New diagnostic.
-
-Wed May 20 12:12:55 1998 Craig Burley <burley@gnu.org>

- No need to test codegen_imp -- there's only one valid here.
-
- * intrin.def (FFEINTRIN_impALARM): Specify `Status' argument

-
-Fri Aug 8 05:40:23 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- Substantial changes to accommodate distinctions among
- run-time routines that support intrinsics, and between

- * com-rt.def: Specify new return type REAL_F2C_ instead
- of many DOUBLE_, COMPLEX_F2C_ instead of COMPLEX_, and
- so on.
- Clear up the *BES* routines "once and for all".
- * com.c: New return types.
- (ffecom_convert_narrow_, ffecom_convert_widen_):
- New functions that are "safe" variants of convert(),
- to catch errors that ffecom_expr_intrinsic_() now
- no longer catches.
- (ffecom_arglist_expr_): Ensure arguments are not
- converted to narrower types.
- (ffecom_call_): Ensure return value is not converted
- to a wider type.
- (ffecom_char_args_): Use new ffeintrin_gfrt_direct()
- routine.
- (ffecom_expr_intrinsic_): Simplify how run-time
- routine is selected (via `gfrt' only now; lose the
- redundant `ix' variable).
- Eliminate the `library' label; any code that doesn't
- return directly just `break's out now with `gfrt'
- set appropriately.
- Set `gfrt' to default choice initially, either a
- fast direct form or, if not available, a slower
- indirect-callable form.
- (ffecom_make_gfrt_): No longer need to do special
- check for complex; it's built into the new return-type
- regime.
- (ffecom_ptr_to_expr): Use new ffeintrin_gfrt_indirect()
- routine.
- * intrin.c, intrin.h: `gfrt' field replaced with three fields,
- so it is easier to provide faster direct-callable and
- GNU-convention indirect-callable routines in the future.
- DEFIMP macro adjusted accordingly, along with all its uses.
- (ffeintrin_gfrt_direct): New function.
- (ffeintrin_gfrt_indirect): Ditto.
- (ffeintrin_is_actualarg): If `-fno-f2c' is in effect,
- require a GNU-callable version of intrinsic instead of
- an f2c-callable version, so indirect calling is still checked.
- * intrin.def: Replace one GFRT field with the three new fields,
- as appropriate for each DEFIMP intrinsic.
-
- * com.c (ffecom_stabilize_aggregate_,
- ffecom_convert_to_complex_): Make these `static'.
-
-Thu Aug 7 11:24:34 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- Provide means for front end to determine actual

- (ffecom_gfrt_kind_type_): Replaced with new function.
- All callers updated.
- (ffecom_make_gfrt_): No longer need do anything
- with kind type.
-
- * intrin.c (ffeintrin_basictype, ffeintrin_kindtype):
- Now returns correct type info for specific intrinsic
- (based on type of run-time-library implementation).
-
-Wed Aug 6 23:08:46 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * global.c (ffeglobal_ref_progunit_): Don't reset
- number of arguments just due to new type info,
- so useful warnings can be issued.
-
-1997-08-06 Dave Love <d.love@dl.ac.uk>
-
- * intrin.def: Fix IDATE_vxt argument order.
- * intdoc.h: Likewise.
-
-Thu Jul 31 22:22:03 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * global.c (ffeglobal_proc_ref_arg): If REF/DESCR
- disagreement, DESCR is CHARACTER, and types disagree,
- pretend the argsummary agrees so the message ends up
- being about type disagreement.
- (ffeglobal_proc_def_arg): Ditto.
-
- * expr.c (ffeexpr_token_first_rhs_3_): Set info for LABTOK
- to NONE of everything, to avoid misdiagnosing filewide
- usage of alternate returns.
-
-Sun Jul 20 23:07:47 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_sym_transform_): If type gets set

- (ffecom_member_phase2_): If type gets set to error_mark_node,
- just return.
- (ffecom_check_size_overflow_): Add `dummy' argument to
- flag that type is for a dummy, update all callers.
-
-Sun Jul 13 17:40:53 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- Fix 970712-1.f:
- * where.c (ffewhere_set_from_track): If start point
- is too large, just use initial start point. 0.6 should
- fix all this properly.
-
- Fix 970712-2.f:
- * com.c (ffecom_sym_transform_): Preserve error_mark_node for type.
- (ffecom_type_localvar_): Ditto.
- (ffecom_sym_transform_): If type is error_mark_node,
- don't error-check decl size, because back end responds by
- setting that to an integer 0 instead of error_mark_node.
- (ffecom_transform_common_): Same as earlier fix to _transform_
- in that size is checked by dividing BITS_PER_UNIT instead of
- multiplying.
- (ffecom_transform_equiv_): Ditto.
-
- Fix 970712-3.f:
- * stb.c (ffestb_R10014_): Fix flaky fall-through in error

-
-Thu Jun 26 04:19:40 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- Fix 970302-3.f:
- * com.c (ffecom_sym_transform_): For sanity-check compare
- of gbe size of local variable to g77 expectation,
- use varasm.c/assemble_variable technique of dividing
- BITS_PER_UNIT out of gbe info instead of multiplying
- g77 info up, to avoid crash when size in bytes is very
- large, and overflows an `int' or similar when multiplied.
-
- Fix 970626-2.f:
- * com.c (ffecom_finish_symbol_transform_): Don't bother
- transforming a dummy argument, to avoid a crash.
- * ste.c (ffeste_R1227): Don't return a value if the
- result decl, or its type, is error_mark_node.
-
- Fix 970626-4.f:
- * lex.c (ffelex_splice_tokens): `-fdollar-ok' is
- irrelevant to whether a DOLLAR token should be made
- from an initial character of `$'.
-
- Fix 970626-6.f:
- * stb.c (ffestb_do3_): DO iteration variable is an
- lhs, not rhs, expression.
-
- Fix 970626-7.f and 970626-8.f:
- * expr.c (ffeexpr_cb_comma_i_1_): Set IMPDO expression
- to have clean info, because undefined rank, for example,
- caused crash on mangled source on UltraSPARC but not
- on Alpha for a series of weird reasons.
- (ffeexpr_cb_close_paren_): If not CLOSE_PAREN, push
- opANY expression onto stack instead of attempting
- to mimic what program might have wanted.
- (ffeexpr_cb_close_paren_): Don't wrap opPAREN around
- opIMPDO, just warn that it's gratuitous.
- * bad.def (FFEBAD_IMPDO_PAREN): New warning.
-
- Fix 970626-9.f:
- * expr.c (ffeexpr_declare_parenthesized_): Must shut down
- parsing in kindANY case, otherwise the parsing engine might
- decide there's an ambiguity.
- (ffeexpr_token_name_rhs_): Eliminate parentypeSUBROUTINE_
- case, so we crash right away if it comes through.
- * st.c, st.h, sta.c, sta.h (ffest_shutdown, ffesta_shutdown):
- New functions.
-
-Tue Jun 24 19:47:29 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_check_size_overflow_): New function

- of argno to #args.
- (ffeglobal_proc_ref_arg): Ditto.
-
- * lang-options.h, top.c: Rename `-fdebug' to `-fxyzzy',

- Put all filewides together.
- * com.c (ffecom_sym_transform_): Don't substitute
- known global tree for global entities when `-fno-globals'.
- * global.c (ffeglobal_new_progunit_): Don't produce
- fatal diagnostics about globals when `-fno-globals'.

- (ffeglobal_ref_progunit_): Ditto.

- (ffeintrin_fulfill_specific), (ffeintrin_is_intrinsic),
- intrin.def: The documented name is now either in the
- generic info or, if no generic, in the specific info.
- For a generic, the specific info contains merely the
- distinguishing form (usually "function" or "subroutine"),
- used for diagnostics about ambiguous references and
- in the documentation.
-
- * intrin.def: Clean up formatting of DEFNAME block.
- Convert many libU77 intrinsics into generics that
- support both subroutine and function forms.

-
- Fix bugs preventing CTIME(I*4) from working correctly:

- * global.h: Ditto.
- * expr.c (ffeexpr_fulfill_call_): A SYMTER with kindNONE
- also is a procedure (either function or subroutine).
-
-Mon May 26 20:25:31 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * bad.def: Have several lexer diagnostics refer to
- documentation for people who need more info on what Fortran

- specific to .NOT. now mention only one operand instead
- of two.

-
-Sun May 18 21:14:59 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com-rt.def: Changed all external names of the
- form `"\([a-z0-9]*\)_' to `"G77_\1_0"' so as to

- using new ffesymbol_reference function instead of
- ffesymbol_globalize.
- * global.c (ffeglobal_type_string_): New array for
- new diagnostics.
- * global.h, global.c:
- Replace ->init mechanism with ->tick mechanism.
- Move other common-related members into a substructure of
- a union, so the proc substructure can be introduced

- Call ffesymbol_reference, not ffesymbol_globalize.
- * symbol.c (ffesymbol_globalize): Removed...
- (ffesymbol_reference): ...to this new function,

- globalizes globals, and calls on the ffeglobal module
- to check globals filewide.
-
- * global.h, global.c: Rename some macros and functions
- to more clearly distinguish common from other globals.
- All callers changed.
-
- * com.c (ffecom_sym_transform_): Trees describing

- context can't be an intrinsic invocation either.
-
-Fri Mar 28 10:43:28 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * expr.c (ffeexpr_token_arguments_): Make sure top of
- exprstack is operand before dereferencing operand field.
-

- happen later.
-
- * stb.c (ffestb_R10014_): If NAMES isn't recognized (or
- the recognized part is followed in the token by a
- non-digit), don't try and collect digits, as there
- might be more than FFEWHERE_indexMAX letters to skip
- past to do so -- and the code is diagnosed anyway.
-
-Thu Mar 27 00:02:48 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_sym_transform_): Force local

- column counter itself, as well as the card image.
-
- * where.c (ffewhere_line_new): Cast ffelex_line_length()
- to (size_t) so 255 doesn't overflow to 0!
-
- * stc.c (ffestc_labeldef_notloop_begin_): Don't gratuitously
- terminate loop before processing statement, so block
- doesn't disappear out from under EXIT/CYCLE processing.
- (ffestc_labeldef_notloop_): Has old code from above
- function, instead of just calling it.
-
- * expr.c (ffeexpr_cb_comma_i_4_): Don't skip over
- arbitrary token (such as EOS).
-
- * com.c (ffecom_init_zero_): Handle RECORD_TYPE and
- UNION_TYPE so -fno-zeros works with -femulated-complex.
-
-1997-03-12 Dave Love <d.love@dl.ac.uk>
-
- * intrin.def: New intrinsics INT2, INT8, CPU_TIME. Fix AND, OR,

- implementation changed/fixed.]
-
-Wed Mar 12 10:40:08 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * Make-lang.in ($(srcdir)/f/intdoc.texi): Simplify rules

- f/intdoc after running it if it is built.
-
-Tue Mar 11 23:42:00 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * intrin.def (FFEINTRIN_impAND, FFEINTRIN_impOR,
- FFEINTRIN_impXOR): Use the IAND, IOR, and IEOR implementations
- of these, instead of crashing in ffecom_expr_intrinsic_
- or adding case labels there.
-
-Mon Mar 10 22:51:23 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * intdoc.c: Fix so any C compiler can compile this.
-
-Fri Feb 28 13:16:50 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * Version 0.5.20 released.
-
-Fri Feb 28 01:45:25 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * Make-lang.in (RUNTIMESTAGESTUFF, LIBU77STAGESTUFF):
- Move some files incorrectly in the former to the latter,
- and add another file or two to the latter.
-
- New meanings for (KIND=n), and new denotations in the
- little language describing intrinsics:
- * com.c (ffecom_init_0): Assign new meanings.
- * intdoc.c: Document new meanings.
- Support the new denotations.
- * intrin.c: Employ new meanings, mapping them to internal
- values (which are the same as they ever were for now).
- Support the new denotations.
- * intrin.def: Switch DEFIMP table to the new denotations.
-
- * intrin.c (ffeintrin_check_): Fix bug that was leaving
- LOC() and %LOC() returning INTEGER*4 on systems where

-
- * type.c: Canonicalize function definitions, for etags
- and such.
-
-Wed Feb 26 20:43:03 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_init_0): Choose INTEGER(KIND=n) types,
- where n is 2, 3, and 4, according to the new docs
- instead of according to the old C correspondences
- (which seem less useful at this point).
-
- * equiv.c (ffeequiv_destroy_): New function.
- (ffeequiv_layout_local_): Use this new function
- whenever the laying out of a local equivalence chain
- is aborted for any reason.
- Otherwise ensure that symbols no longer reference
- the stale ffeequiv entries that result when they
- are killed off in this procedure.
- Also, the rooted symbol is one that has storage,
- it really is irrelevant whether it has an equiv entry
- at this point (though the code to remove the equiv
- entry was put in at the end, just in case).
- (ffeequiv_kill): When doing internal checks, make
- sure the victim isn't named by any symbols it points
- to. Not as complete a check as looking through the
- entire symbol table (which does matter, since some
- code in equiv.c used to remove symbols from the lists
- for an ffeequiv victim but not remove that victim as the
- symbol's equiv info), but this check did find some
- real bugs in the code (that were fixed).
-
-Mon Feb 24 16:42:13 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_expr_intrinsic_): Fix a couple of
- warnings about uninitialized variables.
- * intrin.c (ffeintrin_check_): Ditto, but there were
- a couple of _real_ uninitialized-variable _bugs_ here!
- (ffeintrin_fulfill_specific): Ditto, no real bug here.
-
-Sun Feb 23 15:01:20 1997 Craig Burley <burley@gnu.ai.mit.edu>
-

- (FFEBAD_INTRINSIC_*, FFEBAD_NEED_INTRINSIC): Clean these
- up so they're friendlier.
- (FFEBAD_INTRINSIC_CMPAMBIG): New.
- * intrin.c (ffeintrin_fulfill_generic,
- ffeintrin_fulfill_specific, ffeintrin_is_intrinsic):
- Always choose
- generic or specific name text (which is for doc purposes
- anyway) over implementation name text (which is for
- internal use).
- * intrin.def: Use more descriptive name texts for generics
- and specifics in cases where the names themselves are not
- enough (e.g. IDATE, which has two forms).
-
- Fix some intrinsic mappings:
- * intrin.def (FFEINTRIN_specIDINT, FFEINTRIN_specAND,
- FFEINTRIN_specDFLOAT, FFEINTRIN_specDREAL, FFEINTRIN_specOR,
- FFEINTRIN_specXOR): Now have their own implementations,
- instead of borrowing from others.
- (FFEINTRIN_specAJMAX0, FFEINTRIN_specAJMIN0, FFEINTRIN_specBJTEST,
- FFEINTRIN_specDFLOTJ, FFEINTRIN_specFLOATJ, FFEINTRIN_specJIABS,
- FFEINTRIN_specJIAND, FFEINTRIN_specJIBCLR, FFEINTRIN_specJIBITS,
- FFEINTRIN_specJIBSET, FFEINTRIN_specJIDIM, FFEINTRIN_specJIDINT,
- FFEINTRIN_specJIDNNT, FFEINTRIN_specJIEOR, FFEINTRIN_specJIFIX,
- FFEINTRIN_specJINT, FFEINTRIN_specJIOR, FFEINTRIN_specJISHFT,
- FFEINTRIN_specJISHFTC, FFEINTRIN_specJISIN, FFEINTRIN_specJMAX0,
- FFEINTRIN_specJMAX1, FFEINTRIN_specJMIN0, FFEINTRIN_specJMIN1,
- FFEINTRIN_specJMOD, FFEINTRIN_specJNINT, FFEINTRIN_specJNOT,):
- Turn these implementations off, since it's not clear
- just what types they expect in the context of portable Fortran.
- (DFLOAT): Now in FVZ family, since f2c supports them
-
- Support intrinsic inquiry functions (BIT_SIZE, LEN):
- * intrin.c: Allow `i' in <arg_extra>.
- * intrin.def (FFEINTRIN_impBIT_SIZE, FFEINTRIN_impLEN):
- Mark args with `i'.
-
-Sat Feb 22 13:34:09 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- Only warn, don't error, for reference to unimplemented
- intrinsic:
- * bad.def (FFEBAD_INTRINSIC_UNIMPLW): Warning version
- of _UNIMPL.
- * intrin.c (ffeintrin_is_intrinsic): Use new warning
- version of _UNIMPL (FFEBAD_INTRINSIC_UNIMPLW).
-
- Complain about REAL(Z) and AIMAG(Z) (Z is DOUBLE COMPLEX):
- * bad.def (FFEBAD_INTRINSIC_CMPAMBIG): New diagnostic.
- * expr.c: Needed #include "intrin.h" anyway.
- (ffeexpr_token_intrincheck_): New function handles delayed
- diagnostic for "REAL(REAL(expr)" if next token isn't ")".
- (ffeexpr_token_arguments_): Do most of the actual checking here.
- * intrin.h, intrin.c (ffeintrin_fulfill_specific): New
- argument, check_intrin, to tell caller that intrin is REAL(Z)
- or AIMAG(Z). All callers updated, mostly to pass NULL in
- for this.
- (ffeintrin_check_): Also has new arg check_intrin for same
- purpose. All callers updated the same way.
- * intrin.def (FFEINTRIN_impAIMAG): Change return type
- from "R0" to "RC", to accommodate f2c (and perhaps other
- non-F90 F77 compilers).
- * top.h, top.c: New option -fugly-complex.
-
- New GNU intrinsics REALPART, IMAGPART, and COMPLEX:
- * com.c (ffecom_expr_intrinsic_): Implement impCOMPLEX
- and impREALPART here. (specIMAGPART => specAIMAG.)
- * intrin.def: Add the intrinsics here.
-
- Rename implementations of VXTIDATE and VXTTIME to IDATEVXT
- and TIMEVXT, so they sort more consistently:
- * com.c (ffecom_expr_intrinsic_):
- * intrin.def:
-
- Delete intrinsic group `dcp', add `gnu', etc.:
- * intrin.c (ffeintrin_state_family): FFEINTRIN_familyGNU
- replaces FFEINTRIN_familyDCP, and gets state from `gnu'
- group.
- Get rid of FFEINTRIN_familyF2Z, nobody needs it.
- Move FFEINTRIN_specDCMPLX from DCP family to FVZ family,
- as f2c has it.
- Move FFEINTRIN_specDFLOAT from F2C family to FVZ family.
- (FFEINTRIN_specZABS, FFEINTRIN_specZCOS, FFEINTRIN_specZEXP,
- FFEINTRIN_specZLOG, FFEINTRIN_specZSIN, FFEINTRIN_specZSQRT):
- Move these from F2Z family to F2C family.
- * intrin.h (FFEINTRIN_familyF2Z, FFEINTRIN_familyDCP): Remove.
- (FFEINTRIN_familyGNU): Add.
- * top.h, top.c: Replace `dcp' with `gnu'.
-
- * com.c (ffecom_expr_intrinsic_): Clean up by collecting
- simple conversions into one nice, conceptual place.
- Fix up some intrinsic subroutines (MVBITS, KILL, UMASK) to
- properly push and pop call temps, to avoid wasting temp
- registers.
-
- * g77.c (doit): Toon says variables should be defined
- before being referenced. Spoilsport.
-
- * intrin.c (ffeintrin_check_): Now Dave's worried about
- warnings about uninitialized variables. Okay, so for
- basic return values 'g' and 's', they _were_
- uninitialized -- is determinism really _that_ useful?
-
- * intrin.def (FFEINTRIN_impFGETC): Fix STATUS argument
- so that it is INTENT(OUT) instead of INTENT(IN).
-
-1997-02-21 Dave Love <d.love@dl.ac.uk>
-
- * intrin.def, com.c: Support Sun-type `short' and `long'
- intrinsics. Perhaps should also do Microcruft-style `int2'.
-
-Thu Feb 20 15:16:53 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_expr_intrinsic_): Clean up indentation.
- Support SECONDSUBR intrinsic implementation.
- Rename SECOND to SECONDFUNC for direct support via library.
-
- * g77.c: Fix to return proper status value to shell,
- by obtaining it from processes it spawns.
-
- * intdoc.c: Fix minor typo.
-
- * intrin.def: Turn SECOND into generic that maps into
- function and subroutine forms.
-
- * intrin.def: Make FLOAT and SNGL into specific intrinsics.
-
- * intrin.def, intrin.h: Change the way DEFGEN and DEFSPEC
- macros work, to save on verbage.
-
-Mon Feb 17 02:08:04 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- New subsystem to automatically generate documentation
- on intrinsics:
- * Make-lang.in ($(srcdir)/f/g77.info,
- $(srcdir)/f/g77.dvi): Move g77 doc rules around.
- Add to g77 doc rules the new subsystem.
- (f77.mostlyclean, f77.maintainer-clean): Also clean up
- after new doc subsystem.
- * intdoc.c, intdoc.h: New doc subsystem code.
- * intrin.h [FFEINTRIN_DOC]: When 1, don't pull in
- stuff not needed by doc subsystem.
-
- Improve on intrinsics mechanism to both be more
- self-documenting and to catch more user errors:
- * intrin.c (ffeintrin_check_): Recognize new arg-len
- and arg-rank information, and check it.
- Move goto and signal indicators to the basic type.
- Permit reference to arbitrary argument number, not
- just first argument (for BESJN and BESYN).
- (ffeintrin_init_0): Check and accept new notations.
- * intrin.c, intrin.def: Value in COL now identifies
- arguments starting with number 0 being the first.
-
- Some minor intrinsics cleanups (resulting from doc work):
- * com.c (ffecom_expr_intrinsic_): Implement FLUSH
- directly once again, handle its optional argument,
- so it need not be a generic (awkward to handle in docs).
- * intrin.def (BESJ0, BESJ1, BESJN, BESY0, BESY1, BESYN,
- CHDIR, CHMOD, CTIME, DBESJ0, DBESJ1, DBESJN, DBESY0,
- DBESY1, DBESYN, DDIM, ETIME, FGETC, FNUM, FPUTC, FSTAT,
- GERROR, GETCWD, GETGID, GETLOG, GETPID, GETUID, GMTIME,
- HOSTNM, IDATE, IERRNO, IIDINT, IRAND, ISATTY, ITIME, JIDINT,
- LNBLNK, LSTAT, LTIME, MCLOCK, PERROR, SRAND, SYMLNK, TTYNAM,
- UMASK): Change capitalization of initcaps (official) name
- to be consistent with Burley's somewhat arbitrary rules.
- (BESJN, BESYN): These have return arguments of same type
- as their _second_ argument.
- (FLUSH): Now a specific, not generic, intrinsic, with one
- optional argument.
- (FLUSH1): Eliminated.
- Add arg-len and arg-rank info to several intrinsics.
- (ITIME): Change argument type from REAL to INTEGER.
-
-Tue Feb 11 14:04:42 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * Make-lang.in (f771): Invocation of Makefile now done
- with $(srcdir)=gcc to go along with $(VPATH)=gcc.
- ($(srcdir)/f/runtime/configure,
- $(srcdir)/f/runtime/libU77/configure): Break these out
- so spurious triggers of this rule don't happen (as when
- configure.in is more recent than libU77/configure).
- (f77.rebuilt): Distinguish source versus build files,
- so this target can be invoked from build directory and
- still work.
- * Makefile.in: This now expects $(srcdir) to be the gcc
- source directory, not gcc/f, to agree with $(VPATH).
- Accordingly, $(INCLUDES) has been fixed, various cruft
- removed, the removal of f771 has been fixed to remove
- the _real_ f771 (not the one in gcc's parent directory),
- and so on.
-
- * lex.c: Part of ffelex_finish_statement_() now done
- by new function ffelex_prepare_eos_(), so that, in one
- popular case, the EOS can be prepared while the pointer
- is at the end of the non-continued line instead of the
- end of the line that marks no continuation. This improves
- the appearance of diagnostics substantially.
-
-Mon Feb 10 12:44:06 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * Make-lang.in: runtime Makefile's, and include/f2c.h,
- also depend on f/runtime/configure and f/runtime/libU77/configure.
-
- Fix various libU77 routines:
- * com-rt.def (FFECOM_gfrtCTIME, FFECOM_gfrtMCLOCK,
- FFECOM_gfrtTIME): These now use INTEGER*8 for time values,
- for compatibility with systems like Alpha.
- (FFECOM_gfrtSYSTEM_CLOCK, FFECOM_gfrtTTYNAM): Delete incorrect
- trailing underscore in routine names.
- * intrin.c, intrin.def: Support INTEGER*8 return values and
- arguments ('4'). Change FFEINTRIN_impCTIME, FFEINTRIN_impMCLOCK,
- and FFEINTRIN_impTIME accordingly.
- (ffeintrin_is_intrinsic): Don't give caller a clue about
- form of intrinsic -- shouldn't be needed at this point.
-
- Cope with generic intrinsics that are subroutines and functions:
- * com.c (ffecom_finish_symbol_transform_, ffecom_expr_transform_):
- Don't transform an intrinsic that is not known to be a subroutine
- or a function. (Maybe someday have to avoid transforming
- any intrinsic with an undecided or unknown implementation.)
- * expr.c (ffeexpr_declare_unadorned_,
- ffeexpr_declare_parenthesized_): Ok to invoke generic
- intrinsic that has at least one subroutine form as a
- subroutine.
- Ok to pass intrinsic as actual arg if it has a known specific
- intrinsic form that is valid as actual arg.
- (ffeexpr_declare_parenthesized_): An unknown kind of
- intrinsic has a paren_type chosen based on context.
- (ffeexpr_token_arguments_): Build funcref/subrref based
- on context, not on kind of procedure being called.
- * intrin.h, intrin.c (ffeintrin_is_intrinsic): Undo changes of
- Tue Feb 4 23:12:04 1997 by me, change all callers to leave
- intrinsics as FFEINFO_kindNONE at this point. (Some callers
- also had unused variables deleted as a result.)
-
- Enable all intrinsic groups (especially f90 and vxt):
- * target.h (FFETARGET_defaultSTATE_DCP, FFETARGET_defaultSTATE_F2C,
- FFETARGET_defaultSTATE_F90, FFETARGET_defaultSTATE_MIL,
- FFETARGET_defaultSTATE_UNIX, FFETARGET_defaultSTATE_VXT):
- Delete these macros, let top.c set them directly.
- * top.c (ffeintrinsic_state_dcp_, ffe_intrinsic_state_f2c_,
- ffe_intrinsic_state_f90_, ffe_intrinsic_state_mil_,
- ffe_intrinsic_state_unix_, ffe_intrinsic_state_vxt_):
- Enable all these directly.

- * g77.c: Incorporate recent changes to ../gcc.c.
- For version magic (e.g. `g77 -v'), instead of compiling
- /dev/null, write, compile, run, and then delete a small
- program that prints the version numbers of the three
- components of libf2c (libF77, libI77, and libU77),
- so we get this info with bug reports.
- Also, this change reduces the chances of accidentally
- linking to an old (complex-alias-problem) libf2c.
- Fix `-L' so the argument is expected in `-Larg'.
-
- * com.h (FFECOM_f2cLONGINT): For INTEGER*8 support in f2c.h,
- dynamically determine proper type here, instead of
- assuming `long long int' is correct.
-

- ($(srcdir)/f/runtime/configure: Use Makefile.in,
- so configuration doesn't have to have happened.
- (f77.mostlyclean, f77.clean, f77.distclean,
- f77.maintainer-clean): Some fixups here, but more work
- needed.
- (RUNTIMESTAGESTUFF): Add libU77's config.status.
- (LIBU77STAGESTUFF, f77.stage1, f77.stage2, f77.stage3,
- f77.stage4): New macro, appropriate uses added.
- * com-rt.def: Add libU77 procedures.
- * com.c (ffecom_f2c_ptr_to_integer_type_node,
- ffecom_f2c_ptr_to_real_type_node): New type nodes.
- (FFECOM_rttypeCHARACTER_): New type of run-time function.
- (ffecom_char_args_): Handle CHARACTER*n intrinsics

- (ffecom_expr_intrinsic_): New code to handle new
- intrinsics.
- In particular, change how FFEINTRIN_impFLUSH is handled.
- (ffecom_make_gfrt_): Handle new type of run-time function.
- (ffecom_init_0): Initialize new type nodes.
- * config-lang.in: New libU77 directory.

- potential generic for subroutine _and_ function
- specifics via two new arguments. All callers changed.
- Properly ignore deleted/disabled intrinsics in resolving
- generics.
- (ffeintrin_check_, ffeintrin_init_0): Handle CHARACTER intrinsics of (*)
- length.
- * intrin.def: Permission granted by FSF to place this in
- public domain, which will allow it to serve as source
- for both g77 program and its documentation.

- (FLUSH): Now a generic, not specific, intrinsic.
- (DEFIMP): Now support return modifier for CHARACTER intrinsics.
-
- * com-rt.def (FFECOM_gfrtDIM, FFECOM_gfrtERF,
- FFECOM_gfrtERFC, FFECOM_gfrtEXP, FFECOM_gfrtSIGN,
- FFECOM_gfrtSIN, FFECOM_gfrtSINH, FFECOM_gfrtTAN,

-
- * com.c (ffecom_init_0): Do internal checks only if
- -fset-g77-defaults not specified.
-
- Fix %LOC(), LOC() to return sufficiently wide type:
- * com.h, com.c (ffecom_pointer_kind_, ffecom_label_kind_,
- ffecom_pointer_kind(), ffecom_label_kind()): New globals
- and accessor macros hold kind for integer pointers on target
- machine.
- (ffecom_init_0): Determine narrowest INTEGER type that
- can hold a pointer (usually INTEGER*4 or INTEGER*8),
- store it in ffecom_pointer_kind_, etc.
- * expr.c (ffeexpr_cb_end_loc_): Use right type for %LOC().
- * intrin.c (ffeintrin_check_, ffeintrin_init_0): Support
- new 'p' kind for type of intrinsic.
- * intrin.def (FFEINTRIN_impLOC): Returns "Ip" instead of "I1",
- so LOC() type is correct for target machine.
-
- Support -fugly-assign:
- * lang-options.h, top.h, top.c (ffe_decode_option):
- Accept -fugly-assign and -fno-ugly-assign.

- contexts.
-
-Fri Jan 31 14:30:00 1997 Craig Burley <burley@gnu.ai.mit.edu>

- * stb.c (ffestb_R10012_, ffestb_R10014_, ffestb_V0201_):
- top.c, top.h:
-
-Fri Jan 31 02:13:54 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * top.c (ffe_decode_option): Warn if -fugly is specified,
- it'll go away soon.
-
- * symbol.h: No need to #include "bad.h".
-
- Reorganize features from -fvxt-not-f90 to -fvxt:
- * lang-options.h, top.h, top.c:
- Accept -fvxt and -fno-vxt, but not -fvxt-not-f90 or -ff90-not-vxt.
- Warn if the latter two are used.
- * expr.c (ffeexpr_nil_rhs_): Double-quote means octal constant.
- (ffeexpr_token_rhs_): Double-quote means octal constant.
- * target.h (FFETARGET_defaultIS_VXT_NOT_90): Delete macro
- definition, no longer needed.

-
- Fix up some more #error directives by quoting their text:
- * bld.c (ffebld_constant_is_zero):
- * target.h:
-
-Sat Jan 18 18:22:09 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * g77.c (lookup_option, main): Recognize `-Xlinker',
- `-Wl,', `-l', `-L', `--library-directory', `-o',
- `--output'.
- (lookup_option): Don't depend on SWITCH_TAKES_ARG
- being correct, it might or might not have `-x' in
- it depending on host.
- Return NULL argument if it would be an empty string.
- (main): If no input files (by gcc.c's definition)
- but `-o' or `--output' specified, produce diagnostic
- to avoid overwriting output via gcc.
- Recognize C++ `+e' options.
- Treat -L as another non-magical option (like -B).
- Don't append_arg `-x' twice.

-
- Enable inlining of previously-compiled program units:
- * com.c (ffecom_do_entry_, ffecom_start_progunit_):
- Register new public function in ffeglobal database.
- (ffecom_sym_transform_): Any GLOBAL or potentially GLOBAL
- symbol should be looked up in ffeglobal database and
- that tree node used, if found. That way, gcc knows
- the references are to those earlier definitions, so it
- can emit shorter branches/calls, inline, etc.
- (ffecom_transform_common_): Minor change for clarity.
- * expr.c (ffeexpr_sym-lhs_call_, ffeexpr_sym_lhs_extfunc_,
- ffeexpr_sym_rhs_actualarg_, ffeexpr_paren_rhs_let_,

-Thu Jan 9 14:20:00 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * ste.c (ffeste_R809): Produce a diagnostic for SELECT CASE
- on CHARACTER type, instead of crashing.
-
-Thu Jan 9 00:52:45 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * stc.c (ffestc_order_entry_, ffestc_order_format_,
- ffestc_R1226): Allow ENTRY and FORMAT before IMPLICIT
- NONE, by having them transition only to state 1 instead
- of state 2 (which is disallowed by IMPLICIT NONE).
-
-Mon Jan 6 22:44:53 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- Fix AXP bug found by Rick Niles (961201-1.f):
- * com.c (ffecom_init_0): Undo my 1996-05-14 change, as
- it is incorrect and prevented easily finding this bug.
- * target.h [__alpha__] (ffetargetReal1, ffetargetReal2):
- Use int instead of long.

-
- * Make-lang.in (g77, g77-cross): Depend on both g77.c and

- * stc.c (ffestc_R501_item, ffestc_R524_item,
- ffestc_R547_item_object): Pass new is_ugly_assumed flag.
- * stt.c, stt.h (ffestt_dimlist_as_expr,
- ffestt_dimlist_type): New is_ugly_assumed flag now
- controls whether "1" is treated as "*".
- Don't treat "2-1" or other collapsed constants as "*".
-
-Sat Jan 4 15:26:22 1997 Craig Burley <burley@gnu.ai.mit.edu>
-
- * stb.c (ffestb_R10012_): Don't confirm on FORMAT(A,)
- or even FORMAT(A,,B), as R1229 only warns about the
- former currently, and this seems reasonable.
-
- Improvements to diagnostics:
- * sta.c (ffesta_second_): Don't add any ffestb parsers
- unless they're specifically called for.
- Set up ffesta_tokens[0] before calling ffestc_exec_transition,
- else stale info might get used.
- (ffesta_save_): Do a better job picking which parser to run
- after running all parsers with no confirmed possibles.
- (FFESTA_maxPOSSIBLES_): Decrease from 100 now that so few
- possibles are ever on the list at a given time.
- (struct _ffesta_possible): Add named attribute.
- (ffesta_add_possible_exec_, ffesta_add_possible_nonexec_):
- Make these into macros that call a single function that now
- sets the named attribute.
- (ffesta_add_possible_unnamed_exec_,
- ffeseta_add_possible_unnamed_nonexec_): New macros.
- (ffesta_second_): Designate unnamed possibles as
- appropriate.
- * stb.c (ffestb_R1229, ffestb_R12291_): Use more general
- diagnostic, so things like "POINTER (FOO, BAR)" are
- diagnosed as unrecognized statements, not invalid statement
- functions.
- * stb.h, stb.c (ffestb_unimplemented): Remove function.
-
-1996-12-30 Dave Love <d.love@dl.ac.uk>
-
- * com.c: #include libU77/config.h
- (ffecom_f2c_ptr_to_integer_type_node,

- (ffecom_init_0): Use them.
- (ffecom_expr_intrinsic_): Many news cases for libU77 intrinsics.
-
- * com-rt.def: New definitions for libU77.
- * intrin.def: Likewise. Also correct ftell arg spec.
-
- * Makefile.in (f/runtime/libU77/config.h): New target for com.c
- dependency.
- * Make-lang.in (f771): Depend on f/runtime/Makefile for the above.
-
-Sat Dec 28 12:28:29 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * stt.c (ffestt_dimlist_type): Treat ([...,]1) in dimlist
- as ([...,]*) if -fugly-assumed, so assumed-size array
- detected early enough.
-
-Thu Dec 19 14:01:57 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * target.h (FFETARGET_REAL_VALUE_FROM_INT_): Conditionalize
- definition on BUILT_FOR_280, not BUILT_WITH_280, since
- the name of the macro was (properly) changed since 0.5.19.
-
- Fix warnings/errors resulting from ffetargetOffset becoming
- `long long int' instead of `unsigned long' as of 0.5.19,
- while ffebitCount remains `unsigned long':
- * bld.c (ffebld_constantarray_dump): Avoid warnings by
- using loop var of appropriate type, and using casts.
- * com.c (ffecom_expr_): Use right type for loop var.
- (ffecom_sym_transform_, ffecom_transform_equiv_):
- Cast to right type in assertions.
- * data.c (ffedata_gather_, ffedata_value_): Cast to right
- type in assertions and comparisons.
-
-Wed Dec 18 12:07:11 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- Patch from Alexandre Oliva <oliva@dcc.unicamp.br>:

-Fri Dec 6 12:23:55 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * g77.c: Default to assuming "f77" is in $LANGUAGES, since
- the LANGUAGE_F77 macro isn't defined by anyone anymore (but
- might as well leave the no-f77 code in just in case).
- * Make-lang.in (g77, g77-cross): Don't define LANGUAGE_F77
- anymore.
-
-1996-12-06 Dave Love <d.love@dl.ac.uk>

-
- * Make-lang.in (g77, g77-cross): No libs or lib dependencies
- in case where "f77" is not in $LANGUAGES.
-
- * lex.c (ffelex_image_char_, ffelex_file_fixed,
- ffelex_file_free): Fixes to properly handle lines with
- null character, and too-long lines as well.
-
- * lex.c: Call ffebad_start_msg_lex instead of
- ffebad_start_msg throughout.
-
-Sun Dec 1 21:19:55 1996 Craig Burley <burley@gnu.ai.mit.edu>

- ensure we get the same parent storage area.
- * data.c (ffedata_gather_, ffedata_value_): Subtract out
- aggregate offset.
-
-Wed Nov 27 13:55:57 1996 Craig Burley <burley@gnu.ai.mit.edu>

- * equiv.c (ffeequiv_layout_local_, ffeequiv_layout_cblock):
- More details for FFEBAD_EQUIV_MISMATCH.
-

- (ffeequiv_offset_): Add argument, change callers.
- Clean up the code, fix up the (probably unused) negative-value
- case for SYMTER.
- * com.c (ffecom_sym_transform_): For local EQUIVALENCE
- member, subtract out aggregate offset (which is <= 0).
-
-Thu Nov 21 12:44:56 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- Change type of ffetargetOffset from `unsigned long' to `long long':

- * storag.c (ffestorag_dump): Ditto.
- * symbol.c (ffesymbol_report): Ditto.
- * target.h (ffetargetOffset_f): Ditto and change type itself.
-
- Handle situation where list of languages does not include f77:
- * Make-lang.in: Define LANGUAGE_F77 to 1 only if `f77' is in
- the $LANGUAGES macro for the build.
- * g77.c: Compile to a (nearly) no-op program if LANGUAGE_F77

- ffestb_R91012_, ffestb_R91013_): Use new functions, and confirm
- except for the OPEN_PAREN case.
-
- Fixes to not confirm declarations with an open paren where
- an equal sign or other assignment-like token might be, so the
- corresponding assignments to same-named CHAR*(*) arrays work:
- (ffestb_decl_entsp_5_): Move assertion so we crash on that first,
- if it turns out to be wrong, before the less-debuggable crash
- on mistaken confirmation.
- (ffestb_decl_entsp_6_, ffestb_decl_entsp_7_, ffestb_decl_entsp_8_):
- Include OPEN_PAREN in list of assignment-only tokens.
-
- Fix more diagnosed-crash bugs:
- * stu.c (ffestu_sym_end_transition): ANY-ize an adjustable array
- with bad dimension expressions even if still stateUNCERTAIN.
- (ffestu_symter_end_transition_, ffestu_symter_exec_transition_):

-1996-11-14 Dave Love <d.love@dl.ac.uk>
-
- * Make-lang.in, config-lang.in: Remove the (broken) libU77 stuff,
- pending 0.5.20.

- for --verbose as well.
-
-Thu Nov 7 18:41:41 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * expr.c, lang-options.h, target.h, top.c, top.h: Split out
- remaining -fugly stuff into -fugly-logint and -fugly-comma,
- leaving -fugly as simply a `macro' that expands into other
- options, and eliminate defaults for some of the ugly stuff
- in target.h.
-
- * Make-lang.in (gcc-cross): Compile zzz.c, not version.o (!),
- in to get version info for this target.
-
- * config-lang.in: Test for GBE patch application based
- on whether 2.6.x or 2.7.x GBE is detected.
-
-Wed Nov 6 14:19:45 1996 Craig Burley <burley@gnu.ai.mit.edu>

- * intrin.c (ffeintrin_check_): Support `g' codes.
- * com-rt.def: Add ftell_() and fseek_() to database.
- * com.c (ffecom_expr_intrinsic_): Ditto. Also, let each
- subroutine intrinsic decide for itself what to do with
- tree_type, the default being NULL_TREE once again (so
- ffecom_call_ doesn't think it's supposed to cast the
- function call to the type in the fall-through case).
-
- * ste.c (ffeste_R909_finish): Don't special-case list-directed
- I/O, now that libf2c can return nonzero status codes.
- (ffeste_R910_finish): Ditto.

-
- * config-lang.in, Make-lang.in: Rename flag file
- build-u77 to build-libu77, for consistency with
- install-libf2c and such.
-
- * config-lang.in: Don't complain about failure to patch
- if pre-2.7.0 gcc is involved (since our patch for that
- doesn't add support for tooning).

-
- * bad.def (FFEBAD_TYPELESS_TOO_LARGE): Remove this

- ffeexpr_token_name_apos_name_, ffetarget_integerbinary,
- ffetarget_integerhex, ffetarget_integeroctal): Support
- new -fno-typeless-boz option with new functions, mods to
- existing octal-handling functions, new macros, new error
- messages, and so on.
-
- * com.c, lang-options.h, top.c, top.h (ffecom_notify_primary_entry):
- Print program unit name on stderr if -fno-silent (new option).
-
- * lang-options.h, top.c, top.h, stt.c (ffestt_dimlist_as_expr):
- Treat ([...,]1) in dimlist as ([...,]*) if -fugly-assumed
- (new option).
-
- * lang-options.h: Comment out options duplicated in gcc/toplev.c,
- because, somehow, having them commented in and building on my
- DEC Alpha results in a cc1 that always segfaults, and gdb that
- also segfaults whenever it debugs it up to init_lex() calling
- xmalloc() or so.
-
-Thu Oct 17 00:39:27 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * stb.c (ffestb_R10013_): Don't change meaning of .sign until
- after previous meaning/value used to set sign of value
- (960507-1.f).
-
-Sun Oct 13 22:15:23 1996 Craig Burley <burley@gnu.ai.mit.edu>
-

-Wed Oct 2 21:57:12 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_debug_kludge_): Set DECL_IN_SYSTEM_HEADER so
- -Wunused doesn't complain about these manufactured decls.
- (ffecom_expr_): Ditto, for original (non-ASSIGN'ed) variable.
- (ffecom_transform_equiv_): Clear DECL_IGNORED_P for aggregate
- area so it shows up as a debug-accessible symbol.
- (pushdecl): Default for "invented" identifiers (a g77-specific
- concept for now) is that they are artificial, in system header,
- ignored for debugging purposes, used, and (for types) suppressed.
- This ought to be overkill.
-
-Fri Sep 27 23:13:07 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * ste.c (ffeste_begin_iterdo_, ffeste_end_iterdo_): Support

-1996-09-24 Dave Love <d.love@dl.ac.uk>
-
- * Make-lang.in (include/f2c.h):
- Remove dependencies on xmake_file and tmake_file.
- They expand inconsistently in 2.8 c.f. 2.7; $(GCC_PARTS) depends on

-
- * config-lang.in: Add --enable-libu77 option handling.

- `stmp-hdrs' should have been `stmp-headers'.
-
-1996-08-20 Dave Love <d.love@dl.ac.uk>
-
- * Make-lang.in (f77-runtime):
- Depend on stmp-hdrs, not stmp-int-hdrs, since libF77
- needs float.h.

-Sat Jun 22 18:17:11 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_tree_divide_): Fix RECORD_TYPE case to

- (ffecom_convert_to_complex_): New function.
- (ffecom_make_complex_type_): New function.
- (ffecom_build_complex_constant_): New function.
- (ffecom_expr_): For opCONVERT of non-COMPLEX to COMPLEX,
- don't bother explicitly converting to the subtype first,
- because gcc does that anyway, and more code would have
- to be added to find the subtype for the emulated-complex
- case.
- (ffecom_f2c_make_type_): Use ffecom_make_complex_type_
- instead of make_node etc. to make a complex type.
- (ffecom_1, ffecom_2): Translate operations on COMPLEX operands
- to appropriate operations when emulating complex.

- for improved consistency.
- Use ffecom_make_complex_type_ instead of make_node etc.
- to make a complex type.
- Always calculate storage sizes from TYPE_SIZE, never TYPE_PRECISION.
- (convert): Use e, not expr, since we've copied into that anyway.
- For RECORD_TYPE cases, do emulated-complex conversions.
- (ffecom_f2c_set_lio_code_): Always calculate storage sizes
- from TYPE_SIZE, never TYPE_PRECISION.
- (ffecom_tree_divide_): Allow RECORD_TYPE to also be handled
- by run-time library.
- (ffecom_expr_intrinsic_): Handle possible RECORD_TYPE as argument
- to AIMAG intrinsic.
-
- * top.h, top.c, lang-options.h: Support new -f(no-)emulate-complex option.
-
- * com.c (ffecom_sym_transform_): Clarify and fix typos in comments.
-
-Mon May 20 02:06:27 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * target.h: Use new REAL_VALUE_UNTO_TARGET_* macros instead
- of REAL_VALUE_FROM_TARGET_DOUBLE and _SINGLE.
- Explicitly use long instead of HOST_WIDE_INT for emulation
- of ffetargetReal1 and ffetargetReal2.
-
-1996-05-20 Dave Love <d.love@dl.ac.uk>
-
- * config-lang.in:
- Test for patch being applied with flag_move_all_movables in toplev.c.
-
- * install.texi (Patching GNU Fortran):

- * Make-lang.in (F77_FLAGS_TO_PASS):
- Add X_CFLAGS (convenient for SunOS4 kluge, in
- particular).
- (f77.{,mostly,dist}clean): Reorder things, in particular not to delete
- Makefiles too early.
-
- * g77.c (DEFAULT_SWITCH_TAKES_ARG): Define a la gcc.c in the
- current GCC snapshot.
-
-Tue May 14 00:24:07 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- Changes for DEC Alpha AXP support:
- * com.c (ffecom_init_0): REAL_ARITHMETIC means internal
- REAL/DOUBLE PRECISION might well have a different size
- than the compiled type, so don't crash if this is the
- case.
- * target.h: Use `int' for ffetargetInteger1,
- ffetargetLogical1, and magical tests. Set _f format
- strings accordingly.
-
-Tue Apr 16 14:08:28 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * top.c (ffe_decode_option): -Wall no longer implies
- -Wsurprising.
-
-Sat Apr 13 14:50:06 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_char_args_): If item is error_mark_node,
- set *length that way, too.
-
- * com.c (ffecom_expr_power_integer_): If either operand
- is error_mark_node, return that.
-
- * com.c (ffecom_intrinsic_len_): If item is error_mark_node,

-
- * intrin.c (ffeintrin_check_), intrin.def (impSIGNAL):
- Allow procedure as second arg to SIGNAL intrinsic.
-
- * stu.c (ffestu_symter_end_transition_): New function.
- (ffestu_symter_exec_transition_): Return bool arg.
- Always transition symbol (don't inhibit when !whereNONE).
- (ffestu_sym_end_transition): If DUMMY/LOCAL arg has any
- opANY exprs in its dimlist, diagnose it so it doesn't
- make it through to later stages that try to deal with
- dimlist stuff.
- (ffestu_sym_exec_transition): If sym has any opANY exprs
- in its dimlist, diagnose it so it becomes opANY itself.
-
- * symbol.c (ffesymbol_error): If token arg is NULL,
- just ANY-ize the symbol -- don't produce diagnostic.
-
-Mon Apr 1 10:14:02 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * Version 0.5.18 released.
-
-Mon Mar 25 20:52:24 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_expr_power_integer_): Don't generate code
- that compares COMPLEX (or, as it happens, REAL) via "LT_EXPR",
- since the back end crashes on that. (This code would never
- be executed anyway, but the test that avoids it has now been
- translated to control whether the code gets generated at all.)
- Fixes 960323-3.f.
-
- * com.c (ffecom_type_localvar_): Handle variable-sized
- dimension bounds expressions here, so they get calculated
- and saved on procedure entry. Fixes 960323-4.f.
-
- * com.c (ffecom_notify_init_symbol): Symbol has no init
- info at all if only zeros have been used to initialize it.
- Fixes 960324-0.f.
-
- * expr.c, expr.h (ffeexpr_type_combine): Renamed from
- ffeexpr_type_combine_ and now a public procedure; last arg now
- a token, instead of an internal structure used to extract a token.
- Now allows the outputs to be aliased with the inputs.
- Now allows a NULL token to mean "don't report error".
- (ffeexpr_reduced_bool2_, ffeexpr_reduced_eqop2_,
- ffeexpr_reduced_math2_, ffeexpr_reduced_power_,
- ffeexpr_reduced_relop2_): Handle new calling sequence for
- ffeexpr_type_combine.
- * (ffeexpr_convert): Don't put an opCONVERT node
- in just because the size is unknown; all downstream code
- should be able to deal without it being there anyway, and
- getting rid of it allows new intrinsic code to more easily
- combine types and such without generating bad code.
- * info.c, info.h (ffeinfo_kindtype_max): Rewrite to do
- proper comparison of size of types, not just comparison
- of their internal kind numbers (so I2.eq.I1 doesn't promote
- I1 to I2, rather the other way around).
- * intrin.c (ffeintrin_check_): Combine types of arguments
- in COL a la expression handling, for greater flexibility
- and permissiveness (though, someday, -fpedantic should
- report use of this kind of thing).
- Make sure Hollerith/typeless where CHARACTER expected is
- rejected. This all fixes 960323-2.f.
-
- * ste.c (ffeste_begin_iterdo_): Fix some more type conversions
- so INTEGER*2-laden DO loops don't crash at compile time on
- certain machines. Believed to fix 960323-1.f.
-
- * stu.c (ffestu_sym_end_transition): Certainly reject
- whereDUMMY not in any dummy list, whether stateUNCERTAIN
- or stateUNDERSTOOD. Fixes 960323-0.f.
-
-Tue Mar 19 13:12:40 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * data.c (ffedata_value): Fix crash on opANY, and simplify
- the code at the same time.
-
- * Make-lang.in (f77-runtime): Also depends on lib[FI]77/Makefile...
- (include/f2c.h...): ...which in turn depend on */Makefile.in.
- (f77.rebuilt): Rebuild runtime stuff too.
-
- * intrin.c (ffeintrin_check_): Accommodate TYPELESS/HOLLERITH
- types, convert args as necessary, etc.
-
- * expr.c (ffeexpr_convert): Fix test for TYPELESS/HOLLERITH
- to obey the docs; crash if no source token when error.
- (ffeexpr_collapse_convert): Crash if no token when error.
-
-Mon Mar 18 15:51:30 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_init_zero_): Renamed from
- ffecom_init_local_zero_; now handles top-level
- (COMMON) initializations too.
-
- * bld.c (ffebld_constant_is_zero):
- * com.c (ffecom_symbol_transform_, ffecom_sym_transform_assign_,
- ffecom_transform_common_, ffecom_transform_equiv_):

- * storag.c:
- * storag.h:
- * symbol.c:
- * symbol.h:
- * target.c:
- * target.h:
- * top.c:
- * top.h: All of this is mostly housekeeping-type changes
- to support -f(no-)zeros, i.e. not always stuff zero
- values into the initializer fields of symbol/storage objects,
- but still track that they have been given initial values.
-
- * bad.def: Fix wording for DATA-related diagnostics.
-
- * com.c (ffecom_sym_transform_assign_): Don't check
- any EQUIVALENCE stuff for local ASSIGN, the check was
- bad (crashing), and it's not necessary, anyway.
-
- * com.c (ffecom_expr_intrinsic_): For MAX and MIN,
- ignore null arguments as far arg[123], and fix handling
- of ANY arguments. (New intrinsic support now allows
- spurious trailing null arguments.)
-
- * com.c (ffecom_init_0): Add HOLLERITH (unsigned)
- equivalents for INTEGER*2, *4, and *8, so shift intrinsics
- and other things that need unsigned versions of signed
- types work.
-
-Sat Mar 16 12:11:40 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * storag.c (ffestorag_exec_layout): Treat adjustable
- local array like dummy -- don't create storage object.
- * com.c (ffecom_sym_transform_): Allow for NULL storage
- object in LOCAL case (adjustable array).
-
-Fri Mar 15 13:09:41 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_sym_transform_): Allow local symbols
- with nonconstant sizes (adjustable local arrays).
- (ffecom_type_localvar_): Allow dimensions with nonconstant

- ffestu_sym_exec_transition): Ditto.
- * symbol.def: Update docs to reflect these changes.
-
- * com.c (ffecom_expr_): Reduce space/time needed for
- opACCTER case by handling it here instead of converting
- it to opARRTER earlier on.
- (ffecom_notify_init_storage): Don't convert ACCTER to ARRTER.
- (ffecom_notify_init_symbol): Ditto.
-
- * com.c (ffecom_init_0): Crash and burn if any of the types'
- sizes, according to the GBE, disagrees with the sizes of
- the FFE's internal implementation. This might catch
- Alpha/SGI bugs earlier.
-
-Fri Mar 15 01:09:41 1996 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com-rt.def, com.c, com.h: Changes for rewrite of intrinsic

- * intrin.c: Major rewrite of most portions.
- * intrin.def: Major rearchitecting of tables.
- * intrin.h (ffeintrin_basictype, ffeintrin_kindtype):
- Now (once again) take ffeintrinSpec as arg, not ffeintrinImp;
- for now, these return NONE, since they're not really needed
- and adding the necessary info to the tables is not trivial.
- (ffeintrin_codegen_imp): New function.
- * stc.c (ffestc_R1208_item): Change way ffeintrin funcs called,
- back to original per above; but comment out the code anyway.

-
- * Make-lang.in (stmp-int-hdrs): Use --no-validate when
- generating the f77.rebuilt files (BUGS, INSTALL, NEWS)

- the way they end up looking in the f77.rebuilt files.
-
- * bld.c (ffebld_constant_new_integer4_val): INTEGER*8
- support -- new function.
- (ffebld_constant_new_logical4_val): New function.
- * com.c (ffecom_f2c_longint_type_node): New type.

- the usual work.
- (ffecom_make_gfrt_): Handle new type.
- (ffecom_expr_power_integer_): Let caller do the work if in
- dummy-transforming case, since
- caller now knows about INTEGER*8 and such, by returning
- NULL_TREE.
- * expr.c (ffeexpr_reduced_power_): Complain about non-INTEGER
- raised to INTEGER4 (INTEGER*8) power.
-
- * target.c (ffetarget_power_integerdefault_integerdefault):

- * stp.h: Ditto.
- * str-1t.fin: Ditto.
- * str-2t.fin: Ditto.
-
- * expr.c (ffeexpr_finished_): For DO loops, allow
- any INTEGER type; convert LOGICAL (assuming -fugly)
- to corresponding INTEGER type instead of always default
- INTEGER; let later phases do conversion of DO start,
- end, incr vars for implied-DO; change checks for non-integral
- DO vars to be -Wsurprising warnings.
- * ste.c (ffeste_io_impdo_): Convert start, end, and incr
- to type of DO variable.
-
- * com.c (ffecom_init_0): Add new types for [IL][234],
- much of which was done by Scott Snyder <snyder@d0sgif.fnal.gov>.
- * target.c: Ditto.
- * target.h: Ditto.
-
-Wed Mar 6 14:08:45 1996 Craig Burley <burley@gnu.ai.mit.edu>

-
- * expr.c (ffeexpr_declare_unadorned_,
- ffeexpr_declare_parenthesized_): Break out handling of
- contextDATAIMPDO[INDEX,CTRL] so it's independent of symbol state.
- Don't exec-transition these here (let ffeexpr_sym_impdoitem_
- handle that when appropriate). Don't "declare" them twice.
-
-Tue Dec 5 06:48:26 1995 Craig Burley <burley@gnu.ai.mit.edu>
-
- * stc.c (ffestc_promote_sfdummy_): Allow whereNONE parent
- symbol, since it is not necessarily known whether it will
- become LOCAL or DUMMY.
-

-
- * lex.c (ffelex_display_token, ffelex_type_string_): Resurrect

- for "no checking" to improve compile times.
-
- * malloc.c (malloc_pool_kill): Fix bug that could prevent
- subpool from actually being killed (wasn't setting its use
- count to 1).
-
- * proj.h, *.c (dmpout): Replace all occurrences of `stdout'
- and some of `stderr' with `dmpout', so where to dump debugging
- output can be easily controlled during build; add default

-Sun Dec 3 00:56:29 1995 Craig Burley <burley@gnu.ai.mit.edu>
-
- * com.c (ffecom_return_expr): Eliminate attempt at warning
- about unset return values, since the back end does this better,
- with better wording, and is not triggered by clearly working
- (but spaghetti) code as easily as this test.
-
-Sat Dec 2 08:28:56 1995 Craig Burley <burley@gnu.ai.mit.edu>
-
- * target.c (ffetarget_power_*_integerdefault): Raising 0 to

- has any content, not just if it finishes a previous line
- or has a label.
- (ffelex_file_free): Clarify switch statement code.
-
-Sat Nov 18 19:37:22 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Version 0.5.17 released.
-
-Fri Nov 17 14:27:24 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Make-lang.in: Fix typo in comment.
-
- * Makefile.in (f/fini.o, f/proj-h.o): Don't use `$<' since
- not all makes support it (e.g. NeXT make), use explicit
- source name instead (with $(srcdir) and munging).
- (ASSERT_H): assert.h lives in source dir, not build dir.
-
-Thu Nov 16 12:47:50 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * com.c (ffecom_init_0): Fix dumb bug in code to produce
- warning message about non-32-bit-systems.
-
- * stc.c (ffestc_R501_item): Parenthesize test to make
- warning go away (and perhaps fix bug).
-
-Thu Nov 16 03:43:33 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * g77.c: Upgrade to 2.7.0's gcc.c.
- Fix -v to pass a temp name instead of "/dev/null" for "-o".
-
-Fri Nov 10 19:16:05 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * ste.c (ffeste_begin_iterdo_): Add Toon's change to
- make loops faster on some machines (implement termination
- condition as "--i >= 0" instead of "i-- > 0").
-
-Thu Nov 2 03:58:17 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Make-lang.in: Remove unnecessary $(exeext) a la cp/Make-lang.in.
-
- * com.c (ffecom_expr_): Restore old strategy for assignp variant
- of opSYMTER case...always return the ASSIGN version of var.
- That way, `-O -Wuninitialized' will catch "I=3;GOTO I;END"
- (though the diagnostic will refer to `__g77_ASSIGN_i').
-
- * com.c (ffecom_expr_power_integer_): For constant rhs case,
- wrap every new eval of lhs in save_expr() so it is clear to
- back end that MULT_EXPR(lhs,lhs) has identical operands,
- otherwise for an rhs like 32767 it generates around 65K pseudo
- registers, with which stupid_life_analysis cannot cope
- (due to reg_renumber in regs.h being `short *' instead of
- `int *').
-
- * com.c (ffecom_expr_): Speed up implementation of LOGICAL
- versions of opNOT, opAND, opOR, opXOR/opNEQV, and opEQV by
- assuming the values actually are kosher LOGICAL bit patterns.
- Also simplify code that implements some of the INTEGER versions
- of these.
-
- * com.c (skip_redundant_dir_prefix, read_name_map,
- ffecom_open_include_, signed_type, unsigned_type): Fold in
- changes to cccp.c made from 2.7.0 through ss-950826.
-
- * equiv.c (ffeequiv_layout_local_): Kill the equiv list
- if no syms in list.
-
- * expr.c (ffeexpr_reduced_eqop2_): Issue specific diagnostic
- regarding usage of .EQV./.NEQV. in preference to .EQ./.NE..
-
- * intrin.c: Add ERF and ERFC as generic intrinsics.
- intrin.def: Same.
-
- * sta.c (ffesta_save_, ffesta_second_): Whoever calls
- ffestd_exec_begin must also set ffesta_seen_first_exec = TRUE,
- and anytime stc sees an exec transition, it must do both.
- stc.c (ffestc_eof): Same.
-
- * stc.c (ffestc_promote_sfdummy_): If failed implicit typing
- or CHARACTER*(*) arg, after calling ffesymbol_error, don't
- reset info to ENTITY/DUMMY, because ffecom_sym_transform_
- doesn't expect such a thing with ANY/ANY type.
-
- * target.h (*logical*): Change some of these so they parallel
- changes in com.c, e.g. for _eqv_, use (l)==(r) instead of
- !!(l)==!!(r), to get a more faithful result.
-
-Fri Oct 27 07:06:59 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * com.c (ffecom_sym_transform_): Simplify code for local
- EQUIVALENCE case.
-
- * expr.c (ffeexpr_exprstack_push_unary_): Warn about two
- successive operators.
- (ffeexpr_exprstack_push_binary_): Warn about "surprising"
- operator precedence, as in "-2**2".
-
- * lang-options.h: Add -W(no-)surprising options.
-
- * parse.c (yyparse): Don't reset -fpedantic if not -pedantic.
-
- * top.c (ffe_decode_option): Support new -Wsurprising option.
- * top.h: Ditto.
-
-Mon Oct 23 09:14:15 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * com.c (ffecom_finish_symbol_transform_): Don't transform
- NONE/NONE (CHARACTER*(*)) vars, as these don't mean anything
- in debugging terms, and can't be turned into anything
- in the back end (so ffecom_sym_transform_ crashes on them).
-
- * com.c (ffecom_expr_): Change strategy for assignp variant
- of opSYMTER case...always return the original var unless
- it is not wide enough.
-
- * ste.c (ffeste_io_cilist_): Clarify diagnostic for ASSIGN
- involving too-narrow variable. This shouldn't happen, though.
- (ffeste_io_icilist_): Ditto.
- (ffeste_R838): Ditto.
- (ffeste_R839): Ditto.
-
-Thu Oct 19 03:21:20 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * com.c (ffecom_sym_transform_assign_): Set TREE_STATIC
- using the same decision-making process as used for their twin
- variables, so ASSIGN can last across RETURN/CALL as appropriate.
-
-Fri Sep 22 20:21:18 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Makefile.in: fini is a host program, so it needs a host-compiled
- version of proj.o, named proj-h.o. f/fini, f/fini.o, and
- f/proj-h.o targets updated accordingly.
-
- * com.c (__eprintf): New function.
-
-Wed Sep 20 02:26:36 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * lang-options.h: Add omitted -funix-intrinsics-* options.
-
- * malloc.c (malloc_find_inpool_): Check for infinite
- loop, crash if detected (user reports encountering
- them in some large programs, this might help track
- down the bugs).
-
-Thu Sep 7 13:00:32 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * com.c (lang_print_error_function): Don't dereference null
- pointer when outside any program unit.
- (ffecom_let_char_, ffecom_arg_ptr_to_expr): If catlist
- item or length ever error_mark_node, don't continue processing,
- since back-end functions like build_pointer_type crash on
- error_mark_node's (due to pushing bad obstacks, etc.).
-
-Wed Aug 30 15:58:35 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Version 0.5.16 released.
-
-Mon Aug 28 12:24:20 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * bad.c (ffebad_finish): Fix botched message when no places
- are printed (due to unknown line info, etc.).
-
- * std.c (ffestd_subr_labels_): Do a better job finding
- line info in the case of typeANY and diagnostics.
-
-Fri Aug 25 15:19:29 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * com.c (DECL_ARTIFICIAL): Surround all references to this
- macro with #if !BUILT_FOR_270 and #endif.
- (init_lex): Surround print_error_function decl with
- #if !BUILT_FOR_270 and #endif.
- (lang_init): Call new ffelex_hash_kludge function to solve
- problem with preprocessed files that have INCLUDE statements.
-
- * lex.c (ffelex_getc_): New function.
- (ffelex_cfelex_): Use ffelex_getc_ instead of getc in any
- paths of code that can be affected by ffelex_hash_kludge.
- Don't make an EOF token for unrecognized token; set token
- to NULL instead, to avoid problems when not initialized.
- (ffelex_hash_): Use ffelex_getc_ instead of getc in any
- paths of code that can be affected by ffelex_hash_kludge.
- Test token returned by ffelex_cfelex_ for NULL, meaning
- unrecognized token.
- Get rid of useless used_up variable.
- Don't do ffewhere stuff or kill any tokens if in
- ffelex_hash_kludge.
- (ffelex_file_fixed, ffelex_file_free): Use ffelex_getc_
- instead of getc in any paths of code that can be affected
- by ffelex_hash_kludge.
- (ffelex_hash_kludge): New function.
-
- * lex.h (ffelex_hash_kludge): New function.
-
-Wed Aug 23 15:17:40 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * com.c: Implement -f(no-)underscoring options by always
- compiling in code to do it, and having that code inhibit
- itself when -fno-underscoring is in effect. This option
- overrides -f(no-)f2c for this purpose; -f(no-)f2c returns
- to it's <=0.5.15 behavior of affecting only how code
- is generated, not how/whether names are mangled.
-
- * target.h: Redo specification of appending underscores so
- the macros are named "_default" instead of "_is" and the
- two-underscore macro defaults to 1.
-
- * top.c, top.h (underscoring): Add appropriate stuff
- for the -f(no-)underscoring options.
-
-Tue Aug 22 10:25:01 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * bad.c (ffebad_finish): Call report_error_function (in toplev.c)
- to better identify location of problem.
- Say "(continued):" instead of "(continued:)" for consistency.
-
- * com.c (ffecom_gen_sfuncdef_): Set and reset new
- ffecom_nested_entry_ variable to hold ffesymbol being compiled.
- (lang_print_error_function): New function from toplev.c.
- Use ffecom_nested_entry_ to help determine which name
- and kind-string to print.
- (ffecom_expr_intrinsic_): Handle EXIT and FLUSH invocations
- with different calling sequences than library functions.
- Have SIGNAL and SYSTEM push and pop calltemps, and convert
- their return values to the destination type (just in case).
- (FFECOM_rttypeINT_): New return type for `int', in case
- gcc/f/runtime/libF77/system_.c(system_) is really supposed
- to return `int' instead of `ftnint'.
-
- * com.h (report_error_function): Declare this.
-
- * equiv.c (ffeequiv_layout_local_): Don't forget to consider
- root variable itself as possible "first rooted variable",
- else might never set symbol and then crash later.
-
- * intrin.c (ffeintrin_check_exit_): Change to allow no args
- and rename to ffeintrin_check_int_1_o_ for `optional'.
- #define ffeintrin_check_exit_ and _flush_ to this new
- function, so intrin.def can refer to the appropriate names.
-
- * intrin.def (FFEINTRIN_impFLUSH): Validate using
- ffeintrin_check_flush_ so passing an INTEGER arg is allowed.
-
- * lex.c (ffelex_file_push_, ffelex_file_pop_): New functions
- to manage input_file_stack in gbe.
- (ffelex_hash_): Call new functions (instead of doing code).
- (ffelex_include_): Call new functions to update stack for
- INCLUDE (_hash_ handles cpp output of #include).
-
-Mon Aug 21 08:09:04 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Makefile.in: Put `-W' in front of every `-Wall', since
- 2.7.0 requires that to engage `-Wunused' for parameters.
-
- * com.c: Mark all parameters as artificial, so
- `-W -Wunused' doesn't complain about unused ones (since
- there's no way right not to individually specify attributes
- like `unused').
-
- * proj.h: Don't #define UNUSED if already defined, regardless
- of host compiler.
-
-Sun Aug 20 16:03:56 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * gbe/2.7.0.diff: Regenerate.
-
- * lang-options.h, lang-specs.h: If not __STDC__ (ANSI C),
- avoid doing anything, especially the stringizing in -specs.h.
-
-Thu Aug 17 03:36:12 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * lang-specs.h: Remove useless optional settings of -traditional,
- since -traditional is always set anyway.
-
-Wed Aug 16 16:56:46 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Make-lang.in (F2C_INSTALL_FLAG, F2CLIBOK): More
- control over whether to install f2c-related stuff.
- (install-f2c-*): New targets to install f2c-related
- stuff in system, not just gcc, directories.
-
- * com.c: Change calls to ffecom_get_invented_identifier
- to use generally more predictable names.
- Change calls to build_range_type to ensure consistency
- of types of operands.
- (ffecom_get_external_identifier_): Change to accept
- symbol info, not just text, so it can use f2c flag for
- symbol to decide whether to append underscore(s).
- (ffecom_get_identifier_): Don't change names if f2c flag
- off for compilation.
- (ffecom_type_permanent_copy_): Use same type for new max as
- used for min.
- (ffecom_notify_init_storage): Offline fixups for stand-alone.
-
- * data.c (ffedata_gather): Explicitly test for common block,
- since it's no longer always the case that a local EQUIVALENCE
- group has no symbol ptr (it now can, if a user-predictable
- "rooted" symbol has been identified).
-
- * equiv.c: Add some debugging stuff.
- (ffeequiv_layout_local_): Set symbol ptr with user-predictable
- "rooted" symbol, for giving the invented aggregate a
- predictable name.
-
- * g77.c (append_arg): Allow for 20 extra args instead of 10.
- (main): For version-only case, add `-fnull-version' and, unless
- explicitly omitted, `-lf2c -lm'.
-
- * lang-options.h: New "-fnull-version" option.
-
- * lang-specs.h: Support ".fpp" suffix for preprocessed source
- (useful for OS/2, MS-DOS, other case-insensitive systems).
-
- * stc.c (ffestc_R544_equiv_): Swap way lists are merged so this
- is consistent with the order in which lists are built, making
- user predictability of invented aggregate name much higher.
-
- * storag.c, storag.h (FFESTORAG_typeDUMMY): Delete this enum.
-
- * top.c: Accept, but otherwise ignore, `-fnull-version'.

-
- * INSTALL (f77-install-ok): Document the use of this file.
-
- * Make-lang.in (F77_INSTALL_FLAG): New flag to control
- whether to install an `f77' command (based on whether
- a file named `f77-install-ok' exists in the source or
- build directory) to replace the broken attempt to use
- comment lines to avoid installing `f77' (broken in the
- sense that it prevented installation of `g77').
-
-Mon Aug 7 06:14:26 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * DOC: Add new sections for g77 & gcc compiler options,
- source code form, and types, sizes and precisions.
- Remove lots of old "delta-version" info, or at least
- summarize it.
-
- * INSTALL: Add info here that used to be in DOC.
- Other changes.
-
- * g77.c (lookup_option, main): Check for --print-* options,
- so we avoid adding version-determining stuff.
-
-Wed Jul 26 15:51:03 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Make-lang.in, Makefile.in (input.j, INPUT_H): New file.

-
- * bad.c (ffebad_here): Okay to use unknown line/col.
-
- * compilers.h (@f77-cpp-input): Remove -P option now that
- # directives are handled by f771. Update other options
- to be more consistent with @c in gcc/gcc.c. Don't run f771
- if -E specified, etc., a la @c.
- (@f77): Don't run f771 if -E specified, etc., a la @c.
-
- * config-lang.in: Avoid use of word "guaranteed".

- following successful INCLUDE.
- (ffelex_next_line_): New function that does chunk of code
- seen in several places elsewhere in the lexers.
- (ffelex_file_fixed): Delay finishing statement until source
- line is registered with ffewhere, so INCLUDE processing
- picks up the info correctly.
- Okay to kill or use unknown line/col objects now.
- Handle HASH (#) lines.
- Reorder tests for insubstantial lines to put most frequent
- occurrences at top, for possible minor speedup.
- Some general consolidation of code.
- (ffelex_file_free): Handle HASH (#) lines.
- Okay to kill or use unknown line/col objects now.
- Some general consolidation of code.
- (ffelex_init_1): Detect HASH (#) lines.

-
- * stw.c (ffestw_update): Okay to kill unknown line/col objects
- now.
-
- * target.h (FFETARGET_okREALQUAD, FFETARGET_okCOMPLEXDOUBLE,
- FFETARGET_okCOMPLEXQUAD): #define these appropriately.

-
-Mon Jul 17 03:04:09 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * com.c (ffecom_sym_transform_): Set DECL_IN_SYSTEM_HEADER
- flag for any local vars used as stmtfunc dummies or DATA
- implied-DO iter vars, so no -Wunused warnings are produced
- for them (a la f2c).
- (ffecom_init_0): Do "extern int xargc;" for IARGC() intrinsic.
- Warn if target machine not 32 bits, since g77 isn't yet
- working on them at all well.
-
- * expr.c (ffeexpr_sym_lhs_call_, ffeexpr_sym_lhs_data_,
- ffeexpr_sym_lhs_extfunc_, ffeexpr_sym_rhs_actualarg_,
- ffeexpr_sym_rhs_let_, ffeexpr_paren_rhs_let_): Don't
- gratuitously set attr bits that don't apply just
- to avoid null set meaning error; instead, use explicit
- error flag, and allow null attr set, to
- fix certain bugs discovered by looking at this code.
-
- * g77.c: Major changes to improve support for gcc long options,
- to make `g77 -v' report more useful info, and so on.
-
-Mon Jul 3 14:49:16 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * DOC, com.c, intrin.h, intrin.c, intrin.def, target.h, top.c,

-
-Tue Jun 27 23:01:05 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * bld.c, bld.h (ffebld_constant_pool,
- ffebld_constant_character_pool): Use a single macro (the
- former) to access the pool for allocating constants, instead
- of latter in public and FFEBLD_CONSTANT_POOL_ internally
- in bld.c (which was the only one that was correct before
- these changes). Add verification of integrity of certain
- heap-allocated areas.
-
- * com.c (ffecom_overlap_, ffecom_args_overlap_,
- ffecom_tree_canonize_ptr_, ffecom_tree_canonize_ref_): New
- functions to optimize calling COMPLEX and, someday, CHARACTER
- functions requiring additional argument to be passed.
- (ffecom_call_, ffecom_call_binop_, ffecom_expr_,
- ffecom_expr_intrinsic_): Change calling
- sequences to include more info on possible destination.
- (ffecom_expr_intrinsic_): Add ERF(), ERFC(), and EXIT()
- intrinsic code.
- (ffecom_sym_transform_): For assumed-size arrays, set high
- bound to highest possible value instead of low bound, to
- improve validity of overlap checking.
- (duplicate_decls): If olddecl and newdecl are the same,
- don't do any munging, just return affirmative.
-
- * expr.c: Change ffecom_constant_character_pool() to
- ffecom_constant_pool().
-
- * info.c (ffeinfo_new): Compile this version if not being
- compiled by GNU C.
-
- * info.h (ffeinfo_new): Don't define macro if not being

-
- * malloc.c, malloc.h (malloc_verify_*): New functions to verify
- integrity of heap-storage areas.
-
- * stc.c (ffestc_R834, ffestc_R835): Handle possibility that
- an enclosing DO won't have a construct name even when the
- CYCLE/EXIT does (i.e. without dereferencing NULL).
-
- * target.c, target.h (ffetarget_verify_character1): New function
- to verify integrity of heap storage used to hold character constant.
-
-Thu Jun 22 15:36:39 1995 Howard Gordon (flash@super.org)
-
- * stp.h (ffestpVxtcodeIx): Fix typo in typedef for this.
-
-Mon May 29 15:22:31 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * *: Make all sorts of changes to accommodate upcoming gcc-2.7.0.
- I didn't keep track of them, nor just when I made them, nor
- when I (much later, probably in early August 1995) modified
- them so they could properly handle both 2.7.0 and 2.6.x.
-
- * com.c (ffecom_expr_power_integer_): Don't expand_start_stmt_expr
- if transforming dummy args, because the back end cannot handle
- that (it's rejected by the gcc front end), just generate
- call to run-time library.
- Back out changes in 0.5.15 because more temporaries might be
- needed anyway (for COMPLEX**INTEGER).
- (ffecom_push_tempvar): Remove inhibitor.
- Around start_decl and finish_decl (in particular, arround
- expand_decl, which is called by them), push NULL_TREE into
- sequence_rtl_expr, an external published by gcc/function.c.
- This makes sure the temporary is truly in the function's
- context, not the inner context of a statement-valued expression.
- (I think the back end is inconsistent here, but am not
- interested in convincing the gbe maintainers about this now.)
- (pushdecl): Make sure that when pushing PARM_DECLs, nothing
- other than them are pushed, as happened for 0.5.15 and which,
- if done for other reasons not fixed here, might well indicate
- some other problem -- so crash if it happens.
-
- * equiv.c (ffeequiv_layout_local_): If the local equiv group
- has a non-nil COMMON field, it should mean that an error has
- occurred and been reported, so just trash the local equiv
- group and do nothing.
-
- * stc.c (ffestc_promote_sfdummy_): Set sfdummy arg state to
- UNDERSTOOD so above checking for duplicate args actually
- works, and so we don't crash later in pushdecl.
-
- * ste.c (ffeste_R1001): Set initial value only for VAR_DECLs,
- not for, e.g., LABEL_DECLs, which the FORMAT label can be
- if it was previously treated as an executable label.
-
-Sat May 20 01:53:53 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * com.c (ffecom_sym_transform_): For adjustable arrays,
- pass high bound through variable_size in case its primaries
- are changed (dumb0.f, and this might also improve
- performance so it approaches f2c|gcc).
-
-Fri May 19 11:00:36 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Version 0.5.15 released.
-
- * com.c (ffecom_expr_power_integer_): Push temp vars
- before expanding a statement expression, since that seems
- to cause temp vars to be "forgotten" after the end of the
- expansion in the back end. Disallow more temp-var
- pushing during such an expansion, just in case.
- (ffecom_push_tempvar): Crash if a new variable needs to be

-
- * ste.c (ffeste_begin_iterdo_): Use correct algorithm for

- contribute to building f771.
-
- * Makefile.in (dircheck): Remove/replace with f/Makefile, because

- anyway).

- (ffecom_expr_): Don't convert result from ffecom_tree_divide_.
- (ffecom_tree_divide_): Add tree_type argument, have all callers
- pass one, and don't convert right-hand operand to it (this is

- code used in ffecom_expr_ as possible).
-
- * lex.c: Maintain lineno and input_filename the way the gcc
- lexer does.
-
- * std.c (ffestd_exec_end): Save and restore lineno and

-
-Wed Apr 5 14:15:44 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * lex.c: Change to allocate text for tokens only when actually

- Remove some old, obsolete code.
- Clean up layout of entire file to improve formatting,
- readability, etc.

- directly off the command line instead of making the latter
- two out of the first.
-
- * lex.c: Improve tab handling for both fixed and free source

-Fri Feb 17 03:35:19 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Version 0.5.8 released.
-
- * INSTALL: In quick-build case, list g77 target first so g77
- gets installed. Also, explain that gcc gets built and installed
- as well, even though this isn't really what we want (and maybe
- we'll find a way around this someday).
-
-Fri Feb 17 02:35:41 1995 Craig Burley (burley@gnu.ai.mit.edu)
-

-
- * Makefile.in (CONFIG_H, HCONFIG_H, TCONFIG_H, TM_H): Don't

- a note explaining what these macros are about.
- Update dependencies via deps-kinda.
-
- * README.NEXTSTEP: Credit Toon, and per his request, add his
- email address.
-
- * com.h (FFECOM_DETERMINE_TYPES): #include "config.j".
-
- * config.j, convert.j, flags.j, hconfig.j, rtl.j, tconfig.j,
- tm.j, tree.j: Don't #include if already done.
-
- * convert.j: #include "tree.j" first, as convert.h clearly depends
- on trees being defined.
-
- * rtl.j: #include "config.j" first, since there's some stuff
- in rtl.h that assumes it has been #included.
-
- * tree.j: #include "config.j" first, or real.h makes inconsistent
- decision about return type of ereal_atof, leading to bugs, and
- because tree.h/real.h assume config.h already included.
-

-
-Sat Feb 11 20:56:02 1995 Craig Burley (burley@gnu.ai.mit.edu)

-
- * ste.c: In I/O code tests for item arrayness, sort of revert
- to much earlier code that tests original exp, but also check
- in newer way just in case. Newer way alone treated FOO(1:40)
- as an array, not sure why older way alone didn't work, but I
- think maybe it was when diagnosed code was involved, and
- since there are now checks for error_mark_node, maybe the old
- way alone would work. But better to be safe; both original
- ffebld exp _and_ the transformed tree must indicate an array
- for the size-determination code to be used, else just 1/2 elements
- assumed. And this text is for EMACS: (foo at bar).
-
-Fri Feb 10 11:05:50 1995 Craig Burley (burley@gnu.ai.mit.edu)
-
- * ste.c: In many cases, surround statement-expansion code
- with ffecom_push_calltemps () and ffecom_pop_calltemps ()
- so COMPLEX-returning functions can have temporaries pushed
- in "auto-pop" mode and have them auto-popped at the end of
- the statement.

- Create f/runtime directory tree iff not building in source
- directory.
-
- * Makefile.in (srcdir): Append slash so we get the right value when

- (hopefully for clearer, more maintainable code), including
- consistency checks on arg count just in case.
-

- stuff.
- Remove consistency tests that cause compiler warnings.

-
- * com.c: Increase FFECOM_sizeMAXSTACKITEM, and if 0 or undefined
- when checked to determine where to put entity, treat as infinite.
- Rewrite temporary mechanism to be based on trees instead of
- ffeinfo stuff, and make it much simpler. Change interface
- accordingly.
- Fixes to better track types of things, make appropriate
- conversions, etc. E.g. when making an arg for a libf2c
- function, make sure it's of the right type (such as ftnlen).
- Delete opBACKEND transformation code.
- (ffecom_init_0): Smoother initialization of types, especially
- paying attention to using consistent rules for making INTEGER,
- REAL, DOUBLE PRECISION, etc., and for deciding their "*N"
- and kind values that will work across all g77 platforms.
- No longer require per-target configuration info in target.h
- or config/*/*; use new type module to store size, alignment.
- (ffecom_member_phase2): Declare COMMON/EQUIVALENCE group members
- so debugger sees them.

-
- * ste.c: Update to handle new interface for
- ffecom_push/pop_tempvar.
- Fixes to better track types of things.
- Fixes to not crash for certain diagnosed constructs.
- (ffeste_begin_iterdo_): Check only constants for overflow to avoid

- for iteration count.
-
- * stw.h: Track DO iteration count temporary variable.
-
- * symbol.c: Remove consistency tests that cause compiler warnings.

-
-Wed Nov 23 15:22:53 1994 Dave Love <d.love@dl.ac.uk>
-
- * bad.c (ffebad_finish): kluge to fool emacs19 into finding errors:
- add trailing space to <file>:<line>:
-

-
- * runtime/libF77/signal_.c (RETSIGTYPE): added

-
- * Makefile.in (compiler): add runtime
-
- * config-lang.in (stagestuff): add libf2c.a to stagestuff
-
- * Make-lang.in:
- G77STAGESTUFF <- MORESTAGESTUFF
- f77-runtime: new target, plus supporting ones
-
- * runtime: add the directory, containing libI77, libF77 and autoconf
- stuff
-
- * g++.1: remove
-
- * g77.1: minor fixes
-
-Thu Nov 17 15:18:05 1994 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Version 0.5.2 released.
-
- * bad.def: Modify wording of FFEBAD_UNIMPL_STMT to indicate
- that it covers a wide array of possible problems (that, someday,
- should be handled via separate diagnostics).
-
- * lex.c: Allow $ in identifiers if -fdollar-ok.
- * top.c: Support -fdollar-ok.
- * top.h: Support -fdollar-ok.
- * target.h: Support -fdollar-ok.
- * DOC: Describe -fdollar-ok.
-
- * std.c (ffestd_R1229_finish): Fix bug so stand-alone build works.
- * ste.c (ffeste_R819A): Fix bug so stand-alone build works.
-
- * Make: Improvements for stand-alone build.
-
- * Makefile.in: Fix copyright text at top of file.
-
- * LINK, SRCS, UNLINK: Removed. Not particularly useful now that
- g77 sources live in their own subdirectory.
-
- * g77.c (main): Cast arg to bzero to avoid warning. (This is
- identical to Kenner's fix to cp/g++.c.)
-
- * gbe/: New subdirectory, to contain .diff files for various
- versions of the GNU CC back end.
-
- * gbe/README: New file.
- * gbe/2.6.2.diff: New file.
-
-Tue Nov 8 10:23:10 1994 Dave Love <d.love@dl.ac.uk>
-
- * Make-lang.in: don't install as f77 as well as g77 to avoid
- confusion with system's compiler (especially while testing)
-
- * g77.c (main): use -lf2c and -lm; fix sense of test for .f/.F files
-
-Fri Oct 28 09:45:00 1994 Craig Burley (burley@gnu.ai.mit.edu)
-
- * Version 0.5.1 released.

-# This dance is all about producing accurate documentation for g77's
-# intrinsics with minimum fuss. f/ansify appends "\n\" to C strings
-# so ANSI C compilers can compile f/intdoc.h -- gcc can compile f/intdoc.in
-# directly, if f/intdoc.c #include'd that, but we don't want to force
-# people to install gcc just to build the documentation. We use the
-# C format for f/intdoc.in in the first place to allow a fairly "free",
-# but widely known format for documentation -- basically anyone who knows
-# how to write texinfo source and enclose it in C constants can handle
-# it, and f/ansify allows them to not even end lines with "\n\". So,
-# essentially, the C preprocessor and compiler are used to enter the
-# document snippets into a data base via name lookup, rather than duplicating
-# that kind of code here. And we use f/intdoc.c instead of straight
-# texinfo in the first place so that as much information as possible
-# contained in f/intrin.def can be inserted directly and reliably into
-# the documentation. That's better than replicating it, because it
-# reduces the likelihood of discrepancies between the docs and the compiler
-# itself, which uses f/intrin.def; in fact, many bugs in f/intrin.def have
-# been found only upon reading the documentation that was automatically
-# produced from it.
-
-# If the documentation files depended on executables in the build
-# tree, there'd be no way to ship a source tree with the documentation
-# already generated such that `make' wouldn't attempt to rebuild it.
-# So, we punt and arrange for the documentation files to depend on the
-# dependencies of the executables, not on the executables themselves.
-# But then, we have to build the executables explicitly in their build
-# rules.

- Like _put, but just returns the pointers to the beginnings of the
- array and the constant and returns the size (the amount of info to
- copy). The idea is that the caller can use memcpy to accomplish the
- same thing as _put (though slower), or the caller can use a different
- function that swaps bytes, words, etc for a different target machine.
- Also, the type of the array may be different from the type of the
- constant; the array type is used to determine the meaning (scale) of
- the offset field (to calculate the array pointer), the constant type is
- used to determine the constant pointer and the size (amount of info to
- copy). */

-and might not accurately reflect the @code{g77} code base
-of which it is a part.
-Efforts are made to keep it somewhat up-to-date,
-but they are particularly concentrated
-on any version of this information
-that is distributed as part of a @emph{released} @code{g77}.
-
-In particular, while this information is intended to apply to
-the @value{which-g77} version of @code{g77},
-only an official @emph{release} of that version
-is expected to contain documentation that is
-most consistent with the @code{g77} product in that version.
-@end ifset
-
-An online, ``live'' version of this document
-(derived directly from the mainline, development version
-of @code{g77} within @code{gcc})
-is available via
-@uref{http://gcc.gnu.org/onlinedocs/g77/Trouble.html}.
-Follow the ``Known Bugs'' link.
-
-The following information was last updated on @value{last-update-bugs}:
-
-@itemize @bullet
-@item
-@code{g77} fails to warn about
-use of a ``live'' iterative-DO variable
-as an implied-DO variable
-in a @code{WRITE} or @code{PRINT} statement
-(although it does warn about this in a @code{READ} statement).
-
-@item
-Something about @code{g77}'s straightforward handling of
-label references and definitions sometimes prevents the GBE
-from unrolling loops.
-Until this is solved, try inserting or removing @code{CONTINUE}
-statements as the terminal statement, using the @code{END DO}
-form instead, and so on.
-
-@item
-Some confusion in diagnostics concerning failing @code{INCLUDE}
-statements from within @code{INCLUDE}'d or @code{#include}'d files.
-
-@cindex integer constants
-@cindex constants, integer
-@item
-@code{g77} assumes that @code{INTEGER(KIND=1)} constants range
-from @samp{-2**31} to @samp{2**31-1} (the range for
-two's-complement 32-bit values),
-instead of determining their range from the actual range of the
-type for the configuration (and, someday, for the constant).
-
-Further, it generally doesn't implement the handling
-of constants very well in that it makes assumptions about the
-configuration that it no longer makes regarding variables (types).
-
-Included with this item is the fact that @code{g77} doesn't recognize
-that, on IEEE-754/854-compliant systems, @samp{0./0.} should produce a NaN
-and no warning instead of the value @samp{0.} and a warning.

-@cindex speed, of compiler
-@cindex compiler memory usage
-@cindex memory usage, of compiler
-@cindex large aggregate areas
-@cindex initialization, bug
-@cindex DATA statement
-@cindex statements, DATA
-@item
-@code{g77} uses way too much memory and CPU time to process large aggregate
-areas having any initialized elements.
-
-For example, @samp{REAL A(1000000)} followed by @samp{DATA A(1)/1/}
-takes up way too much time and space, including
-the size of the generated assembler file.
-
-Version 0.5.18 improves cases like this---specifically,
-cases of @emph{sparse} initialization that leave large, contiguous
-areas uninitialized---significantly.
-However, even with the improvements, these cases still
-require too much memory and CPU time.
-
-(Version 0.5.18 also improves cases where the initial values are
-zero to a much greater degree, so if the above example
-ends with @samp{DATA A(1)/0/}, the compile-time performance
-will be about as good as it will ever get, aside from unrelated
-improvements to the compiler.)
-
-Note that @code{g77} does display a warning message to
-notify the user before the compiler appears to hang.
-@ifset DOC-G77
-A warning message is issued when @code{g77} sees code that provides
-initial values (e.g. via @code{DATA}) to an aggregate area (@code{COMMON}
-or @code{EQUIVALENCE}, or even a large enough array or @code{CHARACTER}
-variable)
-that is large enough to increase @code{g77}'s compile time by roughly
-a factor of 10.
-
-This size currently is quite small, since @code{g77}
-currently has a known bug requiring too much memory
-and time to handle such cases.
-In @file{@value{path-g77}/data.c}, the macro
-@code{FFEDATA_sizeTOO_BIG_INIT_} is defined
-to the minimum size for the warning to appear.
-The size is specified in storage units,
-which can be bytes, words, or whatever, on a case-by-case basis.
-
-After changing this macro definition, you must
-(of course) rebuild and reinstall @code{g77} for
-the change to take effect.
-
-Note that, as of version 0.5.18, improvements have
-reduced the scope of the problem for @emph{sparse}
-initialization of large arrays, especially those
-with large, contiguous uninitialized areas.
-However, the warning is issued at a point prior to
-when @code{g77} knows whether the initialization is sparse,
-and delaying the warning could mean it is produced
-too late to be helpful.
-
-Therefore, the macro definition should not be adjusted to
-reflect sparse cases.
-Instead, adjust it to generate the warning when densely
-initialized arrays begin to cause responses noticeably slower
-than linear performance would suggest.

-@cindex code, displaying main source
-@cindex displaying main source code
-@cindex debugging main source code
-@cindex printing main source
-@item
-When debugging, after starting up the debugger but before being able
-to see the source code for the main program unit, the user must currently
-set a breakpoint at @code{MAIN__} (or @code{MAIN___} or @code{MAIN_} if
-@code{MAIN__} doesn't exist)
-and run the program until it hits the breakpoint.
-At that point, the
-main program unit is activated and about to execute its first
-executable statement, but that's the state in which the debugger should
-start up, as is the case for languages like C.
-
-@cindex debugger
-@item
-Debugging @code{g77}-compiled code using debuggers other than
-@code{gdb} is likely not to work.
-
-Getting @code{g77} and @code{gdb} to work together is a known
-problem---getting @code{g77} to work properly with other
-debuggers, for which source code often is unavailable to @code{g77}
-developers, seems like a much larger, unknown problem,
-and is a lower priority than making @code{g77} and @code{gdb}
-work together properly.
-
-On the other hand, information about problems other debuggers
-have with @code{g77} output might make it easier to properly
-fix @code{g77}, and perhaps even improve @code{gdb}, so it
-is definitely welcome.
-Such information might even lead to all relevant products
-working together properly sooner.
-
-@cindex Alpha, support
-@cindex support, Alpha
-@item
-@code{g77} doesn't work perfectly on 64-bit configurations
-such as the Digital Semiconductor (``DEC'') Alpha.
-
-This problem is largely resolved as of version 0.5.23.
-
-@cindex padding
-@cindex structures
-@cindex common blocks
-@cindex equivalence areas
-@item
-@code{g77} currently inserts needless padding for things like
-@samp{COMMON A,IPAD} where @samp{A} is @code{CHARACTER*1} and @samp{IPAD}
-is @code{INTEGER(KIND=1)} on machines like x86,
-because the back end insists that @samp{IPAD}
-be aligned to a 4-byte boundary,
-but the processor has no such requirement
-(though it is usually good for performance).
-
-The @code{gcc} back end needs to provide a wider array
-of specifications of alignment requirements and preferences for targets,
-and front ends like @code{g77} should take advantage of this
-when it becomes available.
-
-@cindex complex performance
-@cindex aliasing
-@item
-The @code{libf2c} routines that perform some run-time
-arithmetic on @code{COMPLEX} operands
-were modified circa version 0.5.20 of @code{g77}
-to work properly even in the presence of aliased operands.
-
-While the @code{g77} and @code{netlib} versions of @code{libf2c}
-differ on how this is accomplished,
-the main differences are that we believe
-the @code{g77} version works properly
-even in the presence of @emph{partially} aliased operands.
-
-However, these modifications have reduced performance
-on targets such as x86,
-due to the extra copies of operands involved.

- Description:
- Contains compiler-specific functions.
-
- Modifications:
-*/
-
-/* Understanding this module means understanding the interface between
- the g77 front end and the gcc back end (or, perhaps, some other
- back end). In here are the functions called by the front end proper
- to notify whatever back end is in place about certain things, and
- also the back-end-specific functions. It's a bear to deal with, so
- lately I've been trying to simplify things, especially with regard
- to the gcc-back-end-specific stuff.
-
- Building expressions generally seems quite easy, but building decls
- has been challenging and is undergoing revision. gcc has several
- kinds of decls:
-
- TYPE_DECL -- a type (int, float, struct, function, etc.)
- CONST_DECL -- a constant of some type other than function
- LABEL_DECL -- a variable or a constant?
- PARM_DECL -- an argument to a function (a variable that is a dummy)
- RESULT_DECL -- the return value of a function (a variable)
- VAR_DECL -- other variable (can hold a ptr-to-function, struct, int, etc.)
- FUNCTION_DECL -- a function (either the actual function or an extern ref)
- FIELD_DECL -- a field in a struct or union (goes into types)
-
- g77 has a set of functions that somewhat parallels the gcc front end
- when it comes to building decls:
-
- Internal Function (one we define, not just declare as extern):
- if (is_nested) push_f_function_context ();
- start_function (get_identifier ("function_name"), function_type,
- is_nested, is_public);
- // for each arg, build PARM_DECL and call push_parm_decl (decl) with it;
- store_parm_decls (is_main_program);
- ffecom_start_compstmt ();
- // for stmts and decls inside function, do appropriate things;
- ffecom_end_compstmt ();
- finish_function (is_nested);
- if (is_nested) pop_f_function_context ();
-
- Everything Else:
- tree d;
- tree init;
- // fill in external, public, static, &c for decl, and
- // set DECL_INITIAL to error_mark_node if going to initialize
- // set is_top_level TRUE only if not at top level and decl
- // must go in top level (i.e. not within current function decl context)
- d = start_decl (decl, is_top_level);
- init = ...; // if have initializer
- finish_decl (d, init, is_top_level);

- /* Determine whether array is conditionally adjustable,
- to decide whether back-end magic is needed.
-
- Normally the front end uses the back-end function
- variable_size to wrap SAVE_EXPR's around expressions
- affecting the size/shape of an array so that the
- size/shape info doesn't change during execution
- of the compiled code even though variables and
- functions referenced in those expressions might.
-
- variable_size also makes sure those saved expressions
- get evaluated immediately upon entry to the
- compiled procedure -- the front end normally doesn't
- have to worry about that.
-
- However, there is a problem with this that affects
- g77's implementation of entry points, and that is
- that it is _not_ true that each invocation of the
- compiled procedure is permitted to evaluate
- array size/shape info -- because it is possible
- that, for some invocations, that info is invalid (in
- which case it is "promised" -- i.e. a violation of
- the Fortran standard -- that the compiled code
- won't reference the array or its size/shape
- during that particular invocation).
-
- To phrase this in C terms, consider this gcc function:
-
- void foo (int *n, float (*a)[*n])
- {
- // a is "pointer to array ...", fyi.
- }
-
- Suppose that, for some invocations, it is permitted
- for a caller of foo to do this:
-
- foo (NULL, NULL);
-
- Now the _written_ code for foo can take such a call
- into account by either testing explicitly for whether
- (a == NULL) || (n == NULL) -- presumably it is
- not permitted to reference *a in various fashions
- if (n == NULL) I suppose -- or it can avoid it by
- looking at other info (other arguments, static/global
- data, etc.).
-
- However, this won't work in gcc 2.5.8 because it'll
- automatically emit the code to save the "*n"
- expression, which'll yield a NULL dereference for
- the "foo (NULL, NULL)" call, something the code
- for foo cannot prevent.
-
- g77 definitely needs to avoid executing such
- code anytime the pointer to the adjustable array
- is NULL, because even if its bounds expressions
- don't have any references to possible "absent"
- variables like "*n" -- say all variable references
- are to COMMON variables, i.e. global (though in C,
- local static could actually make sense) -- the
- expressions could yield other run-time problems
- for allowably "dead" values in those variables.
-
- For example, let's consider a more complicated
- version of foo:
-
- extern int i;
- extern int j;
-
- void foo (float (*a)[i/j])
- {
- ...
- }
-
- The above is (essentially) quite valid for Fortran
- but, again, for a call like "foo (NULL);", it is
- permitted for i and j to be undefined when the
- call is made. If j happened to be zero, for
- example, emitting the code to evaluate "i/j"
- could result in a run-time error.
-
- Offhand, though I don't have my F77 or F90
- standards handy, it might even be valid for a
- bounds expression to contain a function reference,
- in which case I doubt it is permitted for an
- implementation to invoke that function in the
- Fortran case involved here (invocation of an
- alternate ENTRY point that doesn't have the adjustable
- array as one of its arguments).
-
- So, the code that the compiler would normally emit
- to preevaluate the size/shape info for an
- adjustable array _must not_ be executed at run time
- in certain cases. Specifically, for Fortran,
- the case is when the pointer to the adjustable
- array == NULL. (For gnu-ish C, it might be nice
- for the source code itself to specify an expression
- that, if TRUE, inhibits execution of the code. Or
- reverse the sense for elegance.)
-
- (Note that g77 could use a different test than NULL,
- actually, since it happens to always pass an
- integer to the called function that specifies which
- entry point is being invoked. Hmm, this might
- solve the next problem.)
-
- One way a user could, I suppose, write "foo" so
- it works is to insert COND_EXPR's for the
- size/shape info so the dangerous stuff isn't
- actually done, as in:
-
- void foo (int *n, float (*a)[(a == NULL) ? 0 : *n])
- {
- ...
- }
-
- The next problem is that the front end needs to
- be able to tell the back end about the array's
- decl _before_ it tells it about the conditional
- expression to inhibit evaluation of size/shape info,
- as shown above.
-
- To solve this, the front end needs to be able
- to give the back end the expression to inhibit
- generation of the preevaluation code _after_
- it makes the decl for the adjustable array.
-
- Until then, the above example using the COND_EXPR
- doesn't pass muster with gcc because the "(a == NULL)"
- part has a reference to "a", which is still
- undefined at that point.
-
- g77 will therefore use a different mechanism in the
- meantime. */

-/* Implement COMMON area in back end.
-
- Because COMMON-based variables can be referenced in the dimension
- expressions of dummy (adjustable) arrays, and because dummies
- (in the gcc back end) need to be put in the outer binding level
- of a function (which has two binding levels, the outer holding
- the dummies and the inner holding the other vars), special care
- must be taken to handle COMMON areas.
-
- The current strategy is basically to always tell the back end about
- the COMMON area as a top-level external reference to just a block
- of storage of the master type of that area (e.g. integer, real,
- character, whatever -- not a structure). As a distinct action,
- if initial values are provided, tell the back end about the area
- as a top-level non-external (initialized) area and remember not to
- allow further initialization or expansion of the area. Meanwhile,
- if no initialization happens at all, tell the back end about
- the largest size we've seen declared so the space does get reserved.
- (This function doesn't handle all that stuff, but it does some
- of the important things.)
-
- Meanwhile, for COMMON variables themselves, just keep creating
- references like *((float *) (&common_area + offset)) each time
- we reference the variable. In other words, don't make a VAR_DECL
- or any kind of component reference (like we used to do before 0.4),
- though we might do that as well just for debugging purposes (and
- stuff the rtl with the appropriate offset expression). */

- be retracted (undone) or committed (ratified), at which time the
- appropriate ffecom_sym_retract or _commit function will be called
- for that function.
-
- If the backend has its own backtracking mechanism, great, use it so that
- committal is a simple operation. Though it doesn't make much difference,
- I suppose: the reason for tentative symbol evolution in the FFE is to
- enable error detection in weird incorrect statements early and to disable
- incorrect error detection on a correct statement. The backend is not
- likely to introduce any information that'll get involved in these
- considerations, so it is probably just fine that the implementation
- model for this fn and for _exec_transition is to not do anything
- (besides the required FFE stuff) if ffesymbol_retractable() returns TRUE
- and instead wait until ffecom_sym_commit is called (which it never
- will be as long as we're using ambiguity-detecting statement analysis in
- the FFE, which we are initially to shake out the code, but don't depend
- on this), otherwise go ahead and do whatever is needed.
-
- In essence, then, when this fn and _exec_transition get called while
- backtracking is enabled, a general mechanism would be to flag which (or
- both) of these were called (and in what order? neat question as to what
- might happen that I'm too lame to think through right now) and then when
- _commit is called reproduce the original calling sequence, if any, for
- the two fns (at which point backtracking will, of course, be disabled). */

-
- The whole point here is to end up with a situation where each and every
- ..._TYPE node the compiler creates will be uniquely associated with
- AT MOST one node representing a typedef name. This way, even though
- the compiler substitutes corresponding ..._TYPE nodes for TYPE_DECL
- (i.e. "typedef name") nodes very early on, later parts of the
- compiler can always do the reverse translation and get back the
- corresponding typedef name. For example, given:
-
- typedef struct S MY_TYPE; MY_TYPE object;
-
- Later parts of the compiler might only know that `object' was of type
- `struct S' if it were not for code just below. With this code
- however, later parts of the compiler see something like:
-
- struct S' == struct S typedef struct S' MY_TYPE; struct S' object;
-
- And they can then deduce (from the node for type struct S') that the
- original object declaration was:
-
- MY_TYPE object;
-
- Being able to do this is important for proper support of protoize, and
- also for generating precise symbolic debugging information which
- takes full account of the programmer's (typedef) vocabulary.
-
- Obviously, we don't want to generate a duplicate ..._TYPE node if the
- TYPE_DECL node that we are now processing really represents a
- standard built-in type.
-
- Since all standard types are effectively declared at line zero in the
- source file, we can easily check to see if we are working on a
- standard type by checking the current value of lineno. */

- single ffebld object specifying the entire expression and the first
- lexer token that is not considered part of the expression. This caller-
- supplied routine itself returns a lexer-token handling routine. Thus,

-The current directory layout includes the following:
-
-@table @file
-@item @var{srcdir}/gcc/
-Non-g77 files in gcc
-
-@item @var{srcdir}/gcc/f/
-GNU Fortran front end sources
-
-@item @var{srcdir}/libf2c/

-Additional interfaces to Unix @code{libc} for @code{libg2c}
-@end table
-
-Components of note in @code{g77} are described below.
-
-@file{f/} as a whole contains the source for @code{g77},
-while @file{libf2c/} contains a portion of the separate program
-@code{f2c}.
-Note that the @code{libf2c} code is not part of the program @code{g77},
-just distributed with it.
-
-@file{f/} contains text files that document the Fortran compiler, source
-files for the GNU Fortran Front End (FFE), and some other stuff.
-The @code{g77} compiler code is placed in @file{f/} because it,
-along with its contents,
-is designed to be a subdirectory of a @code{gcc} source directory,
-@file{gcc/},
-which is structured so that language-specific front ends can be ``dropped
-in'' as subdirectories.
-The C++ front end (@code{g++}), is an example of this---it resides in
-the @file{cp/} subdirectory.
-Note that the C front end (also referred to as @code{gcc})
-is an exception to this, as its source files reside
-in the @file{gcc/} directory itself.
-
-@file{libf2c/} contains the run-time libraries for the @code{f2c} program,
-also used by @code{g77}.
-These libraries normally referred to collectively as @code{libf2c}.
-When built as part of @code{g77},
-@code{libf2c} is installed under the name @code{libg2c} to avoid
-conflict with any existing version of @code{libf2c},
-and thus is often referred to as @code{libg2c} when the
-@code{g77} version is specifically being referred to.
-
-The @code{netlib} version of @code{libf2c/}
-contains two distinct libraries,
-@code{libF77} and @code{libI77},
-each in their own subdirectories.
-In @code{g77}, this distinction is not made,
-beyond maintaining the subdirectory structure in the source-code tree.
-
-@file{libf2c/} is not part of the program @code{g77},
-just distributed with it.
-It contains files not present
-in the official (@code{netlib}) version of @code{libf2c},
-and also contains some minor changes made from @code{libf2c},
-to fix some bugs,
-and to facilitate automatic configuration, building, and installation of
-@code{libf2c} (as @code{libg2c}) for use by @code{g77} users.
-See @file{libf2c/README} for more information,
-including licensing conditions
-governing distribution of programs containing code from @code{libg2c}.
-
-@code{libg2c}, @code{g77}'s version of @code{libf2c},
-adds Dave Love's implementation of @code{libU77},
-in the @file{libf2c/libU77/} directory.
-This library is distributed under the
-GNU Library General Public License (LGPL)---see the
-file @file{libf2c/libU77/COPYING.LIB}
-for more information,
-as this license
-governs distribution conditions for programs containing code
-from this portion of the library.

-@item f/g77.info*
-The @code{g77} documentation, in Info format,
-produced by building @code{g77}.
-
-All users of @code{g77} (not just installers) should read this,
-using the @code{more} command if neither the @code{info} command,
-nor GNU Emacs (with its Info mode), are available, or if users
-aren't yet accustomed to using these tools.
-All of these files are readable as ``plain text'' files,
-though they're easier to navigate using Info readers
-such as @code{info} and GNU Emacs Info mode.
-@end table
-
-If you want to explore the FFE code, which lives entirely in @file{f/},
-here are a few clues.
-The file @file{g77spec.c} contains the @code{g77}-specific source code
-for the @code{g77} command only---this just forms a variant of the
-@code{gcc} command, so,
-just as the @code{gcc} command itself does not contain the C front end,
-the @code{g77} command does not contain the Fortran front end (FFE).
-The FFE code ends up in an executable named @file{f771},
-which does the actual compiling,
-so it contains the FFE plus the @code{gcc} back end (GBE),
-the latter to do most of the optimization, and the code generation.
-
-The file @file{parse.c} is the source file for @code{yyparse()},
-which is invoked by the GBE to start the compilation process,
-for @file{f771}.
-
-The file @file{top.c} contains the top-level FFE function @code{ffe_file}
-and it (along with top.h) define all @samp{ffe_[a-z].*}, @samp{ffe[A-Z].*},
-and @samp{FFE_[A-Za-z].*} symbols.
-
-The file @file{fini.c} is a @code{main()} program that is used when building
-the FFE to generate C header and source files for recognizing keywords.
-The files @file{malloc.c} and @file{malloc.h} comprise a memory manager
-that defines all @samp{malloc_[a-z].*}, @samp{malloc[A-Z].*}, and
-@samp{MALLOC_[A-Za-z].*} symbols.
-
-All other modules named @var{xyz}
-are comprised of all files named @samp{@var{xyz}*.@var{ext}}
-and define all @samp{ffe@var{xyz}_[a-z].*}, @samp{ffe@var{xyz}[A-Z].*},
-and @samp{FFE@var{XYZ}_[A-Za-z].*} symbols.
-If you understand all this, congratulations---it's easier for me to remember
-how it works than to type in these regular expressions.
-But it does make it easy to find where a symbol is defined.
-For example, the symbol @samp{ffexyz_set_something} would be defined
-in @file{xyz.h} and implemented there (if it's a macro) or in @file{xyz.c}.
-
-The ``porting'' files of note currently are:
-
-@table @file
-@item proj.h
-This defines the ``language'' used by all the other source files,
-the language being Standard C plus some useful things
-like @code{ARRAY_SIZE} and such.
-
-@item target.c
-@itemx target.h
-These describe the target machine
-in terms of what data types are supported,
-how they are denoted
-(to what C type does an @code{INTEGER*8} map, for example),
-how to convert between them,
-and so on.
-Over time, versions of @code{g77} rely less on this file
-and more on run-time configuration based on GBE info
-in @file{com.c}.
-
-@item com.c
-@itemx com.h
-These are the primary interface to the GBE.
-
-@item ste.c
-@itemx ste.h
-This contains code for implementing recognized executable statements
-in the GBE.
-
-@item src.c
-@itemx src.h
-These contain information on the format(s) of source files
-(such as whether they are never to be processed as case-insensitive
-with regard to Fortran keywords).
-@end table
-
-If you want to debug the @file{f771} executable,
-for example if it crashes,
-note that the global variables @code{lineno} and @code{input_filename}
-are usually set to reflect the current line being read by the lexer
-during the first-pass analysis of a program unit and to reflect
-the current line being processed during the second-pass compilation
-of a program unit.
-
-If an invocation of the function @code{ffestd_exec_end} is on the stack,
-the compiler is in the second pass, otherwise it is in the first.
-
-(This information might help you reduce a test case and/or work around
-a bug in @code{g77} until a fix is available.)
-
-@node Overview of Translation Process
-@section Overview of Translation Process
-
-The order of phases translating source code to the form accepted
-by the GBE is:
-
-@enumerate
-@item
-Stripping punched-card sources (@file{g77stripcard.c})
-
-@item
-Lexing (@file{lex.c})
-
-@item
-Stand-alone statement identification (@file{sta.c})
-
-@item
-INCLUDE handling (@file{sti.c})
-
-@item
-Order-dependent statement identification (@file{stq.c})
-
-@item
-Parsing (@file{stb.c} and @file{expr.c})
-
-@item
-Constructing (@file{stc.c})
-
-@item
-Collecting (@file{std.c})
-
-@item
-Expanding (@file{ste.c})
-@end enumerate
-
-To get a rough idea of how a particularly twisted Fortran statement
-gets treated by the passes, consider:
-
-@smallexample
- FORMAT(I2 4H)=(J/
- & I3)
-@end smallexample
-
-The job of @file{lex.c} is to know enough about Fortran syntax rules
-to break the statement up into distinct lexemes without requiring
-any feedback from subsequent phases:
-
-@smallexample
-`FORMAT'
-`('
-`I24H'
-`)'
-`='
-`('
-`J'
-`/'
-`I3'
-`)'
-@end smallexample
-
-The job of @file{sta.c} is to figure out the kind of statement,
-or, at least, statement form, that sequence of lexemes represent.
-
-The sooner it can do this (in terms of using the smallest number of
-lexemes, starting with the first for each statement), the better,
-because that leaves diagnostics for problems beyond the recognition
-of the statement form to subsequent phases,
-which can usually better describe the nature of the problem.
-
-In this case, the @samp{=} at ``level zero''
-(not nested within parentheses)
-tells @file{sta.c} that this is an @emph{assignment-form},
-not @code{FORMAT}, statement.
-
-An assignment-form statement might be a statement-function
-definition or an executable assignment statement.
-
-To make that determination,
-@file{sta.c} looks at the first two lexemes.
-
-Since the second lexeme is @samp{(},
-the first must represent an array for this to be an assignment statement,
-else it's a statement function.
-
-Either way, @file{sta.c} hands off the statement to @file{stq.c}
-(via @file{sti.c}, which expands INCLUDE files).
-@file{stq.c} figures out what a statement that is,
-on its own, ambiguous, must actually be based on the context
-established by previous statements.
-
-So, @file{stq.c} watches the statement stream for executable statements,
-END statements, and so on, so it knows whether @samp{A(B)=C} is
-(intended as) a statement-function definition or an assignment statement.
-
-After establishing the context-aware statement info, @file{stq.c}
-passes the original sample statement on to @file{stb.c}
-(either its statement-function parser or its assignment-statement parser).
-
-@file{stb.c} forms a
-statement-specific record containing the pertinent information.
-That information includes a source expression and,
-for an assignment statement, a destination expression.
-Expressions are parsed by @file{expr.c}.
-
-This record is passed to @file{stc.c},
-which copes with the implications of the statement
-within the context established by previous statements.
-
-For example, if it's the first statement in the file
-or after an @code{END} statement,
-@file{stc.c} recognizes that, first of all,
-a main program unit is now being lexed
-(and tells that to @file{std.c}
-before telling it about the current statement).
-
-@file{stc.c} attaches whatever information it can,
-usually derived from the context established by the preceding statements,
-and passes the information to @file{std.c}.
-
-@file{std.c} saves this information away,
-since the GBE cannot cope with information
-that might be incomplete at this stage.
-
-For example, @samp{I3} might later be determined
-to be an argument to an alternate @code{ENTRY} point.
-
-When @file{std.c} is told about the end of an external (top-level)
-program unit,
-it passes all the information it has saved away
-on statements in that program unit
-to @file{ste.c}.
-
-@file{ste.c} ``expands'' each statement, in sequence, by
-constructing the appropriate GBE information and calling
-the appropriate GBE routines.
-
-Details on the transformational phases follow.
-Keep in mind that Fortran numbering is used,
-so the first character on a line is column 1,
-decimal numbering is used, and so on.

-@subsection g77stripcard
-
-The @code{g77stripcard} program handles removing content beyond
-column 72 (adjustable via a command-line option),
-optionally warning about that content being something other
-than trailing whitespace or Fortran commentary.
-
-This program is needed because @code{lex.c} doesn't pay attention
-to maximum line lengths at all, to make it easier to maintain,
-as well as faster (for sources that don't depend on the maximum
-column length vis-a-vis trailing non-blank non-commentary content).
-
-Just how this program will be run---whether automatically for
-old source (perhaps as the default for @file{.f} files?)---is not
-yet determined.
-
-In the meantime, it might as well be implemented as a typical UNIX pipe.
-
-It should accept a @samp{-fline-length-@var{n}} option,
-with the default line length set to 72.
-
-When the text it strips off the end of a line is not blank
-(not spaces and tabs),
-it should insert an additional comment line
-(beginning with @samp{!},
-so it works for both fixed-form and free-form files)
-containing the text,
-following the stripped line.
-The inserted comment should have a prefix of some kind,
-TBD, that distinguishes the comment as representing stripped text.
-Users could use that to @code{sed} out such lines, if they wished---it
-seems silly to provide a command-line option to delete information
-when it can be so easily filtered out by another program.
-
-(This inserted comment should be designed to ``fit in'' well
-with whatever the Fortran community is using these days for
-preprocessor, translator, and other such products, like OpenMP.
-What that's all about, and how @code{g77} can elegantly fit its
-special comment conventions into it all, is TBD as well.
-We don't want to reinvent the wheel here, but if there turn out
-to be too many conflicting conventions, we might have to invent
-one that looks nothing like the others, but which offers their
-host products a better infrastructure in which to fit and coexist
-peacefully.)
-
-@code{g77stripcard} probably shouldn't do any tab expansion or other
-fancy stuff.
-People can use @code{expand} or other pre-filtering if they like.
-The idea here is to keep each stage quite simple, while providing
-excellent performance for ``normal'' code.
-
-(Code with junk beyond column 73 is not really ``normal'',
-as it comes from a card-punch heritage,
-and will be increasingly hard for tomorrow's Fortran programmers to read.)
-
-@node lex.c
-@subsection lex.c
-
-To help make the lexer simple, fast, and easy to maintain,
-while also having @code{g77} generally encourage Fortran programmers
-to write simple, maintainable, portable code by maximizing the
-performance of compiling that kind of code:
-
-@itemize @bullet
-@item
-There'll be just one lexer, for both fixed-form and free-form source.
-
-@item
-It'll care about the form only when handling the first 7 columns of
-text, stuff like spaces between strings of alphanumerics, and
-how lines are continued.
-
-Some other distinctions will be handled by subsequent phases,
-so at least one of them will have to know which form is involved.
-
-For example, @samp{I = 2 . 4} is acceptable in fixed form,
-and works in free form as well given the implementation @code{g77}
-presently uses.
-But the standard requires a diagnostic for it in free form,
-so the parser has to be able to recognize that
-the lexemes aren't contiguous
-(information the lexer @emph{does} have to provide)
-and that free-form source is being parsed,
-so it can provide the diagnostic.
-
-The @code{g77} lexer doesn't try to gather @samp{2 . 4} into a single lexeme.
-Otherwise, it'd have to know a whole lot more about how to parse Fortran,
-or subsequent phases (mainly parsing) would have two paths through
-lots of critical code---one to handle the lexeme @samp{2}, @samp{.},
-and @samp{4} in sequence, another to handle the lexeme @samp{2.4}.
-
-@item
-It won't worry about line lengths
-(beyond the first 7 columns for fixed-form source).
-
-That is, once it starts parsing the ``statement'' part of a line
-(column 7 for fixed-form, column 1 for free-form),
-it'll keep going until it finds a newline,
-rather than ignoring everything past a particular column
-(72 or 132).
-
-The implication here is that there shouldn't @emph{be}
-anything past that last column, other than whitespace or
-commentary, because users using typical editors
-(or viewing output as typically printed)
-won't necessarily know just where the last column is.
-
-Code that has ``garbage'' beyond the last column
-(almost certainly only fixed-form code with a punched-card legacy,
-such as code using columns 73-80 for ``sequence numbers'')
-will have to be run through @code{g77stripcard} first.
-
-Also, keeping track of the maximum column position while also watching out
-for the end of a line @emph{and} while reading from a file
-just makes things slower.
-Since a file must be read, and watching for the end of the line
-is necessary (unless the typical input file was preprocessed to
-include the necessary number of trailing spaces),
-dropping the tracking of the maximum column position
-is the only way to reduce the complexity of the pertinent code
-while maintaining high performance.
-
-@item
-ASCII encoding is assumed for the input file.
-
-Code written in other character sets will have to be converted first.
-
-@item
-Tabs (ASCII code 9)
-will be converted to spaces via the straightforward
-approach.
-
-Specifically, a tab is converted to between one and eight spaces
-as necessary to reach column @var{n},
-where dividing @samp{(@var{n} - 1)} by eight
-results in a remainder of zero.
-
-That saves having to pass most source files through @code{expand}.
-
-@item
-Linefeeds (ASCII code 10)
-mark the ends of lines.
-
-@item
-A carriage return (ASCII code 13)
-is accept if it immediately precedes a linefeed,
-in which case it is ignored.
-
-Otherwise, it is rejected (with a diagnostic).
-
-@item
-Any other characters other than the above
-that are not part of the GNU Fortran Character Set
-(@pxref{Character Set})
-are rejected with a diagnostic.
-
-This includes backspaces, form feeds, and the like.
-
-(It might make sense to allow a form feed in column 1
-as long as that's the only character on a line.
-It certainly wouldn't seem to cost much in terms of performance.)
-
-@item
-The end of the input stream (EOF)
-ends the current line.
-
-@item
-The distinction between uppercase and lowercase letters
-will be preserved.
-
-It will be up to subsequent phases to decide to fold case.
-
-Current plans are to permit any casing for Fortran (reserved) keywords
-while preserving casing for user-defined names.
-(This might not be made the default for @file{.f} files, though.)
-
-Preserving case seems necessary to provide more direct access
-to facilities outside of @code{g77}, such as to C or Pascal code.
-
-Names of intrinsics will probably be matchable in any case,
-
-(How @samp{external SiN; r = sin(x)} would be handled is TBD.
-I think old @code{g77} might already handle that pretty elegantly,
-but whether we can cope with allowing the same fragment to reference
-a @emph{different} procedure, even with the same interface,
-via @samp{s = SiN(r)}, needs to be determined.
-If it can't, we need to make sure that when code introduces
-a user-defined name, any intrinsic matching that name
-using a case-insensitive comparison
-is ``turned off''.)
-
-@item
-Backslashes in @code{CHARACTER} and Hollerith constants
-are not allowed.
-
-This avoids the confusion introduced by some Fortran compiler vendors
-providing C-like interpretation of backslashes,
-while others provide straight-through interpretation.
-
-Some kind of lexical construct (TBD) will be provided to allow
-flagging of a @code{CHARACTER}
-(but probably not a Hollerith)
-constant that permits backslashes.
-It'll necessarily be a prefix, such as:
-
-@smallexample
-PRINT *, C'This line has a backspace \b here.'
-PRINT *, F'This line has a straight backslash \ here.'
-@end smallexample
-
-Further, command-line options might be provided to specify that
-one prefix or the other is to be assumed as the default
-for @code{CHARACTER} constants.
-
-However, it seems more helpful for @code{g77} to provide a program
-that converts prefix all constants
-(or just those containing backslashes)
-with the desired designation,
-so printouts of code can be read
-without knowing the compile-time options used when compiling it.
-
-If such a program is provided
-(let's name it @code{g77slash} for now),
-then a command-line option to @code{g77} should not be provided.
-(Though, given that it'll be easy to implement, it might be hard
-to resist user requests for it ``to compile faster than if we
-have to invoke another filter''.)
-
-This program would take a command-line option to specify the
-default interpretation of slashes,
-affecting which prefix it uses for constants.
-
-@code{g77slash} probably should automatically convert Hollerith
-constants that contain slashes
-to the appropriate @code{CHARACTER} constants.
-Then @code{g77} wouldn't have to define a prefix syntax for Hollerith
-constants specifying whether they want C-style or straight-through
-backslashes.
-
-@item
-To allow for form-neutral INCLUDE files without requiring them
-to be preprocessed,
-the fixed-form lexer should offer an extension (if possible)
-allowing a trailing @samp{&} to be ignored, especially if after
-column 72, as it would be using the traditional Unix Fortran source
-model (which ignores @emph{everything} after column 72).
-@end itemize
-
-The above implements nearly exactly what is specified by
-@ref{Character Set},
-and
-@ref{Lines},
-except it also provides automatic conversion of tabs
-and ignoring of newline-related carriage returns,
-as well as accommodating form-neutral INCLUDE files.
-
-It also implements the ``pure visual'' model,
-by which is meant that a user viewing his code
-in a typical text editor
-(assuming it's not preprocessed via @code{g77stripcard} or similar)
-doesn't need any special knowledge
-of whether spaces on the screen are really tabs,
-whether lines end immediately after the last visible non-space character
-or after a number of spaces and tabs that follow it,
-or whether the last line in the file is ended by a newline.
-
-Most editors don't make these distinctions,
-the ANSI FORTRAN 77 standard doesn't require them to,
-and it permits a standard-conforming compiler
-to define a method for transforming source code to
-``standard form'' however it wants.
-
-So, GNU Fortran defines it such that users have the best chance
-of having the code be interpreted the way it looks on the screen
-of the typical editor.
-
-(Fancy editors should @emph{never} be required to correctly read code
-written in classic two-dimensional-plaintext form.
-By correct reading I mean ability to read it, book-like, without
-mistaking text ignored by the compiler for program code and vice versa,
-and without having to count beyond the first several columns.
-The vague meaning of ASCII TAB, among other things, complicates
-this somewhat, but as long as ``everyone'', including the editor,
-other tools, and printer, agrees about the every-eighth-column convention,
-the GNU Fortran ``pure visual'' model meets these requirements.
-Any language or user-visible source form
-requiring special tagging of tabs,
-the ends of lines after spaces/tabs,
-and so on, fails to meet this fairly straightforward specification.
-Fortunately, Fortran @emph{itself} does not mandate such a failure,
-though most vendor-supplied defaults for their Fortran compilers @emph{do}
-fail to meet this specification for readability.)
-
-Further, this model provides a clean interface
-to whatever preprocessors or code-generators are used
-to produce input to this phase of @code{g77}.
-Mainly, they need not worry about long lines.

-@subsection Gotchas (Transforming)
-
-This section is not about transforming ``gotchas'' into something else.
-It is about the weirder aspects of transforming Fortran,
-however that's defined,
-into a more modern, canonical form.
-
-@subsubsection Multi-character Lexemes
-
-Each lexeme carries with it a pointer to where it appears in the source.
-
-To provide the ability for diagnostics to point to column numbers,
-in addition to line numbers and names,
-lexemes that represent more than one (significant) character
-in the source code need, generally,
-to provide pointers to where each @emph{character} appears in the source.
-
-This provides the ability to properly identify the precise location
-of the problem in code like
-
-@smallexample
-SUBROUTINE X
-END
-BLOCK DATA X
-END
-@end smallexample
-
-which, in fixed-form source, would result in single lexemes
-consisting of the strings @samp{SUBROUTINEX} and @samp{BLOCKDATAX}.
-(The problem is that @samp{X} is defined twice,
-so a pointer to the @samp{X} in the second definition,
-as well as a follow-up pointer to the corresponding pointer in the first,
-would be preferable to pointing to the beginnings of the statements.)
-
-This need also arises when parsing (and diagnosing) @code{FORMAT}
-statements.
-
-Further, it arises when diagnosing
-@code{FMT=} specifiers that contain constants
-(or partial constants, or even propagated constants!)
-in I/O statements, as in:
-
-@smallexample
-PRINT '(I2, 3HAB)', J
-@end smallexample
-
-(A pointer to the beginning of the prematurely-terminated Hollerith
-constant, and/or to the close parenthese, is preferable to a pointer
-to the open-parenthese or the apostrophe that precedes it.)
-
-Multi-character lexemes, which would seem to naturally include
-at least digit strings, alphanumeric strings, @code{CHARACTER}
-constants, and Hollerith constants, therefore need to provide
-location information on each character.
-(Maybe Hollerith constants don't, but it's unnecessary to except them.)
-
-The question then arises, what about @emph{other} multi-character lexemes,
-such as @samp{**} and @samp{//},
-and Fortran 90's @samp{(/}, @samp{/)}, @samp{::}, and so on?
-
-Turns out there's a need to identify the location of the second character
-of these two-character lexemes.
-For example, in @samp{I(/J) = K}, the slash needs to be diagnosed
-as the problem, not the open parenthese.
-Similarly, it is preferable to diagnose the second slash in
-@samp{I = J // K} rather than the first, given the implicit typing
-rules, which would result in the compiler disallowing the attempted
-concatenation of two integers.
-(Though, since that's more of a semantic issue,
-it's not @emph{that} much preferable.)
-
-Even sequences that could be parsed as digit strings could use location info,
-for example, to diagnose the @samp{9} in the octal constant @samp{O'129'}.
-(This probably will be parsed as a character string,
-to be consistent with the parsing of @samp{Z'129A'}.)
-
-To avoid the hassle of recording the location of the second character,
-while also preserving the general rule that each significant character
-is distinctly pointed to by the lexeme that contains it,
-it's best to simply not have any fixed-size lexemes
-larger than one character.
-
-This new design is expected to make checking for two
-@samp{*} lexemes in a row much easier than the old design,
-so this is not much of a sacrifice.
-It probably makes the lexer much easier to implement
-than it makes the parser harder.
-
-@subsubsection Space-padding Lexemes
-
-Certain lexemes need to be padded with virtual spaces when the
-end of the line (or file) is encountered.
-
-This is necessary in fixed form, to handle lines that don't
-extend to column 72, assuming that's the line length in effect.
-
-@subsubsection Bizarre Free-form Hollerith Constants
-
-Last I checked, the Fortran 90 standard actually required the compiler
-to silently accept something like
-
-@smallexample
-FORMAT ( 1 2 Htwelve chars )
-@end smallexample
-
-as a valid @code{FORMAT} statement specifying a twelve-character
-Hollerith constant.
-
-The implication here is that, since the new lexer is a zero-feedback one,
-it won't know that the special case of a @code{FORMAT} statement being parsed
-requires apparently distinct lexemes @samp{1} and @samp{2} to be treated as
-a single lexeme.
-
-(This is a horrible misfeature of the Fortran 90 language.
-It's one of many such misfeatures that almost make me want
-to not support them, and forge ahead with designing a new
-``GNU Fortran'' language that has the features,
-but not the misfeatures, of Fortran 90,
-and provide utility programs to do the conversion automatically.)
-
-So, the lexer must gather distinct chunks of decimal strings into
-a single lexeme in contexts where a single decimal lexeme might
-start a Hollerith constant.
-
-(Which probably means it might as well do that all the time
-for all multi-character lexemes, even in free-form mode,
-leaving it to subsequent phases to pull them apart as they see fit.)
-
-Compare the treatment of this to how
-
-@smallexample
-CHARACTER * 4 5 HEY
-@end smallexample
-
-and
-
-@smallexample
-CHARACTER * 12 HEY
-@end smallexample
-
-must be treated---the former must be diagnosed, due to the separation
-between lexemes, the latter must be accepted as a proper declaration.
-
-@subsubsection Hollerith Constants
-
-Recognizing a Hollerith constant---specifically,
-that an @samp{H} or @samp{h} after a digit string begins
-such a constant---requires some knowledge of context.
-
-Hollerith constants (such as @samp{2HAB}) can appear after:
-
-@itemize @bullet
-@item
-@samp{(}
-
-@item
-@samp{,}
-
-@item
-@samp{=}
-
-@item
-@samp{+}, @samp{-}, @samp{/}
-
-@item
-@samp{*}, except as noted below
-@end itemize
-
-Hollerith constants don't appear after:
-
-@itemize @bullet
-@item
-@samp{CHARACTER*},
-which can be treated generally as
-any @samp{*} that is the second lexeme of a statement
-@end itemize
-
-@subsubsection Confusing Function Keyword
-
-While
-
-@smallexample
-REAL FUNCTION FOO ()
-@end smallexample
-
-must be a @code{FUNCTION} statement and
-
-@smallexample
-REAL FUNCTION FOO (5)
-@end smallexample
-
-must be a type-definition statement,
-
-@smallexample
-REAL FUNCTION FOO (@var{names})
-@end smallexample
-
-where @var{names} is a comma-separated list of names,
-can be one or the other.
-
-The only way to disambiguate that statement
-(short of mandating free-form source or a short maximum
-length for name for external procedures)
-is based on the context of the statement.
-
-In particular, the statement is known to be within an
-already-started program unit
-(but not at the outer level of the @code{CONTAINS} block),
-it is a type-declaration statement.
-
-Otherwise, the statement is a @code{FUNCTION} statement,
-in that it begins a function program unit
-(external, or, within @code{CONTAINS}, nested).
-
-@subsubsection Weird READ
-
-The statement
-
-@smallexample
-READ (N)
-@end smallexample
-
-is equivalent to either
-
-@smallexample
-READ (UNIT=(N))
-@end smallexample
-
-or
-
-@smallexample
-READ (FMT=(N))
-@end smallexample
-
-depending on which would be valid in context.
-
-Specifically, if @samp{N} is type @code{INTEGER},
-@samp{READ (FMT=(N))} would not be valid,
-because parentheses may not be used around @samp{N},
-whereas they may around it in @samp{READ (UNIT=(N))}.
-
-Further, if @samp{N} is type @code{CHARACTER},
-the opposite is true---@samp{READ (UNIT=(N))} is not valid,
-but @samp{READ (FMT=(N))} is.
-
-Strictly speaking, if anything follows
-
-@smallexample
-READ (N)
-@end smallexample
-
-in the statement, whether the first lexeme after the close
-parenthese is a comma could be used to disambiguate the two cases,
-without looking at the type of @samp{N},
-because the comma is required for the @samp{READ (FMT=(N))}
-interpretation and disallowed for the @samp{READ (UNIT=(N))}
-interpretation.
-
-However, in practice, many Fortran compilers allow
-the comma for the @samp{READ (UNIT=(N))}
-interpretation anyway
-(in that they generally allow a leading comma before
-an I/O list in an I/O statement),
-and much code takes advantage of this allowance.
-
-(This is quite a reasonable allowance, since the
-juxtaposition of a comma-separated list immediately
-after an I/O control-specification list, which is also comma-separated,
-without an intervening comma,
-looks sufficiently ``wrong'' to programmers
-that they can't resist the itch to insert the comma.
-@samp{READ (I, J), K, L} simply looks cleaner than
-@samp{READ (I, J) K, L}.)
-
-So, type-based disambiguation is needed unless strict adherence
-to the standard is always assumed, and we're not going to assume that.

-Continue researching gotchas, designing the transformational process,
-and implementing it.
-
-Specific issues to resolve:
-
-@itemize @bullet
-@item
-Just where should (if it was implemented) @code{USE} processing take place?
-
-This gets into the whole issue of how @code{g77} should handle the concept
-of modules.
-I think GNAT already takes on this issue, but don't know more than that.
-Jim Giles has written extensively on @code{comp.lang.fortran}
-about his opinions on module handling, as have others.
-Jim's views should be taken into account.
-
-Actually, Richard M. Stallman (RMS) also has written up
-some guidelines for implementing such things,
-but I'm not sure where I read them.
-Perhaps the old @email{gcc2@@cygnus.com} list.
-
-If someone could dig references to these up and get them to me,
-that would be much appreciated!
-Even though modules are not on the short-term list for implementation,
-it'd be helpful to know @emph{now} how to avoid making them harder to
-implement them @emph{later}.
-
-@item
-Should the @code{g77} command become just a script that invokes
-all the various preprocessing that might be needed,
-thus making it seem slower than necessary for legacy code
-that people are unwilling to convert,
-or should we provide a separate script for that,
-thus encouraging people to convert their code once and for all?
-
-At least, a separate script to behave as old @code{g77} did,
-perhaps named @code{g77old}, might ease the transition,
-as might a corresponding one that converts source codes
-named @code{g77oldnew}.
-
-These scripts would take all the pertinent options @code{g77} used
-to take and run the appropriate filters,
-passing the results to @code{g77} or just making new sources out of them
-(in a subdirectory, leaving the user to do the dirty deed of
-moving or copying them over the old sources).
-
-@item
-Do other Fortran compilers provide a prefix syntax
-to govern the treatment of backslashes in @code{CHARACTER}
-(or Hollerith) constants?
-
-Knowing what other compilers provide would help.

-Is it okay to drop support for the @samp{-fintrin-case-initcap},
-@samp{-fmatch-case-initcap}, @samp{-fsymbol-case-initcap},
-and @samp{-fcase-initcap} options?
-
-I've asked @email{info-gnu-fortran@@gnu.org} for input on this.
-Not having to support these makes it easier to write the new front end,
-and might also avoid complicated its design.
-
-The consensus to date (1999-11-17) has been to drop this support.

-@cindex GNU Back End (GBE)
-@cindex GBE
-@cindex @code{gcc}, back end
-@cindex back end, gcc
-@cindex code generator
-The @code{gcc} back end (GBE) is a large, complex
-labyrinth of intricate code
-written in a combination of the C language
-and specialized languages internal to @code{gcc}.
-
-While the @emph{code} that implements the GBE
-is written in a combination of languages,
-the GBE itself is,
-to the front end for a language like Fortran,
-best viewed as a @emph{compiler}
-that compiles its own, unique, language.
-
-The GBE's ``source'', then, is written in this language,
-which consists primarily of
-a combination of calls to GBE functions
-and @dfn{tree} nodes
-(which are, themselves, created
-by calling GBE functions).
-
-So, the @code{g77} generates code by, in effect,
-translating the Fortran code it reads
-into a form ``written'' in the ``language''
-of the @code{gcc} back end.
-
-@cindex GBEL
-@cindex GNU Back End Language (GBEL)
-This language will heretofore be referred to as @dfn{GBEL},

-It offers many facilities,

-are those that corresponding most directly
-to those needed to support @code{gcc}
-(compiling code written in GNU C).
-
-The @code{g77} Fortran Front End (FFE)
-is designed and implemented
-to navigate the currents and eddies
-of ongoing GBEL and @code{gcc} development
-while also delivering on the potential
-of an integrated FFE
-(as compared to using a converter like @code{f2c}
-and feeding the output into @code{gcc}).
-
-Goals of the FFE's code-generation strategy include:
-
-@itemize @bullet
-@item
-High likelihood of generation of correct code,
-or, failing that, producing a fatal diagnostic or crashing.
-
-@item
-Generation of highly optimized code,
-as directed by the user

-such as command-line options.
-
-@item
-Fast overall (FFE plus GBE) compilation.
-
-@item
-Preservation of source-level debugging information.
-@end itemize
-
-The strategies historically, and currently, used by the FFE

-
-@itemize @bullet
-@item
-Use of GBEL constructs that most faithfully encapsulate
-the semantics of Fortran.
-
-@item
-Avoidance of GBEL constructs that are so rarely used,
-or limited to use in specialized situations not related to Fortran,
-that their reliability and performance has not yet been established
-as sufficient for use by the FFE.
-
-@item
-Flexible design, to readily accommodate changes to specific
-code-generation strategies, perhaps governed by command-line options.
-@end itemize
-
-@cindex Bear-poking
-@cindex Poking the bear
-``Don't poke the bear'' somewhat summarizes the above strategies.
-The GBE is the bear.
-The FFE is designed and implemented to avoid poking it
-in ways that are likely to just annoy it.
-The FFE usually either tackles it head-on,
-or avoids treating it in ways dissimilar to how
-the @code{gcc} front end treats it.
-
-For example, the FFE uses the native array facility in the back end
-instead of the lower-level pointer-arithmetic facility
-used by @code{gcc} when compiling @code{f2c} output).
-Theoretically, this presents more opportunities for optimization,
-faster compile times,
-and the production of more faithful debugging information.
-These benefits were not, however, immediately realized,
-mainly because @code{gcc} itself makes little or no use
-of the native array facility.
-
-Complex arithmetic is a case study of the evolution of this strategy.
-When originally implemented,
-the GBEL had just evolved its own native complex-arithmetic facility,
-so the FFE took advantage of that.
-
-When porting @code{g77} to 64-bit systems,
-it was discovered that the GBE didn't really
-implement its native complex-arithmetic facility properly.
-
-The short-term solution was to rewrite the FFE
-to instead use the lower-level facilities
-that'd be used by @code{gcc}-compiled code
-(assuming that code, itself, didn't use the native complex type
-provided, as an extension, by @code{gcc}),
-since these were known to work,
-and, in any case, if shown to not work,
-would likely be rapidly fixed
-(since they'd likely not work for vanilla C code in similar circumstances).
-
-However, the rewrite accommodated the original, native approach as well
-by offering a command-line option to select it over the emulated approach.
-This allowed users, and especially GBE maintainers, to try out
-fixes to complex-arithmetic support in the GBE
-while @code{g77} continued to default to compiling more code correctly,
-albeit producing (typically) slower executables.
-
-As of April 1999, it appeared that the last few bugs
-in the GBE's support of its native complex-arithmetic facility
-were worked out.
-The FFE was changed back to default to using that native facility,
-leaving emulation as an option.
-
-Later during the release cycle
-(which was called EGCS 1.2, but soon became GCC 2.95),
-bugs in the native facility were found.
-Reactions among various people included
-``the last thing we should do is change the default back'',
-``we must change the default back'',
-and ``let's figure out whether we can narrow down the bugs to
-few enough cases to allow the now-months-long-tested default
-to remain the same''.
-The latter viewpoint won that particular time.
-The bugs exposed other concerns regarding ABI compliance
-when the ABI specified treatment of complex data as different
-from treatment of what Fortran and GNU C consider the equivalent
-aggregation (structure) of real (or float) pairs.
-
-Other Fortran constructs---arrays, character strings,
-complex division, @code{COMMON} and @code{EQUIVALENCE} aggregates,
-and so on---involve issues similar to those pertaining to complex arithmetic.
-
-So, it is possible that the history
-of how the FFE handled complex arithmetic
-will be repeated, probably in modified form
-(and hopefully over shorter timeframes),
-for some of these other facilities.
-
-@node Two-pass Design
-@section Two-pass Design
-
-The FFE does not tell the GBE anything about a program unit
-until after the last statement in that unit has been parsed.
-(A program unit is a Fortran concept that corresponds, in the C world,
-mostly closely to functions definitions in ISO C.
-That is, a program unit in Fortran is like a top-level function in C.
-Nested functions, found among the extensions offered by GNU C,
-correspond roughly to Fortran's statement functions.)
-
-So, while parsing the code in a program unit,
-the FFE saves up all the information
-on statements, expressions, names, and so on,
-until it has seen the last statement.
-
-At that point, the FFE revisits the saved information
-(in what amounts to a second @dfn{pass} over the program unit)
-to perform the actual translation of the program unit into GBEL,
-ultimating in the generation of assembly code for it.
-
-Some lookahead is performed during this second pass,
-so the FFE could be viewed as a ``two-plus-pass'' design.

-@node Two-pass Code
-@subsection Two-pass Code
-
-Most of the code that turns the first pass (parsing)
-into a second pass for code generation
-is in @file{@value{path-g77}/std.c}.
-
-It has external functions,
-called mainly by siblings in @file{@value{path-g77}/stc.c},
-that record the information on statements and expressions
-in the order they are seen in the source code.
-These functions save that information.
-
-It also has an external function that revisits that information,
-calling the siblings in @file{@value{path-g77}/ste.c},
-which handles the actual code generation
-(by generating GBEL code,
-that is, by calling GBE routines
-to represent and specify expressions, statements, and so on).
-
-@node Why Two Passes
-@subsection Why Two Passes
-
-The need for two passes was not immediately evident
-during the design and implementation of the code in the FFE
-that was to produce GBEL.
-Only after a few kludges,
-to handle things like incorrectly-guessed @code{ASSIGN} label nature,
-had been implemented,
-did enough evidence pile up to make it clear
-that @file{std.c} had to be introduced to intercept,
-save, then revisit as part of a second pass,
-the digested contents of a program unit.
-
-Other such missteps have occurred during the evolution of the FFE,
-because of the different goals of the FFE and the GBE.
-
-Because the GBE's original, and still primary, goal
-was to directly support the GNU C language,
-the GBEL, and the GBE itself,
-requires more complexity
-on the part of most front ends
-than it requires of @code{gcc}'s.
-
-For example,
-the GBEL offers an interface that permits the @code{gcc} front end
-to implement most, or all, of the language features it supports,
-without the front end having to
-make use of non-user-defined variables.
-(It's almost certainly the case that all of K&R C,
-and probably ANSI C as well,
-is handled by the @code{gcc} front end
-without declaring such variables.)
-
-The FFE, on the other hand, must resort to a variety of ``tricks''
-to achieve its goals.
-
-Consider the following C code:
-
-@smallexample
-int
-foo (int a, int b)
-@{
- int c = 0;
-
- if ((c = bar (c)) == 0)
- goto done;
-
- quux (c << 1);
-
-done:
- return c;
-@}
-@end smallexample
-
-Note what kinds of objects are declared, or defined, before their use,
-and before any actual code generation involving them
-would normally take place:
-
-@itemize @bullet
-@item
-Return type of function
-
-@item
-Entry point(s) of function
-
-@item
-Dummy arguments
-

-@end itemize

-suddenly appear ``out of the blue'' in C:
-
-@itemize @bullet
-@item
-Label references
-
-@item
-Function references
-@end itemize
-
-Not surprisingly, the GBE faithfully permits the latter set of items
-to be ``discovered'' partway through GBEL ``programs'',
-just as they are permitted to in C.
-
-Yet, the GBE has tended, at least in the past,
-to be reticent to fully support similar ``late'' discovery
-of items in the former set.
-
-This makes Fortran a poor fit for the ``safe'' subset of GBEL.
-Consider:
-
-@smallexample
- FUNCTION X (A, ARRAY, ID1)
- CHARACTER*(*) A
- DOUBLE PRECISION X, Y, Z, TMP, EE, PI
- REAL ARRAY(ID1*ID2)
- COMMON ID2

- ASSIGN 100 TO J
- CALL FOO (I)
- IF (I .EQ. 0) PRINT *, A(0)
- GOTO 200
-
- ENTRY Y (Z)
- ASSIGN 101 TO J
-200 PRINT *, A(1)
- READ *, TMP
- GOTO J
-100 X = TMP * EE
- RETURN
-101 Y = TMP * PI
- CALL FRED
- DATA EE, PI /2.71D0, 3.14D0/

-@end smallexample
-
-Here are some observations about the above code,
-which, while somewhat contrived,
-conforms to the FORTRAN 77 and Fortran 90 standards:
-
-@itemize @bullet
-@item
-The return type of function @samp{X} is not known
-until the @samp{DOUBLE PRECISION} line has been parsed.
-
-@item
-Whether @samp{A} is a function or a variable
-is not known until the @samp{PRINT *, A(0)} statement
-has been parsed.
-
-@item
-The bounds of the array of argument @samp{ARRAY}
-depend on a computation involving
-the subsequent argument @samp{ID1}
-and the blank-common member @samp{ID2}.
-
-@item
-Whether @samp{Y} and @samp{Z} are local variables,
-additional function entry points,
-or dummy arguments to additional entry points
-is not known
-until the @code{ENTRY} statement is parsed.
-
-@item
-Similarly, whether @samp{TMP} is a local variable is not known
-until the @samp{READ *, TMP} statement is parsed.
-
-@item
-The initial values for @samp{EE} and @samp{PI}
-are not known until after the @code{DATA} statement is parsed.
-
-@item
-Whether @samp{FRED} is a function returning type @code{REAL}
-or a subroutine
-(which can be thought of as returning type @code{void}
-@emph{or}, to support alternate returns in a simple way,
-type @code{int})
-is not known
-until the @samp{CALL FRED} statement is parsed.
-
-@item
-Whether @samp{100} is a @code{FORMAT} label
-or the label of an executable statement
-is not known
-until the @samp{X =} statement is parsed.
-(These two types of labels get @emph{very} different treatment,
-especially when @code{ASSIGN}'ed.)
-
-@item
-That @samp{J} is a local variable is not known
-until the first @code{ASSIGN} statement is parsed.
-(This happens @emph{after} executable code has been seen.)
-@end itemize
-
-Very few of these ``discoveries''
-can be accommodated by the GBE as it has evolved over the years.
-The GBEL doesn't support several of them,
-and those it might appear to support
-don't always work properly,
-especially in combination with other GBEL and GBE features,
-as implemented in the GBE.
-
-(Had the GBE and its GBEL originally evolved to support @code{g77},
-the shoe would be on the other foot, so to speak---most, if not all,
-of the above would be directly supported by the GBEL,
-and a few C constructs would probably not, as they are in reality,
-be supported.
-Both this mythical, and today's real, GBE caters to its GBEL
-by, sometimes, scrambling around, cleaning up after itself---after
-discovering that assumptions it made earlier during code generation
-are incorrect.
-That's not a great design, since it indicates significant code
-paths that might be rarely tested but used in some key production
-environments.)
-
-So, the FFE handles these discrepancies---between the order in which
-it discovers facts about the code it is compiling,
-and the order in which the GBEL and GBE support such discoveries---by
-performing what amounts to two
-passes over each program unit.
-
-(A few ambiguities can remain at that point,
-such as whether, given @samp{EXTERNAL BAZ}
-and no other reference to @samp{BAZ} in the program unit,
-it is a subroutine, a function, or a block-data---which, in C-speak,
-governs its declared return type.
-Fortunately, these distinctions are easily finessed
-for the procedure, library, and object-file interfaces
-supported by @code{g77}.)
-
-@node Challenges Posed
-@section Challenges Posed
-
-Consider the following Fortran code, which uses various extensions
-(including some to Fortran 90):
-
-@smallexample
-SUBROUTINE X(A)
-CHARACTER*(*) A
-COMPLEX CFUNC
-INTEGER*2 CLOCKS(200)
-INTEGER IFUNC
-
-CALL SYSTEM_CLOCK (CLOCKS (IFUNC (CFUNC ('('//A//')'))))
-@end smallexample
-
-The above poses the following challenges to any Fortran compiler
-that uses run-time interfaces, and a run-time library, roughly similar
-to those used by @code{g77}:
-
-@itemize @bullet
-@item
-Assuming the library routine that supports @code{SYSTEM_CLOCK}
-expects to set an @code{INTEGER*4} variable via its @code{COUNT} argument,
-the compiler must make available to it a temporary variable of that type.
-
-@item
-Further, after the @code{SYSTEM_CLOCK} library routine returns,
-the compiler must ensure that the temporary variable it wrote
-is copied into the appropriate element of the @samp{CLOCKS} array.
-(This assumes the compiler doesn't just reject the code,
-which it should if it is compiling under some kind of a ``strict'' option.)
-
-@item
-To determine the correct index into the @samp{CLOCKS} array,
-(putting aside the fact that the index, in this particular case,
-need not be computed until after
-the @code{SYSTEM_CLOCK} library routine returns),
-the compiler must ensure that the @code{IFUNC} function is called.
-
-That requires evaluating its argument,
-which requires, for @code{g77}
-(assuming @code{-ff2c} is in force),
-reserving a temporary variable of type @code{COMPLEX}
-for use as a repository for the return value
-being computed by @samp{CFUNC}.
-
-@item
-Before invoking @samp{CFUNC},
-is argument must be evaluated,
-which requires allocating, at run time,
-a temporary large enough to hold the result of the concatenation,
-as well as actually performing the concatenation.
-
-@item
-The large temporary needed during invocation of @code{CFUNC}
-should, ideally, be deallocated
-(or, at least, left to the GBE to dispose of, as it sees fit)
-as soon as @code{CFUNC} returns,
-which means before @code{IFUNC} is called
-(as it might need a lot of dynamically allocated memory).
-@end itemize
-
-@code{g77} currently doesn't support all of the above,
-but, so that it might someday, it has evolved to handle
-at least some of the above requirements.
-
-Meeting the above requirements is made more challenging
-by conforming to the requirements of the GBEL/GBE combination.

-@node Transforming Statements
-@section Transforming Statements
-
-Most Fortran statements are given their own block,
-and, for temporary variables they might need, their own scope.
-(A block is what distinguishes @samp{@{ foo (); @}}
-from just @samp{foo ();} in C.
-A scope is included with every such block,
-providing a distinct name space for local variables.)
-
-Label definitions for the statement precede this block,
-so @samp{10 PRINT *, I} is handled more like
-@samp{fl10: @{ @dots{} @}} than @samp{@{ fl10: @dots{} @}}
-(where @samp{fl10} is just a notation meaning ``Fortran Label 10''
-for the purposes of this document).

-@node Statements Needing Temporaries
-@subsection Statements Needing Temporaries
-
-Any temporaries needed during, but not beyond,
-execution of a Fortran statement,
-are made local to the scope of that statement's block.
-
-This allows the GBE to share storage for these temporaries
-among the various statements without the FFE
-having to manage that itself.
-
-(The GBE could, of course, decide to optimize
-management of these temporaries.
-For example, it could, theoretically,
-schedule some of the computations involving these temporaries
-to occur in parallel.
-More practically, it might leave the storage for some temporaries
-``live'' beyond their scopes, to reduce the number of
-manipulations of the stack pointer at run time.)
-
-Temporaries needed across distinct statement boundaries usually
-are associated with Fortran blocks (such as @code{DO}/@code{END DO}).
-(Also, there might be temporaries not associated with blocks at all---these
-would be in the scope of the entire program unit.)
-
-Each Fortran block @emph{should} get its own block/scope in the GBE.
-This is best, because it allows temporaries to be more naturally handled.
-However, it might pose problems when handling labels
-(in particular, when they're the targets of @code{GOTO}s outside the Fortran
-block), and generally just hassling with replicating
-parts of the @code{gcc} front end
-(because the FFE needs to support
-an arbitrary number of nested back-end blocks
-if each Fortran block gets one).
-
-So, there might still be a need for top-level temporaries, whose
-``owning'' scope is that of the containing procedure.
-
-Also, there seems to be problems declaring new variables after
-generating code (within a block) in the back end, leading to, e.g.,
-@samp{label not defined before binding contour} or similar messages,
-when compiling with @samp{-fstack-check} or
-when compiling for certain targets.
-
-Because of that, and because sometimes these temporaries are not
-discovered until in the middle of of generating code for an expression
-statement (as in the case of the optimization for @samp{X**I}),
-it seems best to always
-pre-scan all the expressions that'll be expanded for a block
-before generating any of the code for that block.
-
-This pre-scan then handles discovering and declaring, to the back end,
-the temporaries needed for that block.
-
-It's also important to treat distinct items in an I/O list as distinct
-statements deserving their own blocks.
-That's because there's a requirement
-that each I/O item be fully processed before the next one,
-which matters in cases like @samp{READ (*,*), I, A(I)}---the
-element of @samp{A} read in the second item
-@emph{must} be determined from the value
-of @samp{I} read in the first item.
-
-@node Transforming DO WHILE
-@subsection Transforming DO WHILE
-
-@samp{DO WHILE(expr)} @emph{must} be implemented
-so that temporaries needed to evaluate @samp{expr}
-are generated just for the test, each time.
-
-Consider how @samp{DO WHILE (A//B .NE. 'END'); @dots{}; END DO} is transformed:
-
-@smallexample
-for (;;)
- @{
- int temp0;
-
- @{
- char temp1[large];
-
- libg77_catenate (temp1, a, b);
- temp0 = libg77_ne (temp1, 'END');
- @}
-
- if (! temp0)
- break;
-
- @dots{}
- @}
-@end smallexample
-
-In this case, it seems like a time/space tradeoff
-between allocating and deallocating @samp{temp1} for each iteration
-and allocating it just once for the entire loop.
-
-However, if @samp{temp1} is allocated just once for the entire loop,
-it could be the wrong size for subsequent iterations of that loop
-in cases like @samp{DO WHILE (A(I:J)//B .NE. 'END')},
-because the body of the loop might modify @samp{I} or @samp{J}.
-
-So, the above implementation is used,
-though a more optimal one can be used
-in specific circumstances.
-
-@node Transforming Iterative DO
-@subsection Transforming Iterative DO
-
-An iterative @code{DO} loop
-(one that specifies an iteration variable)
-is required by the Fortran standards
-to be implemented as though an iteration count
-is computed before entering the loop body,
-and that iteration count used to determine
-the number of times the loop body is to be performed
-(assuming the loop isn't cut short via @code{GOTO} or @code{EXIT}).
-
-The FFE handles this by allocating a temporary variable
-to contain the computed number of iterations.
-Since this variable must be in a scope that includes the entire loop,
-a GBEL block is created for that loop,
-and the variable declared as belonging to the scope of that block.
-
-@node Transforming Block IF
-@subsection Transforming Block IF
-
-Consider:
-
-@smallexample
-SUBROUTINE X(A,B,C)
-CHARACTER*(*) A, B, C
-LOGICAL LFUNC
-
-IF (LFUNC (A//B)) THEN
- CALL SUBR1
-ELSE IF (LFUNC (A//C)) THEN
- CALL SUBR2
-ELSE
- CALL SUBR3
-END
-@end smallexample
-
-The arguments to the two calls to @samp{LFUNC}
-require dynamic allocation (at run time),
-but are not required during execution of the @code{CALL} statements.
-
-So, the scopes of those temporaries must be within blocks inside
-the block corresponding to the Fortran @code{IF} block.
-
-This cannot be represented ``naturally''
-in vanilla C, nor in GBEL.
-The @code{if}, @code{elseif}, @code{else},
-and @code{endif} constructs
-provided by both languages must,
-for a given @code{if} block,
-share the same C/GBE block.
-
-Therefore, any temporaries needed during evaluation of @samp{expr}
-while executing @samp{ELSE IF(expr)}
-must either have been predeclared
-at the top of the corresponding @code{IF} block,
-or declared within a new block for that @code{ELSE IF}---a block that,
-since it cannot contain the @code{else} or @code{else if} itself
-(due to the above requirement),
-actually implements the rest of the @code{IF} block's
-@code{ELSE IF} and @code{ELSE} statements
-within an inner block.
-
-The FFE takes the latter approach.
-
-@node Transforming SELECT CASE
-@subsection Transforming SELECT CASE
-
-@code{SELECT CASE} poses a few interesting problems for code generation,
-if efficiency and frugal stack management are important.
-
-Consider @samp{SELECT CASE (I('PREFIX'//A))},
-where @samp{A} is @code{CHARACTER*(*)}.
-In a case like this---basically,
-in any case where largish temporaries are needed
-to evaluate the expression---those temporaries should
-not be ``live'' during execution of any of the @code{CASE} blocks.
-
-So, evaluation of the expression is best done within its own block,
-which in turn is within the @code{SELECT CASE} block itself
-(which contains the code for the CASE blocks as well,
-though each within their own block).
-
-Otherwise, we'd have the rough equivalent of this pseudo-code:
-
-@smallexample
-@{
- char temp[large];
-
- libg77_catenate (temp, 'prefix', a);
-
- switch (i (temp))
- @{
- case 0:
- @dots{}
- @}
-@}
-@end smallexample
-
-And that would leave temp[large] in scope during the CASE blocks
-(although a clever back end *could* see that it isn't referenced
-in them, and thus free that temp before executing the blocks).
-
-So this approach is used instead:
-
-@smallexample
-@{
- int temp0;
-
- @{
- char temp1[large];
-
- libg77_catenate (temp1, 'prefix', a);
- temp0 = i (temp1);
- @}
-
- switch (temp0)
- @{
- case 0:
- @dots{}
- @}
-@}
-@end smallexample
-
-Note how @samp{temp1} goes out of scope before starting the switch,
-thus making it easy for a back end to free it.
-
-The problem @emph{that} solution has, however,
-is with @samp{SELECT CASE('prefix'//A)}
-(which is currently not supported).
-
-Unless the GBEL is extended to support arbitrarily long character strings
-in its @code{case} facility,
-the FFE has to implement @code{SELECT CASE} on @code{CHARACTER}
-(probably excepting @code{CHARACTER*1})
-using a cascade of
-@code{if}, @code{elseif}, @code{else}, and @code{endif} constructs
-in GBEL.
-
-To prevent the (potentially large) temporary,
-needed to hold the selected expression itself (@samp{'prefix'//A}),
-from being in scope during execution of the @code{CASE} blocks,
-two approaches are available:
-
-@itemize @bullet
-@item
-Pre-evaluate all the @code{CASE} tests,
-producing an integer ordinal that is used,
-a la @samp{temp0} in the earlier example,
-as if @samp{SELECT CASE(temp0)} had been written.
-
-Each corresponding @code{CASE} is replaced with @samp{CASE(@var{i})},
-where @var{i} is the ordinal for that case,
-determined while, or before,
-generating the cascade of @code{if}-related constructs
-to cope with @code{CHARACTER} selection.
-
-@item
-Make @samp{temp0} above just
-large enough to hold the longest @code{CASE} string
-that'll actually be compared against the expression
-(in this case, @samp{'prefix'//A}).
-
-Since that length must be constant
-(because @code{CASE} expressions are all constant),
-it won't be so large,
-and, further, @samp{temp1} need not be dynamically allocated,
-since normal @code{CHARACTER} assignment can be used
-into the fixed-length @samp{temp0}.
-@end itemize
-
-Both of these solutions require @code{SELECT CASE} implementation
-to be changed so all the corresponding @code{CASE} statements
-are seen during the actual code generation for @code{SELECT CASE}.
-
-@node Transforming Expressions
-@section Transforming Expressions
-
-The interactions between statements, expressions, and subexpressions
-at program run time can be viewed as:
-
-@smallexample
-@var{action}(@var{expr})
-@end smallexample
-
-Here, @var{action} is the series of steps
-performed to effect the statement,
-and @var{expr} is the expression
-whose value is used by @var{action}.
-
-Expanding the above shows a typical order of events at run time:
-
-@smallexample
-Evaluate @var{expr}
-Perform @var{action}, using result of evaluation of @var{expr}
-Clean up after evaluating @var{expr}
-@end smallexample
-
-So, if evaluating @var{expr} requires allocating memory,
-that memory can be freed before performing @var{action}
-only if it is not needed to hold the result of evaluating @var{expr}.
-Otherwise, it must be freed no sooner than
-after @var{action} has been performed.
-
-The above are recursive definitions,
-in the sense that they apply to subexpressions of @var{expr}.
-
-That is, evaluating @var{expr} involves
-evaluating all of its subexpressions,
-performing the @var{action} that computes the
-result value of @var{expr},
-then cleaning up after evaluating those subexpressions.
-
-The recursive nature of this evaluation is implemented
-via recursive-descent transformation of the top-level statements,
-their expressions, @emph{their} subexpressions, and so on.
-
-However, that recursive-descent transformation is,
-due to the nature of the GBEL,
-focused primarily on generating a @emph{single} stream of code
-to be executed at run time.
-
-Yet, from the above, it's clear that multiple streams of code
-must effectively be simultaneously generated
-during the recursive-descent analysis of statements.
-
-The primary stream implements the primary @var{action} items,
-while at least two other streams implement
-the evaluation and clean-up items.
-
-Requirements imposed by expressions include:
-
-@itemize @bullet
-@item
-Whether the caller needs to have a temporary ready
-to hold the value of the expression.
-
-@item
-Other stuff???

-@chapter What is GNU Fortran?
-@cindex concepts, basic
-@cindex basic concepts
-
-GNU Fortran, or @command{g77}, is designed initially as a free replacement
-for, or alternative to, the UNIX @command{f77} command.
-(Similarly, @command{gcc} is designed as a replacement
-for the UNIX @command{cc} command.)
-
-@command{g77} also is designed to fit in well with the other
-fine GNU compilers and tools.
-
-Sometimes these design goals conflict---in such cases, resolution
-often is made in favor of fitting in well with Project GNU.
-These cases are usually identified in the appropriate
-sections of this manual.
-
-@cindex compilers
-As compilers, @command{g77}, @command{gcc}, and @command{f77}
-share the following characteristics:
-
-@itemize @bullet
-@cindex source code
-@cindex file, source
-@cindex code, source
-@cindex source file
-@item
-They read a user's program, stored in a file and
-containing instructions written in the appropriate
-language (Fortran, C, and so on).
-This file contains @dfn{source code}.
-
-@cindex translation of user programs
-@cindex machine code
-@cindex code, machine
-@cindex mistakes
-@item
-They translate the user's program into instructions
-a computer can carry out more quickly than it takes
-to translate the instructions in the first place.
-These instructions are called @dfn{machine code}---code
-designed to be efficiently translated and processed
-by a machine such as a computer.
-Humans usually aren't as good writing machine code
-as they are at writing Fortran or C, because
-it is easy to make tiny mistakes writing machine code.
-When writing Fortran or C, it is easy
-to make big mistakes.
-
-@cindex debugger
-@cindex bugs, finding
-@cindex @command{gdb}, command
-@cindex commands, @command{gdb}
-@item
-They provide information in the generated machine code
-that can make it easier to find bugs in the program
-(using a debugging tool, called a @dfn{debugger},
-such as @command{gdb}).
-
-@cindex libraries
-@cindex linking
-@cindex @command{ld} command
-@cindex commands, @command{ld}
-@item
-They locate and gather machine code already generated
-to perform actions requested by statements in
-the user's program.
-This machine code is organized
-into @dfn{libraries} and is located and gathered
-during the @dfn{link} phase of the compilation
-process.
-(Linking often is thought of as a separate
-step, because it can be directly invoked via the
-@command{ld} command.
-However, the @command{g77} and @command{gcc}
-commands, as with most compiler commands, automatically
-perform the linking step by calling on @command{ld}
-directly, unless asked to not do so by the user.)
-
-@cindex language, incorrect use of
-@cindex incorrect use of language
-@item
-They attempt to diagnose cases where the user's
-program contains incorrect usages of the language.
-The @dfn{diagnostics} produced by the compiler
-indicate the problem and the location in the user's
-source file where the problem was first noticed.
-The user can use this information to locate and
-fix the problem.
-@cindex diagnostics, incorrect
-@cindex incorrect diagnostics
-@cindex error messages, incorrect
-@cindex incorrect error messages
-(Sometimes an incorrect usage
-of the language leads to a situation where the
-compiler can no longer make any sense of what
-follows---while a human might be able to---and
-thus ends up complaining about many ``problems''
-it encounters that, in fact, stem from just one
-problem, usually the first one reported.)
-
-@cindex warnings
-@cindex questionable instructions
-@item
-They attempt to diagnose cases where the user's
-program contains a correct usage of the language,
-but instructs the computer to do something questionable.
-These diagnostics often are in the form of @dfn{warnings},
-instead of the @dfn{errors} that indicate incorrect
-usage of the language.
-@end itemize
-
-How these actions are performed is generally under the
-control of the user.
-Using command-line options, the user can specify
-how persnickety the compiler is to be regarding
-the program (whether to diagnose questionable usage
-of the language), how much time to spend making
-the generated machine code run faster, and so on.
-
-@cindex components of @command{g77}
-@cindex @command{g77}, components of
-@command{g77} consists of several components:
-
-@cindex @command{gcc}, command
-@cindex commands, @command{gcc}
-@itemize @bullet
-@item
-A modified version of the @command{gcc} command, which also might be
-installed as the system's @command{cc} command.
-(In many cases, @command{cc} refers to the
-system's ``native'' C compiler, which
-might be a non-GNU compiler, or an older version
-of @command{gcc} considered more stable or that is
-used to build the operating system kernel.)
-
-@cindex @command{g77}, command
-@cindex commands, @command{g77}
-@item
-The @command{g77} command itself, which also might be installed as the
-system's @command{f77} command.

-@cindex libg2c library
-@cindex libf2c library
-@cindex libraries, libf2c
-@cindex libraries, libg2c
-@cindex run-time, library
-@item
-The @code{libg2c} run-time library.
-This library contains the machine code needed to support
-capabilities of the Fortran language that are not directly
-provided by the machine code generated by the @command{g77}
-compilation phase.
-
-@code{libg2c} is just the unique name @command{g77} gives
-to its version of @code{libf2c} to distinguish it from
-any copy of @code{libf2c} installed from @command{f2c}
-(or versions of @command{g77} that built @code{libf2c} under

-of machine code, leaving the conversion to actual machine code
-to an @dfn{assembler}, usually named @command{as}.
-@end itemize
-
-@command{gcc} is often thought of as ``the C compiler'' only,
-but it does more than that.
-Based on command-line options and the names given for files

-Instead, operations like trigonometric

-The same GBE is used by the C, C++, and Fortran compiler programs @code{cc1},
-@code{cc1plus}, and @code{f771}, plus others.

-majority of what is unique about GNU Fortran---the code that knows how
-to interpret Fortran programs to determine what they are intending to
-do, and then communicate that knowledge to the GBE for actual compilation
-of those programs.
-This chunk is called the @dfn{Fortran Front End} (FFE).
-The @code{cc1} and @code{cc1plus} programs have their own front ends,
-for the C and C++ languages, respectively.
-These fronts ends are responsible for diagnosing

-(The GBE handles producing some warnings, like those

-
-Because so much is shared among the compilers for various languages,
-much of the behavior and many of the user-selectable options for these

-For example, diagnostics (error messages and
-warnings) are similar in appearance; command-line
-options like @option{-Wall} have generally similar effects; and the quality
-of generated code (in terms of speed and size) is roughly similar
-(since that work is done by the shared GBE).

-@cindex ANSI FORTRAN 77 standard
-@cindex reference works
-GNU Fortran supports a variety of extensions to, and dialects
-of, the Fortran language.
-Its primary base is the ANSI FORTRAN 77 standard, currently available on
-the network at
-@uref{http://www.fortran.com/fortran/F77_std/rjcnf0001.html}
-or as monolithic text at
-@uref{http://www.fortran.com/fortran/F77_std/f77_std.html}.
-It offers some extensions that are popular among users
-of UNIX @command{f77} and @command{f2c} compilers, some that
-are popular among users of other compilers (such as Digital
-products), some that are popular among users of the
-newer Fortran 90 standard, and some that are introduced
-by GNU Fortran.
-
-@cindex textbooks
-(If you need a text on Fortran,
-a few freely available electronic references have pointers from
-@uref{http://www.fortran.com/F/books.html}. There is a `cooperative

-@uref{ftp://vms.huji.ac.il/fortran/} and mirrors elsewhere; some of this
-material might not apply specifically to @command{g77}.)
-
-Part of what defines a particular implementation of a Fortran
-system, such as @command{g77}, is the particular characteristics
-of how it supports types, constants, and so on.
-Much of this is left up to the implementation by the various

-@cindex features, language
-@cindex language, features
-
-The purpose of the following description of the GNU Fortran
-language is to promote wide portability of GNU Fortran programs.
-
-GNU Fortran is an evolving language, due to the
-fact that @command{g77} itself is in beta test.
-Some current features of the language might later
-be redefined as dialects of Fortran supported by @command{g77}
-when better ways to express these features are added to @command{g77},
-for example.
-Such features would still be supported by
-@command{g77}, but would be available only when
-one or more command-line options were used.
-
-The GNU Fortran @emph{language} is distinct from the
-GNU Fortran @emph{compilation system} (@command{g77}).
-
-For example, @command{g77} supports various dialects of
-Fortran---in a sense, these are languages other than
-GNU Fortran---though its primary
-purpose is to support the GNU Fortran language, which also is
-described in its documentation and by its implementation.
-
-On the other hand, non-GNU compilers might offer
-support for the GNU Fortran language, and are encouraged
-to do so.
-
-Currently, the GNU Fortran language is a fairly fuzzy object.
-It represents something of a cross between what @command{g77} accepts
-when compiling using the prevailing defaults and what this
-document describes as being part of the language.
-
-Future versions of @command{g77} are expected to clarify the
-definition of the language in the documentation.
-Often, this will mean adding new features to the language, in the form
-of both new documentation and new support in @command{g77}.
-However, it might occasionally mean removing a feature
-from the language itself to ``dialect'' status.
-In such a case, the documentation would be adjusted
-to reflect the change, and @command{g77} itself would likely be changed
-to require one or more command-line options to continue supporting
-the feature.
-
-The development of the GNU Fortran language is intended to strike
-a balance between:
-
-@itemize @bullet
-@item
-Serving as a mostly-upwards-compatible language from the
-de facto UNIX Fortran dialect as supported by @command{f77}.
-
-@item
-Offering new, well-designed language features.
-Attributes of such features include
-not making existing code any harder to read
-(for those who might be unaware that the new
-features are not in use) and
-not making state-of-the-art
-compilers take longer to issue diagnostics,
-among others.
-
-@item
-Supporting existing, well-written code without gratuitously
-rejecting non-standard constructs, regardless of the origin
-of the code (its dialect).
-
-@item
-Offering default behavior and command-line options to reduce
-and, where reasonable, eliminate the need for programmers to make
-any modifications to code that already works in existing
-production environments.
-
-@item
-Diagnosing constructs that have different meanings in different
-systems, languages, and dialects, while offering clear,
-less ambiguous ways to express each of the different meanings
-so programmers can change their code appropriately.
-@end itemize
-
-One of the biggest practical challenges for the developers of the
-GNU Fortran language is meeting the sometimes contradictory demands
-of the above items.
-
-For example, a feature might be widely used in one popular environment,
-but the exact same code that utilizes that feature might not work
-as expected---perhaps it might mean something entirely different---in
-another popular environment.
-
-Traditionally, Fortran compilers---even portable ones---have solved this
-problem by simply offering the appropriate feature to users of
-the respective systems.
-This approach treats users of various Fortran systems and dialects
-as remote ``islands'', or camps, of programmers, and assume that these
-camps rarely come into contact with each other (or,
-especially, with each other's code).
-
-Project GNU takes a radically different approach to software and language
-design, in that it assumes that users of GNU software do not necessarily
-care what kind of underlying system they are using, regardless
-of whether they are using software (at the user-interface
-level) or writing it (for example, writing Fortran or C code).
-
-As such, GNU users rarely need consider just what kind of underlying
-hardware (or, in many cases, operating system) they are using at any
-particular time.
-They can use and write software designed for a general-purpose,
-widely portable, heterogeneous environment---the GNU environment.
-
-In line with this philosophy, GNU Fortran must evolve into a product
-that is widely ported and portable not only in the sense that it can
-be successfully built, installed, and run by users, but in the larger
-sense that its users can use it in the same way, and expect largely the
-same behaviors from it, regardless of the kind of system they are using
-at any particular time.
-
-This approach constrains the solutions @command{g77} can use to resolve
-conflicts between various camps of Fortran users.
-If these two camps disagree about what a particular construct should
-mean, @command{g77} cannot simply be changed to treat that particular construct as
-having one meaning without comment (such as a warning), lest the users
-expecting it to have the other meaning are unpleasantly surprised that
-their code misbehaves when executed.
-
-The use of the ASCII backslash character in character constants is
-an excellent (and still somewhat unresolved) example of this kind of
-controversy.
-@xref{Backslash in Constants}.
-Other examples are likely to arise in the future, as @command{g77} developers
-strive to improve its ability to accept an ever-wider variety of existing
-Fortran code without requiring significant modifications to said code.
-
-Development of GNU Fortran is further constrained by the desire
-to avoid requiring programmers to change their code.
-This is important because it allows programmers, administrators,
-and others to more faithfully evaluate and validate @command{g77}
-(as an overall product and as new versions are distributed)
-without having to support multiple versions of their programs
-so that they continue to work the same way on their existing
-systems (non-GNU perhaps, but possibly also earlier versions
-of @command{g77}).

-
-The definition of the GNU Fortran language is akin to that of
-the ANSI FORTRAN 77 language in that it does not generally require
-conforming implementations to diagnose cases where programs do
-not conform to the language.
-
-However, @command{g77} as a compiler is being developed in a way that
-is intended to enable it to diagnose such cases in an easy-to-understand
-manner.
-
-A program that conforms to the GNU Fortran language should, when
-compiled, linked, and executed using a properly installed @command{g77}
-system, perform as described by the GNU Fortran language definition.
-Reasons for different behavior include, among others:
-
-@itemize @bullet
-@item
-Use of resources (memory---heap, stack, and so on; disk space; CPU
-time; etc.) exceeds those of the system.
-
-@item
-Range and/or precision of calculations required by the program
-exceeds that of the system.
-
-@item
-Excessive reliance on behaviors that are system-dependent
-(non-portable Fortran code).
-
-@item
-Bugs in the program.
-
-@item
-Bug in @command{g77}.
-
-@item
-Bugs in the system.
-@end itemize
-
-Despite these ``loopholes'', the availability of a clear specification
-of the language of programs submitted to @command{g77}, as this document
-is intended to provide, is considered an important aspect of providing
-a robust, clean, predictable Fortran implementation.
-
-The definition of the GNU Fortran language, while having no special
-legal status, can therefore be viewed as a sort of contract, or agreement.
-This agreement says, in essence, ``if you write a program in this language,
-and run it in an environment (such as a @command{g77} system) that supports
-this language, the program should behave in a largely predictable way''.

-In this chapter, ``must'' denotes a requirement, ``may'' denotes permission,
-and ``must not'' and ``may not'' denote prohibition.
-Terms such as ``might'', ``should'', and ``can'' generally add little or

-
-For example:
-
-@display
-``The @code{FROBNITZ} statement must precede all executable
-statements in a program unit, and may not specify any dummy
-arguments. It may specify local or common variables and arrays.
-Its use should be limited to portions of the program designed to

-
-Insofar as the GNU Fortran language is specified,
-the requirements and permissions denoted by the above sample statement
-are limited to the placement of the statement and the kinds of
-things it may specify.
-The rest of the statement---the content regarding non-portable portions
-of the program and the differing behavior of program units containing
-the @code{FROBNITZ} statement---does not pertain the GNU Fortran
-language itself.
-That content offers advice and warnings about the @code{FROBNITZ}
-statement.
-
-@emph{Remember:} The GNU Fortran language definition specifies
-both what constitutes a valid GNU Fortran program and how,
-given such a program, a valid GNU Fortran implementation is
-to interpret that program.
-
-It is @emph{not} incumbent upon a valid GNU Fortran implementation
-to behave in any particular way, any consistent way, or any
-predictable way when it is asked to interpret input that is
-@emph{not} a valid GNU Fortran program.
-
-Such input is said to have @dfn{undefined} behavior when
-interpreted by a valid GNU Fortran implementation, though
-an implementation may choose to specify behaviors for some
-cases of inputs that are not valid GNU Fortran programs.

-Portions of actual sample program, input, or output text

-A metasyntactic variable---that is, a name used in this document
-to serve as a placeholder for whatever text is used by the

-(Corresponds to Section 3.2 of ANSI X3.9-1978 FORTRAN 77.)
-
-The way a Fortran compiler views source files depends entirely on the
-implementation choices made for the compiler, since those choices
-are explicitly left to the implementation by the published Fortran
-standards.
-
-The GNU Fortran language mandates a view applicable to UNIX-like
-text files---files that are made up of an arbitrary number of lines,
-each with an arbitrary number of characters (sometimes called stream-based
-files).
-
-This view does not apply to types of files that are specified as
-having a particular number of characters on every single line (sometimes
-referred to as record-based files).
-
-Because a ``line in a program unit is a sequence of 72 characters'',
-to quote X3.9-1978, the GNU Fortran language specifies that a
-stream-based text file is translated to GNU Fortran lines as follows:
-
-@itemize @bullet
-@item
-A newline in the file is the character that represents the end of
-a line of text to the underlying system.
-For example, on ASCII-based systems, a newline is the @key{NL}
-character, which has ASCII value 10 (decimal).
-
-@item
-Each newline in the file serves to end the line of text that precedes
-it (and that does not contain a newline).
-
-@item
-The end-of-file marker (@code{EOF}) also serves to end the line
-of text that precedes it (and that does not contain a newline).
-
-@item
-@cindex blank
-@cindex space
-@cindex SPC
-Any line of text that is shorter than 72 characters is padded to that length
-with spaces (called ``blanks'' in the standard).
-
-@item
-Any line of text that is longer than 72 characters is truncated to that
-length, but the truncated remainder must consist entirely of spaces.
-
-@item
-Characters other than newline and the GNU Fortran character set
-are invalid.
-@end itemize
-
-For the purposes of the remainder of this description of the GNU
-Fortran language, the translation described above has already
-taken place, unless otherwise specified.
-
-The result of the above translation is that the source file appears,
-in terms of the remainder of this description of the GNU Fortran language,
-as if it had an arbitrary
-number of 72-character lines, each character being among the GNU Fortran
-character set.
-
-For example, if the source file itself has two newlines in a row,
-the second newline becomes, after the above translation, a single
-line containing 72 spaces.

-7 through 72 of a line that has only spaces to the left of that
-digit.
-
-The continuation character is ignored as far as the content of
-the statement is concerned.
-
-The GNU Fortran language places no limit on the number of
-continuation lines in a statement.
-In practice, the limit depends on a variety of factors, such as
-available memory, statement content, and so on, but no
-GNU Fortran system may impose an arbitrary limit.

-

-Statements may be separated using the semicolon (@samp{;}), except
-that the logical @code{IF} and non-construct @code{WHERE} statements
-may not be separated from subsequent statements using only a semicolon
-as statement separator.
-
-The @code{END PROGRAM}, @code{END SUBROUTINE}, @code{END FUNCTION},
-and @code{END BLOCK DATA} statements are alternatives to the @code{END}
-statement.
-These alternatives may be written as normal statements---they are not
-subject to the restrictions of the @code{END} statement.
-
-However, no statement other than @code{END} may have an initial line
-that appears to be an @code{END} statement---even @code{END PROGRAM},

-The semicolon is followed by the label for the statement,
-which in turn follows the label.
-
-@item
-The label must be no more than five digits in length.
-
-@item
-The first digit of the label for the statement is not
-the first non-space character on a line.

-
-@node Order
-@subsection Order of Statements and Lines
-
-(Corresponds to Section 3.5 of ANSI X3.9-1978 FORTRAN 77.)
-
-Generally, @code{DATA} statements may precede executable statements.
-However, specification statements pertaining to any entities
-initialized by a @code{DATA} statement must precede that @code{DATA}
-statement.
-For example,
-after @samp{DATA I/1/}, @samp{INTEGER I} is not permitted, but
-@samp{INTEGER J} is permitted.
-
-The last line of a program unit may be an @code{END} statement,

-@node INCLUDE
-@subsection Including Source Text
-@cindex INCLUDE directive
-
-Additional source text may be included in the processing of
-the source file via the @code{INCLUDE} directive:
-
-@example
-INCLUDE @var{filename}
-@end example
-
-@noindent
-The source text to be included is identified by @var{filename},
-which is a literal GNU Fortran character constant.
-The meaning and interpretation of @var{filename} depends on the
-implementation, but typically is a filename.
-
-(@command{g77} treats it as a filename that it searches for
-in the current directory and/or directories specified
-via the @option{-I} command-line option.)
-
-The effect of the @code{INCLUDE} directive is as if the
-included text directly replaced the directive in the source
-file prior to interpretation of the program.
-Included text may itself use @code{INCLUDE}.
-The depth of nested @code{INCLUDE} references depends on
-the implementation, but typically is a positive integer.
-
-This virtual replacement treats the statements and @code{INCLUDE}
-directives in the included text as syntactically distinct from
-those in the including text.
-
-Therefore, the first non-comment line of the included text
-must not be a continuation line.
-The included text must therefore have, after the non-comment
-lines, either an initial line (statement), an @code{INCLUDE}
-directive, or nothing (the end of the included text).
-
-Similarly, the including text may end the @code{INCLUDE}
-directive with a semicolon or the end of the line, but it
-cannot follow an @code{INCLUDE} directive at the end of its
-line with a continuation line.
-Thus, the last statement in an included text may not be
-continued.
-
-Any statements between two @code{INCLUDE} directives on the
-same line are treated as if they appeared in between the
-respective included texts.
-For example:
-
-@smallexample
-INCLUDE 'A'; PRINT *, 'B'; INCLUDE 'C'; END PROGRAM
-@end smallexample
-
-@noindent
-If the text included by @samp{INCLUDE 'A'} constitutes
-a @samp{PRINT *, 'A'} statement and the text included by
-@samp{INCLUDE 'C'} constitutes a @samp{PRINT *, 'C'} statement,
-then the output of the above sample program would be
-
-@example
-A
-B
-C
-@end example
-
-@noindent
-(with suitable allowances for how an implementation defines
-its handling of output).
-
-Included text must not include itself directly or indirectly,
-regardless of whether the @var{filename} used to reference
-the text is the same.
-
-Note that @code{INCLUDE} is @emph{not} a statement.
-As such, it is neither a non-executable or executable
-statement.
-However, if the text it includes constitutes one or more
-executable statements, then the placement of @code{INCLUDE}
-is subject to effectively the same restrictions as those
-on executable statements.
-
-An @code{INCLUDE} directive may be continued across multiple
-lines as if it were a statement.
-This permits long names to be used for @var{filename}.

-Chapter 4 of ANSI X3.9-1978 FORTRAN 77 in specifying the GNU Fortran
-language.
-Chapter 4 of that document otherwise serves as the basis
-for the relevant aspects of GNU Fortran.)
-
-To more concisely express the appropriate types for
-entities, this document uses the more concise
-Fortran 90 nomenclature such as @code{INTEGER(KIND=1)}
-instead of the more traditional, but less portably concise,
-byte-size-based nomenclature such as @code{INTEGER*4},
-wherever reasonable.
-
-When referring to generic types---in contexts where the
-specific precision and range of a type are not important---this
-document uses the generic type names @code{INTEGER}, @code{LOGICAL},
-@code{REAL}, @code{COMPLEX}, and @code{CHARACTER}.
-
-In some cases, the context requires specification of a
-particular type.
-This document uses the @samp{KIND=} notation to accomplish
-this throughout, sometimes supplying the more traditional
-notation for clarification, though the traditional notation
-might not work the same way on all GNU Fortran implementations.
-
-Use of @samp{KIND=} makes this document more concise because
-@command{g77} is able to define values for @samp{KIND=} that
-have the same meanings on all systems, due to the way the
-Fortran 90 standard specifies these values are to be used.
-
-(In particular, that standard permits an implementation to
-arbitrarily assign nonnegative values.
-There are four distinct sets of assignments: one to the @code{CHARACTER}
-type; one to the @code{INTEGER} type; one to the @code{LOGICAL} type;
-and the fourth to both the @code{REAL} and @code{COMPLEX} types.
-Implementations are free to assign these values in any order,
-leave gaps in the ordering of assignments, and assign more than
-one value to a representation.)
-
-This makes @samp{KIND=} values superior to the values used
-in non-standard statements such as @samp{INTEGER*4}, because
-the meanings of the values in those statements vary from machine
-to machine, compiler to compiler, even operating system to
-operating system.
-
-However, use of @samp{KIND=} is @emph{not} generally recommended
-when writing portable code (unless, for example, the code is
-going to be compiled only via @command{g77}, which is a widely
-ported compiler).
-GNU Fortran does not yet have adequate language constructs to
-permit use of @samp{KIND=} in a fashion that would make the
-code portable to Fortran 90 implementations; and, this construct
-is known to @emph{not} be accepted by many popular FORTRAN 77
-implementations, so it cannot be used in code that is to be ported
-to those.
-
-The distinction here is that this document is able to use
-specific values for @samp{KIND=} to concisely document the
-types of various operations and operands.
-
-A Fortran program should use the FORTRAN 77 designations for the
-appropriate GNU Fortran types---such as @code{INTEGER} for
-@code{INTEGER(KIND=1)}, @code{REAL} for @code{REAL(KIND=1)},
-and @code{DOUBLE COMPLEX} for @code{COMPLEX(KIND=2)}---and,
-where no such designations exist, make use of appropriate
-techniques (preprocessor macros, parameters, and so on)
-to specify the types in a fashion that may be easily adjusted
-to suit each particular implementation to which the program
-is ported.

-@command{g77}.)

-
-For example, a context described in this document as accepting

-@node Double Notation
-@subsubsection Double Notation
-
-The GNU Fortran language supports two uses of the keyword
-@code{DOUBLE} to specify a specific kind of type:
-
-@itemize @bullet
-@item
-@code{DOUBLE PRECISION}, equivalent to @code{REAL(KIND=2)}
-
-@item
-@code{DOUBLE COMPLEX}, equivalent to @code{COMPLEX(KIND=2)}
-@end itemize
-
-Use one of the above forms where a type name is valid.
-
-While use of this notation is popular, it doesn't scale
-well in a language or dialect rich in intrinsic types,
-as is the case for the GNU Fortran language (especially
-planned future versions of it).
-
-After all, one rarely sees type names such as @samp{DOUBLE INTEGER},
-@samp{QUADRUPLE REAL}, or @samp{QUARTER INTEGER}.
-Instead, @code{INTEGER*8}, @code{REAL*16}, and @code{INTEGER*1}
-often are substituted for these, respectively, even though they
-do not always have the same meanings on all systems.
-(And, the fact that @samp{DOUBLE REAL} does not exist as such
-is an inconsistency.)
-
-Therefore, this document uses ``double notation'' only on occasion
-for the benefit of those readers who are accustomed to it.
-
-@node Star Notation
-@subsubsection Star Notation
-@cindex *@var{n} notation
-
-The following notation specifies the storage size for a type:
-
-@smallexample
-@var{generic-type}*@var{n}
-@end smallexample
-
-@noindent
-@var{generic-type} must be a generic type---one of
-@code{INTEGER}, @code{REAL}, @code{COMPLEX}, @code{LOGICAL},
-or @code{CHARACTER}.
-@var{n} must be one or more digits comprising a decimal
-integer number greater than zero.
-
-Use the above form where a type name is valid.
-
-The @samp{*@var{n}} notation specifies that the amount of storage
-occupied by variables and array elements of that type is @var{n}
-times the storage occupied by a @code{CHARACTER*1} variable.
-
-This notation might indicate a different degree of precision and/or
-range for such variables and array elements, and the functions that
-return values of types using this notation.
-It does not limit the precision or range of values of that type
-in any particular way---use explicit code to do that.
-
-Further, the GNU Fortran language requires no particular values
-for @var{n} to be supported by an implementation via the @samp{*@var{n}}
-notation.
-@command{g77} supports @code{INTEGER*1} (as @code{INTEGER(KIND=3)})
-on all systems, for example,
-but not all implementations are required to do so, and @command{g77}
-is known to not support @code{REAL*1} on most (or all) systems.
-
-As a result, except for @var{generic-type} of @code{CHARACTER},
-uses of this notation should be limited to isolated
-portions of a program that are intended to handle system-specific
-tasks and are expected to be non-portable.
-
-(Standard FORTRAN 77 supports the @samp{*@var{n}} notation for
-only @code{CHARACTER}, where it signifies not only the amount
-of storage occupied, but the number of characters in entities
-of that type.
-However, almost all Fortran compilers have supported this
-notation for generic types, though with a variety of meanings
-for @var{n}.)
-
-Specifications of types using the @samp{*@var{n}} notation
-always are interpreted as specifications of the appropriate
-types described in this document using the @samp{KIND=@var{n}}
-notation, described below.
-
-While use of this notation is popular, it doesn't serve well
-in the context of a widely portable dialect of Fortran, such as
-the GNU Fortran language.
-
-For example, even on one particular machine, two or more popular
-Fortran compilers might well disagree on the size of a type
-declared @code{INTEGER*2} or @code{REAL*16}.
-Certainly there
-is known to be disagreement over such things among Fortran
-compilers on @emph{different} systems.
-
-Further, this notation offers no elegant way to specify sizes
-that are not even multiples of the ``byte size'' typically
-designated by @code{INTEGER*1}.
-Use of ``absurd'' values (such as @code{INTEGER*1000}) would
-certainly be possible, but would perhaps be stretching the original
-intent of this notation beyond the breaking point in terms
-of widespread readability of documentation and code making use
-of it.
-
-Therefore, this document uses ``star notation'' only on occasion
-for the benefit of those readers who are accustomed to it.
-
-@node Kind Notation
-@subsubsection Kind Notation
-@cindex KIND= notation
-
-The following notation specifies the kind-type selector of a type:
-
-@smallexample
-@var{generic-type}(KIND=@var{n})
-@end smallexample
-
-@noindent
-Use the above form where a type name is valid.
-
-@var{generic-type} must be a generic type---one of
-@code{INTEGER}, @code{REAL}, @code{COMPLEX}, @code{LOGICAL},
-or @code{CHARACTER}.
-@var{n} must be an integer initialization expression that
-is a positive, nonzero value.
-
-Programmers are discouraged from writing these values directly
-into their code.
-Future versions of the GNU Fortran language will offer
-facilities that will make the writing of code portable
-to @command{g77} @emph{and} Fortran 90 implementations simpler.
-
-However, writing code that ports to existing FORTRAN 77
-implementations depends on avoiding the @samp{KIND=} construct.
-
-The @samp{KIND=} construct is thus useful in the context
-of GNU Fortran for two reasons:
-
-@itemize @bullet
-@item
-It provides a means to specify a type in a fashion that
-is portable across all GNU Fortran implementations (though
-not other FORTRAN 77 and Fortran 90 implementations).
-
-@item
-It provides a sort of Rosetta stone for this document to use
-to concisely describe the types of various operations and
-operands.
-@end itemize
-
-The values of @var{n} in the GNU Fortran language are
-assigned using a scheme that:
-
-@itemize @bullet
-@item
-Attempts to maximize the ability of readers
-of this document to quickly familiarize themselves
-with assignments for popular types
-
-@item
-Provides a unique value for each specific desired
-meaning
-
-@item
-Provides a means to automatically assign new values so
-they have a ``natural'' relationship to existing values,
-if appropriate, or, if no such relationship exists, will
-not interfere with future values assigned on the basis
-of such relationships
-
-@item
-Avoids using values that are similar to values used
-in the existing, popular @samp{*@var{n}} notation,
-to prevent readers from expecting that these implied
-correspondences work on all GNU Fortran implementations
-@end itemize
-
-The assignment system accomplishes this by assigning
-to each ``fundamental meaning'' of a specific type a
-unique prime number.
-Combinations of fundamental meanings---for example, a type
-that is two times the size of some other type---are assigned
-values of @var{n} that are the products of the values for
-those fundamental meanings.
-
-A prime value of @var{n} is never given more than one fundamental
-meaning, to avoid situations where some code or system
-cannot reasonably provide those meanings in the form of a
-single type.
-
-The values of @var{n} assigned so far are:
-
-@table @code
-@item KIND=0
-This value is reserved for future use.
-
-The planned future use is for this value to designate,
-explicitly, context-sensitive kind-type selection.
-For example, the expression @samp{1D0 * 0.1_0} would
-be equivalent to @samp{1D0 * 0.1D0}.
-
-@item KIND=1
-This corresponds to the default types for
-@code{REAL}, @code{INTEGER}, @code{LOGICAL}, @code{COMPLEX},
-and @code{CHARACTER}, as appropriate.
-
-These are the ``default'' types described in the Fortran 90 standard,
-though that standard does not assign any particular @samp{KIND=}
-value to these types.
-
-(Typically, these are @code{REAL*4}, @code{INTEGER*4},
-@code{LOGICAL*4}, and @code{COMPLEX*8}.)
-
-@item KIND=2
-This corresponds to types that occupy twice as much

-@code{REAL(KIND=2)} is @code{DOUBLE PRECISION} (typically @code{REAL*8}),
-@code{COMPLEX(KIND=2)} is @code{DOUBLE COMPLEX} (typically @code{COMPLEX*16}),
-
-These are the ``double precision'' types described in the Fortran 90
-standard,
-though that standard does not assign any particular @samp{KIND=}
-value to these types.
-
-@var{n} of 4 thus corresponds to types that occupy four times
-as much storage as the default types, @var{n} of 8 to types that
-occupy eight times as much storage, and so on.
-
-The @code{INTEGER(KIND=2)} and @code{LOGICAL(KIND=2)} types
-are not necessarily supported by every GNU Fortran implementation.
-
-@item KIND=3
-This corresponds to types that occupy as much
-storage as the default @code{CHARACTER} type,
-which is the same effective type as @code{CHARACTER(KIND=1)}
-(making that type effectively the same as @code{CHARACTER(KIND=3)}).
-
-(Typically, these are @code{INTEGER*1} and @code{LOGICAL*1}.)
-
-@var{n} of 6 thus corresponds to types that occupy twice as
-much storage as the @var{n}=3 types, @var{n} of 12 to types
-that occupy four times as much storage, and so on.
-
-These are not necessarily supported by every GNU Fortran
-implementation.
-
-@item KIND=5
-This corresponds to types that occupy half the
-storage as the default (@var{n}=1) types.
-
-(Typically, these are @code{INTEGER*2} and @code{LOGICAL*2}.)
-
-@var{n} of 25 thus corresponds to types that occupy one-quarter
-as much storage as the default types.
-
-These are not necessarily supported by every GNU Fortran
-implementation.
-
-@item KIND=7
-@cindex pointers
-This is valid only as @code{INTEGER(KIND=7)} and
-denotes the @code{INTEGER} type that has the smallest
-storage size that holds a pointer on the system.
-
-A pointer representable by this type is capable of uniquely
-addressing a @code{CHARACTER*1} variable, array, array element,
-or substring.
-
-(Typically this is equivalent to @code{INTEGER*4} or,
-on 64-bit systems, @code{INTEGER*8}.
-In a compatible C implementation, it typically would
-be the same size and semantics of the C type @code{void *}.)
-@end table
-
-Note that these are @emph{proposed} correspondences and might change
-in future versions of @command{g77}---avoid writing code depending
-on them while @command{g77}, and therefore the GNU Fortran language
-it defines, is in beta testing.
-
-Values not specified in the above list are reserved to
-future versions of the GNU Fortran language.
-
-Implementation-dependent meanings will be assigned new,
-unique prime numbers so as to not interfere with other
-implementation-dependent meanings, and offer the possibility
-of increasing the portability of code depending on such
-types by offering support for them in other GNU Fortran
-implementations.
-
-Other meanings that might be given unique values are:
-
-@itemize @bullet
-@item
-Types that make use of only half their storage size for
-representing precision and range.
-
-For example, some compilers offer options that cause
-@code{INTEGER} types to occupy the amount of storage
-that would be needed for @code{INTEGER(KIND=2)} types, but the
-range remains that of @code{INTEGER(KIND=1)}.
-
-@item
-The IEEE single floating-point type.
-
-@item
-Types with a specific bit pattern (endianness), such as the
-little-endian form of @code{INTEGER(KIND=1)}.
-These could permit, conceptually, use of portable code and
-implementations on data files written by existing systems.
-@end itemize
-
-Future @emph{prime} numbers should be given meanings in as incremental
-a fashion as possible, to allow for flexibility and
-expressiveness in combining types.
-
-For example, instead of defining a prime number for little-endian
-IEEE doubles, one prime number might be assigned the meaning
-``little-endian'', another the meaning ``IEEE double'', and the
-value of @var{n} for a little-endian IEEE double would thus
-naturally be the product of those two respective assigned values.
-(It could even be reasonable to have IEEE values result from the
-products of prime values denoting exponent and fraction sizes
-and meanings, hidden bit usage, availability and representations
-of special values such as subnormals, infinities, and Not-A-Numbers
-(NaNs), and so on.)
-
-This assignment mechanism, while not inherently required for
-future versions of the GNU Fortran language, is worth using
-because it could ease management of the ``space'' of supported
-types much easier in the long run.
-
-The above approach suggests a mechanism for specifying inheritance
-of intrinsic (built-in) types for an entire, widely portable
-product line.
-It is certainly reasonable that, unlike programmers of other languages
-offering inheritance mechanisms that employ verbose names for classes
-and subclasses, along with graphical browsers to elucidate the
-relationships, Fortran programmers would employ
-a mechanism that works by multiplying prime numbers together
-and finding the prime factors of such products.
-
-Most of the advantages for the above scheme have been explained
-above.
-One disadvantage is that it could lead to the defining,
-by the GNU Fortran language, of some fairly large prime numbers.
-This could lead to the GNU Fortran language being declared
-``munitions'' by the United States Department of Defense.

-@node %LOC()
-@subsection The @code{%LOC()} Construct
-@cindex %LOC() construct
-
-@example
-%LOC(@var{arg})
-@end example
-
-The @code{%LOC()} construct is an expression
-that yields the value of the location of its argument,
-@var{arg}, in memory.
-The size of the type of the expression depends on the system---typically,
-it is equivalent to either @code{INTEGER(KIND=1)} or @code{INTEGER(KIND=2)},
-though it is actually type @code{INTEGER(KIND=7)}.
-
-The argument to @code{%LOC()} must be suitable as the
-left-hand side of an assignment statement.
-That is, it may not be a general expression involving
-operators such as addition, subtraction, and so on,
-nor may it be a constant.
-
-Use of @code{%LOC()} is recommended only for code that
-is accessing facilities outside of GNU Fortran, such as
-operating system or windowing facilities.
-It is best to constrain such uses to isolated portions of
-a program---portions that deal specifically and exclusively
-with low-level, system-dependent facilities.
-Such portions might well provide a portable interface for
-use by the program as a whole, but are themselves not
-portable, and should be thoroughly tested each time they
-are rebuilt using a new compiler or version of a compiler.
-
-Do not depend on @code{%LOC()} returning a pointer that
-can be safely used to @emph{define} (change) the argument.
-While this might work in some circumstances, it is hard
-to predict whether it will continue to work when a program
-(that works using this unsafe behavior)
-is recompiled using different command-line options or
-a different version of @command{g77}.
-
-Generally, @code{%LOC()} is safe when used as an argument
-to a procedure that makes use of the value of the corresponding
-dummy argument only during its activation, and only when
-such use is restricted to referencing (reading) the value
-of the argument to @code{%LOC()}.
-
-@emph{Implementation Note:} Currently, @command{g77} passes
-arguments (those not passed using a construct such as @code{%VAL()})
-by reference or descriptor, depending on the type of
-the actual argument.
-Thus, given @samp{INTEGER I}, @samp{CALL FOO(I)} would
-seem to mean the same thing as @samp{CALL FOO(%VAL(%LOC(I)))}, and
-in fact might compile to identical code.
-
-However, @samp{CALL FOO(%VAL(%LOC(I)))} emphatically means
-``pass, by value, the address of @samp{I} in memory''.
-While @samp{CALL FOO(I)} might use that same approach in a
-particular version of @command{g77}, another version or compiler
-might choose a different implementation, such as copy-in/copy-out,
-to effect the desired behavior---and which will therefore not
-necessarily compile to the same code as would
-@samp{CALL FOO(%VAL(%LOC(I)))}
-using the same version or compiler.

-The @code{DO WHILE} statement, a feature of both the MIL-STD 1753 and

-
-The @code{END DO} statement is provided by the GNU Fortran language.
-
-This statement is used in one of two ways:
-
-@itemize @bullet
-@item
-The Fortran 90 meaning, in which it specifies the termination
-point of a single @code{DO} loop started with a @code{DO} statement
-that specifies no termination label.
-
-@item
-The MIL-STD 1753 meaning, in which it specifies the termination
-point of one or more @code{DO} loops, all of which start with a
-@code{DO} statement that specify the label defined for the
-@code{END DO} statement.
-
-This kind of @code{END DO} statement is merely a synonym for
-@code{CONTINUE}, except it is permitted only when the statement
-is labeled and a target of one or more labeled @code{DO} loops.
-
-It is expected that this use of @code{END DO} will be removed from

-
-@node Construct Names
-@subsection Construct Names
-@cindex construct names
-
-The GNU Fortran language supports construct names as defined
-by the Fortran 90 standard.
-These names are local to the program unit and are defined
-as follows:
-
-@smallexample
-@var{construct-name}: @var{block-statement}
-@end smallexample
-
-@noindent
-Here, @var{construct-name} is the construct name itself;
-its definition is connoted by the single colon (@samp{:}); and
-@var{block-statement} is an @code{IF}, @code{DO},
-or @code{SELECT CASE} statement that begins a block.
-
-A block that is given a construct name must also specify the
-same construct name in its termination statement:
-
-@example
-END @var{block} @var{construct-name}
-@end example
-
-@noindent
-Here, @var{block} must be @code{IF}, @code{DO}, or @code{SELECT},

-
-@node CYCLE and EXIT
-@subsection The @code{CYCLE} and @code{EXIT} Statements
-
-@cindex CYCLE statement
-@cindex EXIT statement
-@cindex statements, CYCLE
-@cindex statements, EXIT
-The @code{CYCLE} and @code{EXIT} statements specify that
-the remaining statements in the current iteration of a
-particular active (enclosing) @code{DO} loop are to be skipped.
-
-@code{CYCLE} specifies that these statements are skipped,
-but the @code{END DO} statement that marks the end of the
-@code{DO} loop be executed---that is, the next iteration,
-if any, is to be started.
-If the statement marking the end of the @code{DO} loop is
-not @code{END DO}---in other words, if the loop is not
-a block @code{DO}---the @code{CYCLE} statement does not
-execute that statement, but does start the next iteration (if any).
-
-@code{EXIT} specifies that the loop specified by the
-@code{DO} construct is terminated.
-
-The @code{DO} loop affected by @code{CYCLE} and @code{EXIT}
-is the innermost enclosing @code{DO} loop when the following
-forms are used:
-
-@example
-CYCLE
-EXIT
-@end example
-
-Otherwise, the following forms specify the construct name
-of the pertinent @code{DO} loop:
-
-@example
-CYCLE @var{construct-name}
-EXIT @var{construct-name}
-@end example
-
-@code{CYCLE} and @code{EXIT} can be viewed as glorified @code{GO TO}
-statements.
-However, they cannot be easily thought of as @code{GO TO} statements
-in obscure cases involving FORTRAN 77 loops.
-For example:
-
-@smallexample
- DO 10 I = 1, 5
- DO 10 J = 1, 5
- IF (J .EQ. 5) EXIT
- DO 10 K = 1, 5
- IF (K .EQ. 3) CYCLE
-10 PRINT *, 'I=', I, ' J=', J, ' K=', K
-20 CONTINUE
-@end smallexample
-
-@noindent
-In particular, neither the @code{EXIT} nor @code{CYCLE} statements
-above are equivalent to a @code{GO TO} statement to either label
-@samp{10} or @samp{20}.
-
-To understand the effect of @code{CYCLE} and @code{EXIT} in the
-above fragment, it is helpful to first translate it to its equivalent
-using only block @code{DO} loops:
-
-@smallexample
- DO I = 1, 5
- DO J = 1, 5
- IF (J .EQ. 5) EXIT
- DO K = 1, 5
- IF (K .EQ. 3) CYCLE
-10 PRINT *, 'I=', I, ' J=', J, ' K=', K
- END DO
- END DO
- END DO
-20 CONTINUE
-@end smallexample
-
-Adding new labels allows translation of @code{CYCLE} and @code{EXIT}
-to @code{GO TO} so they may be more easily understood by programmers
-accustomed to FORTRAN coding:
-
-@smallexample
- DO I = 1, 5
- DO J = 1, 5
- IF (J .EQ. 5) GOTO 18
- DO K = 1, 5
- IF (K .EQ. 3) GO TO 12
-10 PRINT *, 'I=', I, ' J=', J, ' K=', K
-12 END DO
- END DO
-18 END DO
-20 CONTINUE
-@end smallexample
-
-@noindent
-Thus, the @code{CYCLE} statement in the innermost loop skips over
-the @code{PRINT} statement as it begins the next iteration of the
-loop, while the @code{EXIT} statement in the middle loop ends that
-loop but @emph{not} the outermost loop.

-@end itemize
-
-The GNU Fortran language generalizes these concepts somewhat,
-especially by providing intrinsic subroutines and generic
-intrinsics that are treated as either a specific intrinsic subroutine
-or a specific intrinsic function (e.g. @code{SECOND}).
-
-However, GNU Fortran avoids generalizing this concept to
-the point where existing code would be accepted as meaning
-something possibly different than what was intended.
-
-For example, @code{ABS} is a generic intrinsic, so all working
-code written using @code{ABS} of an @code{INTEGER} argument
-expects an @code{INTEGER} return value.
-Similarly, all such code expects that @code{ABS} of an @code{INTEGER*2}
-argument returns an @code{INTEGER*2} return value.
-
-Yet, @code{IABS} is a @emph{specific} intrinsic that accepts only
-an @code{INTEGER(KIND=1)} argument.
-Code that passes something other than an @code{INTEGER(KIND=1)}
-argument to @code{IABS} is not valid GNU Fortran code, because
-it is not clear what the author intended.
-
-For example, if @samp{J} is @code{INTEGER(KIND=6)}, @samp{IABS(J)}
-is not defined by the GNU Fortran language, because the programmer
-might have used that construct to mean any of the following, subtly
-different, things:
-
-@itemize @bullet
-@item
-Convert @samp{J} to @code{INTEGER(KIND=1)} first
-(as if @samp{IABS(INT(J))} had been written).
-
-@item
-Convert the result of the intrinsic to @code{INTEGER(KIND=1)}
-(as if @samp{INT(ABS(J))} had been written).
-
-@item
-No conversion (as if @samp{ABS(J)} had been written).
-@end itemize
-
-The distinctions matter especially when types and values wider than
-@code{INTEGER(KIND=1)} (such as @code{INTEGER(KIND=2)}), or when
-operations performing more ``arithmetic'' than absolute-value, are involved.
-
-The following sample program is not a valid GNU Fortran program, but
-might be accepted by other compilers.
-If so, the output is likely to be revealing in terms of how a given
-compiler treats intrinsics (that normally are specific) when they
-are given arguments that do not conform to their stated requirements:

-No future version of the GNU Fortran language
-will likely permit specific intrinsic invocations with wrong-typed
-arguments (such as @code{IDIM} in the above example), since
-it has been determined that disagreements exist among
-many production compilers on the interpretation of
-such invocations.
-These disagreements strongly suggest that Fortran programmers,
-and certainly existing Fortran programs, disagree about the
-meaning of such invocations.
-
-The first version of @code{JCB002} didn't accommodate some compilers'
-treatment of @samp{INT(I1-I2)} where @samp{I1} and @samp{I2} are
-@code{INTEGER*2}.
-In such a case, these compilers apparently convert both
-operands to @code{INTEGER*4} and then do an @code{INTEGER*4} subtraction,
-instead of doing an @code{INTEGER*2} subtraction on the
-original values in @samp{I1} and @samp{I2}.
-
-However, the results of the careful analyses done on the outputs
-of programs compiled by these various compilers show that they
-all implement either @samp{Interp 1} or @samp{Interp 2} above.
-
-Specifically, it is believed that the new version of @code{JCB002}
-above will confirm that:
-

-
-In accordance with Fortran 90 and at least some (perhaps all)
-other compilers, the GNU Fortran language defines @code{CMPLX()}
-as always returning a result that is type @code{COMPLEX(KIND=1)}.
-
-This means @samp{CMPLX(D1,D2)}, where @samp{D1} and @samp{D2}
-are @code{REAL(KIND=2)} (@code{DOUBLE PRECISION}), is treated as:
-
-@example
-CMPLX(SNGL(D1), SNGL(D2))
-@end example
-
-(It was necessary for Fortran 90 to specify this behavior
-for @code{DOUBLE PRECISION} arguments, since that is
-the behavior mandated by FORTRAN 77.)
-
-The GNU Fortran language also provides the @code{DCMPLX()} intrinsic,
-which is provided by some FORTRAN 77 compilers to construct
-a @code{DOUBLE COMPLEX} entity from of @code{DOUBLE PRECISION}
-operands.
-However, this solution does not scale well when more @code{COMPLEX} types
-(having various precisions and ranges) are offered by Fortran implementations.
-
-Fortran 90 extends the @code{CMPLX()} intrinsic by adding
-an extra argument used to specify the desired kind of complex
-result.
-However, this solution is somewhat awkward to use, and
-@command{g77} currently does not support it.
-
-The GNU Fortran language provides a simple way to build a complex
-value out of two numbers, with the precise type of the value
-determined by the types of the two numbers (via the usual
-type-promotion mechanism):
-
-@example
-COMPLEX(@var{real}, @var{imag})

-
-When @var{real} and @var{imag} are the same @code{REAL} types, @code{COMPLEX()}
-performs no conversion other than to put them together to form a

-The GNU Fortran language adds various functions, subroutines, types,

-The complete set of intrinsics supported by the GNU Fortran language
-is described below.
-
-Note that a name is not treated as that of an intrinsic if it is

-the intrinsic belongs; or if the intrinsic is not named in an
-@code{INTRINSIC} statement and a command-line option is used to
-hide the groups to which the intrinsic belongs.
-
-So, it is recommended that any reference in a program unit to
-an intrinsic procedure that is not a standard FORTRAN 77
-intrinsic be accompanied by an appropriate @code{INTRINSIC}
-statement in that program unit.
-This sort of defensive programming makes it more
-likely that an implementation will issue a diagnostic rather

-be a variable or array element, or perhaps a constant if expressions
-are permitted).
-
-@item
-@samp{DIMENSION(4)} means the argument must be an array having 4 elements.
-

-@code{INTENT(IN)} means the argument must be an expression
-(such as a constant or a variable that is defined upon invocation
-of the intrinsic).
-

-
-GNU Fortran accepts programs written in either fixed form or
-free form.
-
-Fixed form
-corresponds to ANSI FORTRAN 77 (plus popular extensions, such as
-allowing tabs) and Fortran 90's fixed form.
-
-Free form corresponds to
-Fortran 90's free form (though possibly not entirely up-to-date, and
-without complaining about some things that for which Fortran 90 requires
-diagnostics, such as the spaces in the constant in @samp{R = 3 . 1}).
-
-The way a Fortran compiler views source files depends entirely on the
-implementation choices made for the compiler, since those choices
-are explicitly left to the implementation by the published Fortran
-standards.
-GNU Fortran currently tries to be somewhat like a few popular compilers
-(@command{f2c}, Digital (``DEC'') Fortran, and so on).

-@subsection Carriage Returns
-@cindex carriage returns
-
-Carriage returns (@samp{\r}) in source lines are ignored.

-inside such constants.
-
-@node Tabs
-@subsection Tabs
-@cindex tab character
-@cindex horizontal tab
-
-A source line with a @key{TAB} character anywhere in it is treated as
-entirely significant---however long it is---instead of ending in
-column 72 (for fixed-form source) or 132 (for free-form source).
-This also is different from @command{f2c}, which encodes tabs as
-@samp{\t} (the ASCII @key{TAB} character) inside character
-and Hollerith constants, but nevertheless seems to treat the column
-position as if it had been affected by the canonical tab positioning.
-
-@command{g77} effectively
-translates tabs to the appropriate number of spaces (a la the default
-for the UNIX @command{expand} command) before doing any other processing, other
-than (currently) noting whether a tab was found on a line and using this
-information to decide how to interpret the length of the line and continued
-constants.

-@subsection Short Lines
-@cindex short source lines

-@cindex lines, short
-
-Source lines shorter than the applicable fixed-form length are treated as
-if they were padded with spaces to that length.
-(None of this is relevant to source files written in free form.)
-
-This affects only
-continued character and Hollerith constants, and is a different
-interpretation than provided by some other popular compilers
-(although a bit more consistent with the traditional punched-card
-basis of Fortran and the way the Fortran standard expressed fixed
-source form).
-
-@command{g77} might someday offer an option to warn about cases where differences
-might be seen as a result of this treatment, and perhaps an option to
-specify the alternate behavior as well.
-
-Note that this padding cannot apply to lines that are effectively of

-In the GNU Fortran language, @samp{!} is used for this purpose.
-
-@samp{/*} is not in the GNU Fortran language

-since that is the meaning of @samp{/*} in C.
-
-Also, such readers might think they can use @samp{//} to start

-GNU Fortran offers the programmer way too much flexibility in deciding
-how source files are to be treated vis-a-vis uppercase and lowercase
-characters.
-There are 66 useful settings that affect case sensitivity, plus 10
-settings that are nearly useless, with the remaining 116 settings
-being either redundant or useless.
-
-None of these settings have any effect on the contents of comments
-(the text after a @samp{c} or @samp{C} in Column 1, for example)
-or of character or Hollerith constants.
-Note that things like the @samp{E} in the statement
-@samp{CALL FOO(3.2E10)} and the @samp{TO} in @samp{ASSIGN 10 TO LAB}
-are considered built-in keywords, and so are affected by
-these settings.
-
-Low-level switches are identified in this section as follows:
-
-@itemize @w{}
-@item A
-Source Case Conversion:
-
-@itemize @w{}
-@item 0
-Preserve (see Note 1)
-@item 1
-Convert to Upper Case
-@item 2
-Convert to Lower Case
-@end itemize

-@item 1
-Allow Upper Case Only
-@item 2
-Allow Lower Case Only
-@item 3
-Allow InitialCaps Only (see Note 2)
-@end itemize
-@end itemize
-
-Note 1: @command{g77} eventually will support @code{NAMELIST} in a manner that is
-consistent with these source switches---in the sense that input will be
-expected to meet the same requirements as source code in terms
-of matching symbol names and keywords (for the exponent letters).
-
-Currently, however, @code{NAMELIST} is supported by @code{libg2c},
-which uppercases @code{NAMELIST} input and symbol names for matching.
-This means not only that @code{NAMELIST} output currently shows symbol
-(and keyword) names in uppercase even if lower-case source
-conversion (option A2) is selected, but that @code{NAMELIST} cannot be
-adequately supported when source case preservation (option A0)
-is selected.
-
-If A0 is selected, a warning message will be
-output for each @code{NAMELIST} statement to this effect.
-The behavior
-of the program is undefined at run time if two or more symbol names
-appear in a given @code{NAMELIST} such that the names are identical
-when converted to upper case (e.g. @samp{NAMELIST /X/ VAR, Var, var}).
-For complete and total elegance, perhaps there should be a warning
-when option A2 is selected, since the output of NAMELIST is currently
-in uppercase but will someday be lowercase (when a @code{libg77} is written),
-but that seems to be overkill for a product in beta test.
-
-Note 2: Rules for InitialCaps names are:
-
-@itemize @minus
-@item
-Must be a single uppercase letter, @strong{or}
-@item
-Must start with an uppercase letter and contain at least one
-lowercase letter.
-@end itemize
-
-So @samp{A}, @samp{Ab}, @samp{ABc}, @samp{AbC}, and @samp{Abc} are
-valid InitialCaps names, but @samp{AB}, @samp{A2}, and @samp{ABC} are
-not.
-Note that most, but not all, built-in names meet these
-requirements---the exceptions are some of the two-letter format
-specifiers, such as @code{BN} and @code{BZ}.
-
-Here are the names of the corresponding command-line options:

-someday, and is considered a VXT Fortran feature.

-in GNU Fortran and another in VXT Fortran), the VXT Fortran

-So, the purpose of @option{-ff90} is not to specify whether @command{g77} is

-The @option{-pedantic} option specified with @option{-fno-f90} is intended

-and thus is not a dummy argument.

-@item
-The commas in @samp{READ (5), I} and @samp{WRITE (10), J}.

-These commas are disallowed by FORTRAN 77, but, while strictly
-superfluous, are syntactically elegant,
-especially given that commas are required in statements such
-as @samp{READ 99, I} and @samp{PRINT *, J}.
-Many compilers permit the superfluous commas for this reason.
-
-@item
-@code{DOUBLE COMPLEX}, either explicitly or implicitly.
-
-An explicit use of this type is via a @code{DOUBLE COMPLEX} or
-@code{IMPLICIT DOUBLE COMPLEX} statement, for examples.
-
-An example of an implicit use is the expression @samp{C*D},
-where @samp{C} is @code{COMPLEX(KIND=1)}
-and @samp{D} is @code{DOUBLE PRECISION}.
-This expression is prohibited by ANSI FORTRAN 77
-because the rules of promotion would suggest that it

-@cindex arrays, assumed-size
-@cindex assumed-size arrays
-@cindex DIMENSION X(1)
-
-The @option{-fugly-assumed} option enables
-the treatment of any array with a final dimension specified as @samp{1}
-as an assumed-size array, as if @samp{*} had been specified
-instead.
-
-For example, @samp{DIMENSION X(1)} is treated as if it
-had read @samp{DIMENSION X(*)} if @samp{X} is listed as
-a dummy argument in a preceding @code{SUBROUTINE}, @code{FUNCTION},
-or @code{ENTRY} statement in the same program unit.
-
-Use an explicit lower bound to avoid this interpretation.
-For example, @samp{DIMENSION X(1:1)} is never treated as if
-it had read @samp{DIMENSION X(*)} or @samp{DIMENSION X(1:*)}.
-Nor is @samp{DIMENSION X(2-1)} affected by this option,
-since that kind of expression is unlikely to have been
-intended to designate an assumed-size array.
-
-This option is used to prevent warnings being issued about apparent
-out-of-bounds reference such as @samp{X(2) = 99}.
-
-It also prevents the array from being used in contexts that
-disallow assumed-size arrays, such as @samp{PRINT *,X}.
-In such cases, a diagnostic is generated and the source file is
-not compiled.
-
-The construct affected by this option is used only in old code
-that pre-exists the widespread acceptance of adjustable and assumed-size
-arrays in the Fortran community.
-
-@emph{Note:} This option does not affect how @samp{DIMENSION X(1)} is
-treated if @samp{X} is listed as a dummy argument only
-@emph{after} the @code{DIMENSION} statement (presumably in
-an @code{ENTRY} statement).
-For example, @option{-fugly-assumed} has no effect on the
-following program unit:
-
-@example
-SUBROUTINE X
-REAL A(1)
-RETURN
-ENTRY Y(A)
-PRINT *, A

-The @option{-fugly-complex} option enables

-intrinsics with arguments that are
-@code{COMPLEX} types other than @code{COMPLEX(KIND=1)}.
-
-With @option{-ff90} in effect, these intrinsics return
-the unconverted real and imaginary parts (respectively)
-of their argument.
-
-With @option{-fno-f90} in effect, these intrinsics convert
-the real and imaginary parts to @code{REAL(KIND=1)}, and return
-the result of that conversion.
-
-Due to this ambiguity, the GNU Fortran language defines
-these constructs as invalid, except in the specific
-case where they are entirely and solely passed as an
-argument to an invocation of the @code{REAL()} intrinsic.
-For example,
-
-@example
-REAL(REAL(Z))

-
-@noindent
-is permitted even when @samp{Z} is @code{COMPLEX(KIND=2)}
-and @option{-fno-ugly-complex} is in effect, because the

-The @option{-fugly-comma} option enables use of a single trailing comma

-and use of an empty list of arguments to such a procedure
-to mean ``pass a single null argument''.
-
-@cindex omitting arguments
-@cindex arguments, omitting
-(Null arguments often are used in some procedure-calling
-schemes to indicate omitted arguments.)
-
-For example, @samp{CALL FOO(,)} means ``pass
-two null arguments'', rather than ``pass one null argument''.
-Also, @samp{CALL BAR()} means ``pass one null argument''.
-
-This construct is considered ``ugly'' because it does not
-provide an elegant way to pass a single null argument
-that is syntactically distinct from passing no arguments.
-That is, this construct changes the meaning of code that
-makes no use of the construct.
-
-So, with @option{-fugly-comma} in force, @samp{CALL FOO()}
-and @samp{I = JFUNC()} pass a single null argument, instead
-of passing no arguments as required by the Fortran 77 and
-90 standards.
-
-@emph{Note:} Many systems gracefully allow the case
-where a procedure call passes one extra argument that the
-called procedure does not expect.
-
-So, in practice, there might be no difference in
-the behavior of a program that does @samp{CALL FOO()}
-or @samp{I = JFUNC()} and is compiled with @option{-fugly-comma}
-in force as compared to its behavior when compiled
-with the default, @option{-fno-ugly-comma}, in force,

-The above constructs are disabled by default because use

-
-Some of this is due to differences among implementations as

-@node Ugly Assigned Labels
-@subsection Ugly Assigned Labels
-@cindex ASSIGN statement

-@cindex assigned labels

-
-The @option{-fugly-assign} option forces @command{g77} to use the
-same storage for assigned labels as it would for a normal
-assignment to the same variable.
-
-For example, consider the following code fragment:
-
-@example
-I = 3
-ASSIGN 10 TO I
-@end example
-
-@noindent
-Normally, for portability and improved diagnostics, @command{g77}
-reserves distinct storage for a ``sibling'' of @samp{I}, used
-only for @code{ASSIGN} statements to that variable (along with
-the corresponding assigned-@code{GOTO} and assigned-@code{FORMAT}-I/O
-statements that reference the variable).
-
-However, some code (that violates the ANSI FORTRAN 77 standard)
-attempts to copy assigned labels among variables involved with
-@code{ASSIGN} statements, as in:
-
-@example
-ASSIGN 10 TO I
-ISTATE(5) = I
-@dots{}
-J = ISTATE(ICUR)
-GOTO J
-@end example
-
-@noindent
-Such code doesn't work under @command{g77} unless @option{-fugly-assign}
-is specified on the command-line, ensuring that the value of @code{I}
-referenced in the second line is whatever value @command{g77} uses
-to designate statement label @samp{10}, so the value may be
-copied into the @samp{ISTATE} array, later retrieved into a
-variable of the appropriate type (@samp{J}), and used as the target of
-an assigned-@code{GOTO} statement.
-
-@emph{Note:} To avoid subtle program bugs,
-when @option{-fugly-assign} is specified,
-@command{g77} requires the type of variables
-specified in assigned-label contexts
-@emph{must} be the same type returned by @code{%LOC()}.
-On many systems, this type is effectively the same
-as @code{INTEGER(KIND=1)}, while, on others, it is
-effectively the same as @code{INTEGER(KIND=2)}.

-@section Run-time Environment Limits
-@cindex limits, run-time library
-@cindex wraparound
-
-As a portable Fortran implementation,
-@command{g77} offers its users direct access to,
-and otherwise depends upon,
-the underlying facilities of the system
-used to build @command{g77},
-the system on which @command{g77} itself is used to compile programs,
-and the system on which the @command{g77}-compiled program is actually run.
-(For most users, the three systems are of the same
-type---combination of operating environment and hardware---often
-the same physical system.)
-
-The run-time environment for a particular system
-inevitably imposes some limits on a program's use
-of various system facilities.
-These limits vary from system to system.
-
-Even when such limits might be well beyond the
-possibility of being encountered on a particular system,
-the @command{g77} run-time environment
-has certain built-in limits,
-usually, but not always, stemming from intrinsics
-with inherently limited interfaces.
-
-Currently, the @command{g77} run-time environment
-does not generally offer a less-limiting environment
-by augmenting the underlying system's own environment.
-
-Therefore, code written in the GNU Fortran language,
-while syntactically and semantically portable,
-might nevertheless make non-portable assumptions
-about the run-time environment---assumptions that
-prove to be false for some particular environments.
-
-The GNU Fortran language,
-the @command{g77} compiler and run-time environment,
-and the @command{g77} documentation
-do not yet offer comprehensive portable work-arounds for such limits,
-though programmers should be able to
-find their own in specific instances.
-
-Not all of the limitations are described in this document.

-@cindex Y2K compliance
-@cindex Year 2000 compliance
-
-While the @command{g77} compiler itself is believed to
-be Year-2000 (Y2K) compliant,
-some intrinsics are not,
-and, potentially, some underlying systems are not,
-perhaps rendering some Y2K-compliant intrinsics
-non-compliant when used on those particular systems.
-
-Fortran code that uses non-Y2K-compliant intrinsics
-(listed below)
-is, itself, almost certainly not compliant,
-and should be modified to use Y2K-compliant intrinsics instead.
-
-Fortran code that uses no non-Y2K-compliant intrinsics,
-but which currently is running on a non-Y2K-compliant system,
-can be made more Y2K compliant by compiling and
-linking it for use on a new Y2K-compliant system,
-such as a new version of an old, non-Y2K-compliant, system.
-
-Currently, information on Y2K and related issues
-is being maintained at
-@uref{http://www.gnu.org/software/year2000-list.html}.

-@cindex vxtidate_y2kbuggy_0
-@cindex G77_date_y2kbuggy_0
-@cindex G77_vxtidate_y2kbuggy_0
-The @code{libg2c} library
-shipped with any @command{g77} that warns
-about invocation of a non-Y2K-compliant intrinsic
-has renamed the @code{EXTERNAL} procedure names
-of those intrinsics.
-This is done so that
-the @code{libg2c} implementations of these intrinsics
-cannot be directly linked to
-as @code{EXTERNAL} names
-(which normally would avoid the non-Y2K-intrinsic warning).
-
-The renamed forms of the @code{EXTERNAL} names
-of these renamed procedures
-may be linked to
-by appending the string @samp{_y2kbug}
-to the name of the procedure
-in the source code.
-For example:
-
-@smallexample
-CHARACTER*20 STR
-INTEGER YY, MM, DD
-EXTERNAL DATE_Y2KBUG, VXTIDATE_Y2KBUG
-CALL DATE_Y2KBUG (STR)
-CALL VXTIDATE_Y2KBUG (MM, DD, YY)
-@end smallexample
-
-(Note that the @code{EXTERNAL} statement
-is not actually required,
-since the modified names are not recognized as intrinsics
-by the current version of @command{g77}.
-But it is shown in this specific case,
-for purposes of illustration.)
-
-The renaming of @code{EXTERNAL} procedure names of these intrinsics
-causes unresolved references at link time.
-For example, @samp{EXTERNAL DATE; CALL DATE(STR)}
-is normally compiled by @command{g77}
-as, in C, @samp{date_(&str, 20);}.
-This, in turn, links to the @code{date_} procedure
-in the @code{libE77} portion of @code{libg2c},
-which purposely calls a nonexistent procedure
-named @code{G77_date_y2kbuggy_0}.
-The resulting link-time error is designed, via this name,
-to encourage the programmer to look up the
-index entries to this portion of the @command{g77} documentation.
-
-Generally, we recommend that the @code{EXTERNAL} method
-of invoking procedures in @code{libg2c}
-@emph{not} be used.
-When used, some of the correctness checking
-normally performed by @command{g77}
-is skipped.
-
-In particular, it is probably better to use the
-@code{INTRINSIC} method of invoking
-non-Y2K-compliant procedures,
-so anyone compiling the code
-can quickly notice the potential Y2K problems
-(via the warnings printing by @command{g77})
-without having to even look at the code itself.
-
-If there are problems linking @code{libg2c}
-to code compiled by @command{g77}
-that involve the string @samp{y2kbug},
-and these are not explained above,
-that probably indicates
-that a version of @code{libg2c}
-older than @command{g77}
-is being linked to,
-or that the new library is being linked
-to code compiled by an older version of @command{g77}.
-
-That's because, as of the version that warns about
-non-Y2K-compliant intrinsic invocation,
-@command{g77} references the @code{libg2c} implementations
-of those intrinsics
-using new names, containing the string @samp{y2kbug}.
-
-So, linking newly-compiled code
-(invoking one of the intrinsics in question)
-to an old library
-might yield an unresolved reference
-to @code{G77_date_y2kbug_0}.
-(The old library calls it @code{G77_date_0}.)
-
-Similarly, linking previously-compiled code
-to a new library
-might yield an unresolved reference
-to @code{G77_vxtidate_0}.
-(The new library calls it @code{G77_vxtidate_y2kbug_0}.)
-
-The proper fix for the above problems
-is to obtain the latest release of @command{g77}
-and related products
-(including @code{libg2c})
-and install them on all systems,
-then recompile, relink, and install
-(as appropriate)
-all existing Fortran programs.
-
-(Normally, this sort of renaming is steadfastly avoided.
-In this case, however, it seems more important to highlight
-potential Y2K problems
-than to ease the transition
-of potentially non-Y2K-compliant code
-to new versions of @command{g77} and @code{libg2c}.)

-@cindex types, of data
-@cindex data types
-
-Fortran implementations have a fair amount of freedom given them by the
-standard as far as how much storage space is used and how much precision
-and range is offered by the various types such as @code{LOGICAL(KIND=1)},
-@code{INTEGER(KIND=1)}, @code{REAL(KIND=1)}, @code{REAL(KIND=2)},
-@code{COMPLEX(KIND=1)}, and @code{CHARACTER}.
-Further, many compilers offer so-called @samp{*@var{n}} notation, but
-the interpretation of @var{n} varies across compilers and target architectures.
-
-The standard requires that @code{LOGICAL(KIND=1)}, @code{INTEGER(KIND=1)},
-and @code{REAL(KIND=1)}
-occupy the same amount of storage space, and that @code{COMPLEX(KIND=1)}
-and @code{REAL(KIND=2)} take twice as much storage space as @code{REAL(KIND=1)}.
-Further, it requires that @code{COMPLEX(KIND=1)}
-entities be ordered such that when a @code{COMPLEX(KIND=1)} variable is
-storage-associated (such as via @code{EQUIVALENCE})
-with a two-element @code{REAL(KIND=1)} array named @samp{R}, @samp{R(1)}
-corresponds to the real element and @samp{R(2)} to the imaginary
-element of the @code{COMPLEX(KIND=1)} variable.
-
-(Few requirements as to precision or ranges of any of these are
-placed on the implementation, nor is the relationship of storage sizes of
-these types to the @code{CHARACTER} type specified, by the standard.)
-
-@command{g77} follows the above requirements, warning when compiling
-a program requires placement of items in memory that contradict the
-requirements of the target architecture.
-(For example, a program can require placement of a @code{REAL(KIND=2)}
-on a boundary that is not an even multiple of its size, but still an
-even multiple of the size of a @code{REAL(KIND=1)} variable.
-On some target architectures, using the canonical
-mapping of Fortran types to underlying architectural types, such
-placement is prohibited by the machine definition or
-the Application Binary Interface (ABI) in force for
-the configuration defined for building @command{gcc} and @command{g77}.
-@command{g77} warns about such
-situations when it encounters them.)
-
-@command{g77} follows consistent rules for configuring the mapping between Fortran

-These rules offer a widely portable, consistent Fortran/C
-environment, although they might well conflict with the expectations of

-
-These rules are based on the configuration that is in force for the

-@cindex groups of intrinsics
-@cindex intrinsics, groups
-
-A given specific intrinsic belongs in one or more groups.

-by default or a command-line option.
-The meaning of each term follows.
-
-@table @b
-@cindex deleted intrinsics
-@cindex intrinsics, deleted
-@item Deleted
-No intrinsics are recognized as belonging to that group.
-
-@cindex disabled intrinsics
-@cindex intrinsics, disabled
-@item Disabled
-Intrinsics are recognized as belonging to the group, but
-references to them (other than via the @code{INTRINSIC} statement)
-are disallowed through that group.
-
-@cindex hidden intrinsics
-@cindex intrinsics, hidden
-@item Hidden
-Intrinsics in that group are recognized and enabled (if implemented)
-@emph{only} if the first mention of the actual name of an intrinsic
-in a program unit is in an @code{INTRINSIC} statement.
-
-@cindex enabled intrinsics
-@cindex intrinsics, enabled
-@item Enabled
-Intrinsics in that group are recognized and enabled (if implemented).
-@end table
-
-The distinction between deleting and disabling a group is illustrated
-by the following example.
-Assume intrinsic @samp{FOO} belongs only to group @samp{FGR}.
-If group @samp{FGR} is deleted, the following program unit will
-successfully compile, because @samp{FOO()} will be seen as a
-reference to an external function named @samp{FOO}:
-
-@example
-PRINT *, FOO()
-END
-@end example
-
-@noindent
-If group @samp{FGR} is disabled, compiling the above program will produce
-diagnostics, either because the @samp{FOO} intrinsic is improperly invoked
-or, if properly invoked, it is not enabled.
-To change the above program so it references an external function @samp{FOO}
-instead of the disabled @samp{FOO} intrinsic,
-add the following line to the top:
-
-@example
-EXTERNAL FOO
-@end example
-
-@noindent
-So, deleting a group tells @command{g77} to pretend as though the intrinsics in
-that group do not exist at all, whereas disabling it tells @command{g77} to
-recognize them as (disabled) intrinsics in intrinsic-like contexts.
-
-Hiding a group is like enabling it, but the intrinsic must be first
-named in an @code{INTRINSIC} statement to be considered a reference to the
-intrinsic rather than to an external procedure.
-This might be the ``safest'' way to treat a new group of intrinsics
-when compiling old
-code, because it allows the old code to be generally written as if
-those new intrinsics never existed, but to be changed to use them
-by inserting @code{INTRINSIC} statements in the appropriate places.
-However, it should be the goal of development to use @code{EXTERNAL}
-for all names of external procedures that might be intrinsic names.
-
-If an intrinsic is in more than one group, it is enabled if any of its
-containing groups are enabled; if not so enabled, it is hidden if
-any of its containing groups are hidden; if not so hidden, it is disabled
-if any of its containing groups are disabled; if not so disabled, it is
-deleted.
-This extra complication is necessary because some intrinsics,
-such as @code{IBITS}, belong to more than one group, and hence should be
-enabled if any of the groups to which they belong are enabled, and so
-on.

-@chapter Other Compilers
-
-An individual Fortran source file can be compiled to
-an object (@file{*.o}) file instead of to the final
-program executable.
-This allows several portions of a program to be compiled
-at different times and linked together whenever a new
-version of the program is needed.
-However, it introduces the issue of @dfn{object compatibility}
-across the various object files (and libraries, or @file{*.a}
-files) that are linked together to produce any particular
-executable file.
-
-Object compatibility is an issue when combining, in one
-program, Fortran code compiled by more than one compiler
-(or more than one configuration of a compiler).
-If the compilers
-disagree on how to transform the names of procedures, there
-will normally be errors when linking such programs.
-Worse, if the compilers agree on naming, but disagree on issues
-like how to pass parameters, return arguments, and lay out
-@code{COMMON} areas, the earliest detected errors might be the
-incorrect results produced by the program (and that assumes
-these errors are detected, which is not always the case).
-
-Normally, @command{g77} generates code that is
-object-compatible with code generated by a version of
-@command{f2c} configured (with, for example, @file{f2c.h} definitions)
-to be generally compatible with @command{g77} as built by @command{gcc}.
-(Normally, @command{f2c} will, by default, conform to the appropriate
-configuration, but it is possible that older or perhaps even newer
-versions of @command{f2c}, or versions having certain configuration changes
-to @command{f2c} internals, will produce object files that are
-incompatible with @command{g77}.)
-
-For example, a Fortran string subroutine
-argument will become two arguments on the C side: a @code{char *}
-and an @code{int} length.
-
-Much of this compatibility results from the fact that
-@command{g77} uses the same run-time library,
-@code{libf2c}, used by @command{f2c},
-though @command{g77} gives its version the name @code{libg2c}
-so as to avoid conflicts when linking,
-installing them in the same directories,
-and so on.
-
-Other compilers might or might not generate code that
-is object-compatible with @code{libg2c} and current @command{g77},
-and some might offer such compatibility only when explicitly
-selected via a command-line option to the compiler.

-@node Dropping f2c Compatibility
-@section Dropping @command{f2c} Compatibility
-
-Specifying @option{-fno-f2c} allows @command{g77} to generate, in
-some cases, faster code, by not needing to allow to the possibility
-of linking with code compiled by @command{f2c}.
-
-For example, this affects how @code{REAL(KIND=1)},
-@code{COMPLEX(KIND=1)}, and @code{COMPLEX(KIND=2)} functions are called.
-With @option{-fno-f2c}, they are
-compiled as returning the appropriate @command{gcc} type
-(@code{float}, @code{__complex__ float}, @code{__complex__ double},
-in many configurations).
-
-With @option{-ff2c} in force, they
-are compiled differently (with perhaps slower run-time performance)
-to accommodate the restrictions inherent in @command{f2c}'s use of K&R
-C as an intermediate language---@code{REAL(KIND=1)} functions
-return C's @code{double} type, while @code{COMPLEX} functions return
-@code{void} and use an extra argument pointing to a place for the functions to
-return their values.
-
-It is possible that, in some cases, leaving @option{-ff2c} in force
-might produce faster code than using @option{-fno-f2c}.
-Feel free to experiment, but remember to experiment with changing the way
-@emph{entire programs and their Fortran libraries are compiled} at
-a time, since this sort of experimentation affects the interface
-of code generated for a Fortran source file---that is, it affects
-object compatibility.
-
-Note that @command{f2c} compatibility is a fairly static target to achieve,
-though not necessarily perfectly so, since, like @command{g77}, it is
-still being improved.
-However, specifying @option{-fno-f2c} causes @command{g77}
-to generate code that will probably be incompatible with code
-generated by future versions of @command{g77} when the same option
-is in force.
-You should make sure you are always able to recompile complete
-programs from source code when upgrading to new versions of @command{g77}
-or @command{f2c}, especially when using options such as @option{-fno-f2c}.
-
-Therefore, if you are using @command{g77} to compile libraries and other
-object files for possible future use and you don't want to require
-recompilation for future use with subsequent versions of @command{g77},
-you might want to stick with @command{f2c} compatibility for now, and
-carefully watch for any announcements about changes to the
-@command{f2c}/@code{libf2c} interface that might affect existing programs
-(thus requiring recompilation).
-
-It is probable that a future version of @command{g77} will not,
-by default, generate object files compatible with @command{f2c},
-and that version probably would no longer use @code{libf2c}.
-If you expect to depend on this compatibility in the
-long term, use the options @samp{-ff2c -ff2c-library} when compiling
-all of the applicable code.
-This should cause future versions of @command{g77} either to produce
-compatible code (at the expense of the availability of some features and
-performance), or at the very least, to produce diagnostics.
-
-(The library @command{g77} produces will no longer be named @file{libg2c}
-when it is no longer generally compatible with @file{libf2c}.
-It will likely be referred to, and, if installed as a distinct
-library, named @code{libg77}, or some other as-yet-unused name.)
-
-@node Compilers Other Than f2c
-@section Compilers Other Than @command{f2c}
-
-On systems with Fortran compilers other than @command{f2c} and @command{g77},
-code compiled by @command{g77} is not expected to work
-well with code compiled by the native compiler.
-(This is true for @command{f2c}-compiled objects as well.)
-Libraries compiled with the native compiler probably will have
-to be recompiled with @command{g77} to be used with @command{g77}-compiled code.
-
-Reasons for such incompatibilities include:
-
-@itemize @bullet
-@item
-There might be differences in the way names of Fortran procedures
-are translated for use in the system's object-file format.
-For example, the statement @samp{CALL FOO} might be compiled
-by @command{g77} to call a procedure the linker @command{ld} sees
-given the name @samp{_foo_}, while the apparently corresponding
-statement @samp{SUBROUTINE FOO} might be compiled by the
-native compiler to define the linker-visible name @samp{_foo},
-or @samp{_FOO_}, and so on.
-
-@item
-There might be subtle type mismatches which cause subroutine arguments
-and function return values to get corrupted.
-
-This is why simply getting @command{g77} to
-transform procedure names the same way a native
-compiler does is not usually a good idea---unless
-some effort has been made to ensure that, aside
-from the way the two compilers transform procedure
-names, everything else about the way they generate
-code for procedure interfaces is identical.
-
-@item
-Native compilers
-use libraries of private I/O routines which will not be available
-at link time unless you have the native compiler---and you would
-have to explicitly ask for them.
-
-For example, on the Sun you
-would have to add @samp{-L/usr/lang/SCx.x -lF77 -lV77} to the link
-command.

-A simple and foolproof way to write @command{g77}-callable C routines---e.g.@: to

-skeletons comprising just the declaration of the routine(s) and dummy

-Then run @command{f2c} on file @file{fred.f} to produce @file{fred.c}

-So, use an @samp{extern "C"} declaration.

-@cindex initialization, run-time
-Unlike with some runtime systems,
-it shouldn't be necessary
-(unless there are bugs)
-to use a Fortran main program unit to ensure the
-runtime---specifically the I/O system---is initialized.
-
-However, to use the @command{g77} intrinsics @code{GETARG} and @code{IARGC},
-either the @code{main} routine from the @file{libg2c} library must be used,
-or the @code{f_setarg} routine
-(new as of @code{egcs} version 1.1 and @command{g77} version 0.5.23)
-must be called with the appropriate @code{argc} and @code{argv} arguments
-prior to the program calling @code{GETARG} or @code{IARGC}.
-
-To provide more flexibility for mixed-language programming
-involving @command{g77} while allowing for shared libraries,
-as of @code{egcs} version 1.1 and @command{g77} version 0.5.23,
-@command{g77}'s @code{main} routine in @code{libg2c}
-does the following, in order:
-
-@enumerate
-@item
-Calls @code{f_setarg}
-with the incoming @code{argc} and @code{argv} arguments,
-in the same order as for @code{main} itself.
-
-This sets up the command-line environment
-for @code{GETARG} and @code{IARGC}.
-
-@item
-Calls @code{f_setsig} (with no arguments).
-
-This sets up the signaling and exception environment.
-
-@item
-Calls @code{f_init} (with no arguments).
-
-This initializes the I/O environment,
-though that should not be necessary,
-as all I/O functions in @code{libf2c}
-are believed to call @code{f_init} automatically,
-if necessary.
-
-(A future version of @command{g77} might skip this explicit step,
-to speed up normal exit of a program.)
-
-@item
-Arranges for @code{f_exit} to be called (with no arguments)
-when the program exits.
-
-This ensures that the I/O environment is properly shut down
-before the program exits normally.
-Otherwise, output buffers might not be fully flushed,
-scratch files might not be deleted, and so on.
-
-The simple way @code{main} does this is
-to call @code{f_exit} itself after calling

-
-However, this does not catch the cases where the program
-might call @code{exit} directly,
-instead of using the @code{EXIT} intrinsic
-(implemented as @code{exit_} in @code{libf2c}).
-
-So, @code{main} attempts to use
-the operating environment's @code{onexit} or @code{atexit}
-facility, if available,
-to cause @code{f_exit} to be called automatically
-upon any invocation of @code{exit}.
-
-@item
-Calls @code{MAIN__} (with no arguments).
-
-This starts executing the Fortran main program unit for
-the application.
-(Both @command{g77} and @command{f2c} currently compile a main
-program unit so that its global name is @code{MAIN__}.)
-
-@item
-If no @code{onexit} or @code{atexit} is provided by the system,
-calls @code{f_exit}.
-
-@item
-Calls @code{exit} with a zero argument,

-

-
-When using the @code{main} procedure provided by @command{g77}
-without a Fortran main program unit,
-you need to provide @code{MAIN__}
-as the entry point for your C code.
-(Make sure you link the object file that defines that
-entry point with the rest of your program.)
-
-To provide your own @code{main} procedure
-in place of @command{g77}'s,
-make sure you specify the object file defining that procedure
-@emph{before} @option{-lg2c} on the @command{g77} command line.
-Since the @option{-lg2c} option is implicitly provided,
-this is usually straightforward.
-(Use the @option{--verbose} option to see how and where
-@command{g77} implicitly adds @option{-lg2c} in a command line
-that will link the program.
-Feel free to specify @option{-lg2c} explicitly,
-as appropriate.)
-
-However, when providing your own @code{main},
-make sure you perform the appropriate tasks in the
-appropriate order.
-For example, if your @code{main} does not call @code{f_setarg},
-make sure the rest of your application does not call
-@code{GETARG} or @code{IARGC}.
-
-And, if your @code{main} fails to ensure that @code{f_exit}
-is called upon program exit,
-some files might end up incompletely written,
-some scratch files might be left lying around,
-and some existing files being written might be left
-with old data not properly truncated at the end.
-
-Note that, generally, the @command{g77} operating environment
-does not depend on a procedure named @code{MAIN__} actually
-being called prior to any other @command{g77}-compiled code.
-That is, @code{MAIN__} does not, itself,
-set up any important operating-environment characteristics
-upon which other code might depend.
-This might change in future versions of @command{g77},

-
-GNU Fortran currently generates code that is object-compatible with
-the @command{f2c} converter.
-Also, it avoids limitations in the current GBE, such as the
-inability to generate a procedure with
-multiple entry points, by generating code that is structured
-differently (in terms of procedure names, scopes, arguments, and
-so on) than might be expected.
-
-As a result, writing code in other languages that calls on, is
-called by, or shares in-memory data with @command{g77}-compiled code generally
-requires some understanding of the way @command{g77} compiles code for
-various constructs.
-
-Similarly, using a debugger to debug @command{g77}-compiled
-code, even if that debugger supports native Fortran debugging, generally
-requires this sort of information.
-
-This section describes some of the basic information on how
-@command{g77} compiles code for constructs involving interfaces to other
-languages and to debuggers.
-
-@emph{Caution:} Much or all of this information pertains to only the current
-release of @command{g77}, sometimes even to using certain compiler options
-with @command{g77} (such as @option{-fno-f2c}).
-Do not write code that depends on this
-information without clearly marking said code as nonportable and
-subject to review for every new release of @command{g77}.
-This information
-is provided primarily to make debugging of code generated by this
-particular release of @command{g77} easier for the user, and partly to make
-writing (generally nonportable) interface code easier.
-Both of these
-activities require tracking changes in new version of @command{g77} as they
-are installed, because new versions can change the behaviors

-@section Main Program Unit (PROGRAM)
-@cindex PROGRAM statement
-@cindex statements, PROGRAM
-
-When @command{g77} compiles a main program unit, it gives it the public
-procedure name @code{MAIN__}.
-The @code{libg2c} library has the actual @code{main()} procedure
-as is typical of C-based environments, and
-it is this procedure that performs some initial start-up
-activity and then calls @code{MAIN__}.
-
-Generally, @command{g77} and @code{libg2c} are designed so that you need not
-include a main program unit written in Fortran in your program---it
-can be written in C or some other language.
-Especially for I/O handling, this is the case, although @command{g77} version 0.5.16
-includes a bug fix for @code{libg2c} that solved a problem with using the
-@code{OPEN} statement as the first Fortran I/O activity in a program
-without a Fortran main program unit.
-
-However, if you don't intend to use @command{g77} (or @command{f2c}) to compile
-your main program unit---that is, if you intend to compile a @code{main()}
-procedure using some other language---you should carefully
-examine the code for @code{main()} in @code{libg2c}, found in the source
-file @file{@value{path-libf2c}/libF77/main.c}, to see what kinds of things
-might need to be done by your @code{main()} in order to provide the
-Fortran environment your Fortran code is expecting.

-@cindex intrinsics, @code{IArgC}

-For example, @code{libg2c}'s @code{main()} sets up the information used by
-the @code{IARGC} and @code{GETARG} intrinsics.
-Bypassing @code{libg2c}'s @code{main()}
-without providing a substitute for this activity would mean
-that invoking @code{IARGC} and @code{GETARG} would produce undefined
-results.

-When debugging, one implication of the fact that @code{main()}, which
-is the place where the debugged program ``starts'' from the
-debugger's point of view, is in @code{libg2c} is that you won't be
-starting your Fortran program at a point you recognize as your
-Fortran code.
-
-The standard way to get around this problem is to set a break
-point (a one-time, or temporary, break point will do) at
-the entrance to @code{MAIN__}, and then run the program.
-A convenient way to do so is to add the @command{gdb} command
-
-@example
-tbreak MAIN__
-@end example
-
-@noindent
-to the file @file{.gdbinit} in the directory in which you're debugging
-(using @command{gdb}).
-
-After doing this, the debugger will see the current execution
-point of the program as at the beginning of the main program
-unit of your program.
-
-Of course, if you really want to set a break point at some
-other place in your program and just start the program
-running, without first breaking at @code{MAIN__},
-that should work fine.

-
-Currently, @command{g77} passes arguments via reference---specifically,
-by passing a pointer to the location in memory of a variable, array,
-array element, a temporary location that holds the result of evaluating an
-expression, or a temporary or permanent location that holds the value
-of a constant.
-
-Procedures that accept @code{CHARACTER} arguments are implemented by
-@command{g77} so that each @code{CHARACTER} argument has two actual arguments.
-
-The first argument occupies the expected position in the
-argument list and has the user-specified name.
-This argument
-is a pointer to an array of characters, passed by the caller.
-
-The second argument is appended to the end of the user-specified
-calling sequence and is named @samp{__g77_length_@var{x}}, where @var{x}
-is the user-specified name.
-This argument is of the C type @code{ftnlen}
-(see @file{@value{path-libf2c}/g2c.h.in} for information on that type) and
-is the number of characters the caller has allocated in the
-array pointed to by the first argument.
-
-A procedure will ignore the length argument if @samp{X} is not declared
-@code{CHARACTER*(*)}, because for other declarations, it knows the
-length.
-Not all callers necessarily ``know'' this, however, which
-is why they all pass the extra argument.
-
-The contents of the @code{CHARACTER} argument are specified by the
-address passed in the first argument (named after it).
-The procedure can read or write these contents as appropriate.
-
-When more than one @code{CHARACTER} argument is present in the argument
-list, the length arguments are appended in the order
-the original arguments appear.
-So @samp{CALL FOO('HI','THERE')} is implemented in
-C as @samp{foo("hi","there",2,5);}, ignoring the fact that @command{g77}
-does not provide the trailing null bytes on the constant
-strings (@command{f2c} does provide them, but they are unnecessary in
-a Fortran environment, and you should not expect them to be
-there).
-
-Note that the above information applies to @code{CHARACTER} variables and
-arrays @strong{only}.
-It does @strong{not} apply to external @code{CHARACTER}
-functions or to intrinsic @code{CHARACTER} functions.
-That is, no second length argument is passed to @samp{FOO} in this case:
-
-@example
-CHARACTER X
-EXTERNAL X
-CALL FOO(X)
-@end example
-
-@noindent
-Nor does @samp{FOO} expect such an argument in this case:
-
-@example
-SUBROUTINE FOO(X)
-CHARACTER X
-EXTERNAL X
-@end example
-
-Because of this implementation detail, if a program has a bug
-such that there is disagreement as to whether an argument is
-a procedure, and the type of the argument is @code{CHARACTER}, subtle
-symptoms might appear.

-@code{CHARACTER}

-@code{COMPLEX}
-@item
-@code{REAL(KIND=1)}
-@end itemize
-
-For @code{CHARACTER}, @command{g77} implements a subroutine (a C function
-returning @code{void})
-with two arguments prepended: @samp{__g77_result}, which the caller passes
-as a pointer to a @code{char} array expected to hold the return value,
-and @samp{__g77_length}, which the caller passes as an @code{ftnlen} value
-specifying the length of the return value as declared in the calling
-program.
-For @code{CHARACTER*(*)}, the called function uses @samp{__g77_length}
-to determine the size of the array that @samp{__g77_result} points to;
-otherwise, it ignores that argument.
-
-For @code{COMPLEX}, when @option{-ff2c} is in
-force, @command{g77} implements
-a subroutine with one argument prepended: @samp{__g77_result}, which the
-caller passes as a pointer to a variable of the type of the function.
-The called function writes the return value into this variable instead
-of returning it as a function value.
-When @option{-fno-f2c} is in force,
-@command{g77} implements a @code{COMPLEX} function as @command{gcc}'s
-@samp{__complex__ float} or @samp{__complex__ double} function
-(or an emulation thereof, when @option{-femulate-complex} is in effect),
-returning the result of the function in the same way as @command{gcc} would.
-
-For @code{REAL(KIND=1)}, when @option{-ff2c} is in force, @command{g77} implements
-a function that actually returns @code{REAL(KIND=2)} (typically

-
-External names---names of entities that are public, or ``accessible'',
-to all modules in a program---normally have an underscore (@samp{_})
-appended by @command{g77},
-to generate code that is compatible with @command{f2c}.
-External names include names of Fortran things like common blocks,
-external procedures (subroutines and functions, but not including
-statement functions, which are internal procedures), and entry point
-names.
-
-However, use of the @option{-fno-underscoring} option
-disables this kind of transformation of external names (though inhibiting
-the transformation certainly improves the chances of colliding with
-incompatible externals written in other languages---but that
-might be intentional.

-When @option{-funderscoring} is in force, any name (external or local)
-that already has at least one underscore in it is
-implemented by @command{g77} by appending two underscores.
-(This second underscore can be disabled via the
-@option{-fno-second-underscore} option.)
-External names are changed this way for @command{f2c} compatibility.
-Local names are changed this way to avoid collisions with external names
-that are different in the source code---@command{f2c} does the same thing, but
-there's no compatibility issue there except for user expectations while
-debugging.
-
-For example:
-
-@example
-Max_Cost = 0
-@end example
-
-@cindex debugging
-@noindent
-Here, a user would, in the debugger, refer to this variable using the
-name @samp{max_cost__} (or @samp{MAX_COST__} or @samp{Max_Cost__},
-as described below).
-(We hope to improve @command{g77} in this regard in the future---don't
-write scripts depending on this behavior!
-Also, consider experimenting with the @option{-fno-underscoring}
-option to try out debugging without having to massage names by
-hand like this.)
-
-@command{g77} provides a number of command-line options that allow the user
-to control how case mapping is handled for source files.
-The default is the traditional UNIX model for Fortran compilers---names
-are mapped to lower case.
-Other command-line options can be specified to map names to upper
-case, or to leave them exactly as written in the source file.
-
-For example:
-
-@example
-Foo = 9.436
-@end example
-
-@noindent
-Here, it is normally the case that the variable assigned will be named
-@samp{foo}.
-This would be the name to enter when using a debugger to
-access the variable.
-
-However, depending on the command-line options specified, the
-name implemented by @command{g77} might instead be @samp{FOO} or even
-@samp{Foo}, thus affecting how debugging is done.
-
-Also:
-
-@example
-Call Foo
-@end example
-
-@noindent
-This would normally call a procedure that, if it were in a separate C program,
-be defined starting with the line:
-
-@example
-void foo_()
-@end example
-
-@noindent
-However, @command{g77} command-line options could be used to change the casing
-of names, resulting in the name @samp{FOO_} or @samp{Foo_} being given to the
-procedure instead of @samp{foo_}, and the @option{-fno-underscoring} option
-could be used to inhibit the appending of the underscore to the name.

-
-Essentially, @command{g77} implements these types using an

-as seen by the @command{gcc} back end.
-
-Currently, the back end, when outputting debugging info with
-the compiled code for the assembler to digest, does not detect

-As a result, the Fortran language modes of debuggers such as

-@cindex array ordering

-@cindex column-major ordering
-@cindex row-major ordering
-@cindex arrays
-
-Fortran uses ``column-major ordering'' in its arrays.
-This differs from other languages, such as C, which use ``row-major ordering''.
-The difference is that, with Fortran, array elements adjacent to
-each other in memory differ in the @emph{first} subscript instead of
-the last; @samp{A(5,10,20)} immediately follows @samp{A(4,10,20)},
-whereas with row-major ordering it would follow @samp{A(5,10,19)}.
-
-This consideration
-affects not only interfacing with and debugging Fortran code,
-it can greatly affect how code is designed and written, especially
-when code speed and size is a concern.
-
-Fortran also differs from C, a popular language for interfacing and
-to support directly in debuggers, in the way arrays are treated.
-In C, arrays are single-dimensional and have interesting relationships
-to pointers, neither of which is true for Fortran.
-As a result, dealing with Fortran arrays from within
-an environment limited to C concepts can be challenging.
-
-For example, accessing the array element @samp{A(5,10,20)} is easy enough
-in Fortran (use @samp{A(5,10,20)}), but in C some difficult machinations
-are needed.
-First, C would treat the A array as a single-dimension array.
-Second, C does not understand low bounds for arrays as does Fortran.
-Third, C assumes a low bound of zero (0), while Fortran defaults to a
-low bound of one (1) and can supports an arbitrary low bound.
-Therefore, calculations must be done
-to determine what the C equivalent of @samp{A(5,10,20)} would be, and these
-calculations require knowing the dimensions of @samp{A}.
-
-For @samp{DIMENSION A(2:11,21,0:29)}, the calculation of the offset of
-@samp{A(5,10,20)} would be:
-
-@example
- (5-2)
-+ (10-1)*(11-2+1)
-+ (20-0)*(11-2+1)*(21-1+1)
-= 4293
-@end example
-
-@noindent
-So the C equivalent in this case would be @samp{a[4293]}.
-
-When using a debugger directly on Fortran code, the C equivalent
-might not work, because some debuggers cannot understand the notion
-of low bounds other than zero. However, unlike @command{f2c}, @command{g77}
-does inform the GBE that a multi-dimensional array (like @samp{A}
-in the above example) is really multi-dimensional, rather than a
-single-dimensional array, so at least the dimensionality of the array
-is preserved.
-
-Debuggers that understand Fortran should have no trouble with
-nonzero low bounds, but for non-Fortran debuggers, especially
-C debuggers, the above example might have a C equivalent of
-@samp{a[4305]}.
-This calculation is arrived at by eliminating the subtraction
-of the lower bound in the first parenthesized expression on each
-line---that is, for @samp{(5-2)} substitute @samp{(5)}, for @samp{(10-1)}
-substitute @samp{(10)}, and for @samp{(20-0)} substitute @samp{(20)}.
-Actually, the implication of
-this can be that the expression @samp{*(&a[2][1][0] + 4293)} works fine,
-but that @samp{a[20][10][5]} produces the equivalent of
-@samp{*(&a[0][0][0] + 4305)} because of the missing lower bounds.
-
-Come to think of it, perhaps
-the behavior is due to the debugger internally compensating for
-the lower bounds by offsetting the base address of @samp{a}, leaving
-@samp{&a} set lower, in this case, than @samp{&a[2][1][0]} (the address of
-its first element as identified by subscripts equal to the
-corresponding lower bounds).
-
-You know, maybe nobody really needs to use arrays.

-
-Adjustable and automatic arrays in Fortran require the implementation
-(in this
-case, the @command{g77} compiler) to ``memorize'' the expressions that
-dimension the arrays each time the procedure is invoked.
-This is so that subsequent changes to variables used in those
-expressions, made during execution of the procedure, do not
-have any effect on the dimensions of those arrays.
-
-For example:
-
-@example
-REAL ARRAY(5)
-DATA ARRAY/5*2/
-CALL X(ARRAY, 5)
-END
-SUBROUTINE X(A, N)
-DIMENSION A(N)
-N = 20
-PRINT *, N, A
-END
-@end example
-
-@noindent
-Here, the implementation should, when running the program, print something
-like:
-
-@example
-20 2. 2. 2. 2. 2.
-@end example
-
-@noindent
-Note that this shows that while the value of @samp{N} was successfully
-changed, the size of the @samp{A} array remained at 5 elements.
-
-To support this, @command{g77} generates code that executes before any user
-code (and before the internally generated computed @code{GOTO} to handle
-alternate entry points, as described below) that evaluates each
-(nonconstant) expression in the list of subscripts for an
-array, and saves the result of each such evaluation to be used when
-determining the size of the array (instead of re-evaluating the
-expressions).
-
-So, in the above example, when @samp{X} is first invoked, code is
-executed that copies the value of @samp{N} to a temporary.
-And that same temporary serves as the actual high bound for the single
-dimension of the @samp{A} array (the low bound being the constant 1).
-Since the user program cannot (legitimately) change the value
-of the temporary during execution of the procedure, the size
-of the array remains constant during each invocation.
-
-For alternate entry points, the code @command{g77} generates takes into
-account the possibility that a dummy adjustable array is not actually
-passed to the actual entry point being invoked at that time.
-In that case, the public procedure implementing the entry point
-passes to the master private procedure implementing all the
-code for the entry points a @code{NULL} pointer where a pointer to that
-adjustable array would be expected.
-The @command{g77}-generated code
-doesn't attempt to evaluate any of the expressions in the subscripts
-for an array if the pointer to that array is @code{NULL} at run time in
-such cases.
-(Don't depend on this particular implementation
-by writing code that purposely passes @code{NULL} pointers where the
-callee expects adjustable arrays, even if you know the callee
-won't reference the arrays---nor should you pass @code{NULL} pointers
-for any dummy arguments used in calculating the bounds of such
-arrays or leave undefined any values used for that purpose in

-@section Alternate Entry Points (ENTRY)
-@cindex alternate entry points
-@cindex entry points
-@cindex ENTRY statement
-@cindex statements, ENTRY
-
-The GBE does not understand the general concept of
-alternate entry points as Fortran provides via the ENTRY statement.
-@command{g77} gets around this by using an approach to compiling procedures
-having at least one @code{ENTRY} statement that is almost identical to the
-approach used by @command{f2c}.
-(An alternate approach could be used that
-would probably generate faster, but larger, code that would also
-be a bit easier to debug.)
-
-Information on how @command{g77} implements @code{ENTRY} is provided for those
-trying to debug such code.
-The choice of implementation seems
-unlikely to affect code (compiled in other languages) that interfaces
-to such code.
-
-@command{g77} compiles exactly one public procedure for the primary entry
-point of a procedure plus each @code{ENTRY} point it specifies, as usual.
-That is, in terms of the public interface, there is no difference
-between
-
-@example
-SUBROUTINE X
-END
-SUBROUTINE Y
-END
-@end example
-
-@noindent
-and:
-
-@example
-SUBROUTINE X
-ENTRY Y
-END
-@end example
-
-The difference between the above two cases lies in the code compiled
-for the @samp{X} and @samp{Y} procedures themselves, plus the fact that,
-for the second case, an extra internal procedure is compiled.
-
-For every Fortran procedure with at least one @code{ENTRY}
-statement, @command{g77} compiles an extra procedure
-named @samp{__g77_masterfun_@var{x}}, where @var{x} is
-the name of the primary entry point (which, in the above case,
-using the standard compiler options, would be @samp{x_} in C).
-
-This extra procedure is compiled as a private procedure---that is,
-a procedure not accessible by name to separately compiled modules.
-It contains all the code in the program unit, including the code
-for the primary entry point plus for every entry point.
-(The code for each public procedure is quite short, and explained later.)
-
-The extra procedure has some other interesting characteristics.
-
-The argument list for this procedure is invented by @command{g77}.
-It contains
-a single integer argument named @samp{__g77_which_entrypoint},
-passed by value (as in Fortran's @samp{%VAL()} intrinsic), specifying the
-entry point index---0 for the primary entry point, 1 for the
-first entry point (the first @code{ENTRY} statement encountered), 2 for
-the second entry point, and so on.
-
-It also contains, for functions returning @code{CHARACTER} and
-(when @option{-ff2c} is in effect) @code{COMPLEX} functions,
-and for functions returning different types among the
-@code{ENTRY} statements (e.g. @samp{REAL FUNCTION R()}
-containing @samp{ENTRY I()}), an argument named @samp{__g77_result} that
-is expected at run time to contain a pointer to where to store
-the result of the entry point.
-For @code{CHARACTER} functions, this
-storage area is an array of the appropriate number of characters;
-for @code{COMPLEX} functions, it is the appropriate area for the return
-type; for multiple-return-type functions, it is a union of all the supported return
-types (which cannot include @code{CHARACTER}, since combining @code{CHARACTER}
-and non-@code{CHARACTER} return types via @code{ENTRY} in a single function
-is not supported by @command{g77}).
-
-For @code{CHARACTER} functions, the @samp{__g77_result} argument is followed
-by yet another argument named @samp{__g77_length} that, at run time,
-specifies the caller's expected length of the returned value.
-Note that only @code{CHARACTER*(*)} functions and entry points actually
-make use of this argument, even though it is always passed by
-all callers of public @code{CHARACTER} functions (since the caller does not
-generally know whether such a function is @code{CHARACTER*(*)} or whether
-there are any other callers that don't have that information).
-
-The rest of the argument list is the union of all the arguments
-specified for all the entry points (in their usual forms, e.g.
-@code{CHARACTER} arguments have extra length arguments, all appended at
-the end of this list).
-This is considered the ``master list'' of
-arguments.
-
-The code for this procedure has, before the code for the first
-executable statement, code much like that for the following Fortran
-statement:
-
-@smallexample
- GOTO (100000,100001,100002), __g77_which_entrypoint
-100000 @dots{}code for primary entry point@dots{}
-100001 @dots{}code immediately following first ENTRY statement@dots{}
-100002 @dots{}code immediately following second ENTRY statement@dots{}
-@end smallexample
-
-@noindent
-(Note that invalid Fortran statement labels and variable names
-are used in the above example to highlight the fact that it
-represents code generated by the @command{g77} internals, not code to be
-written by the user.)
-
-It is this code that, when the procedure is called, picks which
-entry point to start executing.
-
-Getting back to the public procedures (@samp{x} and @samp{Y} in the original
-example), those procedures are fairly simple.
-Their interfaces
-are just like they would be if they were self-contained procedures
-(without @code{ENTRY}), of course, since that is what the callers
-expect.
-Their code consists of simply calling the private
-procedure, described above, with the appropriate extra arguments
-(the entry point index, and perhaps a pointer to a multiple-type-
-return variable, local to the public procedure, that contains
-all the supported returnable non-character types).
-For arguments
-that are not listed for a given entry point that are listed for
-other entry points, and therefore that are in the ``master list''
-for the private procedure, null pointers (in C, the @code{NULL} macro)
-are passed.
-Also, for entry points that are part of a multiple-type-
-returning function, code is compiled after the call of the private
-procedure to extract from the multi-type union the appropriate result,
-depending on the type of the entry point in question, returning
-that result to the original caller.
-
-When debugging a procedure containing alternate entry points, you
-can either set a break point on the public procedure itself (e.g.
-a break point on @samp{X} or @samp{Y}) or on the private procedure that
-contains most of the pertinent code (e.g. @samp{__g77_masterfun_@var{x}}).
-If you do the former, you should use the debugger's command to
-``step into'' the called procedure to get to the actual code; with
-the latter approach, the break point leaves you right at the
-actual code, skipping over the public entry point and its call
-to the private procedure (unless you have set a break point there
-as well, of course).
-
-Further, the list of dummy arguments that is visible when the
-private procedure is active is going to be the expanded version
-of the list for whichever particular entry point is active,
-as explained above, and the way in which return values are
-handled might well be different from how they would be handled
-for an equivalent single-entry function.

-In particular, while @command{g77} implements

-actually generate the name @samp{L10} or any other name like that,
-since debuggers cannot access labels anyway).
-
-While this currently means that an @code{ASSIGN} statement does not

-
-@command{g77} also implements iterative @code{DO} loops
-so that they work even in the presence of certain ``extreme'' inputs,
-unlike @command{f2c}.

-
-@item
-Array bounds expressions (such as @samp{REAL M(N(2))})

-It is expected that @command{g77} will offer some or all of these missing

-
-@node Diagnostic Abilities
-@subsection Diagnostic Abilities
-
-@command{g77} offers better diagnosis of problems in @code{FORMAT} statements.
-@command{f2c} doesn't, for example, emit any diagnostic for
-@samp{FORMAT(XZFAJG10324)},
-leaving that to be diagnosed, at run time, by
-the @code{libf2c} run-time library.
-
-@node Compiler Options
-@subsection Compiler Options
-
-@command{g77} offers compiler options that @command{f2c} doesn't,
-most of which are designed to more easily accommodate
-legacy code:
-
-@itemize @bullet
-@item
-Two that control the automatic appending of extra
-underscores to external names
-
-@item
-One that allows dollar signs (@samp{$}) in symbol names
-
-@item
-A variety that control acceptance of various
-``ugly'' constructs

-One to specify the length of fixed-form source lines
-(normally 72)
-
-@item
-One to specify the the source code is written in
-Fortran-90-style free-form
-@end itemize
-
-However, @command{f2c} offers a few that @command{g77} doesn't,
-like an option to have @code{REAL} default to @code{REAL*8}.
-It is expected that @command{g77} will offer all of the
-missing options pertinent to being a Fortran compiler
-at some time in the future.
-
-@node Compiler Speed
-@subsection Compiler Speed
-
-Saving the steps of writing and then rereading C code is a big reason
-why @command{g77} should be able to compile code much faster than using
-@command{f2c} in conjunction with the equivalent invocation of @command{gcc}.
-
-However, due to @command{g77}'s youth, lots of self-checking is still being
-performed.
-As a result, this improvement is as yet unrealized
-(though the potential seems to be there for quite a big speedup
-in the future).
-It is possible that, as of version 0.5.18, @command{g77}
-is noticeably faster compiling many Fortran source files than using
-@command{f2c} in conjunction with @command{gcc}.
-
-@node Program Speed
-@subsection Program Speed
-
-@command{g77} has the potential to better optimize code than @command{f2c},
-even when @command{gcc} is used to compile the output of @command{f2c},
-because @command{f2c} must necessarily
-translate Fortran into a somewhat lower-level language (C) that cannot
-preserve all the information that is potentially useful for optimization,
-while @command{g77} can gather, preserve, and transmit that information directly
-to the GBE.
-
-For example, @command{g77} implements @code{ASSIGN} and assigned
-@code{GOTO} using direct assignment of pointers to labels and direct
-jumps to labels, whereas @command{f2c} maps the assigned labels to
-integer values and then uses a C @code{switch} statement to encode
-the assigned @code{GOTO} statements.
-
-However, as is typical, theory and reality don't quite match, at least
-not in all cases, so it is still the case that @command{f2c} plus @command{gcc}
-can generate code that is faster than @command{g77}.
-
-Version 0.5.18 of @command{g77} offered default
-settings and options, via patches to the @command{gcc}
-back end, that allow for better program speed, though
-some of these improvements also affected the performance
-of programs translated by @command{f2c} and then compiled
-by @command{g77}'s version of @command{gcc}.
-
-Version 0.5.20 of @command{g77} offers further performance
-improvements, at least one of which (alias analysis) is
-not generally applicable to @command{f2c} (though @command{f2c}
-could presumably be changed to also take advantage of
-this new capability of the @command{gcc} back end, assuming
-this is made available in an upcoming release of @command{gcc}).
-
-@node Ease of Debugging
-@subsection Ease of Debugging
-
-Because @command{g77} compiles directly to assembler code like @command{gcc},
-instead of translating to an intermediate language (C) as does @command{f2c},
-support for debugging can be better for @command{g77} than @command{f2c}.
-
-However, although @command{g77} might be somewhat more ``native'' in terms of
-debugging support than @command{f2c} plus @command{gcc}, there still are a lot
-of things ``not quite right''.
-Many of the important ones should be resolved in the near future.
-
-For example, @command{g77} doesn't have to worry about reserved names
-like @command{f2c} does.
-Given @samp{FOR = WHILE}, @command{f2c} must necessarily
-translate this to something @emph{other} than
-@samp{for = while;}, because C reserves those words.
-
-However, @command{g77} does still uses things like an extra level of indirection
-for @code{ENTRY}-laden procedures---in this case, because the back end doesn't
-yet support multiple entry points.
-
-Another example is that, given
-
-@smallexample
-COMMON A, B
-EQUIVALENCE (B, C)
-@end smallexample
-
-@noindent
-the @command{g77} user should be able to access the variables directly, by name,
-without having to traverse C-like structures and unions, while @command{f2c}
-is unlikely to ever offer this ability (due to limitations in the
-C language).
-
-Yet another example is arrays.
-@command{g77} represents them to the debugger
-using the same ``dimensionality'' as in the source code, while @command{f2c}
-must necessarily convert them all to one-dimensional arrays to fit
-into the confines of the C language.
-However, the level of support
-offered by debuggers for interactive Fortran-style access to arrays
-as compiled by @command{g77} can vary widely.
-In some cases, it can actually
-be an advantage that @command{f2c} converts everything to widely supported
-C semantics.
-
-In fairness, @command{g77} could do many of the things @command{f2c} does
-to get things working at least as well as @command{f2c}---for now,
-the developers prefer making @command{g77} work the
-way they think it is supposed to, and finding help improving the
-other products (the back end of @command{gcc}; @command{gdb}; and so on)
-to get things working properly.

-@command{g77} does not generate such null bytes.

-@samp{BLOCK DATA FOO}) and make sure there is an @samp{EXTERNAL FOO}
-statement in every program unit that uses any common block
-initialized by the corresponding @code{BLOCK DATA}.
-@command{g77} currently compiles a @code{BLOCK DATA} as if it were a
-@code{SUBROUTINE},
-that is, it generates an actual procedure having the appropriate name.
-The procedure does nothing but return immediately if it happens to be
-called.
-For @samp{EXTERNAL FOO}, where @samp{FOO} is not otherwise referenced in the
-same program unit, @command{g77} assumes there exists a @samp{BLOCK DATA FOO}
-in the program and ensures that by generating a
-reference to it so the linker will make sure it is present.
-(Specifically, @command{g77} outputs in the data section a static pointer to the
-external name @samp{FOO}.)
-
-The implementation @command{g77} currently uses to make this work is
-one of the few things not compatible with @command{f2c} as currently

-@command{f2c} currently does nothing with @samp{EXTERNAL FOO} except
-issue a warning that @samp{FOO} is not otherwise referenced,
-and, for @samp{BLOCK DATA FOO},
-@command{f2c} doesn't generate a dummy procedure with the name @samp{FOO}.
-The upshot is that you shouldn't mix @command{f2c} and @command{g77} in
-this particular case.
-If you use @command{f2c} to compile @samp{BLOCK DATA FOO},
-then any @command{g77}-compiled program unit that says @samp{EXTERNAL FOO}
-will result in an unresolved reference when linked.
-If you do the
-opposite, then @samp{FOO} might not be linked in under various
-circumstances (such as when @samp{FOO} is in a library, or you're
-using a ``clever'' linker---so clever, it produces a broken program
-with little or no warning by omitting initializations of global data
-because they are contained in unreferenced procedures).
-
-The changes you make to your code to make @command{g77} handle this situation,
-however, appear to be a widely portable way to handle it.
-That is, many systems permit it (as they should, since the
-FORTRAN 77 standard permits @samp{EXTERNAL FOO} when @samp{FOO}
-is a block data program unit), and of the ones
-that might not link @samp{BLOCK DATA FOO} under some circumstances, most of
-them appear to do so once @samp{EXTERNAL FOO} is present in the appropriate
-program units.
-
-Here is the recommended approach to modifying a program containing
-a program unit such as the following:
-
-@smallexample
-BLOCK DATA FOO
-COMMON /VARS/ X, Y, Z
-DATA X, Y, Z / 3., 4., 5. /
-END
-@end smallexample
-
-@noindent
-If the above program unit might be placed in a library module, then
-ensure that every program unit in every program that references that
-particular @code{COMMON} area uses the @code{EXTERNAL} statement
-to force the area to be initialized.
-
-For example, change a program unit that starts with
-
-@smallexample
-INTEGER FUNCTION CURX()
-COMMON /VARS/ X, Y, Z
-CURX = X
-END
-@end smallexample
-
-@noindent
-so that it uses the @code{EXTERNAL} statement, as in:
-
-@smallexample
-INTEGER FUNCTION CURX()
-COMMON /VARS/ X, Y, Z
-EXTERNAL FOO
-CURX = X
-END
-@end smallexample
-
-@noindent
-That way, @samp{CURX} is compiled by @command{g77} (and many other
-compilers) so that the linker knows it must include @samp{FOO},
-the @code{BLOCK DATA} program unit that sets the initial values
-for the variables in @samp{VAR}, in the executable program.

-@node Loops
-@section Loops
-@cindex DO statement
-@cindex statements, DO
-@cindex trips, number of
-@cindex number of trips
-
-The meaning of a @code{DO} loop in Fortran is precisely specified
-in the Fortran standard@dots{}and is quite different from what
-many programmers might expect.
-
-In particular, Fortran iterative @code{DO} loops are implemented as if
-the number of trips through the loop is calculated @emph{before}
-the loop is entered.
-
-The number of trips for a loop is calculated from the @var{start},
-@var{end}, and @var{increment} values specified in a statement such as:
-
-@smallexample
-DO @var{iter} = @var{start}, @var{end}, @var{increment}
-@end smallexample
-
-@noindent
-The trip count is evaluated using a fairly simple formula
-based on the three values following the @samp{=} in the
-statement, and it is that trip count that is effectively
-decremented during each iteration of the loop.
-If, at the beginning of an iteration of the loop, the
-trip count is zero or negative, the loop terminates.
-The per-loop-iteration modifications to @var{iter} are not
-related to determining whether to terminate the loop.
-
-There are two important things to remember about the trip
-count:
-
-@itemize @bullet
-@item
-It can be @emph{negative}, in which case it is
-treated as if it was zero---meaning the loop is
-not executed at all.
-
-@item
-The type used to @emph{calculate} the trip count
-is the same type as @var{iter}, but the final
-calculation, and thus the type of the trip
-count itself, always is @code{INTEGER(KIND=1)}.
-@end itemize
-
-These two items mean that there are loops that cannot
-be written in straightforward fashion using the Fortran @code{DO}.
-
-For example, on a system with the canonical 32-bit two's-complement
-implementation of @code{INTEGER(KIND=1)}, the following loop will not work:
-
-@smallexample
-DO I = -2000000000, 2000000000
-@end smallexample
-
-@noindent
-Although the @var{start} and @var{end} values are well within
-the range of @code{INTEGER(KIND=1)}, the @emph{trip count} is not.
-The expected trip count is 40000000001, which is outside
-the range of @code{INTEGER(KIND=1)} on many systems.
-
-Instead, the above loop should be constructed this way:
-
-@smallexample
-I = -2000000000
-DO
- IF (I .GT. 2000000000) EXIT
- @dots{}
- I = I + 1
-END DO
-@end smallexample
-
-@noindent
-The simple @code{DO} construct and the @code{EXIT} statement
-(used to leave the innermost loop)
-are F90 features that @command{g77} supports.
-
-Some Fortran compilers have buggy implementations of @code{DO},
-in that they don't follow the standard.
-They implement @code{DO} as a straightforward translation
-to what, in C, would be a @code{for} statement.
-Instead of creating a temporary variable to hold the trip count
-as calculated at run time, these compilers
-use the iteration variable @var{iter} to control
-whether the loop continues at each iteration.
-
-The bug in such an implementation shows up when the
-trip count is within the range of the type of @var{iter},
-but the magnitude of @samp{ABS(@var{end}) + ABS(@var{incr})}
-exceeds that range. For example:
-
-@smallexample
-DO I = 2147483600, 2147483647
-@end smallexample
-
-@noindent
-A loop started by the above statement will work as implemented
-by @command{g77}, but the use, by some compilers, of a
-more C-like implementation akin to
-
-@smallexample
-for (i = 2147483600; i <= 2147483647; ++i)
-@end smallexample
-
-@noindent
-produces a loop that does not terminate, because @samp{i}
-can never be greater than 2147483647, since incrementing it
-beyond that value overflows @samp{i}, setting it to -2147483648.
-This is a large, negative number that still is less than 2147483647.
-
-Another example of unexpected behavior of @code{DO} involves
-using a nonintegral iteration variable @var{iter}, that is,
-a @code{REAL} variable.
-Consider the following program:
-
-@smallexample
- DATA BEGIN, END, STEP /.1, .31, .007/
- DO 10 R = BEGIN, END, STEP
- IF (R .GT. END) PRINT *, R, ' .GT. ', END, '!!'
- PRINT *,R
-10 CONTINUE
- PRINT *,'LAST = ',R
- IF (R .LE. END) PRINT *, R, ' .LE. ', END, '!!'
- END
-@end smallexample
-
-@noindent
-A C-like view of @code{DO} would hold that the two ``exclamatory''
-@code{PRINT} statements are never executed.
-However, this is the output of running the above program
-as compiled by @command{g77} on a GNU/Linux ix86 system:
-
-@smallexample
- .100000001
- .107000001
- .114
- .120999999
- @dots{}
- .289000005
- .296000004
- .303000003
-LAST = .310000002
- .310000002 .LE. .310000002!!
-@end smallexample
-
-Note that one of the two checks in the program turned up
-an apparent violation of the programmer's expectation---yet,
-the loop is correctly implemented by @command{g77}, in that
-it has 30 iterations.
-This trip count of 30 is correct when evaluated using
-the floating-point representations for the @var{begin},
-@var{end}, and @var{incr} values (.1, .31, .007) on GNU/Linux
-ix86 are used.
-On other systems, an apparently more accurate trip count
-of 31 might result, but, nevertheless, @command{g77} is
-faithfully following the Fortran standard, and the result
-is not what the author of the sample program above
-apparently expected.
-(Such other systems might, for different values in the @code{DATA}
-statement, violate the other programmer's expectation,
-for example.)
-
-Due to this combination of imprecise representation
-of floating-point values and the often-misunderstood
-interpretation of @code{DO} by standard-conforming
-compilers such as @command{g77}, use of @code{DO} loops
-with @code{REAL} iteration
-variables is not recommended.
-Such use can be caught by specifying @option{-Wsurprising}.
-@xref{Warning Options}, for more information on this

-@cindex mistyped variables

-@cindex mistyped functions
-@cindex functions, mistyped
-@cindex implicit typing
-
-A fruitful source of bugs in Fortran source code is use, or
-mis-use, of Fortran's implicit-typing feature, whereby the
-type of a variable, array, or function is determined by the
-first character of its name.
-
-Simple cases of this include statements like @samp{LOGX=9.227},
-without a statement such as @samp{REAL LOGX}.
-In this case, @samp{LOGX} is implicitly given @code{INTEGER(KIND=1)}
-type, with the result of the assignment being that it is given
-the value @samp{9}.
-
-More involved cases include a function that is defined starting
-with a statement like @samp{DOUBLE PRECISION FUNCTION IPS(@dots{})}.
-Any caller of this function that does not also declare @samp{IPS}
-as type @code{DOUBLE PRECISION} (or, in GNU Fortran, @code{REAL(KIND=2)})
-is likely to assume it returns
-@code{INTEGER}, or some other type, leading to invalid results
-or even program crashes.
-
-The @option{-Wimplicit} option might catch failures to
-properly specify the types of
-variables, arrays, and functions in the code.
-
-However, in code that makes heavy use of Fortran's
-implicit-typing facility, this option might produce so
-many warnings about cases that are working, it would be
-hard to find the one or two that represent bugs.
-This is why so many experienced Fortran programmers strongly
-recommend widespread use of the @code{IMPLICIT NONE} statement,
-despite it not being standard FORTRAN 77, to completely turn
-off implicit typing.
-(@command{g77} supports @code{IMPLICIT NONE}, as do almost all
-FORTRAN 77 compilers.)
-
-Note that @option{-Wimplicit} catches only implicit typing of
-@emph{names}.
-It does not catch implicit typing of expressions such
-as @samp{X**(2/3)}.
-Such expressions can be buggy as well---in fact, @samp{X**(2/3)}
-is equivalent to @samp{X**0}, due to the way Fortran expressions
-are given types and then evaluated.
-(In this particular case, the programmer probably wanted
-@samp{X**(2./3.)}.)
-
-@node Variables Assumed To Be Zero
-@subsection Variables Assumed To Be Zero
-@cindex zero-initialized variables
-@cindex variables, assumed to be zero
-@cindex uninitialized variables
-
-Many Fortran programs were developed on systems that provided
-automatic initialization of all, or some, variables and arrays
-to zero.
-As a result, many of these programs depend, sometimes
-inadvertently, on this behavior, though to do so violates
-the Fortran standards.
-
-You can ask @command{g77} for this behavior by specifying the
-@option{-finit-local-zero} option when compiling Fortran code.
-(You might want to specify @option{-fno-automatic} as well,
-to avoid code-size inflation for non-optimized compilations.)
-
-Note that a program that works better when compiled with the
-@option{-finit-local-zero} option
-is almost certainly depending on a particular system's,
-or compiler's, tendency to initialize some variables to zero.
-It might be worthwhile finding such cases and fixing them,

-
-@node Variables Assumed To Be Saved
-@subsection Variables Assumed To Be Saved
-@cindex variables, retaining values across calls
-@cindex saved variables
-@cindex static variables
-
-Many Fortran programs were developed on systems that
-saved the values of all, or some, variables and arrays
-across procedure calls.
-As a result, many of these programs depend, sometimes
-inadvertently, on being able to assign a value to a
-variable, perform a @code{RETURN} to a calling procedure,
-and, upon subsequent invocation, reference the previously
-assigned variable to obtain the value.
-
-They expect this despite not using the @code{SAVE} statement
-to specify that the value in a variable is expected to survive
-procedure returns and calls.
-Depending on variables and arrays to retain values across
-procedure calls without using @code{SAVE} to require it violates
-the Fortran standards.
-
-You can ask @command{g77} to assume @code{SAVE} is specified for all
-relevant (local) variables and arrays by using the
-@option{-fno-automatic} option.
-
-Note that a program that works better when compiled with the
-@option{-fno-automatic} option
-is almost certainly depending on not having to use
-the @code{SAVE} statement as required by the Fortran standard.
-It might be worthwhile finding such cases and fixing them,
-using techniques such as compiling with the @samp{-O -Wuninitialized}
-options using @command{g77}.
-
-@node Unwanted Variables
-@subsection Unwanted Variables
-
-The @option{-Wunused} option can find bugs involving
-implicit typing, sometimes
-more easily than using @option{-Wimplicit} in code that makes
-heavy use of implicit typing.
-An unused variable or array might indicate that the
-spelling for its declaration is different from that of
-its intended uses.
-
-Other than cases involving typos, unused variables rarely
-indicate actual bugs in a program.
-However, investigating such cases thoroughly has, on occasion,
-led to the discovery of code that had not been completely
-written---where the programmer wrote declarations as needed
-for the whole algorithm, wrote some or even most of the code
-for that algorithm, then got distracted and forgot that the
-job was not complete.
-
-@node Unused Arguments
-@subsection Unused Arguments
-@cindex unused arguments

-As with unused variables, It is possible that unused arguments
-to a procedure might indicate a bug.

-Note that @option{-W} also enables warnings regarding overflow
-of floating-point constants under certain circumstances.

-@node Surprising Interpretations of Code
-@subsection Surprising Interpretations of Code
-
-The @option{-Wsurprising} option can help find bugs involving

-the way @code{DO} loops with non-integral iteration variables
-are handled.
-Cases found by this option might indicate a difference of
-interpretation between the author of the code involved, and
-a standard-conforming compiler such as @command{g77}.
-Such a difference might produce actual bugs.
-
-In any case, changing the code to explicitly do what the
-programmer might have expected it to do, so @command{g77} and

-The @option{-falias-check}, @option{-fargument-alias},

-and @option{-fno-argument-noalias-global} options,
-introduced in version 0.5.20 and
-@command{g77}'s version 2.7.2.2.f.2 of @command{gcc},
-were withdrawn as of @command{g77} version 0.5.23
-due to their not being supported by @command{gcc} version 2.8.
-
-These options control the assumptions regarding aliasing
-(overlapping) of writes and reads to main memory (core) made
-by the @command{gcc} back end.
-
-The information below still is useful, but applies to
-only those versions of @command{g77} that support the
-alias analysis implied by support for these options.
-
-These options are effective only when compiling with @option{-O}
-(specifying any level other than @option{-O0})
-or with @option{-falias-check}.
-
-The default for Fortran code is @option{-fargument-noalias-global}.
-(The default for C code and code written in other C-based languages
-is @option{-fargument-alias}.
-These defaults apply regardless of whether you use @command{g77} or
-@command{gcc} to compile your code.)
-
-Note that, on some systems, compiling with @option{-fforce-addr} in
-effect can produce more optimal code when the default aliasing
-options are in effect (and when optimization is enabled).
-
-If your program is not working when compiled with optimization,
-it is possible it is violating the Fortran standards (77 and 90)
-by relying on the ability to ``safely'' modify variables and
-arrays that are aliased, via procedure calls, to other variables
-and arrays, without using @code{EQUIVALENCE} to explicitly
-set up this kind of aliasing.
-
-(The FORTRAN 77 standard's prohibition of this sort of
-overlap, generally referred to therein as ``storage
-association'', appears in Sections 15.9.3.6.
-This prohibition allows implementations, such as @command{g77},
-to, for example, implement the passing of procedures and
-even values in @code{COMMON} via copy operations into local,
-perhaps more efficiently accessed temporaries at entry to a
-procedure, and, where appropriate, via copy operations back
-out to their original locations in memory at exit from that
-procedure, without having to take into consideration the
-order in which the local copies are updated by the code,
-among other things.)
-
-To test this hypothesis, try compiling your program with
-the @option{-fargument-alias} option, which causes the
-compiler to revert to assumptions essentially the same as
-made by versions of @command{g77} prior to 0.5.20.
-
-If the program works using this option, that strongly suggests
-that the bug is in your program.
-Finding and fixing the bug(s) should result in a program that
-is more standard-conforming and that can be compiled by @command{g77}
-in a way that results in a faster executable.
-
-(You might want to try compiling with @option{-fargument-noalias},
-a kind of half-way point, to see if the problem is limited to
-aliasing between dummy arguments and @code{COMMON} variables---this
-option assumes that such aliasing is not done, while still allowing
-aliasing among dummy arguments.)
-
-An example of aliasing that is invalid according to the standards
-is shown in the following program, which might @emph{not} produce
-the expected results when executed:
-
-@smallexample
-I = 1
-CALL FOO(I, I)
-PRINT *, I
-END
-
-SUBROUTINE FOO(J, K)
-J = J + K
-K = J * K
-PRINT *, J, K
-END
-@end smallexample
-
-The above program attempts to use the temporary aliasing of the
-@samp{J} and @samp{K} arguments in @samp{FOO} to effect a
-pathological behavior---the simultaneous changing of the values
-of @emph{both} @samp{J} and @samp{K} when either one of them
-is written.
-
-The programmer likely expects the program to print these values:
-
-@example
-2 4
-4
-@end example
-
-However, since the program is not standard-conforming, an
-implementation's behavior when running it is undefined, because
-subroutine @samp{FOO} modifies at least one of the arguments,
-and they are aliased with each other.
-(Even if one of the assignment statements was deleted, the
-program would still violate these rules.
-This kind of on-the-fly aliasing is permitted by the standard
-only when none of the aliased items are defined, or written,
-while the aliasing is in effect.)
-
-As a practical example, an optimizing compiler might schedule
-the @samp{J =} part of the second line of @samp{FOO} @emph{after}
-the reading of @samp{J} and @samp{K} for the @samp{J * K} expression,
-resulting in the following output:
-
-@example
-2 2
-2
-@end example
-
-Essentially, compilers are promised (by the standard and, therefore,
-by programmers who write code they claim to be standard-conforming)
-that if they cannot detect aliasing via static analysis of a single
-program unit's @code{EQUIVALENCE} and @code{COMMON} statements, no
-such aliasing exists.
-In such cases, compilers are free to assume that an assignment to
-one variable will not change the value of another variable, allowing
-it to avoid generating code to re-read the value of the other
-variable, to re-schedule reads and writes, and so on, to produce
-a faster executable.
-
-The same promise holds true for arrays (as seen by the called
-procedure)---an element of one dummy array cannot be aliased
-with, or overlap, any element of another dummy array or be
-in a @code{COMMON} area known to the procedure.
-
-(These restrictions apply only when the procedure defines, or
-writes to, one of the aliased variables or arrays.)
-
-Unfortunately, there is no way to find @emph{all} possible cases of
-violations of the prohibitions against aliasing in Fortran code.
-Static analysis is certainly imperfect, as is run-time analysis,
-since neither can catch all violations.
-(Static analysis can catch all likely violations, and some that
-might never actually happen, while run-time analysis can catch
-only those violations that actually happen during a particular run.
-Neither approach can cope with programs mixing Fortran code with
-routines written in other languages, however.)
-
-Currently, @command{g77} provides neither static nor run-time facilities
-to detect any cases of this problem, although other products might.
-Run-time facilities are more likely to be offered by future
-versions of @command{g77}, though patches improving @command{g77} so that
-it provides either form of detection are welcome.

-
-For several versions prior to 0.5.20, @command{g77} configured its
-version of the @code{libf2c} run-time library so that one of
-its configuration macros, @code{ALWAYS_FLUSH}, was defined.
-
-This was done as a result of a belief that many programs expected
-output to be flushed to the operating system (under UNIX, via
-the @code{fflush()} library call) with the result that errors,
-such as disk full, would be immediately flagged via the
-relevant @code{ERR=} and @code{IOSTAT=} mechanism.
-
-Because of the adverse effects this approach had on the performance
-of many programs, @command{g77} no longer configures @code{libf2c}
-(now named @code{libg2c} in its @command{g77} incarnation)
-to always flush output.
-
-If your program depends on this behavior, either insert the
-appropriate @samp{CALL FLUSH} statements, or modify the sources
-to the @code{libg2c}, rebuild and reinstall @command{g77}, and
-relink your programs with the modified library.
-
-(Ideally, @code{libg2c} would offer the choice at run-time, so
-that a compile-time option to @command{g77} or @command{f2c} could
-result in generating the appropriate calls to flushing or
-non-flushing library routines.)
-
-Some Fortran programs require output
-(writes) to be flushed to the operating system (under UNIX,
-via the @code{fflush()} library call) so that errors,
-such as disk full, are immediately flagged via the relevant
-@code{ERR=} and @code{IOSTAT=} mechanism, instead of such
-errors being flagged later as subsequent writes occur, forcing
-the previously written data to disk, or when the file is
-closed.
-
-Essentially, the difference can be viewed as synchronous error
-reporting (immediate flagging of errors during writes) versus
-asynchronous, or, more precisely, buffered error reporting
-(detection of errors might be delayed).
-
-@code{libg2c} supports flagging write errors immediately when
-it is built with the @code{ALWAYS_FLUSH} macro defined.
-This results in a @code{libg2c} that runs slower, sometimes
-quite a bit slower, under certain circumstances---for example,
-accessing files via the networked file system NFS---but the
-effect can be more reliable, robust file I/O.
-
-If you know that Fortran programs requiring this level of precision
-of error reporting are to be compiled using the
-version of @command{g77} you are building, you might wish to
-modify the @command{g77} source tree so that the version of
-@code{libg2c} is built with the @code{ALWAYS_FLUSH} macro
-defined, enabling this behavior.
-
-To do this, find this line in @file{@value{path-libf2c}/f2c.h} in
-your @command{g77} source tree:
-
-@example
-/* #define ALWAYS_FLUSH */
-@end example
-
-Remove the leading @samp{/*@w{ }},
-so the line begins with @samp{#define},
-and the trailing @samp{@w{ }*/}.
-
-Then build or rebuild @command{g77} as appropriate.

-
-If your program crashes at run time with a message including
-the text @samp{illegal unit number}, that probably is
-a message from the run-time library, @code{libg2c}.
-
-The message means that your program has attempted to use a

-@code{libg2c}.
-Normally, this range is 0 through 99, and the high end
-of the range is controlled by a @code{libg2c} source-file
-macro named @code{MXUNIT}.
-
-If you can easily change your program to use unit numbers
-in the range 0 through 99, you should do so.
-
-As distributed, whether as part of @command{f2c} or @command{g77},
-@code{libf2c} accepts file unit numbers only in the range
-0 through 99.
-For example, a statement such as @samp{WRITE (UNIT=100)} causes
-a run-time crash in @code{libf2c}, because the unit number,
-100, is out of range.
-
-If you know that Fortran programs at your installation require
-the use of unit numbers higher than 99, you can change the
-value of the @code{MXUNIT} macro, which represents the maximum unit
-number, to an appropriately higher value.

-Some are more problematic
-than others, depending on how portable and maintainable you want the

-at all is crucial).
-
-You should not continue to use these command-line options to compile

-
-@table @code
-@cindex -finit-local-zero option
-@cindex options, -finit-local-zero
-@item -finit-local-zero
-(This option specifies that any uninitialized local variables

-
-It is safer (and probably
-would produce a faster program) to find the variables and arrays that
-need such initialization and provide it explicitly via @code{DATA}, so that
-@option{-finit-local-zero} is not needed.
-
-Consider using @option{-Wuninitialized} (which requires @option{-O}) to

-are to be treated as if they were named in @code{SAVE} statements.)
-
-Many other compilers do this automatically, which means lots of
-Fortran code developed with those compilers depends on it.
-
-The effect of this is that all non-automatic variables and arrays
-are made static, that is, not placed on the stack or in heap storage.
-This might cause a buggy program to appear to work better.
-If so, rather than relying on this command-line option (and hoping all

-@cindex Pentium optimizations
-@cindex optimization, for Pentium
-
-On some systems, such as those with Pentium Pro CPUs, programs
-that make heavy use of @code{REAL(KIND=2)} (@code{DOUBLE PRECISION})
-might run much slower
-than possible due to the compiler not aligning these 64-bit
-values to 64-bit boundaries in memory.
-(The effect also is present, though
-to a lesser extent, on the 586 (Pentium) architecture.)
-
-The Intel x86 architecture generally ensures that these programs will
-work on all its implementations,
-but particular implementations (such as Pentium Pro)
-perform better with more strict alignment.
-(Such behavior isn't unique to the Intel x86 architecture.)
-Other architectures might @emph{demand} 64-bit alignment
-of 64-bit data.
-
-There are a variety of approaches to use to address this problem:
-
-@itemize @bullet
-@item
-@cindex @code{COMMON} layout
-@cindex layout of @code{COMMON} blocks
-Order your @code{COMMON} and @code{EQUIVALENCE} areas such
-that the variables and arrays with the widest alignment
-guidelines come first.
-
-For example, on most systems, this would mean placing
-@code{COMPLEX(KIND=2)}, @code{REAL(KIND=2)}, and
-@code{INTEGER(KIND=2)} entities first, followed by @code{REAL(KIND=1)},
-@code{INTEGER(KIND=1)}, and @code{LOGICAL(KIND=1)} entities, then
-@code{INTEGER(KIND=6)} entities, and finally @code{CHARACTER}
-and @code{INTEGER(KIND=3)} entities.
-
-The reason to use such placement is it makes it more likely
-that your data will be aligned properly, without requiring
-you to do detailed analysis of each aggregate (@code{COMMON}
-and @code{EQUIVALENCE}) area.
-
-Specifically, on systems where the above guidelines are
-appropriate, placing @code{CHARACTER} entities before
-@code{REAL(KIND=2)} entities can work just as well,
-but only if the number of bytes occupied by the @code{CHARACTER}
-entities is divisible by the recommended alignment for
-@code{REAL(KIND=2)}.
-
-By ordering the placement of entities in aggregate
-areas according to the simple guidelines above, you
-avoid having to carefully count the number of bytes
-occupied by each entity to determine whether the
-actual alignment of each subsequent entity meets the
-alignment guidelines for the type of that entity.
-
-If you don't ensure correct alignment of @code{COMMON} elements, the
-compiler may be forced by some systems to violate the Fortran semantics by
-adding padding to get @code{DOUBLE PRECISION} data properly aligned.
-If the unfortunate practice is employed of overlaying different types of
-data in the @code{COMMON} block, the different variants
-of this block may become misaligned with respect to each other.
-Even if your platform doesn't require strict alignment,
-@code{COMMON} should be laid out as above for portability.
-(Unfortunately the FORTRAN 77 standard didn't anticipate this
-possible requirement, which is compiler-independent on a given platform.)
-
-@item
-@cindex -malign-double option
-@cindex options, -malign-double
-Use the (x86-specific) @option{-malign-double} option when compiling
-programs for the Pentium and Pentium Pro architectures (called 586
-and 686 in the @command{gcc} configuration subsystem).
-The warning about this in the @command{gcc} manual isn't
-generally relevant to Fortran,
-but using it will force @code{COMMON} to be padded if necessary to align
-@code{DOUBLE PRECISION} data.
-
-When @code{DOUBLE PRECISION} data is forcibly aligned
-in @code{COMMON} by @command{g77} due to specifying @option{-malign-double},
-@command{g77} issues a warning about the need to
-insert padding.
-
-In this case, each and every program unit that uses
-the same @code{COMMON} area
-must specify the same layout of variables and their types
-for that area
-and be compiled with @option{-malign-double} as well.
-@command{g77} will issue warnings in each case,
-but as long as every program unit using that area
-is compiled with the same warnings,
-the resulting object files should work when linked together
-unless the program makes additional assumptions about
-@code{COMMON} area layouts that are outside the scope
-of the FORTRAN 77 standard,
-or uses @code{EQUIVALENCE} or different layouts
-in ways that assume no padding is ever inserted by the compiler.
-
-@item

-
-If you're using @option{-fno-automatic} already, you probably
-should change your code to allow compilation with @option{-fautomatic}
-(the default), to allow the program to run faster.
-
-Similarly, you should be able to use @option{-fno-init-local-zero}
-(the default) instead of @option{-finit-local-zero}.
-This is because it is rare that every variable affected by these
-options in a given program actually needs to
-be so affected.
-
-For example, @option{-fno-automatic}, which effectively @code{SAVE}s
-every local non-automatic variable and array, affects even things like
-@code{DO} iteration
-variables, which rarely need to be @code{SAVE}d, and this often reduces
-run-time performances.
-Similarly, @option{-fno-init-local-zero} forces such
-variables to be initialized to zero---when @code{SAVE}d (such as when
-@option{-fno-automatic}), this by itself generally affects only
-startup time for a program, but when not @code{SAVE}d,

-Generally these problems are referred to in this document

-stresses the hardware more than other popular operating
-systems.
-When hardware problems do occur under GNU/Linux on x86

-problems, as illustrated by the following diagnostic:

-It is @emph{very} important to remember that the above
-message is @emph{not} the only one that indicates a

-Developers of Fortran code on NeXTStep (all architectures) have to
-watch out for the following problem when writing programs with
-large, statically allocated (i.e. non-stack based) data structures
-(common blocks, saved arrays).
-
-Due to the way the native loader (@file{/bin/ld}) lays out
-data structures in virtual memory, it is very easy to create an
-executable wherein the @samp{__DATA} segment overlaps (has addresses in
-common) with the @samp{UNIX STACK} segment.
-
-This leads to all sorts of trouble, from the executable simply not
-executing, to bus errors.
-The NeXTStep command line tool @command{ebadexec} points to
-the problem as follows:
-
-@smallexample
-% @kbd{/bin/ebadexec a.out}
-/bin/ebadexec: __LINKEDIT segment (truncated address = 0x3de000
-rounded size = 0x2a000) of executable file: a.out overlaps with UNIX
-STACK segment (truncated address = 0x400000 rounded size =
-0x3c00000) of executable file: a.out
-@end smallexample
-
-(In the above case, it is the @samp{__LINKEDIT} segment that overlaps the
-stack segment.)
-
-This can be cured by assigning the @samp{__DATA} segment
-(virtual) addresses beyond the stack segment.
-A conservative
-estimate for this is from address 6000000 (hexadecimal) onwards---this
-has always worked for me [Toon Moene]:
-
-@smallexample
-% @kbd{g77 -segaddr __DATA 6000000 test.f}
-% @kbd{ebadexec a.out}
-ebadexec: file: a.out appears to be executable
-%
-@end smallexample
-
-Browsing through @file{@value{path-g77}/Makefile.in},
-you will find that the @code{f771} program itself also has to be
-linked with these flags---it has large statically allocated
-data structures.
-(Version 0.5.18 reduces this somewhat, but probably

-@node Stack Overflow
-@subsection Stack Overflow
-@cindex stack, overflow
-@cindex segmentation violation
-@command{g77} code might fail at runtime (probably with a ``segmentation
-violation'') due to overflowing the stack.
-This happens most often on systems with an environment
-that provides substantially more heap space (for use
-when arbitrarily allocating and freeing memory) than stack
-space.
-
-Often this can be cured by
-increasing or removing your shell's limit on stack usage, typically
-using @kbd{limit stacksize} (in @command{csh} and derivatives) or
-@kbd{ulimit -s} (in @command{sh} and derivatives).
-
-Increasing the allowed stack size might, however, require
-changing some operating system or system configuration parameters.
-
-You might be able to work around the problem by compiling with the
-@option{-fno-automatic} option to reduce stack usage, probably at the
-expense of speed.
-
-@command{g77}, on most machines, puts many variables and arrays on the stack
-where possible, and can be configured (by changing
-@code{FFECOM_sizeMAXSTACKITEM} in @file{@value{path-g77}/com.c}) to force
-smaller-sized entities into static storage (saving
-on stack space) or permit larger-sized entities to be put on the
-stack (which can improve run-time performance, as it presents
-more opportunities for the GBE to optimize the generated code).
-
-@emph{Note:} Putting more variables and arrays on the stack
-might cause problems due to system-dependent limits on stack size.
-Also, the value of @code{FFECOM_sizeMAXSTACKITEM} has no
-effect on automatic variables and arrays.
-@xref{But-bugs}, for more information.
-@emph{Note:} While @code{libg2c} places a limit on the range
-of Fortran file-unit numbers, the underlying library and operating

-For example, some systems limit the number of files simultaneously
-open by a running program.
-Information on how to increase these limits should be found

-@cindex automatic arrays
-@cindex arrays, automatic
-However, if your program uses large automatic arrays
-(for example, has declarations like @samp{REAL A(N)} where
-@samp{A} is a local array and @samp{N} is a dummy or
-@code{COMMON} variable that can have a large value),
-neither use of @option{-fno-automatic},
-nor changing the cut-off point for @command{g77} for using the stack,
-will solve the problem by changing the placement of these
-large arrays, as they are @emph{necessarily} automatic.
-
-@command{g77} currently provides no means to specify that
-automatic arrays are to be allocated on the heap instead
-of the stack.
-So, other than increasing the stack size, your best bet is to
-change your source code to avoid large automatic arrays.
-Methods for doing this currently are outside the scope of
-this document.
-
-(@emph{Note:} If your system puts stack and heap space in the
-same memory area, such that they are effectively combined, then
-a stack overflow probably indicates a program that is either
-simply too large for the system, or buggy.)

-@node Nothing Happens
-@subsection Nothing Happens
-@cindex nothing happens
-@cindex naming programs
-@cindex @command{test} programs
-@cindex programs, @command{test}
-It is occasionally reported that a ``simple'' program,
-such as a ``Hello, World!'' program, does nothing when
-it is run, even though the compiler reported no errors,
-despite the program containing nothing other than a
-simple @code{PRINT} statement.
-
-This most often happens because the program has been
-compiled and linked on a UNIX system and named @command{test},
-though other names can lead to similarly unexpected
-run-time behavior on various systems.
-
-Essentially this problem boils down to giving
-your program a name that is already known to
-the shell you are using to identify some other program,
-which the shell continues to execute instead of your
-program when you invoke it via, for example:
-
-@smallexample
-sh# @kbd{test}
-sh#
-@end smallexample
-
-Under UNIX and many other system, a simple command name
-invokes a searching mechanism that might well not choose
-the program located in the current working directory if
-there is another alternative (such as the @command{test}
-command commonly installed on UNIX systems).
-
-The reliable way to invoke a program you just linked in
-the current directory under UNIX is to specify it using
-an explicit pathname, as in:
-
-@smallexample
-sh# @kbd{./test}
- Hello, World!
-sh#
-@end smallexample
-
-Users who encounter this problem should take the time to
-read up on how their shell searches for commands, how to
-set their search path, and so on.
-The relevant UNIX commands to learn about include
-@command{man}, @command{info} (on GNU systems), @command{setenv} (or
-@command{set} and @command{env}), @command{which}, and @command{find}.

-@node Strange Behavior at Run Time
-@subsection Strange Behavior at Run Time
-@cindex segmentation violation
-@cindex bus error
-@cindex overwritten data
-@cindex data, overwritten
-@command{g77} code might fail at runtime with ``segmentation violation'',
-``bus error'', or even something as subtle as a procedure call
-overwriting a variable or array element that it is not supposed
-to touch.
-
-These can be symptoms of a wide variety of actual bugs that
-occurred earlier during the program's run, but manifested
-themselves as @emph{visible} problems some time later.
-
-Overflowing the bounds of an array---usually by writing beyond
-the end of it---is one of two kinds of bug that often occurs
-in Fortran code.
-(Compile your code with the @option{-fbounds-check} option
-to catch many of these kinds of errors at program run time.)
-
-The other kind of bug is a mismatch between the actual arguments
-passed to a procedure and the dummy arguments as declared by that
-procedure.
-
-Both of these kinds of bugs, and some others as well, can be
-difficult to track down, because the bug can change its behavior,
-or even appear to not occur, when using a debugger.
-
-That is, these bugs can be quite sensitive to data, including
-data representing the placement of other data in memory (that is,
-pointers, such as the placement of stack frames in memory).
-
-@command{g77} now offers the
-ability to catch and report some of these problems at compile, link, or
-run time, such as by generating code to detect references to
-beyond the bounds of most arrays (except assumed-size arrays),
-and checking for agreement between calling and called procedures.
-Future improvements are likely to be made in the procedure-mismatch area,
-at least.
-
-In the meantime, finding and fixing the programming
-bugs that lead to these behaviors is, ultimately, the user's
-responsibility, as difficult as that task can sometimes be.
-
-@cindex infinite spaces printed
-@cindex space, endless printing of
-@cindex libc, non-ANSI or non-default
-@cindex C library
-@cindex linking against non-standard library
-@cindex Solaris
-One runtime problem that has been observed might have a simple solution.
-If a formatted @code{WRITE} produces an endless stream of spaces, check
-that your program is linked against the correct version of the C library.
-The configuration process takes care to account for your
-system's normal @file{libc} not being ANSI-standard, which will
-otherwise cause this behavior.
-If your system's default library is
-ANSI-standard and you subsequently link against a non-ANSI one, there
-might be problems such as this one.
-
-Specifically, on Solaris2 systems,

-@node Floating-point Errors
-@subsection Floating-point Errors
-@cindex floating-point errors
-@cindex rounding errors
-@cindex inconsistent floating-point results
-@cindex results, inconsistent
-Some programs appear to produce inconsistent floating-point
-results compiled by @command{g77} versus by other compilers.
-
-Often the reason for this behavior is the fact that floating-point
-values are represented on almost all Fortran systems by
-@emph{approximations}, and these approximations are inexact
-even for apparently simple values like 0.1, 0.2, 0.3, 0.4, 0.6,
-0.7, 0.8, 0.9, 1.1, and so on.
-Most Fortran systems, including all current ports of @command{g77},
-use binary arithmetic to represent these approximations.
-
-Therefore, the exact value of any floating-point approximation
-as manipulated by @command{g77}-compiled code is representable by
-adding some combination of the values 1.0, 0.5, 0.25, 0.125, and
-so on (just keep dividing by two) through the precision of the
-fraction (typically around 23 bits for @code{REAL(KIND=1)}, 52 for
-@code{REAL(KIND=2)}), then multiplying the sum by a integral
-power of two (in Fortran, by @samp{2**N}) that typically is between
--127 and +128 for @code{REAL(KIND=1)} and -1023 and +1024 for
-@code{REAL(KIND=2)}, then multiplying by -1 if the number
-is negative.
-
-So, a value like 0.2 is exactly represented in decimal---since
-it is a fraction, @samp{2/10}, with a denominator that is compatible
-with the base of the number system (base 10).
-However, @samp{2/10} cannot be represented by any finite number
-of sums of any of 1.0, 0.5, 0.25, and so on, so 0.2 cannot
-be exactly represented in binary notation.
-
-(On the other hand, decimal notation can represent any binary
-number in a finite number of digits.
-Decimal notation cannot do so with ternary, or base-3,
-notation, which would represent floating-point numbers as
-sums of any of @samp{1/1}, @samp{1/3}, @samp{1/9}, and so on.
-After all, no finite number of decimal digits can exactly
-represent @samp{1/3}.
-Fortunately, few systems use ternary notation.)
-
-Moreover, differences in the way run-time I/O libraries convert
-between these approximations and the decimal representation often
-used by programmers and the programs they write can result in
-apparent differences between results that do not actually exist,
-or exist to such a small degree that they usually are not worth
-worrying about.
-
-For example, consider the following program:
-
-@smallexample
-PRINT *, 0.2
-END
-@end smallexample
-
-When compiled by @command{g77}, the above program might output
-@samp{0.20000003}, while another compiler might produce a
-executable that outputs @samp{0.2}.
-
-This particular difference is due to the fact that, currently,
-conversion of floating-point values by the @code{libg2c} library,
-used by @command{g77}, handles only double-precision values.
-
-Since @samp{0.2} in the program is a single-precision value, it
-is converted to double precision (still in binary notation)
-before being converted back to decimal.
-The conversion to binary appends @emph{binary} zero digits to the
-original value---which, again, is an inexact approximation of
-0.2---resulting in an approximation that is much less exact
-than is connoted by the use of double precision.
-
-(The appending of binary zero digits has essentially the same
-effect as taking a particular decimal approximation of
-@samp{1/3}, such as @samp{0.3333333}, and appending decimal
-zeros to it, producing @samp{0.33333330000000000}.
-Treating the resulting decimal approximation as if it really
-had 18 or so digits of valid precision would make it seem
-a very poor approximation of @samp{1/3}.)
-
-As a result of converting the single-precision approximation
-to double precision by appending binary zeros, the conversion
-of the resulting double-precision
-value to decimal produces what looks like an incorrect
-result, when in fact the result is @emph{inexact}, and
-is probably no less inaccurate or imprecise an approximation
-of 0.2 than is produced by other compilers that happen to output
-the converted value as ``exactly'' @samp{0.2}.
-(Some compilers behave in a way that can make them appear
-to retain more accuracy across a conversion of a single-precision
-constant to double precision.
-@xref{Context-Sensitive Constants}, to see why
-this practice is illusory and even dangerous.)
-
-Note that a more exact approximation of the constant is
-computed when the program is changed to specify a
-double-precision constant:
-
-@smallexample
-PRINT *, 0.2D0
-END
-@end smallexample
-
-Future versions of @command{g77} and/or @code{libg2c} might convert
-single-precision values directly to decimal,
-instead of converting them to double precision first.
-This would tend to result in output that is more consistent
-with that produced by some other Fortran implementations.

-@node Better Source Model
-@subsection Better Source Model
-
-@command{g77} needs to provide, as the default source-line model,
-a ``pure visual'' mode, where
-the interpretation of a source program in this mode can be accurately
-determined by a user looking at a traditionally displayed rendition
-of the program (assuming the user knows whether the program is fixed
-or free form).
-
-The design should assume the user cannot tell tabs from spaces
-and cannot see trailing spaces on lines, but has canonical tab stops
-and, for fixed-form source, has the ability to always know exactly
-where column 72 is (since the Fortran standard itself requires
-this for fixed-form source).
-
-This would change the default treatment of fixed-form source
-to not treat lines with tabs as if they were infinitely long---instead,
-they would end at column 72 just as if the tabs were replaced
-by spaces in the canonical way.
-
-As part of this, provide common alternate models (Digital, @command{f2c},
-and so on) via command-line options.
-This includes allowing arbitrarily long
-lines for free-form source as well as fixed-form source and providing
-various limits and diagnostics as appropriate.
-
-@cindex sequence numbers
-@cindex columns 73 through 80
-Also, @command{g77} should offer, perhaps even default to, warnings
-when characters beyond the last valid column are anything other
-than spaces.
-This would mean code with ``sequence numbers'' in columns 73 through 80
-would be rejected, and there's a lot of that kind of code around,
-but one of the most frequent bugs encountered by new users is
-accidentally writing fixed-form source code into and beyond
-column 73.
-So, maybe the users of old code would be able to more easily handle
-having to specify, say, a @option{-Wno-col73to80} option.

-
-@command{g77} does not support many of the features that
-distinguish Fortran 90 (and, now, Fortran 95) from
-ANSI FORTRAN 77.
-
-Some Fortran 90 features are supported, because they
-make sense to offer even to die-hard users of F77.
-For example, many of them codify various ways F77 has
-been extended to meet users' needs during its tenure,
-so @command{g77} might as well offer them as the primary
-way to meet those same needs, even if it offers compatibility
-with one or more of the ways those needs were met
-by other F77 compilers in the industry.
-
-Still, many important F90 features are not supported,
-because no attempt has been made to research each and
-every feature and assess its viability in @command{g77}.
-In the meantime, users who need those features must
-use Fortran 90 compilers anyway, and the best approach
-to adding some F90 features to GNU Fortran might well be
-to fund a comprehensive project to create GNU Fortran 95.

-Related to this, @command{g77} doesn't allow non-integral
-exponentiation in @code{PARAMETER} statements, such as
-@samp{PARAMETER (R=2**.25)}.
-It is unlikely @command{g77} will ever support this feature,
-as doing it properly requires complete emulation of
-a target computer's floating-point facilities when
-building @command{g77} as a cross-compiler.
-But, if the @command{gcc} back end is enhanced to provide

-They also typically offer another option (@option{-i8}) to increase

-
-(There are potential pitfalls in using these options.)
-
-@command{g77} does not yet offer any option that performs these

-Part of the problem is the lack of detailed specifications regarding

-
-Until @command{g77} addresses this need, programmers could improve

-@node Sensible Non-standard Constructs
-@subsection Sensible Non-standard Constructs
-
-@command{g77} rejects things other compilers accept,
-like @samp{INTRINSIC SQRT,SQRT}.
-As time permits in the future, some of these things that are easy for
-humans to read and write and unlikely to be intended to mean something
-else will be accepted by @command{g77} (though @option{-fpedantic} should
-trigger warnings about such non-standard constructs).
-
-Until @command{g77} no longer gratuitously rejects sensible code,
-you might as well fix your code
-to be more standard-conforming and portable.
-
-The kind of case that is important to except from the
-recommendation to change your code is one where following
-good coding rules would force you to write non-standard
-code that nevertheless has a clear meaning.
-
-For example, when writing an @code{INCLUDE} file that
-defines a common block, it might be appropriate to
-include a @code{SAVE} statement for the common block
-(such as @samp{SAVE /CBLOCK/}), so that variables
-defined in the common block retain their values even
-when all procedures declaring the common block become
-inactive (return to their callers).
-
-However, putting @code{SAVE} statements in an @code{INCLUDE}
-file would prevent otherwise standard-conforming code
-from also specifying the @code{SAVE} statement, by itself,
-to indicate that all local variables and arrays are to
-have the @code{SAVE} attribute.
-
-For this reason, @command{g77} already has been changed to
-allow this combination, because although the general
-problem of gratuitously rejecting unambiguous and
-``safe'' constructs still exists in @command{g77}, this
-particular construct was deemed useful enough that
-it was worth fixing @command{g77} for just this case.
-
-So, while there is no need to change your code
-to avoid using this particular construct, there
-might be other, equally appropriate but non-standard
-constructs, that you shouldn't have to stop using
-just because @command{g77} (or any other compiler)
-gratuitously rejects it.
-
-Until the general problem is solved, if you have
-any such construct you believe is worthwhile
-using (e.g. not just an arbitrary, redundant
-specification of an attribute), please submit a
-bug report with an explanation, so we can consider
-fixing @command{g77} just for cases like yours.

-@subsection @code{READONLY} Keyword

-Most systems provide some C-callable mechanism to change this; this can

-Fixing this requires one of the following:

-@itemize @bullet

-Switch to new library, @code{libg77}, that provides
-a more ``clean'' interface,
-vis-a-vis input, output, and modified arguments,
-so the GBE can tell what's going on.

-
-@item
-Have @command{g77} pass a pointer to a temporary

-@node Portable Unformatted Files
-@subsection Portable Unformatted Files
-
-@cindex unformatted files
-@cindex file formats
-@cindex binary data
-@cindex byte ordering
-@command{g77} has no facility for exchanging unformatted files with systems
-using different number formats---even differing only in endianness (byte
-order)---or written by other compilers. Some compilers provide
-facilities at least for doing byte-swapping during unformatted I/O.
-
-It is unrealistic to expect to cope with exchanging unformatted files
-with arbitrary other compiler runtimes, but the @command{g77} runtime
-should at least be able to read files written by @command{g77} on systems
-with different number formats, particularly if they differ only in byte
-order.
-
-In case you do need to write a program to translate to or from
-@command{g77} (@code{libf2c}) unformatted files, they are written as
-follows:
-@table @asis
-@item Sequential
-Unformatted sequential records consist of
-@enumerate
-@item
-A number giving the length of the record contents;
-@item
-the length of record contents again (for backspace).
-@end enumerate
-
-The record length is of C type
-@code{long}; this means that it is 8 bytes on 64-bit systems such as
-Alpha GNU/Linux and 4 bytes on other systems, such as x86 GNU/Linux.
-Consequently such files cannot be exchanged between 64-bit and 32-bit
-systems, even with the same basic number format.
-@item Direct access
-Unformatted direct access files form a byte stream of length
-@var{records}*@var{recl} bytes, where @var{records} is the maximum
-record number (@code{REC=@var{records}}) written and @var{recl} is the
-record length in bytes specified in the @code{OPEN} statement
-(@code{RECL=@var{recl}}). Data appear in the records as determined by
-the relevant @code{WRITE} statement. Dummy records with arbitrary
-contents appear in the file in place of records which haven't been
-written.
-@end table
-
-Thus for exchanging a sequential or direct access unformatted file
-between big- and little-endian 32-bit systems using IEEE 754 floating
-point it would be sufficient to reverse the bytes in consecutive words
-in the file if, and @emph{only} if, only @code{REAL*4}, @code{COMPLEX},
-@code{INTEGER*4} and/or @code{LOGICAL*4} data have been written to it by
-@command{g77}.
-
-If necessary, it is possible to do byte-oriented i/o with @command{g77}'s
-@code{FGETC} and @code{FPUTC} intrinsics. Byte-swapping can be done in
-Fortran by equivalencing larger sized variables to an @code{INTEGER*1}
-array or a set of scalars.
-
-@cindex HDF
-@cindex PDB
-If you need to exchange binary data between arbitrary system and
-compiler variations, we recommend using a portable binary format with
-Fortran bindings, such as NCSA's HDF (@uref{http://hdf.ncsa.uiuc.edu/})
-or PACT's PDB@footnote{No, not @emph{that} one.}
-(@uref{http://www.llnl.gov/def_sci/pact/pact_homepage.html}). (Unlike,

-@cindex backslash
-@cindex @command{f77} support
-@cindex support, @command{f77}
-
-In the opinion of many experienced Fortran users,
-@option{-fno-backslash} should be the default, not @option{-fbackslash},
-as currently set by @command{g77}.
-
-First of all, you can always specify
-@option{-fno-backslash} to turn off this processing.
-
-Despite not being within the spirit (though apparently within the
-letter) of the ANSI FORTRAN 77 standard, @command{g77} defaults to
-@option{-fbackslash} because that is what most UNIX @command{f77} commands
-default to, and apparently lots of code depends on this feature.
-
-This is a particularly troubling issue.
-The use of a C construct in the midst of Fortran code
-is bad enough, worse when it makes existing Fortran
-programs stop working (as happens when programs written
-for non-UNIX systems are ported to UNIX systems with
-compilers that provide the @option{-fbackslash} feature
-as the default---sometimes with no option to turn it off).
-
-The author of GNU Fortran wished, for reasons of linguistic
-purity, to make @option{-fno-backslash} the default for GNU
-Fortran and thus require users of UNIX @command{f77} and @command{f2c}
-to specify @option{-fbackslash} to get the UNIX behavior.
-
-However, the realization that @command{g77} is intended as
-a replacement for @emph{UNIX} @command{f77}, caused the author
-to choose to make @command{g77} as compatible with
-@command{f77} as feasible, which meant making @option{-fbackslash}
-the default.
-
-The primary focus on compatibility is at the source-code
-level, and the question became ``What will users expect
-a replacement for @command{f77} to do, by default?''
-Although at least one UNIX @command{f77} does not provide
-@option{-fbackslash} as a default, it appears that
-the majority of them do, which suggests that
-the majority of code that is compiled by UNIX @command{f77}
-compilers expects @option{-fbackslash} to be the default.
-
-It is probably the case that more code exists
-that would @emph{not} work with @option{-fbackslash}
-in force than code that requires it be in force.
-
-However, most of @emph{that} code is not being compiled
-with @command{f77},
-and when it is, new build procedures (shell scripts,
-makefiles, and so on) must be set up anyway so that
-they work under UNIX.
-That makes a much more natural and safe opportunity for
-non-UNIX users to adapt their build procedures for
-@command{g77}'s default of @option{-fbackslash} than would
-exist for the majority of UNIX @command{f77} users who
-would have to modify existing, working build procedures
-to explicitly specify @option{-fbackslash} if that was
-not the default.
-
-One suggestion has been to configure the default for
-@option{-fbackslash} (and perhaps other options as well)
-based on the configuration of @command{g77}.
-
-This is technically quite straightforward, but will be avoided
-even in cases where not configuring defaults to be
-dependent on a particular configuration greatly inconveniences
-some users of legacy code.
-
-Many users appreciate the GNU compilers because they provide an
-environment that is uniform across machines.
-These users would be
-inconvenienced if the compiler treated things like the
-format of the source code differently on certain machines.
-
-Occasionally users write programs intended only for a particular machine
-type.
-On these occasions, the users would benefit if the GNU Fortran compiler
-were to support by default the same dialect as the other compilers on
-that machine.
-But such applications are rare.
-And users writing a
-program to run on more than one type of machine cannot possibly benefit
-from this kind of compatibility.
-(This is consistent with the design goals for @command{gcc}.
-To change them for @command{g77}, you must first change them
-for @command{gcc}.
-Do not ask the maintainers of @command{g77} to do this for you,
-or to disassociate @command{g77} from the widely understood, if
-not widely agreed-upon, goals for GNU compilers in general.)
-
-This is why GNU Fortran does and will treat backslashes in the same
-fashion on all types of machines (by default).
-@xref{Direction of Language Development}, for more information on
-this overall philosophy guiding the development of the GNU Fortran
-language.
-
-Of course, users strongly concerned about portability should indicate
-explicitly in their build procedures which options are expected
-by their source code, or write source code that has as few such
-expectations as possible.
-
-For example, avoid writing code that depends on backslash (@samp{\})
-being interpreted either way in particular, such as by
-starting a program unit with:
-
-@smallexample
-CHARACTER BACKSL
-PARAMETER (BACKSL = '\\')
-@end smallexample
-
-@noindent
-Then, use concatenation of @samp{BACKSL} anyplace a backslash
-is desired.
-In this way, users can write programs which have the same meaning
-in many Fortran dialects.
-
-(However, this technique does not work for Hollerith constants---which
-is just as well, since the only generally portable uses for Hollerith
-constants are in places where character constants can and should
-be used instead, for readability.)

-@node Initializing Before Specifying
-@subsection Initializing Before Specifying
-@cindex initialization, statement placement
-@cindex placing initialization statements
-
-@command{g77} does not allow @samp{DATA VAR/1/} to appear in the
-source code before @samp{COMMON VAR},
-@samp{DIMENSION VAR(10)}, @samp{INTEGER VAR}, and so on.
-In general, @command{g77} requires initialization of a variable
-or array to be specified @emph{after} all other specifications
-of attributes (type, size, placement, and so on) of that variable
-or array are specified (though @emph{confirmation} of data type is
-permitted).
-
-It is @emph{possible} @command{g77} will someday allow all of this,
-even though it is not allowed by the FORTRAN 77 standard.
-
-Then again, maybe it is better to have
-@command{g77} always require placement of @code{DATA}
-so that it can possibly immediately write constants
-to the output file, thus saving time and space.
-
-That is, @samp{DATA A/1000000*1/} should perhaps always
-be immediately writable to canonical assembler, unless it's already known
-to be in a @code{COMMON} area following as-yet-uninitialized stuff,
-and to do this it cannot be followed by @samp{COMMON A}.
-
-@node Context-Sensitive Intrinsicness
-@subsection Context-Sensitive Intrinsicness
-@cindex intrinsics, context-sensitive
-@cindex context-sensitive intrinsics
-
-@command{g77} treats procedure references to @emph{possible} intrinsic
-names as always enabling their intrinsic nature, regardless of
-whether the @emph{form} of the reference is valid for that
-intrinsic.
-
-For example, @samp{CALL SQRT} is interpreted by @command{g77} as
-an invalid reference to the @code{SQRT} intrinsic function,
-because the reference is a subroutine invocation.
-
-First, @command{g77} recognizes the statement @samp{CALL SQRT}
-as a reference to a @emph{procedure} named @samp{SQRT}, not
-to a @emph{variable} with that name (as it would for a statement
-such as @samp{V = SQRT}).
-
-Next, @command{g77} establishes that, in the program unit being compiled,
-@code{SQRT} is an intrinsic---not a subroutine that
-happens to have the same name as an intrinsic (as would be
-the case if, for example, @samp{EXTERNAL SQRT} was present).
-
-Finally, @command{g77} recognizes that the @emph{form} of the
-reference is invalid for that particular intrinsic.
-That is, it recognizes that it is invalid for an intrinsic
-@emph{function}, such as @code{SQRT}, to be invoked as
-a @emph{subroutine}.
-
-At that point, @command{g77} issues a diagnostic.
-
-Some users claim that it is ``obvious'' that @samp{CALL SQRT}
-references an external subroutine of their own, not an
-intrinsic function.
-
-However, @command{g77} knows about intrinsic
-subroutines, not just functions, and is able to support both having
-the same names, for example.
-
-As a result of this, @command{g77} rejects calls
-to intrinsics that are not subroutines, and function invocations
-of intrinsics that are not functions, just as it (and most compilers)
-rejects invocations of intrinsics with the wrong number (or types)
-of arguments.
-
-So, use the @samp{EXTERNAL SQRT} statement in a program unit that calls
-a user-written subroutine named @samp{SQRT}.
-
-@node Context-Sensitive Constants
-@subsection Context-Sensitive Constants
-@cindex constants, context-sensitive
-@cindex context-sensitive constants
-
-@command{g77} does not use context to determine the types of
-constants or named constants (@code{PARAMETER}), except
-for (non-standard) typeless constants such as @samp{'123'O}.
-
-For example, consider the following statement:
-
-@smallexample
-PRINT *, 9.435784839284958 * 2D0
-@end smallexample
-
-@noindent
-@command{g77} will interpret the (truncated) constant
-@samp{9.435784839284958} as a @code{REAL(KIND=1)}, not @code{REAL(KIND=2)},
-constant, because the suffix @code{D0} is not specified.
-
-As a result, the output of the above statement when
-compiled by @command{g77} will appear to have ``less precision''
-than when compiled by other compilers.
-
-In these and other cases, some compilers detect the
-fact that a single-precision constant is used in
-a double-precision context and therefore interpret the
-single-precision constant as if it was @emph{explicitly}
-specified as a double-precision constant.
-(This has the effect of appending @emph{decimal}, not
-@emph{binary}, zeros to the fractional part of the
-number---producing different computational results.)
-
-The reason this misfeature is dangerous is that a slight,
-apparently innocuous change to the source code can change
-the computational results.
-Consider:
-
-@smallexample
-REAL ALMOST, CLOSE
-DOUBLE PRECISION FIVE
-PARAMETER (ALMOST = 5.000000000001)
-FIVE = 5
-CLOSE = 5.000000000001
-PRINT *, 5.000000000001 - FIVE
-PRINT *, ALMOST - FIVE
-PRINT *, CLOSE - FIVE
-END
-@end smallexample
-
-@noindent
-Running the above program should
-result in the same value being
-printed three times.
-With @command{g77} as the compiler,
-it does.
-
-However, compiled by many other compilers,
-running the above program would print
-two or three distinct values, because
-in two or three of the statements, the
-constant @samp{5.000000000001}, which
-on most systems is exactly equal to @samp{5.}
-when interpreted as a single-precision constant,
-is instead interpreted as a double-precision
-constant, preserving the represented
-precision.
-However, this ``clever'' promotion of
-type does not extend to variables or,
-in some compilers, to named constants.
-
-Since programmers often are encouraged to replace manifest
-constants or permanently-assigned variables with named
-constants (@code{PARAMETER} in Fortran), and might need
-to replace some constants with variables having the same
-values for pertinent portions of code,
-it is important that compilers treat code so modified in the
-same way so that the results of such programs are the same.
-@command{g77} helps in this regard by treating constants just
-the same as variables in terms of determining their types
-in a context-independent way.
-
-Still, there is a lot of existing Fortran code that has
-been written to depend on the way other compilers freely
-interpret constants' types based on context, so anything
-@command{g77} can do to help flag cases of this in such code
-could be very helpful.

-is not supported, except via @option{-fugly-logint}, which is not

-
-Legacy code should be changed, as resources permit, to use @code{.EQV.}
-and @code{.NEQV.} instead, as these are permitted by the various
-Fortran standards.
-
-New code should never be written expecting @code{.EQ.} or @code{.NE.}
-to work if either of its operands is @code{LOGICAL}.
-
-The problem with supporting this ``feature'' is that there is
-unlikely to be consensus on how it works, as illustrated by the
-following sample program:
-
-@smallexample
-LOGICAL L,M,N
-DATA L,M,N /3*.FALSE./
-IF (L.AND.M.EQ.N) PRINT *,'L.AND.M.EQ.N'
-END
-@end smallexample
-
-The issue raised by the above sample program is: what is the
-precedence of @code{.EQ.} (and @code{.NE.}) when applied to
-@code{LOGICAL} operands?
-
-Some programmers will argue that it is the same as the precedence
-for @code{.EQ.} when applied to numeric (such as @code{INTEGER})
-operands.
-By this interpretation, the subexpression @samp{M.EQ.N} must be
-evaluated first in the above program, resulting in a program that,
-when run, does not execute the @code{PRINT} statement.
-
-Other programmers will argue that the precedence is the same as
-the precedence for @code{.EQV.}, which is restricted by the standards
-to @code{LOGICAL} operands.
-By this interpretation, the subexpression @samp{L.AND.M} must be
-evaluated first, resulting in a program that @emph{does} execute
-the @code{PRINT} statement.
-
-Assigning arbitrary semantic interpretations to syntactic expressions
-that might legitimately have more than one ``obvious'' interpretation
-is generally unwise.
-
-The creators of the various Fortran standards have done a good job
-in this case, requiring a distinct set of operators (which have their
-own distinct precedence) to compare @code{LOGICAL} operands.
-This requirement results in expression syntax with more certain
-precedence (without requiring substantial context), making it easier
-for programmers to read existing code.
-@command{g77} will avoid muddying up elements of the Fortran language
-that were well-designed in the first place.
-
-(Ask C programmers about the precedence of expressions such as
-@samp{(a) & (b)} and @samp{(a) - (b)}---they cannot even tell
-you, without knowing more context, whether the @samp{&} and @samp{-}
-operators are infix (binary) or unary!)
-
-Most dangerous of all is the fact that,
-even assuming consensus on its meaning,
-an expression like @samp{L.AND.M.EQ.N},
-if it is the result of a typographical error,
-doesn't @emph{look} like it has such a typo.
-Even experienced Fortran programmers would not likely notice that
-@samp{L.AND.M.EQV.N} was, in fact, intended.
-
-So, this is a prime example of a circumstance in which
-a quality compiler diagnoses the code,
-instead of leaving it up to someone debugging it

-that might diagnose it.

-in the same order as in some other compiler---or even in the same
-order as another version, port, or invocation (using different
-command-line options) of @command{g77}.
-
-It is never safe to depend on the order of evaluation of side effects.
-For example, an expression like this may very well behave differently
-from one compiler to another:
-
-@smallexample
-J = IFUNC() - IFUNC()

-There is no guarantee that @samp{IFUNC} will be evaluated in any particular

-If @samp{IFUNC} returns 5 the first time it is invoked, and

-
-Generally, in Fortran, procedures with side-effects intended to

-in the code you're compiling with @command{g77}:
-
-@itemize @bullet
-@item
-Compile your code using the @command{g77} options @samp{-W -Wall -O}.
-These options enable many useful warning; the @option{-O} option
-enables flow analysis that enables the uninitialized-variable
-warning.
-
-If you investigate the warnings and find evidence of possible bugs
-in your code, fix them first and retry @command{g77}.

-Compile your code using the @command{g77} options @option{-finit-local-zero},
-@option{-fno-automatic}, @option{-ffloat-store}, and various
-combinations thereof.
-
-If your code works with any of these combinations, that is not
-proof that the bug isn't in @command{g77}---a @command{g77} bug exposed
-by your code might simply be avoided, or have a different, more subtle
-effect, when different options are used---but it can be a
-strong indicator that your code is making unwarranted assumptions
-about the Fortran dialect and/or underlying machine it is
-being compiled and run on.

-
-To add a new command-line option to @command{g77}, first decide
-what kind of option you wish to add.
-Search the @command{g77} and @command{gcc} documentation for one
-or more options that is most closely like the one you want to add
-(in terms of what kind of effect it has, and so on) to
-help clarify its nature.
-
-@itemize @bullet
-@item
-@emph{Fortran options} are options that apply only
-when compiling Fortran programs.
-They are accepted by @command{g77} and @command{gcc}, but
-they apply only when compiling Fortran programs.
-
-@item
-@emph{Compiler options} are options that apply
-when compiling most any kind of program.
-@end itemize
-
-@emph{Fortran options} are listed in the file
-@file{@value{path-g77}/lang-options.h},
-which is used during the build of @command{gcc} to
-build a list of all options that are accepted by
-at least one language's compiler.
-This list goes into the @code{documented_lang_options} array
-in @file{gcc/toplev.c}, which uses this array to
-determine whether a particular option should be
-offered to the linked-in front end for processing
-by calling @code{lang_option_decode}, which, for
-@command{g77}, is in @file{@value{path-g77}/com.c} and just
-calls @code{ffe_decode_option}.
-
-If the linked-in front end ``rejects'' a
-particular option passed to it, @file{toplev.c}
-just ignores the option, because @emph{some}
-language's compiler is willing to accept it.
-
-This allows commands like @samp{gcc -fno-asm foo.c bar.f}
-to work, even though Fortran compilation does
-not currently support the @option{-fno-asm} option;
-even though the @code{f771} version of @code{lang_decode_option}
-rejects @option{-fno-asm}, @file{toplev.c} doesn't
-produce a diagnostic because some other language (C)
-does accept it.
-
-This also means that commands like
-@samp{g77 -fno-asm foo.f} yield no diagnostics,
-despite the fact that no phase of the command was
-able to recognize and process @option{-fno-asm}---perhaps
-a warning about this would be helpful if it were
-possible.
-
-Code that processes Fortran options is found in
-@file{@value{path-g77}/top.c}, function @code{ffe_decode_option}.
-This code needs to check positive and negative forms
-of each option.
-
-The defaults for Fortran options are set in their
-global definitions, also found in @file{@value{path-g77}/top.c}.
-Many of these defaults are actually macros defined
-in @file{@value{path-g77}/target.h}, since they might be
-machine-specific.
-However, since, in practice, GNU compilers
-should behave the same way on all configurations
-(especially when it comes to language constructs),
-the practice of setting defaults in @file{target.h}
-is likely to be deprecated and, ultimately, stopped
-in future versions of @command{g77}.
-
-Accessor macros for Fortran options, used by code
-in the @command{g77} FFE, are defined in @file{@value{path-g77}/top.h}.
-
-@emph{Compiler options} are listed in @file{gcc/toplev.c}
-in the array @code{f_options}.
-An option not listed in @code{lang_options} is
-looked up in @code{f_options} and handled from there.
-
-The defaults for compiler options are set in the
-global definitions for the corresponding variables,
-some of which are in @file{gcc/toplev.c}.
-
-You can set different defaults for @emph{Fortran-oriented}
-or @emph{Fortran-reticent} compiler options by changing
-the source code of @command{g77} and rebuilding.
-How to do this depends on the version of @command{g77}:
-
-@table @code
-@item G77 0.5.24 (EGCS 1.1)
-@itemx G77 0.5.25 (EGCS 1.2 - which became GCC 2.95)
-Change the @code{lang_init_options} routine in @file{gcc/gcc/f/com.c}.
-
-(Note that these versions of @command{g77}
-perform internal consistency checking automatically
-when the @option{-fversion} option is specified.)
-
-@item G77 0.5.23
-@itemx G77 0.5.24 (EGCS 1.0)
-Change the way @code{f771} handles the @option{-fset-g77-defaults}
-option, which is always provided as the first option when
-called by @command{g77} or @command{gcc}.
-
-This code is in @code{ffe_decode_options} in @file{@value{path-g77}/top.c}.
-Have it change just the variables that you want to default
-to a different setting for Fortran compiles compared to
-compiles of other languages.
-
-The @option{-fset-g77-defaults} option is passed to @code{f771}
-automatically because of the specification information
-kept in @file{@value{path-g77}/lang-specs.h}.
-This file tells the @command{gcc} command how to recognize,
-in this case, Fortran source files (those to be preprocessed,
-and those that are not), and further, how to invoke the
-appropriate programs (including @code{f771}) to process
-those source files.
-
-It is in @file{@value{path-g77}/lang-specs.h} that @option{-fset-g77-defaults},
-@option{-fversion}, and other options are passed, as appropriate,
-even when the user has not explicitly specified them.
-Other ``internal'' options such as @option{-quiet} also
-are passed via this mechanism.

-
-Don't bother doing any performance analysis until most of the
-following items are taken care of, because there's no question
-they represent serious space/time problems, although some of
-them show up only given certain kinds of (popular) input.
-
-@itemize @bullet
-@item
-Improve @code{malloc} package and its uses to specify more info about
-memory pools and, where feasible, use obstacks to implement them.
-
-@item
-Skip over uninitialized portions of aggregate areas (arrays,
-@code{COMMON} areas, @code{EQUIVALENCE} areas) so zeros need not be output.
-This would reduce memory usage for large initialized aggregate
-areas, even ones with only one initialized element.
-
-As of version 0.5.18, a portion of this item has already been
-accomplished.
-
-@item
-Prescan the statement (in @file{sta.c}) so that the nature of the statement
-is determined as much as possible by looking entirely at its form,
-and not looking at any context (previous statements, including types
-of symbols).
-This would allow ripping out of the statement-confirmation,
-symbol retraction/confirmation, and diagnostic inhibition
-mechanisms.
-Plus, it would result in much-improved diagnostics.
-For example, @samp{CALL some-intrinsic(@dots{})}, where the intrinsic
-is not a subroutine intrinsic, would result actual error instead of the
-unimplemented-statement catch-all.
-
-@item
-Throughout @command{g77}, don't pass line/column pairs where
-a simple @code{ffewhere} type, which points to the error as much as is
-desired by the configuration, will do, and don't pass @code{ffelexToken} types
-where a simple @code{ffewhere} type will do.
-Then, allow new default
-configuration of @code{ffewhere} such that the source line text is not
-preserved, and leave it to things like Emacs' next-error function
-to point to them (now that @samp{next-error} supports column,
-or, perhaps, character-offset, numbers).
-The change in calling sequences should improve performance somewhat,
-as should not having to save source lines.
-(Whether this whole
-item will improve performance is questionable, but it should
-improve maintainability.)
-
-@item
-Handle @samp{DATA (A(I),I=1,1000000)/1000000*2/} more efficiently, especially
-as regards the assembly output.
-Some of this might require improving
-the back end, but lots of improvement in space/time required in @command{g77}
-itself can be fairly easily obtained without touching the back end.
-Maybe type-conversion, where necessary, can be speeded up as well in
-cases like the one shown (converting the @samp{2} into @samp{2.}).
-
-@item
-If analysis shows it to be worthwhile, optimize @file{lex.c}.
-
-@item
-Consider redesigning @file{lex.c} to not need any feedback
-during tokenization, by keeping track of enough parse state on its
-own.

-
-Much of this work should be put off until after @command{g77} has
-all the features necessary for its widespread acceptance as a
-useful F77 compiler.
-However, perhaps this work can be done in parallel during
-the feature-adding work.
-
-@itemize @bullet
-@item
-Do the equivalent of the trick of putting @samp{extern inline} in front
-of every function definition in @code{libg2c} and #include'ing the resulting
-file in @command{f2c}+@command{gcc}---that is, inline all run-time-library functions
-that are at all worth inlining.
-(Some of this has already been done, such as for integral exponentiation.)
-
-@item
-When doing @samp{CHAR_VAR = CHAR_FUNC(@dots{})},
-and it's clear that types line up
-and @samp{CHAR_VAR} is addressable or not a @code{VAR_DECL},
-make @samp{CHAR_VAR}, not a
-temporary, be the receiver for @samp{CHAR_FUNC}.
-(This is now done for @code{COMPLEX} variables.)
-
-@item
-Design and implement Fortran-specific optimizations that don't
-really belong in the back end, or where the front end needs to
-give the back end more info than it currently does.
-
-@item
-Design and implement a new run-time library interface, with the
-code going into @code{libgcc} so no special linking is required to
-link Fortran programs using standard language features.
-This library
-would speed up lots of things, from I/O (using precompiled formats,
-doing just one, or, at most, very few, calls for arrays or array sections,
-and so on) to general computing (array/section implementations of
-various intrinsics, implementation of commonly performed loops that
-aren't likely to be optimally compiled otherwise, etc.).
-
-Among the important things the library would do are:
-
-@itemize @bullet
-@item
-Be a one-stop-shop-type
-library, hence shareable and usable by all, in that what are now
-library-build-time options in @code{libg2c} would be moved at least to the
-@command{g77} compile phase, if not to finer grains (such as choosing how
-list-directed I/O formatting is done by default at @code{OPEN} time, for
-preconnected units via options or even statements in the main program
-unit, maybe even on a per-I/O basis with appropriate pragma-like
-devices).
-@end itemize
-
-@item
-Probably requiring the new library design, change interface to
-normally have @code{COMPLEX} functions return their values in the way
-@command{gcc} would if they were declared @code{__complex__ float},
-rather than using
-the mechanism currently used by @code{CHARACTER} functions (whereby the
-functions are compiled as returning void and their first arg is
-a pointer to where to store the result).
-(Don't append underscores to
-external names for @code{COMPLEX} functions in some cases once @command{g77} uses
-@command{gcc} rather than @command{f2c} calling conventions.)
-
-@item
-Do something useful with @code{doiter} references where possible.
-For example, @samp{CALL FOO(I)} cannot modify @samp{I} if within
-a @code{DO} loop that uses @samp{I} as the
-iteration variable, and the back end might find that info useful
-in determining whether it needs to read @samp{I} back into a register after
-the call.
-(It normally has to do that, unless it knows @samp{FOO} never
-modifies its passed-by-reference argument, which is rarely the case
-for Fortran-77 code.)

-
-Making @command{g77} easier to configure, port, build, and install, either
-as a single-system compiler or as a cross-compiler, would be
-very useful.
-
-@itemize @bullet
-@item
-A new library (replacing @code{libg2c}) should improve portability as well as
-produce more optimal code.
-Further, @command{g77} and the new library should
-conspire to simplify naming of externals, such as by removing unnecessarily
-added underscores, and to reduce/eliminate the possibility of naming
-conflicts, while making debugger more straightforward.
-
-Also, it should
-make multi-language applications more feasible, such as by providing
-Fortran intrinsics that get Fortran unit numbers given C @code{FILE *}
-descriptors.
-
-@item
-Possibly related to a new library, @command{g77} should produce the equivalent
-of a @command{gcc} @samp{main(argc, argv)} function when it compiles a
-main program unit, instead of compiling something that must be
-called by a library
-implementation of @code{main()}.
-
-This would do many useful things such as
-provide more flexibility in terms of setting up exception handling,
-not requiring programmers to start their debugging sessions with
-@kbd{breakpoint MAIN__} followed by @kbd{run}, and so on.
-
-@item
-The GBE needs to understand the difference between alignment
-requirements and desires.
-For example, on Intel x86 machines, @command{g77} currently imposes
-overly strict alignment requirements, due to the back end, but it
-would be useful for Fortran and C programmers to be able to override
-these @emph{recommendations} as long as they don't violate the actual

-It is not worth repeating them here.
-
-@item
-Consider adding a @code{NUMERIC} type to designate typeless numeric constants,
-named and unnamed.
-The idea is to provide a forward-looking, effective
-replacement for things like the old-style @code{PARAMETER} statement
-when people
-really need typelessness in a maintainable, portable, clearly documented
-way.
-Maybe @code{TYPELESS} would include @code{CHARACTER}, @code{POINTER},
-and whatever else might come along.
-(This is not really a call for polymorphism per se, just
-an ability to express limited, syntactic polymorphism.)
-
-@item
-Support @samp{OPEN(@dots{},KEY=(@dots{}),@dots{})}.
-
-@item
-Support arbitrary file unit numbers, instead of limiting them
-to 0 through @samp{MXUNIT-1}.
-(This is a @code{libg2c} issue.)
-
-@item
-@samp{OPEN(NOSPANBLOCKS,@dots{})} is treated as
-@samp{OPEN(UNIT=NOSPANBLOCKS,@dots{})}, so a
-later @code{UNIT=} in the first example is invalid.
-Make sure this is what users of this feature would expect.
-
-@item
-Currently @command{g77} disallows @samp{READ(1'10)} since
-it is an obnoxious syntax, but
-supporting it might be pretty easy if needed.
-More details are needed, such
-as whether general expressions separated by an apostrophe are supported,
-or maybe the record number can be a general expression, and so on.
-
-@item
-Support @code{STRUCTURE}, @code{UNION}, @code{MAP}, and @code{RECORD}
-fully.
-Currently there is no support at all
-for @code{%FILL} in @code{STRUCTURE} and related syntax,
-whereas the rest of the
-stuff has at least some parsing support.
-This requires either major
-changes to @code{libg2c} or its replacement.

-F90 and @command{g77} probably disagree about label scoping relative to

-Empty-statement handling (10 ;;CONTINUE;;) probably isn't consistent
-with the final form of the standard (it was vague at S8.112).
-
-@item
-It seems to be an ``open'' question whether a file, immediately after being
-@code{OPEN}ed,is positioned at the beginning, the end, or wherever---it
-might be nice to offer an option of opening to ``undefined'' status, requiring

-

-Utility to read and check @file{bad.def} messages and their references in the

-
-@item
-Search and fix @samp{&ffe@dots{}} and similar so that
-@samp{ffe@dots{}ptr@dots{}} macros are
-available instead (a good argument for wishing this could have written all
-this stuff in C++, perhaps).
-On the other hand, it's questionable whether this sort of
-improvement is really necessary, given the availability of
-tools such as Emacs and Perl, which make finding any
-address-taking of structure members easy enough?
-

-Some modules truly export the member names of their structures (and the

-in @file{proj.h}
-and use them throughout @command{g77} source code (especially in the definitions

-Some diagnostics produced by @command{g77} require sufficient explanation
-that the explanations are given below, and the diagnostics themselves
-identify the appropriate explanation.
-
-Identification uses the GNU Info format---specifically, the @command{info}
-command that displays the explanation is given within square
-brackets in the diagnostic.
-For example:
-
-@smallexample
-foo.f:5: Invalid statement [info -f g77 M FOOEY]
-@end smallexample
-
-More details about the above diagnostic is found in the @command{g77} Info
-documentation, menu item @samp{M}, submenu item @samp{FOOEY},
-which is displayed by typing the UNIX command
-@samp{info -f g77 M FOOEY}.
-
-Other Info readers, such as EMACS, may be just as easily used to display
-the pertinent node.
-In the above example, @samp{g77} is the Info document name,
-@samp{M} is the top-level menu item to select,
-and, in that node (named @samp{Diagnostics}, the name of

-Ambiguous use of intrinsic @var{intrinsic} @dots{}
-@end smallexample
-
-The type of the argument to the invocation of the @var{intrinsic}
-intrinsic is a @code{COMPLEX} type other than @code{COMPLEX(KIND=1)}.
-Typically, it is @code{COMPLEX(KIND=2)}, also known as
-@code{DOUBLE COMPLEX}.
-
-The interpretation of this invocation depends on the particular
-dialect of Fortran for which the code was written.
-Some dialects convert the real part of the argument to
-@code{REAL(KIND=1)}, thus losing precision; other dialects,
-and Fortran 90, do no such conversion.
-
-So, GNU Fortran rejects such invocations except under certain
-circumstances, to avoid making an incorrect assumption that results
-in generating the wrong code.
-
-To determine the dialect of the program unit, perhaps even whether
-that particular invocation is properly coded, determine how the
-result of the intrinsic is used.
-
-The result of @var{intrinsic} is expected (by the original programmer)
-to be @code{REAL(KIND=1)} (the non-Fortran-90 interpretation) if:
-
-@itemize @bullet
-@item
-It is passed as an argument to a procedure that explicitly or
-implicitly declares that argument @code{REAL(KIND=1)}.
-
-For example,
-a procedure with no @code{DOUBLE PRECISION} or @code{IMPLICIT DOUBLE PRECISION}
-statement specifying the dummy argument corresponding to an
-actual argument of @samp{REAL(Z)}, where @samp{Z} is declared
-@code{DOUBLE COMPLEX}, strongly suggests that the programmer
-expected @samp{REAL(Z)} to return @code{REAL(KIND=1)} instead
-of @code{REAL(KIND=2)}.
-
-@item
-It is used in a context that would otherwise not include
-any @code{REAL(KIND=2)} but where treating the @var{intrinsic}
-invocation as @code{REAL(KIND=2)} would result in unnecessary
-promotions and (typically) more expensive operations on the
-wider type.
-
-For example:
-
-@smallexample
-DOUBLE COMPLEX Z
-@dots{}
-R(1) = T * REAL(Z)
-@end smallexample
-
-The above example suggests the programmer expected the real part
-of @samp{Z} to be converted to @code{REAL(KIND=1)} before being
-multiplied by @samp{T} (presumed, along with @samp{R} above, to
-be type @code{REAL(KIND=1)}).
-
-Otherwise, the conversion would have to be delayed until after
-the multiplication, requiring not only an extra conversion
-(of @samp{T} to @code{REAL(KIND=2)}), but a (typically) more
-expensive multiplication (a double-precision multiplication instead
-of a single-precision one).
-@end itemize
-
-The result of @var{intrinsic} is expected (by the original programmer)
-to be @code{REAL(KIND=2)} (the Fortran 90 interpretation) if:
-
-@itemize @bullet
-@item
-It is passed as an argument to a procedure that explicitly or
-implicitly declares that argument @code{REAL(KIND=2)}.
-
-For example, a procedure specifying a @code{DOUBLE PRECISION}
-dummy argument corresponding to an
-actual argument of @samp{REAL(Z)}, where @samp{Z} is declared
-@code{DOUBLE COMPLEX}, strongly suggests that the programmer
-expected @samp{REAL(Z)} to return @code{REAL(KIND=2)} instead
-of @code{REAL(KIND=1)}.
-
-@item
-It is used in an expression context that includes
-other @code{REAL(KIND=2)} operands,
-or is assigned to a @code{REAL(KIND=2)} variable or array element.
-
-For example:
-
-@smallexample
-DOUBLE COMPLEX Z
-DOUBLE PRECISION R, T
-@dots{}
-R(1) = T * REAL(Z)
-@end smallexample
-
-The above example suggests the programmer expected the real part
-of @samp{Z} to @emph{not} be converted to @code{REAL(KIND=1)}
-by the @code{REAL()} intrinsic.
-
-Otherwise, the conversion would have to be immediately followed
-by a conversion back to @code{REAL(KIND=2)}, losing
-the original, full precision of the real part of @code{Z},
-before being multiplied by @samp{T}.
-@end itemize
-
-Once you have determined whether a particular invocation of @var{intrinsic}
-expects the Fortran 90 interpretation, you can:
-
-@itemize @bullet
-@item
-Change it to @samp{DBLE(@var{expr})} (if @var{intrinsic} is
-@code{REAL}) or @samp{DIMAG(@var{expr})} (if @var{intrinsic}
-is @code{AIMAG})
-if it expected the Fortran 90 interpretation.
-
-This assumes @var{expr} is @code{COMPLEX(KIND=2)}---if it is
-some other type, such as @code{COMPLEX*32}, you should use the
-appropriate intrinsic, such as the one to convert to @code{REAL*16}
-(perhaps @code{DBLEQ()} in place of @code{DBLE()}, and
-@code{QIMAG()} in place of @code{DIMAG()}).
-
-@item
-Change it to @samp{REAL(@var{intrinsic}(@var{expr}))},
-otherwise.
-This converts to @code{REAL(KIND=1)} in all working
-Fortran compilers.
-@end itemize
-
-If you don't want to change the code, and you are certain that all
-ambiguous invocations of @var{intrinsic} in the source file have
-the same expectation regarding interpretation, you can:
-
-@itemize @bullet
-@item
-Compile with the @command{g77} option @option{-ff90}, to enable the
-Fortran 90 interpretation.
-
-@item
-Compile with the @command{g77} options @samp{-fno-f90 -fugly-complex},
-to enable the non-Fortran-90 interpretations.
-@end itemize
-
-@xref{REAL() and AIMAG() of Complex}, for more information on this
-issue.
-
-Note: If the above suggestions don't produce enough evidence
-as to whether a particular program expects the Fortran 90
-interpretation of this ambiguous invocation of @var{intrinsic},
-there is one more thing you can try.
-
-If you have access to most or all the compilers used on the
-program to create successfully tested and deployed executables,
-read the documentation for, and @emph{also} test out, each compiler
-to determine how it treats the @var{intrinsic} intrinsic in

-(If all the compilers don't agree on an interpretation, there
-might be lurking bugs in the deployed versions of the program.)

-The @var{intrinsic} is explicitly declared in one program

-in another program unit in the same source file.
-
-This diagnostic is designed to catch cases where a program
-might depend on using the name @var{intrinsic} as an intrinsic
-in one program unit and as a global name (such as the name

-
-This and related warnings are disabled by using

-
-Note that this warning is not issued for standard intrinsics.
-Standard intrinsics include those described in the FORTRAN 77

-
-The name @var{intrinsic} is used for a global entity (a common
-block or a program unit) in one program unit and implicitly
-used as an intrinsic in another program unit.
-
-This diagnostic is designed to catch cases where a program
-intends to use a name entirely as a global name, but @command{g77}
-recognizes the name as an intrinsic in the program unit that
-references the name, a situation that would likely produce
-incorrect code.
-
-For example:
-
-@smallexample
-INTEGER FUNCTION TIME()
-@dots{}
-END
-@dots{}
-PROGRAM SAMP
-INTEGER TIME
-PRINT *, 'Time is ', TIME()
-END
-@end smallexample
-
-The above example defines a program unit named @samp{TIME}, but
-the reference to @samp{TIME} in the main program unit @samp{SAMP}
-is normally treated by @command{g77} as a reference to the intrinsic
-@code{TIME()} (unless a command-line option that prevents such
-treatment has been specified).
-
-As a result, the program @samp{SAMP} will @emph{not}
-invoke the @samp{TIME} function in the same source file.
-
-Since @command{g77} recognizes @code{libU77} procedures as
-intrinsics, and since some existing code uses the same names
-for its own procedures as used by some @code{libU77}
-procedures, this situation is expected to arise often enough
-to make this sort of warning worth issuing.
-
-After verifying that the program unit making implicit use
-of the intrinsic is indeed written expecting the intrinsic,
-add an @samp{INTRINSIC @var{intrinsic}} statement to that
-program unit to prevent this warning.
-
-Or, if you believe the program unit is designed to invoke the
-program-defined procedure instead of the intrinsic (as
-recognized by @command{g77}), add an @samp{EXTERNAL @var{intrinsic}}
-statement to the program unit that references the name to
-prevent this warning.
-
-This and related warnings are disabled by using
-the @option{-Wno-globals} option when compiling.
-
-Note that this warning is not issued for standard intrinsics.
-Standard intrinsics include those described in the FORTRAN 77

-Although the diagnostics identify specific problems, they can
-be produced when general problems such as the following occur:
-
-@itemize @bullet
-@item
-The source file contains something other than Fortran code.
-
-If the code in the file does not look like many of the examples
-elsewhere in this document, it might not be Fortran code.
-(Note that Fortran code often is written in lower case letters,
-while the examples in this document use upper case letters,
-for stylistic reasons.)
-
-For example, if the file contains lots of strange-looking
-characters, it might be APL source code; if it contains lots
-of parentheses, it might be Lisp source code; if it
-contains lots of bugs, it might be C++ source code.
-
-@item
-The source file contains free-form Fortran code, but @option{-ffree-form}
-was not specified on the command line to compile it.
-
-Free form is a newer form for Fortran code.
-The older, classic form is called fixed form.
-
-@cindex continuation character
-@cindex characters, continuation
-Fixed-form code is visually fairly distinctive, because
-numerical labels and comments are all that appear in
-the first five columns of a line, the sixth column is
-reserved to denote continuation lines,
-and actual statements start at or beyond column 7.
-Spaces generally are not significant, so if you
-see statements such as @samp{REALX,Y} and @samp{DO10I=1,100},
-you are looking at fixed-form code.
-@cindex *
-@cindex asterisk
-Comment lines are indicated by the letter @samp{C} or the symbol
-@samp{*} in column 1.
-@cindex trailing comment
-@cindex comment
-@cindex characters, comment
-@cindex !
-@cindex exclamation point
-(Some code uses @samp{!} or @samp{/*} to begin in-line comments,
-which many compilers support.)
-
-Free-form code is distinguished from fixed-form source
-primarily by the fact that statements may start anywhere.
-(If lots of statements start in columns 1 through 6,
-that's a strong indicator of free-form source.)
-Consecutive keywords must be separated by spaces, so
-@samp{REALX,Y} is not valid, while @samp{REAL X,Y} is.
-There are no comment lines per se, but @samp{!} starts a
-comment anywhere in a line (other than within a character or
-Hollerith constant).
-
-@xref{Source Form}, for more information.
-
-@item
-The source file is in fixed form and has been edited without
-sensitivity to the column requirements.
-
-Statements in fixed-form code must be entirely contained within
-columns 7 through 72 on a given line.
-Starting them ``early'' is more likely to result in diagnostics
-than finishing them ``late'', though both kinds of errors are
-often caught at compile time.
-
-For example, if the following code fragment is edited by following
-the commented instructions literally, the result, shown afterward,
-would produce a diagnostic when compiled:
-
-@smallexample
-C On XYZZY systems, remove "C" on next line:
-C CALL XYZZY_RESET
-@end smallexample
-
-The result of editing the above line might be:
-
-@smallexample
-C On XYZZY systems, remove "C" on next line:
- CALL XYZZY_RESET
-@end smallexample
-
-However, that leaves the first @samp{C} in the @code{CALL}
-statement in column 6, making it a comment line, which is
-not really what the author intended, and which is likely
-to result in one of the above-listed diagnostics.
-
-@emph{Replacing} the @samp{C} in column 1 with a space
-is the proper change to make, to ensure the @code{CALL}
-keyword starts in or after column 7.
-
-Another common mistake like this is to forget that fixed-form
-source lines are significant through only column 72, and that,
-normally, any text beyond column 72 is ignored or is diagnosed
-at compile time.
-
-@xref{Source Form}, for more information.
-
-@item
-The source file requires preprocessing, and the preprocessing
-is not being specified at compile time.
-
-A source file containing lines beginning with @code{#define},
-@code{#include}, @code{#if}, and so on is likely one that
-requires preprocessing.
-
-If the file's suffix is @samp{.f}, @samp{.for}, or @samp{.FOR},
-the file normally will be compiled @emph{without} preprocessing
-by @command{g77}.
-
-Change the file's suffix from @samp{.f} to @samp{.F}
-(or, on systems with case-insensitive file names,
-to @samp{.fpp} or @samp{.FPP}),
-from @samp{.for} to @samp{.fpp},
-or from @samp{.FOR} to @samp{.FPP}.

-
-These messages all identify disagreements about the
-global procedure named @var{name} among different program units
-(usually including @var{name} itself).
-
-Whether a particular disagreement is reported
-as a warning or an error
-can depend on the relative order
-of the disagreeing portions of the source file.
-
-Disagreements between a procedure invocation
-and the @emph{subsequent} procedure itself
-are, usually, diagnosed as errors
-when the procedure itself @emph{precedes} the invocation.
-Other disagreements are diagnosed via warnings.
-
-@cindex forward references
-@cindex in-line code
-@cindex compilation, in-line
-This distinction, between warnings and errors,
-is due primarily to the present tendency of the @command{gcc} back end
-to inline only those procedure invocations that are
-@emph{preceded} by the corresponding procedure definitions.
-If the @command{gcc} back end is changed
-to inline ``forward references'',
-in which invocations precede definitions,
-the @command{g77} front end will be changed
-to treat both orderings as errors, accordingly.
-
-The sorts of disagreements that are diagnosed by @command{g77} include
-whether a procedure is a subroutine or function;
-if it is a function, the type of the return value of the procedure;
-the number of arguments the procedure accepts;
-and the type of each argument.
-
-Disagreements regarding global names among program units
-in a Fortran program @emph{should} be fixed in the code itself.
-However, if that is not immediately practical,
-and the code has been working for some time,
-it is possible it will work
-when compiled with the @option{-fno-globals} option.
-
-The @option{-fno-globals} option
-causes these diagnostics to all be warnings
-and disables all inlining of references to global procedures
-(to avoid subsequent compiler crashes and bad-code generation).
-Use of the @option{-Wno-globals} option as well as @option{-fno-globals}
-suppresses all of these diagnostics.
-(@option{-Wno-globals} by itself disables only the warnings,
-not the errors.)
-
-After using @option{-fno-globals} to work around these problems,
-it is wise to stop using that option and address them by fixing
-the Fortran code, because such problems, while they might not
-actually result in bugs on some systems, indicate that the code
-is not as portable as it could be.
-In particular, the code might appear to work on a particular
-system, but have bugs that affect the reliability of the data
-without exhibiting any other outward manifestations of the bugs.
-

- the linking phase is present, or if `-xfoo' is in effect. Note that
- a lack of source files or -l options disables linking.

- This program was originally made out of gcc/cp/g++spec.c, but the
- way it builds the new argument list was rewritten so it is much
- easier to maintain, improve the way it decides to add or not add
- extra arguments, etc. And several improvements were made in the
- handling of arguments, primarily to make it more consistent with

- DEFDOC (IMP, SUMMARY, DESCRIPTION)
-
- IMP is the implementation keyword used in the intrin module.
- SUMMARY is the short summary to go in the "* Menu:" section
- of the Info document. DESCRIPTION is the longer description
- to go in the documentation itself.
-
- Note that IMP is leveraged across multiple intrinsic names.
-
- To make for more accurate and consistent documentation,
- the translation made by intdoc.c of the text in SUMMARY
- and DESCRIPTION includes the special sequence
-
- @ARGNO@
-
- where ARGNO is a series of digits forming a number that
- is substituted by intdoc.c as follows:
-
- 0 The initial-caps form of the intrinsic name (e.g. Float).
- 1-98 The initial-caps form of the ARGNO'th argument.
- 99 (SUMMARY only) a newline plus the appropriate # of spaces.
-
- Hope this info is enough to encourage people to feel free to
- add documentation to this file!

-argument to the @code{CMPLX()} intrinsic).
-
-(@samp{CMPLX(0D0, 0D0)} returns a single-precision
-@code{COMPLEX} result, as required by standard FORTRAN 77.
-That's why so many compilers provide @code{DCMPLX()}, since
-@samp{DCMPLX(0D0, 0D0)} returns a @code{DOUBLE COMPLEX}
-result.
-Still, @code{DCMPLX()} converts even @code{REAL*16} arguments
-to their @code{REAL*8} equivalents in most dialects of
-Fortran, so neither it nor @code{CMPLX()} allow easy
-construction of arbitrary-precision values without
-potentially forcing a conversion involving extending or

-/* Intrinsic implementations ordered in two sections:
- F77, then extensions; secondarily, alphabetical
- ordering. */
-
-/* The DEFIMP macro specifies the following fields for an intrinsic:
-
- CODE -- The internal name for this intrinsic; `FFEINTRIN_imp'
- prepends this to form the `enum' name.
-
- NAME -- The textual name to use when printing information on
- this intrinsic.
-
- GFRTDIRECT -- The run-time library routine that is suitable for
- a call to implement a *direct* invocation of the
- intrinsic (e.g. `ABS(10)').
-
- GFRTF2C -- The run-time library routine that is suitable for
- passing as an argument to a procedure that will
- invoke the argument as an EXTERNAL procedure, when
- f2c calling conventions will be used (e.g.
- `CALL FOO(ABS)', when FOO compiled with -ff2c).
-
- GFRTGNU -- The run-time library routine that is suitable for
- passing as an argument to a procedure that will
- invoke the argument as an EXTERNAL procedure, when
- GNU calling conventions will be used (e.g.
- `CALL FOO(ABS)', when FOO compiled with -fno-f2c).
-
- CONTROL -- A control string, described below.
-
- The DEFIMPY macro specifies the above, plus:
-
- Y2KBAD -- TRUE if the intrinsic is known to be non-Y2K-compliant,
- FALSE if it is known to be Y2K-compliant. (In terms of
- interface and libg2c implementation.)
-

-
-/* The control string has the following format:
-

-
- <return-base-type> is:
-
- - Subroutine
- A Character
- C Complex
- I Integer
- L Logical
- R Real
- B Boolean (I or L), decided by co-operand list (COL)
- F Floating-point (C or R), decided by COL
- N Numeric (C, I, or R), decided by co-operand list (COL)
- S Scalar numeric (I or R), decided by COL, which may be COMPLEX

- <name>=[<optionality>]<arg-base-type><arg-kind-type>[<arg-len>][<arg-rank>][<arg-extra>]
-
- <name> is the standard keyword name for the argument.
-
- <optionality> is:
-
- ? Argument is optional
- ! Like ?, but argument must be omitted if previous arg was COMPLEX
- + One or more of these arguments must be specified
- * Zero or more of these arguments must be specified
- n Numbered names for arguments, one or more must be specified
- p Like n, but two or more must be specified
-
- <arg-base-type> is:

- C Complex
- I Integer
- L Logical
- R Real
- B Boolean (I or L)
- F Floating-point (C or R)
- N Numeric (C, I, or R)
- S Scalar numeric (I or R)
- g GOTO label (alternate-return form of CALL) (arg-kind-type is 0)
- s Signal handler (INTEGER FUNCTION, SUBROUTINE or dummy/global
- default INTEGER variable) (arg-kind-type is 0)
-
- <arg-kind-type> is:
-
- * Any is valid
- 1 (Default)
- 2 (Twice the size of 1)
- 3 (Same size as CHARACTER*1)
- 4 (Twice the size of 2)

- A Same as first argument
- N Not wider than the default kind
-
- <arg-len> is:
-
- (Default) CHARACTER*(*)
- [n] CHARACTER*n
-
- <arg-rank> is:
-
- (default) Rank-0 (variable or array element)
- (n) Rank-1 array n elements long
- & Any (arg-extra is &)
-
- <arg-extra> is:
-
- (default) Arg is INTENT(IN)
- i Arg's attributes are all that matter (inquiry function)

-
-@c man begin DESCRIPTION
-
-The @command{g77} command supports all the options supported by the
-@command{gcc} command.
-@xref{Invoking GCC,,GCC Command Options,gcc,Using the GNU Compiler
-Collection (GCC)}, for information
-on the non-Fortran-specific aspects of the @command{gcc} command (and,
-therefore, the @command{g77} command).
-
-@cindex options, negative forms
-@cindex negative forms of options
-All @command{gcc} and @command{g77} options
-are accepted both by @command{g77} and by @command{gcc}
-(as well as any other drivers built at the same time,
-such as @command{g++}),
-since adding @command{g77} to the @command{gcc} distribution
-enables acceptance of @command{g77} options
-by all of the relevant drivers.
-
-In some cases, options have positive and negative forms;
-the negative form of @option{-ffoo} would be @option{-fno-foo}.
-This manual documents only one of these two forms, whichever
-one is not the default.
-
-@c man end
-
-@menu
-* Option Summary:: Brief list of all @command{g77} options,
- without explanations.
-* Overall Options:: Controlling the kind of output:
- an executable, object files, assembler files,
- or preprocessed source.
-* Shorthand Options:: Options that are shorthand for other options.
-* Fortran Dialect Options:: Controlling the variant of Fortran language
- compiled.
-* Warning Options:: How picky should the compiler be?
-* Debugging Options:: Symbol tables, measurements, and debugging dumps.
-* Optimize Options:: How much optimization?
-* Preprocessor Options:: Controlling header files and macro definitions.

-Compilation can involve as many as four stages: preprocessing, code
-generation (often what is really meant by the term ``compilation''),
-assembly, and linking, always in that order. The first three
-stages apply to an individual source file, and end by producing an
-object file; linking combines all the object files (those newly
-compiled, and those specified as input) into an executable file.

-@cindex suffixes, file name
-@cindex file name extension
-@cindex extensions, file name
-@cindex file type
-@cindex types, file
-For any given input file, the file name suffix determines what kind of
-program is contained in the file---that is, the language in which the
-program is written is generally indicated by the suffix.
-Suffixes specific to GNU Fortran are listed below.
-@xref{Overall Options,,Options Controlling the Kind of
-Output,gcc,Using the GNU Compiler Collection (GCC)}, for
-information on suffixes recognized by GCC.

-Fortran source code that should not be preprocessed.
-
-Such source code cannot contain any preprocessor directives, such
-as @code{#include}, @code{#define}, @code{#if}, and so on.

-You can force @samp{.f} files to be preprocessed by @command{cpp} by using

-Fortran source code that must be preprocessed (by the C preprocessor
-@command{cpp}, which is part of GCC).
-
-Note that preprocessing is not extended to the contents of
-files included by the @code{INCLUDE} directive---the @code{#include}
-preprocessor directive must be used instead.
-
-@cindex Ratfor preprocessor
-@cindex programs, @command{ratfor}
-@cindex @samp{.r} filename suffix
-@cindex @command{ratfor}
-@item @var{file}.r
-Ratfor source code, which must be preprocessed by the @command{ratfor}
-command, which is available separately (as it is not yet part of the GNU
-Fortran distribution).
-A public domain version in C is at
-@uref{http://sepwww.stanford.edu/sep/prof/ratfor.shar.2}.
-@end table
-
-UNIX users typically use the @file{@var{file}.f} and @file{@var{file}.F}
-nomenclature.
-Users of other operating systems, especially those that cannot
-distinguish upper-case
-letters from lower-case letters in their file names, typically use
-the @file{@var{file}.for} and @file{@var{file}.fpp} nomenclature.
-
-@cindex #define
-@cindex #include
-@cindex #if
-Use of the preprocessor @command{cpp} allows use of C-like
-constructs such as @code{#define} and @code{#include}, but can
-lead to unexpected, even mistaken, results due to Fortran's source file
-format.
-It is recommended that use of the C preprocessor
-be limited to @code{#include} and, in
-conjunction with @code{#define}, only @code{#if} and related directives,
-thus avoiding in-line macro expansion entirely.
-This recommendation applies especially
-when using the traditional fixed source form.
-With free source form,
-fewer unexpected transformations are likely to happen, but use of
-constructs such as Hollerith and character constants can nevertheless
-present problems, especially when these are continued across multiple
-source lines.
-These problems result, primarily, from differences between the way
-such constants are interpreted by the C preprocessor and by a Fortran
-compiler.
-
-Another example of a problem that results from using the C preprocessor
-is that a Fortran comment line that happens to contain any
-characters ``interesting'' to the C preprocessor,
-such as a backslash at the end of the line,
-is not recognized by the preprocessor as a comment line,
-so instead of being passed through ``raw'',
-the line is edited according to the rules for the preprocessor.
-For example, the backslash at the end of the line is removed,
-along with the subsequent newline, resulting in the next
-line being effectively commented out---unfortunate if that
-line is a non-comment line of important code!
-
-@emph{Note:} The @option{-traditional} and @option{-undef} flags are supplied
-to @command{cpp} by default, to help avoid unpleasant surprises.
-@xref{Preprocessor Options,,Options Controlling the Preprocessor,
-gcc,Using the GNU Compiler Collection (GCC)}.
-This means that ANSI C preprocessor features (such as the @samp{#}
-operator) aren't available, and only variables in the C reserved
-namespace (generally, names with a leading underscore) are liable to
-substitution by C predefines.
-Thus, if you want to do system-specific
-tests, use, for example, @samp{#ifdef __linux__} rather than @samp{#ifdef linux}.
-Use the @option{-v} option to see exactly how the preprocessor is invoked.
-
-@cindex /*
-Unfortunately, the @option{-traditional} flag will not avoid an error from
-anything that @command{cpp} sees as an unterminated C comment, such as:
-@smallexample
-C Some Fortran compilers accept /* as starting
-C an inline comment.
-@end smallexample
-@xref{Trailing Comment}.
-
-The following options that affect overall processing are recognized
-by the @command{g77} and @command{gcc} commands in a GNU Fortran installation:

-@cindex printing version information
-@cindex version information, printing
-@cindex consistency checks
-@cindex internal consistency checks
-@cindex checks, of internal consistency
-@item -fversion
-Ensure that the @command{g77} version of the compiler phase is reported,
-if run,
-and, starting in @code{egcs} version 1.1,
-that internal consistency checks in the @file{f771} program are run.
-
-This option is supplied automatically when @option{-v} or @option{--verbose}
-is specified as a command-line option for @command{g77} or @command{gcc}
-and when the resulting commands compile Fortran source files.
-
-In GCC 3.1, this is changed back to the behavior @command{gcc} displays
-for @samp{.c} files.
-
-@cindex -fset-g77-defaults option
-@cindex options, -fset-g77-defaults
-@item -fset-g77-defaults
-@emph{Version info:}
-This option was obsolete as of @code{egcs}
-version 1.1.
-The effect is instead achieved
-by the @code{lang_init_options} routine
-in @file{gcc/gcc/f/com.c}.
-
-@cindex consistency checks
-@cindex internal consistency checks
-@cindex checks, of internal consistency
-Set up whatever @command{gcc} options are to apply to Fortran
-compilations, and avoid running internal consistency checks
-that might take some time.
-
-This option is supplied automatically when compiling Fortran code
-via the @command{g77} or @command{gcc} command.
-The description of this option is provided so that users seeing
-it in the output of, say, @samp{g77 -v} understand why it is
-there.
-
-@cindex modifying @command{g77}
-@cindex @command{g77}, modifying
-Also, developers who run @code{f771} directly might want to specify it
-by hand to get the same defaults as they would running @code{f771}
-via @command{g77} or @command{gcc}
-However, such developers should, after linking a new @code{f771}
-executable, invoke it without this option once,
-e.g. via @kbd{./f771 -quiet < /dev/null},
-to ensure that they have not introduced any
-internal inconsistencies (such as in the table of
-intrinsics) before proceeding---@command{g77} will crash
-with a diagnostic if it detects an inconsistency.

-@cindex backslash
-@cindex character constants
-@cindex Hollerith constants
-Specify that @samp{\} is not to be specially interpreted in character
-and Hollerith constants a la C and many UNIX Fortran compilers.
-
-For example, with @option{-fbackslash} in effect, @samp{A\nB} specifies
-three characters, with the second one being newline.
-With @option{-fno-backslash}, it specifies four characters,
-@samp{A}, @samp{\}, @samp{n}, and @samp{B}.
-
-Note that @command{g77} implements a fairly general form of backslash
-processing that is incompatible with the narrower forms supported
-by some other compilers.
-For example, @samp{'A\003B'} is a three-character string in @command{g77}
-whereas other compilers that support backslash might not support
-the three-octal-digit form, and thus treat that string as longer
-than three characters.

-
-@cindex -fugly-assumed option
-@cindex options, -fugly-assumed
-@item -fugly-assumed
-Assume any dummy array with a final dimension specified as @samp{1}
-is really an assumed-size array, as if @samp{*} had been specified
-for the final dimension instead of @samp{1}.
-
-For example, @samp{DIMENSION X(1)} is treated as if it
-had read @samp{DIMENSION X(*)}.
-
-@xref{Ugly Assumed-Size Arrays}, for more information.
-
-@cindex -fugly-comma option
-@cindex options, -fugly-comma
-@item -fugly-comma
-In an external-procedure invocation,
-treat a trailing comma in the argument list
-as specification of a trailing null argument,
-and treat an empty argument list
-as specification of a single null argument.
-
-For example, @samp{CALL FOO(,)} is treated as
-@samp{CALL FOO(%VAL(0), %VAL(0))}.
-That is, @emph{two} null arguments are specified
-by the procedure call when @option{-fugly-comma} is in force.
-And @samp{F = FUNC()} is treated as @samp{F = FUNC(%VAL(0))}.
-
-The default behavior, @option{-fno-ugly-comma}, is to ignore
-a single trailing comma in an argument list.
-So, by default, @samp{CALL FOO(X,)} is treated
-exactly the same as @samp{CALL FOO(X)}.

-Disallow use of Hollerith and typeless constants as initial
-values (in @code{PARAMETER} and @code{DATA} statements), and

-initialize numeric types and vice versa.
-
-For example, @samp{DATA I/'F'/, CHRVAR/65/, J/4HABCD/} is disallowed by

-@cindex one-trip @code{DO} loops
-@cindex @code{DO} loops, zero-trip
-@cindex zero-trip @code{DO} loops
-@cindex compatibility, FORTRAN 66
-Executable iterative @code{DO} loops are to be executed at
-least once each time they are reached.
-
-ANSI FORTRAN 77 and more recent versions of the Fortran standard
-specify that the body of an iterative @code{DO} loop is not executed
-if the number of iterations calculated from the parameters of the
-loop is less than 1.
-(For example, @samp{DO 10 I = 1, 0}.)
-Such a loop is called a @dfn{zero-trip loop}.
-
-Prior to ANSI FORTRAN 77, many compilers implemented @code{DO} loops
-such that the body of a loop would be executed at least once, even
-if the iteration count was zero.
-Fortran code written assuming this behavior is said to require
-@dfn{one-trip loops}.
-For example, some code written to the FORTRAN 66 standard
-expects this behavior from its @code{DO} loops, although that
-standard did not specify this behavior.
-
-The @option{-fonetrip} option specifies that the source file(s) being
-compiled require one-trip loops.
-
-This option affects only those loops specified by the (iterative) @code{DO}
-statement and by implied-@code{DO} lists in I/O statements.
-Loops specified by implied-@code{DO} lists in @code{DATA} and
-specification (non-executable) statements are not affected.

-@section Options to Request or Suppress Warnings
-@cindex options, warnings
-@cindex warnings, suppressing
-@cindex messages, warning
-@cindex suppressing warnings
-
-Warnings are diagnostic messages that report constructions which
-are not inherently erroneous but which are risky or suggest there
-might have been an error.
-
-You can request many specific warnings with options beginning @option{-W},
-for example @option{-Wimplicit} to request warnings on implicit
-declarations. Each of these specific warning options also has a
-negative form beginning @option{-Wno-} to turn off warnings;
-for example, @option{-Wno-implicit}. This manual lists only one of the
-two forms, whichever is not the default.
-
-These options control the amount and kinds of warnings produced by GNU
-Fortran:
-
-@table @gcctabopt
-@cindex syntax checking
-@cindex -fsyntax-only option
-@cindex options, -fsyntax-only
-@item -fsyntax-only
-Check the code for syntax errors, but don't do anything beyond that.
-
-@cindex -pedantic option
-@cindex options, -pedantic
-@item -pedantic
-Issue warnings for uses of extensions to ANSI FORTRAN 77.
-@option{-pedantic} also applies to C-language constructs where they
-occur in GNU Fortran source files, such as use of @samp{\e} in a
-character constant within a directive like @samp{#include}.
-
-Valid ANSI FORTRAN 77 programs should compile properly with or without
-this option.
-However, without this option, certain GNU extensions and traditional
-Fortran features are supported as well.
-With this option, many of them are rejected.
-
-Some users try to use @option{-pedantic} to check programs for strict ANSI
-conformance.
-They soon find that it does not do quite what they want---it finds some
-non-ANSI practices, but not all.
-However, improvements to @command{g77} in this area are welcome.
-
-@cindex -pedantic-errors option
-@cindex options, -pedantic-errors
-@item -pedantic-errors
-Like @option{-pedantic}, except that errors are produced rather than
-warnings.
-
-@cindex -fpedantic option
-@cindex options, -fpedantic
-@item -fpedantic
-Like @option{-pedantic}, but applies only to Fortran constructs.
-
-@cindex -w option
-@cindex options, -w
-@item -w
-Inhibit all warning messages.
-
-@cindex -Wno-globals option
-@cindex options, -Wno-globals
-@item -Wno-globals
-@cindex global names, warning
-@cindex warnings, global names
-Inhibit warnings about use of a name as both a global name
-(a subroutine, function, or block data program unit, or a
-common block) and implicitly as the name of an intrinsic
-in a source file.
-
-Also inhibit warnings about inconsistent invocations and/or
-definitions of global procedures (function and subroutines).
-Such inconsistencies include different numbers of arguments
-and different types of arguments.
-
-@cindex -Wimplicit option
-@cindex options, -Wimplicit
-@item -Wimplicit
-@cindex implicit declaration, warning
-@cindex warnings, implicit declaration
-@cindex -u option
-@cindex /WARNINGS=DECLARATIONS switch
-@cindex IMPLICIT NONE, similar effect
-@cindex effecting IMPLICIT NONE
-Warn whenever a variable, array, or function is implicitly
-declared.
-Has an effect similar to using the @code{IMPLICIT NONE} statement
-in every program unit.
-(Some Fortran compilers provide this feature by an option
-named @option{-u} or @samp{/WARNINGS=DECLARATIONS}.)
-
-@cindex -Wunused option
-@cindex options, -Wunused
-@item -Wunused
-@cindex unused variables
-@cindex variables, unused
-Warn whenever a variable is unused aside from its declaration.
-
-@cindex -Wuninitialized option
-@cindex options, -Wuninitialized
-@item -Wuninitialized
-@cindex uninitialized variables
-@cindex variables, uninitialized
-Warn whenever an automatic variable is used without first being initialized.
-
-These warnings are possible only in optimizing compilation,
-because they require data-flow information that is computed only
-when optimizing. If you don't specify @option{-O}, you simply won't
-get these warnings.
-
-These warnings occur only for variables that are candidates for
-register allocation. Therefore, they do not occur for a variable
-@c that is declared @code{VOLATILE}, or
-whose address is taken, or whose size
-is other than 1, 2, 4 or 8 bytes. Also, they do not occur for
-arrays, even when they are in registers.
-
-Note that there might be no warning about a variable that is used only
-to compute a value that itself is never used, because such
-computations may be deleted by data-flow analysis before the warnings
-are printed.
-
-These warnings are made optional because GNU Fortran is not smart
-enough to see all the reasons why the code might be correct
-despite appearing to have an error. Here is one example of how
-this can happen:
-
-@example
-SUBROUTINE DISPAT(J)
-IF (J.EQ.1) I=1
-IF (J.EQ.2) I=4
-IF (J.EQ.3) I=5
-CALL FOO(I)
-END
-@end example
-
-@noindent
-If the value of @code{J} is always 1, 2 or 3, then @code{I} is
-always initialized, but GNU Fortran doesn't know this. Here is
-another common case:
-
-@example
-SUBROUTINE MAYBE(FLAG)
-LOGICAL FLAG
-IF (FLAG) VALUE = 9.4
-@dots{}
-IF (FLAG) PRINT *, VALUE
-END
-@end example
-
-@noindent
-This has no bug because @code{VALUE} is used only if it is set.
-
-@cindex -Wall option
-@cindex options, -Wall
-@item -Wall
-@cindex all warnings
-@cindex warnings, all
-The @option{-Wunused} and @option{-Wuninitialized} options combined.

-(As more warnings are added to @command{g77} some might
-be added to the list enabled by @option{-Wall}.)
-@end table
-
-The remaining @option{-W@dots{}} options are not implied by @option{-Wall}
-because they warn about constructions that we consider reasonable to
-use, on occasion, in clean programs.
-

-@c @item -W

-@c @end itemize
-@c
-@cindex -Wsurprising option
-@cindex options, -Wsurprising
-@item -Wsurprising
-Warn about ``suspicious'' constructs that are interpreted
-by the compiler in a way that might well be surprising to
-someone reading the code.
-These differences can result in subtle, compiler-dependent
-(even machine-dependent) behavioral differences.
-The constructs warned about include:
-
-@itemize @bullet
-@item
-Expressions having two arithmetic operators in a row, such
-as @samp{X*-Y}.
-Such a construct is nonstandard, and can produce
-unexpected results in more complicated situations such
-as @samp{X**-Y*Z}.
-@command{g77} along with many other compilers, interprets
-this example differently than many programmers, and a few
-other compilers.
-Specifically, @command{g77} interprets @samp{X**-Y*Z} as
-@samp{(X**(-Y))*Z}, while others might think it should
-be interpreted as @samp{X**(-(Y*Z))}.
-
-A revealing example is the constant expression @samp{2**-2*1.},
-which @command{g77} evaluates to .25, while others might evaluate
-it to 0., the difference resulting from the way precedence affects
-type promotion.
-
-(The @option{-fpedantic} option also warns about expressions
-having two arithmetic operators in a row.)
-
-@item
-Expressions with a unary minus followed by an operand and then
-a binary operator other than plus or minus.
-For example, @samp{-2**2} produces a warning, because
-the precedence is @samp{-(2**2)}, yielding -4, not
-@samp{(-2)**2}, which yields 4, and which might represent
-what a programmer expects.
-
-An example of an expression producing different results
-in a surprising way is @samp{-I*S}, where @var{I} holds
-the value @samp{-2147483648} and @var{S} holds @samp{0.5}.
-On many systems, negating @var{I} results in the same
-value, not a positive number, because it is already the
-lower bound of what an @code{INTEGER(KIND=1)} variable can hold.
-So, the expression evaluates to a positive number, while
-the ``expected'' interpretation, @samp{(-I)*S}, would
-evaluate to a negative number.
-
-Even cases such as @samp{-I*J} produce warnings,
-even though, in most configurations and situations,
-there is no computational difference between the
-results of the two interpretations---the purpose
-of this warning is to warn about differing interpretations
-and encourage a better style of coding, not to identify
-only those places where bugs might exist in the user's
-code.
-
-@cindex DO statement
-@cindex statements, DO
-@item
-@code{DO} loops with @code{DO} variables that are not
-of integral type---that is, using @code{REAL}
-variables as loop control variables.
-Although such loops can be written to work in the
-``obvious'' way, the way @command{g77} is required by the
-Fortran standard to interpret such code is likely to
-be quite different from the way many programmers expect.
-(This is true of all @code{DO} loops, but the differences

-Might help a Fortran program that depends on exact IEEE conformance on

-
-This option is effective when the floating-point unit is set to work in
-IEEE 854 `extended precision'---as it typically is on x86 and m68k GNU
-systems---rather than IEEE 754 double precision. @option{-ffloat-store}
-tries to remove the extra precision by spilling data from floating-point
-registers into memory and this typically involves a big performance
-hit. However, it doesn't affect intermediate results, so that it is
-only partially effective. `Excess precision' is avoided in code like:
-@smallexample
-a = b + c
-d = a * e
-@end smallexample
-but not in code like:
-@smallexample
- d = (b + c) * e
-@end smallexample

-@c CB: I've decided on `iterative', for the time being, and changed
-@c my previous, rather bizarre, use of `imperative' to that
-@c (though `precomputed-trip' would be a more precise adjective)
-Typically improves performance on code using iterative @code{DO} loops by
-unrolling them and is probably generally appropriate for Fortran, though
-it is not turned on at any optimization level.
-Note that outer loop unrolling isn't done specifically; decisions about
-whether to unroll a loop are made on the basis of its instruction count.
-
-@c DL: Fixme: This should obviously go somewhere else...
-Also, no `loop discovery'@footnote{@dfn{loop discovery} refers to the
-process by which a compiler, or indeed any reader of a program,
-determines which portions of the program are more likely to be executed
-repeatedly as it is being run. Such discovery typically is done early
-when compiling using optimization techniques, so the ``discovered''
-loops get more attention---and more run-time resources, such as
-registers---from the compiler. It is easy to ``discover'' loops that are
-constructed out of looping constructs in the language
-(such as Fortran's @code{DO}). For some programs, ``discovering'' loops
-constructed out of lower-level constructs (such as @code{IF} and
-@code{GOTO}) can lead to generation of more optimal code
-than otherwise.} is done, so only loops written with @code{DO}
-benefit from loop optimizations, including---but not limited
-to---unrolling. Loops written with @code{IF} and @code{GOTO} are not
-currently recognized as such. This option unrolls only iterative

-@c DL: Check my understanding of -funroll-all-loops v. -funroll-loops is correct.
-Probably improves performance on code using @code{DO WHILE} loops by

-
-@option{-fmove-all-movables} and @option{-freduce-all-givs} will enable

-
-Since there is a run-time penalty for initialization of variables
-that are not given the @code{SAVE} attribute, it might be a

-

-@cindex options, -fno-f2c

-@cindex @command{f2c} compatibility
-@cindex compatibility, @command{f2c}
-Do not generate code designed to be compatible with code generated
-by @command{f2c} use the GNU calling conventions instead.
-
-The @command{f2c} calling conventions require functions that return
-type @code{REAL(KIND=1)} to actually return the C type @code{double},
-and functions that return type @code{COMPLEX} to return the
-values via an extra argument in the calling sequence that points
-to where to store the return value.
-Under the GNU calling conventions, such functions simply return
-their results as they would in GNU C---@code{REAL(KIND=1)} functions
-return the C type @code{float}, and @code{COMPLEX} functions
-return the GNU C type @code{complex} (or its @code{struct}
-equivalent).
-
-This does not affect the generation of code that interfaces with the
-@code{libg2c} library.
-
-However, because the @code{libg2c} library uses @command{f2c}
-calling conventions, @command{g77} rejects attempts to pass
-intrinsics implemented by routines in this library as actual
-arguments when @option{-fno-f2c} is used, to avoid bugs when
-they are actually called by code expecting the GNU calling
-conventions to work.
-
-For example, @samp{INTRINSIC ABS;CALL FOO(ABS)} is
-rejected when @option{-fno-f2c} is in force.
-(Future versions of the @command{g77} run-time library might
-offer routines that provide GNU-callable versions of the
-routines that implement the @command{f2c} intrinsics
-that may be passed as actual arguments, so that
-valid programs need not be rejected when @option{-fno-f2c}
-is used.)
-
-@strong{Caution:} If @option{-fno-f2c} is used when compiling any
-source file used in a program, it must be used when compiling
-@emph{all} Fortran source files used in that program.
-
-@c seems kinda dumb to tell people about an option they can't use -- jcb

-is required.
-This is the default for the current version of @command{g77}
-
-Currently it is not
-valid to specify @option{-fno-f2c-library}.
-This option is provided so users can specify it in shell
-scripts that build programs and libraries that require the

-@cindex underscore
-@cindex symbol names, underscores
-@cindex transforming symbol names
-@cindex symbol names, transforming
-Do not transform names of entities specified in the Fortran
-source file by appending underscores to them.
-
-With @option{-funderscoring} in effect, @command{g77} appends two underscores
-to names with underscores and one underscore to external names with
-no underscores. (@command{g77} also appends two underscores to internal
-names with underscores to avoid naming collisions with external names.
-The @option{-fno-second-underscore} option disables appending of the
-second underscore in all cases.)
-
-This is done to ensure compatibility with code produced by many
-UNIX Fortran compilers, including @command{f2c} which perform the
-same transformations.
-
-Use of @option{-fno-underscoring} is not recommended unless you are
-experimenting with issues such as integration of (GNU) Fortran into
-existing system environments (vis-a-vis existing libraries, tools, and
-so on).
-
-For example, with @option{-funderscoring}, and assuming other defaults like
-@option{-fcase-lower} and that @samp{j()} and @samp{max_count()} are
-external functions while @samp{my_var} and @samp{lvar} are local variables,
-a statement like
-
-@smallexample
-I = J() + MAX_COUNT (MY_VAR, LVAR)
-@end smallexample
-
-@noindent
-is implemented as something akin to:
-
-@smallexample
-i = j_() + max_count__(&my_var__, &lvar);
-@end smallexample
-
-With @option{-fno-underscoring}, the same statement is implemented as:
-
-@smallexample
-i = j() + max_count(&my_var, &lvar);
-@end smallexample
-
-Use of @option{-fno-underscoring} allows direct specification of
-user-defined names while debugging and when interfacing @command{g77}
-code with other languages.
-
-Note that just because the names match does @emph{not} mean that the
-interface implemented by @command{g77} for an external name matches the
-interface implemented by some other language for that same name.
-That is, getting code produced by @command{g77} to link to code produced
-by some other compiler using this or any other method can be only a
-small part of the overall solution---getting the code generated by
-both compilers to agree on issues other than naming can require
-significant effort, and, unlike naming disagreements, linkers normally
-cannot detect disagreements in these other areas.
-
-Also, note that with @option{-fno-underscoring}, the lack of appended
-underscores introduces the very real possibility that a user-defined
-external name will conflict with a name in a system library, which
-could make finding unresolved-reference bugs quite difficult in some
-cases---they might occur at program run time, and show up only as
-buggy behavior at run time.
-
-In future versions of @command{g77} we hope to improve naming and linking
-issues so that debugging always involves using the names as they appear
-in the source, even if the names as seen by the linker are mangled to
-prevent accidental linking between procedures with incompatible
-interfaces.

-
-This option has no effect if @option{-fno-underscoring} is
-in effect.
-
-Otherwise, with this option, an external name such as @samp{MAX_COUNT}
-is implemented as a reference to the link-time external symbol
-@samp{max_count_}, instead of @samp{max_count__}.

-Ignore the @samp{#ident} directive.
-
-@cindex -fzeros option
-@cindex options, -fzeros
-@item -fzeros
-Treat initial values of zero as if they were any other value.
-
-As of version 0.5.18, @command{g77} normally treats @code{DATA} and
-other statements that are used to specify initial values of zero
-for variables and arrays as if no values were actually specified,
-in the sense that no diagnostics regarding multiple initializations
-are produced.
-
-This is done to speed up compiling of programs that initialize
-large arrays to zeros.
-
-Use @option{-fzeros} to revert to the simpler, slower behavior
-that can catch multiple initializations by keeping track of
-all initializations, zero or otherwise.
-
-@emph{Caution:} Future versions of @command{g77} might disregard this option
-(and its negative form, the default) or interpret it somewhat
-differently.
-The interpretation changes will affect only non-standard
-programs; standard-conforming programs should not be affected.

-
-(@command{gcc} had some bugs in its back-end support
-for @code{complex} arithmetic, due primarily to the support not being
-completed as of version 2.8.1 and @code{egcs} 1.1.2.)
-
-Use @option{-femulate-complex} if you suspect code-generation bugs,
-or experience compiler crashes,
-that might result from @command{g77} using the @code{COMPLEX} support
-in the @command{gcc} back end.
-If using that option fixes the bugs or crashes you are seeing,
-that indicates a likely @command{g77} bugs
-(though, all compiler crashes are considered bugs),
-so, please report it.
-(Note that the known bugs, now believed fixed, produced compiler crashes
-rather than causing the generation of incorrect code.)
-
-Use of this option should not affect how Fortran code compiled
-by @command{g77} works in terms of its interfaces to other code,
-e.g. that compiled by @command{f2c}
-
-As of GCC version 3.0, this option is not necessary anymore.

-(The diagnostics themselves are still produced, but

-in which case no relevant diagnostics are produced.)
-
-Further, this option disables such inlining, to
-avoid compiler crashes resulting from incorrect
-code that would otherwise be diagnosed.
-
-As such, this option might be quite useful when
-compiling existing, ``working'' code that happens
-to have a few bugs that do not generally show themselves,
-but which @command{g77} diagnoses.
-
-Use of this option therefore has the effect of
-instructing @command{g77} to behave more like it did
-up through version 0.5.19.1, when it paid little or
-no attention to disagreements between program units
-about a procedure's type and argument information,
-and when it performed no inlining of procedures
-(except statement functions).
-
-Without this option, @command{g77} defaults to performing
-the potentially inlining procedures as it started doing
-in version 0.5.20, but as of version 0.5.21, it also
-diagnoses disagreements that might cause such inlining
-to crash the compiler as (fatal) errors,

-@command{g77} generates a single check per @emph{subscript} expression.
-This catches some cases of potential bugs that @command{f2c} does not,
-such as references to below the beginning of an assumed-size array.
-
-@command{g77} also generates checks for @code{CHARACTER} substring references,
-something @command{f2c} currently does not do.
-
-Use the new @option{-ffortran-bounds-check} option
-to specify bounds-checking for only the Fortran code you are compiling,
-not necessarily for code written in other languages.
-
-@emph{Note:} To provide more detailed information on the offending subscript,
-@command{g77} provides the @code{libg2c} run-time library routine @code{s_rnge}
-with somewhat differently-formatted information.
-Here's a sample diagnostic:
-
-@smallexample
-Subscript out of range on file line 4, procedure rnge.f/bf.
-Attempt to access the -6-th element of variable b[subscript-2-of-2].
-Aborted
-@end smallexample
-
-The above message indicates that the offending source line is
-line 4 of the file @file{rnge.f},
-within the program unit (or statement function) named @samp{bf}.
-The offended array is named @samp{b}.
-The offended array dimension is the second for a two-dimensional array,
-and the offending, computed subscript expression was @samp{-6}.
-
-For a @code{CHARACTER} substring reference, the second line has
-this appearance:
-
-@smallexample
-Attempt to access the 11-th element of variable a[start-substring].
-@end smallexample
-
-This indicates that the offended @code{CHARACTER} variable or array
-is named @samp{a},
-the offended substring position is the starting (leftmost) position,
-and the offending substring expression is @samp{11}.
-
-(Though the verbage of @code{s_rnge} is not ideal
-for the purpose of the @command{g77} compiler,
-the above information should provide adequate diagnostic abilities
-to it users.)
-@end table
-
-@xref{Code Gen Options,,Options for Code Generation Conventions,
-gcc,Using the GNU Compiler Collection (GCC)}, for information on more options
-offered by the GBE
-shared by @command{g77} @command{gcc} and other GNU compilers.
-
-Some of these do @emph{not} work when compiling programs written in Fortran:
-
-@table @gcctabopt
-@cindex -fpcc-struct-return option
-@cindex options, -fpcc-struct-return
-@item -fpcc-struct-return
-@cindex -freg-struct-return option
-@cindex options, -freg-struct-return
-@item -freg-struct-return
-You should not use these except strictly the same way as you
-used them to build the version of @code{libg2c} with which
-you will be linking all code compiled by @command{g77} with the
-same option.
-
-@cindex -fshort-double option
-@cindex options, -fshort-double
-@item -fshort-double
-This probably either has no effect on Fortran programs, or
-makes them act loopy.
-
-@cindex -fno-common option
-@cindex options, -fno-common
-@item -fno-common
-Do not use this when compiling Fortran programs,
-or there will be Trouble.
-
-@cindex -fpack-struct option
-@cindex options, -fpack-struct
-@item -fpack-struct
-This probably will break any calls to the @code{libg2c} library,
-at the very least, even if it is built with the same option.

- label) aside from a positive continuation character might have meaning
- in the midst of a character or hollerith constant.
-
- 2. If a line has no explicit continuation character (that is, it has a

- not a digit 0-9), then there are two possibilities:
-
- A. A label is present and/or a non-space (and non-comment) character
- appears somewhere after column 6. Terminate processing of the previous
- statement, if any, send the new label for the next statement, if any,
- and start processing a new statement with this non-blank character, if
- any.
-
- B. The line is essentially blank, except for a possible comment character.
- Don't terminate processing of the previous statement and don't pass any
- characters to the parser tasks, since the line is not flagged as a
- continuation line. We treat it just like a completely blank line.
-
- 3. If a line has a continuation character of zero (0), then we terminate
- processing of the previous statement, if any, send the new label for the
- next statement, if any, and start processing a new statement, if any
- non-blank characters are present.
-
- If, when checking to see if we should terminate the previous statement, it

- Like ffelex_set_names, except affects both lexers. Normally, the
- free-form lexer need not generate NAMES tokens because adjacent NAME
- tokens must be separated by spaces which causes the lexer to generate
- separate tokens for analysis (whereas in fixed-form the spaces are
- ignored resulting in one long token). But in FORMAT statements, for
- some reason, the Fortran 90 standard specifies that spaces can occur
- anywhere within a format-item-list with no effect on the format spec
- (except of course within character string edit descriptors), which means
- that "1PE14.2" and "1 P E 1 4 . 2" are equivalent. For the FORMAT
- statement handling, the existence of spaces makes it hard to deal with,
- because each token is seen distinctly (i.e. seven tokens in the latter
- example). But when no spaces are provided, as in the former example,
- then only four tokens are generated, NUMBER("1"), NAME("PE14"), PERIOD,
- NUMBER ("2"). By generating a NAMES instead of NAME, three things happen:
- One, ffest_kw_format_ does a substring rather than full-string match,
- and thus matches "PE14" to "PE"; two, ffelex_token_xyz_from_names functions
- may be used to pull NAME/NAMES and NUMBER tokens out of the NAMES token;
- and three, error reporting can point to the actual character rather than
- at or prior to it. The first two things could be resolved by providing
- alternate functions fairly easy, thus allowing FORMAT handling to expect
- both lexers to generate NAME tokens instead of NAMES (with otherwise minor
- changes to FORMAT parsing), but the third, error reporting, would suffer,
- and when one makes mistakes in a FORMAT, believe me, one wants a pointer
- to exactly where the compilers thinks the problem is, to even begin to get
- a handle on it. So there. */

-code they compile with @command{g77}.
-Information on changes to installation procedures,
-changes to the documentation, and bug fixes is

-Changes made to recent versions of GNU Fortran are listed
-below, with the most recent version first.
-
-The changes are generally listed in order:
-
-@enumerate
-@item
-Code-generation and run-time-library bug-fixes
-
-@item
-Compiler and run-time-library crashes involving valid code
-that have been fixed
-
-@item
-New features
-
-@item
-Fixes and enhancements to existing features
-
-@item
-New diagnostics
-
-@item
-Internal improvements
-
-@item
-Miscellany
-@end enumerate
-
-This order is not strict---for example, some items
-involve a combination of these elements.
-@end ifclear
-
-Note that two variants of @command{g77} are tracked below.
-The @code{egcs} variant is described vis-a-vis
-previous versions of @code{egcs} and/or
-an official FSF version, as appropriate.
-Note that all such variants are obsolete @emph{as of July 1999} -
-the information is retained here only for its historical value.
-
-Therefore, @code{egcs} versions sometimes have multiple listings
-to help clarify how they differ from other versions,
-though this can make getting a complete picture
-of what a particular @code{egcs} version contains
-somewhat more difficult.
-
-@ifset DOC-G77
-For information on bugs in the @value{which-g77} version of @command{g77},
-see @ref{Known Bugs,,Known Bugs In GNU Fortran}.

-
-@ifset DEVELOPMENT
-@emph{Warning:} The information below is still under development,
-and might not accurately reflect the @command{g77} code base
-of which it is a part.
-Efforts are made to keep it somewhat up-to-date,
-but they are particularly concentrated
-on any version of this information
-that is distributed as part of a @emph{released} @command{g77}.
-
-In particular, while this information is intended to apply to
-the @value{which-g77} version of @command{g77},
-only an official @emph{release} of that version
-is expected to contain documentation that is
-most consistent with the @command{g77} product in that version.
-
-Nevertheless, information on @emph{previous} releases of @command{g77}, below,
-is likely to be more up-to-date and accurate
-than the equivalent information that accompanied
-those releases,
-assuming the last-updated date of the information below
-is later than the dates of those releases.
-
-That's due to attempts to keep this development version
-of news about previous @command{g77} versions up-to-date.
-@end ifset

-An online, ``live'' version of this document
-(derived directly from the mainline, development version

-@heading In 0.5.23 versus 0.5.22:
-@itemize @bullet
-@item
-This release contains several regressions against
-version 0.5.22 of @command{g77}, due to using the
-``vanilla'' @command{gcc} back end instead of patching
-it to fix a few bugs and improve performance in a
-few cases.
-
-Features that have been dropped from this version
-of @command{g77} due to their being implemented
-via @command{g77}-specific patches to the @command{gcc}
-back end in previous releases include:
-
-@itemize @minus
-@item
-Support for @code{__restrict__} keyword,
-the options @option{-fargument-alias}, @option{-fargument-noalias},
-and @option{-fargument-noalias-global},
-and the corresponding alias-analysis code.
-
-(@code{egcs} has the alias-analysis
-code, but not the @code{__restrict__} keyword.
-@code{egcs} @command{g77} users benefit from the alias-analysis
-code despite the lack of the @code{__restrict__} keyword,
-which is a C-language construct.)
-
-@item
-Support for the GNU compiler options
-@option{-fmove-all-movables},
-@option{-freduce-all-givs},
-and @option{-frerun-loop-opt}.
-
-(@code{egcs} supports these options.
-@command{g77} users of @code{egcs} benefit from them even if
-they are not explicitly specified,
-because the defaults are optimized for @command{g77} users.)

-@c @command{g77}'s version of @code{libf2c} has been modified
-@c so that the external names of library's procedures do not
-@c conflict with names used for Fortran procedures compiled
-@c by @command{g77}.
-@c An additional layer of jacket procedures has been added
-@c to @code{libf2c} to map the old names to the new names,
-@c for automatic use by programs that interface to the
-@c library procedures via the external-procedure mechanism.
-@c
-@c For example, the intrinsic @code{FPUTC} previously was
-@c implemented by @command{g77} as a call to the @code{libf2c}
-@c routine @code{fputc_}.
-@c This would conflict with a Fortran procedure named @code{FPUTC}
-@c (using default compiler options), and this conflict
-@c would cause a crash under certain circumstances.
-@c
-@c Now, the intrinsic @code{FPUTC} calls @code{G77_fputc_0},
-@c which does not conflict with the @code{fputc_} external
-@c that implements a Fortran procedure named @code{FPUTC}.
-@c
-@c Programs that refer to @code{FPUTC} as an external procedure
-@c without supplying their own implementation will link to
-@c the new @code{libf2c} routine @code{fputc_}, which is
-@c simply a jacket routine that calls @code{G77_fputc_0}.

-to perform some of what @option{-fugly} used to do.
-@option{-fugly} and @option{-fno-ugly} are now ``shorthand'' options,
-in that they do nothing more than enable (or disable) other
-@option{-fugly-*} options.
-
-@item
-Fix parsing of assignment statements involving targets that
-are substrings of elements of @code{CHARACTER} arrays having
-names such as @samp{READ}, @samp{WRITE}, @samp{GOTO}, and
-@samp{REALFUNCTIONFOO}.
-
-@item
-Fix crashes involving diagnosed code.
-
-@item
-Fix handling of local @code{EQUIVALENCE} areas so certain cases
-of valid Fortran programs are not misdiagnosed as improperly
-extending the area backwards.
-
-@item
-Support @command{gcc} version 2.7.2.1.
-
-@item
-Upgrade to @code{libf2c} as of 1996-09-26, and
-fix up some of the build procedures.
-
-@item
-Change code generation for list-directed I/O so it allows
-for new versions of @code{libf2c} that might return nonzero
-status codes for some operations previously assumed to always
-return zero.
-
-This change not only affects how @code{IOSTAT=} variables
-are set by list-directed I/O, it also affects whether
-@code{END=} and @code{ERR=} labels are reached by these
-operations.
-
-@item
-Add intrinsic support for new @code{FTELL} and @code{FSEEK}
-procedures in @code{libf2c}.
-
-@item
-Modify @code{fseek_()} in @code{libf2c} to be more portable
-(though, in practice, there might be no systems where this
-matters) and to catch invalid @code{whence} arguments.
-
-@item
-Some useless warnings from the @option{-Wunused} option have
-been eliminated.
-
-@item
-Fix a problem building the @file{f771} executable
-on AIX systems by linking with the @option{-bbigtoc} option.
-
-@item
-Abort configuration if @command{gcc} has not been patched
-using the patch file provided in the @file{gcc/f/gbe/}
-subdirectory.
-
-@item
-Add options @option{--help} and @option{--version} to the
-@command{g77} command, to conform to GNU coding guidelines.
-Also add printing of @command{g77} version number when
-the @option{--verbose} (@option{-v}) option is used.
-
-@item
-Change internally generated name for local @code{EQUIVALENCE}
-areas to one based on the alphabetically sorted first name
-in the list of names for entities placed at the beginning
-of the areas.
-

-Improvements to documentation and indexing.
-@end itemize
-
-@c 1996-04-01: 0.5.18 released.
-@heading In 0.5.18:
-@itemize @bullet
-@item
-Add some rudimentary support for @code{INTEGER*1},
-@code{INTEGER*2}, @code{INTEGER*8},
-and their @code{LOGICAL} equivalents.
-(This support works on most, maybe all, @command{gcc} targets.)
-
-Thanks to Scott Snyder (@email{snyder@@d0sgif.fnal.gov})
-for providing the patch for this!
-
-Among the missing elements from the support for these
-features are full intrinsic support and constants.
-
-@item
-Add some rudimentary support for the @code{BYTE} and
-@code{WORD} type-declaration statements.
-@code{BYTE} corresponds to @code{INTEGER*1},
-while @code{WORD} corresponds to @code{INTEGER*2}.
-
-Thanks to Scott Snyder (@email{snyder@@d0sgif.fnal.gov})
-for providing the patch for this!
-
-@item
-The compiler code handling intrinsics has been largely
-rewritten to accommodate the new types.
-No new intrinsics or arguments for existing
-intrinsics have been added, so there is, at this
-point, no intrinsic to convert to @code{INTEGER*8},
-for example.
-
-@item
-Support automatic arrays in procedures.
-
-@item
-Reduce space/time requirements for handling large
-@emph{sparsely} initialized aggregate arrays.
-This improvement applies to only a subset of
-the general problem to be addressed in 0.6.
-
-@item
-Treat initial values of zero as if they weren't
-specified (in DATA and type-declaration statements).
-The initial values will be set to zero anyway, but the amount
-of compile time processing them will be reduced,
-in some cases significantly (though, again, this
-is only a subset of the general problem to be
-addressed in 0.6).
-
-A new option, @option{-fzeros}, is introduced to
-enable the traditional treatment of zeros as any
-other value.
-
-@item
-With @option{-ff90} in force, @command{g77} incorrectly
-interpreted @samp{REAL(Z)} as returning a @code{REAL}
-result, instead of as a @code{DOUBLE PRECISION}
-result.
-(Here, @samp{Z} is @code{DOUBLE COMPLEX}.)
-
-With @option{-fno-f90} in force, the interpretation remains
-unchanged, since this appears to be how at least some
-F77 code using the @code{DOUBLE COMPLEX} extension expected
-it to work.
-
-Essentially, @samp{REAL(Z)} in F90 is the same as
-@samp{DBLE(Z)}, while in extended F77, it appears to
-be the same as @samp{REAL(REAL(Z))}.
-
-@item
-An expression involving exponentiation, where both operands
-were type @code{INTEGER} and the right-hand operand
-was negative, was erroneously evaluated.
-
-@item
-Fix bugs involving @code{DATA} implied-@code{DO} constructs
-(these involved an errant diagnostic and a crash, both on good
-code, one involving subsequent statement-function definition).
-
-@item
-Close @code{INCLUDE} files after processing them, so compiling source
-files with lots of @code{INCLUDE} statements does not result in
-being unable to open @code{INCLUDE} files after all the available
-file descriptors are used up.
-
-@item
-Speed up compiling, especially of larger programs, and perhaps
-slightly reduce memory utilization while compiling (this is
-@emph{not} the improvement planned for 0.6 involving large aggregate
-areas)---these improvements result from simply turning
-off some low-level code to do self-checking that hasn't been
-triggered in a long time.
-
-@item
-Introduce three new options that
-implement optimizations in the @command{gcc} back end (GBE).
-These options are @option{-fmove-all-movables}, @option{-freduce-all-givs},
-and @option{-frerun-loop-opt}, which are enabled, by default,
-for Fortran compilations.
-These optimizations are intended to help toon Fortran programs.
-
-@item
-Patch the GBE to do a better job optimizing certain
-kinds of references to array elements.
-
-@item
-Due to patches to the GBE, the version number of @command{gcc}
-also is patched to make it easier to manage installations,
-especially useful if it turns out a @command{g77} change to the
-GBE has a bug.
-
-The @command{g77}-modified version number is the @command{gcc}
-version number with the string @samp{.f.@var{n}} appended,
-where @samp{f} identifies the version as enhanced for
-Fortran, and @var{n} is @samp{1} for the first Fortran
-patch for that version of @command{gcc}, @samp{2} for the
-second, and so on.
-
-So, this introduces version 2.7.2.f.1 of @command{gcc}.
-
-@item
-Make several improvements and fixes to diagnostics, including
-the removal of two that were inappropriate or inadequate.
-
-@item
-Warning about two successive arithmetic operators, produced
-by @option{-Wsurprising}, now produced @emph{only} when both
-operators are, indeed, arithmetic (not relational/boolean).
-
-@item
-@option{-Wsurprising} now warns about the remaining cases
-of using non-integral variables for implied-@code{DO}
-loops, instead of these being rejected unless @option{-fpedantic}
-or @option{-fugly} specified.
-
-@item
-Allow @code{SAVE} of a local variable or array, even after
-it has been given an initial value via @code{DATA}, for example.
-
-@item
-Introduce an Info version of @command{g77} documentation, which
-supersedes @file{gcc/f/CREDITS}, @file{gcc/f/DOC}, and
-@file{gcc/f/PROJECTS}.
-These files will be removed in a future release.
-The files @file{gcc/f/BUGS}, @file{gcc/f/INSTALL}, and
-@file{gcc/f/NEWS} now are automatically built from
-the texinfo source when distributions are made.
-
-This effort was inspired by a first pass at translating
-@file{g77-0.5.16/f/DOC} that was contributed to Craig by
-David Ronis (@email{ronis@@onsager.chem.mcgill.ca}).
-
-@item
-New @option{-fno-second-underscore} option to specify
-that, when @option{-funderscoring} is in effect, a second
-underscore is not to be appended to Fortran names already
-containing an underscore.
-
-@item
-Change the way iterative @code{DO} loops work to follow
-the F90 standard.
-In particular, calculation of the iteration count is
-still done by converting the start, end, and increment
-parameters to the type of the @code{DO} variable, but
-the result of the calculation is always converted to
-the default @code{INTEGER} type.
-
-(This should have no effect on existing code compiled
-by @command{g77}, but code written to assume that use
-of a @emph{wider} type for the @code{DO} variable
-will result in an iteration count being fully calculated
-using that wider type (wider
-than default @code{INTEGER}) must be rewritten.)
-
-@item
-Support @command{gcc} version 2.7.2.
-
-@item
-Upgrade to @code{libf2c} as of 1996-03-23, and
-fix up some of the build procedures.
-
-Note that the email addresses related to @command{f2c}
-have changed---the distribution site now is
-named @code{netlib.bell-labs.com}, and the
-maintainer's new address is @email{dmg@@bell-labs.com}.

-@c 1995-11-18: 0.5.17 released.
-@heading In 0.5.17:
-@itemize @bullet
-@item
-@strong{Fix serious bug} in @samp{g77 -v} command that can cause removal of a
-system's @file{/dev/null} special file if run by user @code{root}.
-
-@strong{All users} of version 0.5.16 should ensure that
-they have not removed @file{/dev/null} or replaced it with an ordinary
-file (e.g. by comparing the output of @samp{ls -l /dev/null} with
-@samp{ls -l /dev/zero}.
-If the output isn't basically the
-same, contact your system
-administrator about restoring @file{/dev/null} to its proper status).
-
-This bug is particularly insidious because removing @file{/dev/null} as
-a special file can go undetected for quite a while, aside from
-various applications and programs exhibiting sudden, strange
-behaviors.
-
-I sincerely apologize for not realizing the
-implications of the fact that when @samp{g77 -v} runs the @command{ld} command
-with @samp{-o /dev/null} that @command{ld} tries to @emph{remove} the executable
-it is supposed to build (especially if it reports unresolved
-references, which it should in this case)!
-
-@item
-Fix crash on @samp{CHARACTER*(*) FOO} in a main or block data program unit.
-
-@item
-Fix crash that can occur when diagnostics given outside of any
-program unit (such as when input file contains @samp{@@foo}).
-
-@item
-Fix crashes, infinite loops (hangs), and such involving diagnosed code.
-
-@item
-Fix @code{ASSIGN}'ed variables so they can be @code{SAVE}'d or dummy arguments,
-and issue clearer error message in cases where target of @code{ASSIGN}
-or @code{ASSIGN}ed @code{GOTO}/@code{FORMAT} is too small (which should
-never happen).
-
-@item
-Make @code{libf2c} build procedures work on more systems again by
-eliminating unnecessary invocations of @samp{ld -r -x} and @command{mv}.
-
-@item
-Fix omission of @option{-funix-intrinsics-@dots{}} options in list of permitted
-options to compiler.
-
-@item
-Fix failure to always diagnose missing type declaration for
-@code{IMPLICIT NONE}.
-
-@item
-Fix compile-time performance problem (which could sometimes
-crash the compiler, cause a hang, or whatever, due to a bug
-in the back end) involving exponentiation with a large @code{INTEGER}
-constant for the right-hand operator (e.g. @samp{I**32767}).
-
-@item
-Fix build procedures so cross-compiling @command{g77} (the @command{fini}
-utility in particular) is properly built using the host compiler.
-
-@item
-Add new @option{-Wsurprising} option to warn about constructs that are
-interpreted by the Fortran standard (and @command{g77}) in ways that
-are surprising to many programmers.
-
-@item
-Add @code{ERF()} and @code{ERFC()} as generic intrinsics mapping to existing
-@code{ERF}/@code{DERF} and @code{ERFC}/@code{DERFC} specific intrinsics.
-
-@emph{Note:} You should
-specify @samp{INTRINSIC ERF,ERFC} in any code where you might use
-these as generic intrinsics, to improve likelihood of diagnostics
-(instead of subtle run-time bugs) when using a compiler that
-doesn't support these as intrinsics (e.g. @command{f2c}).
-
-@item
-Remove from @option{-fno-pedantic} the diagnostic about @code{DO}
-with non-@code{INTEGER} index variable; issue that under
-@option{-Wsurprising} instead.
-
-@item
-Clarify some diagnostics that say things like ``ignored'' when that's
-misleading.
-
-@item
-Clarify diagnostic on use of @code{.EQ.}/@code{.NE.} on @code{LOGICAL}
-operands.
-
-@item
-Minor improvements to code generation for various operations on
-@code{LOGICAL} operands.
-
-@item
-Minor improvement to code generation for some @code{DO} loops on some
-machines.
-
-@item
-Support @command{gcc} version 2.7.1.
-

-Upgrade to @code{libf2c} as of 1995-11-15.
-@end itemize
-
-@c 1995-08-30: 0.5.16 released.
-@heading In 0.5.16:
-@itemize @bullet
-@item
-Fix a code-generation bug involving complicated @code{EQUIVALENCE} statements
-not involving @code{COMMON}.
-
-@item
-Fix code-generation bugs involving invoking ``gratis'' library procedures
-in @code{libf2c} from code compiled with @option{-fno-f2c} by making these
-procedures known to @command{g77} as intrinsics (not affected by -fno-f2c).
-This is known to fix code invoking @code{ERF()}, @code{ERFC()},
-@code{DERF()}, and @code{DERFC()}.
-
-@item
-Update @code{libf2c} to include netlib patches through 1995-08-16, and
-@code{#define} @code{WANT_LEAD_0} to 1 to make @command{g77}-compiled code more
-consistent with other Fortran implementations by outputting
-leading zeros in formatted and list-directed output.
-
-@item
-Fix a code-generation bug involving adjustable dummy arrays with high
-bounds whose primaries are changed during procedure execution, and
-which might well improve code-generation performance for such arrays
-compared to @command{f2c} plus @command{gcc} (but apparently only when using
-@file{gcc-2.7.0} or later).
-
-@item
-Fix a code-generation bug involving invocation of @code{COMPLEX} and
-@code{DOUBLE COMPLEX} @code{FUNCTION}s and doing @code{COMPLEX} and
-@code{DOUBLE COMPLEX} divides, when the result
-of the invocation or divide is assigned directly to a variable
-that overlaps one or more of the arguments to the invocation or divide.
-
-@item
-Fix crash by not generating new optimal code for @samp{X**I} if @samp{I} is
-nonconstant and the expression is used to dimension a dummy
-array, since the @command{gcc} back end does not support the necessary
-mechanics (and the @command{gcc} front end rejects the equivalent
-construct, as it turns out).
-
-@item
-Fix crash on expressions like @samp{COMPLEX**INTEGER}.
-
-@item
-Fix crash on expressions like @samp{(1D0,2D0)**2}, i.e. raising a
-@code{DOUBLE COMPLEX} constant to an @code{INTEGER} constant power.
-
-@item
-Fix crashes and such involving diagnosed code.
-
-@item
-Diagnose, instead of crashing on, statement function definitions
-having duplicate dummy argument names.
-
-@item
-Fix bug causing rejection of good code involving statement function
-definitions.
-
-@item
-Fix bug resulting in debugger not knowing size of local equivalence
-area when any member of area has initial value (via @code{DATA},
-for example).
-
-@item
-Fix installation bug that prevented installation of @command{g77} driver.
-Provide for easy selection of whether to install copy of @command{g77}
-as @command{f77} to replace the broken code.
-
-@item
-Fix @command{gcc} driver (affects @command{g77} thereby) to not
-gratuitously invoke the
-@code{f771} program (e.g. when @option{-E} is specified).
-
-@item
-Fix diagnostic to point to correct source line when it immediately
-follows an @code{INCLUDE} statement.
-
-@item
-Support more compiler options in @command{gcc}/@command{g77} when
-compiling Fortran files.
-These options include @option{-p}, @option{-pg}, @option{-aux-info}, @option{-P},
-correct setting of version-number macros for preprocessing, full
-recognition of @option{-O0}, and
-automatic insertion of configuration-specific linker specs.
-
-@item
-Add new intrinsics that interface to existing routines in @code{libf2c}:
-@code{ABORT}, @code{DERF}, @code{DERFC}, @code{ERF}, @code{ERFC}, @code{EXIT},
-@code{FLUSH}, @code{GETARG}, @code{GETENV}, @code{IARGC},
-@code{SIGNAL}, and @code{SYSTEM}.
-Note that @code{ABORT}, @code{EXIT}, @code{FLUSH}, @code{SIGNAL}, and
-@code{SYSTEM} are intrinsic subroutines, not functions (since they
-have side effects), so to get the return values from @code{SIGNAL}
-and @code{SYSTEM}, append a final argument specifying an @code{INTEGER}
-variable or array element (e.g. @samp{CALL SYSTEM('rm foo',ISTAT)}).
-
-@item
-Add new intrinsic group named @code{unix} to contain the new intrinsics,
-and by default enable this new group.
-
-@item
-Move @code{LOC()} intrinsic out of the @code{vxt} group to the new
-@code{unix} group.
-
-@item
-Improve @command{g77} so that @samp{g77 -v} by itself (or with
-certain other options, including @option{-B}, @option{-b}, @option{-i},
-@option{-nostdlib}, and @option{-V}) reports lots more useful
-version info, and so that long-form options @command{gcc} accepts are
-understood by @command{g77} as well (even in truncated, unambiguous forms).
-
-@item
-Add new @command{g77} option @option{--driver=name} to specify driver when
-default, @command{gcc}, isn't appropriate.
-
-@item
-Add support for @samp{#} directives (as output by the preprocessor) in the
-compiler, and enable generation of those directives by the
-preprocessor (when compiling @samp{.F} files) so diagnostics and debugging
-info are more useful to users of the preprocessor.
-
-@item
-Produce better diagnostics, more like @command{gcc}, with info such as
-@samp{In function `foo':} and @samp{In file included from...:}.
-
-@item
-Support @command{gcc}'s @option{-fident} and @option{-fno-ident} options.
-
-@item
-When @option{-Wunused} in effect, don't warn about local variables used as
-statement-function dummy arguments or @code{DATA} implied-@code{DO} iteration
-variables, even though, strictly speaking, these are not uses
-of the variables themselves.
-
-@item
-When @samp{-W -Wunused} in effect, don't warn about unused dummy arguments
-at all, since there's no way to turn this off for individual
-cases (@command{g77} might someday start warning about these)---applies
-to @command{gcc} versions 2.7.0 and later, since earlier versions didn't
-warn about unused dummy arguments.
-
-@item
-New option @option{-fno-underscoring} that inhibits transformation of names
-(by appending one or two underscores) so users may experiment
-with implications of such an environment.
-
-@item
-Minor improvement to @file{gcc/f/info} module to make it easier to build
-@command{g77} using the native (non-@command{gcc}) compiler on certain machines
-(but definitely not all machines nor all non-@command{gcc} compilers).
-Please
-do not report bugs showing problems compilers have with
-macros defined in @file{gcc/f/target.h} and used in places like
-@file{gcc/f/expr.c}.
-
-@item
-Add warning to be printed for each invocation of the compiler
-if the target machine @code{INTEGER}, @code{REAL}, or @code{LOGICAL} size
-is not 32 bits,
-since @command{g77} is known to not work well for such cases.
-
-@item
-Lots of new documentation (though work is still needed to put it into
-canonical GNU format).
-
-@item
-Build @code{libf2c} with @option{-g0}, not @option{-g2}, in effect
-(by default), to produce
-smaller library without lots of debugging clutter.

-New @option{-ffixed-line-length-@var{n}} option, where @var{n} is the

-that characters beyond column @var{n} are ignored, or @var{n} is @samp{none},
-meaning no characters are ignored.

-No longer generate better code for some kinds of array references,

-turned out to slow down some code in some cases after all.
-
-@item
-In @code{COMMON} and @code{EQUIVALENCE} areas with any members given initial
-values (e.g. via @code{DATA}), uninitialized members now always
-initialized to binary zeros (though this is not required by
-the standard, and might not be done in future versions
-of @command{g77}).
-Previously, in some @code{COMMON}/@code{EQUIVALENCE} areas
-(essentially those with members of more than one type), the
-uninitialized members were initialized to spaces, to
-cater to @code{CHARACTER} types, but it seems no existing code expects
-that, while much existing code expects binary zeros.

-Remove all the @command{g77}-specific auto-configuration scripts, code,

-except for temporary substitutes for bsearch() and strtoul(), as

-People will have to fix their systems' problems themselves, or at

-@option{-Wall} now implies @option{-Wuninitialized} as with @command{gcc}
-(i.e. unless @option{-O} not specified, since @option{-Wuninitialized}
-requires @option{-O}), and implies @option{-Wunused} as well.
-
-@item
-@option{-Wunused} no longer gives spurious messages for unused
-@code{EXTERNAL} names (since they are assumed to refer to block data
-program units, to make use of libraries more reliable).
-
-@item
-Support @code{%LOC()} and @code{LOC()} of character arguments.
-
-@item
-Support null (zero-length) character constants and expressions.
-
-@item
-Support @command{f2c}'s @code{IMAG()} generic intrinsic.
-
-@item
-Support @code{ICHAR()}, @code{IACHAR()}, and @code{LEN()} of
-character expressions that are valid in assignments but
-not normally as actual arguments.
-
-@item
-Support @command{f2c}-style @samp{&} in column 1 to mean continuation line.
-
-@item
-Allow @code{NAMELIST}, @code{EXTERNAL}, @code{INTRINSIC}, and @code{VOLATILE}
-in @code{BLOCK DATA}, even though these are not allowed by the standard.
-
-@item
-Allow @code{RETURN} in main program unit.
-
-@item
-Changes to Hollerith-constant support to obey Appendix C of the
-standard:
-
-@itemize @minus
-@item
-Now padded on the right with zeros, not spaces.
-
-@item
-Hollerith ``format specifications'' in the form of arrays of
-non-character allowed.
-
-@item
-Warnings issued when non-space truncation occurs when converting
-to another type.
-
-@item
-When specified as actual argument, now passed
-by reference to @code{INTEGER} (padded on right with spaces if constant
-too small, otherwise fully intact if constant wider the @code{INTEGER}
-type) instead of by value.
-@end itemize
-
-@strong{Warning:} @command{f2c} differs on the
-interpretation of @samp{CALL FOO(1HX)}, which it treats exactly the
-same as @samp{CALL FOO('X')}, but which the standard and @command{g77} treat
-as @samp{CALL FOO(%REF('X '))} (padded with as many spaces as necessary
-to widen to @code{INTEGER}), essentially.
-
-@item
-Changes and fixes to typeless-constant support:
-
-@itemize @minus
-@item
-Now treated as a typeless double-length @code{INTEGER} value.
-
-@item
-Warnings issued when overflow occurs.
-
-@item
-Padded on the left with zeros when converting
-to a larger type.
-
-@item
-Should be properly aligned and ordered on
-the target machine for whatever type it is turned into.
-
-@item
-When specified as actual argument, now passed as reference to
-a default @code{INTEGER} constant.
-@end itemize
-
-@item
-@code{%DESCR()} of a non-@code{CHARACTER} expression now passes a pointer to
-the expression plus a length for the expression just as if
-it were a @code{CHARACTER} expression.
-For example, @samp{CALL FOO(%DESCR(D))}, where
-@samp{D} is @code{REAL*8}, is the same as @samp{CALL FOO(D,%VAL(8)))}.
-
-@item
-Name of multi-entrypoint master function changed to incorporate
-the name of the primary entry point instead of a decimal
-value, so the name of the master function for @samp{SUBROUTINE X}
-with alternate entry points is now @samp{__g77_masterfun_x}.
-
-@item
-Remove redundant message about zero-step-count @code{DO} loops.
-
-@item
-Clean up diagnostic messages, shortening many of them.
-
-@item
-Fix typo in @command{g77} man page.
-
-@item
-Clarify implications of constant-handling bugs in @file{f/BUGS}.
-
-@item
-Generate better code for @samp{**} operator with a right-hand operand of
-type @code{INTEGER}.
-
-@item
-Generate better code for @code{SQRT()} and @code{DSQRT()},
-also when @option{-ffast-math}
-specified, enable better code generation for @code{SIN()} and @code{COS()}.
-
-@item
-Generate better code for some kinds of array references.
-
-@item
-Speed up lexing somewhat (this makes the compilation phase noticeably
-faster).

- Description:
- The high-level input level to statement handling for the rest of the
- FFE. ffest_first is the first state for the lexer to invoke to start
- a statement. A statement normally starts with a NUMBER token (to indicate
- a label def) followed by a NAME token (to indicate what kind of statement
- it is), though of course the NUMBER token may be omitted. ffest_first
- gathers the first NAME token and returns a state of ffest_second_,
- where the trailing underscore means "internal to ffest" and thus outside
- users should not depend on this. ffest_second_ then looks at the second
- token in conjunction with the first, decides what possible statements are
- meant, and tries each possible statement in turn, from most likely to
- least likely. A successful attempt currently is recorded, and further
- successful attempts by other possibilities raise an assertion error in
- ffest_confirmed (this is to detect ambiguities). A failure in an
- attempt is signaled by calling ffest_ffebad_start; this results in the
- next token sent by ffest_save_ (the intermediary when more than one
- possible statement exists) being EOS to shut down processing and the next
- possibility tried.
-
- When all possibilities have been tried, the successful one is retried with
- inhibition turned off (FALSE) as reported by ffest_is_inhibited(). If
- there is no successful one, the first one is retried so the user gets to
- see the error messages.
-
- In the future, after syntactic bugs have been reasonably shaken out and
- ambiguities thus detected, the first successful possibility will be
- enabled (inhibited goes FALSE) as soon as it confirms success by calling
- ffest_confirmed, thus retrying the possibility will not be necessary.
-
- The only complication in all this is that expression handling is
- happening while possibilities are inhibited. It is up to the expression
- handler, conceptually, to not make any changes to its knowledge base for
- variable names and so on when inhibited that cannot be undone if
- the current possibility fails (shuts down via ffest_ffebad_start). In
- fact, this business is handled not be ffeexpr, but by lower levels.
-
- ffesta functions serve only to provide information used in syntactic
- processing of possible statements, and thus may not make changes to the
- knowledge base for variables and such.
-
- ffestb functions perform the syntactic analysis for possible statements,
- and thus again may not make changes to the knowledge base except under the
- auspices of ffeexpr and its subordinates, changes which can be undone when
- necessary.
-
- ffestc functions perform the semantic analysis for the chosen statement,
- and thus may change the knowledge base as necessary since they are invoked
- by ffestb functions only after a given statement is confirmed and
- enabled. Note, however, that a few ffestc functions (identified by
- their statement names rather than grammar numbers) indicate valid forms
- that are, outside of any context, ambiguous, such as ELSE WHERE and
- PRIVATE; these functions should make a quick decision as to what is
- intended and dispatch to the appropriate specific ffestc function.
-
- ffestd functions actually implement statements. When called, the
- statement is considered valid and is either an executable statement or
- a nonexecutable statement with direct-output results. For example, CALL,
- GOTO, and assignment statements pass through ffestd because they are
- executable; DATA statements pass through because they map directly to the
- output file (or at least might so map); ENTRY statements also pass through
- because they essentially affect code generation in an immediate way;
- whereas INTEGER, SAVE, and SUBROUTINE statements do not go through
- ffestd functions because they merely update the knowledge base.

- Description:
- Parses the proper form for statements, builds up expression trees for
- them, but does not actually implement them. Uses ffebad (primarily via
- ffesta_ffebad_start) to indicate errors in form. In many cases, an invalid
- statement form indicates another possible statement needs to be looked at
- by ffest. In a few cases, a valid statement form might not completely
- determine the nature of the statement, as in REALFUNCTIONA(B), which is
- a valid form for either the first statement of a function named A taking
- an argument named B or for the declaration of a real array named FUNCTIONA
- with an adjustable size of B. A similar (though somewhat easier) choice
- must be made for the statement-function-def vs. assignment forms, as in
- the case of FOO(A) = A+2.0.
-
- A given parser consists of one or more state handlers, the first of which
- is the initial state, and the last of which (for any given input) returns
- control to a final state handler (ffesta_zero or ffesta_two, explained
- below). The functions handling the states for a given parser usually have
- the same names, differing only in the final number, as in ffestb_foo_
- (handles the initial state), ffestb_foo_1_, ffestb_foo_2_ (handle
- subsequent states), although liberties sometimes are taken with the "foo"
- part either when keywords are clarified into given statements or are
- transferred into other possible areas. (For example, the type-name
- states can hop over to _dummy_ functions when the FUNCTION or RECURSIVE
- keywords are seen, though this kind of thing is kept to a minimum.) Only
- the names without numbers are exported to the rest of ffest; the others
- are local (static).
-
- Each initial state is provided with the first token in ffesta_tokens[0],
- which will be killed upon return to the final state (ffesta_zero or
- ffelex_swallow_tokens passed through to ffesta_zero), so while it may
- be changed to another token, a valid token must be left there to be
- killed. Also, a "convenient" array of tokens are left in
- ffesta_tokens[1..FFESTA_tokensMAX]. The initial state of this set of
- elements is undefined, thus, if tokens are stored here, they must be
- killed before returning to the final state. Any parser may also use
- cross-state local variables by sticking a structure containing storage
- for those variables in the local union ffestb_local_ (unless the union
- goes on strike). Furthermore, parsers that handle more than one first or
- second tokens (like _varlist_, which handles EXTERNAL, INTENT, INTRINSIC,
- OPTIONAL,
- PUBLIC, or PRIVATE, and _endxyz_, which handles ENDBLOCK, ENDBLOCKDATA,
- ENDDO, ENDIF, and so on) may expect arguments from ffest in the
- ffest-wide union ffest_args_, the substructure specific to the parser.
-
- A parser's responsibility is: to call either ffesta_confirmed or
- ffest_ffebad_start before returning to the final state; to be the only
- parser that can possibly call ffesta_confirmed for a given statement;
- to call ffest_ffebad_start immediately upon recognizing a bad token
- (specifically one that another statement parser might confirm upon);
- to call ffestc functions only after calling ffesta_confirmed and only
- when ffesta_is_inhibited returns FALSE; and to call ffesta_is_inhibited
- only after calling ffesta_confirmed. Confirm as early as reasonably
- possible, even when only one ffestc function is called for the statement
- later on, because early confirmation can enhance the error-reporting
- capabilities if a subsequent error is detected and this parser isn't
- the first possibility for the statement.
-
- To assist the parser, functions like ffesta_ffebad_1t and _1p_ have
- been provided to make use of ffest_ffebad_start fairly easy.

-
- Description:
- Verifies the proper semantics for statements, checking expressions already
- semantically analyzed individually, collectively, checking label defs and
- refs, and so on. Uses ffebad to indicate errors in semantics.
-
- In many cases, both a token and a keyword (ffestrFirst, ffestrSecond,
- or ffestrOther) is provided. ONLY USE THE TOKEN as a pointer to the
- source-code location for an error message or similar; use the keyword
- as the semantic matching for the token, since the token's text might
- not match the keyword's code. For example, INTENT(IN OUT) A in free
- source form passes to ffestc_R519_start the token "IN" but the keyword
- FFESTR_otherINOUT, and the latter is correct.
-
- Generally, either a single ffestc function handles an entire statement,
- in which case its name is ffestc_xyz_, or more than one function is
- needed, in which case its names are ffestc_xyz_start_,
- ffestc_xyz_item_ or ffestc_xyz_item_abc_, and ffestc_xyz_finish_.
- The caller must call _start_ before calling any _item_ functions, and
- must call _finish_ afterwards. If it is clearly a syntactic matter as
- to restrictions on the number and variety of _item_ calls, then the caller
- should report any errors and ffestc_ should presume it has been taken
- care of and handle any semantic problems with grace and no error messages.
- If the permitted number and variety of _item_ calls has some basis in
- semantics, then the caller should not generate any messages and ffestc
- should do all the checking.
-
- A few ffestc functions have names rather than grammar numbers, like
- ffestc_elsewhere and ffestc_end. These are cases where the actual
- statement depends on its context rather than just its form; ELSE WHERE
- may be the obvious (WHERE...ELSE WHERE...END WHERE) or something a little
- more subtle (WHERE: IF THEN...ELSE WHERE...END IF WHERE). The actual
- ffestc functions do exist and do work, but may or may not be invoked
- by ffestb depending on whether some form of resolution is possible.
- For example, ffestc_R1103 end-program-stmt is reachable directly when
- END PROGRAM [name] is specified, or via ffestc_end when END is specified
- and the context is a main program. So ffestc_xyz_ should make a quick
- determination of the context and pick the appropriate ffestc_Nxyz_
- function to invoke, without a lot of ceremony.

-/* "How g77 learns about symbols"
-
- There are three primary things in a symbol that g77 uses to keep
- track of what it has learned about that symbol:
-
- 1. The state
- 2. The attributes
- 3. The info
-
- State, attributes, and info (see f-info* files) all start out with
- "NONE" fields when a symbol is first created.
-
- In a PROGRAM or BLOCK DATA program unit, info where cannot be DUMMY
- or RESULT. Any combinations including those possibilities are not
- considered possible in such program units.
-
- As soon as a symbol is created, it _must_ have its state changed to
- SEEN, UNCERTAIN, or UNDERSTOOD.
-
- If SEEN, some info might be set, such as the type info (as in when
- the TYPE attribute is present) or kind/where info.
-
- If UNCERTAIN, the permitted combinations of attributes and info are
- listed below. Only the attributes ACTUALARG, ADJUSTABLE, ANYLEN, ARRAY,
- DUMMY, EXTERNAL, SFARG, and TYPE are permitted. (All these attributes
- are contrasted to each attribute below, even though some combinations
- wouldn't be permitted in SEEN state either.) Note that DUMMY and

- If UNDERSTOOD, the attributes are no longer considered, and the info
- field is considered to be as fully filled in as possible by analyzing
- a single program unit.
-
- Each of the attributes (used only for SEEN/UNCERTAIN states) is
- defined and described below. In many cases, a symbol starts out as
- SEEN and has attributes set as it is seen in various contexts prior
- to the first executable statement being seen (the "exec transition").
- Once that happens, either it becomes immediately UNDERSTOOD and all
- its info filled in, or it becomes UNCERTAIN and its info only partially
- filled in until it becomes UNDERSTOOD. While UNCERTAIN, only a
- subset of attributes are possible/important.
-
- Not all symbols reach the UNDERSTOOD state, and in some cases symbols
- go immediately from NONE to the UNDERSTOOD or even UNCERTAIN state.
- For example, given "PROGRAM FOO", everything is known about the name
- "FOO", so it becomes immediately UNDERSTOOD.
-
- Also, there are multiple name spaces, and not all attributes are
- possible/permitted in all name spaces.
-
- The only attributes permitted in the global name space are:
-
- ANY, CBLOCK, SAVECBLOCK.
-
- The only attributes permitted in the local name space are:
-
- ANY, ACTUALARG, ADJUSTABLE, ADJUSTS, ANYLEN, ANYSIZE, ARRAY, COMMON,
- DUMMY, EQUIV, EXTERNAL, INIT, INTRINSIC, NAMELIST, RESULT, SAVE, SFARG,
- SFUNC, TYPE.
-
- In the stmt-func name space, no attributes are used, just the states.

- Description:
- Implements conversion of lexer tokens to machine-dependent numerical
- form and accordingly issues diagnostic messages when necessary.
-
- Also, this module, especially its .h file, provides nearly all of the
- information on the target machine's data type, kind type, and length
- type capabilities. The idea is that by carefully going through
- target.h and changing things properly, one can accomplish much
- towards the porting of the FFE to a new machine. There are limits
- to how much this can accomplish towards that end, however. For one
- thing, the ffeexpr_collapse_convert function doesn't contain all the
- conversion cases necessary, because the text file would be
- enormous (even though most of the function would be cut during the
- cpp phase because of the absence of the types), so when adding to
- the number of supported kind types for a given type, one must look
- to see if ffeexpr_collapse_convert needs modification in this area,
- in addition to providing the appropriate macros and functions in
- ffetarget. Note that if combinatorial explosion actually becomes a
- problem for a given machine, one might have to modify the way conversion
- expressions are built so that instead of just one conversion expr, a
- series of conversion exprs are built to make a path from one type to
- another that is not a "near neighbor". For now, however, with a handful
- of each of the numeric types and only one character type, things appear
- manageable.
-
- A nonobvious change to ffetarget would be if the target machine was
- not a 2's-complement machine. Any item with the word "magical" (case-
- insensitive) in the FFE's source code (at least) indicates an assumption
- that a 2's-complement machine is the target, and thus that there exists
- a magnitude that can be represented as a negative number but not as
- a positive number. It is possible that this situation can be dealt
- with by changing only ffetarget, for example, on a 1's-complement
- machine, perhaps #defineing ffetarget_constant_is_magical to simply
- FALSE along with making the appropriate changes in ffetarget's number
- parsing functions would be sufficient to effectively "comment out" code
- in places like ffeexpr that do certain magical checks. But it is
- possible there are other 2's-complement dependencies lurking in the
- FFE (as possibly is true of any large program); if you find any, please
- report them so we can replace them with dependencies on ffetarget
- instead.
