- * config/tm-next.h (GO_IF_INDEXABLE_BASE): Don't use pc

- at the start of the .srcinfo section for each compilation unit,
- and the contents of the "special" final entry in the .srcinfo
- section have changed (to { -1, -1 }).
+1999-12-21 Bernd Schmidt <bernds@cygnus.co.uk>

- to be generated whenever the corresponding extended attribute
- codes are defined (presumably within a modified dwarf.h file).
+ * reload1.c (emit_reload_insns): Break out code and variables into...
+ (input_reload_insns, other_input_address_reload_insns,

- * dwarfout.c: use the section names .srcinfo and .sources rather
- than .finfo and .files. The additional specificity is warranted
- because the DWARF information may someday include information
- about object files as well as source files.
+Tue Dec 21 07:06:36 1999 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
- * dwarfout.c: fixed a bug where a type attribute was being generated
- for functions and function types even when the return type was
- void. "Standard" dwarf says that if the return type for a function
- or function type is void then no type attribute should be generated
- for the corresponding DIE.

- (call): Fix typo which had %o7 being emitted as %o.
- (various patterns): Fixed places where match_operand had the wrong
- operand number.
-
-Sat Dec 29 17:27:00 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * sparc.md: cc_status no longer handles condition code updates.
- Instead, condition codes are explicitly set and used via
- hard register 0. Special attributes specific to condition codes
- (such as whether conditional branches should test the integer or
- floating-point condition codes, or that the condition codes cannot
- be tested for a condition which would test the overflow bit) are
- handled by encoding the attribute in the mode for the condition
- code register.
- (type attributes): type "unary" insns have one input operand (1)
- and one output operand (0)
- type "binary" insns have two input operands (1,2) and one output (0)
- type "compare" insns have one or two input operands (0,1) and no output
- type "move" and type "arith" have been deleted.
- (prescan attribute): Deleted. Machine description now puts
- floating-point zero in registers when needed.
- (use_cc attribute): Deleted.
- (fpcc define_delay): No longer depend on "use_cc" attribute.
- Also, fpcc delay characteristics hold for "fpcc" type insns.
- (cc attribute): Deleted.
- (cmpxx patterns): Now written as `define_expand's so we can stow
- away operands. When the pattern that will use the results of the
- conditional test is emitted, it can use these operands to figure
- out the right way to emit the compare.
- (bcc patterns): Rewritten to emit comparison (based on stowed-away
- info) before emitting branch.
- (scc patterns): Handle all the cases with branch-free code.
- Added new pattern to recognize (x + (i == 0)).
- (movsi pattern recognizer): Split into two patterns so that e.g.
- "(set:SI (mem:SI ...) (const_int 5))" is never considered valid.
- Instead this has to be a two-insn sequence.
- (mov{hq}i pattern recognizers): Ditto.
- (movstrsi): Force operands[2] out of memory if it was in memory.
- ({zero,sign}_extendXY): Now written as `define_expand's instead of
- `define_insn's for more accurate machine modeling.
- Added new pattern to optimize bit-field compares.
- (floatsisf2 patterns): Delete redundant setting of "in_call_delay"
- attribute.
- (fix_trunc{sf,df}si2 pattern): Use clobberable register in which
- the conversion can take place. Used to use %f30,%f31.
- ({add,sub}di3 pattern): Put explicit clobber of (reg 0) in the
- pattern.
- (negdi2 pattern): Ditto.
- Added new patterns to handle merging of addition/subtraction with
- condition code testing (with (reg:CC_NOOV 0)).
- ({and,ior,xor}cbsi3 pattern): Obsolete. Deleted.
- Added patterns to represent setting of condition codes in addition
- to performing logical operations.
- ({neg,abs}df2 pattern): Use `R' print letter to overcome the need
- to use a C action instead of a simple template.
- (ash{l,r}{hi,qi}3): Define patterns for shifts on sub-SImode
- operands.
- (jump pattern): Use `*' print code to obviate the need for a C
- action when a template can do.
- (tablejump pattern): Ditto, with `^' code as well.
- Deleted `define_split's that were used to handle mem-mem moves in
- the case of PIC generation. Since all move insns are emitted and
- maintained as SPARC-valid insns, these should no longer be needed.
- (various patterns): (HI ...) is spelled (HI:SI ...). Also, use
- `gen_lowpart' instead of building subregs directly.
- New `define_split's were added to split scc insns into simpler
- components which have single-insn templates.
- Fixed a return peephole when returning a SFmode value (it was
- missing the "ret"!).
- Lots of complicated peepholes that brought cc testing and
- arithmetic operations together were deleted. This is because the
- combiner should now handle all these cases.
-
- * out-sparc.c (sparc_compare_op{0,1}): New global variables.
- Used to hold the operand(s) to compare insns in lieu of emitting a
- compare.
- (reg_or_cc0_operand): Deleted.
- (normal_comp_operator): New function.
- (cc_arithop): Now returns 0 for PLUS and MINUS.
- (cc_arithopn): Now returns 0 for XOR.
- (gen_compare_reg): New function.
- (sparc_address_cost): Simplified because it turns out it doesn't
- matter what is returned for illegitimate addresses.
- (hard_regno_mode_ok): Updated to use these new #defines.
- (C_MODES): New #define, for condition code modes.
- (S_MODES): Ditto, for single-word (and smaller) quantities.
- (D_MODES): Ditto, for double-word (and smaller) quantities.
- (T_MODES): Ditto, for tetra-word (and smaller) quantities.
- (SF_MODES): Ditto, for SFmode quantities.
- (DF_MODES): Ditto, for SF_MODE, DFmode, SCmode, etc.
- (TF_MODES): Ditto, for DF_MODE, TFmode, DCmode, etc.
- (output_floatsi{df,sf}2): Greatly simplified.
- (output_pic_sequence,output_pic_sequence_2,fp_zero_hook,
- output_tail_call): Turned off.
-
- * tm-sparc.h (ASM_SPEC): Pass `-k' to assembler if compiling PIC.
- (WORDS_BIG_ENDIAN): Define as 1, not 0.
- (FIXED_REGISTERS): %f30 and %f31 are now allocatable.
- (REG_CC0_RTX, CC0_REGNUM): Deleted.
- (EXTRA_CC_MODES): New modes CC_NOOVmode and CCFPmode. The former
- is for when the overflow bit it not to be tested; the latter is
- for when the condition is sitting in the floating point unit.
- (SELECT_CC_MODE): New macro.
- (FINAL_PRESCAN_INSN): Deleted.
- (CC_* macros): Deleted.
- (PRINT_OPERAND_PUNCT_VALID_P): New valid chars are '#' (for
- whether to print a noop or not), '*' (for whether to print a ",a"
- or not), and '^' (for whether to emit code for PIC branch or not).
- (PRINT_OPERAND{,_ADDRESS}): Replace calls to fprintf by calls to
- fputs where that is convenient.
-
- * expr.h, cplus-dbxout.c: #ifdef BYTES_BIG_ENDIAN should be #if.
-
- * reload.c (struct replacement): Add new field subreg_loc.
- (push_reload): If reloading SUBREG_REG of a paradoxical SUBREG,
- store the location of the SUBREG in subreg_loc in REPLACEMENTS.
- (push_replacement): Initialize subreg_loc.
- (subst_reloads): Don't produce nested SUBREGs; use subreg_loc.
-
- * regclass.c (regclass): Handle (set X (op CONST Y)) properly when
- the modes of operands 0 and 1 are different.

- Accepts an argument saying how to normalize the result and does
- appropriate normalization.

- to nesting structure (new type stmt_nesting).
- (expand_exit_loop{,_if_false},expand_continue_loop): Accept pointer

- (like C's continue and break stmts) can refer to other than the
- innermost loop.
- (expand_start_cond): Uses new names for if-related labels that
- reflect addition of "elseif" call, and sets endif_label to whatever
- exit_label gets set to (so we don't generate two identical labels
- for languages from which if is exitable via expand_exit_something).
- (expand_start_elseif): New function, used by Fortran.
- (expand_start_else): Moved above _end_cond so these four functions
- appear in the order they get called; uses new names, and fills in
- only endif_label if needed, not exit_label.
- (expand_end_cond): Handles end of any if, not just if-without-else.
- Generates both labels for next else/elseif pending (there was none)
- and the endif itself, if they exist (and there will always be at least
- one).
- (expand_end_else): Gone, call expand_end_cond instead.
- * c-parse.y, cplus-parse.y, objc-parse.y: Pass new 0 argument to
- expand_..._loop_... to indicate the innermost loop; call
- expand_end_cond instead of expand_end_else.
- * tree.h: Typedef for stmt_nesting returned by expand_start_loop...
- and change their return types accordingly.

-
- * dwarfout.c (lookup_filename, dwarfout_finalize): changed from
- maintaining a linked list of filename entries to maintaining an
- (expandable) array of filename entries instead. Also, changed
- code so that *all* filename strings are output (to the .files
- section of the asm file) in one swell foop just as the asm file is
- being finalized rather than writing out new filenames one-by-one
- as they arise (as previously). This circumvents a problem caused
- by rfg's naive assumption that assemblers kept a stack of prior
- section names (of depth > 1) which could be successively popped
- via multiple `previous' directives. For some assemblers, the
- depth of the stack is only 1 and they can get confused if you do
- two (or more) `previous' directives in a row. Anyway, it is no
- longer either necessary or useful to do that, so who cares.
-
- * dwarfout.c: added code to output newlines to the asm file just
- prior to each and every change of section (for better readability
- of the asm files).
-
- * dwarfout.c: changed code so that if DWARF_DESCRIBE_USED_EXTERNS
- is defined, it forces DWARF_LOCATION_ATTRIBUTES to also be defined.
-
- * dwarfout.c: changed code so that if DWARF_LOCATION_ATTRIBUTES
- is defined, it forces DWARF_DESCRIBE_FILES to be defined (to `1').
-
- * dwarfout.c: changed code so that if DWARF_DESCRIBE_FILES is not
- already defined (in the user's tm.h file) it will automatically be
- defined (by default) to `1'. Also changed all instances of
- `#ifdef DWARF_DESCRIBE_FILES' to `#if DWARF_DESCRIBE_FILES'.
- The user must now intentionally *disable* this feature (by
- defining DWARF_DESCRIBE_FILES to `0' in his tm.h file) if he
- wishes to have the additional information about files suppressed.
-
- * dwarfout.c: changed comments relating to optional defines for
- extended GNU DWARF features to include more information and to
- add some additional clarity.

- of tracking what AND's need to be done and which bits are not

-
- * cplus-decl.c (finish_function): Use CLASSTYPE_ASM_WRITTEN instead
- of TREE_USED to indicate that we need debugging info for
- TTYPE.
- Note that nobody ever sets EXTENDED_DBX_DEBUG. For now,
- change to test DBX_DEBUG. For later, change everything to
- key off of EXTENDED_DBX_DEBUG.

-
- * rtlanal.c (inequality_comparisons_p): Takes new argument
- THIS_CC0_RTX which is the rtl for the condition code value we are
- concerned about testing. All callers changed.
-
- * flow.c (propagate_block,mark_used_regs): Conditionalize
- specialized cc0 handling only if HAVE_cc0 is defined.
-
- * genemit.c (gen_exp): In REG case, If CC0_REGNUM is defined,
- save space by using REG_CC0_RTX instead of allocating a new
- (REG, mode, CC0_REGNUM) rtx if the mode is SImode.
-
- * final.c (output_addr_const): Handle PC for P.I.C. code generation.
- Also, put parens around CONST expressions so that precedence can be
- maintained.
- * final.c (final_scan_insn): Don't look for redunant compares
- except when HAVE_cc0 is defined.
- Also, use `find_cc' to locate the rtx functioning as the
- condition code register in order to perform appropriate calls
- to `alter_cond'.
-
- * expr.c (expand_expr): Supply missing arg in calls to `store_expr'.
-
- * expmed.c (emit_store_flag): New argument COMPARISON is the
- comparison operation whose result we store.
-
- * recog.c (offsettable_address_p,adj_offsettable_operand): Use
- `plus_constant_for_output' instead of `plus_constant' since we
- are testing conditions which rely on being able to add small
- offsets to e.g. LO_SUM operands.
- * explow.c (plus_constant): No special handling for LO_SUM. It is
- not valid to add a constant to a term with LO_SUM, since the
- constant may need to be added to the high bits that form the sum,
- and those high bits are not readily available.
- * explow.c (plus_constant_for_output): Same as `plus_constant'
- except that we do allow adding constants to LO_SUM terms. This
- function works only in special cases such as for
- `adj_offsettable_operand' and `offsettable_address_p'.
-
- * emit-rtl.c: Declare reg_cc0_rtx which is like cc0_rtx, but
- is a register instead of a special form. reg_cc0_rtx should
- be used when representing the condition code register on a
- machine where condition codes are only set if explicitly set.
- For machines which allow arbitrary registers to be used as
- condition code registers (such as the MIPS and 88k), normal
- pseudo registers should be used instead.
- * emit-rtl.c (next_cc0_user,prev_cc0_setter): Conditionalized
- on HAVE_cc0.
- * emit-rtl.c (find_cc): New function. Given INSN, returns
- the rtx of what functions as the condition code register for
- INSN. On machines which use cc0_rtx, this is always cc0_rtx.
- On machines which have a dedicated register for cc0, this is
- that register. On machines which allocate pseudos for holding
- condition codes, this is the pseudo found in a REG_CC0 note.
- Otherwise, this function returns 0.
- * emit-rtl.c (init_emit_once): Allocate `reg_cc0_rtx' if
- CC0_REGNUM is defined.
-
- * cse.c (make_regs_equiv): Don't consider making a reg
- equivalent to another reg whose class is NO_REGS.
- * cse.c (canon_reg): Don't canonicalize a register to
- one whose class is NO_REGS.
- * cse.c (fold_rtx): Conditionalize code for handling cc0_rtx
- with HAVE_cc0.
- * cse.c (predecide_loop_entry): Generalize code to use either
- a register or cc0_rtx.
- * cse.c (cse_insn): Conditionalize code for handling cc0_rtx
- with HAVE_cc0.
-
- * combine.c (combine_instructions,try_combine,subst):
- Conditionalize code handling cc0_rtx with HAVE_cc0.
- * combine.c (simplify_set_cc0_and): Abort if HAVE_cc0 is not
- defined.
- * combine.c (try_distrib): Add break at end of switch cases. It is
- dangerous to leave the last cases of a switch statement to fall
- through since new cases added after will get fallen into.
-
- * recog.c (validate_change): Always succeed for an asm insn,
- since recog always fails to recognize asm insns. This is
- needed for virtual register instantiation in asm insns.
-
- * cse.c (cse_main): When following jumps, notice whether a
- particular basic block causes CSE_JUMPS_ALTERED to become set. When
- this happens, repeat the scan.
- * cse.c (refers_to_mem_p): Changed parameter name REG to BASE,
- which is more accurate. Also, taught it how to cope with
- LO_SUM rtl constructs.

- treat the stack area for the registers as be clobbered by the called

- it if it was previously used for arguments in a similar manner to

- * tree.c: Added facility for gathering statistics on the number of

- statistics are by tree_node_kind, which is almost like using the
- tree code letter, but has more resolution for dealing with different
- kinds of `x' nodes. The facility is enabled by compiling the

+Sun Oct 31 23:42:37 1999 Mark Mitchell <mark@codesourcery.com>
- * cplus-decl.c (finish_function): Always cause returns to jump to
- the return label. This allows -Wreturn to give meaningful error
- messages.
+ * toplev.c (rest_of_compilation): Fix thinko in this change:
- * jump.c (invert_exp): Make this non-static.
- (jump_optimize): Reorganization and simplification of main inner
- loop. Comments added explaining what the optimizers are looking
- for. New optimization added that optimizes for consecutive testing
- of an inequality test followed by an equality test (or vice-versa).
- Changes made to accommodate reorg.c on Sparc. Code for
- cross-jumping return statements was previously dead in this
- function; as a result of the reorganization, it is now live.
- (find_cross_jump): Added temporary variable PREV1 to hold return
- value of `prev_nonnote_insn' instead of calling the function 3 times
- in a row. Also changed so that USE or CLOBBERS are not cross-jumped
- unless some real insns are also cross-jumped. This helps reorg.
- (redirect_jump): Fixed a return that returned no value so that it
- returns 1.
- (rtx_renumbered_equal_p): Test that reg_renumber is nonzero before
- using it. We may want to call this function earlier than by the
- time that array has been initialized.
+ Fri Oct 29 15:25:07 1999 Arnaud Charlet <charlet@ACT-Europe.FR>
- * integrate.c (save_for_inline_{copying,nocopy}): New functions to
- replace `save_for_inline'. save_for_inline_copying saves the rtl
- for inline functions by copying the rtl to the
- maybepermanent_obstack. It is called when the rtl of the current
- function is going to be compiled immediately.
- save_for_inline_nocopy takes advantage of the fact that inline
- function rtl is already allocated to the maybepermanent_obstack, and
- need therefore not be copied if it's not going to be modified by the
- compiler (such as by `rest_of_compilation').
- ({initialize_for,finish}_inline): New helper routines for
- save_for_inline_... functions.
- (note_modified_parmregs): Function called by `mark_stores' to note
- whether parameters are assigned to in the body of an inline
- function.
- New interface, integrate.h, provides declarations for functions used
- by other routines that might want to copy chunks of rtl.
- ({save,try}_constants): Now global (for integrate.h).
- (mark_stores): Ditto.
- (try_fold_condition): Ditto.
-
- * dbxout.c (dbxout_symbol): If a variable belongs to an inline
- function, the decl's rtl may not be rewritten by alter_reg. So if
- we have a variable allocated to a pseudo, just get the hard register
- number from `reg_renumber'.
-
- * varasm.c (output_const_pool): No longer static.
- (assemble_variable): Do output debugging information for global
- register variables. GDB does the right thing for global register
- variables.
+ (rest_of_compilation): If inside an inlined external function,
+ pretend we are just being declared.
+
+Sun Oct 31 23:03:25 1999 Jeffrey A Law (law@cygnus.com)
+
+ * flow.c (calculate_global_regs_live): Fix thinko.
- * toplev.c: New flag `warn_inline' for warning when a function
- declared inline was not in fact inlined. Also, new flag
- `flag_no_inline' which disables function inlining, but retains
- other properties of inline functions (such as lazy compilation
- and write-only-if-needed).
- * toplev.c (compile_file): Changed logic for inline function
- handling to work with `warn_inline' and `flag_no_inline'.
- Also modified to call `save_for_inline_nocopy' when insns are to be
- saved but not immediately compiled.
-
- * function.c (instantiate_decls): If instantiating a function
- which was saved for inline expansion, preserve the rtl created
- by the instantiation as well.
-
- * flags.h (flag_no_inline): New flag; if nonzero, then no
- calls are inlined, regardless of their declaration. We still
- save the insns for these functions in DECL_SAVED_INSNS so that
- the functions need not be written if they are never called.
-
- * calls.c (expand_call): If `flag_no_inline' is set, don't
- inline the call, regardless of whether it was declared inline
- or not.

-
-Thu Oct 18 07:09:06 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * reorg.c: Major reorganization. Many special cases have been moved
- into more general code and an overall restructuring has been done.
- Numerous bugs have been fixed. Highlights:
- (dbr_schedule): First make list of all insns needing filling. Then
- iterate for two passes. In each pass, try two methods of filling
- delay slots, then do some canonicalizations, which may create more
- insns to fill.
- (fill_simple_delay_slots): Now uses list of insns that need filling,
- rather than making such a list.
- Enhance code that finds insns when code paths merge to allow multiple
- uses of the label as long as all uses are in the skipped code.
- (struct resource): Notice volatile memrefs.
- (stop_search_p): Allow option to continue when label is reached.
- (find_end_label, make_return_insns): New functions; when we have a
- filled branch that is really a RETURN, first convert it to a jump
- to a return label and then later see if the insns in the delay slots
- are also valid for a RETURN.
- (mostly_true_jump): Test for branch to loop beginning rather than
- branch at end of loop. Also, conditional return insns predict false.
- (own_thread_p): New function to replace fall_through_to_p.
- (try_merge_delay_insns): Only support merging insns already in an
- insns delay list.
- (get_branch_condition, condition_dominates_p): New functions.
- (steal_delay_list_from_{target,fallthrough}): New functions to
- replace steal_delay_list.
- (redundant_insn_p): New function.
- (update_block, mark_target_live_regs, dbr_schedule): When moving
- an insn not at the front of the basic block to a delay slot,
- leave a "ghost" USE so that we can track things livened and killed.
- (fill_slots_from_thread): Eliminate use of static vars for number
- of slots to fill and already filled.
- Try to modify an insn that follows a register-register copy to use
- the original register; this may create a delay-slot opportunity.
- (try_hoist_target{,_1}): Deleted.
- (relax_delay_slots): Rewritten to just perform canonicalizations
- previously done elsewhere. No actual delay slot filling is done
- here. Any new delay slots created will hopefully be filled in the
- next pass around the loop in dbr_schedule.
-
- * expr.c (emit_push_insn): Don't try to compute a SUBREG of a
- hard register in a non-integer mode when pushing a "partial" arg.
-
- * recog.c (validate_change, apply_change_group): After reload, ensure
- that operands meet the constraints by calling constrain_operands.
- (validate_replace_rtx_1): Consider two rtx equal if they refer to
- the same register.
-
- * jump.c (jump_optimize): Extend change of Oct 16th to handle
- the other usage of find_equiv_reg; remove invalid death notes there.
-
- * rs6000.md, tm-rs6000.h, out-rs6000.c, xm-rs6000.h, make-rs6000:
- New files.
-
- * out-a29k.c (extract_subword): Use gen_{high,low}part from
- an FP CONST_DOUBLE if host and target float formats are the same
- or REAL_IS_NOT_DOUBLE.
-
- * out-romp.c (output_fpop, output_fpops): Provide fr0 as a scratch
- register unless it is used in the insn.
-
- * romp.md: In combined set CC0 and move, optimize case where move
- is nop.
- (DF moves): Fix typo in generation of `get' insn.
- Don't split if input is CONST_DOUBLE because we can't easily
- generate the proper constants.
- (call patterns): Copy data area address via a pseudo to allow
- better CSE'ing.
-
- * tm-romp.h (RTX_COSTS): Memory is expensive, except for a reference
- to our own data area, which is very cheap.
- (ADDRESS_COST): References to the constant pool are as cheap as
- register + offset, since that's what it will be.
-
- * emit-rtl.c (gen_{low,high}part): Can often extract word from FP
- CONST_DOUBLE when host and target floating formats agree.
- (add_insn_after): No longer static.
-
- * reload1.c (reg_equiv_memory_loc): Renamed from reg_equiv_stack_slot
- and now static.
- (reload): If have equivalence with constant that is not a legitimate
- constant operand, force it into memory and handle this as an
- equivalence to memory.
- * reload.h (reg_equiv_stack_loc): Deleted.

- * recog.c (constrain_operands): Recognize pseudo registers as

- execute is now preserved according to their `priority' in the

- list from which they were launched.
- (schedule_block): Removed support for trying to schedule insns
- taking branch delays into account. Reorg.c should be hacked

- (schedule_block): (Re-)compute all register life information here.

- the string comparison function.

- for FIELD_DECLs, make sure we have a FIELD_DECL before proceeding.

- REG_CC_STATUS note), set CC_STATUS to reflect that value.
- (only_leaf_regs_used): @@ For some reason the frame pointer register
- is not marked live, even when it is. If FRAME_POINTER_NEEDED is
- nonzero, set REGS_EVER_LIVE[FRAME_POINTER_REGNUM] to 1.
-
- * expr.c (emit_library_call): Round ARGS_SIZE.CONSTANT up, not down.
- Use new macro MAX to accomplish this.
- (safe_from_p): Don't check that EXP is nonzero. Instead, make
- caller check (only in one place) that argument to `safe_from_p' is
- non-zero.
- (expand_expr): In COND_EXPR case, make sure that the predicate is
- safe from the two conditions. Lossage occured in a construct of the
