1305 * m68k.c (print_operand): For CONST_DOUBLE, treat VOIDmode like DImode.
1307 * expmed.c (init_expmed): Supply missing arg to rtx_cost.
1309 * config/convex/convex.h (LINK_LIBGCC_SPECIAL_1):
1310 Define this instead of LINK_LIBGCC_SPECIAL.
1312 Sat May 8 14:43:27 1993 Torbjorn Granlund (tege@nada.kth.se)
1314 * m68k.md (umulsidi3 expand + two matchers): Rewrite.
1315 Old patterns misused subreg and matched wrong immediate values.
1316 Use const_int_operand and constraint `n' for the immediate arg.
1317 (mulsidi3 patterns): Likewise.
1319 Sat May 8 07:06:14 1993 Richard Kenner (kenner@vlsi1.ultra.nyu.edu)

1327 * cp-typeck.c (default_conversion): Disable change of Apr 13th for
1328 now, since it seems to behave incorrectly in some cases.
1330 Fri May 7 17:38:22 1993 Michael Meissner (meissner@osf.org)
1332 * configure (all MIPS options): If --with-gnu-as is used, don't

1334 say we need collect2.
1335 (config.sub run): Explicitly invoke /bin/sh to run script, in case
1336 config.sub had it's execute bits turned off.
1338 * mips/t-mips-gas: New target file, used when the GNU assembler is
1339 used instead of the MIPS assembler.
1341 Fri May 7 17:41:00 1993 Richard Stallman (rms@mole.gnu.ai.mit.edu)
1343 * Makefile.in (float.h-nat): Use tmp-float.h as intermediate file.

1350 Fri May 7 13:15:40 1993 Jeffrey A. Law (law@snake.cs.utah.edu)
1352 * pa.h (reg_class): Add new NON_SHIFT_REGS class.
1353 (REG_CLASS_NAMES): Name new class "NON_SHIFT_REGS".

1359 Fri May 7 05:50:39 1993 Richard Kenner (kenner@vlsi1.ultra.nyu.edu)
1361 * reload.c (push_reload): Don't use IN as the reload reg in in-out
1362 reload if it is set elsewhere in the insn.
1364 Fri May 7 04:48:25 1993 Chris Smith (csmith@convex.com)
1366 * x-convex (CCLIBFLAGS): Build libgcc1 with -tm c1 so it can't
1367 cause executables to become c2-only.
1369 * xm-convex.h: Remove workarounds for OS 8.0 no longer needed.
1370 (bcopy, bzero): Define to use memcpy and memset, to get them inlined.
1372 * convex[123*].h (CC1_SPEC, CPP_SPEC, LIB_SPEC): Move to convex.h.
1374 * convex.h (TARGET_FLAGS): Add -mvolatile-[no]cache.
1375 (TARGET_FLAGS, LONG_TYPE_SIZE): add -mlong{32,64}.
1376 (target_cpu): Define, enumeration for targets to use instead of flags.
1377 (TARGET_C34, TARGET_C38): Add. These don't schedule the same as C2.
1378 (OVERRIDE_OPTIONS): Call init routine in convex.c.
1379 (CPP_SPEC, ASM_SPEC, LINK_SPEC): If originally bootstrapped with
1380 an ieee compiler, produce an ieee gcc.
1381 (LINK_LIBGCC_SPECIAL): Define, to avoid searching old libgcc.a
1382 versions during bootstrap.
1383 (STACK_BOUNDARY): Change from 32 to 64 -- odd-word aligned
1384 longwords are slow on c34.
1385 (FUNCTION_PROLOGUE): Make frame size a multiple of 8, not 4.
1386 (FUNCTION_EPILOGUE): Output a 0 to terminate c34 icache prefetch.
1387 (INITIAL_FRAME_POINTER_OFFSET): Make a multiple of 8.

1389 (HARD_REGNO_MODE_OK): Rewrite to make clearer.
1390 (MODES_TIEABLE_P): Rewrite to make clearer.
1391 (PREFERRED_RELOAD_CLASS): Rewrite to make clearer.
1392 (S0_REGNUM, A0_REGNUM): Define.
1393 (*_REGNUM): Write in terms of [AS]0_REGNUM instead of absolute numbers.
1394 (enum reg_class, etc): Add SI_REGS == S_REGS + INDEX_REGS.
1395 (REGNO_REG_CLASS, REG_CLASS_FROM_LETTER, REGNO_OK_FOR_*_P): Use tables.
1396 (CONST_OK_FOR_LETTER_P): Change. New def passes any const_int,
1397 rejects any const_double.
1398 (CONST_DOUBLE_OK_FOR_LETTER_P): Change. New defs are 'G' == low
1399 word all zeros, 'H' == high word all signs.
1400 (EXTRA_CONSTRAINT): New. 'Q' == volatile memref. Used to generate
1401 cache-bypass instructions when -mvolatile-nocache is set.
1402 (RETURN_POPS_ARGS): Change, always true.
1403 (FUNCTION_ARG_ADVANCE): Count args, not # words of args.
1404 (FUNCTION_ARG): Return arg count to the final VOIDmode FUNCTION_ARG
1405 hack that supplies "next arg register" to be stored in call insn.
1406 (TRAMPOLINE_TEMPLATE): Use instruction notation rather than constants.
1407 (INITIALIZE_TRAMPOLINE): Use gen_call_pop.
1408 (LEGITIMATE_CONSTANT_P): Rewrite to make clearer.
1409 (GO_IF_LEGITIMATE_ADDRESS): Do not use indirect addressing -- with
1410 insn scheduling, two loads can be faster and can't be slower.
1411 (SLOW_BYTE_ACCESS): Define unless C2. Memory access to bytes is
1412 not actually slow, but faster processors don't forward partial
1413 word writes to word reads, and setting SLOW_BYTE_ACCESS
1414 makes the code consistently use word ops where possible.
1415 (CONST_COSTS): Const_DOUBLE cost is zero -- if it appears, it is
1416 immediate and therefore free.
1417 (RTX_COSTS): areg+const is free (via indexing).
1418 (RTX_COSTS): Provide target-dependent values for *,<<,>>
1419 (ADDRESS_COST): Zero. Indirect addresses are no longer used.
1420 (ADJUST_COST): Define.
1421 (TARGET_FLOAT_FORMAT): Define as VAX_FLOAT_FORMAT. Also
1422 accurately describes the semantics (not the bit pattern)
1423 of convex ieee mode.
1424 (REAL_VALUE_ATOF): Define, to prevent real.c from constructing
1425 vax dfloats. Apparently it doesn't do gfloat.
1426 (CHECK_FLOAT_VALUE): Call convex.c.
1427 (ASM_FILE_START): Output appropriate .fpmode pseudo op.
1428 (ASM_IDENTIFY_GCC): Ouput a zero after gcc2_compiled to keep it
1429 from hiding the real name from profilers and adb.
1430 (ASM_OUTPUT_DOUBLE, _FLOAT): Use hex to avoid /bin/as conversion
1432 (ASM_DECLARE_FUNCTION_NAME): Define; call convex.c.
1433 (PRINT_OPERAND, _ADDRESS): Call convex.c.
1434 (EXIT_BODY): Define for libgcc2. Call atexit handler if present.
1436 convex.md: Add scheduling info.
1437 (movxx): One of the operands must be a register.
1438 (movdf, movdi): Add anonymous patterns that can load an arbitrary
1439 const_double by doing two immediate loads. This is not superior
1440 to loading it from memory, and can be worse, so LEGITIMATE_CONSTANT_P
1441 still rejects these constants, but the patterns are still useful
1442 so rtx folding can produce arbitrary results.
1443 (floatunsdidf, floatunsdisf): Add patterns that avoid double rounding.
1444 (floatunssidf, floatunssisf): Add patterns that mimic gcc's default
1445 method, to keep SI cvts from promoting to the above DI cvts.
1446 (fix_truncdfsi2): Use cvtd.l even if cvtd.w is available -- on c34
1447 cvtd.w is microcoded and slower.
1448 (addqi3, subqi3, mulqi3): can do immediate with word insn.
1449 (subsi3): use sub/neg to get reverse subtract (reduces reg shuffling).
1450 (udivsi3): give up on having sign_expand_binop do this; people keep
1451 breaking it. Manually extend unsigned SI to signed DI, then divide.
1452 (xshfxx3): The options rank differently on different machines, so
1453 spell them all out and enable the appropriate ones under TARGET_Cxx.
1454 (sqrtxx2): Put under flag_fast_math.
1455 (sinxx2, cosxx2): I don't know why these exist, but they do, so supply
1456 them. The other microcoded intrinsics are in convex math.h.
1457 (txtxx): Remove, no longer necessary.
1458 (cmpdi): Add alternative to fake "eq.l #0,sk" with "neg.l sk,scratch".
1459 (cmpqi): Omit, seems to produce marginally better cse than the old way.
1460 (cmpsf): Avoid compare against 0.0 in ieee mode, since -0.0 is
1461 possible and would confuse old ucode.
1463 (anon): Add patterns to pick up on dbra optimizations and implement the
1464 sub/test part. (This optimizes out the compare against 0.)
1465 (call, call_value): Use _pop form instead, and let convex.c replace
1466 the pushes with fp stores.
1467 (end): Put local variable list back.
1469 convex.c (init_convex): New. Fill in tables used by convex.h.
1470 (psw_disable_float): New. Turn off float exception enables to
1471 make the environment more ieee-like.

7283 %r1 as a secondary reload register.
7284 (emit_move_sequence, SYMBOL_REF case): If TARGET_KERNEL, then handle
7285 secondary reload created for a symbolic (high (const (plus ...))).
7286 No longer show DP relocation; read_only and normal operands emit the
7288 Emit the same RTL before and after reload, only change how the
7289 scratch/temporary register is chosen.
7291 Sun Jan 10 11:42:12 1993 Richard Kenner (kenner@vlsi1.ultra.nyu.edu)
7293 * combine.c (make_extraction): Don't use POS < 0 as a flag
7294 that POS_RTX is to be used; instead use POS_RTX unless it is
7295 nonzero. If POS_RTX is a constant, set POS and clear POS_RTX.
7296 (make_compound_operation, make_field_assignment): Pass 0 for POS
7297 instead of -1 when POS_RTX is nonzero.
7299 Sat Jan 9 01:34:27 1993 Richard Stallman (rms@mole.gnu.ai.mit.edu)
7301 * reload1.c (reload_as_needed): Test for whether to call

7320 not unsigned_char_..., as index type for ..._array_type_node.
7322 * toplev.c (really_sorry): Use progname in error message, not c++.
7324 * optabs.c (expand_binop): For complex mult, compute res

7354 Wed Jan 6 17:43:23 1993 Brendan Kehoe (brendan@lisa.cygnus.com)
7356 * cp-decl.c (init_decl_processing): Make flag_no_builtin avoid
7357 definitions of builtin fns memcpy, memcmp, strcmp, strcpy, strlen,
7358 sin, and cos. (Add sin and cos.)

7361 * cp-decl.c (current_local_enum): New variable.
7362 (start_enum): Set TREE_ADDRESSABLE on the tag here, and clear
7364 (build_enumerator): Build the field decl here, rather than in
7365 grok_enum_decls; set its TREE_CHAIN to the current_local_enum.
7366 (grok_enum_decls): Chain down, setting the type.
7368 Tue Jan 5 22:09:18 1993 Brendan Kehoe (brendan@lisa.cygnus.com)

7383 Jan 5 14:09:08 1993 Paul Eggert (eggert@twinsun.com)
7385 * cp-lex.c (): Propagate a change from c-lex.c.
7387 Tue Jan 5 13:27:05 1993 Mike Stump (mrs@cygnus.com)
7389 Sep 14 17:48:27 1992 Paul Eggert (eggert@twinsun.com)
7391 * cp-lex.c (real_yylex): For floats, use REAL_VALUES_LESS to
7392 distinguish underflow from overflow. Delete special case for 0.0.

7402 from c-convert.c and cp-cvt.c (such as convert_to_integer).
7403 * convert.h: New file: declarations exported from convert.c.
7404 * c-convert.c, cp-cvt.c: Correspondingly reduced.
7405 * cp-cvt.c (cp_convert_to_pointer): New function, with the
7406 extra hair beyond that provided by the C convert_to_pointer.
7407 * Makefile.in (OBJS): Add convert.o.
7408 * cp-typeck.c (build_binary_op), cp-tree.h: Add extra convert_p
7409 parameter, for consistency with the C version (so we can make
7410 convert_to_integer independent of C or C++).
7411 * cp-cvt.c, cp-decl.c, cp-decl2.c, cp-except.c, cp-init.c,
7412 cp-typeck.c, cp-parse.y: Fix calls to build_binary_op to pass
7413 the new convert_p parameter (i.e. 1).
7415 Fri Dec 18 19:19:28 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7417 * cp-method.c (build_overload_nested_name): Use DECL_NAME instead of
7418 DECL_ASSEMBLER_NAME, since pushtag now mangles together
7419 DECL_ASSEMBLER_NAME. This will make us emit `Q21D1B', not `Q221D1B'.
7421 * cp-decl2.c (grokclassfn): Try using the local value for a nested
7422 type if the IDENTIFIER_TYPE_VALUE isn't there.
7424 Wed Dec 16 18:18:43 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7426 * cp-typeck.c (build_unary_op): Set TREE_CONSTANT on the address of
7427 a function if it's static or external (i.e., staticp likes it).
7429 Wed Dec 16 16:09:37 1992 Mike Stump (mrs@cygnus.com)
7431 * cp-decl.c (sigsegv, init_decl_processing): Give users the line
7432 number and source filename on code that makes the back-end call
7435 Tue Dec 15 16:50:45 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7437 * cp-tree.h (CLASSTYPE_NAMES): Deleted.
7439 * cp-init.c (build_offset_ref): When getting ready to give an error
7440 about something not being a member or operator, only call
7441 operator_name_string when it is indeed an operator.
7443 * cp-decl2.c (bad_specifiers): New function.
7444 * cp-tree.h (bad_specifiers): Add prototype.
7445 * cp-decl.c (grokdeclarator): Use it in places where we had

7450 * cp-lex.c (UNSET_RESERVED_WORD): Update from c-lex.c.
7452 Tue Dec 15 01:21:44 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7454 * cp-lex.c (real_yylex): Convert invisible initialized char array
7455 vars to string constants.
7457 Mon Dec 14 11:38:10 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7459 * Makefile.in: Fix a lot of dependencies on cp-lex.h and other
7460 headers for cp-*.o targets.
7462 * cp-search.c (get_first_matching_virtual): Use warning_with_decl,
7463 not error_with_decl, inside code that's only ever reached with
7464 -Woverloaded-virtual.
7466 * cp-typeck.c (c_expand_return): When building the INIT_EXPR, clear
7467 out the context if it's an ERROR_MARK so the back-end won't die later.
7469 * cp-type2.c (my_friendly_abort): Don't say anything like "please
7470 fix above errors", just exit quietly.
7472 * cp-lex.h (enum rid): Reordered for improved speed in grokdeclarator
7473 when it does its linear search. RID_WCHAR is no longer in the
7474 search path, since it's found by hand (as are RID_INT and RID_CHAR).
7475 (RID_FIRST_MODIFIER): Start at RID_EXTERN now.
7477 * cp-parse.y (overloaddef): Warn that using `overload' is an
7480 Wed Dec 9 08:27:13 1992 Niklas Hallqvist (niklas at della.appli.se)
7482 * cp-decl.c (init_decl_processing): Make sure the "unknown type"
7483 typedecl gets ignored by the debuginfo generators.
7485 Sun Dec 13 02:38:43 1992 Brendan Kehoe (brendan@cygnus.com)
7487 * cp-search.c (lookup_nested_field): Check for assignment to members
7488 of an enclosing class only when looking at a member, not at other
7489 things (like nested types).
7491 * cp-pt.c (type_unification): Only check that ARGS is a TREE_LIST if
7494 These four are from Niklas Hallqvist:
7496 * cp-search.c (compute_visibility): Use the main variant when
7497 testing if a member function belongs in the current class.
7499 * cp-call.c (build_method_call): Don't look for constructors
7500 called by initialization inside class methods in the classes'
7501 bases (as opposed to inherited methods).
7503 * cp-typeck.c (convert_for_initialization): In the case of
7504 templates, make sure build_method_call knows which instantiation
7505 of the class template we're initializing an object of.
7507 * cp-decl.c (grokdeclarator): Instead of an assert, return a
7508 NULL_TREE if the return_type's not return_ctor.
7510 Sat Dec 12 23:52:25 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7512 * cp-dem.c (cplus_demangle): Recognize 'S' for signed char.
7513 (do_cuv_prefix): Print out "signed" for it.
7515 Fri Dec 11 19:36:36 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7517 * cp-cvt.c (convert_to_reference): Fix a typo about when to return

7520 Tue Dec 8 20:05:25 1992 Mike Stump (mrs@cygnus.com)
7522 * cp-cvt.c (convert_to_reference): If a conversion can be found via
7523 a constructor, then use it.
7525 Fri Dec 4 13:53:01 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7527 * cp-lex.c (init_lex): Delete inits for CARD_EXPR and SET_LE_EXPR,
7528 since we never actually use them.
7530 Thu Dec 3 19:20:14 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7532 * cp-decl.c: Include sys/types.h for systems that need things for
7535 Wed Dec 2 15:51:34 1992 Mike Stump (mrs@cygnus.com)
7537 * cp-call.c (build_method_call): Don't call abort for pure virtual
7538 methods, instead, call the user-defined method. Addresses of pure
7539 virtual methods are probably still wrong.
7541 Wed Dec 2 14:44:41 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7543 * cp-call.c (convert_harshness): If parm's null for a reference (as
7544 can be passed in), return 0.
7546 Tue Dec 1 18:05:20 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7548 * cp-decl.c (grokdeclarator): Make member initialization be a
7549 warning, not an error. Only issue it if not -pedantic, since
7550 grokfield will issue an error when pedantic. Only warn about
7551 constant members being initialized if `-ansi' is being used.
7552 (finish_decl): Only complain about uninitialized const's that aren't
7553 members when acting -pedantic, since we'll have already issued the
7554 error about initializing a field.
7556 * cp-type2.c (build_functional_cast): Revert change of Nov 2,
7557 concerning clearing the TREE_VALUE of a default parameter.
7559 Tue Dec 1 11:09:50 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
7561 * cp-call.c (build_method_call): When looking for a default arg
7562 initialized by a ctor, be careful of a null ref w/ operand 1.
7564 * cp-method.c (icat): Handle an argument of `1' first, since it's
7565 the most common case.
7567 Tue Dec 1 02:36:28 1992 Mike Stump (mrs@cygnus.com)
7569 * cp-search.c (get_first_matching_virtual): Only set the
7570 DECL_CONTEXT if the new context is a an unambiguous parent of the
7573 Tue Dec 1 02:20:32 1992 Mike Stump (mrs@cygnus.com)
7575 Wed Nov 25 18:25:06 1992 Jim Wilson (wilson@sphagnum.cygnus.com)

7584 Thu Nov 26 11:22:12 1992 Mike Stump (mrs@cygnus.com)
7586 * c++: Put a newline after for arg and before do, as ``for arg do''
7587 is not accepted by all shells.
7589 Mon Nov 23 13:21:43 1992 Brendan Kehoe (brendan@cygnus.com)
7591 * c++ (-lm): Also recognize -lmath as a math library.
7593 * c++ (first): Only shift if $first is no, on the chance we got no
7594 arguments at all. If we didn't get anything, say so (since -lg++
7595 will fake out the gcc driver into thinking we want to do something).
7597 * cp-parse.y (paren_expr_or_null): New rule to emit an error when an
7598 empty condition is used when it shouldn't.
7599 (simple_if, stmt): Use it for `if', `while', and `do'.
7601 * cp-decl.c (start_decl): If grokdeclarator returns a
7602 void_type_node, return a NULL_TREE.
7604 * cp-typeck.c (build_modify_expr_1): When calling build_opfncall for
7605 `operator=', use make_node to create a plain NOP_EXPR for it to use,
7606 rather than trying to pass NOP_EXPR down hoping it gets there intact.
7607 (build_modify_expr): Ditto.
7608 * cp-method.c (build_opfncall): Use TREE_CODE on ARG3 for a
7609 MODIFY_EXPR, since it'll be coming in properly as a tree now.
7611 Sat Nov 21 02:33:28 1992 Brendan Kehoe (brendan@cygnus.com)
7613 * cp-init.c (expand_default_init): Clear DECL_REGISTER if we're
7614 going to call a ctor, otherwise we may end up generating bogus and
7615 confusing error messages about taking the addr of something declared
7618 * cp-typeck.c (build_x_function_call): Recognize a ptr-to-method
7619 that is being passed in as a function argument or as part of
7621 (build_indirect_ref): If ERRORSTRING is NULL (it's passed in that
7622 way in many places), then don't try to use it.
7624 Sat Nov 21 01:49:34 1992 Brendan Kehoe (brendan@cygnus.com)
7626 Work towards 64-bit support, and still more housecleaning.
7628 * cp-*.[cy]: For all functions and variables, pass/initialize/compare
7629 NULL_TREE, not 0, where appropriate. Cast comparisons against 0
7630 with the proper pointer types, where appropriate. Fix all passing

7660 revert_static_member_fn): Declare static fns w/ prototypes.
7661 (pushlevel): Cast passing of NEWLEVEL to an int.
7662 (poplevel, poplevel_class, finish_method): Cast first two args of

7673 never used. Change all callers.
7674 * cp-dem.c (cplus_demangle): Delete unused var non_empty.
7675 (NULL): Undef first.
7676 * cp-except.c: (call_to_unhandled_exception): Add decl of

7690 * cp-parse.y (unary_expr): Cast first arg to build_x_unary_op to
7691 be of enum tree_code type. For every call to build_new, pass its
7692 fourth arg as a comparison of $$ against NULL_TREE, instead of
7694 (combine_strings, truthvalue_conversion): Add extern decls.
7695 (structsp): Pass lookup_name its missing second arg (0).
7696 (component_decl): Pass 5, not 6, args to grokfield.
7697 (ansi_except_stmts): Delete decls of ansi_expand_start_match and

8639 * reload.c (push_reload): Move the NO_REGS abort after the
8640 error check for asms, to avoid crashing for asms.

8875 (save_restore): Merge function into save_restore_insns.
8876 (save_restore_insns): Add FILE * argument, to write to the .s
8877 file if non-NULL -- otherwise produce insns. Add arguments to
8878 pass in that the prologue/epilogue has loaded the stack size into

8880 support, so that it doesn't abort if large stack frame, saved GP
8881 registers, and no saved FP registers. If large stack frame, use
8882 stack size stored in $8 if we can.

9302 * c++ (first): Only shift if $first is no, on the chance we got no

9307 void_type_node, return a NULL_TREE.
9309 * cp-typeck.c (build_modify_expr_1): When calling build_opfncall for

9319 * cp-init.c (expand_default_init): Clear DECL_REGISTER if we're

9325 that is being passed in as a function argument or as part of
9327 (build_indirect_ref): If ERRORSTRING is NULL (it's passed in that
