898:
899: * mips.md (extend*): Use gen_lowpart to make the SUBREG, rather than
900: doing it wrong by hand. If not optimizing, make sign extends from

921: (assemble_integer, assemble_real): New functions.
922: (output_constant_pool, output_constant): Use new functions.
923: * final.c (end_final, profile_function): Likewise.
924:

942: * objc-actions.c (build_module_descriptor): Emit a constructor
943: function. Constructor function calls a ObjC run-time routine passing

945: (init_objc): Call different constructor function if not Next.
946: (build_selector_translation_table): Don't give a selector global scope.
947: Changed in construction of decl_specs.
948:
949: Tue Dec 31 18:06:23 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)

965:
966: * mips.md (extend*): Replace sign extension insns with a
967: define_expand that converts the expansion into the appropriate
968: shifts. Add insns that do sign extension from memory, which the
969: optimizer will utilitize if the thing being sign extended really
970: comes from memory. This allows the shifts to compete for CSE, at a
971: potential cost of generating worse code if reload spills a HI or QI
972: register to the stack.
973: (sne define_split): Instead of using a constant 0 as the second
974: argument to the slti instruction, use a hard coded regisiter 0.
975:
976: * mips-sysv.h (MD_STARTFILE_PREFIX): Define to point into the
977: directory where the MIPS compilers live.
978: (LIB_SPEC): Add crtn.o after all libs.

987:
988: * t-decrose, t-decstatn, t-encrose, t-i386rose, t-mips: Remove
989: collect2 from EXTRA_PASSES, as collect2 does not need installing as
990: collect2. Also, change the symlink back to a hard link.
991:
992: * Makefile.in: Add collect2 to STAGESTUFF as it is something that
993: needs removing or moving to stagen, but it should not be installed.

996:

998: the lattern can use the result of the former.
999:
1000: * conditions.h: In comments, refer to `tm.h', since `tm-' is no
1001: longer the form used for these files.
1002:

1015: * conv1*.h, conv2*.h: Files deleted.
1016:
1017: * m68k.h, fx80.h (WCHAR_TYPE, WCHAR_TYPE_SIZE): Defined.

1025:
1026: * i386.md (mulhi3,mulsi3): If a multiply by constant 128, use the
1027: two operand multiply instead of three operand form: the AT&T
1028: assemblers generate incorrect object code for the latter.

1033:
1034: * reload1.c (emit_reload_insns): Check if reload_in needs a secondary
1035: reload if we have an in-out reload, since it might have been the

1037:
1038: * cse.c (simplify_unary_operation): Mode of integer CONST_DOUBLE is
1039: VOIDmode, not DImode.
1040:
1041: * fold-const.c (fold, case COND_EXPR): Make an ABS_EXPR when the
1042: comparison is LE_EXPR or LT_EXPR.
1043:
1044: * calls.c (calls_alloca): New function.
1045: (expand_call): Preexpand any argument that contains a call to alloca

1069: All callers changed.
1070:

1152:
1153: * dbxout.c (dbxout_type): Tiemann's DECL_IGNORED_P optimization (Nov
1154: 20) was a little too drastic: If it succeded, no type info was

1156: Instead, just set 'full=0',
1157: * dbxout.c (dbxout_symbol): Re-write code for TYPE_DECL to be a
1158: little cleaner. It *seems* to work ...

1188: insns immediately preceeding it.

1227: is a scratch register for those loads that need it.
1228: (emit_move_sequence): New argument SCRATCH_REG, which is a scratch
1229: register for those loads that need it. When loading a pic label,
1230: set %o7 instead of clobbering it so its value can be used later.

1232: register window in frame if size greater than 0.

1241: * sparc.md: Fix all callers of legitimize_pic_address and

1250: pattern when pic.
1251: (pic_tablejump): Explicitly mention in rtl that %o7 is used,
1252: instead of using %^.

1255: BLOCK_PROFILER_USED_REG_P macro.

1902:
1903: * mips.md (fix_trunc*): Reorder constraints so that 'd' comes before
1904: 'f', and put a '*' in front of 'f' constraints to keep integer in

2587: (pushdecl_top_level): if class_binding_level is set, search from it
2588: instead of only from current_binding_level when trying to find
2589: shadowed values. This is in support of tests m5.cc through m8.cc,
2590: which broke after the changes for m9.cc were installed.
2591:
2592: * cp-spew.c (do_aggr): New function. Looks ahead from AGGR to see if
2593: we have AGGR identifier { or AGGR identifier : which are both
2594: definitions, and passes up identifier_DEFN instead. This is in

2635: * gbl-ctors.h (DO_GLOBAL_CTORS_BODY): Don't reference ON_EXIT for
2636: those poor systems without atexit or on_exit.

2638: Wed Dec 11 09:06:52 1991 Jeffrey A. Law (law at wombat.gnu.ai.mit.edu)
2639:
2640: * m68k.c (output_function_prologue, output_function_epilogue):
2641: When saving/restoring only 2 registers, do so with two "movel"

2643: faster code for the 68020 and later machines.
2644:
2645: Wed Dec 11 06:45:08 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)

2678:
2679: * Makefile.in (collect2, collect2.o): Change to use the default
2680: compiler to build collect2, instead of the newly built GCC, since
2681: otherwise, collect2 will create a circular dependency. Also, pass
2682: LDFLAGS when linking.
2683:
2684: * collect-osf.c (write_s_file): Change to the new way of doing
2685: constructors and destructors of having an end marker instead of a
2686: count.
2687:
2688: * collect.c (REAL_AS_PATH, REAL_LD_PATH, REAL_NM_PATH): New macros
2689: to allow cross compilers to specify where the real linker,

2691: (NM_FLAGS): New macro to allow a configuration to change what flags
2692: get passed to nm.
2693: (alloca defines): Remove alloca defines, since config.h provides
2694: them.
2695: (write_hooks): Change to the new way of doing constructors and
2696: destructors of having an end marker instead of a count. Cast all
2697: alloca calls to be the appropriate pointer type. Put both
2698: constructors and destructors into the data section, because the MIPS
2699: tools do not like non-instructions in the .text section.
2700:
2701: * decrose.h (HAVE_ATEXIT): Define, OSF/1 has atexit.
2702: (FULL_PROTOTYPES, NO_CONST_IN_SYSCALL): Remove, no longer used.

2713: needed, since constructor/destructor support moved into gnulib2.c.
2714:
2715: * t-i386rose (LIB2FUNCS_EXTRA): Remove, osf-main.c is no longer
2716: needed, since constructor/destructor support moved into gnulib2.c.
2717:
2718: * t-decstatn (CCLIBFLAGS, GNULIB2_CFLAGS): Define so that gnulib1
2719: and gnulib2 are both compiled with -G 0, in case the users compiles
2720: and links this way. It also fixes a bug where the constructors and
2721: destructors that collect2 produces are in the big data section, but
2722: gnulib2 thinks they are in the small data section, because it only
2723: sees a pointer.
2724: (ld): Add -f to remove old ld link to collect2, if it exists.
2725:
2726: * t-mips (CCLIBFLAGS, GNULIB2_CFLAGS): Define so that gnulib1
2727: and gnulib2 are both compiled with -G 0, in case the users compiles
2728: and links this way. It also fixes a bug where the constructors and
2729: destructors that collect2 produces are in the big data section, but
2730: gnulib2 thinks they are in the small data section, because it only
2731: sees a pointer.
2732: (ld): Add rule to link collect2 to ld.
2733: (EXTRA_PASSES): Build collect2 (aka ld).
2734:
2735: * xm-mips.h (alloca): If not GNU C, declare alloca to be char *.
2736:
2737: * mips-tfile.c (add_aux_sym_tir): Move code to record bitfield size,
2738: so that it agrees with MIPS ECOFF practice, rather than the
2739: documentation, which affects enum bitfields. Changes from Per
2740: Bothner.
2741:
2742: Tue Dec 10 14:10:10 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)

2815: pointer-to-method as well. Don't build an OFFSET_REF for any
2816: "function" that already has pointer type. Only use
2817: DECL_CLASS_CONTEXT to find type of `this' for FUNCTION_DECLs; for
2818: method pointer expressions, look up the basetype of the method type.

3888: If the next instruction is a label, put nops before label, not
3889: after. Add support for mflo/mfhi, which need 2 nops if the next
3890: instruction would modify the hi/lo registers.
3891: (mips_move_1word, mips_move_2words): mips_fill_delay_slot calling

3912: two nops needed for the mflo instruction. Don't allow an integer

3924: the intermediate parts of the compilation. Reported by

3927: define_expand for subsi3.

3929: define_expand for norsi3.
3930: (andsi3, iorsi3, xorsi3): Be more liberal than the real machine, and
3931: allow 32 bit constants to improve the code generated for bitfields,
3932: at the expense of potentially not moving the constant out of loops.
3933: (various): Add = constraint to all clobbers.
3934: (fix_trunc*): Go back to old method of using two clobbers, since
3935: unoptimized compiles call abort otherwise, when returning the result

3939: delay slots.

3941: to check for needing nops. Used by multiply/divide to schedule
3942: the two nops needed after mfhi/mflo if the next instruction would
3943: clobber the register.
3944: (CONDITIONAL_REGISTER_USAGE): If -msoft-float, disable all FP
3945: registers.

3947: patterns, in case the code is wrong.
3948: (HARD_REGNO_NREGS): All FP registers use register pairs, so that
3949: SF in a GP register takes only one register, and SI in a FP
3950: register takes 2.
3951: (HARD_REGNO_MODE_OK): Change macro to reference the array
3952: mips_hard_regno_mode_ok, which is now built in override_options.
3953: (CONST_OK_FOR_LETTER_P): 'N' is now for negative numbers, 'O' is
3954: an exact power of 2, and 'P' is now for positive numbers.
3955: (PREFERRED_RELOAD_CLASS): If -msoft-float, never prefer a FP
3956: register.
3957: (PREFERRED_RELOAD_CLASS_FM): Delete, since nobody uses it.
3958: (FINAL_PRESCAN_INSN): Check for mips_load_reg3 and mips_load_reg4
3959: being mentioned. Also add a missing tab when more than one delay
3960: slot.
3961: (CONST_COSTS): Make all constant ints cost 0 to lower register
3962: pressure according to Richard Kenner.
3963: (RTX_COSTS): Adjust costs for DI, SF, and DF modes, and add ABS/FFS
3964: costs as well.
3965: (REGISTER_MOVE_COSTS): Bump costs for moving between register
3966: classes, so that reload doesn't try to store int type values in the
3967: floating point registers.

4487: is < 0. Definitely see TYPENAME if LOOKING_FOR_TYPENAME > 0.
4488:
4489: * cp-decl.c (grokdeclarator): Any type construction that uses a
4490: struct/union/enum type that is not yet defines pushes that type into
4491: the global namespace.
4492:
4493: * cp-spew.c (discard_token): Renamed from `eat_token'.
4494: Also, make all local functions static. Some day we'll use inlining.

4502: (yyprint): Took out case for TYPENAME_SCOPE.
4503:
4504: * cp-lex.c (real_yylex): renamed from yylex. Also all of the code
4505: dealing with nested classes has been #if 0'd in favor of the code in
4506: cp-spew.c.
4507:
4508: * cp-spew.c (New File): This calls yylex (which is now real_yylex)
4509: and looks ahead as far as possible to bind up nested classes and
4510: pass them on to the parser.
4511:
4512: Thu Nov 21 18:14:11 1991 Jim Wilson (wilson at wookumz.gnu.ai.mit.edu)

4538: (option header): Mention that -W options take the no- prefix as well
4539: as -f options.

4553:
4554: * real.h (REAL_VALUE_TRUNCATE): Default is to truncate to float if
4555: mode size is BITS_PER_WORD instead of when mode if SFmode.

4573: correct.
4574: (lookup_tag): Bypass redefinition error message for UPT as well as
4575: for TEMPLATE_DECL.
4576: (start_decl): Add template decls only to top level. Print message
4577: for non-function, non-class templates.
4578: (finish_decl): Disable code that renames anonymous types; leave it
4579: disabled until we figure out why it was being done in the first
4580: place.
4581: (grokdeclarator): Eliminate hack to deal with destructor templates.
4582: Extend some code handling constructors to handle destructors as

4599: nodes, instead of crashing.
4600: (fndecl_as_string): For constructor and destructor, use name of
4601: function rather than looking up class constructor name; should be
4602: the same, and it's cheaper this way.
4603: (build_overload_name): Make template-related names unique, as well
4604: as unlikely to be accepted by the assembler.
4605:
4606: * cp-parse.y (yyprint): Handle PRE_PARSED_CLASS_DECL.
4607: (template_def): In case handling destructors, pass new decl to
4608: end_template_decl, rather than ungrokked call_expr node. Rewrote

4614:
4615: * cp-pt.c: New comment at start lists some known problems.

4640: register. Rewrite REG_DEAD note code to use the new scheme (see
4641: the Nov 1 ChangeLog entry).

4643: already has one.

4652: to also be consistent with the -fno- options.
4653: * objc-actions.c: Add a -Wno-selector option to match the
4654: -Wselector option.
4655:
4656: * gcc.c (default_compilers): Pass all -W options to cpp, so that
4657: -Wno options will be passed along with the -W options that it
4658: understands.

4710: combine can convert FP hard registers to SImode.

4748: away only cleanup generated by 'build_functional_cast'.
4749:
4750: * cp-init.c (build_new): Use TRUE_TYPE instead of TYPE more
4751: consistently, in case TYPE is really an ARRAY_TYPE on its own.
4752:

4818:
4819: * c-typeck.c (build_binary_op_nodefault): Delete ERROR_CODE
4820: argument because it is always the same as CODE. Add new argument
4821: CONVERT_P, and call default_conversion on the operand trees if
4822: true. Rename to build_binary_op.
4823: (old build_binary_op): Deleted because it is now unnecessary.
4824: * c-common.c, c-convert.c, c-decl.c, c-tree.h, c-typeck.c: All
4825: callers and other references to build_binary_op* fixed.
4826: * c-typeck.c (new build_binary_op): Add warning message for
4827: comparisons of signed and unsigned variables that won't give the
4828: expected result due to unexpected sign extension.

4838: * collect2.c: Define vfork as fork for USG. Rewrite to not use
4839: prototypes, so it doesn't need gcc for compilation.
4840: (main): No longer uses static sized array for ld arguments, so
4841: that long command lines will work. Vfork ld instead of running
4842: via popen with nm.

4865: for some configurations that obviously have not been tested in a
4866: while.
4867:
4868: * config.subr: Massive overhaul. It claimed to canonicalize
4869: the machine specification, but it never really did. Now it
4870: does. In general, it is not necessary to specify the os for
4871: popular machines that have a popular os, or given the os, it
4872: can sometimes figure out the vendor. Added in all the old
4873: ways of specifying machines from configure. Also added
4874: support for all (before it was missing a few) of the tm-*.h
4875: files. It now supports the concept of guessing the vendor for
4876: a given CPU type. It now supports the concept of guessing the
4877: os version given the vendor and/or the CPU type. Changed the
4878: default os for vax to ultrix, changed the default os for i386
4879: to sco.
4880:
4881: * collect-ld: New file. It is useful when compiling C++ programs

4967:
4968: * mips-tfile.c (all): Change small allocation requests to use
4969: separate allocation and free functions, instead of using the word8

5019: We get better code without them.
5020: (indirect_jump, tablejump): Extend indirect_jump pattern to accept

5091: line moves, have two outstanding loads before a store, for newer
5092: machines that want two delay slots.

5094: loop, for a loop that moves 16 bytes in 11 cycles if aligned, and 16
5095: bytes in 19 cycles if not aligned.
5096: (block_move_memcpy): Change argument names for consistancy.
5097: (expand_block_move): Always move address into a register, even for
5098: one byte moves. Fix bugs in calling memcpy. If moving a large
5099: constant amount of unaligned data, emit a runtime check to see if

5101: an unaligned move loop.
5102:
5103: * mips-tfile.c (toplevel): Make some changes, so that mips-tfile can
5104: be debugged on OSF/1.

5181: * cp-tree.h: Declare flag_ansi_exceptions.
5182: * gplus.gperf: Add 'throw' (for ANSI exception handling),
5183: and update private/protected/public from (old) cp-lex.c.
5184: * cp-hash.h: New file, generated from gplus.gperf.
5185: * cp-lex.c: #include cp-hash.h, instead of requiring
5186: manual cut-and-paste when keywords are changed.

5189: Hooks for ANSI-style exception handling.
5190: * cp-parse.y: Parse ANSI-style exception stuff.
5191: * cp-decl2.c: Define new flag flag_ansi_exceptions.

5207: * cp-class.c (add_virtual_function, finish_struct): Do not
5208: create a vtable just because of -fdossier.
5209: * cp-gc.c: Each type points to an array of fields,

5212: unneded extra indirection. Also other tweaks to save space.
5213: * cp-decl.c (init_decl_processing): Add length of
5214: field and method arrays to descriptors, instead of
5215: relying on NULL-termination (since we no longer have

5218: method descriptors be shorts.
5219: * cp-method.c: Remove no-longer-needed functions

5381: the current obstack is permanent.
5382:
5383: * cp-parse.y (template_def): Delete derivations that were
5384: purportedly for constructors; they didn't work.
5385: (notype_declarator): Deal with them here.
5386: (template_instantiate_once): Copy decl node with permanent obstacks,

5533: (gnulib1): Don't copy gnulib1.c into a temporary .c file before

5626: if none of the words are needed.
5627: (libcall_dead_p): Allow CALL to be in any part of PARALLEL.
5628: Use insn_dead_p to see if SET of return register is dead; old code
5629: incorrectly tested multi-word registers.
5630: (mark_set_1): Track whether all or only some words of a value are
5631: needed; write partial REG_UNUSED note if only some words won't be

5658: artificial #define lines for builtin symbols.
5659: Call `output_line_directive' before doing each make_define or

5672: do_undef do output to stdout.
5673: Call do_undef with a real output buffer.

5802: permanent obstack storage.
5803: (start_decl): While processing_template_decl, don't also need to

6376: define it to be 1.
6377: (build_overload_name): Test to see if it's nonzero, rather than
6378: whether it's defined; this permits compilation options to disable
6379: it, but leave it enabled by default. Add one to the array size,
6380: since the value retrieved appears to be the maximum index, not the
6381: true array size.
6382:
6383: Thu Oct 17 19:15:37 1991 Mark Eichin (eichin at tweedledumber.cygnus.com)
6384:
6385: * cp-pt.c (instantiate_class_template): has an argument to
6386: indicate whether to setup for parsing or not. (All existing cases
6387: did a feed input, but if we are trying to set up intermediate nodes
6388: while waiting for the parser to return to a template_instantiate
6389: site we need to suppress the parsing part of it, which will get
6390: redone later.)
6391: (tsubst): under case UNINSTANTIATED_P_TYPE, actually instantiate any
6392: class templates that are needed for function return values, and set
6393: them up as pending templates to be run later.
6394:
6395: * cp-parse.y (primary): since build_x_function_call doesn't
6396: require a complete type any more in certain cases, we instantiate
6397: any pending templates and then require_complete_type on the
6398: remainder.
6399:
6400: * cp-typeck.c (build_function_call_real): added an argument to
6401: optionally skip the require_complete_type... implicit template
6402: instantiation has to be postponed, so we won't get a complete type
6403: until the parser can grab it.
6404:
6405: * cp-call.c (build_overload_call_real): added an argument do
6406: allow choice of build_function_call_maybe or build_function_call
6407: based on whether we thought we would require a complete type out of
6408: build_function_call.

6421: * cp-call.c (build_overload_call): If template match fails, still
6422: set function field of candidate structure, and set bad_arg field to
6423: new magic number -4 to indicate failed type unificiation.
6424:
6425: * cp-class.c (add_method): Call make_function_rtl only if not
6426: processing a template declaration.
6427:

6430: Looks like a type node.
6431:
6432: * cp-decl.c (struct binding_level): New flag indicating any name
6433: should be accepted when looked up at this level. This is a kludge
6434: to try to deal with methods of parameterized types.
6435: (declare_uninstantiated_type_level): Set it.
6436: (uninstantiated_type_level_p): Return it.
6437: * cp-class.c (pushclass): If the "class" type is

6444: (dont_forget_overload): Deleted.
6445: (push_overloaded_decl_1): New fn; like push_overloaded_decl, but

6447: (auto_function): Use it.
6448:
6449: * cp-decl.c (print_binding_level): Print type-shadowed field at
6450: each level. Skip fields with no values.
6451:
6452: * cp-decl.c (adjust_type_value): Use SET_IDENTIFIER_TYPE_VALUE,
6453: not set_identifier_type_value.
6454:

6459: levels, munging outermost one if found to cause it to "restore" the
6460: new global value.
6461:
6462: * cp-decl.c (push_overloaded_decl): Don't punt second or later
6463: templates of a given name.
6464:
6465: * cp-decl.c (start_decl): Template-handling code moved up, to
6466: cope better with variable declarations. Don't check for incomplete
6467: type or constructor requirements when processing template.
6468:
6469: * cp-decl2.c (build_push_scope): If passed error mark node, just
6470: return it.

6478: (build_overload_name, case UNINSTANTIATED_P_TYPE): Handle like other
6479: template-related types that shouldn't get visibility outside the
6480: compiler.
6481:
6482: * cp-parse.y (template_type): Use IDENTIFIER_TYPE_VALUE from
6483: name, if expansion doesn't happen.
6484: (tmpl.1, tmpl.2): Now type <ttype>. Value is null or return value
6485: from instantiate_class_template.
6486: (template_instantiation): Always put copy of decl in global scope.
6487: Use pushdecl_top_level instead of setting IDENTIFIER_GLOBAL_VALUE
6488: slot.

8739:
8740: * cse.c (cse_insn): Fix arg in insert_regs call when making a

8755: When looking for associative operation, call fold_rtx on potential
8756: constant as well as equiv_constant.
8757: (equiv_constant): Just look up a constant quantity for a register;

9016: functions where there's a collision.

9021: slot for global definitions that are not in IDENTIFIER_GLOBAL_VAL.

9287:
9288: * All cplus-* files: Change the representation of the C++
9289: inheritance lattice for types. There is no longer such a thing as a

9291: accessed via their CLASSTYPE_ASSOC field.
9292:
9293: * cplus-tree.h (lang_type): Delete fields OFFSET,
9294: MAIN_CLASS_VARIANT, NEXT_CLASS_VARIANT, VIA_PUB_OR_VIRT.

9305: sneaking it into the TREE_TYPE field of the basetypes.
9306:
9307: (ASSOC_TYPE): Deleted. Now use ASSOC_VALUE everywhere.
9308: (ASSOC_{BASETYPE,BASETYPES}): New macros. Both are operations on
9309: assocs and return assocs.
9310: (CLASS_ASSOC_BASETYPE): New macro. This performs roughly the same
9311: function that CLASSTYPE_BASECLASS used to, but it retains no assoc
9312: info in the type it returns.
9313: (ASSOC_NEXT_ASSOC): New macro used for traversing assoc chains built
9314: up by search routines.
9315: (ASSOC_VIA_{PUBLIC,VIRTUAL}): New macros for accessing inheritance

9324: relationships (get_base_type and get_base_distance) to use this macro.
9325:

9911: * genemit.c (gen_expand, main): Change FAIL macro to be a simple
9912: goto _fail, and initialize the return value to 0 in the prologue.

9933: * cplus-except.c (cplus_expand_start_except): Set up variables
9934: `current_exception_name_as_rtx' and `current_exception_parms_as_rtx'.
9935: These variables are used to factor out calls to `expand_assignment'

9955: * cplus-tree.c (layout_basetypes): Same change.

9999: REG; it might be BLKmode.

10027: INDIRECTABLE_CONSTANT_ADDRESS_P, and INDIRECTABLE_ADDRESS_P, which
10028: are used when NO_EXTERNAL_INDIRECT_ADDRESS is defined. Also, define
10029: INDIRECTABLE_CONSTANT_ADDRESS_P. Modify definitions of
10030: GO_IF_NONINDEXED_ADDRESS, and GO_IF_LEGITIMATE_ADDRESS to work with

10511:
10512: * mips.md (movsi_ulw): Allow unaligned register->register moves,

10539: * collect-osf.c (various): General rewrite to improve speed and
10540: portability.
10541:
10542: * Makefile.in (CPLUS_OBJS): If CPLUS_INPUT is defined to be

10544: bootstraping when it is included in cplus-lex.c.
10545: (STAGESTUFF): Use $(LANGUAGES) instead of hard coded list of
10546: languages, so make-xxx file can override, and provide others.
10547: (gnulib2.ready): Make gnulib2 depend on all LANGUAGES targets, so
10548: that if a target needs something else built, such as mips-tfile, it
10549: will be.
10550: (mostlyclean): Add missing -f to rm.
10551: (install-dir): Use test to see if the directory exists before trying
10552: to create it, and fail if the mkdir fails.
10553: (install-headers): ditto.
10554: (stage?, risky-stage?): ditto.
10555: (install-cross): Install collect and mips-tfile if they are present.
10556:

10558: the original output file to the given file.
10559:
10560: * cplus-lex.c (toplevel): Include <assert.h> instead of "assert.h"

10562: uses <assert.h>.
10563:
10564: * cplus-pt.c (toplevel): Move include of config.h before obstack.h
10565: in case config.h defines some macros obstack.h uses such as

10572: Tue Jul 23 12:26:01 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
10573:
10574: * function.c (instantiate_virtual_regs_1): Change dubious code that
10575: used to assign NEW to XEXP (x, 1) regardless of whether
10576: validate_change accepted it to instead set XEXP (x, 0) back to OLD.
10577: I.e., if the rtx is out of range and OBJECT is NULL, don't make any
10578: change at all.
10579:
10580: * out-sparc.c (compute_frame_size): If a function has any
10581: stack-local objects, it's frame size is non-zero and space must be

10584: * loop.c (loop_optimize): Use get_max_uid to compute max_uid_for_loop.
10585:
10586: * fold-const.c (size_int): Extend SIZE_TABLE's range from
10587: 0..HOST_BITS_PER_INT-1 to 0..2*HOST_BITS_PER_INT.
10588:
10589: * integrate.c (expand_inline_function): Add minor efficiency
10590: hack to not free all the temp slots as parameters are passed
10591: from "caller" to "callee".
10592:
10593: * integrate.c (expand_inline_function): If the inline function
10594: returns its value via a structure_value_addr, we must prepare for
10595: this to take place, even if the value is ignored by the caller.
10596:
10597: * tm-decstatn.h (SIZE_TYPE): Define this to be "unsigned int".
10598:
10599: * emit-rtl.c (try_split): If `split_insns' actually returns a SEQ
10600: which is isomorphic to PAT, return TRIAL.
10601:
10602: * out-sparc.c (eligible_for_epilogue_delay): FP register moves are
10603: only eligible for leaf-function epilogue delay slots.
10604:
10605: Tue Jul 23 11:52:50 1991 Michael Meissner (meissner at geech.gnu.ai.mit.edu)
10606:
10607: * dbxout.c (dbxout_symbol): Correct typo in getting static member
10608: names. The problem is DECL_ASSEMBLER_NAME returns a tree, and not a
10609: char *.

10624:
10625: Mon Jul 22 15:25:48 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
10626:

10645:
10646: Sun Jul 21 18:45:57 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
10647:
10648: * toplev.c (rest_of_compilation):
10649: Save and restore DECL_INITIAL if we use save_for_inline_copying.
10650: * integrate.c (save_for_inline_copying): Really copy DECL_INITIAL.
10651: Calling integrate_decl_tree doesn't do it; deleted that call.
10652: (copy_decl_tree): New function.
10653:
10654: * integrate.c (integrate_decl_tree): Renamed from copy_decl_tree.
10655: (integrate_parm_decls): Renamed from copy_parm_decls.
10656:
10657: * tree.c (copy_chain): New function.
10658:
10659: Sun Jul 21 06:43:23 1991 James Van Artsdalen (james at bigtex.cactus.org)
10660:
10661: * i386.md (tstsi): Add comment noting potential -m486 enhancement.
10662: (SImode push): With -m486, don't push from MEM.

10665: (zero_extendhisi2,zero_extendqihi2,zero_extendqisi2): If dest is
10666: %eax, or if -m486, AND is faster than MOVZX.
10667:
10668: Sun Jul 21 06:27:33 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
10669:
10670: * expmed.c (store_fixed_bit_field): Pass actual bit position (including
10671: offset) to get_best_mode; also limit mode size to BITS_PER_WORD.
10672: Use failure of get_best_mode to indicate that field spans word
10673: boundary.
10674: Pass actual bit position to store_split_bit_field.
10675: (store_split_bit_field): Accept actual bit position, hence handing
10676: bitpos > BITS_PER_WORD.
10677: Abort if BITPOS and BITSIZE don't cross exactly one word boundary.
10678: Pass offset to store_fixed_bit_field; if register, use operand_subword;
10679: else adjust offset for second word.

10681:
10682: Sun Jul 21 06:11:55 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
10683:
10684: * All cplus-* files: DECL_VIRTUAL_P is no longer applied to
10685: FUNCTION_DECLs. Instead, to test if a function is virtual or not,
10686: it suffices to test whether its DECL_VINDEX is non-NULL. We use
10687: ERROR_MARK_NODE as the placeholder for a FUNCTION_DECL we know will
10688: be virtual, but for which we don't yet know the actual index.
10689:
10690: * cplus-decl.c (define_function): Don't set up DECL_ASSEMBLER_NAME
10691: until after having the chance to call through PFN. Since `pushdecl'
10692: now keys off of DECL_ASSEMBLER_NAME, we don't want to create
10693: inadvertent aliases between builtin and library functions.
10694:
10695: * cplus-typeck.c (build_modify_expr): We don't need to build a
10696: SAVE_EXPR for a WITH_CLEANUP_EXPR.
10697: (unary_complex_lvalue): For good measure, know how to deal with a
10698: WITH_CLEANUP_EXPR inside a SAVE_EXPR.
10699:
10700: * cplus-pt.c (uses_template_parms): Add handler for ARRAY_TYPE.
10701:
10702: * cplus-method.c (do_inline_function_hair): Use TYPE_METHODS instead
10703: of CLASSTYPE_METHOD_VEC for traversing all methods when looking for
10704: inline functions.
10705:
10706: * cplus-class.c (finish_struct_methods): Fix fencepost error if
10707: there were no member functions except for ctors/dtors.
10708:
10709: Sun Jul 21 06:19:01 1991 James Van Artsdalen (james at bigtex.cactus.org)

10716:
10717: * calls.c (expand_call): Set current_function_calls_longjmp if
10718: this call is to `longjmp'.
10719:
10720: * flow.c, global-alloc.c: Include output.h so that
10721: FRAME_POINTER_REQUIRED can use current_function_calls_*.
10722: * Makefile.in (flow.o,global-alloc.o): Includes output.h.
10723:
10724: * rtl.h (FUNCTION_FLAGS_CALLS_LONGJMP): New macro.
10725:
10726: * integrate.c (initialize_for_inline): Record
10727: current_function_calls_lonjmp in `function_flags'.
10728: (output_inline_function): Set current_function_calls_longjmp if
10729: the inline code calls longjmp.
10730:
10731: * function.h (struct function): New field `calls_longjmp'.
10732:
10733: * out-i386.c (simple_386_epilogue): Add function description.
10734: Return 0 if NON_SAVING_SETJMP && `setjmp' is called in function.
10735:
10736: * tm-i386v.h (NON_SAVING_SETJMP): New macro.
10737: (FRAME_POINTER_REQUIRED): New macro.
10738:
10739: Sat Jul 20 12:25:56 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
10740:
10741: * tm-m88k.h (OPTIMIZATION_OPTIONS): Don't change flag_signed_bitfields.
10742:
10743: * cccp.c (include_defaults) Use LOCAL_INCLUDE_DIR macro instead
10744: of "/usr/local/include". Provide default definition.
10745:
10746: * cccp.c (include_defaults) Added INCLUDE_DEFAULTS macro to
10747: provide complete control over default include directories.
10748: Delete the special case for VMS.
10749: * xm-vms.h (INCLUDE_DEFAULTS): Defined.
10750:
10751: * proto-man: Renamed from proto-unproto.1.
10752:
10753: * final.c (final_scan_insn): Do ASM_OUTPUT_LOOP_ALIGN only for real loop.
10754:
10755: Sat Jul 20 05:34:13 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
10756:
10757: * tree.h (tree_type): Use the MAXVAL slot for TYPE_METHODS.
10758: * cplus-class.c (finish_struct): Methods are now chained with
10759: TREE_CHAIN and placed in the TYPE_METHODS of their _TYPE node.
10760: * cplus-dbxout.c (dbxout_type_methods): Use this fact, instead of
10761: using more C++-specific knowledge.
10762:
10763: * cplus-decl.c (init_decl_processing): Variable
10764: `const_ptr_type_node' was not being initialized. Same with
10765: `const_string_type_node'.
10766:
10767: * tree.h (DECL_PRINT_NAME): Marked for death.
10768: (DECL_ASSEMBLER_NAME): Changed from a char* to a tree node.
10769: All front-end files changed as necessary.

10771: * cplus-tree.h (DECL_ORIGINAL_NAME): Deleted. Now we use
10772: DECL_NAME.
10773: (DECL_NAME): No longer means the mangled name. Now we use
10774: DECL_ASSEMBLER_NAME for that purpose.
10775: All cplus-* files changed as necessary.
10776:
10777: * cplus-tree.c (lang_printable_name): Use a ring-buffer to hold
10778: printable names instead of DECL_PRINT_NAME slot of a _DECL node.
10779:
10780: * collect2.c: #define COLLECT, and let config.h provide definition
10781: of macros.
