1587:
1588: * pa.h (TARGET_KERNEL): New switch "-mkernel" which forces gcc to

3956: Make sure VFIELD_BASEs are aligned. This fixes a really
3957: annoying problem that causes code that uses complex
3958: inheritance hierarchies that have virtual bases to get a
3959: segmentation fault.

4005: source accesses only.
4006: * caller-save.c (toplevel): All arrays are multi-dimensional to
4007: hold information for multiple save/restore insns. New variable
4008: hard_regs_need_restore.
4009: (choose_hard_reg_mode): New argument `nregs' indicating how many
4010: hard registers are desired. All callers changed.
4011: (init_caller_save): Change initialization to handle multiple
4012: register saves. A call-used register can not be live across
4013: if we can not find a single register mode to save it in.
4014: (multiple register saves are optional)
4015: (init_save_areas): Change initialization of regno_save_mem to
4016: handle multiple register saves.
4017: (setup_save_areas): Allocate space for consecutive hard registers
4018: in aligned consecutive memory locations. When allocating space
4019: for consecutive hard registers, also initialize regno_save_mem

4021: (save_call_clobbered_regs): Initialize hard_regs_need_restore.
4022: Set hard_regs_need_restore to hard_regs_saved after crossing

4025: (set_reg_live, clear_reg_live): Do the right thing for
4026: hard_regs_need_restore and hard_regs_saved.
4027: (restore_referenced_regs): Just return if X is a clobber.
4028: Test hard_regs_need_restore to determine when to restore a hard
4029: register from the save area.
4030: (insert_save_restore): Now returns the number of extra registers
4031: saved/restored. New argument `maxrestore' which constrains how
4032: many hard registers should be restored. All callers changed.
4033: Do stores of consecutive registers with double store insns if
4034: possible. Else do them with single word insns. Likewise for
4035: loads, except constrained by maxrestore. Set hard_regs_saved
4036: and hard_regs_need_restore appropriately to minimize useless
4037: saves into the save area. Test against hard_regs_need_restore
4038: when trying to restore multiple regs and similarly test against
4039: hard_regs_saved when storing multiple regs.

4054: (OBJECT_FILE_COFF): Undefine, since the DEC OSF/1 ldfcn doesn't
4055: look like the coff version.
4056:
4057: * decstatn.h (LINK_SPEC): Don't define if already defined.
4058:
4059: Wed Aug 26 13:56:08 1992 Tom Wood ([email protected])

4062: unconditional jump.
4063: (fill_simple_delay_slots): Look for the case of a call/branch
4064: first. If this applies, record the jump as `last_delay_insn'.
4065: Later, don't look for additional delay insns if the last one has
4066: alreay been filled.
4067: (mark_target_live_regs): A sequence may end in an unconditional
4068: branch.

4198: (ASM_FINAL_SPEC): Use %U to get the last file name created with
4199: %u, rather than %u.
4200: (ARG_POINTER_REGNUM): Use the hardwired register $0 as the
4201: argument pointer, instead of the frame pointer, to allow the frame
4202: pointer to be the same as the stack pointer after the initial
4203: stack allocations. This is to allow GCC generated code to be
4204: linked against MIPS shared libraries. The linker rearranges the
4205: code, and needs to have a frame pointer, if used, to be the same
4206: as the stack. The argument pointer is always eliminated in favor
4207: of the stack pointer or frame pointer.
4208: (FRAME_GROWS_DOWNWARD): Don't define this any more.

4210: arguments to called functions.
4211: (STACK_DYNAMIC_OFFSET): If function is a leaf function, but calls

4215: elimination instead.
4216: (ELIMINABLE_REGS): Define to eliminate both the stack pointer and

4220: (ELIGIBLE_FOR_EPILOGUE_DELAY): Don't allow variables based off of
4221: the argument pointer, in addition to frame and stack pointers.
4222: (MUST_SAVE_REGISTER): Add in GP_REG_FIRST to 31, in case we ever
4223: change the base of the gp registers.
4224: (MIPS_STACK_ALIGN): Use ~7, instead of 0xfffffff8.
4225:
4226: * mips.c (number_functions_processed): Delete variable, nobody
4227: uses it anymore.
4228: (mips_debugger_offset): Add support for the frame pointer being
4229: the same as the stack pointer, instead of being the same as the
4230: argument pointer. Abort if the address is not based on any of the
4231: stack, frame, or argument pointers.
4232: (print_operand_address): Add checks for the arg pointer not being
4233: eliminated.
4234: (function_prologue): Ditto.

4239: current_function_name when printing statistics. Delete increment
4240: of number_functions_processed.
4241: (compute_frame_size): Don't base extra_size on the macro
4242: STARTING_FRAME_OFFSET. If function is a leaf function, but calls
4243: __builtin_alloca, allocate an arg area, so that the MIPS linker
4244: will not complain about creating a second frame pointer. Move the
4245: argument save area beneath local variables.
4246:
4247: * decrose.h (ASM_FINAL_SPEC): Use %U to get the last file name
4248: created with %u, rather than %u.
4249:
4250: * gcc.c (do_spec_1): Add %U to return the last name generated with
4251: %u. This is for use with mips-tfile, to find the generated object
4252: file.
4253:
4254:
4255: Mon Aug 24 18:09:34 1992 Richard Stallman ([email protected])

4261:
4262: * gcc.c (process_command): Don't set verbose_flag if they make a

4999:
5000: Sat Aug 8 07:36:19 1992 Tom Wood ([email protected])
5001:
5002: * cp-lex.c: Include stdlib.h and locale.h if needed.
5003: (errno): Declare only if it isn't a macro.
5004: * cp-tree.c (__eprintf): `line' is unsigned.

5006:
5007: Fri Aug 7 00:16:28 1992 Richard Stallman ([email protected])
5008:
5009: * gcc.c (read_specs): Cast args of xmalloc and read to unsigned.
5010:
5011: * final.c (final_scan_insn): Use ASM_OUTPUT_ADDR_DIFF_ELT

5015:
5016: * sched.c (true_dependence): An unchanging read is guaranteed
5017: independent of a store only if the store is not unchanging.
5018: (anti_dependence): Added comment about unchanging reads.
5019: (sched_analyze_2): Don't ignore unchanging reads, they may be
5020: dependent on unchanging writes.
5021:
5022: * sparc.md: Correct DEFINE_SPLITs added Jul 27. They would
5023: overwrite the input register if it was the same as the result reg.
5024:
5025: Thu Aug 6 16:25:48 1992 Jeffrey A. Law ([email protected])
5026:
5027: * pa.h (ASM_FILE_START): If profiling IMPORT "_mcount" instead of
5028: "__gcc_mcount".
5029:
5030: * These changes allow the PA to make use of the BSS subspace. They
5031: require you to use the HPUX assembler or a fixed version of pa-gas
5032: (available soon on jaguar.cs.utah.edu).
5033: * pa.h (TARGET_SWITCHES): New switch "no-bss" which forces gcc not
5034: to make use of the bss subspace. (For compatability with old buggy
5035: versions of pa-gas.)
5036: (ASM_FILE_START): Add $BSS$ subspace.
5037: (BSS_SECTION_ASM_OP): New macro which tells the assembler to switch
5038: to the bss subspace.
5039: (EXTRA_SECTIONS): Define in_bss as an extra section.
5040: (EXTRA_SECTION_FUNCTIONS): Define "bss_section" function to switch

5056: * m88k.h (EXTRA_SECTIONS, svr3): Delete empty definitions for
5057: CTORS_SECTION_FUNCTION and DTORS_SECTION_FUNCTION. Add in_ctors
5058: and in_dtors.
5059:
5060: Tue Aug 4 23:54:15 1992 Richard Stallman ([email protected])
5061:
5062: * gcc.c (default_compilers): For output of as when -c is not used,
5063: use %g, rather than %b, because the file is going to be deleted
5064: anyway.
5065:
5066: Tue Aug 4 20:30:12 1992 Michael Meissner ([email protected])
5067:
5068: * cp-decl.c (grokdeclarator): Call build_type_variant to set const
5069: and volatile flags, since build_reference_type does not take those
5070: arguments.
5071:
5072: * cp-parse.y (attribute processing): Correctly call tree_cons with
5073: three arguments, passing NULL_TREE for the chain argument.
5074:
5075: * cp-tree.h (hash_chainon): Add declaration for this function.
5076: (build_virtual_init): Ditto.
5077: (build_vbase_delete): Ditto.

5081: build_unary_op.
5082: (build_modify_expr): Ditto.
5083:
5084: Tue Aug 4 18:10:46 1992 Mike Stump ([email protected])
5085:
5086: * cp-tree.h, tree.h: Moved definitions of TREE_VIA_* into tree.h for
5087: consistency.

5091: Complete 10th FSF <---> Cygnus merge.
5092:
5093: Tue Aug 4 12:58:59 1992 Mike Stump ([email protected])
5094:
5095: * cp-decl.c (pushtag): Don't set DECL_IGNORED_P for binding
5096: layer markers, use only DECL_SOURCE_LINE == 0, as otherwise,
5097: it messes up dbxout.c.
5098:
5099: Tue Aug 4 11:59:36 1992 Mike Stump ([email protected])
5100:
5101: Tue Aug 4 13:43:55 1992 Chip Salzenberg ([email protected])

5105:
5106: Tue Aug 4 10:23:02 1992 Chip Salzenberg ([email protected])
5107:
5108: * cp-decl.c (pushdecl): Any kind of DECL should be good enough
5109: at global scope, not just a TEMPLATE_DECL.
5110:

5115:
5116: Fri Jul 31 16:53:26 1992 Mike Stump ([email protected])
5117:
5118: * cp-tree (break_out_calls): Only make ony copy of a node on
5119: 's' and 'e' nodes. Handle 'r' just like 's' and 'e' because
5120: nodes of type 'r' can be of different sizes (the old code
5121: would do the wrong thing for a COMPONENT_REF).
5122:
5123: Thu Jul 30 11:46:14 1992 Michael Tiemann ([email protected])
5124:
5125: * cp-init.c (emit_base_init): Set transparent basetypes (those w/o
5126: ctors) as marked if we need to walk up the tree to find a ctor.
5127:
5128: Wed Jul 29 03:25:51 1992 Michael Tiemann ([email protected])
5129:
5130: * cp-decl.c (grokdeclarator): In SCOPE_REF case, sort out visibility
5131: declarations from other declarations, since the compiler will
5132: ultimately handle them differently. This is a part of the solution
5133: to p525.
5134: (finish_method): Tentative (and probably wrong) fix for carrying
5135: along inline methods delcared within a class that really belong to
5136: nested classes of the class. This may be more of the solution to
5137: p525.
5138:
5139: * cp-init.c (build_offset_ref): Use IDENTIFIER_TYPE_VALUE of CNAME
5140: when CURRENT_CLASS_DECL is 0.
5141:
5142: * cp-class.c (finish_struct): Don't give errors for TYPE_DECLs in a

5146:
5147: * cp-decl.c (grok_op_properties): Do not core dump on parse errors.
5148:
5149: Tue Jul 28 22:43:12 1992 Mark Eichin ([email protected])
5150:
5151: * cp-pt.c (end_template_instantiation) YYDEBUG is now defined in
5152: cp-parse.h -- so don't assume that it's -2 (since under byacc it is
5153: -1 anyway.) iomanip.C compiles again.
5154:
5155: Tue Jul 28 22:33:46 1992 Mike Stump ([email protected])
5156:
5157: * cp-typeck.c (build_c_cast): Allow cast to array type in

5159:
5160: Tue Jul 28 22:05:14 1992 Mark Eichin ([email protected])
5161:
5162: * cp-parse.y (print_parse_statistics): don't reference TOKEN_LENGTH
5163: or REDUCE_LENGTH unless GATHER_STATISTICS is set. (YYDEBUG alone is
5164: not a sufficient condition.)
5165:
5166: Tue Jul 28 19:18:30 1992 Mike Stump ([email protected])
5167:
5168: * cp-tree.c (break_out_calls): Don't do anything special to
5169: SAVE_EXPRs, as they cannot contain calls that would need
5170: breaking out. This fixes a problem introduced on Jul 15, by
5171: Ron Guilmette.
5172:
5173: Mon Jul 27 16:55:52 1992 Mike Stump ([email protected])
5174:
5175: * c++: Fix errors introduced by rms. Bullet-proof handling
5176: of arguments with funny things in them such as newlines,
5177: spaces, tabs, single quotes, double quotes, etc...
5178:
5179: Mon Jul 27 15:03:23 1992 Ken Raeburn ([email protected])
5180:
5181: * cp-init.c (build_vec_delete): Extract size of type even for
5182: destructorless types, so value can be computed to pass to delete
5183: operator.
5184:
5185: * Bludgeon interface/implementation code into leaving templates
5186: alone, until we've figured out how to handle their interaction
5187: properly:
5188: * cp-parse.y (template_instantiate_once): Temporarily set interface
5189: flags to `unknown' while processing member templates.
5190: * cp-decl.c (grokfndecl): Even if class vtable is getting written
5191: out, regardless of interface setting of class and write_virtuals
5192: flag, don't force virtual destructor of template class to be public.
5193: * cp-tree.h (struct pending_inline): New field `interface'.
5194: * cp-lex.c (do_pending_inlines): Restore interface flags from stored
5195: values, rather than calling extract_interface_info.
5196: (process_next_inline): Likewise, if more pending inlines exist; else
5197: do call extract_interface_info.
5198: (reinit_parse_for_method): Save away interface flags.
5199: (cons_up_default_function): Ditto.
5200: * cp-pt.c (instantiate_template): Set saved interface flag to

5203:
5204: * cp-pt.c (instantiate_member_templates): Deleted some unused code.
5205:

5207: `implementation' pragma is set.
5208:
5209: * cp-pt.c (pending_templates): No longer exported.
5210: (add_pending_template): Ditto.
5211: * cp-parse.y (primary): Don't check it; always call
5212: do_pending_templates.
5213:
5214: Fri Jul 24 14:22:39 1992 Mike Stump ([email protected])
5215:
5216: * cp-decl.c (init_decl_processing, finish_function),
5217: cp-method.c (build_decl_overload, build_opfncall), cp-init.c
5218: (build_x_delete, build_delete, build_vec_delete): Add support
5219: for two argument delete to support ARM 12.5. In some cases,
5220: the argument is smaller than it should be.
5221:
5222: Thu Jul 23 08:12:16 1992 Mike Stump ([email protected])
5223:
5224: * cp-lex.c: Update wide character handling from c-lex.c and make

5233: Wed Jul 22 17:41:08 1992 Mark Eichin ([email protected])
5234:
5235: * cp-parse.y (structsp): note_got_semicolon was called before
5236: finish_struct (which always clears the got_semicolon bit.) However,
5237: note_got_semicolon was only called if yychar==';', without checking
5238: for YYEMPTY.
5239:
5240: Tue Jul 21 22:59:32 1992 Michael Tiemann ([email protected])
5241:
5242: * cp-typeck.c (mark_addressable): If we have a recursive call to an
5243: otherwise inline function, clear TREE_EXTERNAL so the whole function

5257: template parameter.

5260:

5266:
5267: * c-decl.c (finish_decl): Don't do expand_decl_init for FUNCTION_DECL.
5268:
5269: * c-typeck.c (build_conditional_expr): Merged const and volatile flags
5270: of incoming types.

5274: * c-decl.c (finish_struct): If bit field is of an unsigned
5275: type that promotes to int, promote it unsigned if traditional
5276: or if it is the same size as int.
5277: (start_function): Ditto for function return value.
5278: * c-typeck.c (default_conversion): Ditto -- fix bug that
5279: promotes short to unsigned if sizeof(short) == sizeof(int).
5280:
5281: Tue Aug 4 15:12:51 1992 Tom Wood ([email protected])

8020:
8021: * cp-call.c (build_method_call): Use DECL_CLASS_CONTEXT, not

8023: non-virtual calls).
8024:
8025: Tue May 19 02:08:39 1992 Mike Stump (mrs at cygnus.com)

8041:
8042: * cp-parse.y (template_type_name): Handle

8067:
8068: * cp-decl.c (poplevel): Reconciled with recent changes made to the
8069: `poplevel' routine in c-decl.c. The changes here cause LABEL_DECL

8071: which represent the outermost scope of the function.
8072:
8073: Mon May 11 12:35:44 1992 Ron Guilmette (rfg at ncd.com)
8074:
8075: * cp-class.c (finish_struct): Check DECL_CONTEXT to see if it is
8076: any sort of a type (e.g. struct *or* union) rather than just
8077: checking it to see if it's a RECORD_TYPE.
8078: * cp-decl.c (pushdecl): Set DECL_CONTEXT of pushed ..._DECL node,
8079: just as is done in c-decl.c.

8101:

8105: 3/18/92.
8106:
8107: Sun May 3 00:29:59 1992 Mike Stump (mrs at cygnus.com)

8111:
8112: Fri May 1 12:22:31 1992 Michael Tiemann ([email protected])
8113:
8114: * cp-init.c (expand_aggr_init, expand_vec_init): When comparing
8115: array types, use `comptypes' instead of ==, since two array types

8117: an initializer.
8118:
8119: Wed Apr 29 01:25:25 1992 Mike Stump (mrs at cygnus.com)
8120:

8134:
8135: * mips.c (large_int): Rework, so that we don't get funny boundary
8136: conditions on systems with 64 bit integers.
8137: (mips_move_1word): Just use li to load constants that can be done
8138: with lui, instead of issuing the lui, since the GAS bug that
8139: generated two instructions has been fixed.
8140: (final_prescan_insn): Move the checking for filling the delay
8141: slots here from the FINAL_PRESCAN_INSN macro.
8142:
8143: * mips.md (andsi3, iorsi3, xorsi3): Make the constraints match
8144: the real machine (the predicate still is more general in order
8145: to optimize bitfields at the expense of not CSE'ing large
8146: constants used in logical ops, and making reload load it into
8147: a scratch register). Don't use $1 as a temporary register any
8148: more.
8149:
8150: * varasm.c (decode_reg_name): If `memory' return -4.
8151:
8152: * stmt.c (expand_asm_operands): If `memory' is used as a clobbered

8154: to cache memory values in registers across the assembly
8155: instruction(s).
8156:
8157: * mips-tfile.c (read_line): Semicolons within strings are not
8158: counted as statement separators.
8159:
8160: * collect2.c (scan_prog_file, OSF/rose case): Cast pointer arguments
8161: to bcopy to generic * to avoid warnings.
8162:
8163: Thu Jun 18 12:04:53 1992 David J. MacKenzie ([email protected])
8164:
8165: * c++: If given -v with no file args, don't pass the libraries to
8166: gcc.
8167:
8168: Thu Jun 18 10:34:22 1992 Tom Wood ([email protected])
8169:
8170: * expr.c (expand_builtin, BUILT_IN_FSQRT): Emit queue of increment
