998 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1000 * configure.in: Set bfd_gas for all sparc targets in one place,

1004 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1006 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
1009 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
1010 processing if add_symbol is undefined or in expr_section.
1011 (resolve_symbol_value, case O_add): For symbol plus
1012 constant-valued symbol, convert to O_symbol and re-reduce.
1013 (S_GET_VALUE): If symbol needs resolving, resolve it.
1014 (indent_level): No longer static.
1015 (print_symbol_value_1): Don't print frag address if it matches
1016 zero_address_frag. Don't print "resolving" if already resolved.
1017 Print segment name. Don't call print_expr_1 on an undefined
1019 (print_expr_1): Fix whitespace before printing X_add_number.
1021 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1022 not symbol_new, for symbols holding expression values.
1023 * expr.h (make_expr_symbol): Move declaration here.
1024 * write.c (fix_new_exp): Handle O_add by creating an
1025 expression-valued symbol, and calling fix_new_exp recursively.
1026 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1027 undefined symbol and a constant, fold the constant into the fixup,
1028 and refer to the undefined symbol directly. Then process the
1029 fixup again from scratch.
1030 (write_object_file): Before calling adjust_reloc_syms, make a pass
1031 through the symbol list trying to resolve values.
1033 * write.c (print_fixup): New routine, for debugging.
1034 (write_relocs): Call bfd_install_relocation. Deleted various
1035 hacks for working around problems with bfd_perform_relocation.
1037 * Makefile.in (VERSION): Update to 2.4.90.

1045 not assembling PIC code, replace it with a j or jal.
1047 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1048 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

1052 * write.c (write_relocs): Add file name and line number to
1053 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1054 RELOC_EXPANSION_POSSIBLE.
1056 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1058 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1059 here. Use them for deciding which PRINTF*LIKE macro definitions
1061 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1062 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1063 default definitions matching what we were doing before.
1064 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1065 always use the varargs form if not using stdarg. It's safe to
1066 always use vfprintf, because libiberty will provide it if the
1067 native system doesn't. Also, always make format be const.
1068 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

1083 (listing_newline): Check filename as well as line number when
1084 deciding whether to record it.
1085 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1086 false (if defined) as well as checking for reg_section.
1087 (listing_listing): Iterate fetching lines while line number is too
1088 low, and we haven't run off the end of the input file.
1090 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1092 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1094 * ecoff.c (ecoff_generate_asm_lineno): check if

1101 * config/ho-*.h: Now-unused files deleted.
1103 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1104 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1105 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1106 zero. Don't call obj_frob_forward_symbol.

1109 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1111 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1113 (strchr): Don't declare.

1115 md_estimate_size_before_relax, md_ri_to_chars,
1116 md_create_short_jump, md_create_long_jump.
1117 (brtab_emit): Use data_section, not SEG_DATA.
1119 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1121 * config/vms-conf.h: new file, manually derived from conf.in.
1122 * config-gas.com: use it, and eliminate obsolete "host.h".

1126 * config/tc-ppc.c (ppc_current_block): New static variable.
1127 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

1132 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1133 from the csect of the enclosing block.
1135 * config/tc-mips.c (insns_since_cache_access): Remove.
1136 (append_insn): Remove setting of insns_since_cache_access, and
1137 special 4600 handling; it turns out not to be required.
1139 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1141 * config/tc-mips.c (md_shortopts): Remove E.
1142 (md_longopts): Add EB and EL.
1143 (md_parse_option): Handle -EB and -EL as separate options, rather
1144 than as a single -E option with an argument.

1153 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1155 * configure.in: Test for remove, not delete. Fix cross-assembler
1157 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1160 * read.c (pseudo_set, case O_symbol): If
1161 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1162 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1163 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1165 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1167 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1168 many others): new macros; values obtained from "DSTRECRDS.SDL".
1169 * config/obj-vms.h (various): use them.
1170 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1171 representation (only enum bitfields can avoid being bitstrings).
1172 (bitfield_suffix, setup_basic_type): new routines.
1173 (VMS_typedef_parse): use them. Now recognize bitfields of all
1174 integral types, not just type `int'. Caveat: the representation
1175 used for bitfields still does not work for objects placed in
1176 registers, and gcc's optimizer sometimes puts small structs there.
1178 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1180 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1181 bit from const_flag.
1182 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1183 (tc_frob_label): define this to call vms_check_for_special_label,
1184 and declare the latter.
1185 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1187 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1188 (vms_check_for_special_label): new routine (tc_frob_label).
1189 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1190 and `gcc2_compiled.' labels; they won't reach here any more.
1191 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1192 double', use `vax_g_doubles' flag to select type of double.
1193 (VMS_write_object_file) [traceback setup]: don't pass symbols
1194 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1195 and TBT_Routine_End functions.

1199 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1200 S_GET_VALUE() to avoid many repeated function calls.
1201 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1202 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1203 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1204 be obsolete; gcc does it automatically for vms target. It's
1205 also misnamed, because it is for the "VAX C" run-time library,
1206 not the newer "DEC C" one which has much different startup code.]
1207 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1208 `S_GET_xxx(symbol) = new_value'.
1210 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1212 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1213 not &bfd_abs_section.
1215 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1217 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1219 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1221 * expr.c (expr): Don't reduce the difference of two symbols in the
1222 same frag if the symbols are not in normal sections.
1224 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1225 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1226 (obj_attach_unwind_info): Do not define. Not needed anymore.
1227 * config/tc-hppa.c: Delete whitespace at EOL.
1228 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1229 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1230 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1231 fixups, store 32bits of unwind information in the fx_addnumber
1233 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1234 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1235 pointer to 32 bits of unwind info.
1236 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1237 pointer to the dummy symbol; set the addend field to fx_addnumber.
1238 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1239 rather than &bfd_XXX_section.
1241 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1243 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1244 value by one; discard adjustments previously being made. From
1247 VMS- and Vax-related changes from Pat Rankin:
1248 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1249 * vmsconf.sh: no longer have make-gas.com echo text about needing
1250 to modify the gcc-vms driver when intending to use with gcc 1.x.
1251 * as.c (parse_options): suppress 'v' from std_short_options and
1252 eliminate VMS-specific conditional initialization;
1253 [default case]: check for '-v' if md_parse_options doesn't recognize
1255 [default case, #if VMS]: check for filename argument when '-v' seen;
1257 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1258 for O_big literal operands (double floats and long long ints);
1259 [VMS, md_shortopts]: add second colon after 'v';
1260 (md_parse_options) [VMS, case 'v']: check for argument, so
1261 caller can handle `-v' w/o arg.

1319 to ensure that older versions of autoconf aren't used.
1320 * Makefile.in: Added @configure_input@ line.
1321 (configure): Deleted rule.

1325 * config/obj-coff.c (fixup_segment): After handling the difference
1326 of two symbols from the same segment, set fx_subsy to NULL, to
1327 satisfy existing TC_COUNT_RELOC macros.

1402 reportedly to be used on Irix 6.
1404 * config/tc-mips.c (md_pseudo_table): Handle .globl and .global.
1405 (s_mips_globl): New static function; needed for Irix 5 support.
1406 * ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
1407 external symbol with no type, set the type to st_Proc rather than

2362 * listing.c (list_symbol_table): Only test BFD64, not
2365 * config/obj-coff.c (fixup_segment) [BFD_ASSEMBLER]

2385 VMS debugger now recognizes `long long' variables correctly.
2386 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
2387 for gcc2's predefined types "long double" (same as double, as
2388 per gcc's current state), "long long int", "long long unsigned
2389 int", and final `otherwise' case (to avoid uninitialized type
2390 and size fields). [caveat: predefined types "complex int",
2391 "complex float", "complex double", and "complex long double" are
2394 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
2395 of 0, because the latter indicates success rather than failure

2399 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.

2438 * config/tc-hppa.c (pa_parse_fp_cmp_cond): Report an error
2439 on a partial completer match.

2851 don't spew remainder of input file in error message.
2852 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2853 message with reloc type and try to process remainder of file.

2865 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2866 flag rather than signedp field. Only permit extended range if
2867 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.

2870 * config/tc-ppc.c (ppc_size): New static variable.
2871 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2872 (md_begin): If an instruction has a size specific flag set, only
2873 add it if we are assembling that size.

2877 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2878 cross section PC relative relocs right for COFF and ELF.
2880 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2906 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2908 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2909 branch with an instruction that uses $at, in case the branch is
2911 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.

2913 to make it pcrel_offset.
2914 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to

2924 (md_assemble): Call it.
2925 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2927 (lituse_pending): New variable. Set by anything that generates a
2928 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2929 tested by code that might want to emit a LITUSE reloc.
2930 (emit_unaligned_io): New function. Currently calls md_assemble,
2931 but it should eventually be converted to generate the insn itself
2932 and call emit_insn directly.
2933 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2934 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2935 emit_bis_r): Likewise.

2946 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2947 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

2963 (load_address): Handle EMBEDDED_PIC.
2964 (macro): Handle EMBEDDED_PIC in all PIC cases.
2965 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2966 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2967 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2968 works). Do not permit -G with SVR4_PIC.
2969 (s_abicalls): Warn if -G was used, and force -G 0.
2970 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2971 anything but a.out, not just for ELF. For ECOFF, don't generate a
2972 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2974 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.

2982 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2984 * Makefile.in (config-stamp): If `defs' is defined, emit a
2985 preprocessor directive to create a macro named by this value into
2986 config.new; don't explicitly go for BFD_ASSEMBLER.
2987 * configure.in: Define `defs', not `BFDDEF'. Set it to
2988 MANY_SEGMENTS for any obj-coffbfd target.
2989 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2990 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,

3020 bfd_set_symtab is called.
3021 (dump_section_relocs): Note whether a symbol is a section symbol
3023 (adjust_reloc_syms): For now, always supply an absolute symbol for
3024 fixups without symbols but not yet `done'. Use section_symbol to
3025 get the symbol, instead of going directly for abs_symbol.
3026 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3027 reloc is not a section symbol and is not in the symbol table.
3028 (set_symtab): New function, broken out from write_object_file.
3029 Counts symbol table instead of relying on an earlier count.
3030 (write_object_file): Call set_symtab, but do it after potentially
3031 invoking the *_frob_file macros. Don't bother counting symbols.
3032 Call symbol_remove, instead of expanding it in place. Moved the
3033 conditionalized `object_file_size' declaration down to
3034 conditionalized block where it's used. When using the absolute
3035 symbol for a fixup without a symbol, set sy_used_in_reloc.
3036 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3037 the correct symbol for the absolute section.
3039 * subsegs.c (section_symbol): Use symbol_new instead of
3040 symbol_make, since we may want it to go into the symbol table.
3041 Make the new symbol have internal linkage. If
3042 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3043 symbol with the newly created GAS symbol.
3044 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3045 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

3052 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3053 (sparc_ip, label "immediate"): Reject constants for pcrel
3054 instructions only if the relocation type indicates a "call"
3055 instruction and the offset is within range of a "jmpl %g0". If
3056 it's not in range, use the absolute section symbol plus an offset.
3057 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3059 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3061 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3064 * configure.in: Eliminated all targets using obj-coff but not
3065 defining BFD_ASSEMBLER; I think all such targets that are
3066 supported will be matched by real CPU-OS combinations earlier in
3068 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3069 some comments about the dpx2 configuration, but left it disabled,
3070 since it couldn't be reached before.
3071 (target a29k-amd-ebmonold): Deleted.
3073 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3081 the 'j' operand if there are no further alternatives for this
3084 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3085 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3086 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3088 * config/tc-mips.c (mips_align): Take new argument, label, and use
3089 it instead of global insn_label.
3090 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3091 call to mips_emit_delay and pass it to mips_align.
3093 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3095 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3097 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3098 argument to a .callinfo directive. Don't loop forever on errors.

3105 * write.c (write_object_file): Check both S_IS_LOCAL and
3106 S_IS_EXTERNAL when deciding whether to discard a symbol.
3108 * config-gas.com: Scan Makefile.in, not version.c, for current
3109 version number. Delete all versions of temp files when finished
3110 with them. Create config.h.
3112 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
3113 values to reduce number of lookups with S_GET_VALUE. Skip debug
3114 symbols to avoid "a really nasty bug". (From Holger Teutsch,
3115 holger@botbso.rhein-main.de.)
3116 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
3117 field. (Also from Holger Teutsch.) Watch for a would-be register
3118 mask that spans frags.
3120 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
3121 this_base, not line_base. (Patch from Andreas Arens,
3122 ari@obelix.av.rwth-aachen.de.)
3124 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
3125 look local if they're exported or undefined. Used to be done for
3128 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
3129 Get it from the looked-up symbol, instead of using the string from
3130 the input stream, which is no longer null-terminated.
3131 (LEX_PCT): New macro, defaults to 0.
3132 (lex_type): Use it for `%'.
3134 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

3184 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
3185 0xffff for 'j' to be compatible with MIPS assembler. These

3275 (tc_bout_fix_to_chars): Store symbol index for all callx
3276 relocations, regardless of link-relax setting.

5259 default is to assume production environment, and reject configs
5260 still being worked on. Mark Elf configurations (except sparc and
5261 i386) as developmental. Deleted cases matching some generic names
5262 in favor of more specific names. (E.g., when we get Alpha

5288 into a few places. Make all functions and variables which
5289 are only used within tc-hppa.c static. PARAMize all functions.
5290 Add comments to functions. Delete unused functions, variables,
5291 #defines, etc. Delete unused members within structures. Delete
5292 ldil;ble hacks -- it is believed they were installed to work
5293 around old gas bugs. Avoid using mixed case for local
5294 functions, variables, and structures. Fix formatting problems
5295 not found by GNU-indent. Add FIXME notices for things which
5296 should be worked on the near future. Delete lots of old
5297 useless (1.36 PA-SOM) code.

5316 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
5317 of elf32_symbol_type.
5318 (pa_export_args): Likewise.

5326 a multiple of the section alignment rather than always a
5329 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

5376 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5378 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5379 ELF, since the ELF object format does not have these type of
5380 relocations. Change the abort into as as_bad and return
5381 BFD_RELOC_NONE to silence compiler warnings.
5382 (md_assemble): Keep track of the instruction size. Allow white
5383 space between the $ and the constant for compatibility with older
5384 gases and other assemblers.

7828 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7835 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

7868 dropping a space immediately following an identifier.

7870 lines; I don't think that can be done portably.
7871 * config/tc-mips.c (macro): Use $AT if target register is zero in

7946 prototypes for all static functions. Moved existing minimal
7947 debugging format support info #ifndef OBJ_ECOFF blocks.

7996 * make-gas.com: Find obstack.obj if it's not in the current
7998 * read.c (s_ignore): Don't declare is_end_of_line. It's
7999 redundant, and triggers a VMS gcc compiler bug.
8001 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8002 current segment as an argument. (Ignored in all cases but VMS.)
8003 All callers and definitions changed.

8027 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8030 * configure.in: mips-bsd configuration was missing format spec.
8033 * Makefile.in (Makefile): Depends on configure.in.
8035 * config/tc-mips.c (append_insn): Don't check for alignment of
8036 frag in memory; alignment of instructions in section is a separate

8056 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8057 constants are accepted, but symbolic values are not. GCC will not
8058 generate the latter currently.
8060 * frags.c (frag_init): New function.
8061 (zero_address_frag, bss_address_frag): Now initialized at run
8063 * as.c (main): Call frag_init.

8334 (operand): Treat zero byte as end-of-operand.
8336 * configure.in (per-target): Look for with_bfd_assembler option.
8337 For now, only accept "no", until the merge is done.
8339 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8340 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8341 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8342 * read.c: Finish conversion to S_* macros in the VMS only
8343 parts of the program. Add "const" modifier to hex_value.

8346 * expr.c: Add "const" modifier to hex_value.
8347 * symbols.c: Finish conversion to S_* macros in the VMS only
8348 parts of the program. Add "const" modifier to
8349 md_[long,short]_jump_size. Remove declaration of const_flag
8350 (which will be declared in obj-vms.h).
8351 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8352 Fix arguments to VMS_write_object_file.
8353 * config-gas.com: New file. Script for VMS systems to set up the

8413 mapping to segT enum values.
8414 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8415 if these are used or defined, if BFD_ASSEMBLER.
8416 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8417 subseg_new split into two functions.

8420 * as.h (volatile): Don't define if already defined.
8421 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8423 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8424 declare with format attribute for -Wformat checking.
8426 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8428 * app.c, config/tc-*.c: Don't include read.h, since it is already
8431 * These are based on patches from Minh Tran-le
8432 <mtranle@paris.intellicorp.com>.
8433 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8434 obj_format coffbfd and gas_target i386coff for target.
8435 (i[34]86-*-isc*): New host (uses sysv).
8436 * config/i386aix.mt: Removed (no longer used).
8437 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8439 (LDFLAGS): Added, defined as -shlib.
8440 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8441 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8442 (DOT_LABEL_PREFIX): Define.
8443 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8444 name rather than L0\001.
8445 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8447 * symbols.c, symbols.h (local_bss_counter): Removed.
8448 * write.c (write_object_file): bss no longer uses
8449 local_bss_counter. Pass correct data and bss size to
8450 VMS_write_object_file.

8454 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
8455 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
8456 (size_section): Restored sanity check.
8457 (do_relocs_for): Base section address on s_paddr rather than
8458 computing it. Adjust a29k R_IHIHALF special case to account for
8459 section paddr (used to require paddr to be zero). If there are no
8460 reclos, set s_relptr to 0. Set relocation size in object_headers.
8461 (fill_section): Always set s_vaddr here, removing
8462 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8463 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8464 Set STYP_INFO for .comment.
8465 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
8466 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

8468 H_{SET,GET}_* macros.
8469 (do_linenos_for): Set lineno size in object_headers.
8470 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8471 set s_vaddr here. If string_byte_count remains 4, set it back to
8472 0, and only write strings out if there are some. Call
8473 fill_section before do_relocs_for and do_linenos_for.
8474 (obj_coff_section): Handle optional quoted second argument giving
8475 section characteristics.
8476 (obj_coff_bss): Added to handle .bss.
8477 (obj_coff_ident): Added to handle .ident (puts string in .comment
8479 (obj_coff_lcomm): Put common symbols in .bss, not .data.
8480 (fixup_mdeps): Change to segment. Call frag_wane after
8482 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8483 adjustment (already happened only for common symbols, but this is
8485 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

8496 * app.c (app_push): Use memcpy, not bcopy.
8497 (do_scrub_next_char): For \", return " not '.
8498 (symbol_chars): Now const.
8500 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8501 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8503 * config/obj-coff.h: Don't use #elif.
8505 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8506 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
8508 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

8532 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8533 using ZERO_BASED_SEGMENTS.
8534 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8535 never set segment address for SEG_E2 (.bss) and don't write out
8536 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8537 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8538 definitions, and don't merge tags with non-tags. Check for .bf
8539 rather than just checking whether the second character is b and
8540 the third character is f.
8541 (obj_coff_val): gcc can generate values which we don't handle
8542 correctly; discard information for now, since it only affects the
8543 debugging information.
8544 (tag_find_or_name): Don't insert tags in the symbol table.
8545 (yank_symbols): Don't merge labels.
8546 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8552 relative addends by the segment vaddr.
8553 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
8554 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

8691 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
8692 could be doing emulation.
8694 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8697 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
8700 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
8702 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

8726 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8728 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8729 constant will not fit in an immediate field.
8730 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
8732 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

8765 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8767 * Support for i386-sysv.
8768 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8772 (fill_section): Don't set STYP_NOLOAD for .bss section.
8773 (fixup_segment): 386 uses strange common symbol format.

8787 fix i960+non-bfd coff bit rot.
8788 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
8789 support for C source listings. (obj_coff_endef): look in the right

8792 * tc-m68k.c (get_num): make it work for all segments, not just the
8795 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8797 * configure.in: recognize i386-*-bsd emulation.

8806 * tc-z8k.c: lots of bug fixes
8808 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8810 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8811 #elif, since it is not supported by old compilers.
8812 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8813 couple of expressions in tc-m68k.c.
8815 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8817 * read.c (cons): If NO_RELOC is defined, use it.
8819 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8821 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8823 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8824 local labels to start with a .) and set REGISTER_PREFIX to %.
8825 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8827 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
8829 * messages.c: Comment changes.
8831 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

8834 * messages.c: If __STDC__ is not defined, define NO_STDARG.
8836 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
8838 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8841 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8843 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8844 sections starting from zero, rather than making them consecutive.
8845 This makes subsequent reloc calculations easier, esp if the object
8846 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8847 allocate lcomm in .data rather than in .bss. It seems that some
8848 tools can't cope with a non-zero sized bss before linkage.
8850 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8852 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8853 throughout. That enum no longer means what we thought it meant.
8855 * tc-m68k.c (md_assemble, md_parse_option): Handle new
8856 "-mno-688[58]1" options.
8858 * tc-m68k.c: Added CPU32 support.
8860 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8862 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
8864 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8866 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
8867 Change LIBDEPS dependence to LIBS.
8869 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8871 * Makefile.in (install): if $(tooldir) exists, install as in
8874 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8876 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8877 .word is < -32768 or > 32767. The -J flag causes the error to be
8878 ignored. This is to catch over-sized switches generated by gcc on
8879 systems which don't support the broken .word hack.
8880 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8881 write.c (fixup_segment): check for signed .word overflow if
8882 WARN_SIGNED_OVERFLOW_WORD.
8884 * write.c (fixup_segment): fixed missing parens in expression
8885 checking for byte or word overflow.
8887 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
8888 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
8889 WARN_SIGNED_OVERFLOW_WORD.

8892 expression checking for byte or word overflow.
8894 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)

9369 machine is a SPARC or a 29K.
9370 * config/obj-aout.c: added s_sect pseudo op
9371 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9372 fill in the timestamp.

9394 * symbols.c (local_label_name): symbols now start with ^A.
9396 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9397 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9398 generate these sections. .align: will use NOP_OPCODE or 0
9399 for padding. This is just for being nice to the
9402 * expr.c (operand): changed to generate local label "\001L0"
9403 starting with a ^A so that it is recognized as a local label.
9405 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9407 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9408 i/o opcodes - inb, inw, outb and outw. string manipulation with
9409 att syntax - scmp, slod, smov, ssca, ssto.
9411 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9412 to just after .file .
9414 In obj_crawl_symbol_chain() where it tries to put the external
9415 symbols apart, with the condition:
9416 (!S_IS_DEFINED(symbolP) &&
9417 !S_IS_DEBUG(symbolP) &&
9418 !SF_GET_STATICS(symbolP))
9419 it was moving too many symbols out. So I switch it back to the
9421 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9423 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9424 so that we don't use the F_RELFLG which make the linker complain
9425 that somebody has stripped the relocation info.
9427 Also, the AIX ld program require that the relocation table
9428 is sorted by r_vaddr like the standard ATT assembler does.
9430 [he also changed the sizeof(struct ...)'s into the coff
9431 style FOOSZ macros. I'm not sure this is right, but I can't
9432 remember why. xoxorich.]

9436 * Makefile.in, configure.in, doc: use the doc. Build it, install
9439 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9441 * read.c: white space and comments only.
9443 * configure.in: use the new atof-ns32.c for ns32k.
9445 * write.c: comment change only.
9447 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9448 aren't yet integrated.
9450 * tc-i860.[hc]: blew off the dust. Something must still be done
9451 about conflicting relocation types.
9453 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9456 * tc-i960.c, tc-sparc.c: white space and comments only.
9458 * tc-a29k.h: delete duplicate macro definition.
9460 * new file atof-ns32k.c copied from hack's last unreleased gas.
9462 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9464 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9467 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9468 ChangeLog's prior to this are sketchy at best. I have logs.
9469 They just aren't ChangeLogs.
9476 version-control: never
