994 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
995 processing if add_symbol is undefined or in expr_section.
996 (resolve_symbol_value, case O_add): For symbol plus
997 constant-valued symbol, convert to O_symbol and re-reduce.

999 (indent_level): No longer static.
1000 (print_symbol_value_1): Don't print frag address if it matches
1001 zero_address_frag. Don't print "resolving" if already resolved.

1004 (print_expr_1): Fix whitespace before printing X_add_number.
1006 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1007 not symbol_new, for symbols holding expression values.
1008 * expr.h (make_expr_symbol): Move declaration here.
1009 * write.c (fix_new_exp): Handle O_add by creating an
1010 expression-valued symbol, and calling fix_new_exp recursively.
1011 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1012 undefined symbol and a constant, fold the constant into the fixup,
1013 and refer to the undefined symbol directly. Then process the
1014 fixup again from scratch.
1015 (write_object_file): Before calling adjust_reloc_syms, make a pass
1016 through the symbol list trying to resolve values.
1018 * write.c (print_fixup): New routine, for debugging.
1019 (write_relocs): Call bfd_install_relocation. Deleted various
1020 hacks for working around problems with bfd_perform_relocation.
1022 * Makefile.in (VERSION): Update to 2.4.90.

1028 * config/tc-mips.c: Include subsegs.h.
1029 (md_apply_fix): If an unconditional b or bal overflows, and we are
1030 not assembling PIC code, replace it with a j or jal.
1032 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1033 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

1037 * write.c (write_relocs): Add file name and line number to
1038 as_fatal calls. Handle bfd_reloc_overflow case specifically when

1041 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1043 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1044 here. Use them for deciding which PRINTF*LIKE macro definitions
1046 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1047 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1048 default definitions matching what we were doing before.
1049 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1050 always use the varargs form if not using stdarg. It's safe to
1051 always use vfprintf, because libiberty will provide it if the
1052 native system doesn't. Also, always make format be const.
1053 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

1069 deciding whether to record it.
1070 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1071 false (if defined) as well as checking for reg_section.
1072 (listing_listing): Iterate fetching lines while line number is too
1073 low, and we haven't run off the end of the input file.
1075 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1077 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1079 * ecoff.c (ecoff_generate_asm_lineno): check if
1080 current_stabs_filename is NULL before strcmp.
1081 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
1084 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1086 * config/ho-*.h: Now-unused files deleted.
1088 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1089 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1090 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1091 zero. Don't call obj_frob_forward_symbol.
1092 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1093 X_add_number is zero.
1094 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1096 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1098 (strchr): Don't declare.
1099 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
1100 md_estimate_size_before_relax, md_ri_to_chars,
1101 md_create_short_jump, md_create_long_jump.
1102 (brtab_emit): Use data_section, not SEG_DATA.
1104 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1106 * config/vms-conf.h: new file, manually derived from conf.in.
1107 * config-gas.com: use it, and eliminate obsolete "host.h".

1111 * config/tc-ppc.c (ppc_current_block): New static variable.
1112 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

1116 (ppc_es): Clear ppc_current_block.
1117 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1118 from the csect of the enclosing block.
1120 * config/tc-mips.c (insns_since_cache_access): Remove.
1121 (append_insn): Remove setting of insns_since_cache_access, and
1122 special 4600 handling; it turns out not to be required.
1124 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1126 * config/tc-mips.c (md_shortopts): Remove E.
1127 (md_longopts): Add EB and EL.
1128 (md_parse_option): Handle -EB and -EL as separate options, rather
1129 than as a single -E option with an argument.

1138 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1140 * configure.in: Test for remove, not delete. Fix cross-assembler
1142 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1145 * read.c (pseudo_set, case O_symbol): If
1146 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1147 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1148 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1150 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1152 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1153 many others): new macros; values obtained from "DSTRECRDS.SDL".
1154 * config/obj-vms.h (various): use them.
1155 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1156 representation (only enum bitfields can avoid being bitstrings).
1157 (bitfield_suffix, setup_basic_type): new routines.
1158 (VMS_typedef_parse): use them. Now recognize bitfields of all
1159 integral types, not just type `int'. Caveat: the representation
1160 used for bitfields still does not work for objects placed in
1161 registers, and gcc's optimizer sometimes puts small structs there.
1163 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1165 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1166 bit from const_flag.
1167 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1168 (tc_frob_label): define this to call vms_check_for_special_label,
1169 and declare the latter.
1170 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1172 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1173 (vms_check_for_special_label): new routine (tc_frob_label).
1174 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1175 and `gcc2_compiled.' labels; they won't reach here any more.
1176 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1177 double', use `vax_g_doubles' flag to select type of double.
1178 (VMS_write_object_file) [traceback setup]: don't pass symbols
1179 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1180 and TBT_Routine_End functions.

1184 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1185 S_GET_VALUE() to avoid many repeated function calls.
1186 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1187 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1188 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1189 be obsolete; gcc does it automatically for vms target. It's
1190 also misnamed, because it is for the "VAX C" run-time library,
1191 not the newer "DEC C" one which has much different startup code.]
1192 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1193 `S_GET_xxx(symbol) = new_value'.
1195 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1197 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1198 not &bfd_abs_section.
1200 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1202 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1204 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1206 * expr.c (expr): Don't reduce the difference of two symbols in the
1207 same frag if the symbols are not in normal sections.
1209 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1210 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1211 (obj_attach_unwind_info): Do not define. Not needed anymore.
1212 * config/tc-hppa.c: Delete whitespace at EOL.
1213 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1214 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1215 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1216 fixups, store 32bits of unwind information in the fx_addnumber
1218 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1219 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1220 pointer to 32 bits of unwind info.
1221 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1222 pointer to the dummy symbol; set the addend field to fx_addnumber.
1223 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1224 rather than &bfd_XXX_section.
1226 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1228 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1229 value by one; discard adjustments previously being made. From
1232 VMS- and Vax-related changes from Pat Rankin:
1233 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1234 * vmsconf.sh: no longer have make-gas.com echo text about needing
1235 to modify the gcc-vms driver when intending to use with gcc 1.x.
1236 * as.c (parse_options): suppress 'v' from std_short_options and
1237 eliminate VMS-specific conditional initialization;
1238 [default case]: check for '-v' if md_parse_options doesn't recognize
1240 [default case, #if VMS]: check for filename argument when '-v' seen;
1242 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1243 for O_big literal operands (double floats and long long ints);
1244 [VMS, md_shortopts]: add second colon after 'v';
1245 (md_parse_options) [VMS, case 'v']: check for argument, so
1246 caller can handle `-v' w/o arg.

1390 (s_mips_globl): New static function; needed for Irix 5 support.
1391 * ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
1392 external symbol with no type, set the type to st_Proc rather than

2367 new VMS symbol-type macros; signed and unsigned quadword integers,
2368 for `long long' support. Their values come from the existing

2370 VMS debugger now recognizes `long long' variables correctly.
2371 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
2372 for gcc2's predefined types "long double" (same as double, as
2373 per gcc's current state), "long long int", "long long unsigned
2374 int", and final `otherwise' case (to avoid uninitialized type
2375 and size fields). [caveat: predefined types "complex int",
2376 "complex float", "complex double", and "complex long double" are
2379 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
2380 of 0, because the latter indicates success rather than failure

2744 source files from other directories into objects in the current
2745 directory, and specify PSECT attributes explicitly to linker.
2746 Also added missing label.

2835 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
2836 don't spew remainder of input file in error message.
2837 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2838 message with reloc type and try to process remainder of file.
2840 * doc/Makefile.in (install-info-as, install-info-gasp): New
2841 targets, now explicitly checking $(srcdir) for info files.
2842 (install-info): Depend on both of them; do nothing more.

2850 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2851 flag rather than signedp field. Only permit extended range if
2852 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2853 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2855 * config/tc-ppc.c (ppc_size): New static variable.
2856 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2857 (md_begin): If an instruction has a size specific flag set, only
2858 add it if we are assembling that size.
2860 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2862 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2863 cross section PC relative relocs right for COFF and ELF.
2865 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2867 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

2872 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2873 the type of symbol set symbols which happen to be in the absolute
2874 or undefined section.

2878 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2879 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2880 and -many (all architectures).
2882 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2891 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2893 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2894 branch with an instruction that uses $at, in case the branch is
2896 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2897 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2898 to make it pcrel_offset.
2899 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2900 reloc->address; another gruesome hack to get gas reloc handling to
2903 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2905 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2908 (emit_insn): New function.
2909 (md_assemble): Call it.
2910 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2912 (lituse_pending): New variable. Set by anything that generates a
2913 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2914 tested by code that might want to emit a LITUSE reloc.
2915 (emit_unaligned_io): New function. Currently calls md_assemble,
2916 but it should eventually be converted to generate the insn itself
2917 and call emit_insn directly.
2918 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2919 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2920 emit_bis_r): Likewise.

2924 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2925 unaligned memory access macros.
2926 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2927 the value can't be resolved.
2929 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2931 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2932 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2933 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2935 (mips_force_relocation): New function.
2936 (md_apply_fix): Set fixP->fx_done appropriately.
2937 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2945 * config/tc-mips.c (enum mips_pic_level): New enum.
2946 (mips_pic): Change from int to enum mips_pic_level. Change all
2947 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2948 (load_address): Handle EMBEDDED_PIC.
2949 (macro): Handle EMBEDDED_PIC in all PIC cases.
2950 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2951 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2952 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2953 works). Do not permit -G with SVR4_PIC.
2954 (s_abicalls): Warn if -G was used, and force -G 0.
2955 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2956 anything but a.out, not just for ELF. For ECOFF, don't generate a
2957 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2959 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2961 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2963 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2964 parameters to avoid losing when compiling with HP CC.
2965 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2967 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2969 * Makefile.in (config-stamp): If `defs' is defined, emit a
2970 preprocessor directive to create a macro named by this value into
2971 config.new; don't explicitly go for BFD_ASSEMBLER.
2972 * configure.in: Define `defs', not `BFDDEF'. Set it to
2973 MANY_SEGMENTS for any obj-coffbfd target.
2974 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2975 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2977 (LOCAL_LOADLIBES): Deleted.
2978 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2979 * config/m88kcoff.mt (TDEFINES): Ditto.
2980 * config/ebmon29k.mt: Deleted.
2981 * config/h8300hds.mt: Deleted.

2983 * config/sparc.mt: Deleted.
2984 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2985 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2986 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

3005 bfd_set_symtab is called.
3006 (dump_section_relocs): Note whether a symbol is a section symbol
3008 (adjust_reloc_syms): For now, always supply an absolute symbol for
3009 fixups without symbols but not yet `done'. Use section_symbol to
3010 get the symbol, instead of going directly for abs_symbol.
3011 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3012 reloc is not a section symbol and is not in the symbol table.
3013 (set_symtab): New function, broken out from write_object_file.
3014 Counts symbol table instead of relying on an earlier count.
3015 (write_object_file): Call set_symtab, but do it after potentially
3016 invoking the *_frob_file macros. Don't bother counting symbols.
3017 Call symbol_remove, instead of expanding it in place. Moved the
3018 conditionalized `object_file_size' declaration down to
3019 conditionalized block where it's used. When using the absolute
3020 symbol for a fixup without a symbol, set sy_used_in_reloc.
3021 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3022 the correct symbol for the absolute section.
3024 * subsegs.c (section_symbol): Use symbol_new instead of
3025 symbol_make, since we may want it to go into the symbol table.
3026 Make the new symbol have internal linkage. If
3027 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3028 symbol with the newly created GAS symbol.
3029 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3030 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

3035 (in_signed_range): New function.
3037 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3038 (sparc_ip, label "immediate"): Reject constants for pcrel
3039 instructions only if the relocation type indicates a "call"
3040 instruction and the offset is within range of a "jmpl %g0". If
3041 it's not in range, use the absolute section symbol plus an offset.
3042 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3044 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3046 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3049 * configure.in: Eliminated all targets using obj-coff but not
3050 defining BFD_ASSEMBLER; I think all such targets that are
3051 supported will be matched by real CPU-OS combinations earlier in
3053 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3054 some comments about the dpx2 configuration, but left it disabled,
3055 since it couldn't be reached before.
3056 (target a29k-amd-ebmonold): Deleted.
3058 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3066 the 'j' operand if there are no further alternatives for this
3069 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3070 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3071 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3073 * config/tc-mips.c (mips_align): Take new argument, label, and use
3074 it instead of global insn_label.
3075 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3076 call to mips_emit_delay and pass it to mips_align.
3078 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3080 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3082 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3083 argument to a .callinfo directive. Don't loop forever on errors.
3085 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3086 use pre-defined registers as arguments.

3090 * write.c (write_object_file): Check both S_IS_LOCAL and
3091 S_IS_EXTERNAL when deciding whether to discard a symbol.
3093 * config-gas.com: Scan Makefile.in, not version.c, for current
3094 version number. Delete all versions of temp files when finished
3095 with them. Create config.h.
3097 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
3098 values to reduce number of lookups with S_GET_VALUE. Skip debug
3099 symbols to avoid "a really nasty bug". (From Holger Teutsch,
3100 holger@botbso.rhein-main.de.)
3101 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
3102 field. (Also from Holger Teutsch.) Watch for a would-be register
3103 mask that spans frags.
3105 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
3106 this_base, not line_base. (Patch from Andreas Arens,
3107 ari@obelix.av.rwth-aachen.de.)
3109 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
3110 look local if they're exported or undefined. Used to be done for
3113 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
3114 Get it from the looked-up symbol, instead of using the string from
3115 the input stream, which is no longer null-terminated.
3116 (LEX_PCT): New macro, defaults to 0.
3117 (lex_type): Use it for `%'.
3119 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
3120 (vip_op): Now static, and returns void. Callers changed. Added
3122 (vip): Ditto. Call as_fatal directly if a program bug is

3169 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
3170 0xffff for 'j' to be compatible with MIPS assembler. These

3256 BFD_ASSEMBLER is defined.
3257 (mem_fmt): Since COFF doesn't handle callx relocations yet, treat
3258 them like normal 32-bit relocations.

3260 (tc_bout_fix_to_chars): Store symbol index for all callx
3261 relocations, regardless of link-relax setting.

5244 default is to assume production environment, and reject configs
5245 still being worked on. Mark Elf configurations (except sparc and
5246 i386) as developmental. Deleted cases matching some generic names
5247 in favor of more specific names. (E.g., when we get Alpha

5273 into a few places. Make all functions and variables which
5274 are only used within tc-hppa.c static. PARAMize all functions.
5275 Add comments to functions. Delete unused functions, variables,
5276 #defines, etc. Delete unused members within structures. Delete
5277 ldil;ble hacks -- it is believed they were installed to work
5278 around old gas bugs. Avoid using mixed case for local
5279 functions, variables, and structures. Fix formatting problems
5280 not found by GNU-indent. Add FIXME notices for things which
5281 should be worked on the near future. Delete lots of old
5282 useless (1.36 PA-SOM) code.

5302 of elf32_symbol_type.
5303 (pa_export_args): Likewise.

5311 a multiple of the section alignment rather than always a
5314 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5315 bits are zero (eg they specify no relocations), then do not even
5316 bother adding their entries to thesymextn section.

5361 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5363 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5364 ELF, since the ELF object format does not have these type of
5365 relocations. Change the abort into as as_bad and return
5366 BFD_RELOC_NONE to silence compiler warnings.
5367 (md_assemble): Keep track of the instruction size. Allow white
5368 space between the $ and the constant for compatibility with older
5369 gases and other assemblers.

7813 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7853 dropping a space immediately following an identifier.

7855 lines; I don't think that can be done portably.
7856 * config/tc-mips.c (macro): Use $AT if target register is zero in

7981 * make-gas.com: Find obstack.obj if it's not in the current
7983 * read.c (s_ignore): Don't declare is_end_of_line. It's
7984 redundant, and triggers a VMS gcc compiler bug.
7986 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7987 current segment as an argument. (Ignored in all cases but VMS.)
7988 All callers and definitions changed.

8041 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8042 constants are accepted, but symbolic values are not. GCC will not
8043 generate the latter currently.
8045 * frags.c (frag_init): New function.
8046 (zero_address_frag, bss_address_frag): Now initialized at run
8048 * as.c (main): Call frag_init.

8319 (operand): Treat zero byte as end-of-operand.
8321 * configure.in (per-target): Look for with_bfd_assembler option.
8322 For now, only accept "no", until the merge is done.
8324 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8325 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

8331 * expr.c: Add "const" modifier to hex_value.
8332 * symbols.c: Finish conversion to S_* macros in the VMS only
8333 parts of the program. Add "const" modifier to
8334 md_[long,short]_jump_size. Remove declaration of const_flag
8335 (which will be declared in obj-vms.h).
8336 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8337 Fix arguments to VMS_write_object_file.
8338 * config-gas.com: New file. Script for VMS systems to set up the

8347 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8348 types of malformed stabs. Change parsing algorithm so that we are
8349 more certain of having all of the information that we need on hand.

8397 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8398 mapping to segT enum values.
8399 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8400 if these are used or defined, if BFD_ASSEMBLER.
8401 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8402 subseg_new split into two functions.
8403 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8405 * as.h (volatile): Don't define if already defined.
8406 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8408 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8409 declare with format attribute for -Wformat checking.

8413 * app.c, config/tc-*.c: Don't include read.h, since it is already
8416 * These are based on patches from Minh Tran-le
8417 <mtranle@paris.intellicorp.com>.
8418 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8419 obj_format coffbfd and gas_target i386coff for target.
8420 (i[34]86-*-isc*): New host (uses sysv).
8421 * config/i386aix.mt: Removed (no longer used).
8422 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8424 (LDFLAGS): Added, defined as -shlib.
8425 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8426 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8427 (DOT_LABEL_PREFIX): Define.
8428 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8429 name rather than L0\001.
8430 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8432 * symbols.c, symbols.h (local_bss_counter): Removed.
8433 * write.c (write_object_file): bss no longer uses
8434 local_bss_counter. Pass correct data and bss size to
8435 VMS_write_object_file.
8436 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
8437 argument, rather than using local_bss_counter.

8439 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
8440 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
8441 (size_section): Restored sanity check.
8442 (do_relocs_for): Base section address on s_paddr rather than
8443 computing it. Adjust a29k R_IHIHALF special case to account for
8444 section paddr (used to require paddr to be zero). If there are no
8445 reclos, set s_relptr to 0. Set relocation size in object_headers.
8446 (fill_section): Always set s_vaddr here, removing
8447 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8448 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8449 Set STYP_INFO for .comment.
8450 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
8451 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

8453 H_{SET,GET}_* macros.
8454 (do_linenos_for): Set lineno size in object_headers.
8455 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8456 set s_vaddr here. If string_byte_count remains 4, set it back to
8457 0, and only write strings out if there are some. Call
8458 fill_section before do_relocs_for and do_linenos_for.
8459 (obj_coff_section): Handle optional quoted second argument giving
8460 section characteristics.
8461 (obj_coff_bss): Added to handle .bss.
8462 (obj_coff_ident): Added to handle .ident (puts string in .comment
8464 (obj_coff_lcomm): Put common symbols in .bss, not .data.
8465 (fixup_mdeps): Change to segment. Call frag_wane after
8467 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8468 adjustment (already happened only for common symbols, but this is
8470 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8471 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8481 * app.c (app_push): Use memcpy, not bcopy.
8482 (do_scrub_next_char): For \", return " not '.
8483 (symbol_chars): Now const.
8485 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8486 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8488 * config/obj-coff.h: Don't use #elif.
8490 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8491 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8517 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8518 using ZERO_BASED_SEGMENTS.
8519 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8520 never set segment address for SEG_E2 (.bss) and don't write out
8521 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8522 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8523 definitions, and don't merge tags with non-tags. Check for .bf
8524 rather than just checking whether the second character is b and
8525 the third character is f.
8526 (obj_coff_val): gcc can generate values which we don't handle
8527 correctly; discard information for now, since it only affects the
8528 debugging information.
8529 (tag_find_or_name): Don't insert tags in the symbol table.
8530 (yank_symbols): Don't merge labels.
8531 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8534 (obj_coff_section): Accept and ignore a trailing quoted string, as
8535 used in AT&T i386 syntax.
8536 (fixup_segment): Take segment as argument. On the i386, adjust PC
8537 relative addends by the segment vaddr.
8538 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
8539 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

8676 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
8677 could be doing emulation.
8679 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8682 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
8685 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

8711 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8713 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8714 constant will not fit in an immediate field.
8715 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
8717 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

8750 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8752 * Support for i386-sysv.
8753 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8757 (fill_section): Don't set STYP_NOLOAD for .bss section.
8758 (fixup_segment): 386 uses strange common symbol format.

8777 * tc-m68k.c (get_num): make it work for all segments, not just the
8780 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8782 * configure.in: recognize i386-*-bsd emulation.

8791 * tc-z8k.c: lots of bug fixes
8793 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8795 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8796 #elif, since it is not supported by old compilers.
8797 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8798 couple of expressions in tc-m68k.c.
8800 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8802 * read.c (cons): If NO_RELOC is defined, use it.
8804 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8806 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8808 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8809 local labels to start with a .) and set REGISTER_PREFIX to %.
8810 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8812 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
8814 * messages.c: Comment changes.
8816 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

8819 * messages.c: If __STDC__ is not defined, define NO_STDARG.
8821 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
8823 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8826 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8828 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8829 sections starting from zero, rather than making them consecutive.
8830 This makes subsequent reloc calculations easier, esp if the object
8831 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8832 allocate lcomm in .data rather than in .bss. It seems that some
8833 tools can't cope with a non-zero sized bss before linkage.
8835 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8837 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8838 throughout. That enum no longer means what we thought it meant.
8840 * tc-m68k.c (md_assemble, md_parse_option): Handle new
8841 "-mno-688[58]1" options.
8843 * tc-m68k.c: Added CPU32 support.
8845 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

8849 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8851 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
8852 Change LIBDEPS dependence to LIBS.
8854 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8856 * Makefile.in (install): if $(tooldir) exists, install as in
8859 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8861 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8862 .word is < -32768 or > 32767. The -J flag causes the error to be
8863 ignored. This is to catch over-sized switches generated by gcc on
8864 systems which don't support the broken .word hack.
8865 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8866 write.c (fixup_segment): check for signed .word overflow if
8867 WARN_SIGNED_OVERFLOW_WORD.
8869 * write.c (fixup_segment): fixed missing parens in expression
8870 checking for byte or word overflow.
8872 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

8884 * tc-i386.h : new coff defines
8886 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8888 * input-scrub.c (input_scrub_push): call input_file_begin, not
8890 messages.c (as_perror): print ": " between the passed in error and
8891 the strerror, like perror does.
8893 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
8895 * Makefile.in: use gas_target instead of modifying target_cpu.
8896 From Steve Chamberlain:
8897 Makefile.in: Handle m68*-*-coff*.

8983 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8984 written with indirection on the last two operands, which can be
8985 either data or address registers. Added a new operand type 'r'
8986 which accepts either register type. Added '(' to notend stuff in
8987 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9330 really strange things with things like fbge,a
9332 * as.h: include bfd.h if using many sections
9333 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

9348 expressions. Also easier to read now.
9349 * listing.c: Put back defuns
9350 * read.c: modified to accept MRI syntax, put back listing pseudo
9351 ops so that an assembler built with NO_LISTING ignores list ops
9353 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9354 machine is a SPARC or a 29K.
9355 * config/obj-aout.c: added s_sect pseudo op
9356 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9357 fill in the timestamp.
9358 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9359 anymore, define all the relocs which the tc-<x> bit will use so we
9360 can translate from them to the coff types.
9361 * config/tc-a29k.c: reloc_type isn't ane enum any more
9362 * config/tc-m68k.c: Added NO_RELOC definition.

9381 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9382 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9383 generate these sections. .align: will use NOP_OPCODE or 0
9384 for padding. This is just for being nice to the
9387 * expr.c (operand): changed to generate local label "\001L0"
9388 starting with a ^A so that it is recognized as a local label.
9390 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9392 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9393 i/o opcodes - inb, inw, outb and outw. string manipulation with
9394 att syntax - scmp, slod, smov, ssca, ssto.
9396 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9397 to just after .file .
9399 In obj_crawl_symbol_chain() where it tries to put the external
9400 symbols apart, with the condition:
9401 (!S_IS_DEFINED(symbolP) &&
9402 !S_IS_DEBUG(symbolP) &&
9403 !SF_GET_STATICS(symbolP))
9404 it was moving too many symbols out. So I switch it back to the
9406 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9408 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9409 so that we don't use the F_RELFLG which make the linker complain
9410 that somebody has stripped the relocation info.
9412 Also, the AIX ld program require that the relocation table
9413 is sorted by r_vaddr like the standard ATT assembler does.
9415 [he also changed the sizeof(struct ...)'s into the coff
9416 style FOOSZ macros. I'm not sure this is right, but I can't
9417 remember why. xoxorich.]

9421 * Makefile.in, configure.in, doc: use the doc. Build it, install
9424 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9426 * read.c: white space and comments only.
9428 * configure.in: use the new atof-ns32.c for ns32k.
9430 * write.c: comment change only.
9432 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9433 aren't yet integrated.
9435 * tc-i860.[hc]: blew off the dust. Something must still be done
9436 about conflicting relocation types.
9438 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9441 * tc-i960.c, tc-sparc.c: white space and comments only.
9443 * tc-a29k.h: delete duplicate macro definition.
9445 * new file atof-ns32k.c copied from hack's last unreleased gas.

9449 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9452 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9453 ChangeLog's prior to this are sketchy at best. I have logs.
9454 They just aren't ChangeLogs.
