1014 Add a space after "pc-relative" in the error message.
1015 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1016 BFD_RELOC_386_GOTOFF relocs.

1027 referring to PLT entries.
1028 * write.c (fix_new_internal): Initialize fx_plt to zero.
1029 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
1030 Don't adjust fx_offset by frag address, since S_GET_VALUE now

1040 and after processing.
1041 (print_fixup): Added prototype. Show address on first line. Show
1042 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if
1043 NEED_FX_R_TYPE is defined.

1058 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1060 * configure.in: Set bfd_gas for all sparc targets in one place,
1061 instead of separately for each. Correctly handle user-supplied
1062 "--enable-bfd-gas" option.
1064 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1066 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

1074 (indent_level): No longer static.
1075 (print_symbol_value_1): Don't print frag address if it matches

1079 (print_expr_1): Fix whitespace before printing X_add_number.
1081 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1082 not symbol_new, for symbols holding expression values.
1083 * expr.h (make_expr_symbol): Move declaration here.
1084 * write.c (fix_new_exp): Handle O_add by creating an
1085 expression-valued symbol, and calling fix_new_exp recursively.
1086 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1087 undefined symbol and a constant, fold the constant into the fixup,
1088 and refer to the undefined symbol directly. Then process the
1089 fixup again from scratch.
1090 (write_object_file): Before calling adjust_reloc_syms, make a pass
1091 through the symbol list trying to resolve values.
1093 * write.c (print_fixup): New routine, for debugging.
1094 (write_relocs): Call bfd_install_relocation. Deleted various
1095 hacks for working around problems with bfd_perform_relocation.
1097 * Makefile.in (VERSION): Update to 2.4.90.
1099 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1103 * config/tc-mips.c: Include subsegs.h.
1104 (md_apply_fix): If an unconditional b or bal overflows, and we are
1105 not assembling PIC code, replace it with a j or jal.
1107 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1108 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

1112 * write.c (write_relocs): Add file name and line number to
1113 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1114 RELOC_EXPANSION_POSSIBLE.
1116 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1118 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1119 here. Use them for deciding which PRINTF*LIKE macro definitions
1121 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1122 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1123 default definitions matching what we were doing before.
1124 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1125 always use the varargs form if not using stdarg. It's safe to
1126 always use vfprintf, because libiberty will provide it if the
1127 native system doesn't. Also, always make format be const.
1128 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

1143 (listing_newline): Check filename as well as line number when
1144 deciding whether to record it.
1145 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1146 false (if defined) as well as checking for reg_section.
1147 (listing_listing): Iterate fetching lines while line number is too
1148 low, and we haven't run off the end of the input file.
1150 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1152 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1154 * ecoff.c (ecoff_generate_asm_lineno): check if

1161 * config/ho-*.h: Now-unused files deleted.
1163 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1164 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1165 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1166 zero. Don't call obj_frob_forward_symbol.
1167 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1168 X_add_number is zero.
1169 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1171 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1173 (strchr): Don't declare.
1174 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
1175 md_estimate_size_before_relax, md_ri_to_chars,
1176 md_create_short_jump, md_create_long_jump.
1177 (brtab_emit): Use data_section, not SEG_DATA.
1179 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1181 * config/vms-conf.h: new file, manually derived from conf.in.
1182 * config-gas.com: use it, and eliminate obsolete "host.h".

1186 * config/tc-ppc.c (ppc_current_block): New static variable.
1187 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

1191 (ppc_es): Clear ppc_current_block.
1192 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1193 from the csect of the enclosing block.
1195 * config/tc-mips.c (insns_since_cache_access): Remove.
1196 (append_insn): Remove setting of insns_since_cache_access, and
1197 special 4600 handling; it turns out not to be required.
1199 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1201 * config/tc-mips.c (md_shortopts): Remove E.
1202 (md_longopts): Add EB and EL.
1203 (md_parse_option): Handle -EB and -EL as separate options, rather
1204 than as a single -E option with an argument.

1213 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1215 * configure.in: Test for remove, not delete. Fix cross-assembler
1217 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1220 * read.c (pseudo_set, case O_symbol): If
1221 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1222 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1223 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1225 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1227 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1228 many others): new macros; values obtained from "DSTRECRDS.SDL".
1229 * config/obj-vms.h (various): use them.
1230 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1231 representation (only enum bitfields can avoid being bitstrings).
1232 (bitfield_suffix, setup_basic_type): new routines.
1233 (VMS_typedef_parse): use them. Now recognize bitfields of all
1234 integral types, not just type `int'. Caveat: the representation
1235 used for bitfields still does not work for objects placed in
1236 registers, and gcc's optimizer sometimes puts small structs there.
1238 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1240 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1241 bit from const_flag.
1242 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1243 (tc_frob_label): define this to call vms_check_for_special_label,
1244 and declare the latter.
1245 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1247 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1248 (vms_check_for_special_label): new routine (tc_frob_label).
1249 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1250 and `gcc2_compiled.' labels; they won't reach here any more.
1251 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1252 double', use `vax_g_doubles' flag to select type of double.
1253 (VMS_write_object_file) [traceback setup]: don't pass symbols
1254 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1255 and TBT_Routine_End functions.

1259 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1260 S_GET_VALUE() to avoid many repeated function calls.
1261 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1262 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1263 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1264 be obsolete; gcc does it automatically for vms target. It's
1265 also misnamed, because it is for the "VAX C" run-time library,
1266 not the newer "DEC C" one which has much different startup code.]
1267 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1268 `S_GET_xxx(symbol) = new_value'.
1270 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1272 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1273 not &bfd_abs_section.
1275 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1277 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1279 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1281 * expr.c (expr): Don't reduce the difference of two symbols in the
1282 same frag if the symbols are not in normal sections.
1284 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1285 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1286 (obj_attach_unwind_info): Do not define. Not needed anymore.
1287 * config/tc-hppa.c: Delete whitespace at EOL.
1288 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1289 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1290 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1291 fixups, store 32bits of unwind information in the fx_addnumber
1293 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1294 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1295 pointer to 32 bits of unwind info.
1296 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1297 pointer to the dummy symbol; set the addend field to fx_addnumber.
1298 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1299 rather than &bfd_XXX_section.
1301 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1303 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1304 value by one; discard adjustments previously being made. From
1307 VMS- and Vax-related changes from Pat Rankin:
1308 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1309 * vmsconf.sh: no longer have make-gas.com echo text about needing
1310 to modify the gcc-vms driver when intending to use with gcc 1.x.
1311 * as.c (parse_options): suppress 'v' from std_short_options and
1312 eliminate VMS-specific conditional initialization;
1313 [default case]: check for '-v' if md_parse_options doesn't recognize

1317 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1318 for O_big literal operands (double floats and long long ints);
1319 [VMS, md_shortopts]: add second colon after 'v';
1320 (md_parse_options) [VMS, case 'v']: check for argument, so
1321 caller can handle `-v' w/o arg.

1366 Rewrite handling of program_transform_name.
1368 * configure.in: Test for functions unlink and delete.

1374 * .gdbinit: Deleted.
1375 * aclocal.m4 (GAS_GDBINIT): Deleted.

1379 to ensure that older versions of autoconf aren't used.
1380 * Makefile.in: Added @configure_input@ line.
1381 (configure): Deleted rule.
1383 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1385 * config/obj-coff.c (fixup_segment): After handling the difference
1386 of two symbols from the same segment, set fx_subsy to NULL, to

2814 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2816 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2818 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2819 source files from other directories into objects in the current
2820 directory, and specify PSECT attributes explicitly to linker.
2821 Also added missing label.
2822 * Makefile.in (stamp-mk.com): Reference new variable
2823 VMS_OTHER_OBJS for list of non-local object files, instead of

2840 argument, the reloc type.
2841 (load_register): Pass reloc type to macro_build for 'u'.
2842 (macro): Likewise. For M_LA_AB permit a difference expression
2843 when generating embedded PIC code between an arbitrary symbol and
2844 a symbol in the .text section.

2886 (hppa_tc_symbol): Likewise.
2888 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2889 elf_tc_make_sections stuff. It was there to support PA braindamage
2890 which has been fixed, and in the case of elf_tc_make_sections is
2891 redundant with elf_tc_final_processing.

2911 don't spew remainder of input file in error message.
2912 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2913 message with reloc type and try to process remainder of file.

2925 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2926 flag rather than signedp field. Only permit extended range if
2927 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2928 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2930 * config/tc-ppc.c (ppc_size): New static variable.
2931 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2932 (md_begin): If an instruction has a size specific flag set, only
2933 add it if we are assembling that size.

2937 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2938 cross section PC relative relocs right for COFF and ELF.
2940 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2942 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

2953 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2954 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2955 and -many (all architectures).

2965 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2966 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2968 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2969 branch with an instruction that uses $at, in case the branch is
2971 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2972 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2973 to make it pcrel_offset.
2974 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2975 reloc->address; another gruesome hack to get gas reloc handling to
2978 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2980 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2983 (emit_insn): New function.
2984 (md_assemble): Call it.
2985 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2987 (lituse_pending): New variable. Set by anything that generates a
2988 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2989 tested by code that might want to emit a LITUSE reloc.
2990 (emit_unaligned_io): New function. Currently calls md_assemble,
2991 but it should eventually be converted to generate the insn itself
2992 and call emit_insn directly.
2993 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2994 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2995 emit_bis_r): Likewise.
2996 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2997 (alpha_ip, label get_macro): Don't emit the final instruction if
2999 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3000 unaligned memory access macros.
3001 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3002 the value can't be resolved.
3004 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3006 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3007 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3008 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

3020 * config/tc-mips.c (enum mips_pic_level): New enum.
3021 (mips_pic): Change from int to enum mips_pic_level. Change all
3022 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3023 (load_address): Handle EMBEDDED_PIC.
3024 (macro): Handle EMBEDDED_PIC in all PIC cases.
3025 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3026 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3027 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3028 works). Do not permit -G with SVR4_PIC.
3029 (s_abicalls): Warn if -G was used, and force -G 0.
3030 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3031 anything but a.out, not just for ELF. For ECOFF, don't generate a
3032 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3034 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3036 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3038 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3039 parameters to avoid losing when compiling with HP CC.
3040 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3042 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3044 * Makefile.in (config-stamp): If `defs' is defined, emit a
3045 preprocessor directive to create a macro named by this value into
3046 config.new; don't explicitly go for BFD_ASSEMBLER.
3047 * configure.in: Define `defs', not `BFDDEF'. Set it to
3048 MANY_SEGMENTS for any obj-coffbfd target.
3049 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3050 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3052 (LOCAL_LOADLIBES): Deleted.
3053 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3054 * config/m88kcoff.mt (TDEFINES): Ditto.
3055 * config/ebmon29k.mt: Deleted.

3080 bfd_set_symtab is called.
3081 (dump_section_relocs): Note whether a symbol is a section symbol
3083 (adjust_reloc_syms): For now, always supply an absolute symbol for
3084 fixups without symbols but not yet `done'. Use section_symbol to
3085 get the symbol, instead of going directly for abs_symbol.
3086 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3087 reloc is not a section symbol and is not in the symbol table.
3088 (set_symtab): New function, broken out from write_object_file.
3089 Counts symbol table instead of relying on an earlier count.
3090 (write_object_file): Call set_symtab, but do it after potentially
3091 invoking the *_frob_file macros. Don't bother counting symbols.
3092 Call symbol_remove, instead of expanding it in place. Moved the
3093 conditionalized `object_file_size' declaration down to
3094 conditionalized block where it's used. When using the absolute
3095 symbol for a fixup without a symbol, set sy_used_in_reloc.
3096 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3097 the correct symbol for the absolute section.
3099 * subsegs.c (section_symbol): Use symbol_new instead of
3100 symbol_make, since we may want it to go into the symbol table.
3101 Make the new symbol have internal linkage. If
3102 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3103 symbol with the newly created GAS symbol.
3104 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3105 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

3112 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3113 (sparc_ip, label "immediate"): Reject constants for pcrel
3114 instructions only if the relocation type indicates a "call"
3115 instruction and the offset is within range of a "jmpl %g0". If
3116 it's not in range, use the absolute section symbol plus an offset.
3117 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3119 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3121 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3124 * configure.in: Eliminated all targets using obj-coff but not
3125 defining BFD_ASSEMBLER; I think all such targets that are
3126 supported will be matched by real CPU-OS combinations earlier in
3128 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3129 some comments about the dpx2 configuration, but left it disabled,
3130 since it couldn't be reached before.
3131 (target a29k-amd-ebmonold): Deleted.
3133 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3141 the 'j' operand if there are no further alternatives for this
3144 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3145 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3146 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3148 * config/tc-mips.c (mips_align): Take new argument, label, and use
3149 it instead of global insn_label.
3150 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3151 call to mips_emit_delay and pass it to mips_align.
3153 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3155 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3157 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3158 argument to a .callinfo directive. Don't loop forever on errors.
3160 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3161 use pre-defined registers as arguments.

3166 S_IS_EXTERNAL when deciding whether to discard a symbol.
3168 * config-gas.com: Scan Makefile.in, not version.c, for current

3173 values to reduce number of lookups with S_GET_VALUE. Skip debug
3174 symbols to avoid "a really nasty bug". (From Holger Teutsch,
3175 holger@botbso.rhein-main.de.)
3176 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
3177 field. (Also from Holger Teutsch.) Watch for a would-be register
3178 mask that spans frags.
3180 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
3181 this_base, not line_base. (Patch from Andreas Arens,

3184 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
3185 look local if they're exported or undefined. Used to be done for
3188 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
3189 Get it from the looked-up symbol, instead of using the string from
3190 the input stream, which is no longer null-terminated.
3191 (LEX_PCT): New macro, defaults to 0.
3192 (lex_type): Use it for `%'.
3194 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

3244 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
3245 0xffff for 'j' to be compatible with MIPS assembler. These
3246 numbers are actually treated as negative.

3259 silently compiling to do nothing.
3260 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
3262 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

4829 Delete dead code. Simplify.
4830 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
4831 applied are in range. Use bfd_put_32 rather than inserting each

4910 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
4911 standard hpux include files to pick up various function decls.
4913 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

4946 of interest to the linker. ENTRY/EXIT relocations for SOM are
4947 an example of marker relocations.
4948 * write.c (write_relocs): Instead of assuming size of a relocation
4949 is 4 bytes, pick up the size from relocation itself.

4979 pass new argument for i, j and o cases.

5201 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
5202 the table, require that the one without bit 0x1000000 set come
5203 first. Require further that it be case 'b' or 'P'. The a29k
5204 opcode table already meets these constraints.
5205 (machine_ip): When handling case 'i' or 'A', make sure that the
5206 appropriate opcode really exists by looking at the next entry in

5261 * write.c (write_relocs): For relocs that are pc_relative and
5262 pcrel_offset and not partial_inplace, adjust reloc->addend to

5313 OPTIONAL_REGISTER_PREFIX if either is already defined.
5315 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5317 * configure.in: Set bfd_gas for all sparc targets. Added facility
5318 for keeping or rejecting configurations still under development;
5319 default is to assume production environment, and reject configs
5320 still being worked on. Mark Elf configurations (except sparc and
5321 i386) as developmental. Deleted cases matching some generic names
5322 in favor of more specific names. (E.g., when we get Alpha

5340 for functions only used within tc-hppa.c, likewise for structures,
5341 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5342 conditional code in a few small places.
5344 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5345 structures, global variables, forward declarations together.

5347 conditional code -- try to group conditional code together
5348 into a few places. Make all functions and variables which
5349 are only used within tc-hppa.c static. PARAMize all functions.
5350 Add comments to functions. Delete unused functions, variables,
5351 #defines, etc. Delete unused members within structures. Delete
5352 ldil;ble hacks -- it is believed they were installed to work
5353 around old gas bugs. Avoid using mixed case for local
5354 functions, variables, and structures. Fix formatting problems
5355 not found by GNU-indent. Add FIXME notices for things which
5356 should be worked on the near future. Delete lots of old
5357 useless (1.36 PA-SOM) code.

5386 a multiple of the section alignment rather than always a
5389 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5390 bits are zero (eg they specify no relocations), then do not even
5391 bother adding their entries to thesymextn section.

5435 of text, data and bss sections to 4.
5436 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5438 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5439 ELF, since the ELF object format does not have these type of
5440 relocations. Change the abort into as as_bad and return
5441 BFD_RELOC_NONE to silence compiler warnings.
5442 (md_assemble): Keep track of the instruction size. Allow white
5443 space between the $ and the constant for compatibility with older
5444 gases and other assemblers.

6519 * Extensive changes to permit symbols to contain any expression
6520 type and to delay the computation of the expression until the
6521 value is actually needed. This permits setting symbols to values
6522 calculated based on object code size. Expressions were changed to
6523 no longer be in a section, to stop the overloading of segment and
6524 expression type that previously occurred.
6526 * as.c (big_section, pass1_section, diff_section, absent_section):
6528 (expr_section): Added (used for dummy symbols which hold

6612 (previous_section, previous_subsection): New vars.
6613 (obj_elf_section): Save current place in case DWARF code wants us
6614 to pop back to it. Handle unquoted section name as well as quoted
6615 section name. Don't crash on invalid strings.
6616 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
6619 * config/obj-elf.h: Don't include struc-symbol.h.

6728 sy_resolved and sy_resolving single bit fields.
6729 * symbols.c (symbol_new): Don't initialize sy_forward field.

7877 avoid some redefinition complaints on some systems.
7878 (const, volatile): Don't need these conditionally defined if we

7880 (seg_name): Use CONST, not const.

7888 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
7889 (fixup_segment): Add a29k special case; the linker is not prepared
7890 to see a segment offset here.

7895 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7897 * Makefile.in: add dvi target; as-$(config).texinfo might live in
7898 srcdir, might be in objdir.

7928 dropping a space immediately following an identifier.
7929 * expr.c, write.c: Rewrote assert expressions to not use multiple
7930 lines; I don't think that can be done portably.

8056 * make-gas.com: Find obstack.obj if it's not in the current
8058 * read.c (s_ignore): Don't declare is_end_of_line. It's
8059 redundant, and triggers a VMS gcc compiler bug.
8061 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8062 current segment as an argument. (Ignored in all cases but VMS.)
8063 All callers and definitions changed.

8087 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8090 * configure.in: mips-bsd configuration was missing format spec.
8093 * Makefile.in (Makefile): Depends on configure.in.
8095 * config/tc-mips.c (append_insn): Don't check for alignment of
8096 frag in memory; alignment of instructions in section is a separate

8117 constants are accepted, but symbolic values are not. GCC will not
8118 generate the latter currently.
8120 * frags.c (frag_init): New function.
8121 (zero_address_frag, bss_address_frag): Now initialized at run
8123 * as.c (main): Call frag_init.

8416 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8418 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8419 will swap bytes if needed on a big endian system. Use throughout
8421 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8422 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8423 types of malformed stabs. Change parsing algorithm so that we are
8424 more certain of having all of the information that we need on hand.
8425 * obj-vms.c (final_forward_reference): New function, used to help
8426 resolve the data types of as many struct elements as possible
8427 when some part of the struct is not fully defined by the compiler.
8428 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
8430 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8431 as symbols as well in the object file. Look for external functions
8432 that start with "__vt.", and turn them into variables, since the
8433 g++ compiler is incapable of doing this.
8434 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8436 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8437 * input-scrub.c (as_where): Fix bug where as would crash if we did not

8444 SEG_DATA or SEG_E1 if needed.
8445 (s_lcomm): Likewise with bss_section.
8446 (s_fill): Use memset, not bzero.
8448 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8470 (big_section, reg_section, pass1_section, diff_section,
8471 absent_section, text_section, data_section, bss_section): If
8472 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8473 mapping to segT enum values.
8474 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8475 if these are used or defined, if BFD_ASSEMBLER.
8476 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8477 subseg_new split into two functions.
8478 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8480 * as.h (volatile): Don't define if already defined.
8481 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8483 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8484 declare with format attribute for -Wformat checking.
8486 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8488 * app.c, config/tc-*.c: Don't include read.h, since it is already
8491 * These are based on patches from Minh Tran-le
8492 <mtranle@paris.intellicorp.com>.
8493 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8494 obj_format coffbfd and gas_target i386coff for target.
8495 (i[34]86-*-isc*): New host (uses sysv).
8496 * config/i386aix.mt: Removed (no longer used).
8497 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8499 (LDFLAGS): Added, defined as -shlib.
8500 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8501 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8502 (DOT_LABEL_PREFIX): Define.
8503 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8504 name rather than L0\001.
8505 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8507 * symbols.c, symbols.h (local_bss_counter): Removed.
8508 * write.c (write_object_file): bss no longer uses

8516 (size_section): Restored sanity check.
8517 (do_relocs_for): Base section address on s_paddr rather than
8518 computing it. Adjust a29k R_IHIHALF special case to account for
8519 section paddr (used to require paddr to be zero). If there are no
8520 reclos, set s_relptr to 0. Set relocation size in object_headers.
8521 (fill_section): Always set s_vaddr here, removing
8522 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8523 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8524 Set STYP_INFO for .comment.

8528 H_{SET,GET}_* macros.
8529 (do_linenos_for): Set lineno size in object_headers.
8530 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8531 set s_vaddr here. If string_byte_count remains 4, set it back to
8532 0, and only write strings out if there are some. Call
8533 fill_section before do_relocs_for and do_linenos_for.
8534 (obj_coff_section): Handle optional quoted second argument giving
8535 section characteristics.
8536 (obj_coff_bss): Added to handle .bss.

8557 (do_scrub_next_char): For \", return " not '.
8558 (symbol_chars): Now const.
8560 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8561 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8563 * config/obj-coff.h: Don't use #elif.
8565 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8566 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8595 never set segment address for SEG_E2 (.bss) and don't write out
8596 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8597 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8598 definitions, and don't merge tags with non-tags. Check for .bf
8599 rather than just checking whether the second character is b and
8600 the third character is f.
8601 (obj_coff_val): gcc can generate values which we don't handle
8602 correctly; discard information for now, since it only affects the
8603 debugging information.

8605 (yank_symbols): Don't merge labels.
8606 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8903 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8904 sections starting from zero, rather than making them consecutive.
8905 This makes subsequent reloc calculations easier, esp if the object
8906 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8907 allocate lcomm in .data rather than in .bss. It seems that some
8908 tools can't cope with a non-zero sized bss before linkage.
8910 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8912 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8913 throughout. That enum no longer means what we thought it meant.

8934 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8936 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8937 .word is < -32768 or > 32767. The -J flag causes the error to be
8938 ignored. This is to catch over-sized switches generated by gcc on
8939 systems which don't support the broken .word hack.
8940 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8941 write.c (fixup_segment): check for signed .word overflow if
8942 WARN_SIGNED_OVERFLOW_WORD.

8971 From Steve Chamberlain:
8972 Makefile.in: Handle m68*-*-coff*.
8973 read.c, read.h: add mult argument to s_space
8975 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge

8986 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8988 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8991 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8993 * Makefile.in (LIBS): Include opcode library.

9020 * config/tc-m68k.c (init_table): Now const. Always include 68851
9021 data, so that "bc" is available to 68040 cache instructions.
9022 Added "tt0", "tt1", and 68ec030 variants.
9023 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9024 (enum _register): Added TT0, TT1.
9025 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9026 line number correctly in "internal error" messages. Don't print
9027 architecture-mismatch message for operand errors.
9029 From Colin Smith (colin@wrs.com):
9030 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

9052 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9053 has already been formatted (but may still contain %-characters).
9056 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9058 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9059 written with indirection on the last two operands, which can be
9060 either data or address registers. Added a new operand type 'r'
9061 which accepts either register type. Added '(' to notend stuff in
9062 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9391 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9393 * Makefile.in, configure.in: removed traces of namesubdir,
9394 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9395 copyrights to '92, changed some from Cygnus to FSF.
9397 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9398 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9399 copyrights to '92, changed some from Cygnus to FSF.
9401 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9403 * expr.c: If an expression is single comma, then return with
9404 SEG_ABSENT rather than an error - since the sparc front end does
9405 really strange things with things like fbge,a
9407 * as.h: include bfd.h if using many sections
9408 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9409 local labels didn't work.
9410 * listing.c (list_symbol_table): don't core dump when there's no
9412 * write.c, write.h: call fix_new with the right number of args on
9414 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9417 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9419 * app.c: MRI compatibility - allow single quote to start a string.
9420 * as.c: fix typo recently introduced.
9421 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9422 * expr.c: Much rewriting, to accomodate MRI syntax for
9423 expressions. Also easier to read now.
9424 * listing.c: Put back defuns
9425 * read.c: modified to accept MRI syntax, put back listing pseudo
9426 ops so that an assembler built with NO_LISTING ignores list ops
9428 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9429 machine is a SPARC or a 29K.
9430 * config/obj-aout.c: added s_sect pseudo op
9431 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9432 fill in the timestamp.
9433 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9434 anymore, define all the relocs which the tc-<x> bit will use so we
9435 can translate from them to the coff types.
9436 * config/tc-a29k.c: reloc_type isn't ane enum any more
9437 * config/tc-m68k.c: Added NO_RELOC definition.
9439 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9441 * Makefile.in: put header files before C source for TAGS; remove
9442 references to non-existent syscalls.h.
9444 * read.c, write.c subsegs.c: back out the .bss changes.
9446 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9448 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9452 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9454 * symbols.c (local_label_name): symbols now start with ^A.
9456 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9457 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9458 generate these sections. .align: will use NOP_OPCODE or 0
9459 for padding. This is just for being nice to the
9462 * expr.c (operand): changed to generate local label "\001L0"
9463 starting with a ^A so that it is recognized as a local label.
9465 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9467 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9468 i/o opcodes - inb, inw, outb and outw. string manipulation with
9469 att syntax - scmp, slod, smov, ssca, ssto.
9471 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9472 to just after .file .
9474 In obj_crawl_symbol_chain() where it tries to put the external
9475 symbols apart, with the condition:
9476 (!S_IS_DEFINED(symbolP) &&
9477 !S_IS_DEBUG(symbolP) &&
9478 !SF_GET_STATICS(symbolP))
9479 it was moving too many symbols out. So I switch it back to the
9481 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9483 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9484 so that we don't use the F_RELFLG which make the linker complain
9485 that somebody has stripped the relocation info.
9487 Also, the AIX ld program require that the relocation table
9488 is sorted by r_vaddr like the standard ATT assembler does.
9490 [he also changed the sizeof(struct ...)'s into the coff
9491 style FOOSZ macros. I'm not sure this is right, but I can't
9492 remember why. xoxorich.]
9494 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9496 * Makefile.in, configure.in, doc: use the doc. Build it, install
9499 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9501 * read.c: white space and comments only.
9503 * configure.in: use the new atof-ns32.c for ns32k.
9505 * write.c: comment change only.
9507 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9508 aren't yet integrated.
9510 * tc-i860.[hc]: blew off the dust. Something must still be done
9511 about conflicting relocation types.
9513 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9516 * tc-i960.c, tc-sparc.c: white space and comments only.
9518 * tc-a29k.h: delete duplicate macro definition.
9520 * new file atof-ns32k.c copied from hack's last unreleased gas.
9522 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9524 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9527 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9528 ChangeLog's prior to this are sketchy at best. I have logs.
9529 They just aren't ChangeLogs.
9536 version-control: never
