1020 Add a space after "pc-relative" in the error message.
1021 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1022 BFD_RELOC_386_GOTOFF relocs.

1064 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1066 * configure.in: Set bfd_gas for all sparc targets in one place,
1067 instead of separately for each. Correctly handle user-supplied
1068 "--enable-bfd-gas" option.
1070 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1072 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

1080 (indent_level): No longer static.
1081 (print_symbol_value_1): Don't print frag address if it matches

1085 (print_expr_1): Fix whitespace before printing X_add_number.
1087 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1088 not symbol_new, for symbols holding expression values.
1089 * expr.h (make_expr_symbol): Move declaration here.
1090 * write.c (fix_new_exp): Handle O_add by creating an
1091 expression-valued symbol, and calling fix_new_exp recursively.
1092 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1093 undefined symbol and a constant, fold the constant into the fixup,
1094 and refer to the undefined symbol directly. Then process the
1095 fixup again from scratch.
1096 (write_object_file): Before calling adjust_reloc_syms, make a pass
1097 through the symbol list trying to resolve values.
1099 * write.c (print_fixup): New routine, for debugging.
1100 (write_relocs): Call bfd_install_relocation. Deleted various
1101 hacks for working around problems with bfd_perform_relocation.
1103 * Makefile.in (VERSION): Update to 2.4.90.
1105 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1109 * config/tc-mips.c: Include subsegs.h.
1110 (md_apply_fix): If an unconditional b or bal overflows, and we are
1111 not assembling PIC code, replace it with a j or jal.
1113 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1114 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

1118 * write.c (write_relocs): Add file name and line number to
1119 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1120 RELOC_EXPANSION_POSSIBLE.
1122 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1124 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1125 here. Use them for deciding which PRINTF*LIKE macro definitions
1127 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1128 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1129 default definitions matching what we were doing before.
1130 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1131 always use the varargs form if not using stdarg. It's safe to
1132 always use vfprintf, because libiberty will provide it if the
1133 native system doesn't. Also, always make format be const.
1134 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
1136 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1149 (listing_newline): Check filename as well as line number when
1150 deciding whether to record it.
1151 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1152 false (if defined) as well as checking for reg_section.
1153 (listing_listing): Iterate fetching lines while line number is too
1154 low, and we haven't run off the end of the input file.
1156 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1158 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1160 * ecoff.c (ecoff_generate_asm_lineno): check if

1167 * config/ho-*.h: Now-unused files deleted.
1169 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1170 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1171 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1172 zero. Don't call obj_frob_forward_symbol.
1173 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1174 X_add_number is zero.
1175 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1177 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1179 (strchr): Don't declare.

1181 md_estimate_size_before_relax, md_ri_to_chars,
1182 md_create_short_jump, md_create_long_jump.
1183 (brtab_emit): Use data_section, not SEG_DATA.
1185 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1187 * config/vms-conf.h: new file, manually derived from conf.in.
1188 * config-gas.com: use it, and eliminate obsolete "host.h".

1197 (ppc_es): Clear ppc_current_block.
1198 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1199 from the csect of the enclosing block.
1201 * config/tc-mips.c (insns_since_cache_access): Remove.
1202 (append_insn): Remove setting of insns_since_cache_access, and
1203 special 4600 handling; it turns out not to be required.
1205 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1207 * config/tc-mips.c (md_shortopts): Remove E.
1208 (md_longopts): Add EB and EL.
1209 (md_parse_option): Handle -EB and -EL as separate options, rather
1210 than as a single -E option with an argument.

1219 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1221 * configure.in: Test for remove, not delete. Fix cross-assembler
1223 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1226 * read.c (pseudo_set, case O_symbol): If
1227 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1228 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1229 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1231 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1233 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1234 many others): new macros; values obtained from "DSTRECRDS.SDL".
1235 * config/obj-vms.h (various): use them.
1236 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1237 representation (only enum bitfields can avoid being bitstrings).
1238 (bitfield_suffix, setup_basic_type): new routines.
1239 (VMS_typedef_parse): use them. Now recognize bitfields of all
1240 integral types, not just type `int'. Caveat: the representation
1241 used for bitfields still does not work for objects placed in
1242 registers, and gcc's optimizer sometimes puts small structs there.
1244 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1246 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1247 bit from const_flag.
1248 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1249 (tc_frob_label): define this to call vms_check_for_special_label,
1250 and declare the latter.
1251 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1253 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1254 (vms_check_for_special_label): new routine (tc_frob_label).
1255 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1256 and `gcc2_compiled.' labels; they won't reach here any more.
1257 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1258 double', use `vax_g_doubles' flag to select type of double.
1259 (VMS_write_object_file) [traceback setup]: don't pass symbols
1260 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1261 and TBT_Routine_End functions.

1265 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1266 S_GET_VALUE() to avoid many repeated function calls.
1267 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1268 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1269 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1270 be obsolete; gcc does it automatically for vms target. It's
1271 also misnamed, because it is for the "VAX C" run-time library,
1272 not the newer "DEC C" one which has much different startup code.]
1273 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1274 `S_GET_xxx(symbol) = new_value'.
1276 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1278 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1279 not &bfd_abs_section.
1281 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1283 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1285 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1287 * expr.c (expr): Don't reduce the difference of two symbols in the
1288 same frag if the symbols are not in normal sections.
1290 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1291 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1292 (obj_attach_unwind_info): Do not define. Not needed anymore.
1293 * config/tc-hppa.c: Delete whitespace at EOL.
1294 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1295 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1296 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1297 fixups, store 32bits of unwind information in the fx_addnumber
1299 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1300 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1301 pointer to 32 bits of unwind info.
1302 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1303 pointer to the dummy symbol; set the addend field to fx_addnumber.
1304 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1305 rather than &bfd_XXX_section.
1307 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1309 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1310 value by one; discard adjustments previously being made. From
1313 VMS- and Vax-related changes from Pat Rankin:
1314 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1315 * vmsconf.sh: no longer have make-gas.com echo text about needing
1316 to modify the gcc-vms driver when intending to use with gcc 1.x.
1317 * as.c (parse_options): suppress 'v' from std_short_options and
1318 eliminate VMS-specific conditional initialization;
1319 [default case]: check for '-v' if md_parse_options doesn't recognize

1323 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1324 for O_big literal operands (double floats and long long ints);
1325 [VMS, md_shortopts]: add second colon after 'v';
1326 (md_parse_options) [VMS, case 'v']: check for argument, so
1327 caller can handle `-v' w/o arg.

1331 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET
1332 is defined, put the tx_offset into the r_offset.

1372 Rewrite handling of program_transform_name.
1374 * configure.in: Test for functions unlink and delete.

1380 * .gdbinit: Deleted.
1381 * aclocal.m4 (GAS_GDBINIT): Deleted.

1385 to ensure that older versions of autoconf aren't used.
1386 * Makefile.in: Added @configure_input@ line.
1387 (configure): Deleted rule.
1389 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1391 * config/obj-coff.c (fixup_segment): After handling the difference
1392 of two symbols from the same segment, set fx_subsy to NULL, to

2820 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2822 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2824 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2825 source files from other directories into objects in the current
2826 directory, and specify PSECT attributes explicitly to linker.
2827 Also added missing label.

2846 argument, the reloc type.
2847 (load_register): Pass reloc type to macro_build for 'u'.
2848 (macro): Likewise. For M_LA_AB permit a difference expression
2849 when generating embedded PIC code between an arbitrary symbol and
2850 a symbol in the .text section.
2851 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2852 BFD_RELOC_PCREL_LO16 to be emitted.

2860 * subsegs.c (subsegs_begin): Call memset with args in the correct
2862 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2863 to NULL instead of 0.

2892 (hppa_tc_symbol): Likewise.
2894 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2895 elf_tc_make_sections stuff. It was there to support PA braindamage
2896 which has been fixed, and in the case of elf_tc_make_sections is
2897 redundant with elf_tc_final_processing.
2899 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2917 don't spew remainder of input file in error message.
2918 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2919 message with reloc type and try to process remainder of file.

2931 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2932 flag rather than signedp field. Only permit extended range if
2933 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2934 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2936 * config/tc-ppc.c (ppc_size): New static variable.
2937 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2938 (md_begin): If an instruction has a size specific flag set, only
2939 add it if we are assembling that size.
2941 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2943 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2944 cross section PC relative relocs right for COFF and ELF.
2946 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2948 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

2953 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2954 the type of symbol set symbols which happen to be in the absolute
2955 or undefined section.

2959 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2960 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2961 and -many (all architectures).

2971 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2972 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2974 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2975 branch with an instruction that uses $at, in case the branch is
2977 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2978 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2979 to make it pcrel_offset.
2980 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2981 reloc->address; another gruesome hack to get gas reloc handling to
2984 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2986 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2989 (emit_insn): New function.
2990 (md_assemble): Call it.
2991 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2993 (lituse_pending): New variable. Set by anything that generates a
2994 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2995 tested by code that might want to emit a LITUSE reloc.
2996 (emit_unaligned_io): New function. Currently calls md_assemble,
2997 but it should eventually be converted to generate the insn itself
2998 and call emit_insn directly.
2999 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3000 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3001 emit_bis_r): Likewise.
3002 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3003 (alpha_ip, label get_macro): Don't emit the final instruction if
3005 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3006 unaligned memory access macros.
3007 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3008 the value can't be resolved.
3010 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3012 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3013 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3014 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3016 (mips_force_relocation): New function.
3017 (md_apply_fix): Set fixP->fx_done appropriately.

3026 * config/tc-mips.c (enum mips_pic_level): New enum.
3027 (mips_pic): Change from int to enum mips_pic_level. Change all
3028 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3029 (load_address): Handle EMBEDDED_PIC.
3030 (macro): Handle EMBEDDED_PIC in all PIC cases.
3031 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3032 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3033 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3034 works). Do not permit -G with SVR4_PIC.
3035 (s_abicalls): Warn if -G was used, and force -G 0.
3036 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3037 anything but a.out, not just for ELF. For ECOFF, don't generate a
3038 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3040 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3042 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3044 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3045 parameters to avoid losing when compiling with HP CC.
3046 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3048 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3050 * Makefile.in (config-stamp): If `defs' is defined, emit a
3051 preprocessor directive to create a macro named by this value into
3052 config.new; don't explicitly go for BFD_ASSEMBLER.
3053 * configure.in: Define `defs', not `BFDDEF'. Set it to
3054 MANY_SEGMENTS for any obj-coffbfd target.
3055 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3056 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3058 (LOCAL_LOADLIBES): Deleted.
3059 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3060 * config/m88kcoff.mt (TDEFINES): Ditto.
3061 * config/ebmon29k.mt: Deleted.
3062 * config/h8300hds.mt: Deleted.

3086 bfd_set_symtab is called.
3087 (dump_section_relocs): Note whether a symbol is a section symbol
3089 (adjust_reloc_syms): For now, always supply an absolute symbol for
3090 fixups without symbols but not yet `done'. Use section_symbol to
3091 get the symbol, instead of going directly for abs_symbol.
3092 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3093 reloc is not a section symbol and is not in the symbol table.
3094 (set_symtab): New function, broken out from write_object_file.
3095 Counts symbol table instead of relying on an earlier count.
3096 (write_object_file): Call set_symtab, but do it after potentially
3097 invoking the *_frob_file macros. Don't bother counting symbols.
3098 Call symbol_remove, instead of expanding it in place. Moved the
3099 conditionalized `object_file_size' declaration down to
3100 conditionalized block where it's used. When using the absolute
3101 symbol for a fixup without a symbol, set sy_used_in_reloc.
3102 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3103 the correct symbol for the absolute section.
3105 * subsegs.c (section_symbol): Use symbol_new instead of
3106 symbol_make, since we may want it to go into the symbol table.
3107 Make the new symbol have internal linkage. If
3108 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3109 symbol with the newly created GAS symbol.
3110 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3111 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

3116 (in_signed_range): New function.
3118 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3119 (sparc_ip, label "immediate"): Reject constants for pcrel
3120 instructions only if the relocation type indicates a "call"
3121 instruction and the offset is within range of a "jmpl %g0". If
3122 it's not in range, use the absolute section symbol plus an offset.
3123 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3125 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3127 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3130 * configure.in: Eliminated all targets using obj-coff but not
3131 defining BFD_ASSEMBLER; I think all such targets that are
3132 supported will be matched by real CPU-OS combinations earlier in
3134 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3135 some comments about the dpx2 configuration, but left it disabled,
3136 since it couldn't be reached before.
3137 (target a29k-amd-ebmonold): Deleted.
3139 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3147 the 'j' operand if there are no further alternatives for this
3150 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3151 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3152 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3154 * config/tc-mips.c (mips_align): Take new argument, label, and use
3155 it instead of global insn_label.
3156 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3157 call to mips_emit_delay and pass it to mips_align.
3159 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3161 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3163 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3164 argument to a .callinfo directive. Don't loop forever on errors.
3166 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3167 use pre-defined registers as arguments.

3172 S_IS_EXTERNAL when deciding whether to discard a symbol.
3174 * config-gas.com: Scan Makefile.in, not version.c, for current

3176 with them. Create config.h.
3178 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
3179 values to reduce number of lookups with S_GET_VALUE. Skip debug
3180 symbols to avoid "a really nasty bug". (From Holger Teutsch,
3181 holger@botbso.rhein-main.de.)
3182 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
3183 field. (Also from Holger Teutsch.) Watch for a would-be register
3184 mask that spans frags.
3186 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
3187 this_base, not line_base. (Patch from Andreas Arens,

3190 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
3191 look local if they're exported or undefined. Used to be done for
3194 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
3195 Get it from the looked-up symbol, instead of using the string from
3196 the input stream, which is no longer null-terminated.
3197 (LEX_PCT): New macro, defaults to 0.
3198 (lex_type): Use it for `%'.
3200 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
3201 (vip_op): Now static, and returns void. Callers changed. Added

3250 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
3251 0xffff for 'j' to be compatible with MIPS assembler. These
3252 numbers are actually treated as negative.

3263 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this
3264 work. It still doesn't. It now fails to compile, instead of
3265 silently compiling to do nothing.
3266 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
3268 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

4835 Delete dead code. Simplify.
4836 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
4837 applied are in range. Use bfd_put_32 rather than inserting each

4916 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
4917 standard hpux include files to pick up various function decls.
4919 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

4952 of interest to the linker. ENTRY/EXIT relocations for SOM are
4953 an example of marker relocations.
4954 * write.c (write_relocs): Instead of assuming size of a relocation
4955 is 4 bytes, pick up the size from relocation itself.

4985 pass new argument for i, j and o cases.
4986 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

5207 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
5208 the table, require that the one without bit 0x1000000 set come
5209 first. Require further that it be case 'b' or 'P'. The a29k
5210 opcode table already meets these constraints.
5211 (machine_ip): When handling case 'i' or 'A', make sure that the
5212 appropriate opcode really exists by looking at the next entry in

5267 * write.c (write_relocs): For relocs that are pc_relative and
5268 pcrel_offset and not partial_inplace, adjust reloc->addend to

5319 OPTIONAL_REGISTER_PREFIX if either is already defined.
5321 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5323 * configure.in: Set bfd_gas for all sparc targets. Added facility
5324 for keeping or rejecting configurations still under development;
5325 default is to assume production environment, and reject configs
5326 still being worked on. Mark Elf configurations (except sparc and
5327 i386) as developmental. Deleted cases matching some generic names
5328 in favor of more specific names. (E.g., when we get Alpha

5346 for functions only used within tc-hppa.c, likewise for structures,
5347 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5348 conditional code in a few small places.
5350 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5351 structures, global variables, forward declarations together.

5353 conditional code -- try to group conditional code together
5354 into a few places. Make all functions and variables which
5355 are only used within tc-hppa.c static. PARAMize all functions.
5356 Add comments to functions. Delete unused functions, variables,
5357 #defines, etc. Delete unused members within structures. Delete
5358 ldil;ble hacks -- it is believed they were installed to work
5359 around old gas bugs. Avoid using mixed case for local
5360 functions, variables, and structures. Fix formatting problems
5361 not found by GNU-indent. Add FIXME notices for things which
5362 should be worked on the near future. Delete lots of old
5363 useless (1.36 PA-SOM) code.
5365 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type

5392 a multiple of the section alignment rather than always a
5395 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5396 bits are zero (eg they specify no relocations), then do not even
5397 bother adding their entries to thesymextn section.

5441 of text, data and bss sections to 4.
5442 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5444 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5445 ELF, since the ELF object format does not have these type of
5446 relocations. Change the abort into as as_bad and return
5447 BFD_RELOC_NONE to silence compiler warnings.
5448 (md_assemble): Keep track of the instruction size. Allow white
5449 space between the $ and the constant for compatibility with older
5450 gases and other assemblers.

6525 * Extensive changes to permit symbols to contain any expression
6526 type and to delay the computation of the expression until the
6527 value is actually needed. This permits setting symbols to values
6528 calculated based on object code size. Expressions were changed to
6529 no longer be in a section, to stop the overloading of segment and
6530 expression type that previously occurred.
6532 * as.c (big_section, pass1_section, diff_section, absent_section):
6534 (expr_section): Added (used for dummy symbols which hold

6618 (previous_section, previous_subsection): New vars.
6619 (obj_elf_section): Save current place in case DWARF code wants us
6620 to pop back to it. Handle unquoted section name as well as quoted
6621 section name. Don't crash on invalid strings.
6622 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
6625 * config/obj-elf.h: Don't include struc-symbol.h.

6734 sy_resolved and sy_resolving single bit fields.
6735 * symbols.c (symbol_new): Don't initialize sy_forward field.

7934 dropping a space immediately following an identifier.
7935 * expr.c, write.c: Rewrote assert expressions to not use multiple
7936 lines; I don't think that can be done portably.
7937 * config/tc-mips.c (macro): Use $AT if target register is zero in
7938 load instruction, which it can be for a floating point load.

8012 prototypes for all static functions. Moved existing minimal
8013 debugging format support info #ifndef OBJ_ECOFF blocks.

8062 * make-gas.com: Find obstack.obj if it's not in the current
8064 * read.c (s_ignore): Don't declare is_end_of_line. It's
8065 redundant, and triggers a VMS gcc compiler bug.
8067 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8068 current segment as an argument. (Ignored in all cases but VMS.)
8069 All callers and definitions changed.

8093 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8096 * configure.in: mips-bsd configuration was missing format spec.
8099 * Makefile.in (Makefile): Depends on configure.in.
8101 * config/tc-mips.c (append_insn): Don't check for alignment of
8102 frag in memory; alignment of instructions in section is a separate

8123 constants are accepted, but symbolic values are not. GCC will not
8124 generate the latter currently.
8126 * frags.c (frag_init): New function.
8127 (zero_address_frag, bss_address_frag): Now initialized at run
8129 * as.c (main): Call frag_init.

8419 * config-gas.com: New file. Script for VMS systems to set up the
8420 configuration to build gas for VMS, and create config.status.
8421 * make-gas.com: Redone to work with new scheme.
8422 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8424 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8425 will swap bytes if needed on a big endian system. Use throughout
8427 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8428 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8429 types of malformed stabs. Change parsing algorithm so that we are
8430 more certain of having all of the information that we need on hand.
8431 * obj-vms.c (final_forward_reference): New function, used to help
8432 resolve the data types of as many struct elements as possible
8433 when some part of the struct is not fully defined by the compiler.
8434 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
8436 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8437 as symbols as well in the object file. Look for external functions
8438 that start with "__vt.", and turn them into variables, since the
8439 g++ compiler is incapable of doing this.
8440 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8442 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8443 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8444 have the name of the source file yet.

8450 SEG_DATA or SEG_E1 if needed.
8451 (s_lcomm): Likewise with bss_section.
8452 (s_fill): Use memset, not bzero.
8454 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8478 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8479 mapping to segT enum values.
8480 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8481 if these are used or defined, if BFD_ASSEMBLER.
8482 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8483 subseg_new split into two functions.
8484 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8486 * as.h (volatile): Don't define if already defined.
8487 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8489 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8490 declare with format attribute for -Wformat checking.
8492 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8494 * app.c, config/tc-*.c: Don't include read.h, since it is already
8497 * These are based on patches from Minh Tran-le
8498 <mtranle@paris.intellicorp.com>.
8499 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8500 obj_format coffbfd and gas_target i386coff for target.
8501 (i[34]86-*-isc*): New host (uses sysv).
8502 * config/i386aix.mt: Removed (no longer used).
8503 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8505 (LDFLAGS): Added, defined as -shlib.
8506 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8507 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8508 (DOT_LABEL_PREFIX): Define.
8509 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8510 name rather than L0\001.
8511 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8513 * symbols.c, symbols.h (local_bss_counter): Removed.

8522 (size_section): Restored sanity check.
8523 (do_relocs_for): Base section address on s_paddr rather than
8524 computing it. Adjust a29k R_IHIHALF special case to account for
8525 section paddr (used to require paddr to be zero). If there are no
8526 reclos, set s_relptr to 0. Set relocation size in object_headers.
8527 (fill_section): Always set s_vaddr here, removing
8528 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8529 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8530 Set STYP_INFO for .comment.

8534 H_{SET,GET}_* macros.
8535 (do_linenos_for): Set lineno size in object_headers.
8536 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8537 set s_vaddr here. If string_byte_count remains 4, set it back to
8538 0, and only write strings out if there are some. Call
8539 fill_section before do_relocs_for and do_linenos_for.
8540 (obj_coff_section): Handle optional quoted second argument giving
8541 section characteristics.
8542 (obj_coff_bss): Added to handle .bss.

8564 (symbol_chars): Now const.
8566 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8567 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8569 * config/obj-coff.h: Don't use #elif.
8571 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8572 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8601 never set segment address for SEG_E2 (.bss) and don't write out
8602 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8603 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8604 definitions, and don't merge tags with non-tags. Check for .bf
8605 rather than just checking whether the second character is b and
8606 the third character is f.
8607 (obj_coff_val): gcc can generate values which we don't handle
8608 correctly; discard information for now, since it only affects the
8609 debugging information.

8611 (yank_symbols): Don't merge labels.
8612 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8909 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8910 sections starting from zero, rather than making them consecutive.
8911 This makes subsequent reloc calculations easier, esp if the object
8912 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8913 allocate lcomm in .data rather than in .bss. It seems that some
8914 tools can't cope with a non-zero sized bss before linkage.
8916 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8918 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8942 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8943 .word is < -32768 or > 32767. The -J flag causes the error to be
8944 ignored. This is to catch over-sized switches generated by gcc on
8945 systems which don't support the broken .word hack.
8946 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8947 write.c (fixup_segment): check for signed .word overflow if
8948 WARN_SIGNED_OVERFLOW_WORD.

8977 From Steve Chamberlain:
8978 Makefile.in: Handle m68*-*-coff*.
8979 read.c, read.h: add mult argument to s_space
8981 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge

8991 (fixup_segment) set fx_subsy to 0.
8992 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8994 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8997 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

9026 * config/tc-m68k.c (init_table): Now const. Always include 68851
9027 data, so that "bc" is available to 68040 cache instructions.
9028 Added "tt0", "tt1", and 68ec030 variants.
9029 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9030 (enum _register): Added TT0, TT1.
9031 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9032 line number correctly in "internal error" messages. Don't print
9033 architecture-mismatch message for operand errors.

9058 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9059 has already been formatted (but may still contain %-characters).
9062 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9064 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9065 written with indirection on the last two operands, which can be
9066 either data or address registers. Added a new operand type 'r'
9067 which accepts either register type. Added '(' to notend stuff in
9068 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9392 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9394 * expr.c (operand): if can't work out what sort of operand it is,
9395 then look through FLT_CHARS for a hint.
9397 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9399 * Makefile.in, configure.in: removed traces of namesubdir,
9400 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9401 copyrights to '92, changed some from Cygnus to FSF.
9403 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9404 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9405 copyrights to '92, changed some from Cygnus to FSF.
9407 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9409 * expr.c: If an expression is single comma, then return with
9410 SEG_ABSENT rather than an error - since the sparc front end does
9411 really strange things with things like fbge,a
9413 * as.h: include bfd.h if using many sections
9414 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9415 local labels didn't work.
9416 * listing.c (list_symbol_table): don't core dump when there's no
9418 * write.c, write.h: call fix_new with the right number of args on
9420 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9423 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9425 * app.c: MRI compatibility - allow single quote to start a string.
9426 * as.c: fix typo recently introduced.
9427 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9428 * expr.c: Much rewriting, to accomodate MRI syntax for
9429 expressions. Also easier to read now.
9430 * listing.c: Put back defuns
9431 * read.c: modified to accept MRI syntax, put back listing pseudo
9432 ops so that an assembler built with NO_LISTING ignores list ops
9434 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9435 machine is a SPARC or a 29K.
9436 * config/obj-aout.c: added s_sect pseudo op
9437 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9438 fill in the timestamp.
9439 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9440 anymore, define all the relocs which the tc-<x> bit will use so we
9441 can translate from them to the coff types.
9442 * config/tc-a29k.c: reloc_type isn't ane enum any more
9443 * config/tc-m68k.c: Added NO_RELOC definition.
9445 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9447 * Makefile.in: put header files before C source for TAGS; remove
9448 references to non-existent syscalls.h.
9450 * read.c, write.c subsegs.c: back out the .bss changes.
9452 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9454 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9458 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9460 * symbols.c (local_label_name): symbols now start with ^A.
9462 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9463 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9464 generate these sections. .align: will use NOP_OPCODE or 0
9465 for padding. This is just for being nice to the
9468 * expr.c (operand): changed to generate local label "\001L0"
9469 starting with a ^A so that it is recognized as a local label.
9471 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9473 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9474 i/o opcodes - inb, inw, outb and outw. string manipulation with
9475 att syntax - scmp, slod, smov, ssca, ssto.
9477 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9478 to just after .file .
9480 In obj_crawl_symbol_chain() where it tries to put the external
9481 symbols apart, with the condition:
9482 (!S_IS_DEFINED(symbolP) &&
9483 !S_IS_DEBUG(symbolP) &&
9484 !SF_GET_STATICS(symbolP))
9485 it was moving too many symbols out. So I switch it back to the
9487 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9489 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9490 so that we don't use the F_RELFLG which make the linker complain
9491 that somebody has stripped the relocation info.
9493 Also, the AIX ld program require that the relocation table
9494 is sorted by r_vaddr like the standard ATT assembler does.
9496 [he also changed the sizeof(struct ...)'s into the coff
9497 style FOOSZ macros. I'm not sure this is right, but I can't
9498 remember why. xoxorich.]
9500 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9502 * Makefile.in, configure.in, doc: use the doc. Build it, install
9505 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9507 * read.c: white space and comments only.
9509 * configure.in: use the new atof-ns32.c for ns32k.
9511 * write.c: comment change only.
9513 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9514 aren't yet integrated.
9516 * tc-i860.[hc]: blew off the dust. Something must still be done
9517 about conflicting relocation types.
9519 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9522 * tc-i960.c, tc-sparc.c: white space and comments only.
9524 * tc-a29k.h: delete duplicate macro definition.
9526 * new file atof-ns32k.c copied from hack's last unreleased gas.
9528 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9530 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9533 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9534 ChangeLog's prior to this are sketchy at best. I have logs.
9535 They just aren't ChangeLogs.
9542 version-control: never
