985 (diststuff): New target; builds DISTSTUFF.
986 (realclean): Separate target, depend on clean and distclean, then
988 * make-gas.com: Deleted.
990 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
991 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
993 (i386_operand): Don't look up section symbol for

1002 (TC_VALIDATE_FIX): New macro -- call it.
1003 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.
1005 * as.h: If __STDC__ is not defined and varargs.h is available, use

1009 referring to PLT entries.
1010 * write.c (fix_new_internal): Initialize fx_plt to zero.
1011 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
1012 Don't adjust fx_offset by frag address, since S_GET_VALUE now
1013 includes the frag address.
1014 (fixup_segment): Changed local var PCREL to type int, added PLT.
1015 If PC-relative fixup refers to a PLT entry for a symbol in the
1016 current section, don't reduce it.

1019 DEBUG5 is defined, print out each fixup before and after
1021 (fixup_segment): If DEBUG5 is defined, print out each fixup before
1022 and after processing.
1023 (print_fixup): Added prototype. Show address on first line. Show
1024 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if
1025 NEED_FX_R_TYPE is defined.

1040 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1042 * configure.in: Set bfd_gas for all sparc targets in one place,
1043 instead of separately for each. Correctly handle user-supplied
1044 "--enable-bfd-gas" option.
1046 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1048 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

1056 (indent_level): No longer static.
1057 (print_symbol_value_1): Don't print frag address if it matches

1061 (print_expr_1): Fix whitespace before printing X_add_number.
1063 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1064 not symbol_new, for symbols holding expression values.
1065 * expr.h (make_expr_symbol): Move declaration here.
1066 * write.c (fix_new_exp): Handle O_add by creating an
1067 expression-valued symbol, and calling fix_new_exp recursively.
1068 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1069 undefined symbol and a constant, fold the constant into the fixup,
1070 and refer to the undefined symbol directly. Then process the
1071 fixup again from scratch.
1072 (write_object_file): Before calling adjust_reloc_syms, make a pass
1073 through the symbol list trying to resolve values.
1075 * write.c (print_fixup): New routine, for debugging.
1076 (write_relocs): Call bfd_install_relocation. Deleted various
1077 hacks for working around problems with bfd_perform_relocation.
1079 * Makefile.in (VERSION): Update to 2.4.90.

1085 * config/tc-mips.c: Include subsegs.h.
1086 (md_apply_fix): If an unconditional b or bal overflows, and we are
1087 not assembling PIC code, replace it with a j or jal.
1089 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1090 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

1094 * write.c (write_relocs): Add file name and line number to
1095 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1096 RELOC_EXPANSION_POSSIBLE.
1098 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1100 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1101 here. Use them for deciding which PRINTF*LIKE macro definitions
1103 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1104 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1105 default definitions matching what we were doing before.
1106 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1107 always use the varargs form if not using stdarg. It's safe to
1108 always use vfprintf, because libiberty will provide it if the
1109 native system doesn't. Also, always make format be const.
1110 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

1125 (listing_newline): Check filename as well as line number when
1126 deciding whether to record it.
1127 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1128 false (if defined) as well as checking for reg_section.
1129 (listing_listing): Iterate fetching lines while line number is too
1130 low, and we haven't run off the end of the input file.
1132 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1134 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1136 * ecoff.c (ecoff_generate_asm_lineno): check if

1143 * config/ho-*.h: Now-unused files deleted.
1145 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1146 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1147 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1148 zero. Don't call obj_frob_forward_symbol.
1149 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1150 X_add_number is zero.
1151 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1153 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1155 (strchr): Don't declare.

1157 md_estimate_size_before_relax, md_ri_to_chars,
1158 md_create_short_jump, md_create_long_jump.
1159 (brtab_emit): Use data_section, not SEG_DATA.
1161 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1163 * config/vms-conf.h: new file, manually derived from conf.in.
1164 * config-gas.com: use it, and eliminate obsolete "host.h".

1173 (ppc_es): Clear ppc_current_block.
1174 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1175 from the csect of the enclosing block.
1177 * config/tc-mips.c (insns_since_cache_access): Remove.
1178 (append_insn): Remove setting of insns_since_cache_access, and
1179 special 4600 handling; it turns out not to be required.
1181 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1183 * config/tc-mips.c (md_shortopts): Remove E.
1184 (md_longopts): Add EB and EL.
1185 (md_parse_option): Handle -EB and -EL as separate options, rather
1186 than as a single -E option with an argument.

1195 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1197 * configure.in: Test for remove, not delete. Fix cross-assembler
1199 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to

1203 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1204 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1205 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1207 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1209 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1210 many others): new macros; values obtained from "DSTRECRDS.SDL".
1211 * config/obj-vms.h (various): use them.
1212 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1213 representation (only enum bitfields can avoid being bitstrings).
1214 (bitfield_suffix, setup_basic_type): new routines.
1215 (VMS_typedef_parse): use them. Now recognize bitfields of all
1216 integral types, not just type `int'. Caveat: the representation
1217 used for bitfields still does not work for objects placed in
1218 registers, and gcc's optimizer sometimes puts small structs there.
1220 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1222 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1223 bit from const_flag.
1224 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

1226 and declare the latter.
1227 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1229 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1230 (vms_check_for_special_label): new routine (tc_frob_label).
1231 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1232 and `gcc2_compiled.' labels; they won't reach here any more.
1233 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1234 double', use `vax_g_doubles' flag to select type of double.
1235 (VMS_write_object_file) [traceback setup]: don't pass symbols
1236 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1237 and TBT_Routine_End functions.

1241 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1242 S_GET_VALUE() to avoid many repeated function calls.
1243 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1244 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1245 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1246 be obsolete; gcc does it automatically for vms target. It's
1247 also misnamed, because it is for the "VAX C" run-time library,
1248 not the newer "DEC C" one which has much different startup code.]
1249 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1250 `S_GET_xxx(symbol) = new_value'.
1252 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1254 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1255 not &bfd_abs_section.
1257 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1259 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1261 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1263 * expr.c (expr): Don't reduce the difference of two symbols in the
1264 same frag if the symbols are not in normal sections.
1266 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1267 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1268 (obj_attach_unwind_info): Do not define. Not needed anymore.
1269 * config/tc-hppa.c: Delete whitespace at EOL.
1270 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1271 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1272 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1273 fixups, store 32bits of unwind information in the fx_addnumber
1275 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1276 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1277 pointer to 32 bits of unwind info.
1278 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1279 pointer to the dummy symbol; set the addend field to fx_addnumber.
1280 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1281 rather than &bfd_XXX_section.
1283 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1285 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1286 value by one; discard adjustments previously being made. From
1289 VMS- and Vax-related changes from Pat Rankin:
1290 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1291 * vmsconf.sh: no longer have make-gas.com echo text about needing
1292 to modify the gcc-vms driver when intending to use with gcc 1.x.
1293 * as.c (parse_options): suppress 'v' from std_short_options and
1294 eliminate VMS-specific conditional initialization;
1295 [default case]: check for '-v' if md_parse_options doesn't recognize
1297 [default case, #if VMS]: check for filename argument when '-v' seen;
1299 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1300 for O_big literal operands (double floats and long long ints);
1301 [VMS, md_shortopts]: add second colon after 'v';
1302 (md_parse_options) [VMS, case 'v']: check for argument, so
1303 caller can handle `-v' w/o arg.

1348 Rewrite handling of program_transform_name.
1350 * configure.in: Test for functions unlink and delete.

1356 * .gdbinit: Deleted.
1357 * aclocal.m4 (GAS_GDBINIT): Deleted.

1361 to ensure that older versions of autoconf aren't used.
1362 * Makefile.in: Added @configure_input@ line.
1363 (configure): Deleted rule.
1365 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1367 * config/obj-coff.c (fixup_segment): After handling the difference
1368 of two symbols from the same segment, set fx_subsy to NULL, to

1413 fixup is not local, to prevent relocations against externals from
1415 (md_assemble): Initialize disp_reloc field to NO_RELOC. Pass
1416 disp_reloc field to reloc() function, and use TC_RELOC to generate

2374 * config/tc-alpha.c (machine): New variable.
2375 (load_insn): New macro.
2376 (load_insn_table): New function.
2377 (md_begin): Call load_insn_table, once for basic instructions and

2399 * Makefile.in (VERSION): Updated to cygnus-2.3.1.
2401 * config/obj-vms.c: Replaced unchecked uses of malloc with
2404 * listing.c (list_symbol_table): Only test BFD64, not
2407 * config/obj-coff.c (fixup_segment) [BFD_ASSEMBLER]

2427 VMS debugger now recognizes `long long' variables correctly.
2428 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
2429 for gcc2's predefined types "long double" (same as double, as
2430 per gcc's current state), "long long int", "long long unsigned
2431 int", and final `otherwise' case (to avoid uninitialized type
2432 and size fields). [caveat: predefined types "complex int",
2433 "complex float", "complex double", and "complex long double" are
2436 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
2437 of 0, because the latter indicates success rather than failure

2796 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2798 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2800 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2801 source files from other directories into objects in the current
2802 directory, and specify PSECT attributes explicitly to linker.
2803 Also added missing label.
2804 * Makefile.in (stamp-mk.com): Reference new variable

2868 (hppa_tc_symbol): Likewise.
2870 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2871 elf_tc_make_sections stuff. It was there to support PA braindamage
2872 which has been fixed, and in the case of elf_tc_make_sections is
2873 redundant with elf_tc_final_processing.

2893 don't spew remainder of input file in error message.
2894 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2895 message with reloc type and try to process remainder of file.

2907 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2908 flag rather than signedp field. Only permit extended range if
2909 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2910 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2912 * config/tc-ppc.c (ppc_size): New static variable.
2913 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2914 (md_begin): If an instruction has a size specific flag set, only
2915 add it if we are assembling that size.

2919 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2920 cross section PC relative relocs right for COFF and ELF.
2922 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2924 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

2947 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2948 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2950 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2951 branch with an instruction that uses $at, in case the branch is
2953 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2954 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2955 to make it pcrel_offset.
2956 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2957 reloc->address; another gruesome hack to get gas reloc handling to
2960 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2962 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2965 (emit_insn): New function.
2966 (md_assemble): Call it.
2967 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2969 (lituse_pending): New variable. Set by anything that generates a
2970 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2971 tested by code that might want to emit a LITUSE reloc.
2972 (emit_unaligned_io): New function. Currently calls md_assemble,
2973 but it should eventually be converted to generate the insn itself
2974 and call emit_insn directly.
2975 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2976 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2977 emit_bis_r): Likewise.
2978 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2979 (alpha_ip, label get_macro): Don't emit the final instruction if
2981 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2982 unaligned memory access macros.

2986 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2988 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2989 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2990 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

3002 * config/tc-mips.c (enum mips_pic_level): New enum.
3003 (mips_pic): Change from int to enum mips_pic_level. Change all
3004 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3005 (load_address): Handle EMBEDDED_PIC.
3006 (macro): Handle EMBEDDED_PIC in all PIC cases.
3007 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3008 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3009 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3010 works). Do not permit -G with SVR4_PIC.
3011 (s_abicalls): Warn if -G was used, and force -G 0.
3012 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3013 anything but a.out, not just for ELF. For ECOFF, don't generate a
3014 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3016 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3018 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3020 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3021 parameters to avoid losing when compiling with HP CC.
3022 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3024 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3026 * Makefile.in (config-stamp): If `defs' is defined, emit a
3027 preprocessor directive to create a macro named by this value into
3028 config.new; don't explicitly go for BFD_ASSEMBLER.
3029 * configure.in: Define `defs', not `BFDDEF'. Set it to
3030 MANY_SEGMENTS for any obj-coffbfd target.
3031 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3032 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3034 (LOCAL_LOADLIBES): Deleted.
3035 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3036 * config/m88kcoff.mt (TDEFINES): Ditto.
3037 * config/ebmon29k.mt: Deleted.

3062 bfd_set_symtab is called.
3063 (dump_section_relocs): Note whether a symbol is a section symbol
3065 (adjust_reloc_syms): For now, always supply an absolute symbol for
3066 fixups without symbols but not yet `done'. Use section_symbol to
3067 get the symbol, instead of going directly for abs_symbol.
3068 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3069 reloc is not a section symbol and is not in the symbol table.
3070 (set_symtab): New function, broken out from write_object_file.
3071 Counts symbol table instead of relying on an earlier count.
3072 (write_object_file): Call set_symtab, but do it after potentially
3073 invoking the *_frob_file macros. Don't bother counting symbols.
3074 Call symbol_remove, instead of expanding it in place. Moved the
3075 conditionalized `object_file_size' declaration down to
3076 conditionalized block where it's used. When using the absolute
3077 symbol for a fixup without a symbol, set sy_used_in_reloc.
3078 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3079 the correct symbol for the absolute section.
3081 * subsegs.c (section_symbol): Use symbol_new instead of
3082 symbol_make, since we may want it to go into the symbol table.
3083 Make the new symbol have internal linkage. If
3084 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3085 symbol with the newly created GAS symbol.
3086 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3087 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

3094 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3095 (sparc_ip, label "immediate"): Reject constants for pcrel
3096 instructions only if the relocation type indicates a "call"
3097 instruction and the offset is within range of a "jmpl %g0". If
3098 it's not in range, use the absolute section symbol plus an offset.
3099 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3101 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3103 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3106 * configure.in: Eliminated all targets using obj-coff but not
3107 defining BFD_ASSEMBLER; I think all such targets that are
3108 supported will be matched by real CPU-OS combinations earlier in
3110 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3111 some comments about the dpx2 configuration, but left it disabled,
3112 since it couldn't be reached before.
3113 (target a29k-amd-ebmonold): Deleted.
3115 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3123 the 'j' operand if there are no further alternatives for this
3126 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3127 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3128 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3130 * config/tc-mips.c (mips_align): Take new argument, label, and use
3131 it instead of global insn_label.
3132 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3133 call to mips_emit_delay and pass it to mips_align.
3135 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3137 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3139 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3140 argument to a .callinfo directive. Don't loop forever on errors.
3142 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3143 use pre-defined registers as arguments.

3148 S_IS_EXTERNAL when deciding whether to discard a symbol.
3150 * config-gas.com: Scan Makefile.in, not version.c, for current
3151 version number. Delete all versions of temp files when finished
3152 with them. Create config.h.
3154 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
3155 values to reduce number of lookups with S_GET_VALUE. Skip debug
3156 symbols to avoid "a really nasty bug". (From Holger Teutsch,
3157 holger@botbso.rhein-main.de.)
3158 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
3159 field. (Also from Holger Teutsch.) Watch for a would-be register
3160 mask that spans frags.
3162 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
3163 this_base, not line_base. (Patch from Andreas Arens,
3164 ari@obelix.av.rwth-aachen.de.)
3166 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
3167 look local if they're exported or undefined. Used to be done for
3170 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
3171 Get it from the looked-up symbol, instead of using the string from
3172 the input stream, which is no longer null-terminated.
3173 (LEX_PCT): New macro, defaults to 0.
3174 (lex_type): Use it for `%'.
3176 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
3177 (vip_op): Now static, and returns void. Callers changed. Added

3226 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
3227 0xffff for 'j' to be compatible with MIPS assembler. These
3228 numbers are actually treated as negative.

3244 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

4811 Delete dead code. Simplify.
4812 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
4813 applied are in range. Use bfd_put_32 rather than inserting each

5183 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
5184 the table, require that the one without bit 0x1000000 set come
5185 first. Require further that it be case 'b' or 'P'. The a29k
5186 opcode table already meets these constraints.
5187 (machine_ip): When handling case 'i' or 'A', make sure that the
5188 appropriate opcode really exists by looking at the next entry in

5243 * write.c (write_relocs): For relocs that are pc_relative and
5244 pcrel_offset and not partial_inplace, adjust reloc->addend to

5295 OPTIONAL_REGISTER_PREFIX if either is already defined.
5297 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5299 * configure.in: Set bfd_gas for all sparc targets. Added facility
5300 for keeping or rejecting configurations still under development;
5301 default is to assume production environment, and reject configs
5302 still being worked on. Mark Elf configurations (except sparc and
5303 i386) as developmental. Deleted cases matching some generic names
5304 in favor of more specific names. (E.g., when we get Alpha

5322 for functions only used within tc-hppa.c, likewise for structures,
5323 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5324 conditional code in a few small places.
5326 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5327 structures, global variables, forward declarations together.

5329 conditional code -- try to group conditional code together
5330 into a few places. Make all functions and variables which
5331 are only used within tc-hppa.c static. PARAMize all functions.
5332 Add comments to functions. Delete unused functions, variables,
5333 #defines, etc. Delete unused members within structures. Delete
5334 ldil;ble hacks -- it is believed they were installed to work
5335 around old gas bugs. Avoid using mixed case for local
5336 functions, variables, and structures. Fix formatting problems
5337 not found by GNU-indent. Add FIXME notices for things which
5338 should be worked on the near future. Delete lots of old
5339 useless (1.36 PA-SOM) code.

5368 a multiple of the section alignment rather than always a
5371 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5372 bits are zero (eg they specify no relocations), then do not even
5373 bother adding their entries to thesymextn section.

5417 of text, data and bss sections to 4.
5418 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5420 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5421 ELF, since the ELF object format does not have these type of
5422 relocations. Change the abort into as as_bad and return
5423 BFD_RELOC_NONE to silence compiler warnings.
5424 (md_assemble): Keep track of the instruction size. Allow white
5425 space between the $ and the constant for compatibility with older
5426 gases and other assemblers.
5427 (i386_operand): Skip spaces between $ and expression.

7870 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7877 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7879 * Makefile.in: add dvi target; as-$(config).texinfo might live in

7910 dropping a space immediately following an identifier.

7912 lines; I don't think that can be done portably.
7913 * config/tc-mips.c (macro): Use $AT if target register is zero in

8040 * read.c (s_ignore): Don't declare is_end_of_line. It's
8041 redundant, and triggers a VMS gcc compiler bug.
8043 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8044 current segment as an argument. (Ignored in all cases but VMS.)
8045 All callers and definitions changed.

8415 g++ compiler is incapable of doing this.
8416 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8418 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8419 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8420 have the name of the source file yet.
8421 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8423 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8425 * read.c (s_data): Always use "data_section", since it'll map to
8426 SEG_DATA or SEG_E1 if needed.
8427 (s_lcomm): Likewise with bss_section.
8428 (s_fill): Use memset, not bzero.
8430 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
8432 * read.c: Deleted some code under "#ifdef DONTDEF" that was for
8433 handling GDB symbol table data.
8435 * config/obj-aout.h (segment_name): Delete definition.
8436 (seg_name): Delete declaration.

8438 * config/obj-vms.h (segment_name, seg_name): Ditto.
8439 * config/obj-coff.h (segment_name): Ditto.
8440 * config/obj-coffbfd.h (segment_name): Ditto.
8442 * Changes for BFD_ASSEMBLER:
8443 * obj.h (obj_crawl_symbol_chain): Declare only if not
8445 (obj_header_append, obj_pre_write_hook): Ditto.
8446 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
8447 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
8448 (segment_name) If BFD_ASSEMBLER, look up BFD section name;
8449 otherwise, use seg_name array.

8451 (section_alignment): Declare only if not BFD_ASSEMBLER.
8452 (big_section, reg_section, pass1_section, diff_section,
8453 absent_section, text_section, data_section, bss_section): If
8454 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8455 mapping to segT enum values.
8456 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8457 if these are used or defined, if BFD_ASSEMBLER.
8458 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8459 subseg_new split into two functions.
8460 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8462 * as.h (volatile): Don't define if already defined.
8463 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8465 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8466 declare with format attribute for -Wformat checking.
8468 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8470 * app.c, config/tc-*.c: Don't include read.h, since it is already
8473 * These are based on patches from Minh Tran-le
8474 <mtranle@paris.intellicorp.com>.
8475 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8476 obj_format coffbfd and gas_target i386coff for target.
8477 (i[34]86-*-isc*): New host (uses sysv).
8478 * config/i386aix.mt: Removed (no longer used).
8479 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8481 (LDFLAGS): Added, defined as -shlib.
8482 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8483 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8484 (DOT_LABEL_PREFIX): Define.
8485 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8486 name rather than L0\001.
8487 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8489 * symbols.c, symbols.h (local_bss_counter): Removed.
8490 * write.c (write_object_file): bss no longer uses
8491 local_bss_counter. Pass correct data and bss size to
8492 VMS_write_object_file.

8497 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
8498 (size_section): Restored sanity check.
8499 (do_relocs_for): Base section address on s_paddr rather than
8500 computing it. Adjust a29k R_IHIHALF special case to account for
8501 section paddr (used to require paddr to be zero). If there are no
8502 reclos, set s_relptr to 0. Set relocation size in object_headers.
8503 (fill_section): Always set s_vaddr here, removing
8504 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8505 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8506 Set STYP_INFO for .comment.
8507 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
8508 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
8509 (crawl_symbols): Handle 8 character section name correctly. Use
8510 H_{SET,GET}_* macros.
8511 (do_linenos_for): Set lineno size in object_headers.
8512 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8513 set s_vaddr here. If string_byte_count remains 4, set it back to
8514 0, and only write strings out if there are some. Call
8515 fill_section before do_relocs_for and do_linenos_for.
8516 (obj_coff_section): Handle optional quoted second argument giving
8517 section characteristics.
8518 (obj_coff_bss): Added to handle .bss.
8519 (obj_coff_ident): Added to handle .ident (puts string in .comment
8521 (obj_coff_lcomm): Put common symbols in .bss, not .data.
8522 (fixup_mdeps): Change to segment. Call frag_wane after
8524 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8525 adjustment (already happened only for common symbols, but this is
8527 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8528 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8539 (do_scrub_next_char): For \", return " not '.
8540 (symbol_chars): Now const.
8542 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8543 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8545 * config/obj-coff.h: Don't use #elif.
8547 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8548 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
8550 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

8574 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8575 using ZERO_BASED_SEGMENTS.
8576 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8577 never set segment address for SEG_E2 (.bss) and don't write out
8578 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8579 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8580 definitions, and don't merge tags with non-tags. Check for .bf
8581 rather than just checking whether the second character is b and
8582 the third character is f.
8583 (obj_coff_val): gcc can generate values which we don't handle
8584 correctly; discard information for now, since it only affects the
8585 debugging information.
8586 (tag_find_or_name): Don't insert tags in the symbol table.
8587 (yank_symbols): Don't merge labels.
8588 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8592 used in AT&T i386 syntax.
8593 (fixup_segment): Take segment as argument. On the i386, adjust PC
8594 relative addends by the segment vaddr.
8595 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
8596 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

8705 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
8707 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

8736 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8739 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8768 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8770 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8771 constant will not fit in an immediate field.
8772 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
8774 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

8807 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8809 * Support for i386-sysv.
8810 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8845 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8847 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
8848 * tc-z8k.c: lots of bug fixes
8850 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8852 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8853 #elif, since it is not supported by old compilers.
8854 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8855 couple of expressions in tc-m68k.c.
8857 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8859 * read.c (cons): If NO_RELOC is defined, use it.
8861 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8863 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8865 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8866 local labels to start with a .) and set REGISTER_PREFIX to %.
8867 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8869 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
8871 * messages.c: Comment changes.
8873 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
8875 * as.h: Test if __STDC__ is defined only, don't test its value.

8880 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8883 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8885 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8886 sections starting from zero, rather than making them consecutive.
8887 This makes subsequent reloc calculations easier, esp if the object
8888 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8889 allocate lcomm in .data rather than in .bss. It seems that some
8890 tools can't cope with a non-zero sized bss before linkage.
8892 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8894 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8895 throughout. That enum no longer means what we thought it meant.

8916 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8918 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8919 .word is < -32768 or > 32767. The -J flag causes the error to be
8920 ignored. This is to catch over-sized switches generated by gcc on
8921 systems which don't support the broken .word hack.
8922 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8923 write.c (fixup_segment): check for signed .word overflow if
8924 WARN_SIGNED_OVERFLOW_WORD.

8953 From Steve Chamberlain:
8954 Makefile.in: Handle m68*-*-coff*.
8955 read.c, read.h: add mult argument to s_space
8957 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8958 Motorola and MIT syntax; gas can now assemble either type of

9002 * config/tc-m68k.c (init_table): Now const. Always include 68851
9003 data, so that "bc" is available to 68040 cache instructions.
9004 Added "tt0", "tt1", and 68ec030 variants.
9005 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9006 (enum _register): Added TT0, TT1.
9007 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9008 line number correctly in "internal error" messages. Don't print

9034 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9035 has already been formatted (but may still contain %-characters).
9038 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9040 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9041 written with indirection on the last two operands, which can be
9042 either data or address registers. Added a new operand type 'r'
9043 which accepts either register type. Added '(' to notend stuff in
9044 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9390 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9391 local labels didn't work.
9392 * listing.c (list_symbol_table): don't core dump when there's no
9394 * write.c, write.h: call fix_new with the right number of args on
9396 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9399 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9401 * app.c: MRI compatibility - allow single quote to start a string.
9402 * as.c: fix typo recently introduced.
9403 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9404 * expr.c: Much rewriting, to accomodate MRI syntax for
9405 expressions. Also easier to read now.
9406 * listing.c: Put back defuns
9407 * read.c: modified to accept MRI syntax, put back listing pseudo
9408 ops so that an assembler built with NO_LISTING ignores list ops
9410 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9411 machine is a SPARC or a 29K.
9412 * config/obj-aout.c: added s_sect pseudo op
9413 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9414 fill in the timestamp.
9415 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9416 anymore, define all the relocs which the tc-<x> bit will use so we
9417 can translate from them to the coff types.
9418 * config/tc-a29k.c: reloc_type isn't ane enum any more
9419 * config/tc-m68k.c: Added NO_RELOC definition.
9421 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9423 * Makefile.in: put header files before C source for TAGS; remove
9424 references to non-existent syscalls.h.
9426 * read.c, write.c subsegs.c: back out the .bss changes.
9428 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9430 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9434 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9436 * symbols.c (local_label_name): symbols now start with ^A.
9438 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9439 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9440 generate these sections. .align: will use NOP_OPCODE or 0
9441 for padding. This is just for being nice to the
9444 * expr.c (operand): changed to generate local label "\001L0"
9445 starting with a ^A so that it is recognized as a local label.
9447 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9449 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9450 i/o opcodes - inb, inw, outb and outw. string manipulation with
9451 att syntax - scmp, slod, smov, ssca, ssto.
9453 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9454 to just after .file .
9456 In obj_crawl_symbol_chain() where it tries to put the external
9457 symbols apart, with the condition:
9458 (!S_IS_DEFINED(symbolP) &&
9459 !S_IS_DEBUG(symbolP) &&
9460 !SF_GET_STATICS(symbolP))
9461 it was moving too many symbols out. So I switch it back to the
9463 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9465 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9466 so that we don't use the F_RELFLG which make the linker complain
9467 that somebody has stripped the relocation info.
9469 Also, the AIX ld program require that the relocation table
9470 is sorted by r_vaddr like the standard ATT assembler does.
9472 [he also changed the sizeof(struct ...)'s into the coff
9473 style FOOSZ macros. I'm not sure this is right, but I can't
9474 remember why. xoxorich.]
9476 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9478 * Makefile.in, configure.in, doc: use the doc. Build it, install
9481 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9483 * read.c: white space and comments only.
9485 * configure.in: use the new atof-ns32.c for ns32k.
9487 * write.c: comment change only.
9489 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9490 aren't yet integrated.
9492 * tc-i860.[hc]: blew off the dust. Something must still be done
9493 about conflicting relocation types.
9495 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9498 * tc-i960.c, tc-sparc.c: white space and comments only.
9500 * tc-a29k.h: delete duplicate macro definition.
9502 * new file atof-ns32k.c copied from hack's last unreleased gas.
9504 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9506 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9509 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9510 ChangeLog's prior to this are sketchy at best. I have logs.
9511 They just aren't ChangeLogs.
9518 version-control: never
