988 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
990 * configure.in: Set bfd_gas for all sparc targets in one place,
991 instead of separately for each. Correctly handle user-supplied
992 "--enable-bfd-gas" option.
994 * gdbinit.in: Move "break abort" to end, in case gdb complains.
996 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
999 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
1000 processing if add_symbol is undefined or in expr_section.
1001 (resolve_symbol_value, case O_add): For symbol plus
1002 constant-valued symbol, convert to O_symbol and re-reduce.

1004 (indent_level): No longer static.
1005 (print_symbol_value_1): Don't print frag address if it matches
1006 zero_address_frag. Don't print "resolving" if already resolved.

1009 (print_expr_1): Fix whitespace before printing X_add_number.
1011 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1012 not symbol_new, for symbols holding expression values.
1013 * expr.h (make_expr_symbol): Move declaration here.
1014 * write.c (fix_new_exp): Handle O_add by creating an
1015 expression-valued symbol, and calling fix_new_exp recursively.
1016 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1017 undefined symbol and a constant, fold the constant into the fixup,
1018 and refer to the undefined symbol directly. Then process the
1019 fixup again from scratch.
1020 (write_object_file): Before calling adjust_reloc_syms, make a pass
1021 through the symbol list trying to resolve values.
1023 * write.c (print_fixup): New routine, for debugging.
1024 (write_relocs): Call bfd_install_relocation. Deleted various
1025 hacks for working around problems with bfd_perform_relocation.
1027 * Makefile.in (VERSION): Update to 2.4.90.

1035 not assembling PIC code, replace it with a j or jal.
1037 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1038 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

1046 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1048 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1049 here. Use them for deciding which PRINTF*LIKE macro definitions
1051 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1052 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1053 default definitions matching what we were doing before.
1054 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1055 always use the varargs form if not using stdarg. It's safe to
1056 always use vfprintf, because libiberty will provide it if the
1057 native system doesn't. Also, always make format be const.
1058 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

1074 deciding whether to record it.
1075 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1076 false (if defined) as well as checking for reg_section.
1077 (listing_listing): Iterate fetching lines while line number is too
1078 low, and we haven't run off the end of the input file.
1080 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1082 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1084 * ecoff.c (ecoff_generate_asm_lineno): check if

1091 * config/ho-*.h: Now-unused files deleted.
1093 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1094 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1095 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1096 zero. Don't call obj_frob_forward_symbol.
1097 * read.c (pseudo_set): Call copy_symbol_attributes, but only if

1099 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1101 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1103 (strchr): Don't declare.

1105 md_estimate_size_before_relax, md_ri_to_chars,
1106 md_create_short_jump, md_create_long_jump.
1107 (brtab_emit): Use data_section, not SEG_DATA.
1109 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1111 * config/vms-conf.h: new file, manually derived from conf.in.
1112 * config-gas.com: use it, and eliminate obsolete "host.h".

1122 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1123 from the csect of the enclosing block.
1125 * config/tc-mips.c (insns_since_cache_access): Remove.
1126 (append_insn): Remove setting of insns_since_cache_access, and
1127 special 4600 handling; it turns out not to be required.
1129 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1131 * config/tc-mips.c (md_shortopts): Remove E.
1132 (md_longopts): Add EB and EL.
1133 (md_parse_option): Handle -EB and -EL as separate options, rather
1134 than as a single -E option with an argument.

1143 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1145 * configure.in: Test for remove, not delete. Fix cross-assembler
1147 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1150 * read.c (pseudo_set, case O_symbol): If
1151 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1152 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1153 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1155 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1157 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1158 many others): new macros; values obtained from "DSTRECRDS.SDL".
1159 * config/obj-vms.h (various): use them.
1160 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1161 representation (only enum bitfields can avoid being bitstrings).
1162 (bitfield_suffix, setup_basic_type): new routines.
1163 (VMS_typedef_parse): use them. Now recognize bitfields of all
1164 integral types, not just type `int'. Caveat: the representation
1165 used for bitfields still does not work for objects placed in
1166 registers, and gcc's optimizer sometimes puts small structs there.
1168 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1170 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1171 bit from const_flag.
1172 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

1174 and declare the latter.
1175 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1177 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1178 (vms_check_for_special_label): new routine (tc_frob_label).
1179 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1180 and `gcc2_compiled.' labels; they won't reach here any more.
1181 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1182 double', use `vax_g_doubles' flag to select type of double.
1183 (VMS_write_object_file) [traceback setup]: don't pass symbols
1184 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1185 and TBT_Routine_End functions.

1189 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1190 S_GET_VALUE() to avoid many repeated function calls.
1191 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1192 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1193 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1194 be obsolete; gcc does it automatically for vms target. It's
1195 also misnamed, because it is for the "VAX C" run-time library,
1196 not the newer "DEC C" one which has much different startup code.]
1197 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1198 `S_GET_xxx(symbol) = new_value'.
1200 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1202 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,

1205 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1207 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1209 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1211 * expr.c (expr): Don't reduce the difference of two symbols in the
1212 same frag if the symbols are not in normal sections.
1214 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1215 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1216 (obj_attach_unwind_info): Do not define. Not needed anymore.
1217 * config/tc-hppa.c: Delete whitespace at EOL.
1218 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1219 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1220 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1221 fixups, store 32bits of unwind information in the fx_addnumber
1223 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1224 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1225 pointer to 32 bits of unwind info.
1226 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1227 pointer to the dummy symbol; set the addend field to fx_addnumber.
1228 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1229 rather than &bfd_XXX_section.
1231 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1233 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1234 value by one; discard adjustments previously being made. From
1237 VMS- and Vax-related changes from Pat Rankin:
1238 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1239 * vmsconf.sh: no longer have make-gas.com echo text about needing
1240 to modify the gcc-vms driver when intending to use with gcc 1.x.
1241 * as.c (parse_options): suppress 'v' from std_short_options and
1242 eliminate VMS-specific conditional initialization;
1243 [default case]: check for '-v' if md_parse_options doesn't recognize
1245 [default case, #if VMS]: check for filename argument when '-v' seen;
1247 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1248 for O_big literal operands (double floats and long long ints);
1249 [VMS, md_shortopts]: add second colon after 'v';
1250 (md_parse_options) [VMS, case 'v']: check for argument, so
1251 caller can handle `-v' w/o arg.

1395 (s_mips_globl): New static function; needed for Irix 5 support.
1396 * ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
1397 external symbol with no type, set the type to st_Proc rather than

2375 VMS debugger now recognizes `long long' variables correctly.
2376 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
2377 for gcc2's predefined types "long double" (same as double, as
2378 per gcc's current state), "long long int", "long long unsigned
2379 int", and final `otherwise' case (to avoid uninitialized type
2380 and size fields). [caveat: predefined types "complex int",
2381 "complex float", "complex double", and "complex long double" are
2384 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
2385 of 0, because the latter indicates success rather than failure

2750 directory, and specify PSECT attributes explicitly to linker.
2751 Also added missing label.

2841 don't spew remainder of input file in error message.
2842 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2843 message with reloc type and try to process remainder of file.
2845 * doc/Makefile.in (install-info-as, install-info-gasp): New
2846 targets, now explicitly checking $(srcdir) for info files.
2847 (install-info): Depend on both of them; do nothing more.

2855 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2856 flag rather than signedp field. Only permit extended range if
2857 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2858 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2860 * config/tc-ppc.c (ppc_size): New static variable.
2861 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2862 (md_begin): If an instruction has a size specific flag set, only
2863 add it if we are assembling that size.
2865 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2867 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2868 cross section PC relative relocs right for COFF and ELF.
2870 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

2883 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2884 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2885 and -many (all architectures).

2896 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2898 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2899 branch with an instruction that uses $at, in case the branch is
2901 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2902 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2903 to make it pcrel_offset.
2904 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2905 reloc->address; another gruesome hack to get gas reloc handling to

2910 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2913 (emit_insn): New function.
2914 (md_assemble): Call it.
2915 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2917 (lituse_pending): New variable. Set by anything that generates a
2918 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2919 tested by code that might want to emit a LITUSE reloc.
2920 (emit_unaligned_io): New function. Currently calls md_assemble,
2921 but it should eventually be converted to generate the insn itself
2922 and call emit_insn directly.
2923 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2924 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2925 emit_bis_r): Likewise.

2934 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2936 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2937 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2938 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

2953 (load_address): Handle EMBEDDED_PIC.
2954 (macro): Handle EMBEDDED_PIC in all PIC cases.
2955 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2956 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2957 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2958 works). Do not permit -G with SVR4_PIC.
2959 (s_abicalls): Warn if -G was used, and force -G 0.
2960 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2961 anything but a.out, not just for ELF. For ECOFF, don't generate a
2962 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2964 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2966 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2968 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2969 parameters to avoid losing when compiling with HP CC.
2970 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2972 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2974 * Makefile.in (config-stamp): If `defs' is defined, emit a
2975 preprocessor directive to create a macro named by this value into
2976 config.new; don't explicitly go for BFD_ASSEMBLER.
2977 * configure.in: Define `defs', not `BFDDEF'. Set it to
2978 MANY_SEGMENTS for any obj-coffbfd target.
2979 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2980 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2982 (LOCAL_LOADLIBES): Deleted.
2983 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2984 * config/m88kcoff.mt (TDEFINES): Ditto.

2988 * config/sparc.mt: Deleted.
2989 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

3010 bfd_set_symtab is called.
3011 (dump_section_relocs): Note whether a symbol is a section symbol
3013 (adjust_reloc_syms): For now, always supply an absolute symbol for
3014 fixups without symbols but not yet `done'. Use section_symbol to
3015 get the symbol, instead of going directly for abs_symbol.
3016 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3017 reloc is not a section symbol and is not in the symbol table.
3018 (set_symtab): New function, broken out from write_object_file.
3019 Counts symbol table instead of relying on an earlier count.
3020 (write_object_file): Call set_symtab, but do it after potentially
3021 invoking the *_frob_file macros. Don't bother counting symbols.
3022 Call symbol_remove, instead of expanding it in place. Moved the
3023 conditionalized `object_file_size' declaration down to
3024 conditionalized block where it's used. When using the absolute
3025 symbol for a fixup without a symbol, set sy_used_in_reloc.
3026 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3027 the correct symbol for the absolute section.
3029 * subsegs.c (section_symbol): Use symbol_new instead of
3030 symbol_make, since we may want it to go into the symbol table.
3031 Make the new symbol have internal linkage. If
3032 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3033 symbol with the newly created GAS symbol.
3034 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3035 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

3040 (in_signed_range): New function.
3042 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3043 (sparc_ip, label "immediate"): Reject constants for pcrel
3044 instructions only if the relocation type indicates a "call"
3045 instruction and the offset is within range of a "jmpl %g0". If
3046 it's not in range, use the absolute section symbol plus an offset.
3047 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3049 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3051 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3054 * configure.in: Eliminated all targets using obj-coff but not
3055 defining BFD_ASSEMBLER; I think all such targets that are
3056 supported will be matched by real CPU-OS combinations earlier in
3058 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3059 some comments about the dpx2 configuration, but left it disabled,
3060 since it couldn't be reached before.
3061 (target a29k-amd-ebmonold): Deleted.
3063 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3071 the 'j' operand if there are no further alternatives for this
3074 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3075 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3076 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3078 * config/tc-mips.c (mips_align): Take new argument, label, and use
3079 it instead of global insn_label.
3080 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3081 call to mips_emit_delay and pass it to mips_align.
3083 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3085 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3087 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3088 argument to a .callinfo directive. Don't loop forever on errors.
3090 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3091 use pre-defined registers as arguments.

3096 S_IS_EXTERNAL when deciding whether to discard a symbol.
3098 * config-gas.com: Scan Makefile.in, not version.c, for current
3099 version number. Delete all versions of temp files when finished
3100 with them. Create config.h.
3102 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
3103 values to reduce number of lookups with S_GET_VALUE. Skip debug
3104 symbols to avoid "a really nasty bug". (From Holger Teutsch,
3105 holger@botbso.rhein-main.de.)
3106 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
3107 field. (Also from Holger Teutsch.) Watch for a would-be register
3108 mask that spans frags.
3110 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
3111 this_base, not line_base. (Patch from Andreas Arens,
3112 ari@obelix.av.rwth-aachen.de.)
3114 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
3115 look local if they're exported or undefined. Used to be done for
3118 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
3119 Get it from the looked-up symbol, instead of using the string from
3120 the input stream, which is no longer null-terminated.
3121 (LEX_PCT): New macro, defaults to 0.
3122 (lex_type): Use it for `%'.
3124 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

3174 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
3175 0xffff for 'j' to be compatible with MIPS assembler. These

5247 * configure.in: Set bfd_gas for all sparc targets. Added facility
5248 for keeping or rejecting configurations still under development;
5249 default is to assume production environment, and reject configs
5250 still being worked on. Mark Elf configurations (except sparc and
5251 i386) as developmental. Deleted cases matching some generic names
5252 in favor of more specific names. (E.g., when we get Alpha

5278 into a few places. Make all functions and variables which
5279 are only used within tc-hppa.c static. PARAMize all functions.
5280 Add comments to functions. Delete unused functions, variables,
5281 #defines, etc. Delete unused members within structures. Delete
5282 ldil;ble hacks -- it is believed they were installed to work
5283 around old gas bugs. Avoid using mixed case for local
5284 functions, variables, and structures. Fix formatting problems
5285 not found by GNU-indent. Add FIXME notices for things which
5286 should be worked on the near future. Delete lots of old
5287 useless (1.36 PA-SOM) code.

5306 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
5307 of elf32_symbol_type.
5308 (pa_export_args): Likewise.

5316 a multiple of the section alignment rather than always a
5319 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5320 bits are zero (eg they specify no relocations), then do not even
5321 bother adding their entries to thesymextn section.

5366 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5368 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5369 ELF, since the ELF object format does not have these type of
5370 relocations. Change the abort into as as_bad and return
5371 BFD_RELOC_NONE to silence compiler warnings.
5372 (md_assemble): Keep track of the instruction size. Allow white
5373 space between the $ and the constant for compatibility with older

7818 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7825 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

7858 dropping a space immediately following an identifier.

7860 lines; I don't think that can be done portably.
7861 * config/tc-mips.c (macro): Use $AT if target register is zero in

7986 * make-gas.com: Find obstack.obj if it's not in the current
7988 * read.c (s_ignore): Don't declare is_end_of_line. It's
7989 redundant, and triggers a VMS gcc compiler bug.

8046 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8047 constants are accepted, but symbolic values are not. GCC will not
8048 generate the latter currently.
8050 * frags.c (frag_init): New function.
8051 (zero_address_frag, bss_address_frag): Now initialized at run
8053 * as.c (main): Call frag_init.

8324 (operand): Treat zero byte as end-of-operand.
8326 * configure.in (per-target): Look for with_bfd_assembler option.
8327 For now, only accept "no", until the merge is done.
8329 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):

8336 * expr.c: Add "const" modifier to hex_value.
8337 * symbols.c: Finish conversion to S_* macros in the VMS only

8339 md_[long,short]_jump_size. Remove declaration of const_flag
8340 (which will be declared in obj-vms.h).
8341 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8342 Fix arguments to VMS_write_object_file.
8343 * config-gas.com: New file. Script for VMS systems to set up the

8405 if these are used or defined, if BFD_ASSEMBLER.
8406 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8407 subseg_new split into two functions.
8408 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8410 * as.h (volatile): Don't define if already defined.

8413 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8414 declare with format attribute for -Wformat checking.
8416 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8418 * app.c, config/tc-*.c: Don't include read.h, since it is already
8421 * These are based on patches from Minh Tran-le
8422 <mtranle@paris.intellicorp.com>.
8423 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8424 obj_format coffbfd and gas_target i386coff for target.
8425 (i[34]86-*-isc*): New host (uses sysv).
8426 * config/i386aix.mt: Removed (no longer used).
8427 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8429 (LDFLAGS): Added, defined as -shlib.
8430 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8431 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8432 (DOT_LABEL_PREFIX): Define.
8433 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8434 name rather than L0\001.
8435 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8437 * symbols.c, symbols.h (local_bss_counter): Removed.
8438 * write.c (write_object_file): bss no longer uses
8439 local_bss_counter. Pass correct data and bss size to
8440 VMS_write_object_file.
8441 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
8442 argument, rather than using local_bss_counter.

8444 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
8445 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
8446 (size_section): Restored sanity check.
8447 (do_relocs_for): Base section address on s_paddr rather than
8448 computing it. Adjust a29k R_IHIHALF special case to account for
8449 section paddr (used to require paddr to be zero). If there are no
8450 reclos, set s_relptr to 0. Set relocation size in object_headers.
8451 (fill_section): Always set s_vaddr here, removing
8452 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8453 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8454 Set STYP_INFO for .comment.
8455 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
8456 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

8458 H_{SET,GET}_* macros.
8459 (do_linenos_for): Set lineno size in object_headers.
8460 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8461 set s_vaddr here. If string_byte_count remains 4, set it back to
8462 0, and only write strings out if there are some. Call
8463 fill_section before do_relocs_for and do_linenos_for.
8464 (obj_coff_section): Handle optional quoted second argument giving
8465 section characteristics.
8466 (obj_coff_bss): Added to handle .bss.
8467 (obj_coff_ident): Added to handle .ident (puts string in .comment
8469 (obj_coff_lcomm): Put common symbols in .bss, not .data.
8470 (fixup_mdeps): Change to segment. Call frag_wane after
8472 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8473 adjustment (already happened only for common symbols, but this is
8475 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8476 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8486 * app.c (app_push): Use memcpy, not bcopy.
8487 (do_scrub_next_char): For \", return " not '.
8488 (symbol_chars): Now const.
8490 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8491 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8493 * config/obj-coff.h: Don't use #elif.
8495 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8496 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
8498 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

8522 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8523 using ZERO_BASED_SEGMENTS.
8524 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8525 never set segment address for SEG_E2 (.bss) and don't write out
8526 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8527 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8528 definitions, and don't merge tags with non-tags. Check for .bf
8529 rather than just checking whether the second character is b and
8530 the third character is f.
8531 (obj_coff_val): gcc can generate values which we don't handle
8532 correctly; discard information for now, since it only affects the
8533 debugging information.
8534 (tag_find_or_name): Don't insert tags in the symbol table.
8535 (yank_symbols): Don't merge labels.
8536 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8539 (obj_coff_section): Accept and ignore a trailing quoted string, as
8540 used in AT&T i386 syntax.
8541 (fixup_segment): Take segment as argument. On the i386, adjust PC
8542 relative addends by the segment vaddr.
8543 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
8544 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

8681 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
8682 could be doing emulation.
8684 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8687 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8716 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8718 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8719 constant will not fit in an immediate field.
8720 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
8722 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

8755 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8757 * Support for i386-sysv.
8758 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

8782 * tc-m68k.c (get_num): make it work for all segments, not just the
8785 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8787 * configure.in: recognize i386-*-bsd emulation.

8796 * tc-z8k.c: lots of bug fixes
8798 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8800 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8801 #elif, since it is not supported by old compilers.
8802 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8803 couple of expressions in tc-m68k.c.
8805 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8807 * read.c (cons): If NO_RELOC is defined, use it.
8809 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8811 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8813 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8814 local labels to start with a .) and set REGISTER_PREFIX to %.
8815 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8817 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
8819 * messages.c: Comment changes.
8821 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

8824 * messages.c: If __STDC__ is not defined, define NO_STDARG.
8826 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
8828 * listing.c (debugging_pseudo): Add stabs and stabn as things to
8831 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8833 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8834 sections starting from zero, rather than making them consecutive.
8835 This makes subsequent reloc calculations easier, esp if the object
8836 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8837 allocate lcomm in .data rather than in .bss. It seems that some
8838 tools can't cope with a non-zero sized bss before linkage.
8840 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8842 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8843 throughout. That enum no longer means what we thought it meant.
8845 * tc-m68k.c (md_assemble, md_parse_option): Handle new
8846 "-mno-688[58]1" options.
8848 * tc-m68k.c: Added CPU32 support.
8850 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8852 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
8854 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8856 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
8857 Change LIBDEPS dependence to LIBS.
8859 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
8861 * Makefile.in (install): if $(tooldir) exists, install as in
8864 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8866 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8867 .word is < -32768 or > 32767. The -J flag causes the error to be
8868 ignored. This is to catch over-sized switches generated by gcc on
8869 systems which don't support the broken .word hack.
8870 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8871 write.c (fixup_segment): check for signed .word overflow if
8872 WARN_SIGNED_OVERFLOW_WORD.
8874 * write.c (fixup_segment): fixed missing parens in expression
8875 checking for byte or word overflow.
8877 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
8878 obj-coffbfd.c (fixup_segment): check for signed .word overflow if

8886 Support for i386 coff
8887 * obj-coffbfd.h : added stuff
8888 * tc-i386.c (tc_coff_fix2rtype): new function
8889 * tc-i386.h : new coff defines
8891 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8893 * input-scrub.c (input_scrub_push): call input_file_begin, not

8988 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8989 written with indirection on the last two operands, which can be
8990 either data or address registers. Added a new operand type 'r'
8991 which accepts either register type. Added '(' to notend stuff in
8992 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9331 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9333 * expr.c: If an expression is single comma, then return with
9334 SEG_ABSENT rather than an error - since the sparc front end does
9335 really strange things with things like fbge,a
9337 * as.h: include bfd.h if using many sections
9338 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

9347 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9349 * app.c: MRI compatibility - allow single quote to start a string.

9351 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9352 * expr.c: Much rewriting, to accomodate MRI syntax for
9353 expressions. Also easier to read now.
9354 * listing.c: Put back defuns
9355 * read.c: modified to accept MRI syntax, put back listing pseudo
9356 ops so that an assembler built with NO_LISTING ignores list ops
9358 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9359 machine is a SPARC or a 29K.
9360 * config/obj-aout.c: added s_sect pseudo op
9361 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9362 fill in the timestamp.
9363 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9364 anymore, define all the relocs which the tc-<x> bit will use so we
9365 can translate from them to the coff types.
9366 * config/tc-a29k.c: reloc_type isn't ane enum any more
9367 * config/tc-m68k.c: Added NO_RELOC definition.

9382 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9384 * symbols.c (local_label_name): symbols now start with ^A.
9386 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9387 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9388 generate these sections. .align: will use NOP_OPCODE or 0
9389 for padding. This is just for being nice to the
9392 * expr.c (operand): changed to generate local label "\001L0"
9393 starting with a ^A so that it is recognized as a local label.
9395 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9397 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9398 i/o opcodes - inb, inw, outb and outw. string manipulation with
9399 att syntax - scmp, slod, smov, ssca, ssto.
9401 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9402 to just after .file .
9404 In obj_crawl_symbol_chain() where it tries to put the external
9405 symbols apart, with the condition:
9406 (!S_IS_DEFINED(symbolP) &&
9407 !S_IS_DEBUG(symbolP) &&
9408 !SF_GET_STATICS(symbolP))
9409 it was moving too many symbols out. So I switch it back to the
9411 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9413 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9414 so that we don't use the F_RELFLG which make the linker complain
9415 that somebody has stripped the relocation info.
9417 Also, the AIX ld program require that the relocation table
9418 is sorted by r_vaddr like the standard ATT assembler does.
9420 [he also changed the sizeof(struct ...)'s into the coff
9421 style FOOSZ macros. I'm not sure this is right, but I can't
9422 remember why. xoxorich.]

9426 * Makefile.in, configure.in, doc: use the doc. Build it, install
9429 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9431 * read.c: white space and comments only.
9433 * configure.in: use the new atof-ns32.c for ns32k.
9435 * write.c: comment change only.
9437 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9438 aren't yet integrated.
9440 * tc-i860.[hc]: blew off the dust. Something must still be done
9441 about conflicting relocation types.
9443 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9446 * tc-i960.c, tc-sparc.c: white space and comments only.
9448 * tc-a29k.h: delete duplicate macro definition.
9450 * new file atof-ns32k.c copied from hack's last unreleased gas.
9452 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9454 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9457 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9458 ChangeLog's prior to this are sketchy at best. I have logs.
9459 They just aren't ChangeLogs.
9466 version-control: never
