1015 referring to PLT entries.
1016 * write.c (fix_new_internal): Initialize fx_plt to zero.
1017 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.

1046 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1048 * configure.in: Set bfd_gas for all sparc targets in one place,
1049 instead of separately for each. Correctly handle user-supplied
1050 "--enable-bfd-gas" option.
1052 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1054 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

1062 (indent_level): No longer static.
1063 (print_symbol_value_1): Don't print frag address if it matches

1067 (print_expr_1): Fix whitespace before printing X_add_number.
1069 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1070 not symbol_new, for symbols holding expression values.
1071 * expr.h (make_expr_symbol): Move declaration here.
1072 * write.c (fix_new_exp): Handle O_add by creating an
1073 expression-valued symbol, and calling fix_new_exp recursively.
1074 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1075 undefined symbol and a constant, fold the constant into the fixup,
1076 and refer to the undefined symbol directly. Then process the
1077 fixup again from scratch.
1078 (write_object_file): Before calling adjust_reloc_syms, make a pass
1079 through the symbol list trying to resolve values.
1081 * write.c (print_fixup): New routine, for debugging.
1082 (write_relocs): Call bfd_install_relocation. Deleted various
1083 hacks for working around problems with bfd_perform_relocation.
1085 * Makefile.in (VERSION): Update to 2.4.90.

1100 * write.c (write_relocs): Add file name and line number to
1101 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1102 RELOC_EXPANSION_POSSIBLE.
1104 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1106 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1107 here. Use them for deciding which PRINTF*LIKE macro definitions

1110 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1111 default definitions matching what we were doing before.
1112 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1113 always use the varargs form if not using stdarg. It's safe to
1114 always use vfprintf, because libiberty will provide it if the
1115 native system doesn't. Also, always make format be const.
1116 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

1132 deciding whether to record it.
1133 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1134 false (if defined) as well as checking for reg_section.
1135 (listing_listing): Iterate fetching lines while line number is too
1136 low, and we haven't run off the end of the input file.
1138 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1140 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1142 * ecoff.c (ecoff_generate_asm_lineno): check if

1149 * config/ho-*.h: Now-unused files deleted.
1151 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1152 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1153 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1154 zero. Don't call obj_frob_forward_symbol.

1163 md_estimate_size_before_relax, md_ri_to_chars,
1164 md_create_short_jump, md_create_long_jump.
1165 (brtab_emit): Use data_section, not SEG_DATA.
1167 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1169 * config/vms-conf.h: new file, manually derived from conf.in.
1170 * config-gas.com: use it, and eliminate obsolete "host.h".

1180 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1181 from the csect of the enclosing block.
1183 * config/tc-mips.c (insns_since_cache_access): Remove.
1184 (append_insn): Remove setting of insns_since_cache_access, and
1185 special 4600 handling; it turns out not to be required.
1187 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1189 * config/tc-mips.c (md_shortopts): Remove E.
1190 (md_longopts): Add EB and EL.
1191 (md_parse_option): Handle -EB and -EL as separate options, rather

1201 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1203 * configure.in: Test for remove, not delete. Fix cross-assembler
1205 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to

1209 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1210 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1211 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1213 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1215 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1216 many others): new macros; values obtained from "DSTRECRDS.SDL".
1217 * config/obj-vms.h (various): use them.
1218 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1219 representation (only enum bitfields can avoid being bitstrings).
1220 (bitfield_suffix, setup_basic_type): new routines.
1221 (VMS_typedef_parse): use them. Now recognize bitfields of all
1222 integral types, not just type `int'. Caveat: the representation
1223 used for bitfields still does not work for objects placed in
1224 registers, and gcc's optimizer sometimes puts small structs there.
1226 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1228 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1229 bit from const_flag.
1230 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

1232 and declare the latter.
1233 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1235 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1236 (vms_check_for_special_label): new routine (tc_frob_label).
1237 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1238 and `gcc2_compiled.' labels; they won't reach here any more.
1239 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1240 double', use `vax_g_doubles' flag to select type of double.
1241 (VMS_write_object_file) [traceback setup]: don't pass symbols
1242 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1243 and TBT_Routine_End functions.

1247 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1248 S_GET_VALUE() to avoid many repeated function calls.
1249 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1250 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1251 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1252 be obsolete; gcc does it automatically for vms target. It's
1253 also misnamed, because it is for the "VAX C" run-time library,
1254 not the newer "DEC C" one which has much different startup code.]
1255 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1256 `S_GET_xxx(symbol) = new_value'.
1258 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1260 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1261 not &bfd_abs_section.
1263 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1265 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1267 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1269 * expr.c (expr): Don't reduce the difference of two symbols in the
1270 same frag if the symbols are not in normal sections.
1272 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1273 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1274 (obj_attach_unwind_info): Do not define. Not needed anymore.
1275 * config/tc-hppa.c: Delete whitespace at EOL.
1276 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1277 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1278 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1279 fixups, store 32bits of unwind information in the fx_addnumber
1281 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1282 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1283 pointer to 32 bits of unwind info.
1284 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1285 pointer to the dummy symbol; set the addend field to fx_addnumber.
1286 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1287 rather than &bfd_XXX_section.
1289 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1291 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1292 value by one; discard adjustments previously being made. From
1295 VMS- and Vax-related changes from Pat Rankin:
1296 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1297 * vmsconf.sh: no longer have make-gas.com echo text about needing
1298 to modify the gcc-vms driver when intending to use with gcc 1.x.
1299 * as.c (parse_options): suppress 'v' from std_short_options and
1300 eliminate VMS-specific conditional initialization;
1301 [default case]: check for '-v' if md_parse_options doesn't recognize
1303 [default case, #if VMS]: check for filename argument when '-v' seen;
1305 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1306 for O_big literal operands (double floats and long long ints);
1307 [VMS, md_shortopts]: add second colon after 'v';
1308 (md_parse_options) [VMS, case 'v']: check for argument, so
1309 caller can handle `-v' w/o arg.

1354 Rewrite handling of program_transform_name.
1356 * configure.in: Test for functions unlink and delete.

1367 to ensure that older versions of autoconf aren't used.
1368 * Makefile.in: Added @configure_input@ line.
1369 (configure): Deleted rule.
1371 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1373 * config/obj-coff.c (fixup_segment): After handling the difference
1374 of two symbols from the same segment, set fx_subsy to NULL, to

2360 (control_regs): New pointer.
2361 (m68k_ip): Use control_regs instead of testing CPU every time.

2369 * config/obj-coff.c (fixup_segment) [!BFD_ASSEMBLER]
2370 [DIFF_EXPR_OK]: Do conversion to pc-relative for difference, even
2371 if pcrel is already set.
2373 * read.c (potable): Add this_gcc_requires_the_gnu_assembler in all
2374 lower-case, in case we're ignoring case of opcodes in the input

2434 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
2435 for gcc2's predefined types "long double" (same as double, as
2436 per gcc's current state), "long long int", "long long unsigned

2439 "complex float", "complex double", and "complex long double" are
2442 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
2443 of 0, because the latter indicates success rather than failure

2449 allocating new symbol entry and linking it to VMS_Symbol_type_list.
2451 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
2453 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret

2802 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2804 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2806 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2807 source files from other directories into objects in the current
2808 directory, and specify PSECT attributes explicitly to linker.
2809 Also added missing label.
2810 * Makefile.in (stamp-mk.com): Reference new variable

2830 (macro): Likewise. For M_LA_AB permit a difference expression
2831 when generating embedded PIC code between an arbitrary symbol and
2832 a symbol in the .text section.
2833 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2834 BFD_RELOC_PCREL_LO16 to be emitted.

2874 (hppa_tc_symbol): Likewise.
2876 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2877 elf_tc_make_sections stuff. It was there to support PA braindamage
2878 which has been fixed, and in the case of elf_tc_make_sections is
2879 redundant with elf_tc_final_processing.

2899 don't spew remainder of input file in error message.
2900 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2901 message with reloc type and try to process remainder of file.

2913 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2914 flag rather than signedp field. Only permit extended range if
2915 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2916 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2918 * config/tc-ppc.c (ppc_size): New static variable.
2919 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2920 (md_begin): If an instruction has a size specific flag set, only
2921 add it if we are assembling that size.

2925 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2926 cross section PC relative relocs right for COFF and ELF.
2928 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2930 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

2941 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2942 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2943 and -many (all architectures).

2953 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2954 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2956 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2957 branch with an instruction that uses $at, in case the branch is
2959 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2960 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2961 to make it pcrel_offset.
2962 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2963 reloc->address; another gruesome hack to get gas reloc handling to
2966 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2968 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2971 (emit_insn): New function.
2972 (md_assemble): Call it.
2973 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2975 (lituse_pending): New variable. Set by anything that generates a
2976 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2977 tested by code that might want to emit a LITUSE reloc.
2978 (emit_unaligned_io): New function. Currently calls md_assemble,
2979 but it should eventually be converted to generate the insn itself
2980 and call emit_insn directly.
2981 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2982 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2983 emit_bis_r): Likewise.
2984 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2985 (alpha_ip, label get_macro): Don't emit the final instruction if
2987 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2988 unaligned memory access macros.
2989 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2990 the value can't be resolved.
2992 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2994 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2995 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2996 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

3008 * config/tc-mips.c (enum mips_pic_level): New enum.
3009 (mips_pic): Change from int to enum mips_pic_level. Change all
3010 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3011 (load_address): Handle EMBEDDED_PIC.
3012 (macro): Handle EMBEDDED_PIC in all PIC cases.
3013 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3014 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3015 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3016 works). Do not permit -G with SVR4_PIC.
3017 (s_abicalls): Warn if -G was used, and force -G 0.
3018 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3019 anything but a.out, not just for ELF. For ECOFF, don't generate a
3020 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3022 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3024 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3026 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3027 parameters to avoid losing when compiling with HP CC.
3028 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3030 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3032 * Makefile.in (config-stamp): If `defs' is defined, emit a
3033 preprocessor directive to create a macro named by this value into
3034 config.new; don't explicitly go for BFD_ASSEMBLER.
3035 * configure.in: Define `defs', not `BFDDEF'. Set it to
3036 MANY_SEGMENTS for any obj-coffbfd target.
3037 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3038 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3040 (LOCAL_LOADLIBES): Deleted.
3041 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3042 * config/m88kcoff.mt (TDEFINES): Ditto.
3043 * config/ebmon29k.mt: Deleted.

3068 bfd_set_symtab is called.
3069 (dump_section_relocs): Note whether a symbol is a section symbol
3071 (adjust_reloc_syms): For now, always supply an absolute symbol for
3072 fixups without symbols but not yet `done'. Use section_symbol to
3073 get the symbol, instead of going directly for abs_symbol.
3074 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3075 reloc is not a section symbol and is not in the symbol table.
3076 (set_symtab): New function, broken out from write_object_file.
3077 Counts symbol table instead of relying on an earlier count.
3078 (write_object_file): Call set_symtab, but do it after potentially
3079 invoking the *_frob_file macros. Don't bother counting symbols.
3080 Call symbol_remove, instead of expanding it in place. Moved the
3081 conditionalized `object_file_size' declaration down to
3082 conditionalized block where it's used. When using the absolute
3083 symbol for a fixup without a symbol, set sy_used_in_reloc.
3084 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3085 the correct symbol for the absolute section.
3087 * subsegs.c (section_symbol): Use symbol_new instead of
3088 symbol_make, since we may want it to go into the symbol table.
3089 Make the new symbol have internal linkage. If
3090 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3091 symbol with the newly created GAS symbol.
3092 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3093 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

3100 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3101 (sparc_ip, label "immediate"): Reject constants for pcrel
3102 instructions only if the relocation type indicates a "call"
3103 instruction and the offset is within range of a "jmpl %g0". If
3104 it's not in range, use the absolute section symbol plus an offset.
3105 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3107 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3109 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3112 * configure.in: Eliminated all targets using obj-coff but not
3113 defining BFD_ASSEMBLER; I think all such targets that are
3114 supported will be matched by real CPU-OS combinations earlier in
3116 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3117 some comments about the dpx2 configuration, but left it disabled,
3118 since it couldn't be reached before.
3119 (target a29k-amd-ebmonold): Deleted.
3121 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3129 the 'j' operand if there are no further alternatives for this
3132 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3133 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3134 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3136 * config/tc-mips.c (mips_align): Take new argument, label, and use
3137 it instead of global insn_label.
3138 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3139 call to mips_emit_delay and pass it to mips_align.
3141 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3143 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3145 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3146 argument to a .callinfo directive. Don't loop forever on errors.
3148 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3149 use pre-defined registers as arguments.

3154 S_IS_EXTERNAL when deciding whether to discard a symbol.
3156 * config-gas.com: Scan Makefile.in, not version.c, for current
3157 version number. Delete all versions of temp files when finished
3158 with them. Create config.h.
3160 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
3161 values to reduce number of lookups with S_GET_VALUE. Skip debug
3162 symbols to avoid "a really nasty bug". (From Holger Teutsch,
3163 holger@botbso.rhein-main.de.)
3164 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
3165 field. (Also from Holger Teutsch.) Watch for a would-be register
3166 mask that spans frags.
3168 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
3169 this_base, not line_base. (Patch from Andreas Arens,

3172 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
3173 look local if they're exported or undefined. Used to be done for
3176 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
3177 Get it from the looked-up symbol, instead of using the string from
3178 the input stream, which is no longer null-terminated.
3179 (LEX_PCT): New macro, defaults to 0.
3180 (lex_type): Use it for `%'.
3182 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

3232 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
3233 0xffff for 'j' to be compatible with MIPS assembler. These
3234 numbers are actually treated as negative.

3245 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this
3246 work. It still doesn't. It now fails to compile, instead of
3247 silently compiling to do nothing.
3248 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
3250 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

4817 Delete dead code. Simplify.
4818 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
4819 applied are in range. Use bfd_put_32 rather than inserting each

4935 an example of marker relocations.
4936 * write.c (write_relocs): Instead of assuming size of a relocation
4937 is 4 bytes, pick up the size from relocation itself.

5189 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
5190 the table, require that the one without bit 0x1000000 set come
5191 first. Require further that it be case 'b' or 'P'. The a29k
5192 opcode table already meets these constraints.
5193 (machine_ip): When handling case 'i' or 'A', make sure that the
5194 appropriate opcode really exists by looking at the next entry in

5249 * write.c (write_relocs): For relocs that are pc_relative and
5250 pcrel_offset and not partial_inplace, adjust reloc->addend to

5301 OPTIONAL_REGISTER_PREFIX if either is already defined.
5303 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5305 * configure.in: Set bfd_gas for all sparc targets. Added facility
5306 for keeping or rejecting configurations still under development;
5307 default is to assume production environment, and reject configs
5308 still being worked on. Mark Elf configurations (except sparc and
5309 i386) as developmental. Deleted cases matching some generic names
5310 in favor of more specific names. (E.g., when we get Alpha

5328 for functions only used within tc-hppa.c, likewise for structures,
5329 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5330 conditional code in a few small places.
5332 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5333 structures, global variables, forward declarations together.

5335 conditional code -- try to group conditional code together
5336 into a few places. Make all functions and variables which
5337 are only used within tc-hppa.c static. PARAMize all functions.
5338 Add comments to functions. Delete unused functions, variables,
5339 #defines, etc. Delete unused members within structures. Delete
5340 ldil;ble hacks -- it is believed they were installed to work
5341 around old gas bugs. Avoid using mixed case for local
5342 functions, variables, and structures. Fix formatting problems
5343 not found by GNU-indent. Add FIXME notices for things which
5344 should be worked on the near future. Delete lots of old
5345 useless (1.36 PA-SOM) code.

5374 a multiple of the section alignment rather than always a
5377 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5378 bits are zero (eg they specify no relocations), then do not even
5379 bother adding their entries to thesymextn section.

5423 of text, data and bss sections to 4.
5424 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5426 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5427 ELF, since the ELF object format does not have these type of
5428 relocations. Change the abort into as as_bad and return
5429 BFD_RELOC_NONE to silence compiler warnings.
5430 (md_assemble): Keep track of the instruction size. Allow white
5431 space between the $ and the constant for compatibility with older
5432 gases and other assemblers.

6507 * Extensive changes to permit symbols to contain any expression
6508 type and to delay the computation of the expression until the
6509 value is actually needed. This permits setting symbols to values
6510 calculated based on object code size. Expressions were changed to
6511 no longer be in a section, to stop the overloading of segment and
6512 expression type that previously occurred.

6600 (previous_section, previous_subsection): New vars.
6601 (obj_elf_section): Save current place in case DWARF code wants us
6602 to pop back to it. Handle unquoted section name as well as quoted
6603 section name. Don't crash on invalid strings.
6604 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

6716 sy_resolved and sy_resolving single bit fields.
6717 * symbols.c (symbol_new): Don't initialize sy_forward field.

7865 avoid some redefinition complaints on some systems.

7876 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

7883 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7885 * Makefile.in: add dvi target; as-$(config).texinfo might live in
7886 srcdir, might be in objdir.

7916 dropping a space immediately following an identifier.

7918 lines; I don't think that can be done portably.
7919 * config/tc-mips.c (macro): Use $AT if target register is zero in
7920 load instruction, which it can be for a floating point load.

8413 * obj-vms.c (final_forward_reference): New function, used to help
8414 resolve the data types of as many struct elements as possible
8415 when some part of the struct is not fully defined by the compiler.
8416 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
8418 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8419 as symbols as well in the object file. Look for external functions
8420 that start with "__vt.", and turn them into variables, since the
8421 g++ compiler is incapable of doing this.
8422 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8424 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8425 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8426 have the name of the source file yet.

8429 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8431 * read.c (s_data): Always use "data_section", since it'll map to
8432 SEG_DATA or SEG_E1 if needed.
8433 (s_lcomm): Likewise with bss_section.
8434 (s_fill): Use memset, not bzero.
8436 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8452 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
8453 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

8457 (section_alignment): Declare only if not BFD_ASSEMBLER.
8458 (big_section, reg_section, pass1_section, diff_section,
8459 absent_section, text_section, data_section, bss_section): If
8460 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8461 mapping to segT enum values.
8462 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8463 if these are used or defined, if BFD_ASSEMBLER.
8464 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8465 subseg_new split into two functions.
8466 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8468 * as.h (volatile): Don't define if already defined.
8469 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8471 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8472 declare with format attribute for -Wformat checking.
8474 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8476 * app.c, config/tc-*.c: Don't include read.h, since it is already
8479 * These are based on patches from Minh Tran-le
8480 <mtranle@paris.intellicorp.com>.
8481 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8482 obj_format coffbfd and gas_target i386coff for target.
8483 (i[34]86-*-isc*): New host (uses sysv).
8484 * config/i386aix.mt: Removed (no longer used).
8485 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8487 (LDFLAGS): Added, defined as -shlib.
8488 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8489 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8490 (DOT_LABEL_PREFIX): Define.
8491 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8492 name rather than L0\001.
8493 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8495 * symbols.c, symbols.h (local_bss_counter): Removed.

8504 (size_section): Restored sanity check.
8505 (do_relocs_for): Base section address on s_paddr rather than
8506 computing it. Adjust a29k R_IHIHALF special case to account for
8507 section paddr (used to require paddr to be zero). If there are no
8508 reclos, set s_relptr to 0. Set relocation size in object_headers.
8509 (fill_section): Always set s_vaddr here, removing
8510 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8511 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8512 Set STYP_INFO for .comment.

8516 H_{SET,GET}_* macros.
8517 (do_linenos_for): Set lineno size in object_headers.
8518 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8519 set s_vaddr here. If string_byte_count remains 4, set it back to
8520 0, and only write strings out if there are some. Call
8521 fill_section before do_relocs_for and do_linenos_for.
8522 (obj_coff_section): Handle optional quoted second argument giving
8523 section characteristics.
8524 (obj_coff_bss): Added to handle .bss.
8525 (obj_coff_ident): Added to handle .ident (puts string in .comment

8531 adjustment (already happened only for common symbols, but this is
8533 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

8545 (do_scrub_next_char): For \", return " not '.
8546 (symbol_chars): Now const.
8548 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8549 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8551 * config/obj-coff.h: Don't use #elif.
8553 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8554 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8581 using ZERO_BASED_SEGMENTS.
8582 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8583 never set segment address for SEG_E2 (.bss) and don't write out
8584 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8585 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8586 definitions, and don't merge tags with non-tags. Check for .bf
8587 rather than just checking whether the second character is b and
8588 the third character is f.
8589 (obj_coff_val): gcc can generate values which we don't handle
8590 correctly; discard information for now, since it only affects the
8591 debugging information.

8593 (yank_symbols): Don't merge labels.
8594 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8891 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8892 sections starting from zero, rather than making them consecutive.
8893 This makes subsequent reloc calculations easier, esp if the object
8894 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8895 allocate lcomm in .data rather than in .bss. It seems that some
8896 tools can't cope with a non-zero sized bss before linkage.
8898 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8900 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
8901 throughout. That enum no longer means what we thought it meant.

8922 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8924 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8925 .word is < -32768 or > 32767. The -J flag causes the error to be
8926 ignored. This is to catch over-sized switches generated by gcc on
8927 systems which don't support the broken .word hack.
8928 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8929 write.c (fixup_segment): check for signed .word overflow if
8930 WARN_SIGNED_OVERFLOW_WORD.
8932 * write.c (fixup_segment): fixed missing parens in expression
8933 checking for byte or word overflow.

8959 From Steve Chamberlain:
8960 Makefile.in: Handle m68*-*-coff*.
8961 read.c, read.h: add mult argument to s_space
8963 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8964 Motorola and MIT syntax; gas can now assemble either type of
8966 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8973 (fixup_segment) set fx_subsy to 0.
8974 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8976 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8979 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8981 * Makefile.in (LIBS): Include opcode library.

9008 * config/tc-m68k.c (init_table): Now const. Always include 68851
9009 data, so that "bc" is available to 68040 cache instructions.
9010 Added "tt0", "tt1", and 68ec030 variants.
9011 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9012 (enum _register): Added TT0, TT1.
9013 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9014 line number correctly in "internal error" messages. Don't print
9015 architecture-mismatch message for operand errors.

9040 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9041 has already been formatted (but may still contain %-characters).
9044 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9046 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9047 written with indirection on the last two operands, which can be
9048 either data or address registers. Added a new operand type 'r'
9049 which accepts either register type. Added '(' to notend stuff in
9050 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9069 their not having symbols associated.
9071 * tc-i960.c (norelax, instrument_branches): Default initializer is
9073 (linkrelax): Delete variable definition.

9386 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9387 copyrights to '92, changed some from Cygnus to FSF.
9389 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9391 * expr.c: If an expression is single comma, then return with
9392 SEG_ABSENT rather than an error - since the sparc front end does
9393 really strange things with things like fbge,a
9395 * as.h: include bfd.h if using many sections
9396 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9397 local labels didn't work.
9398 * listing.c (list_symbol_table): don't core dump when there's no
9400 * write.c, write.h: call fix_new with the right number of args on
9402 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9405 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9407 * app.c: MRI compatibility - allow single quote to start a string.
9408 * as.c: fix typo recently introduced.
9409 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9410 * expr.c: Much rewriting, to accomodate MRI syntax for
9411 expressions. Also easier to read now.
9412 * listing.c: Put back defuns
9413 * read.c: modified to accept MRI syntax, put back listing pseudo
9414 ops so that an assembler built with NO_LISTING ignores list ops
9416 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9417 machine is a SPARC or a 29K.
9418 * config/obj-aout.c: added s_sect pseudo op
9419 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9420 fill in the timestamp.
9421 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9422 anymore, define all the relocs which the tc-<x> bit will use so we
9423 can translate from them to the coff types.
9424 * config/tc-a29k.c: reloc_type isn't ane enum any more
9425 * config/tc-m68k.c: Added NO_RELOC definition.
9427 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9429 * Makefile.in: put header files before C source for TAGS; remove
9430 references to non-existent syscalls.h.
9432 * read.c, write.c subsegs.c: back out the .bss changes.
9434 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9436 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9440 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9442 * symbols.c (local_label_name): symbols now start with ^A.
9444 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9445 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9446 generate these sections. .align: will use NOP_OPCODE or 0
9447 for padding. This is just for being nice to the
9450 * expr.c (operand): changed to generate local label "\001L0"
9451 starting with a ^A so that it is recognized as a local label.
9453 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9455 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9456 i/o opcodes - inb, inw, outb and outw. string manipulation with
9457 att syntax - scmp, slod, smov, ssca, ssto.
9459 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9460 to just after .file .
9462 In obj_crawl_symbol_chain() where it tries to put the external
9463 symbols apart, with the condition:
9464 (!S_IS_DEFINED(symbolP) &&
9465 !S_IS_DEBUG(symbolP) &&
9466 !SF_GET_STATICS(symbolP))
9467 it was moving too many symbols out. So I switch it back to the
9469 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9471 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9472 so that we don't use the F_RELFLG which make the linker complain
9473 that somebody has stripped the relocation info.
9475 Also, the AIX ld program require that the relocation table
9476 is sorted by r_vaddr like the standard ATT assembler does.
9478 [he also changed the sizeof(struct ...)'s into the coff
9479 style FOOSZ macros. I'm not sure this is right, but I can't
9480 remember why. xoxorich.]
9482 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9484 * Makefile.in, configure.in, doc: use the doc. Build it, install
9487 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9489 * read.c: white space and comments only.
9491 * configure.in: use the new atof-ns32.c for ns32k.
9493 * write.c: comment change only.
9495 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9496 aren't yet integrated.
9498 * tc-i860.[hc]: blew off the dust. Something must still be done
9499 about conflicting relocation types.
9501 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9504 * tc-i960.c, tc-sparc.c: white space and comments only.
9506 * tc-a29k.h: delete duplicate macro definition.
9508 * new file atof-ns32k.c copied from hack's last unreleased gas.
9510 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9512 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9515 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9516 ChangeLog's prior to this are sketchy at best. I have logs.
9517 They just aren't ChangeLogs.
9524 version-control: never
