1012 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
1013 (tc_gen_reloc): Simplify. It's no longer necessary to set a
1014 reloc's addend field to zero for function symbols.
1015 (md_apply_fix): Simplify. For fixups which will require a SOM
1016 reloc, just clear out the necessary bits in the output file.

1020 * Makefile.in (BISON): Use bison -y, not bison.

1034 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1036 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
1037 it's better to use the one in libiberty.
1039 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1041 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
1042 change; it breaks the rs6000 support, and doesn't seem to be
1045 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1047 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

1053 rather than explicitly adding the frag address.
1054 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark

1056 used to be added by coff_add_linesym, removed Oct 7.
1057 (coff_adjust_section_syms): Ignore sections with no seginfo.
1059 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1061 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
1062 "stage" symlink to the appropriate stage* directory, and use it
1063 instead in the -B options.
1064 (comparison): Revert yesterday's change.

1071 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
1073 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
1074 for an embedded PIC switch expression, since the definition of
1075 S_IS_LOCAL was changed.

1079 * Makefile.in (comparison): When comparing as.new or gasp.new, try
1080 running the binary through sed to avoid differences due to

1083 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1085 ELF symbol size handling, based on code from Eric Youngdale:
1086 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an

1093 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
1095 (obj_elf_size): Deleted unused code. If size is non-reducible
1096 expression, allocate some storage for the sy_obj field and copy
1098 (elf_frob_symbol): New function. Computes sizes, calls
1099 ecoff_frob_symbol if appropriate.
1101 * write.c (fixup_segment): For i386 elf and coff (for now), don't

1148 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
1150 (diststuff): New target; builds DISTSTUFF.
1151 (realclean): Separate target, depend on clean and distclean, then
1153 * make-gas.com: Deleted.

1161 Add a space after "pc-relative" in the error message.
1162 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1163 BFD_RELOC_386_GOTOFF relocs.

1167 (TC_VALIDATE_FIX): New macro -- call it.
1168 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

1174 referring to PLT entries.
1175 * write.c (fix_new_internal): Initialize fx_plt to zero.
1176 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
1177 Don't adjust fx_offset by frag address, since S_GET_VALUE now
1178 includes the frag address.
1179 (fixup_segment): Changed local var PCREL to type int, added PLT.
1180 If PC-relative fixup refers to a PLT entry for a symbol in the
1181 current section, don't reduce it.

1188 (print_fixup): Added prototype. Show address on first line. Show
1189 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

1203 Show fx_r_type and fx_addsy fields.
1205 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1207 * configure.in: Set bfd_gas for all sparc targets in one place,
1208 instead of separately for each. Correctly handle user-supplied
1209 "--enable-bfd-gas" option.
1211 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1213 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
1216 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
1217 processing if add_symbol is undefined or in expr_section.

1221 (indent_level): No longer static.
1222 (print_symbol_value_1): Don't print frag address if it matches

1226 (print_expr_1): Fix whitespace before printing X_add_number.
1228 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1229 not symbol_new, for symbols holding expression values.
1230 * expr.h (make_expr_symbol): Move declaration here.
1231 * write.c (fix_new_exp): Handle O_add by creating an
1232 expression-valued symbol, and calling fix_new_exp recursively.
1233 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1234 undefined symbol and a constant, fold the constant into the fixup,
1235 and refer to the undefined symbol directly. Then process the
1236 fixup again from scratch.
1237 (write_object_file): Before calling adjust_reloc_syms, make a pass
1238 through the symbol list trying to resolve values.
1240 * write.c (print_fixup): New routine, for debugging.
1241 (write_relocs): Call bfd_install_relocation. Deleted various
1242 hacks for working around problems with bfd_perform_relocation.
1244 * Makefile.in (VERSION): Update to 2.4.90.
1246 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1248 * Makefile.in (gasp.o): Depends upon config.h.
1250 * config/tc-mips.c: Include subsegs.h.
1251 (md_apply_fix): If an unconditional b or bal overflows, and we are
1252 not assembling PIC code, replace it with a j or jal.
1254 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1255 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
1257 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1259 * write.c (write_relocs): Add file name and line number to
1260 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1261 RELOC_EXPANSION_POSSIBLE.
1263 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1265 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1266 here. Use them for deciding which PRINTF*LIKE macro definitions
1268 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1269 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1270 default definitions matching what we were doing before.
1271 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1272 always use the varargs form if not using stdarg. It's safe to
1273 always use vfprintf, because libiberty will provide it if the
1274 native system doesn't. Also, always make format be const.
1275 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
1277 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1290 (listing_newline): Check filename as well as line number when
1291 deciding whether to record it.
1292 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1293 false (if defined) as well as checking for reg_section.
1294 (listing_listing): Iterate fetching lines while line number is too
1295 low, and we haven't run off the end of the input file.
1297 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1299 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1301 * ecoff.c (ecoff_generate_asm_lineno): check if
1302 current_stabs_filename is NULL before strcmp.
1303 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
1306 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1308 * config/ho-*.h: Now-unused files deleted.
1310 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1311 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1312 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1313 zero. Don't call obj_frob_forward_symbol.
1314 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1315 X_add_number is zero.
1316 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1318 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1320 (strchr): Don't declare.
1321 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
1322 md_estimate_size_before_relax, md_ri_to_chars,
1323 md_create_short_jump, md_create_long_jump.
1324 (brtab_emit): Use data_section, not SEG_DATA.
1326 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1328 * config/vms-conf.h: new file, manually derived from conf.in.
1329 * config-gas.com: use it, and eliminate obsolete "host.h".

1333 * config/tc-ppc.c (ppc_current_block): New static variable.
1334 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
1335 ppc_current_block. Don't move around any stab symbol, just those
1337 (ppc_bs): Set ppc_current_block.
1338 (ppc_es): Clear ppc_current_block.
1339 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1340 from the csect of the enclosing block.
1342 * config/tc-mips.c (insns_since_cache_access): Remove.
1343 (append_insn): Remove setting of insns_since_cache_access, and
1344 special 4600 handling; it turns out not to be required.
1346 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1348 * config/tc-mips.c (md_shortopts): Remove E.
1349 (md_longopts): Add EB and EL.
1350 (md_parse_option): Handle -EB and -EL as separate options, rather
1351 than as a single -E option with an argument.
1353 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
1355 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
1356 involving global symbols too.
1358 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1360 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1362 * configure.in: Test for remove, not delete. Fix cross-assembler
1364 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1367 * read.c (pseudo_set, case O_symbol): If
1368 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1369 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1370 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1372 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1374 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1375 many others): new macros; values obtained from "DSTRECRDS.SDL".
1376 * config/obj-vms.h (various): use them.
1377 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1378 representation (only enum bitfields can avoid being bitstrings).
1379 (bitfield_suffix, setup_basic_type): new routines.
1380 (VMS_typedef_parse): use them. Now recognize bitfields of all
1381 integral types, not just type `int'. Caveat: the representation
1382 used for bitfields still does not work for objects placed in
1383 registers, and gcc's optimizer sometimes puts small structs there.
1385 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1387 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1388 bit from const_flag.
1389 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1390 (tc_frob_label): define this to call vms_check_for_special_label,
1391 and declare the latter.
1392 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1394 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1395 (vms_check_for_special_label): new routine (tc_frob_label).
1396 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1397 and `gcc2_compiled.' labels; they won't reach here any more.
1398 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1399 double', use `vax_g_doubles' flag to select type of double.
1400 (VMS_write_object_file) [traceback setup]: don't pass symbols
1401 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1402 and TBT_Routine_End functions.
1404 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
1406 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1407 S_GET_VALUE() to avoid many repeated function calls.
1408 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1409 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1410 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1411 be obsolete; gcc does it automatically for vms target. It's
1412 also misnamed, because it is for the "VAX C" run-time library,
1413 not the newer "DEC C" one which has much different startup code.]
1414 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1415 `S_GET_xxx(symbol) = new_value'.
1417 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1419 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1420 not &bfd_abs_section.
1422 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1424 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1426 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1428 * expr.c (expr): Don't reduce the difference of two symbols in the
1429 same frag if the symbols are not in normal sections.
1431 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1432 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1433 (obj_attach_unwind_info): Do not define. Not needed anymore.
1434 * config/tc-hppa.c: Delete whitespace at EOL.

2400 (DBG_S_C_REAL8_G, DBG_S_C_COMPLX8_G): G_float versions of
2401 REAL8 and COMPLX8; not used yet, because gcc outputs the same
2402 .stabs for `double' regardless of whether `-mg' is used.

2414 $8,%hi(foo); lw $8,%lo(foo)($8)'' work correctly.
2416 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2418 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
2419 to put a common symbol in a set.

2425 OBJ_BOUT if not BFD_ASSEMBLER.
2426 * config/aout_gnu.h (N_WEAKU, N_WEAKA, N_WEAKT, N_WEAKD, N_WEAKB):
2427 Define as in ../include/aout/aout64.h.

2443 Wed Jun 8 06:28:37 1994 Bill Cox (bill@cygnus.com)
2445 * Makefile.in (check): Delete as.new dependency, so that

2462 Fri Jun 3 23:35:36 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2464 * read.c (emit_expr): Use memset to zero out memory, rather than
2465 going through md_number_to_chars. This permits handling symbolic
2466 arguments when the size is larger than sizeof (valueT), if
2467 TC_CONS_FIX_NEW is prepared to handle the case (as it is on MIPS).
2469 Fri Jun 3 12:50:13 1994 David J. MacKenzie (djm@rtl.cygnus.com)

2518 m68040_control_regs, m68060_control_regs): New arrays.
2519 (control_regs): New pointer.
2520 (m68k_ip): Use control_regs instead of testing CPU every time.
2521 Use last_movec_reg too. In error messages, handle 68060, and
2522 print 68060 for mfloat, too.
2523 (m68k_init_after_args): Handle "68060". Use m68040up for making
2524 m68851 choice. Set control_regs.

2829 * config/tc-m68k.h (REGISTER_PREFIX): Always define if not already
2831 (OPTIONAL_REGISTER_PREFIX): Don't define.
2832 (REGISTER_PREFIX_OPTIONAL): If not already defined, define as zero
2833 or one depending on M68KCOFF.
2835 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
2836 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
2837 Define as macros instead of enumerators, since the Apollo compiler
2838 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
2840 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
2841 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
2842 R_DIR16, and R_DIR32 relocs.
2843 * config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
2844 Use Apollo versions.
2845 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,
2846 do include the optional header for Apollo target.
2847 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
2849 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
2850 can be used within a label name.
2852 * config/tc-m68k.h (m68k_init_after_args): Declare.
2853 (tc_init_after_args): Define as m68k_init_after_args.
2854 * config/tc-m68k.c (m68k_init_after_args): New function,
2855 containing one-shot code from md_assemble. Added warning for
2856 combination of 68040 and 68851.
2857 (md_assemble): Startup-time code deleted.
2859 Mon Apr 25 16:19:17 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

2871 and bfd_ecoff_set_regmasks to set the GP value and the register
2872 masks, rather than using the now obsolete fake .reginfo section.
2874 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2876 * listing.c (list_symbol_table): Don't print register symbols as
2879 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
2880 underscores, since symbol_new will already have done it.
2881 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
2883 * as.c (main): If tc_init_after_args is defined, invoke it after
2884 all arguments have been processed.
2886 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
2887 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
2888 section instead of .text. Call create_target_segments.
2889 * read.c (demand_copy_string): No longer static.
2891 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2893 * config/tc-mips.c (append_insn): Permit branches to be switched
2894 with the preceding instruction even if .set nobopt has been seen.
2895 .set nobopt actually controls whether to bring up an instruction
2896 from the branch target, which gas does not currently support.
2898 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2900 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

2913 * config/tc-sparc.c (md_section_align): Always round up to
2914 multiple of alignment power specified in bfd target vector.
2916 * gasp.c: Include ctype.h.

2937 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
2938 defaults for defined, private, and spnum fields for the

2949 address zero, insert a dummy line to compensate.
2951 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
2954 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2956 * expr.c (operand): Try to parse "0f" and "0b" sequences as
2957 floating point and binary numbers respectively; if it doesn't
2958 work, treat them as local labels.
2960 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
2961 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2963 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2965 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2966 source files from other directories into objects in the current
2967 directory, and specify PSECT attributes explicitly to linker.
2968 Also added missing label.
2969 * Makefile.in (stamp-mk.com): Reference new variable
2970 VMS_OTHER_OBJS for list of non-local object files, instead of

2985 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
2986 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
2987 argument, the reloc type.
2988 (load_register): Pass reloc type to macro_build for 'u'.
2989 (macro): Likewise. For M_LA_AB permit a difference expression
2990 when generating embedded PIC code between an arbitrary symbol and
2991 a symbol in the .text section.
2992 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2993 BFD_RELOC_PCREL_LO16 to be emitted.

3001 * subsegs.c (subsegs_begin): Call memset with args in the correct
3003 (subseg_get): Clear newly allocated seginfo, set its pointer slots
3004 to NULL instead of 0.

3008 * config/tc-hppa.c (pa_procend): Handle case where label was
3009 defined after the .proc directive.
3011 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
3012 procend for a procedure without a name.

3033 (hppa_tc_symbol): Likewise.
3035 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3036 elf_tc_make_sections stuff. It was there to support PA braindamage
3037 which has been fixed, and in the case of elf_tc_make_sections is
3038 redundant with elf_tc_final_processing.
3040 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3042 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

3047 * config/tc-mips.c (mips_ip): For case 'o', when generating
3048 embedded PIC code, accept the difference between two local symbols
3050 (mips_force_relocation): Only force a reloc to be generated for a
3052 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
3053 value into the file if the fixup will not generate a reloc.
3055 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
3057 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
3058 don't spew remainder of input file in error message.
3059 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3060 message with reloc type and try to process remainder of file.
3062 * doc/Makefile.in (install-info-as, install-info-gasp): New
3063 targets, now explicitly checking $(srcdir) for info files.
3064 (install-info): Depend on both of them; do nothing more.

3068 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
3070 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3072 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
3073 flag rather than signedp field. Only permit extended range if
3074 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
3075 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
3077 * config/tc-ppc.c (ppc_size): New static variable.
3078 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
3079 (md_begin): If an instruction has a size specific flag set, only
3080 add it if we are assembling that size.
3082 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3084 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3085 cross section PC relative relocs right for COFF and ELF.
3087 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3089 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
3090 (OBJ_PROCESS_STAB): Don't define.
3092 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3094 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3095 the type of symbol set symbols which happen to be in the absolute
3096 or undefined section.
3098 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
3100 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3101 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3102 and -many (all architectures).
3104 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3106 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
3107 involving a function symbol which is not a plabel to zero.
3108 (md_apply_fix): Never pass a function symbol to field_adjust.
3110 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3112 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3113 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3115 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3116 branch with an instruction that uses $at, in case the branch is
3118 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3119 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3120 to make it pcrel_offset.
3121 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3122 reloc->address; another gruesome hack to get gas reloc handling to
3125 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3127 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3130 (emit_insn): New function.
3131 (md_assemble): Call it.
3132 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3134 (lituse_pending): New variable. Set by anything that generates a
3135 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3136 tested by code that might want to emit a LITUSE reloc.
3137 (emit_unaligned_io): New function. Currently calls md_assemble,
3138 but it should eventually be converted to generate the insn itself
3139 and call emit_insn directly.
3140 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3141 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3142 emit_bis_r): Likewise.
3143 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3144 (alpha_ip, label get_macro): Don't emit the final instruction if
3146 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3147 unaligned memory access macros.
3148 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3149 the value can't be resolved.
3151 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3153 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3154 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3155 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3157 (mips_force_relocation): New function.
3158 (md_apply_fix): Set fixP->fx_done appropriately.
3159 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

3167 * config/tc-mips.c (enum mips_pic_level): New enum.
3168 (mips_pic): Change from int to enum mips_pic_level. Change all
3169 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3170 (load_address): Handle EMBEDDED_PIC.
3171 (macro): Handle EMBEDDED_PIC in all PIC cases.
3172 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3173 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3174 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3175 works). Do not permit -G with SVR4_PIC.
3176 (s_abicalls): Warn if -G was used, and force -G 0.
3177 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3178 anything but a.out, not just for ELF. For ECOFF, don't generate a
3179 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3181 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3183 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3185 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3186 parameters to avoid losing when compiling with HP CC.
3187 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3189 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3191 * Makefile.in (config-stamp): If `defs' is defined, emit a
3192 preprocessor directive to create a macro named by this value into
3193 config.new; don't explicitly go for BFD_ASSEMBLER.
3194 * configure.in: Define `defs', not `BFDDEF'. Set it to
3195 MANY_SEGMENTS for any obj-coffbfd target.
3196 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3197 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3199 (LOCAL_LOADLIBES): Deleted.
3200 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3201 * config/m88kcoff.mt (TDEFINES): Ditto.
3202 * config/ebmon29k.mt: Deleted.
3203 * config/h8300hds.mt: Deleted.
3204 * config/ic960coff.mt: Deleted.
3205 * config/sparc.mt: Deleted.
3206 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3207 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3208 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3209 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

3213 (OBJS): Add $(TE_OBJS).
3215 * config/obj-coff.c (obj_pseudo_table): Supply "section"
3218 * write.c (set_symtab): Define only if BFD_ASSEMBLER.
3220 Sun Mar 20 12:06:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3222 * Makefile.in (STAGESTUFF): Add gasp.new.
3224 Fri Mar 18 20:09:16 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3226 * write.c (symbol_table_frozen): New variable, to be set after
3227 bfd_set_symtab is called.
3228 (dump_section_relocs): Note whether a symbol is a section symbol
3230 (adjust_reloc_syms): For now, always supply an absolute symbol for
3231 fixups without symbols but not yet `done'. Use section_symbol to
3232 get the symbol, instead of going directly for abs_symbol.
3233 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3234 reloc is not a section symbol and is not in the symbol table.
3235 (set_symtab): New function, broken out from write_object_file.
3236 Counts symbol table instead of relying on an earlier count.
3237 (write_object_file): Call set_symtab, but do it after potentially
3238 invoking the *_frob_file macros. Don't bother counting symbols.
3239 Call symbol_remove, instead of expanding it in place. Moved the
3240 conditionalized `object_file_size' declaration down to
3241 conditionalized block where it's used. When using the absolute
3242 symbol for a fixup without a symbol, set sy_used_in_reloc.
3243 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3244 the correct symbol for the absolute section.
3246 * subsegs.c (section_symbol): Use symbol_new instead of
3247 symbol_make, since we may want it to go into the symbol table.
3248 Make the new symbol have internal linkage. If
3249 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3250 symbol with the newly created GAS symbol.
3251 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3252 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
3254 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
3256 * config/tc-sparc.c: Include subsegs.h.
3257 (in_signed_range): New function.
3259 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3260 (sparc_ip, label "immediate"): Reject constants for pcrel
3261 instructions only if the relocation type indicates a "call"
3262 instruction and the offset is within range of a "jmpl %g0". If
3263 it's not in range, use the absolute section symbol plus an offset.
3264 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3266 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3268 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3271 * configure.in: Eliminated all targets using obj-coff but not

5124 BFD_RELOC_MIPS_GPREL. Added new case a.
5125 (set_at, load_register, macro): Changed calls to macro_build to
5126 pass new argument for i, j and o cases.
5127 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

5348 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
5349 the table, require that the one without bit 0x1000000 set come

5408 * write.c (write_relocs): For relocs that are pc_relative and
5409 pcrel_offset and not partial_inplace, adjust reloc->addend to

5460 OPTIONAL_REGISTER_PREFIX if either is already defined.
5462 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5464 * configure.in: Set bfd_gas for all sparc targets. Added facility
5465 for keeping or rejecting configurations still under development;
5466 default is to assume production environment, and reject configs
5467 still being worked on. Mark Elf configurations (except sparc and
5468 i386) as developmental. Deleted cases matching some generic names
5469 in favor of more specific names. (E.g., when we get Alpha

5487 for functions only used within tc-hppa.c, likewise for structures,
5488 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5489 conditional code in a few small places.
5491 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5492 structures, global variables, forward declarations together.

5494 conditional code -- try to group conditional code together
5495 into a few places. Make all functions and variables which
5496 are only used within tc-hppa.c static. PARAMize all functions.
5497 Add comments to functions. Delete unused functions, variables,
5498 #defines, etc. Delete unused members within structures. Delete
5499 ldil;ble hacks -- it is believed they were installed to work
5500 around old gas bugs. Avoid using mixed case for local
5501 functions, variables, and structures. Fix formatting problems
5502 not found by GNU-indent. Add FIXME notices for things which
5503 should be worked on the near future. Delete lots of old
5504 useless (1.36 PA-SOM) code.

5533 a multiple of the section alignment rather than always a
5536 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

5579 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
5580 call strchr for each character to see if it is a special char,

5582 of text, data and bss sections to 4.
5583 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5585 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5586 ELF, since the ELF object format does not have these type of
5587 relocations. Change the abort into as as_bad and return
5588 BFD_RELOC_NONE to silence compiler warnings.
5589 (md_assemble): Keep track of the instruction size. Allow white
5590 space between the $ and the constant for compatibility with older
5591 gases and other assemblers.

6601 are also magic, and have special default flag settings.
6602 (obj_elf_frob_symbol): Since the return value from this function

6666 * Extensive changes to permit symbols to contain any expression
6667 type and to delay the computation of the expression until the
6668 value is actually needed. This permits setting symbols to values
6669 calculated based on object code size. Expressions were changed to
6670 no longer be in a section, to stop the overloading of segment and
6671 expression type that previously occurred.
6673 * as.c (big_section, pass1_section, diff_section, absent_section):
6675 (expr_section): Added (used for dummy symbols which hold

6761 to pop back to it. Handle unquoted section name as well as quoted
6762 section name. Don't crash on invalid strings.

6875 sy_resolved and sy_resolving single bit fields.
6876 * symbols.c (symbol_new): Don't initialize sy_forward field.

7938 references don't appear to work right.
7940 * as.h (const, volatile): Put these definitions back, and use
7943 * doc/as.texinfo: First pass at using new texinfo features --
7944 variables, conditional tests. Far from complete.

7970 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
7971 the bottom (make expands variables in dependencies when the
7972 dependencies are read, not when they are used).
7974 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
7975 a29k .bss section; the mondfe program doesn't like it.

7996 source directory, if that's not the current directory.
7998 * configure.in (per-host): Accept MIPS host with BSD version

8020 process relocs if there aren't any relocs to process. Avoids
8021 malloc/free bug on SCO too.

8024 avoid some redefinition complaints on some systems.
8025 (const, volatile): Don't need these conditionally defined if we
8026 use CONST and VOLATILE from ansidecl.h.
8027 (seg_name): Use CONST, not const.
8029 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
8031 * config/tc-mips.c: Reindented to GNU standards.
8033 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
8035 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
8036 (fixup_segment): Add a29k special case; the linker is not prepared
8037 to see a segment offset here.
8039 * app.c (do_scrub_next_char): Added new state, 10, modifying state
8040 9 to only keep a space in between identifier characters.
8042 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
8044 * Makefile.in: add dvi target; as-$(config).texinfo might live in
8045 srcdir, might be in objdir.
8047 * doc/Makefile.in: dvi depends on as.dvi

8065 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
8066 bignums, but don't emit error message.
8068 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
8070 * Makefile.in (targ-cpu.o): Depend on config.h.
8072 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
8074 * app.c (do_scrub_next_char): Added new state, 9, to avoid
8075 dropping a space immediately following an identifier.
8076 * expr.c, write.c: Rewrote assert expressions to not use multiple
8077 lines; I don't think that can be done portably.
8078 * config/tc-mips.c (macro): Use $AT if target register is zero in
8079 load instruction, which it can be for a floating point load.
8081 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

8089 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
8092 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
8093 z8k-opc.h, not z8k.h.
8095 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
8098 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8100 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
8102 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
8104 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

8153 prototypes for all static functions. Moved existing minimal
8154 debugging format support info #ifndef OBJ_ECOFF blocks.

8156 does not support a non sign extended high 16 bits reloc. Adjusted
8157 all callers accordingly.
8158 (tc_get_register): Renamed from get_register, and made non-static.

8203 * make-gas.com: Find obstack.obj if it's not in the current
8205 * read.c (s_ignore): Don't declare is_end_of_line. It's
8206 redundant, and triggers a VMS gcc compiler bug.
8208 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8209 current segment as an argument. (Ignored in all cases but VMS.)
8210 All callers and definitions changed.

8228 argument to s_ignore. Put "#if 0" around unused code.
8229 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
8230 Call elf_xstabs for .stabs and .xstabs operators.
8232 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
8234 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8237 * configure.in: mips-bsd configuration was missing format spec.
8240 * Makefile.in (Makefile): Depends on configure.in.
8242 * config/tc-mips.c (append_insn): Don't check for alignment of
8243 frag in memory; alignment of instructions in section is a separate

8263 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8264 constants are accepted, but symbolic values are not. GCC will not
8265 generate the latter currently.
8267 * frags.c (frag_init): New function.
8268 (zero_address_frag, bss_address_frag): Now initialized at run
8270 * as.c (main): Call frag_init.

8314 (fixup_segment): Make sure common-section symbols get treated the
8315 same as undefined symbols.
8316 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
8317 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from

8346 new section/subsection.
8348 * read.c: Don't include ctype.h.
8349 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
8350 for now; should be machine-dependent.
8352 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
8353 targets, forcing BFD use.

8375 (write_object_file) [! BFD_ASSEMBLER]: Call it.
8376 (relax_and_size_seg) [BFD_ASSEMBLER]: New function; relax section
8377 and set its size and flags.
8379 * struc-symbol.h (struct symbol) [BFD_ASSEMBLER]: Replace some

8521 md_relax_table): Use default zero initialization.
8522 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
8523 latter, instead of selecting with preprocessor conditionals.
8525 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8527 * configure.in: recognise all sparclite variants
8529 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

8532 accidentally changed to use subseg_change where it should have
8535 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8537 * expr.c (operand): If character other than comma or newline is a
8538 logical end-of-line character, use the newline case.
8539 From Eric Youngdale:
8540 (operand): Set X_add_number field for floating-point numbers.
8541 (operand): Treat zero byte as end-of-operand.
8543 * configure.in (per-target): Look for with_bfd_assembler option.
8544 For now, only accept "no", until the merge is done.
8546 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8547 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8548 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8549 * read.c: Finish conversion to S_* macros in the VMS only
8550 parts of the program. Add "const" modifier to hex_value.
8551 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
8553 * expr.c: Add "const" modifier to hex_value.
8554 * symbols.c: Finish conversion to S_* macros in the VMS only
8555 parts of the program. Add "const" modifier to
8556 md_[long,short]_jump_size. Remove declaration of const_flag
8557 (which will be declared in obj-vms.h).
8558 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8559 Fix arguments to VMS_write_object_file.
8560 * config-gas.com: New file. Script for VMS systems to set up the
8561 configuration to build gas for VMS, and create config.status.
8562 * make-gas.com: Redone to work with new scheme.
8563 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8565 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8566 will swap bytes if needed on a big endian system. Use throughout
8568 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8569 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8570 types of malformed stabs. Change parsing algorithm so that we are
8571 more certain of having all of the information that we need on hand.
8572 * obj-vms.c (final_forward_reference): New function, used to help
8573 resolve the data types of as many struct elements as possible
8574 when some part of the struct is not fully defined by the compiler.
8575 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
8577 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8578 as symbols as well in the object file. Look for external functions
8579 that start with "__vt.", and turn them into variables, since the
8580 g++ compiler is incapable of doing this.
8581 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8583 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8584 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8585 have the name of the source file yet.
8586 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8588 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8590 * read.c (s_data): Always use "data_section", since it'll map to
8591 SEG_DATA or SEG_E1 if needed.
8592 (s_lcomm): Likewise with bss_section.
8593 (s_fill): Use memset, not bzero.
8595 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8614 otherwise, use seg_name array.
8615 (seg_name): Declare only if not BFD_ASSEMBLER.
8616 (section_alignment): Declare only if not BFD_ASSEMBLER.
8617 (big_section, reg_section, pass1_section, diff_section,
8618 absent_section, text_section, data_section, bss_section): If
8619 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8620 mapping to segT enum values.
8621 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8622 if these are used or defined, if BFD_ASSEMBLER.
8623 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8624 subseg_new split into two functions.
8625 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8627 * as.h (volatile): Don't define if already defined.
8628 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8630 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8631 declare with format attribute for -Wformat checking.
8633 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8635 * app.c, config/tc-*.c: Don't include read.h, since it is already
8638 * These are based on patches from Minh Tran-le
8639 <mtranle@paris.intellicorp.com>.
8640 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8641 obj_format coffbfd and gas_target i386coff for target.
8642 (i[34]86-*-isc*): New host (uses sysv).
8643 * config/i386aix.mt: Removed (no longer used).
8644 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8646 (LDFLAGS): Added, defined as -shlib.
8647 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8648 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8649 (DOT_LABEL_PREFIX): Define.
8650 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8651 name rather than L0\001.
8652 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8654 * symbols.c, symbols.h (local_bss_counter): Removed.
8655 * write.c (write_object_file): bss no longer uses
8656 local_bss_counter. Pass correct data and bss size to
8657 VMS_write_object_file.

8663 (size_section): Restored sanity check.
8664 (do_relocs_for): Base section address on s_paddr rather than
8665 computing it. Adjust a29k R_IHIHALF special case to account for
8666 section paddr (used to require paddr to be zero). If there are no
8667 reclos, set s_relptr to 0. Set relocation size in object_headers.
8668 (fill_section): Always set s_vaddr here, removing
8669 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8670 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8671 Set STYP_INFO for .comment.
8672 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
8673 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

8675 H_{SET,GET}_* macros.
8676 (do_linenos_for): Set lineno size in object_headers.
8677 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8678 set s_vaddr here. If string_byte_count remains 4, set it back to
8679 0, and only write strings out if there are some. Call
8680 fill_section before do_relocs_for and do_linenos_for.
8681 (obj_coff_section): Handle optional quoted second argument giving
8682 section characteristics.
8683 (obj_coff_bss): Added to handle .bss.
8684 (obj_coff_ident): Added to handle .ident (puts string in .comment
8686 (obj_coff_lcomm): Put common symbols in .bss, not .data.
8687 (fixup_mdeps): Change to segment. Call frag_wane after
8689 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8690 adjustment (already happened only for common symbols, but this is

8704 (do_scrub_next_char): For \", return " not '.
8705 (symbol_chars): Now const.
8707 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8708 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8710 * config/obj-coff.h: Don't use #elif.
8712 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8713 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
8715 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
8717 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

8739 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8740 using ZERO_BASED_SEGMENTS.
8741 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8742 never set segment address for SEG_E2 (.bss) and don't write out
8743 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8744 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8745 definitions, and don't merge tags with non-tags. Check for .bf
8746 rather than just checking whether the second character is b and
8747 the third character is f.
8748 (obj_coff_val): gcc can generate values which we don't handle
8749 correctly; discard information for now, since it only affects the
8750 debugging information.
8751 (tag_find_or_name): Don't insert tags in the symbol table.
8752 (yank_symbols): Don't merge labels.
8753 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8891 * all files: Whitespace changes for GNU indentation style, done by
8892 GNU `indent'. Some cleanup still needed, especially of comments.
8894 * configure.in: No te-386bsd.h file exists; don't try to use it.
8896 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
8898 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
8899 could be doing emulation.
8901 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8904 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8929 * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
8930 comment_chars, line_comment_chars and line_seperator_chars
8931 consistently const, and always initialized them. Included read.h.
8933 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8935 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8936 constant will not fit in an immediate field.
8937 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
8939 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
8941 * obj-coff.c (callj_table): Delete global variable.

8948 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
8949 with a single set using PARAMS macro.
8951 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length

8956 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
8957 so widening works consistently.
8959 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
8961 * version.c: Put conditional "const" before version_string, not
8962 before dummy function for VMS. Now version 1.91.03.
8964 * app.c (do_scrub_next_char): Need double-\ before `000' to show
8965 printed rep of null character.
8967 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
8969 * obj-coffbfd.c (write_object_file): check return value of
8972 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8974 * Support for i386-sysv.
8975 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
8976 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
8977 be used to set them all to zero as was done before.
8978 (fill_section): segment addresses now set in write_object_file.
8979 (fill_section): Don't set STYP_NOLOAD for .bss section.
8980 (fixup_segment): 386 uses strange common symbol format.
8981 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
8982 compatibility with SVR3.2 linker.
8983 * configure.in: i386-sysv and i386-sco use coffbfd.
8985 * app.c (do_scrub_next_char): discard whitespace after a label.

8994 fix i960+non-bfd coff bit rot.
8995 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
8996 support for C source listings. (obj_coff_endef): look in the right

8999 * tc-m68k.c (get_num): make it work for all segments, not just the
9002 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
9004 * configure.in: recognize i386-*-bsd emulation.

9013 * tc-z8k.c: lots of bug fixes
9015 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
9017 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
9018 #elif, since it is not supported by old compilers.
9019 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
9020 couple of expressions in tc-m68k.c.
9022 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9024 * read.c (cons): If NO_RELOC is defined, use it.
9026 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
9028 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
9030 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
9031 local labels to start with a .) and set REGISTER_PREFIX to %.
9032 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
9034 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

9048 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
9050 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9051 sections starting from zero, rather than making them consecutive.
9052 This makes subsequent reloc calculations easier, esp if the object
9053 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9054 allocate lcomm in .data rather than in .bss. It seems that some
9055 tools can't cope with a non-zero sized bss before linkage.
9057 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9059 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
9060 throughout. That enum no longer means what we thought it meant.

9063 "-mno-688[58]1" options.
9065 * tc-m68k.c: Added CPU32 support.

9074 Change LIBDEPS dependence to LIBS.
9076 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
9078 * Makefile.in (install): if $(tooldir) exists, install as in
9081 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
9083 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9084 .word is < -32768 or > 32767. The -J flag causes the error to be
9085 ignored. This is to catch over-sized switches generated by gcc on
9086 systems which don't support the broken .word hack.
9087 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9088 write.c (fixup_segment): check for signed .word overflow if
9089 WARN_SIGNED_OVERFLOW_WORD.
9091 * write.c (fixup_segment): fixed missing parens in expression
9092 checking for byte or word overflow.
9094 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
9095 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
9096 WARN_SIGNED_OVERFLOW_WORD.

9104 * obj-coffbfd.h : added stuff
9105 * tc-i386.c (tc_coff_fix2rtype): new function
9106 * tc-i386.h : new coff defines
9108 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
9110 * input-scrub.c (input_scrub_push): call input_file_begin, not
9112 messages.c (as_perror): print ": " between the passed in error and
9113 the strerror, like perror does.
9115 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
9117 * Makefile.in: use gas_target instead of modifying target_cpu.
9118 From Steve Chamberlain:
9119 Makefile.in: Handle m68*-*-coff*.
9120 read.c, read.h: add mult argument to s_space
9122 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
9123 Motorola and MIT syntax; gas can now assemble either type of
9125 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
9126 From Steve Chamberlain:
9127 m68kcoff.mt: for m68k COFF.
9128 obj-coffbfd.c: (fixup_mdeps) added

9131 (write_object_file) call fixup_mdeps
9132 (fixup_segment) set fx_subsy to 0.
9133 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9135 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9138 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9140 * Makefile.in (LIBS): Include opcode library.
9142 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
9144 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers

9162 tc-i960.c (md_ri_to_chars): Always output bout object file in
9163 little endian byte order (used to use endianness of host).
9165 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9167 * config/tc-m68k.c (init_table): Now const. Always include 68851
9168 data, so that "bc" is available to 68040 cache instructions.
9169 Added "tt0", "tt1", and 68ec030 variants.
9170 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9171 (enum _register): Added TT0, TT1.
9172 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9173 line number correctly in "internal error" messages. Don't print
9174 architecture-mismatch message for operand errors.
9176 From Colin Smith (colin@wrs.com):
9177 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
9178 than install_operand.

9182 * listing.c (buffer_line): rewind to the start of include
9183 files, they might be included twice.

9190 one element of a family.
9192 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
9194 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
9195 so that we can assemble hand-written libgcc code.
9197 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9199 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9200 has already been formatted (but may still contain %-characters).
9203 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9205 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9206 written with indirection on the last two operands, which can be
9207 either data or address registers. Added a new operand type 'r'
9208 which accepts either register type. Added '(' to notend stuff in
9209 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
9211 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

9224 defined, call it. Change segments before calling fixup_segment.
9225 (relax_align): If linkrelax, provide extra padding.
9227 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
9228 their not having symbols associated.
9230 * tc-i960.c (norelax, instrument_branches): Default initializer is
9232 (linkrelax): Delete variable definition.

9255 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
9256 being used with args swapped, causing occasional lossage when
9257 refilling buffers after an include file.
9259 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
9261 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
9262 version. Discard bogus DONTDEF version.
9263 (as_warn, as_bad, as_fatal): Likewise.
9265 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
9267 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
9268 selected architecture, print a message saying so and listing what

9290 * read.c (s_fill): make the .fill size clamped error a warn and
9291 fix bug where 0's were always placed.
9293 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
9294 two bytes of any constant with 0xff:

9298 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
9299 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

9313 * configure.in (mips host): Accept "ultrix" with version number.
9315 * expr.c (floating_constant): Separate "=-" to avoid confusing
9316 ancient or broken compilers.
9318 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
9319 processor/opcode mismatch, so reword the error message.
9320 (md_assemble): If no CPU has been set (even if FPU/PMMU
9321 characteristics have been), default to 68020. Don't need extra
9322 quotes around error string.
9324 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
9326 * read.c (potable): Revert sac's incorrect change made Jul 13.

9396 * write.c (write_object_file): If a.out don't use the old way for
9398 * config/obj-a.out (s_sect): complain if the user tries to use a
9399 subsegment with a value which might interfere with out -R hackery.
9400 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
9401 rather than use ugly if tree. (init_regtable): insert register
9402 names into symbol table.
9404 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
9406 * write.c (write_object_file): keep the fix_tail clean, which
9407 fixes a bug in -R where relocations were being lost.
9409 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
9411 * configure.in: recognize m680x0 as having sun3 emulation mode for

9434 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9436 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
9437 calc the base of relocs correctly.
9438 * tc-a29k.c (parse_operand): allow expressions to be in any section.
9440 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
9442 * as.c, write.c: use -K rather than -k for the broken word warning

9453 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9455 * write.c (write_object_file): For b.out format, round up section
9456 start addresses to match required alignment.
9458 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9460 * Makefile.in (install): Install into $(tooldir)/bin, since that's
9461 where gcc looks for it.
9463 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
9465 * Makefile.in: Changed some lines to be less confusing for some
9468 * input-file.c: Conditionalize on _IOFBF, not VMS.
9470 * read.c, write.c: Change a series of ifdef/elif to

9500 local_labels_fb must be < 10.
9502 * symbols.c: remove local_labels_dollar, replace with a function
9503 interface for a sparse array. All users adjusted.
9505 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
9507 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

9528 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9531 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9533 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9535 * expr.c (operand): if can't work out what sort of operand it is,
9536 then look through FLT_CHARS for a hint.
9538 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9540 * Makefile.in, configure.in: removed traces of namesubdir,
9541 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9542 copyrights to '92, changed some from Cygnus to FSF.
9544 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9545 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9546 copyrights to '92, changed some from Cygnus to FSF.
9548 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9550 * expr.c: If an expression is single comma, then return with
9551 SEG_ABSENT rather than an error - since the sparc front end does
9552 really strange things with things like fbge,a
9554 * as.h: include bfd.h if using many sections
9555 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9556 local labels didn't work.
9557 * listing.c (list_symbol_table): don't core dump when there's no
9559 * write.c, write.h: call fix_new with the right number of args on
9561 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9564 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9566 * app.c: MRI compatibility - allow single quote to start a string.
9567 * as.c: fix typo recently introduced.
9568 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9569 * expr.c: Much rewriting, to accomodate MRI syntax for
9570 expressions. Also easier to read now.
9571 * listing.c: Put back defuns
9572 * read.c: modified to accept MRI syntax, put back listing pseudo
9573 ops so that an assembler built with NO_LISTING ignores list ops
9575 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9576 machine is a SPARC or a 29K.
9577 * config/obj-aout.c: added s_sect pseudo op
9578 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9579 fill in the timestamp.
9580 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9581 anymore, define all the relocs which the tc-<x> bit will use so we
9582 can translate from them to the coff types.
9583 * config/tc-a29k.c: reloc_type isn't ane enum any more
9584 * config/tc-m68k.c: Added NO_RELOC definition.
9586 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9588 * Makefile.in: put header files before C source for TAGS; remove
9589 references to non-existent syscalls.h.
9591 * read.c, write.c subsegs.c: back out the .bss changes.
9593 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9595 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9599 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9601 * symbols.c (local_label_name): symbols now start with ^A.
9603 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9604 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9605 generate these sections. .align: will use NOP_OPCODE or 0
9606 for padding. This is just for being nice to the
9609 * expr.c (operand): changed to generate local label "\001L0"
9610 starting with a ^A so that it is recognized as a local label.
9612 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9614 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9615 i/o opcodes - inb, inw, outb and outw. string manipulation with
9616 att syntax - scmp, slod, smov, ssca, ssto.
9618 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9619 to just after .file .
9621 In obj_crawl_symbol_chain() where it tries to put the external
9622 symbols apart, with the condition:
9623 (!S_IS_DEFINED(symbolP) &&
9624 !S_IS_DEBUG(symbolP) &&
9625 !SF_GET_STATICS(symbolP))
9626 it was moving too many symbols out. So I switch it back to the
9628 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9630 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9631 so that we don't use the F_RELFLG which make the linker complain
9632 that somebody has stripped the relocation info.
9634 Also, the AIX ld program require that the relocation table
9635 is sorted by r_vaddr like the standard ATT assembler does.
9637 [he also changed the sizeof(struct ...)'s into the coff
9638 style FOOSZ macros. I'm not sure this is right, but I can't
9639 remember why. xoxorich.]
9641 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9643 * Makefile.in, configure.in, doc: use the doc. Build it, install
9646 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9648 * read.c: white space and comments only.
9650 * configure.in: use the new atof-ns32.c for ns32k.
9652 * write.c: comment change only.
9654 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9655 aren't yet integrated.
9657 * tc-i860.[hc]: blew off the dust. Something must still be done
9658 about conflicting relocation types.
9660 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9663 * tc-i960.c, tc-sparc.c: white space and comments only.
9665 * tc-a29k.h: delete duplicate macro definition.
9667 * new file atof-ns32k.c copied from hack's last unreleased gas.
9669 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9671 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9674 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9675 ChangeLog's prior to this are sketchy at best. I have logs.
9676 They just aren't ChangeLogs.
9683 version-control: never
