1006 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
1007 (tc_gen_reloc): Simplify. It's no longer necessary to set a
1008 reloc's addend field to zero for function symbols.
1009 (md_apply_fix): Simplify. For fixups which will require a SOM
1010 reloc, just clear out the necessary bits in the output file.
1012 Fri Oct 14 19:06:46 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1014 * Makefile.in (BISON): Use bison -y, not bison.

1028 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1030 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
1031 it's better to use the one in libiberty.
1033 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1035 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
1036 change; it breaks the rs6000 support, and doesn't seem to be
1039 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1041 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

1047 rather than explicitly adding the frag address.
1048 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
1049 the end of the line numbers; this replaces the zero entry which
1050 used to be added by coff_add_linesym, removed Oct 7.
1051 (coff_adjust_section_syms): Ignore sections with no seginfo.
1053 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1055 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
1056 "stage" symlink to the appropriate stage* directory, and use it
1057 instead in the -B options.
1058 (comparison): Revert yesterday's change.
1060 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

1065 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
1067 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
1068 for an embedded PIC switch expression, since the definition of
1069 S_IS_LOCAL was changed.
1071 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1073 * Makefile.in (comparison): When comparing as.new or gasp.new, try
1074 running the binary through sed to avoid differences due to
1075 "stage1" or "stage2" having been written into the binary.
1077 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1079 ELF symbol size handling, based on code from Eric Youngdale:
1080 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an
1081 expression pointer to the symbol structure, used for `size'
1082 expressions that couldn't be reduced to constants when initially
1084 (elf_frob_symbol): Declare.
1085 (obj_frob_symbol): Call elf_frob_symbol always, rather than

1087 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
1089 (obj_elf_size): Deleted unused code. If size is non-reducible
1090 expression, allocate some storage for the sy_obj field and copy
1092 (elf_frob_symbol): New function. Computes sizes, calls
1093 ecoff_frob_symbol if appropriate.
1095 * write.c (fixup_segment): For i386 elf and coff (for now), don't
1096 add in value of symbol from another defined section of the file.
1098 Fri Oct 7 17:54:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

1142 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
1144 (diststuff): New target; builds DISTSTUFF.
1145 (realclean): Separate target, depend on clean and distclean, then
1147 * make-gas.com: Deleted.
1149 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
1150 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
1152 (i386_operand): Don't look up section symbol for
1154 (reloc): Always permit return of 8- and 16-bit relocation types.
1155 Add a space after "pc-relative" in the error message.
1156 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1157 BFD_RELOC_386_GOTOFF relocs.

1161 (TC_VALIDATE_FIX): New macro -- call it.
1162 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

1167 * write.h (struct fix): Added new bitfield fx_plt, for fixups
1168 referring to PLT entries.
1169 * write.c (fix_new_internal): Initialize fx_plt to zero.
1170 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
1171 Don't adjust fx_offset by frag address, since S_GET_VALUE now
1172 includes the frag address.
1173 (fixup_segment): Changed local var PCREL to type int, added PLT.
1174 If PC-relative fixup refers to a PLT entry for a symbol in the
1175 current section, don't reduce it.

1181 and after processing.
1182 (print_fixup): Added prototype. Show address on first line. Show
1183 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

1197 Show fx_r_type and fx_addsy fields.
1199 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1201 * configure.in: Set bfd_gas for all sparc targets in one place,
1202 instead of separately for each. Correctly handle user-supplied
1203 "--enable-bfd-gas" option.
1205 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1207 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
1210 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
1211 processing if add_symbol is undefined or in expr_section.

1213 constant-valued symbol, convert to O_symbol and re-reduce.
1214 (S_GET_VALUE): If symbol needs resolving, resolve it.
1215 (indent_level): No longer static.
1216 (print_symbol_value_1): Don't print frag address if it matches
1217 zero_address_frag. Don't print "resolving" if already resolved.
1218 Print segment name. Don't call print_expr_1 on an undefined
1220 (print_expr_1): Fix whitespace before printing X_add_number.
1222 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1223 not symbol_new, for symbols holding expression values.
1224 * expr.h (make_expr_symbol): Move declaration here.
1225 * write.c (fix_new_exp): Handle O_add by creating an
1226 expression-valued symbol, and calling fix_new_exp recursively.
1227 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1228 undefined symbol and a constant, fold the constant into the fixup,
1229 and refer to the undefined symbol directly. Then process the
1230 fixup again from scratch.
1231 (write_object_file): Before calling adjust_reloc_syms, make a pass
1232 through the symbol list trying to resolve values.
1234 * write.c (print_fixup): New routine, for debugging.
1235 (write_relocs): Call bfd_install_relocation. Deleted various
1236 hacks for working around problems with bfd_perform_relocation.
1238 * Makefile.in (VERSION): Update to 2.4.90.
1240 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1242 * Makefile.in (gasp.o): Depends upon config.h.
1244 * config/tc-mips.c: Include subsegs.h.
1245 (md_apply_fix): If an unconditional b or bal overflows, and we are
1246 not assembling PIC code, replace it with a j or jal.
1248 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1249 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
1251 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1253 * write.c (write_relocs): Add file name and line number to
1254 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1255 RELOC_EXPANSION_POSSIBLE.
1257 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1259 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1260 here. Use them for deciding which PRINTF*LIKE macro definitions
1262 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1263 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1264 default definitions matching what we were doing before.
1265 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1266 always use the varargs form if not using stdarg. It's safe to
1267 always use vfprintf, because libiberty will provide it if the
1268 native system doesn't. Also, always make format be const.
1269 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
1271 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1273 * config/tc-mips.c (load_register): Always use addiu when adding a

1282 * listing.c: Bugfixes based in part on patches from Paul
1284 (listing_newline): Check filename as well as line number when
1285 deciding whether to record it.
1286 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1287 false (if defined) as well as checking for reg_section.
1288 (listing_listing): Iterate fetching lines while line number is too
1289 low, and we haven't run off the end of the input file.
1291 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1293 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1295 * ecoff.c (ecoff_generate_asm_lineno): check if
1296 current_stabs_filename is NULL before strcmp.
1297 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
1300 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1302 * config/ho-*.h: Now-unused files deleted.
1304 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1305 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1306 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1307 zero. Don't call obj_frob_forward_symbol.
1308 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1309 X_add_number is zero.
1310 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1312 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1314 (strchr): Don't declare.
1315 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
1316 md_estimate_size_before_relax, md_ri_to_chars,
1317 md_create_short_jump, md_create_long_jump.
1318 (brtab_emit): Use data_section, not SEG_DATA.
1320 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1322 * config/vms-conf.h: new file, manually derived from conf.in.
1323 * config-gas.com: use it, and eliminate obsolete "host.h".
1325 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1327 * config/tc-ppc.c (ppc_current_block): New static variable.
1328 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
1329 ppc_current_block. Don't move around any stab symbol, just those
1331 (ppc_bs): Set ppc_current_block.
1332 (ppc_es): Clear ppc_current_block.
1333 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1334 from the csect of the enclosing block.
1336 * config/tc-mips.c (insns_since_cache_access): Remove.
1337 (append_insn): Remove setting of insns_since_cache_access, and
1338 special 4600 handling; it turns out not to be required.
1340 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1342 * config/tc-mips.c (md_shortopts): Remove E.
1343 (md_longopts): Add EB and EL.
1344 (md_parse_option): Handle -EB and -EL as separate options, rather
1345 than as a single -E option with an argument.
1347 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
1349 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
1350 involving global symbols too.
1352 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1354 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1356 * configure.in: Test for remove, not delete. Fix cross-assembler
1358 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1361 * read.c (pseudo_set, case O_symbol): If
1362 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1363 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1364 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1366 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1368 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1369 many others): new macros; values obtained from "DSTRECRDS.SDL".
1370 * config/obj-vms.h (various): use them.
1371 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1372 representation (only enum bitfields can avoid being bitstrings).
1373 (bitfield_suffix, setup_basic_type): new routines.
1374 (VMS_typedef_parse): use them. Now recognize bitfields of all
1375 integral types, not just type `int'. Caveat: the representation
1376 used for bitfields still does not work for objects placed in
1377 registers, and gcc's optimizer sometimes puts small structs there.
1379 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1381 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1382 bit from const_flag.
1383 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1384 (tc_frob_label): define this to call vms_check_for_special_label,
1385 and declare the latter.
1386 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1388 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1389 (vms_check_for_special_label): new routine (tc_frob_label).
1390 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1391 and `gcc2_compiled.' labels; they won't reach here any more.
1392 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1393 double', use `vax_g_doubles' flag to select type of double.
1394 (VMS_write_object_file) [traceback setup]: don't pass symbols
1395 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1396 and TBT_Routine_End functions.
1398 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
1400 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1401 S_GET_VALUE() to avoid many repeated function calls.
1402 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1403 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1404 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1405 be obsolete; gcc does it automatically for vms target. It's
1406 also misnamed, because it is for the "VAX C" run-time library,
1407 not the newer "DEC C" one which has much different startup code.]
1408 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1409 `S_GET_xxx(symbol) = new_value'.
1411 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1413 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1414 not &bfd_abs_section.
1416 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1418 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1420 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1422 * expr.c (expr): Don't reduce the difference of two symbols in the
1423 same frag if the symbols are not in normal sections.
1425 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1426 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1427 (obj_attach_unwind_info): Do not define. Not needed anymore.
1428 * config/tc-hppa.c: Delete whitespace at EOL.
1429 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1430 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1431 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1432 fixups, store 32bits of unwind information in the fx_addnumber
1434 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY

2394 (DBG_S_C_REAL8_G, DBG_S_C_COMPLX8_G): G_float versions of
2395 REAL8 and COMPLX8; not used yet, because gcc outputs the same
2396 .stabs for `double' regardless of whether `-mg' is used.

2408 $8,%hi(foo); lw $8,%lo(foo)($8)'' work correctly.
2410 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2412 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
2413 to put a common symbol in a set.

2419 OBJ_BOUT if not BFD_ASSEMBLER.
2420 * config/aout_gnu.h (N_WEAKU, N_WEAKA, N_WEAKT, N_WEAKD, N_WEAKB):
2421 Define as in ../include/aout/aout64.h.

2437 Wed Jun 8 06:28:37 1994 Bill Cox (bill@cygnus.com)
2439 * Makefile.in (check): Delete as.new dependency, so that

2456 Fri Jun 3 23:35:36 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2458 * read.c (emit_expr): Use memset to zero out memory, rather than
2459 going through md_number_to_chars. This permits handling symbolic

2512 m68040_control_regs, m68060_control_regs): New arrays.
2513 (control_regs): New pointer.
2514 (m68k_ip): Use control_regs instead of testing CPU every time.
2515 Use last_movec_reg too. In error messages, handle 68060, and
2516 print 68060 for mfloat, too.
2517 (m68k_init_after_args): Handle "68060". Use m68040up for making
2518 m68851 choice. Set control_regs.

2830 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
2831 Define as macros instead of enumerators, since the Apollo compiler
2832 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
2834 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
2835 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
2836 R_DIR16, and R_DIR32 relocs.
2837 * config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
2838 Use Apollo versions.
2839 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,
2840 do include the optional header for Apollo target.
2841 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
2843 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
2844 can be used within a label name.
2846 * config/tc-m68k.h (m68k_init_after_args): Declare.
2847 (tc_init_after_args): Define as m68k_init_after_args.
2848 * config/tc-m68k.c (m68k_init_after_args): New function,
2849 containing one-shot code from md_assemble. Added warning for
2850 combination of 68040 and 68851.
2851 (md_assemble): Startup-time code deleted.
2853 Mon Apr 25 16:19:17 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2855 * doc/Makefile.in (clean, distclean): Remove asconfig.texi.

2865 and bfd_ecoff_set_regmasks to set the GP value and the register
2866 masks, rather than using the now obsolete fake .reginfo section.
2868 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2870 * listing.c (list_symbol_table): Don't print register symbols as
2873 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
2874 underscores, since symbol_new will already have done it.
2875 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
2877 * as.c (main): If tc_init_after_args is defined, invoke it after
2878 all arguments have been processed.
2880 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
2881 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
2882 section instead of .text. Call create_target_segments.
2883 * read.c (demand_copy_string): No longer static.
2885 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2887 * config/tc-mips.c (append_insn): Permit branches to be switched
2888 with the preceding instruction even if .set nobopt has been seen.
2889 .set nobopt actually controls whether to bring up an instruction
2890 from the branch target, which gas does not currently support.
2892 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2894 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only
2895 when BFD_ASSEMBLER is not defined, and all conditionals relating

2907 * config/tc-sparc.c (md_section_align): Always round up to
2908 multiple of alignment power specified in bfd target vector.
2910 * gasp.c: Include ctype.h.

2931 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
2932 defaults for defined, private, and spnum fields for the

2934 not reset the segment if just updating a space.
2935 (pa_spaces_begin): Set BFD section flags for all built-in
2938 Fri Apr 15 10:51:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

2941 (add_procedure): Set first_proc_ptr if it hasn't been set.
2942 (ecoff_build_lineno): If the first procedure does not start at
2943 address zero, insert a dummy line to compensate.
2945 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
2948 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2950 * expr.c (operand): Try to parse "0f" and "0b" sequences as
2951 floating point and binary numbers respectively; if it doesn't
2952 work, treat them as local labels.
2954 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
2955 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2957 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2959 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2960 source files from other directories into objects in the current
2961 directory, and specify PSECT attributes explicitly to linker.
2962 Also added missing label.
2963 * Makefile.in (stamp-mk.com): Reference new variable
2964 VMS_OTHER_OBJS for list of non-local object files, instead of

2979 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
2980 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
2981 argument, the reloc type.
2982 (load_register): Pass reloc type to macro_build for 'u'.
2983 (macro): Likewise. For M_LA_AB permit a difference expression
2984 when generating embedded PIC code between an arbitrary symbol and
2985 a symbol in the .text section.
2986 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2987 BFD_RELOC_PCREL_LO16 to be emitted.

2995 * subsegs.c (subsegs_begin): Call memset with args in the correct
2997 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2998 to NULL instead of 0.

3002 * config/tc-hppa.c (pa_procend): Handle case where label was
3003 defined after the .proc directive.
3005 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
3006 procend for a procedure without a name.

3027 (hppa_tc_symbol): Likewise.
3029 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3030 elf_tc_make_sections stuff. It was there to support PA braindamage
3031 which has been fixed, and in the case of elf_tc_make_sections is
3032 redundant with elf_tc_final_processing.
3034 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3036 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

3041 * config/tc-mips.c (mips_ip): For case 'o', when generating
3042 embedded PIC code, accept the difference between two local symbols
3044 (mips_force_relocation): Only force a reloc to be generated for a
3046 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
3047 value into the file if the fixup will not generate a reloc.
3049 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
3051 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
3052 don't spew remainder of input file in error message.
3053 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3054 message with reloc type and try to process remainder of file.
3056 * doc/Makefile.in (install-info-as, install-info-gasp): New
3057 targets, now explicitly checking $(srcdir) for info files.
3058 (install-info): Depend on both of them; do nothing more.
3060 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
3062 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
3064 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3066 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
3067 flag rather than signedp field. Only permit extended range if
3068 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
3069 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
3071 * config/tc-ppc.c (ppc_size): New static variable.
3072 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
3073 (md_begin): If an instruction has a size specific flag set, only
3074 add it if we are assembling that size.
3076 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3078 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3079 cross section PC relative relocs right for COFF and ELF.
3081 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3083 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
3084 (OBJ_PROCESS_STAB): Don't define.
3086 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3088 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3089 the type of symbol set symbols which happen to be in the absolute
3090 or undefined section.
3092 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
3094 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3095 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3096 and -many (all architectures).
3098 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3100 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
3101 involving a function symbol which is not a plabel to zero.
3102 (md_apply_fix): Never pass a function symbol to field_adjust.
3104 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3106 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3107 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3109 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3110 branch with an instruction that uses $at, in case the branch is
3112 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3113 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3114 to make it pcrel_offset.
3115 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3116 reloc->address; another gruesome hack to get gas reloc handling to
3119 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3121 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3124 (emit_insn): New function.
3125 (md_assemble): Call it.
3126 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3128 (lituse_pending): New variable. Set by anything that generates a
3129 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3130 tested by code that might want to emit a LITUSE reloc.
3131 (emit_unaligned_io): New function. Currently calls md_assemble,
3132 but it should eventually be converted to generate the insn itself
3133 and call emit_insn directly.
3134 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3135 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3136 emit_bis_r): Likewise.
3137 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3138 (alpha_ip, label get_macro): Don't emit the final instruction if
3140 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3141 unaligned memory access macros.
3142 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3143 the value can't be resolved.
3145 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3147 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3148 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3149 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3151 (mips_force_relocation): New function.
3152 (md_apply_fix): Set fixP->fx_done appropriately.
3153 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

3161 * config/tc-mips.c (enum mips_pic_level): New enum.
3162 (mips_pic): Change from int to enum mips_pic_level. Change all
3163 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3164 (load_address): Handle EMBEDDED_PIC.
3165 (macro): Handle EMBEDDED_PIC in all PIC cases.
3166 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3167 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3168 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3169 works). Do not permit -G with SVR4_PIC.
3170 (s_abicalls): Warn if -G was used, and force -G 0.
3171 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3172 anything but a.out, not just for ELF. For ECOFF, don't generate a
3173 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3175 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3177 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3179 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3180 parameters to avoid losing when compiling with HP CC.
3181 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3183 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3185 * Makefile.in (config-stamp): If `defs' is defined, emit a
3186 preprocessor directive to create a macro named by this value into
3187 config.new; don't explicitly go for BFD_ASSEMBLER.
3188 * configure.in: Define `defs', not `BFDDEF'. Set it to
3189 MANY_SEGMENTS for any obj-coffbfd target.
3190 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3191 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3193 (LOCAL_LOADLIBES): Deleted.
3194 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3195 * config/m88kcoff.mt (TDEFINES): Ditto.
3196 * config/ebmon29k.mt: Deleted.
3197 * config/h8300hds.mt: Deleted.
3198 * config/ic960coff.mt: Deleted.
3199 * config/sparc.mt: Deleted.
3200 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3201 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3202 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3203 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.
3204 (TDEFINES): Don't define the coffbfd macros.
3206 * Makefile.in: Insert makefile fragments before OBJS definition.
3207 (OBJS): Add $(TE_OBJS).
3209 * config/obj-coff.c (obj_pseudo_table): Supply "section"
3212 * write.c (set_symtab): Define only if BFD_ASSEMBLER.
3214 Sun Mar 20 12:06:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3216 * Makefile.in (STAGESTUFF): Add gasp.new.
3218 Fri Mar 18 20:09:16 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3220 * write.c (symbol_table_frozen): New variable, to be set after
3221 bfd_set_symtab is called.
3222 (dump_section_relocs): Note whether a symbol is a section symbol
3224 (adjust_reloc_syms): For now, always supply an absolute symbol for
3225 fixups without symbols but not yet `done'. Use section_symbol to
3226 get the symbol, instead of going directly for abs_symbol.
3227 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3228 reloc is not a section symbol and is not in the symbol table.
3229 (set_symtab): New function, broken out from write_object_file.
3230 Counts symbol table instead of relying on an earlier count.
3231 (write_object_file): Call set_symtab, but do it after potentially
3232 invoking the *_frob_file macros. Don't bother counting symbols.
3233 Call symbol_remove, instead of expanding it in place. Moved the
3234 conditionalized `object_file_size' declaration down to
3235 conditionalized block where it's used. When using the absolute
3236 symbol for a fixup without a symbol, set sy_used_in_reloc.
3237 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3238 the correct symbol for the absolute section.
3240 * subsegs.c (section_symbol): Use symbol_new instead of
3241 symbol_make, since we may want it to go into the symbol table.
3242 Make the new symbol have internal linkage. If
3243 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3244 symbol with the newly created GAS symbol.
3245 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3246 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
3248 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
3250 * config/tc-sparc.c: Include subsegs.h.
3251 (in_signed_range): New function.
3253 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3254 (sparc_ip, label "immediate"): Reject constants for pcrel
3255 instructions only if the relocation type indicates a "call"
3256 instruction and the offset is within range of a "jmpl %g0". If
3257 it's not in range, use the absolute section symbol plus an offset.
3258 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3260 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3262 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3265 * configure.in: Eliminated all targets using obj-coff but not
3266 defining BFD_ASSEMBLER; I think all such targets that are
3267 supported will be matched by real CPU-OS combinations earlier in
3269 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3270 some comments about the dpx2 configuration, but left it disabled,
3271 since it couldn't be reached before.

5118 BFD_RELOC_MIPS_GPREL. Added new case a.
5119 (set_at, load_register, macro): Changed calls to macro_build to
5120 pass new argument for i, j and o cases.
5121 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

5342 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
5343 the table, require that the one without bit 0x1000000 set come

5402 * write.c (write_relocs): For relocs that are pc_relative and
5403 pcrel_offset and not partial_inplace, adjust reloc->addend to

5454 OPTIONAL_REGISTER_PREFIX if either is already defined.
5456 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5458 * configure.in: Set bfd_gas for all sparc targets. Added facility
5459 for keeping or rejecting configurations still under development;
5460 default is to assume production environment, and reject configs
5461 still being worked on. Mark Elf configurations (except sparc and
5462 i386) as developmental. Deleted cases matching some generic names
5463 in favor of more specific names. (E.g., when we get Alpha
5464 support, we'll still only support VMS for Vax.)

5480 through inclusion of tc-hppa.h. Delete all forward declarations
5481 for functions only used within tc-hppa.c, likewise for structures,
5482 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5483 conditional code in a few small places.
5485 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5486 structures, global variables, forward declarations together.
5487 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
5488 conditional code -- try to group conditional code together
5489 into a few places. Make all functions and variables which
5490 are only used within tc-hppa.c static. PARAMize all functions.
5491 Add comments to functions. Delete unused functions, variables,
5492 #defines, etc. Delete unused members within structures. Delete
5493 ldil;ble hacks -- it is believed they were installed to work
5494 around old gas bugs. Avoid using mixed case for local
5495 functions, variables, and structures. Fix formatting problems
5496 not found by GNU-indent. Add FIXME notices for things which
5497 should be worked on the near future. Delete lots of old
5498 useless (1.36 PA-SOM) code.
5500 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
5501 field of the fixS structure. Needed to build unwind
5502 descriptors correctly.

5527 a multiple of the section alignment rather than always a
5530 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5531 bits are zero (eg they specify no relocations), then do not even
5532 bother adding their entries to thesymextn section.

5573 * config/tc-i386.c: (md_begin): Do not zero static arrays. Don't
5574 call strchr for each character to see if it is a special char,

5576 of text, data and bss sections to 4.
5577 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5579 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5580 ELF, since the ELF object format does not have these type of
5581 relocations. Change the abort into as as_bad and return
5582 BFD_RELOC_NONE to silence compiler warnings.
5583 (md_assemble): Keep track of the instruction size. Allow white
5584 space between the $ and the constant for compatibility with older
5585 gases and other assemblers.

6595 are also magic, and have special default flag settings.
6596 (obj_elf_frob_symbol): Since the return value from this function

6660 * Extensive changes to permit symbols to contain any expression
6661 type and to delay the computation of the expression until the
6662 value is actually needed. This permits setting symbols to values
6663 calculated based on object code size. Expressions were changed to
6664 no longer be in a section, to stop the overloading of segment and
6665 expression type that previously occurred.
6667 * as.c (big_section, pass1_section, diff_section, absent_section):
6669 (expr_section): Added (used for dummy symbols which hold

6755 to pop back to it. Handle unquoted section name as well as quoted
6756 section name. Don't crash on invalid strings.
6757 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

7932 references don't appear to work right.
7934 * as.h (const, volatile): Put these definitions back, and use
7937 * doc/as.texinfo: First pass at using new texinfo features --
7938 variables, conditional tests. Far from complete.

7964 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
7965 the bottom (make expands variables in dependencies when the
7966 dependencies are read, not when they are used).
7968 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
7969 a29k .bss section; the mondfe program doesn't like it.

7990 source directory, if that's not the current directory.
7992 * configure.in (per-host): Accept MIPS host with BSD version

8014 process relocs if there aren't any relocs to process. Avoids
8015 malloc/free bug on SCO too.

8018 avoid some redefinition complaints on some systems.
8019 (const, volatile): Don't need these conditionally defined if we
8020 use CONST and VOLATILE from ansidecl.h.
8021 (seg_name): Use CONST, not const.
8023 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
8025 * config/tc-mips.c: Reindented to GNU standards.
8027 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
8029 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
8030 (fixup_segment): Add a29k special case; the linker is not prepared
8031 to see a segment offset here.
8033 * app.c (do_scrub_next_char): Added new state, 10, modifying state

8036 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
8038 * Makefile.in: add dvi target; as-$(config).texinfo might live in
8039 srcdir, might be in objdir.

8059 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
8060 bignums, but don't emit error message.
8062 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
8064 * Makefile.in (targ-cpu.o): Depend on config.h.
8066 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
8068 * app.c (do_scrub_next_char): Added new state, 9, to avoid
8069 dropping a space immediately following an identifier.
8070 * expr.c, write.c: Rewrote assert expressions to not use multiple
8071 lines; I don't think that can be done portably.
8072 * config/tc-mips.c (macro): Use $AT if target register is zero in
8073 load instruction, which it can be for a floating point load.
8075 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

8086 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
8087 z8k-opc.h, not z8k.h.
8089 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
8092 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8094 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
8096 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
8098 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

8147 prototypes for all static functions. Moved existing minimal
8148 debugging format support info #ifndef OBJ_ECOFF blocks.

8197 * make-gas.com: Find obstack.obj if it's not in the current
8199 * read.c (s_ignore): Don't declare is_end_of_line. It's
8200 redundant, and triggers a VMS gcc compiler bug.
8202 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8203 current segment as an argument. (Ignored in all cases but VMS.)
8204 All callers and definitions changed.

8226 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
8228 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8231 * configure.in: mips-bsd configuration was missing format spec.
8234 * Makefile.in (Makefile): Depends on configure.in.
8236 * config/tc-mips.c (append_insn): Don't check for alignment of
8237 frag in memory; alignment of instructions in section is a separate

8257 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8258 constants are accepted, but symbolic values are not. GCC will not
8259 generate the latter currently.
8261 * frags.c (frag_init): New function.
8262 (zero_address_frag, bss_address_frag): Now initialized at run
8264 * as.c (main): Call frag_init.

8308 (fixup_segment): Make sure common-section symbols get treated the
8309 same as undefined symbols.
8310 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type

8340 new section/subsection.
8342 * read.c: Don't include ctype.h.
8343 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
8344 for now; should be machine-dependent.
8346 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
8347 targets, forcing BFD use.

8369 (write_object_file) [! BFD_ASSEMBLER]: Call it.
8370 (relax_and_size_seg) [BFD_ASSEMBLER]: New function; relax section
8371 and set its size and flags.
8373 * struc-symbol.h (struct symbol) [BFD_ASSEMBLER]: Replace some

8515 md_relax_table): Use default zero initialization.
8516 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
8517 latter, instead of selecting with preprocessor conditionals.
8519 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8521 * configure.in: recognise all sparclite variants

8531 * expr.c (operand): If character other than comma or newline is a
8532 logical end-of-line character, use the newline case.
8533 From Eric Youngdale:
8534 (operand): Set X_add_number field for floating-point numbers.
8535 (operand): Treat zero byte as end-of-operand.
8537 * configure.in (per-target): Look for with_bfd_assembler option.
8538 For now, only accept "no", until the merge is done.
8540 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8541 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8542 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8543 * read.c: Finish conversion to S_* macros in the VMS only
8544 parts of the program. Add "const" modifier to hex_value.
8545 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
8547 * expr.c: Add "const" modifier to hex_value.
8548 * symbols.c: Finish conversion to S_* macros in the VMS only
8549 parts of the program. Add "const" modifier to
8550 md_[long,short]_jump_size. Remove declaration of const_flag
8551 (which will be declared in obj-vms.h).
8552 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8553 Fix arguments to VMS_write_object_file.
8554 * config-gas.com: New file. Script for VMS systems to set up the
8555 configuration to build gas for VMS, and create config.status.
8556 * make-gas.com: Redone to work with new scheme.
8557 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8559 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8560 will swap bytes if needed on a big endian system. Use throughout
8562 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8563 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8564 types of malformed stabs. Change parsing algorithm so that we are
8565 more certain of having all of the information that we need on hand.
8566 * obj-vms.c (final_forward_reference): New function, used to help
8567 resolve the data types of as many struct elements as possible
8568 when some part of the struct is not fully defined by the compiler.

8571 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8572 as symbols as well in the object file. Look for external functions
8573 that start with "__vt.", and turn them into variables, since the
8574 g++ compiler is incapable of doing this.
8575 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8577 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8578 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8579 have the name of the source file yet.
8580 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8582 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8584 * read.c (s_data): Always use "data_section", since it'll map to
8585 SEG_DATA or SEG_E1 if needed.
8586 (s_lcomm): Likewise with bss_section.
8587 (s_fill): Use memset, not bzero.
8589 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8611 (big_section, reg_section, pass1_section, diff_section,
8612 absent_section, text_section, data_section, bss_section): If
8613 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8614 mapping to segT enum values.
8615 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8616 if these are used or defined, if BFD_ASSEMBLER.
8617 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8618 subseg_new split into two functions.
8619 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8621 * as.h (volatile): Don't define if already defined.
8622 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8624 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8625 declare with format attribute for -Wformat checking.
8627 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8629 * app.c, config/tc-*.c: Don't include read.h, since it is already
8632 * These are based on patches from Minh Tran-le
8633 <mtranle@paris.intellicorp.com>.
8634 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8635 obj_format coffbfd and gas_target i386coff for target.
8636 (i[34]86-*-isc*): New host (uses sysv).
8637 * config/i386aix.mt: Removed (no longer used).
8638 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8640 (LDFLAGS): Added, defined as -shlib.
8641 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8642 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8643 (DOT_LABEL_PREFIX): Define.
8644 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8645 name rather than L0\001.

8657 (size_section): Restored sanity check.
8658 (do_relocs_for): Base section address on s_paddr rather than
8659 computing it. Adjust a29k R_IHIHALF special case to account for
8660 section paddr (used to require paddr to be zero). If there are no
8661 reclos, set s_relptr to 0. Set relocation size in object_headers.
8662 (fill_section): Always set s_vaddr here, removing
8663 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8664 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8665 Set STYP_INFO for .comment.

8669 H_{SET,GET}_* macros.
8670 (do_linenos_for): Set lineno size in object_headers.
8671 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8672 set s_vaddr here. If string_byte_count remains 4, set it back to
8673 0, and only write strings out if there are some. Call
8674 fill_section before do_relocs_for and do_linenos_for.
8675 (obj_coff_section): Handle optional quoted second argument giving
8676 section characteristics.
8677 (obj_coff_bss): Added to handle .bss.
8678 (obj_coff_ident): Added to handle .ident (puts string in .comment

8698 (do_scrub_next_char): For \", return " not '.
8699 (symbol_chars): Now const.
8701 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8702 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8704 * config/obj-coff.h: Don't use #elif.
8706 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8707 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
8709 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
8711 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

8733 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8734 using ZERO_BASED_SEGMENTS.
8735 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8736 never set segment address for SEG_E2 (.bss) and don't write out
8737 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8738 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8739 definitions, and don't merge tags with non-tags. Check for .bf
8740 rather than just checking whether the second character is b and
8741 the third character is f.
8742 (obj_coff_val): gcc can generate values which we don't handle
8743 correctly; discard information for now, since it only affects the
8744 debugging information.
8745 (tag_find_or_name): Don't insert tags in the symbol table.
8746 (yank_symbols): Don't merge labels.
8747 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8885 * all files: Whitespace changes for GNU indentation style, done by
8886 GNU `indent'. Some cleanup still needed, especially of comments.
8888 * configure.in: No te-386bsd.h file exists; don't try to use it.
8890 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
8892 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
8893 could be doing emulation.
8895 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8898 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

8916 putting them in the symbol table.
8917 * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not

8923 * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
8924 comment_chars, line_comment_chars and line_seperator_chars
8925 consistently const, and always initialized them. Included read.h.
8927 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8929 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8930 constant will not fit in an immediate field.
8931 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
8933 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
8935 * obj-coff.c (callj_table): Delete global variable.
8936 (obj_emit_relocations): Define it locally here, and only if

8942 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
8943 with a single set using PARAMS macro.
8945 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length

8950 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
8951 so widening works consistently.
8953 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
8955 * version.c: Put conditional "const" before version_string, not
8956 before dummy function for VMS. Now version 1.91.03.
8958 * app.c (do_scrub_next_char): Need double-\ before `000' to show
8959 printed rep of null character.
8961 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
8963 * obj-coffbfd.c (write_object_file): check return value of
8966 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8968 * Support for i386-sysv.
8969 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
8970 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
8971 be used to set them all to zero as was done before.
8972 (fill_section): segment addresses now set in write_object_file.
8973 (fill_section): Don't set STYP_NOLOAD for .bss section.
8974 (fixup_segment): 386 uses strange common symbol format.
8975 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
8976 compatibility with SVR3.2 linker.
8977 * configure.in: i386-sysv and i386-sco use coffbfd.
8979 * app.c (do_scrub_next_char): discard whitespace after a label.

8988 fix i960+non-bfd coff bit rot.
8989 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
8990 support for C source listings. (obj_coff_endef): look in the right
8991 part of the symbol for the symbol name
8993 * tc-m68k.c (get_num): make it work for all segments, not just the
8996 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8998 * configure.in: recognize i386-*-bsd emulation.

9007 * tc-z8k.c: lots of bug fixes
9009 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
9011 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
9012 #elif, since it is not supported by old compilers.
9013 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
9014 couple of expressions in tc-m68k.c.
9016 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9018 * read.c (cons): If NO_RELOC is defined, use it.
9020 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
9022 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
9024 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
9025 local labels to start with a .) and set REGISTER_PREFIX to %.
9026 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
9028 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

9039 * listing.c (debugging_pseudo): Add stabs and stabn as things to
9042 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
9044 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9045 sections starting from zero, rather than making them consecutive.
9046 This makes subsequent reloc calculations easier, esp if the object
9047 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9048 allocate lcomm in .data rather than in .bss. It seems that some
9049 tools can't cope with a non-zero sized bss before linkage.
9051 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9053 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
9054 throughout. That enum no longer means what we thought it meant.

9057 "-mno-688[58]1" options.
9059 * tc-m68k.c: Added CPU32 support.

9068 Change LIBDEPS dependence to LIBS.
9070 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
9072 * Makefile.in (install): if $(tooldir) exists, install as in
9075 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
9077 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9078 .word is < -32768 or > 32767. The -J flag causes the error to be
9079 ignored. This is to catch over-sized switches generated by gcc on
9080 systems which don't support the broken .word hack.
9081 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9082 write.c (fixup_segment): check for signed .word overflow if
9083 WARN_SIGNED_OVERFLOW_WORD.
9085 * write.c (fixup_segment): fixed missing parens in expression
9086 checking for byte or word overflow.
9088 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
9089 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
9090 WARN_SIGNED_OVERFLOW_WORD.

9098 * obj-coffbfd.h : added stuff
9099 * tc-i386.c (tc_coff_fix2rtype): new function
9100 * tc-i386.h : new coff defines
9102 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
9104 * input-scrub.c (input_scrub_push): call input_file_begin, not
9106 messages.c (as_perror): print ": " between the passed in error and
9107 the strerror, like perror does.
9109 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
9111 * Makefile.in: use gas_target instead of modifying target_cpu.
9112 From Steve Chamberlain:
9113 Makefile.in: Handle m68*-*-coff*.
9114 read.c, read.h: add mult argument to s_space
9116 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
9117 Motorola and MIT syntax; gas can now assemble either type of
9119 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
9120 From Steve Chamberlain:
9121 m68kcoff.mt: for m68k COFF.
9122 obj-coffbfd.c: (fixup_mdeps) added
9123 (size_section) removed bad sanity check

9125 (write_object_file) call fixup_mdeps
9126 (fixup_segment) set fx_subsy to 0.
9127 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9129 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9132 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9134 * Makefile.in (LIBS): Include opcode library.
9136 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
9138 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers

9156 tc-i960.c (md_ri_to_chars): Always output bout object file in
9157 little endian byte order (used to use endianness of host).
9159 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9161 * config/tc-m68k.c (init_table): Now const. Always include 68851
9162 data, so that "bc" is available to 68040 cache instructions.
9163 Added "tt0", "tt1", and 68ec030 variants.
9164 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9165 (enum _register): Added TT0, TT1.
9166 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9167 line number correctly in "internal error" messages. Don't print
9168 architecture-mismatch message for operand errors.
9170 From Colin Smith (colin@wrs.com):
9171 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
9172 than install_operand.

9176 * listing.c (buffer_line): rewind to the start of include
9177 files, they might be included twice.

9184 one element of a family.
9186 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
9188 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
9189 so that we can assemble hand-written libgcc code.
9191 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9193 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9194 has already been formatted (but may still contain %-characters).
9197 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9199 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9200 written with indirection on the last two operands, which can be
9201 either data or address registers. Added a new operand type 'r'
9202 which accepts either register type. Added '(' to notend stuff in
9203 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
9205 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

9218 defined, call it. Change segments before calling fixup_segment.
9219 (relax_align): If linkrelax, provide extra padding.
9221 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
9222 their not having symbols associated.
9224 * tc-i960.c (norelax, instrument_branches): Default initializer is
9226 (linkrelax): Delete variable definition.

9249 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
9250 being used with args swapped, causing occasional lossage when
9251 refilling buffers after an include file.
9253 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
9255 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
9256 version. Discard bogus DONTDEF version.
9257 (as_warn, as_bad, as_fatal): Likewise.

9261 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
9262 selected architecture, print a message saying so and listing what

9284 * read.c (s_fill): make the .fill size clamped error a warn and
9285 fix bug where 0's were always placed.
9287 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
9288 two bytes of any constant with 0xff:

9307 * configure.in (mips host): Accept "ultrix" with version number.
9309 * expr.c (floating_constant): Separate "=-" to avoid confusing
9310 ancient or broken compilers.
9312 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
9313 processor/opcode mismatch, so reword the error message.
9314 (md_assemble): If no CPU has been set (even if FPU/PMMU
9315 characteristics have been), default to 68020. Don't need extra
9316 quotes around error string.
9318 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
9320 * read.c (potable): Revert sac's incorrect change made Jul 13.

9390 * write.c (write_object_file): If a.out don't use the old way for
9392 * config/obj-a.out (s_sect): complain if the user tries to use a
9393 subsegment with a value which might interfere with out -R hackery.
9394 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
9395 rather than use ugly if tree. (init_regtable): insert register
9396 names into symbol table.
9398 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
9400 * write.c (write_object_file): keep the fix_tail clean, which
9401 fixes a bug in -R where relocations were being lost.
9403 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
9405 * configure.in: recognize m680x0 as having sun3 emulation mode for

9428 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9430 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
9431 calc the base of relocs correctly.
9432 * tc-a29k.c (parse_operand): allow expressions to be in any section.
9434 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
9436 * as.c, write.c: use -K rather than -k for the broken word warning

9449 * write.c (write_object_file): For b.out format, round up section
9450 start addresses to match required alignment.
9452 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9454 * Makefile.in (install): Install into $(tooldir)/bin, since that's
9455 where gcc looks for it.
9457 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
9459 * Makefile.in: Changed some lines to be less confusing for some
9462 * input-file.c: Conditionalize on _IOFBF, not VMS.
9464 * read.c, write.c: Change a series of ifdef/elif to

9525 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9527 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9529 * expr.c (operand): if can't work out what sort of operand it is,
9530 then look through FLT_CHARS for a hint.
9532 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9534 * Makefile.in, configure.in: removed traces of namesubdir,
9535 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9536 copyrights to '92, changed some from Cygnus to FSF.
9538 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9539 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9540 copyrights to '92, changed some from Cygnus to FSF.
9542 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9544 * expr.c: If an expression is single comma, then return with
9545 SEG_ABSENT rather than an error - since the sparc front end does
9546 really strange things with things like fbge,a
9548 * as.h: include bfd.h if using many sections
9549 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9550 local labels didn't work.
9551 * listing.c (list_symbol_table): don't core dump when there's no
9553 * write.c, write.h: call fix_new with the right number of args on
9555 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9558 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9560 * app.c: MRI compatibility - allow single quote to start a string.
9561 * as.c: fix typo recently introduced.
9562 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9563 * expr.c: Much rewriting, to accomodate MRI syntax for
9564 expressions. Also easier to read now.
9565 * listing.c: Put back defuns
9566 * read.c: modified to accept MRI syntax, put back listing pseudo
9567 ops so that an assembler built with NO_LISTING ignores list ops
9569 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9570 machine is a SPARC or a 29K.
9571 * config/obj-aout.c: added s_sect pseudo op
9572 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9573 fill in the timestamp.
9574 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9575 anymore, define all the relocs which the tc-<x> bit will use so we
9576 can translate from them to the coff types.
9577 * config/tc-a29k.c: reloc_type isn't ane enum any more
9578 * config/tc-m68k.c: Added NO_RELOC definition.
9580 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9582 * Makefile.in: put header files before C source for TAGS; remove
9583 references to non-existent syscalls.h.
9585 * read.c, write.c subsegs.c: back out the .bss changes.
9587 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9589 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9593 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9595 * symbols.c (local_label_name): symbols now start with ^A.
9597 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9598 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9599 generate these sections. .align: will use NOP_OPCODE or 0
9600 for padding. This is just for being nice to the
9603 * expr.c (operand): changed to generate local label "\001L0"
9604 starting with a ^A so that it is recognized as a local label.
9606 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9608 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9609 i/o opcodes - inb, inw, outb and outw. string manipulation with
9610 att syntax - scmp, slod, smov, ssca, ssto.
9612 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9613 to just after .file .
9615 In obj_crawl_symbol_chain() where it tries to put the external
9616 symbols apart, with the condition:
9617 (!S_IS_DEFINED(symbolP) &&
9618 !S_IS_DEBUG(symbolP) &&
9619 !SF_GET_STATICS(symbolP))
9620 it was moving too many symbols out. So I switch it back to the
9622 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9624 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9625 so that we don't use the F_RELFLG which make the linker complain
9626 that somebody has stripped the relocation info.
9628 Also, the AIX ld program require that the relocation table
9629 is sorted by r_vaddr like the standard ATT assembler does.
9631 [he also changed the sizeof(struct ...)'s into the coff
9632 style FOOSZ macros. I'm not sure this is right, but I can't
9633 remember why. xoxorich.]
9635 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9637 * Makefile.in, configure.in, doc: use the doc. Build it, install
9640 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9642 * read.c: white space and comments only.
9644 * configure.in: use the new atof-ns32.c for ns32k.
9646 * write.c: comment change only.
9648 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9649 aren't yet integrated.
9651 * tc-i860.[hc]: blew off the dust. Something must still be done
9652 about conflicting relocation types.
9654 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9657 * tc-i960.c, tc-sparc.c: white space and comments only.
9659 * tc-a29k.h: delete duplicate macro definition.
9661 * new file atof-ns32k.c copied from hack's last unreleased gas.
9663 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9665 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9668 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9669 ChangeLog's prior to this are sketchy at best. I have logs.
9670 They just aren't ChangeLogs.
9677 version-control: never
