992 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
993 (tc_gen_reloc): Simplify. It's no longer necessary to set a
994 reloc's addend field to zero for function symbols.
995 (md_apply_fix): Simplify. For fixups which will require a SOM
996 reloc, just clear out the necessary bits in the output file.
998 Fri Oct 14 19:06:46 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1000 * Makefile.in (BISON): Use bison -y, not bison.

1014 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1016 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
1017 it's better to use the one in libiberty.
1019 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1021 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
1022 change; it breaks the rs6000 support, and doesn't seem to be
1025 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1027 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

1033 rather than explicitly adding the frag address.
1034 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
1035 the end of the line numbers; this replaces the zero entry which
1036 used to be added by coff_add_linesym, removed Oct 7.
1037 (coff_adjust_section_syms): Ignore sections with no seginfo.
1039 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1041 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a
1042 "stage" symlink to the appropriate stage* directory, and use it
1043 instead in the -B options.
1044 (comparison): Revert yesterday's change.
1046 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1048 * config/tc-sparc.c (tc_gen_reloc): For non-a.out relocations, if

1051 Tue Oct 11 15:24:00 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
1053 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
1054 for an embedded PIC switch expression, since the definition of
1055 S_IS_LOCAL was changed.
1057 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1059 * Makefile.in (comparison): When comparing as.new or gasp.new, try
1060 running the binary through sed to avoid differences due to
1061 "stage1" or "stage2" having been written into the binary.
1063 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1065 ELF symbol size handling, based on code from Eric Youngdale:
1066 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an

1073 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
1075 (obj_elf_size): Deleted unused code. If size is non-reducible
1076 expression, allocate some storage for the sy_obj field and copy
1078 (elf_frob_symbol): New function. Computes sizes, calls
1079 ecoff_frob_symbol if appropriate.
1081 * write.c (fixup_segment): For i386 elf and coff (for now), don't
1082 add in value of symbol from another defined section of the file.
1084 Fri Oct 7 17:54:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

1128 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
1130 (diststuff): New target; builds DISTSTUFF.
1131 (realclean): Separate target, depend on clean and distclean, then
1133 * make-gas.com: Deleted.
1135 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
1136 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
1138 (i386_operand): Don't look up section symbol for
1140 (reloc): Always permit return of 8- and 16-bit relocation types.
1141 Add a space after "pc-relative" in the error message.
1142 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1143 BFD_RELOC_386_GOTOFF relocs.

1147 (TC_VALIDATE_FIX): New macro -- call it.
1148 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.
1150 * as.h: If __STDC__ is not defined and varargs.h is available, use
1151 it rather than stdarg.h.
1153 * write.h (struct fix): Added new bitfield fx_plt, for fixups
1154 referring to PLT entries.
1155 * write.c (fix_new_internal): Initialize fx_plt to zero.
1156 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
1157 Don't adjust fx_offset by frag address, since S_GET_VALUE now
1158 includes the frag address.
1159 (fixup_segment): Changed local var PCREL to type int, added PLT.
1160 If PC-relative fixup refers to a PLT entry for a symbol in the
1161 current section, don't reduce it.

1167 and after processing.
1168 (print_fixup): Added prototype. Show address on first line. Show
1169 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

1183 Show fx_r_type and fx_addsy fields.
1185 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1187 * configure.in: Set bfd_gas for all sparc targets in one place,
1188 instead of separately for each. Correctly handle user-supplied
1189 "--enable-bfd-gas" option.
1191 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1193 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
1196 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
1197 processing if add_symbol is undefined or in expr_section.

1199 constant-valued symbol, convert to O_symbol and re-reduce.
1200 (S_GET_VALUE): If symbol needs resolving, resolve it.
1201 (indent_level): No longer static.
1202 (print_symbol_value_1): Don't print frag address if it matches

1206 (print_expr_1): Fix whitespace before printing X_add_number.
1208 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1209 not symbol_new, for symbols holding expression values.
1210 * expr.h (make_expr_symbol): Move declaration here.
1211 * write.c (fix_new_exp): Handle O_add by creating an
1212 expression-valued symbol, and calling fix_new_exp recursively.
1213 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1214 undefined symbol and a constant, fold the constant into the fixup,
1215 and refer to the undefined symbol directly. Then process the
1216 fixup again from scratch.
1217 (write_object_file): Before calling adjust_reloc_syms, make a pass
1218 through the symbol list trying to resolve values.
1220 * write.c (print_fixup): New routine, for debugging.
1221 (write_relocs): Call bfd_install_relocation. Deleted various
1222 hacks for working around problems with bfd_perform_relocation.
1224 * Makefile.in (VERSION): Update to 2.4.90.
1226 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1228 * Makefile.in (gasp.o): Depends upon config.h.
1230 * config/tc-mips.c: Include subsegs.h.
1231 (md_apply_fix): If an unconditional b or bal overflows, and we are
1232 not assembling PIC code, replace it with a j or jal.
1234 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1235 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
1237 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1239 * write.c (write_relocs): Add file name and line number to
1240 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1241 RELOC_EXPANSION_POSSIBLE.
1243 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1245 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1246 here. Use them for deciding which PRINTF*LIKE macro definitions
1248 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1249 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1250 default definitions matching what we were doing before.
1251 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1252 always use the varargs form if not using stdarg. It's safe to
1253 always use vfprintf, because libiberty will provide it if the
1254 native system doesn't. Also, always make format be const.
1255 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
1257 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1270 (listing_newline): Check filename as well as line number when
1271 deciding whether to record it.
1272 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1273 false (if defined) as well as checking for reg_section.
1274 (listing_listing): Iterate fetching lines while line number is too
1275 low, and we haven't run off the end of the input file.
1277 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1279 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1281 * ecoff.c (ecoff_generate_asm_lineno): check if
1282 current_stabs_filename is NULL before strcmp.
1283 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
1286 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1288 * config/ho-*.h: Now-unused files deleted.
1290 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1291 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1292 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1293 zero. Don't call obj_frob_forward_symbol.
1294 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1295 X_add_number is zero.
1296 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1298 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1300 (strchr): Don't declare.
1301 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
1302 md_estimate_size_before_relax, md_ri_to_chars,
1303 md_create_short_jump, md_create_long_jump.
1304 (brtab_emit): Use data_section, not SEG_DATA.
1306 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1308 * config/vms-conf.h: new file, manually derived from conf.in.
1309 * config-gas.com: use it, and eliminate obsolete "host.h".
1311 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1313 * config/tc-ppc.c (ppc_current_block): New static variable.
1314 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
1315 ppc_current_block. Don't move around any stab symbol, just those
1317 (ppc_bs): Set ppc_current_block.
1318 (ppc_es): Clear ppc_current_block.
1319 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1320 from the csect of the enclosing block.
1322 * config/tc-mips.c (insns_since_cache_access): Remove.
1323 (append_insn): Remove setting of insns_since_cache_access, and
1324 special 4600 handling; it turns out not to be required.
1326 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1328 * config/tc-mips.c (md_shortopts): Remove E.
1329 (md_longopts): Add EB and EL.
1330 (md_parse_option): Handle -EB and -EL as separate options, rather
1331 than as a single -E option with an argument.
1333 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
1335 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
1336 involving global symbols too.
1338 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1340 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1342 * configure.in: Test for remove, not delete. Fix cross-assembler
1344 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1347 * read.c (pseudo_set, case O_symbol): If
1348 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1349 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1350 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1352 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1354 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1355 many others): new macros; values obtained from "DSTRECRDS.SDL".
1356 * config/obj-vms.h (various): use them.
1357 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1358 representation (only enum bitfields can avoid being bitstrings).
1359 (bitfield_suffix, setup_basic_type): new routines.
1360 (VMS_typedef_parse): use them. Now recognize bitfields of all
1361 integral types, not just type `int'. Caveat: the representation
1362 used for bitfields still does not work for objects placed in
1363 registers, and gcc's optimizer sometimes puts small structs there.
1365 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1367 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1368 bit from const_flag.
1369 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1370 (tc_frob_label): define this to call vms_check_for_special_label,
1371 and declare the latter.
1372 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1374 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1375 (vms_check_for_special_label): new routine (tc_frob_label).
1376 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1377 and `gcc2_compiled.' labels; they won't reach here any more.
1378 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1379 double', use `vax_g_doubles' flag to select type of double.
1380 (VMS_write_object_file) [traceback setup]: don't pass symbols
1381 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1382 and TBT_Routine_End functions.
1384 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
1386 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1387 S_GET_VALUE() to avoid many repeated function calls.
1388 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1389 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1390 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1391 be obsolete; gcc does it automatically for vms target. It's
1392 also misnamed, because it is for the "VAX C" run-time library,
1393 not the newer "DEC C" one which has much different startup code.]
1394 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1395 `S_GET_xxx(symbol) = new_value'.
1397 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1399 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1400 not &bfd_abs_section.
1402 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1404 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1406 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1408 * expr.c (expr): Don't reduce the difference of two symbols in the
1409 same frag if the symbols are not in normal sections.
1411 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1412 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1413 (obj_attach_unwind_info): Do not define. Not needed anymore.
1414 * config/tc-hppa.c: Delete whitespace at EOL.
1415 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1416 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1417 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1418 fixups, store 32bits of unwind information in the fx_addnumber
1420 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1421 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1422 pointer to 32 bits of unwind info.
1423 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1424 pointer to the dummy symbol; set the addend field to fx_addnumber.
1425 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1426 rather than &bfd_XXX_section.
1428 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1430 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1431 value by one; discard adjustments previously being made. From
1434 VMS- and Vax-related changes from Pat Rankin:

2380 (DBG_S_C_REAL8_G, DBG_S_C_COMPLX8_G): G_float versions of
2381 REAL8 and COMPLX8; not used yet, because gcc outputs the same
2382 .stabs for `double' regardless of whether `-mg' is used.
2383 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
2384 for gcc2's predefined types "complex float", "complex double",

2394 $8,%hi(foo); lw $8,%lo(foo)($8)'' work correctly.
2396 Mon Jun 13 12:08:52 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2398 * config/obj-aout.c (obj_aout_frob_symbol): Warn about an attempt
2399 to put a common symbol in a set.

2405 OBJ_BOUT if not BFD_ASSEMBLER.
2406 * config/aout_gnu.h (N_WEAKU, N_WEAKA, N_WEAKT, N_WEAKD, N_WEAKB):
2407 Define as in ../include/aout/aout64.h.

2423 Wed Jun 8 06:28:37 1994 Bill Cox (bill@cygnus.com)
2425 * Makefile.in (check): Delete as.new dependency, so that

2442 Fri Jun 3 23:35:36 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2444 * read.c (emit_expr): Use memset to zero out memory, rather than
2445 going through md_number_to_chars. This permits handling symbolic

2498 m68040_control_regs, m68060_control_regs): New arrays.
2499 (control_regs): New pointer.
2500 (m68k_ip): Use control_regs instead of testing CPU every time.
2501 Use last_movec_reg too. In error messages, handle 68060, and
2502 print 68060 for mfloat, too.
2503 (m68k_init_after_args): Handle "68060". Use m68040up for making
2504 m68851 choice. Set control_regs.

2827 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
2829 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
2830 can be used within a label name.
2832 * config/tc-m68k.h (m68k_init_after_args): Declare.
2833 (tc_init_after_args): Define as m68k_init_after_args.
2834 * config/tc-m68k.c (m68k_init_after_args): New function,
2835 containing one-shot code from md_assemble. Added warning for
2836 combination of 68040 and 68851.
2837 (md_assemble): Startup-time code deleted.
2839 Mon Apr 25 16:19:17 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2841 * doc/Makefile.in (clean, distclean): Remove asconfig.texi.

2850 * config/obj-ecoff.c (ecoff_frob_file): Use bfd_ecoff_set_gp_value
2851 and bfd_ecoff_set_regmasks to set the GP value and the register
2852 masks, rather than using the now obsolete fake .reginfo section.
2854 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2856 * listing.c (list_symbol_table): Don't print register symbols as
2859 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
2860 underscores, since symbol_new will already have done it.
2861 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
2863 * as.c (main): If tc_init_after_args is defined, invoke it after
2864 all arguments have been processed.
2866 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
2867 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
2868 section instead of .text. Call create_target_segments.

2873 * config/tc-mips.c (append_insn): Permit branches to be switched
2874 with the preceding instruction even if .set nobopt has been seen.
2875 .set nobopt actually controls whether to bring up an instruction
2876 from the branch target, which gas does not currently support.
2878 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2880 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

2894 multiple of alignment power specified in bfd target vector.
2896 * gasp.c: Include ctype.h.

2917 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
2918 defaults for defined, private, and spnum fields for the

2929 address zero, insert a dummy line to compensate.
2931 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
2934 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2936 * expr.c (operand): Try to parse "0f" and "0b" sequences as
2937 floating point and binary numbers respectively; if it doesn't
2938 work, treat them as local labels.
2940 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
2941 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2943 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2945 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2946 source files from other directories into objects in the current
2947 directory, and specify PSECT attributes explicitly to linker.
2948 Also added missing label.
2949 * Makefile.in (stamp-mk.com): Reference new variable
2950 VMS_OTHER_OBJS for list of non-local object files, instead of

2965 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
2966 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
2967 argument, the reloc type.
2968 (load_register): Pass reloc type to macro_build for 'u'.
2969 (macro): Likewise. For M_LA_AB permit a difference expression
2970 when generating embedded PIC code between an arbitrary symbol and
2971 a symbol in the .text section.
2972 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2973 BFD_RELOC_PCREL_LO16 to be emitted.

2981 * subsegs.c (subsegs_begin): Call memset with args in the correct
2983 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2984 to NULL instead of 0.

2988 * config/tc-hppa.c (pa_procend): Handle case where label was
2989 defined after the .proc directive.

3013 (hppa_tc_symbol): Likewise.
3015 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
3016 elf_tc_make_sections stuff. It was there to support PA braindamage
3017 which has been fixed, and in the case of elf_tc_make_sections is
3018 redundant with elf_tc_final_processing.
3020 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3022 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

3032 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
3033 value into the file if the fixup will not generate a reloc.
3035 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
3037 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
3038 don't spew remainder of input file in error message.
3039 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3040 message with reloc type and try to process remainder of file.
3042 * doc/Makefile.in (install-info-as, install-info-gasp): New
3043 targets, now explicitly checking $(srcdir) for info files.
3044 (install-info): Depend on both of them; do nothing more.

3048 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
3050 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3052 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
3053 flag rather than signedp field. Only permit extended range if
3054 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
3055 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
3057 * config/tc-ppc.c (ppc_size): New static variable.
3058 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
3059 (md_begin): If an instruction has a size specific flag set, only
3060 add it if we are assembling that size.
3062 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3064 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3065 cross section PC relative relocs right for COFF and ELF.
3067 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3069 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
3070 (OBJ_PROCESS_STAB): Don't define.
3072 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3074 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3075 the type of symbol set symbols which happen to be in the absolute
3076 or undefined section.
3078 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
3080 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3081 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3082 and -many (all architectures).
3084 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3086 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
3087 involving a function symbol which is not a plabel to zero.
3088 (md_apply_fix): Never pass a function symbol to field_adjust.
3090 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3092 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3093 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3095 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3096 branch with an instruction that uses $at, in case the branch is
3098 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3099 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3100 to make it pcrel_offset.
3101 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3102 reloc->address; another gruesome hack to get gas reloc handling to
3105 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3107 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3110 (emit_insn): New function.
3111 (md_assemble): Call it.
3112 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3114 (lituse_pending): New variable. Set by anything that generates a
3115 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3116 tested by code that might want to emit a LITUSE reloc.
3117 (emit_unaligned_io): New function. Currently calls md_assemble,
3118 but it should eventually be converted to generate the insn itself
3119 and call emit_insn directly.
3120 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3121 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3122 emit_bis_r): Likewise.
3123 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3124 (alpha_ip, label get_macro): Don't emit the final instruction if
3126 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3127 unaligned memory access macros.
3128 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3129 the value can't be resolved.
3131 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3133 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3134 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3135 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3137 (mips_force_relocation): New function.
3138 (md_apply_fix): Set fixP->fx_done appropriately.
3139 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

3147 * config/tc-mips.c (enum mips_pic_level): New enum.
3148 (mips_pic): Change from int to enum mips_pic_level. Change all
3149 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3150 (load_address): Handle EMBEDDED_PIC.
3151 (macro): Handle EMBEDDED_PIC in all PIC cases.
3152 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3153 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3154 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3155 works). Do not permit -G with SVR4_PIC.
3156 (s_abicalls): Warn if -G was used, and force -G 0.
3157 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3158 anything but a.out, not just for ELF. For ECOFF, don't generate a
3159 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3161 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3163 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3165 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3166 parameters to avoid losing when compiling with HP CC.
3167 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3169 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3171 * Makefile.in (config-stamp): If `defs' is defined, emit a
3172 preprocessor directive to create a macro named by this value into
3173 config.new; don't explicitly go for BFD_ASSEMBLER.
3174 * configure.in: Define `defs', not `BFDDEF'. Set it to
3175 MANY_SEGMENTS for any obj-coffbfd target.
3176 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3177 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3179 (LOCAL_LOADLIBES): Deleted.
3180 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3181 * config/m88kcoff.mt (TDEFINES): Ditto.
3182 * config/ebmon29k.mt: Deleted.
3183 * config/h8300hds.mt: Deleted.
3184 * config/ic960coff.mt: Deleted.
3185 * config/sparc.mt: Deleted.
3186 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3187 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3188 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3189 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

3206 * write.c (symbol_table_frozen): New variable, to be set after
3207 bfd_set_symtab is called.
3208 (dump_section_relocs): Note whether a symbol is a section symbol
3210 (adjust_reloc_syms): For now, always supply an absolute symbol for
3211 fixups without symbols but not yet `done'. Use section_symbol to
3212 get the symbol, instead of going directly for abs_symbol.
3213 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3214 reloc is not a section symbol and is not in the symbol table.
3215 (set_symtab): New function, broken out from write_object_file.
3216 Counts symbol table instead of relying on an earlier count.
3217 (write_object_file): Call set_symtab, but do it after potentially
3218 invoking the *_frob_file macros. Don't bother counting symbols.
3219 Call symbol_remove, instead of expanding it in place. Moved the
3220 conditionalized `object_file_size' declaration down to
3221 conditionalized block where it's used. When using the absolute
3222 symbol for a fixup without a symbol, set sy_used_in_reloc.
3223 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3224 the correct symbol for the absolute section.
3226 * subsegs.c (section_symbol): Use symbol_new instead of
3227 symbol_make, since we may want it to go into the symbol table.
3228 Make the new symbol have internal linkage. If
3229 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3230 symbol with the newly created GAS symbol.
3231 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3232 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
3234 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
3236 * config/tc-sparc.c: Include subsegs.h.
3237 (in_signed_range): New function.
3239 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3240 (sparc_ip, label "immediate"): Reject constants for pcrel
3241 instructions only if the relocation type indicates a "call"
3242 instruction and the offset is within range of a "jmpl %g0". If
3243 it's not in range, use the absolute section symbol plus an offset.
3244 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3246 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3248 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3251 * configure.in: Eliminated all targets using obj-coff but not
3252 defining BFD_ASSEMBLER; I think all such targets that are
3253 supported will be matched by real CPU-OS combinations earlier in
3255 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3256 some comments about the dpx2 configuration, but left it disabled,
3257 since it couldn't be reached before.
3258 (target a29k-amd-ebmonold): Deleted.
3260 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3262 * config/tc-hppa.c (pa_import): Correctly handle importing of an
3263 already defined symbol.
3265 Wed Mar 16 17:11:37 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3267 * config/tc-mips.c (mips_ip): Only accept overly large values for
3268 the 'j' operand if there are no further alternatives for this
3271 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3272 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3273 is not SEG_UNKNOWN rather than checking whether it is >= 0.

5037 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
5038 standard hpux include files to pick up various function decls.
5040 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

5073 of interest to the linker. ENTRY/EXIT relocations for SOM are
5074 an example of marker relocations.

5103 assuming BFD_RELOC_LO16. Don't try to convert BFD_RELOC_LO16 to
5104 BFD_RELOC_MIPS_GPREL. Added new case a.
5105 (set_at, load_register, macro): Changed calls to macro_build to
5106 pass new argument for i, j and o cases.
5107 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
5108 special handling when generating SVR4 PIC code.

5440 OPTIONAL_REGISTER_PREFIX if either is already defined.
5442 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5444 * configure.in: Set bfd_gas for all sparc targets. Added facility
5445 for keeping or rejecting configurations still under development;
5446 default is to assume production environment, and reject configs
5447 still being worked on. Mark Elf configurations (except sparc and
5448 i386) as developmental. Deleted cases matching some generic names
5449 in favor of more specific names. (E.g., when we get Alpha

5466 through inclusion of tc-hppa.h. Delete all forward declarations
5467 for functions only used within tc-hppa.c, likewise for structures,
5468 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5469 conditional code in a few small places.
5471 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5472 structures, global variables, forward declarations together.

5474 conditional code -- try to group conditional code together
5475 into a few places. Make all functions and variables which
5476 are only used within tc-hppa.c static. PARAMize all functions.
5477 Add comments to functions. Delete unused functions, variables,
5478 #defines, etc. Delete unused members within structures. Delete
5479 ldil;ble hacks -- it is believed they were installed to work
5480 around old gas bugs. Avoid using mixed case for local
5481 functions, variables, and structures. Fix formatting problems
5482 not found by GNU-indent. Add FIXME notices for things which
5483 should be worked on the near future. Delete lots of old
5484 useless (1.36 PA-SOM) code.
5486 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type

5513 a multiple of the section alignment rather than always a
5516 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5517 bits are zero (eg they specify no relocations), then do not even
5518 bother adding their entries to thesymextn section.

5562 of text, data and bss sections to 4.
5563 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5565 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5566 ELF, since the ELF object format does not have these type of
5567 relocations. Change the abort into as as_bad and return
5568 BFD_RELOC_NONE to silence compiler warnings.
5569 (md_assemble): Keep track of the instruction size. Allow white
5570 space between the $ and the constant for compatibility with older
5571 gases and other assemblers.

6535 w/ ANSI, and which weren't needed anyway
6537 Wed Jul 28 16:34:55 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
6539 * config/obj-elf.h (obj_frob_symbol): Renamed from tc_frob_symbol,

6581 are also magic, and have special default flag settings.
6582 (obj_elf_frob_symbol): Since the return value from this function

6646 * Extensive changes to permit symbols to contain any expression
6647 type and to delay the computation of the expression until the
6648 value is actually needed. This permits setting symbols to values
6649 calculated based on object code size. Expressions were changed to
6650 no longer be in a section, to stop the overloading of segment and
6651 expression type that previously occurred.
6653 * as.c (big_section, pass1_section, diff_section, absent_section):
6655 (expr_section): Added (used for dummy symbols which hold

7918 references don't appear to work right.
7920 * as.h (const, volatile): Put these definitions back, and use
7923 * doc/as.texinfo: First pass at using new texinfo features --
7924 variables, conditional tests. Far from complete.

7950 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
7951 the bottom (make expands variables in dependencies when the
7952 dependencies are read, not when they are used).
7954 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
7955 a29k .bss section; the mondfe program doesn't like it.

7976 source directory, if that's not the current directory.
7978 * configure.in (per-host): Accept MIPS host with BSD version

8000 process relocs if there aren't any relocs to process. Avoids
8001 malloc/free bug on SCO too.
8003 * as.h: Move local include files below system include files, to
8004 avoid some redefinition complaints on some systems.
8005 (const, volatile): Don't need these conditionally defined if we
8006 use CONST and VOLATILE from ansidecl.h.
8007 (seg_name): Use CONST, not const.
8009 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
8011 * config/tc-mips.c: Reindented to GNU standards.
8013 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
8015 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
8016 (fixup_segment): Add a29k special case; the linker is not prepared
8017 to see a segment offset here.
8019 * app.c (do_scrub_next_char): Added new state, 10, modifying state
8020 9 to only keep a space in between identifier characters.
8022 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
8024 * Makefile.in: add dvi target; as-$(config).texinfo might live in
8025 srcdir, might be in objdir.
8027 * doc/Makefile.in: dvi depends on as.dvi

8045 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
8046 bignums, but don't emit error message.
8048 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
8050 * Makefile.in (targ-cpu.o): Depend on config.h.
8052 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
8054 * app.c (do_scrub_next_char): Added new state, 9, to avoid
8055 dropping a space immediately following an identifier.
8056 * expr.c, write.c: Rewrote assert expressions to not use multiple
8057 lines; I don't think that can be done portably.
8058 * config/tc-mips.c (macro): Use $AT if target register is zero in
8059 load instruction, which it can be for a floating point load.
8061 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

8069 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
8072 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
8073 z8k-opc.h, not z8k.h.
8075 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
8078 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8080 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
8082 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
8084 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
8085 to be on a single line.

8133 prototypes for all static functions. Moved existing minimal
8134 debugging format support info #ifndef OBJ_ECOFF blocks.

8136 does not support a non sign extended high 16 bits reloc. Adjusted
8137 all callers accordingly.
8138 (tc_get_register): Renamed from get_register, and made non-static.

8183 * make-gas.com: Find obstack.obj if it's not in the current
8185 * read.c (s_ignore): Don't declare is_end_of_line. It's
8186 redundant, and triggers a VMS gcc compiler bug.
8188 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8189 current segment as an argument. (Ignored in all cases but VMS.)
8190 All callers and definitions changed.

8209 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
8210 Call elf_xstabs for .stabs and .xstabs operators.
8212 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
8214 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8217 * configure.in: mips-bsd configuration was missing format spec.
8220 * Makefile.in (Makefile): Depends on configure.in.
8222 * config/tc-mips.c (append_insn): Don't check for alignment of
8223 frag in memory; alignment of instructions in section is a separate

8243 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8244 constants are accepted, but symbolic values are not. GCC will not
8245 generate the latter currently.
8247 * frags.c (frag_init): New function.
8248 (zero_address_frag, bss_address_frag): Now initialized at run
8250 * as.c (main): Call frag_init.

8294 (fixup_segment): Make sure common-section symbols get treated the
8295 same as undefined symbols.

8326 new section/subsection.
8328 * read.c: Don't include ctype.h.
8329 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
8330 for now; should be machine-dependent.
8332 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
8333 targets, forcing BFD use.

8355 (write_object_file) [! BFD_ASSEMBLER]: Call it.
8356 (relax_and_size_seg) [BFD_ASSEMBLER]: New function; relax section
8357 and set its size and flags.
8359 * struc-symbol.h (struct symbol) [BFD_ASSEMBLER]: Replace some

8500 * config/tc-sparc.c (architecture_requested, warn_on_bump,
8501 md_relax_table): Use default zero initialization.
8502 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
8503 latter, instead of selecting with preprocessor conditionals.
8505 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8507 * configure.in: recognise all sparclite variants
8509 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

8515 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8517 * expr.c (operand): If character other than comma or newline is a
8518 logical end-of-line character, use the newline case.
8519 From Eric Youngdale:
8520 (operand): Set X_add_number field for floating-point numbers.
8521 (operand): Treat zero byte as end-of-operand.
8523 * configure.in (per-target): Look for with_bfd_assembler option.
8524 For now, only accept "no", until the merge is done.
8526 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8527 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8528 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8529 * read.c: Finish conversion to S_* macros in the VMS only
8530 parts of the program. Add "const" modifier to hex_value.
8531 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
8533 * expr.c: Add "const" modifier to hex_value.
8534 * symbols.c: Finish conversion to S_* macros in the VMS only
8535 parts of the program. Add "const" modifier to
8536 md_[long,short]_jump_size. Remove declaration of const_flag
8537 (which will be declared in obj-vms.h).
8538 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8539 Fix arguments to VMS_write_object_file.
8540 * config-gas.com: New file. Script for VMS systems to set up the
8541 configuration to build gas for VMS, and create config.status.
8542 * make-gas.com: Redone to work with new scheme.
8543 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8545 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8546 will swap bytes if needed on a big endian system. Use throughout
8548 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8549 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8550 types of malformed stabs. Change parsing algorithm so that we are
8551 more certain of having all of the information that we need on hand.
8552 * obj-vms.c (final_forward_reference): New function, used to help
8553 resolve the data types of as many struct elements as possible
8554 when some part of the struct is not fully defined by the compiler.
8555 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
8557 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8558 as symbols as well in the object file. Look for external functions
8559 that start with "__vt.", and turn them into variables, since the
8560 g++ compiler is incapable of doing this.
8561 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8563 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8564 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8565 have the name of the source file yet.
8566 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8568 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8570 * read.c (s_data): Always use "data_section", since it'll map to
8571 SEG_DATA or SEG_E1 if needed.
8572 (s_lcomm): Likewise with bss_section.
8573 (s_fill): Use memset, not bzero.
8575 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8596 (section_alignment): Declare only if not BFD_ASSEMBLER.
8597 (big_section, reg_section, pass1_section, diff_section,
8598 absent_section, text_section, data_section, bss_section): If
8599 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8600 mapping to segT enum values.
8601 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8602 if these are used or defined, if BFD_ASSEMBLER.
8603 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8604 subseg_new split into two functions.
8605 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8607 * as.h (volatile): Don't define if already defined.
8608 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8610 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8611 declare with format attribute for -Wformat checking.
8613 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8615 * app.c, config/tc-*.c: Don't include read.h, since it is already
8618 * These are based on patches from Minh Tran-le
8619 <mtranle@paris.intellicorp.com>.
8620 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8621 obj_format coffbfd and gas_target i386coff for target.
8622 (i[34]86-*-isc*): New host (uses sysv).
8623 * config/i386aix.mt: Removed (no longer used).
8624 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8626 (LDFLAGS): Added, defined as -shlib.
8627 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8628 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8629 (DOT_LABEL_PREFIX): Define.
8630 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8631 name rather than L0\001.
8632 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8634 * symbols.c, symbols.h (local_bss_counter): Removed.
8635 * write.c (write_object_file): bss no longer uses
8636 local_bss_counter. Pass correct data and bss size to
8637 VMS_write_object_file.

8643 (size_section): Restored sanity check.
8644 (do_relocs_for): Base section address on s_paddr rather than
8645 computing it. Adjust a29k R_IHIHALF special case to account for
8646 section paddr (used to require paddr to be zero). If there are no
8647 reclos, set s_relptr to 0. Set relocation size in object_headers.
8648 (fill_section): Always set s_vaddr here, removing
8649 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8650 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8651 Set STYP_INFO for .comment.

8655 H_{SET,GET}_* macros.
8656 (do_linenos_for): Set lineno size in object_headers.
8657 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8658 set s_vaddr here. If string_byte_count remains 4, set it back to
8659 0, and only write strings out if there are some. Call
8660 fill_section before do_relocs_for and do_linenos_for.
8661 (obj_coff_section): Handle optional quoted second argument giving
8662 section characteristics.
8663 (obj_coff_bss): Added to handle .bss.
8664 (obj_coff_ident): Added to handle .ident (puts string in .comment

8667 (fixup_mdeps): Change to segment. Call frag_wane after
8669 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8670 adjustment (already happened only for common symbols, but this is
8672 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8673 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8684 (do_scrub_next_char): For \", return " not '.
8685 (symbol_chars): Now const.
8687 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8688 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8690 * config/obj-coff.h: Don't use #elif.
8692 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8693 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
8695 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
8697 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

8717 SEG_BSS, fill with NOP_OPCODE.
8718 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
8719 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8720 using ZERO_BASED_SEGMENTS.
8721 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8722 never set segment address for SEG_E2 (.bss) and don't write out
8723 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8724 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8725 definitions, and don't merge tags with non-tags. Check for .bf
8726 rather than just checking whether the second character is b and
8727 the third character is f.
8728 (obj_coff_val): gcc can generate values which we don't handle
8729 correctly; discard information for now, since it only affects the
8730 debugging information.
8731 (tag_find_or_name): Don't insert tags in the symbol table.
8732 (yank_symbols): Don't merge labels.
8733 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8911 consistently const, and always initialized them. Included read.h.
8913 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
8915 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8916 constant will not fit in an immediate field.
8917 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
8919 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

8939 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
8941 * version.c: Put conditional "const" before version_string, not

8945 printed rep of null character.
8947 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
8949 * obj-coffbfd.c (write_object_file): check return value of
8952 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8954 * Support for i386-sysv.
8955 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
8956 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
8957 be used to set them all to zero as was done before.

8959 (fill_section): Don't set STYP_NOLOAD for .bss section.
8960 (fixup_segment): 386 uses strange common symbol format.

8993 * tc-z8k.c: lots of bug fixes
8995 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8997 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8998 #elif, since it is not supported by old compilers.
8999 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
9000 couple of expressions in tc-m68k.c.
9002 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9004 * read.c (cons): If NO_RELOC is defined, use it.
9006 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
9008 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
9010 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
9011 local labels to start with a .) and set REGISTER_PREFIX to %.
9012 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

9030 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9031 sections starting from zero, rather than making them consecutive.
9032 This makes subsequent reloc calculations easier, esp if the object
9033 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9034 allocate lcomm in .data rather than in .bss. It seems that some
9035 tools can't cope with a non-zero sized bss before linkage.
9037 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9039 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

9058 * Makefile.in (install): if $(tooldir) exists, install as in
9061 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
9063 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9064 .word is < -32768 or > 32767. The -J flag causes the error to be
9065 ignored. This is to catch over-sized switches generated by gcc on
9066 systems which don't support the broken .word hack.
9067 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9068 write.c (fixup_segment): check for signed .word overflow if
9069 WARN_SIGNED_OVERFLOW_WORD.
9071 * write.c (fixup_segment): fixed missing parens in expression

9086 * tc-i386.h : new coff defines
9088 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
9090 * input-scrub.c (input_scrub_push): call input_file_begin, not
9092 messages.c (as_perror): print ": " between the passed in error and
9093 the strerror, like perror does.
9095 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
9097 * Makefile.in: use gas_target instead of modifying target_cpu.
9098 From Steve Chamberlain:
9099 Makefile.in: Handle m68*-*-coff*.
9100 read.c, read.h: add mult argument to s_space
9102 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
9103 Motorola and MIT syntax; gas can now assemble either type of
9105 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

9111 (write_object_file) call fixup_mdeps
9112 (fixup_segment) set fx_subsy to 0.
9113 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9115 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9118 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9120 * Makefile.in (LIBS): Include opcode library.

9145 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9147 * config/tc-m68k.c (init_table): Now const. Always include 68851
9148 data, so that "bc" is available to 68040 cache instructions.
9149 Added "tt0", "tt1", and 68ec030 variants.
9150 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9151 (enum _register): Added TT0, TT1.
9152 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9153 line number correctly in "internal error" messages. Don't print
9154 architecture-mismatch message for operand errors.
9156 From Colin Smith (colin@wrs.com):
9157 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

9179 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9180 has already been formatted (but may still contain %-characters).
9183 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9185 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9186 written with indirection on the last two operands, which can be
9187 either data or address registers. Added a new operand type 'r'
9188 which accepts either register type. Added '(' to notend stuff in
9189 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9207 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
9208 their not having symbols associated.
9210 * tc-i960.c (norelax, instrument_branches): Default initializer is

9236 being used with args swapped, causing occasional lossage when
9237 refilling buffers after an include file.
9239 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
9241 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
9242 version. Discard bogus DONTDEF version.

9247 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
9248 selected architecture, print a message saying so and listing what

9295 * expr.c (floating_constant): Separate "=-" to avoid confusing
9296 ancient or broken compilers.
9298 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
9299 processor/opcode mismatch, so reword the error message.
9300 (md_assemble): If no CPU has been set (even if FPU/PMMU
9301 characteristics have been), default to 68020. Don't need extra
9302 quotes around error string.

9360 * write.c (write_object_file): various changes to handle data in
9361 the BSS segment in much the same was as stuff in the DATA segment.

9371 * expr.c(expr): allow SEG_REGISTER in expressions.
9372 * read.c(pseudo_set): register expressions can be the source of a
9374 * subsegs.c (subseg_new): Now -R forces all changes to SEG_DATA to
9375 goto SEG_TEXT (if a.out)
9376 * write.c (write_object_file): If a.out don't use the old way for
9378 * config/obj-a.out (s_sect): complain if the user tries to use a
9379 subsegment with a value which might interfere with out -R hackery.
9380 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
9381 rather than use ugly if tree. (init_regtable): insert register
9382 names into symbol table.
9384 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
9386 * write.c (write_object_file): keep the fix_tail clean, which
9387 fixes a bug in -R where relocations were being lost.
9389 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
9391 * configure.in: recognize m680x0 as having sun3 emulation mode for

9414 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9416 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
9417 calc the base of relocs correctly.
9418 * tc-a29k.c (parse_operand): allow expressions to be in any section.
9420 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
9422 * as.c, write.c: use -K rather than -k for the broken word warning
9425 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)

9433 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9435 * write.c (write_object_file): For b.out format, round up section
9436 start addresses to match required alignment.
9438 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9440 * Makefile.in (install): Install into $(tooldir)/bin, since that's
9441 where gcc looks for it.
9443 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
9445 * Makefile.in: Changed some lines to be less confusing for some
9448 * input-file.c: Conditionalize on _IOFBF, not VMS.
9450 * read.c, write.c: Change a series of ifdef/elif to
9451 ifdef/else/ifdef etc.
9453 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)

9470 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
9472 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
9473 tc-m68k.h to te-sun3.h.
9475 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
9477 * configure.in: vxworks68 gets te-sun3.h.
9479 * expr.c: remove limitation that local_labels_dollar or
9480 local_labels_fb must be < 10.
9482 * symbols.c: remove local_labels_dollar, replace with a function
9483 interface for a sparse array. All users adjusted.
9485 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
9487 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9489 * doc/Makefile.in: commented out line for building as-all.texinfo.
9492 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
9494 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

9508 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9511 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9513 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9515 * expr.c (operand): if can't work out what sort of operand it is,
9516 then look through FLT_CHARS for a hint.
9518 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9520 * Makefile.in, configure.in: removed traces of namesubdir,
9521 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9522 copyrights to '92, changed some from Cygnus to FSF.
9524 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9525 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9526 copyrights to '92, changed some from Cygnus to FSF.
9528 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9530 * expr.c: If an expression is single comma, then return with
9531 SEG_ABSENT rather than an error - since the sparc front end does
9532 really strange things with things like fbge,a
9534 * as.h: include bfd.h if using many sections
9535 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9536 local labels didn't work.
9537 * listing.c (list_symbol_table): don't core dump when there's no
9539 * write.c, write.h: call fix_new with the right number of args on
9541 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9544 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9546 * app.c: MRI compatibility - allow single quote to start a string.
9547 * as.c: fix typo recently introduced.
9548 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9549 * expr.c: Much rewriting, to accomodate MRI syntax for
9550 expressions. Also easier to read now.
9551 * listing.c: Put back defuns
9552 * read.c: modified to accept MRI syntax, put back listing pseudo
9553 ops so that an assembler built with NO_LISTING ignores list ops
9555 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9556 machine is a SPARC or a 29K.
9557 * config/obj-aout.c: added s_sect pseudo op
9558 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9559 fill in the timestamp.
9560 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9561 anymore, define all the relocs which the tc-<x> bit will use so we
9562 can translate from them to the coff types.
9563 * config/tc-a29k.c: reloc_type isn't ane enum any more
9564 * config/tc-m68k.c: Added NO_RELOC definition.
9566 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9568 * Makefile.in: put header files before C source for TAGS; remove
9569 references to non-existent syscalls.h.
9571 * read.c, write.c subsegs.c: back out the .bss changes.
9573 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9575 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9579 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9581 * symbols.c (local_label_name): symbols now start with ^A.
9583 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9584 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9585 generate these sections. .align: will use NOP_OPCODE or 0
9586 for padding. This is just for being nice to the
9589 * expr.c (operand): changed to generate local label "\001L0"
9590 starting with a ^A so that it is recognized as a local label.
9592 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9594 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9595 i/o opcodes - inb, inw, outb and outw. string manipulation with
9596 att syntax - scmp, slod, smov, ssca, ssto.
9598 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9599 to just after .file .
9601 In obj_crawl_symbol_chain() where it tries to put the external
9602 symbols apart, with the condition:
9603 (!S_IS_DEFINED(symbolP) &&
9604 !S_IS_DEBUG(symbolP) &&
9605 !SF_GET_STATICS(symbolP))
9606 it was moving too many symbols out. So I switch it back to the
9608 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9610 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9611 so that we don't use the F_RELFLG which make the linker complain
9612 that somebody has stripped the relocation info.
9614 Also, the AIX ld program require that the relocation table
9615 is sorted by r_vaddr like the standard ATT assembler does.
9617 [he also changed the sizeof(struct ...)'s into the coff
9618 style FOOSZ macros. I'm not sure this is right, but I can't
9619 remember why. xoxorich.]
9621 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9623 * Makefile.in, configure.in, doc: use the doc. Build it, install
9626 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9628 * read.c: white space and comments only.
9630 * configure.in: use the new atof-ns32.c for ns32k.
9632 * write.c: comment change only.
9634 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9635 aren't yet integrated.
9637 * tc-i860.[hc]: blew off the dust. Something must still be done
9638 about conflicting relocation types.
9640 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9643 * tc-i960.c, tc-sparc.c: white space and comments only.
9645 * tc-a29k.h: delete duplicate macro definition.
9647 * new file atof-ns32k.c copied from hack's last unreleased gas.
9649 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9651 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9654 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9655 ChangeLog's prior to this are sketchy at best. I have logs.
9656 They just aren't ChangeLogs.
9663 version-control: never
