988 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
990 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
991 it's better to use the one in libiberty.
993 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
995 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
996 change; it breaks the rs6000 support, and doesn't seem to be
999 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1001 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

1007 rather than explicitly adding the frag address.
1008 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
1009 the end of the line numbers; this replaces the zero entry which
1010 used to be added by coff_add_linesym, removed Oct 7.
1011 (coff_adjust_section_syms): Ignore sections with no seginfo.
1013 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1015 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a

1017 instead in the -B options.
1018 (comparison): Revert yesterday's change.
1020 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1022 * config/tc-sparc.c (tc_gen_reloc): For non-a.out relocations, if

1027 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
1028 for an embedded PIC switch expression, since the definition of
1029 S_IS_LOCAL was changed.

1033 * Makefile.in (comparison): When comparing as.new or gasp.new, try
1034 running the binary through sed to avoid differences due to
1035 "stage1" or "stage2" having been written into the binary.
1037 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1039 ELF symbol size handling, based on code from Eric Youngdale:
1040 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an
1041 expression pointer to the symbol structure, used for `size'
1042 expressions that couldn't be reduced to constants when initially
1044 (elf_frob_symbol): Declare.

1047 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
1049 (obj_elf_size): Deleted unused code. If size is non-reducible
1050 expression, allocate some storage for the sy_obj field and copy
1052 (elf_frob_symbol): New function. Computes sizes, calls
1053 ecoff_frob_symbol if appropriate.
1055 * write.c (fixup_segment): For i386 elf and coff (for now), don't
1056 add in value of symbol from another defined section of the file.

1081 * config/obj-vms.h (S_IS_LOCAL): fix obsolete flagseen[] reference.
1083 Wed Oct 5 11:49:26 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
1085 * config/obj-ecoff.c (obj_pseudo_table): Accept .esize and .etype

1102 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
1104 (diststuff): New target; builds DISTSTUFF.
1105 (realclean): Separate target, depend on clean and distclean, then
1107 * make-gas.com: Deleted.

1110 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
1112 (i386_operand): Don't look up section symbol for
1114 (reloc): Always permit return of 8- and 16-bit relocation types.
1115 Add a space after "pc-relative" in the error message.
1116 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1117 BFD_RELOC_386_GOTOFF relocs.

1121 (TC_VALIDATE_FIX): New macro -- call it.
1122 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

1125 it rather than stdarg.h.
1127 * write.h (struct fix): Added new bitfield fx_plt, for fixups
1128 referring to PLT entries.
1129 * write.c (fix_new_internal): Initialize fx_plt to zero.
1130 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
1131 Don't adjust fx_offset by frag address, since S_GET_VALUE now
1132 includes the frag address.
1133 (fixup_segment): Changed local var PCREL to type int, added PLT.
1134 If PC-relative fixup refers to a PLT entry for a symbol in the
1135 current section, don't reduce it.

1138 DEBUG5 is defined, print out each fixup before and after
1140 (fixup_segment): If DEBUG5 is defined, print out each fixup before
1141 and after processing.
1142 (print_fixup): Added prototype. Show address on first line. Show
1143 fx_offset and fx_subsy. [!BFD_ASSEMBLER]: Only show fx_r_type if

1157 Show fx_r_type and fx_addsy fields.
1159 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1161 * configure.in: Set bfd_gas for all sparc targets in one place,
1162 instead of separately for each. Correctly handle user-supplied
1163 "--enable-bfd-gas" option.
1165 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1167 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
1170 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
1171 processing if add_symbol is undefined or in expr_section.

1173 constant-valued symbol, convert to O_symbol and re-reduce.
1174 (S_GET_VALUE): If symbol needs resolving, resolve it.
1175 (indent_level): No longer static.
1176 (print_symbol_value_1): Don't print frag address if it matches
1177 zero_address_frag. Don't print "resolving" if already resolved.

1180 (print_expr_1): Fix whitespace before printing X_add_number.
1182 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1183 not symbol_new, for symbols holding expression values.
1184 * expr.h (make_expr_symbol): Move declaration here.
1185 * write.c (fix_new_exp): Handle O_add by creating an
1186 expression-valued symbol, and calling fix_new_exp recursively.
1187 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1188 undefined symbol and a constant, fold the constant into the fixup,
1189 and refer to the undefined symbol directly. Then process the
1190 fixup again from scratch.
1191 (write_object_file): Before calling adjust_reloc_syms, make a pass
1192 through the symbol list trying to resolve values.
1194 * write.c (print_fixup): New routine, for debugging.
1195 (write_relocs): Call bfd_install_relocation. Deleted various
1196 hacks for working around problems with bfd_perform_relocation.
1198 * Makefile.in (VERSION): Update to 2.4.90.
1200 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1202 * Makefile.in (gasp.o): Depends upon config.h.
1204 * config/tc-mips.c: Include subsegs.h.
1205 (md_apply_fix): If an unconditional b or bal overflows, and we are
1206 not assembling PIC code, replace it with a j or jal.
1208 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1209 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
1211 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1213 * write.c (write_relocs): Add file name and line number to
1214 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1215 RELOC_EXPANSION_POSSIBLE.
1217 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1219 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1220 here. Use them for deciding which PRINTF*LIKE macro definitions
1222 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1223 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1224 default definitions matching what we were doing before.
1225 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1226 always use the varargs form if not using stdarg. It's safe to
1227 always use vfprintf, because libiberty will provide it if the
1228 native system doesn't. Also, always make format be const.
1229 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
1231 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1244 (listing_newline): Check filename as well as line number when
1245 deciding whether to record it.
1246 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1247 false (if defined) as well as checking for reg_section.
1248 (listing_listing): Iterate fetching lines while line number is too
1249 low, and we haven't run off the end of the input file.
1251 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1253 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1255 * ecoff.c (ecoff_generate_asm_lineno): check if
1256 current_stabs_filename is NULL before strcmp.
1257 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
1260 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1262 * config/ho-*.h: Now-unused files deleted.
1264 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1265 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1266 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1267 zero. Don't call obj_frob_forward_symbol.
1268 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1269 X_add_number is zero.
1270 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1272 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1274 (strchr): Don't declare.
1275 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
1276 md_estimate_size_before_relax, md_ri_to_chars,
1277 md_create_short_jump, md_create_long_jump.
1278 (brtab_emit): Use data_section, not SEG_DATA.
1280 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1282 * config/vms-conf.h: new file, manually derived from conf.in.
1283 * config-gas.com: use it, and eliminate obsolete "host.h".
1285 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1287 * config/tc-ppc.c (ppc_current_block): New static variable.
1288 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
1289 ppc_current_block. Don't move around any stab symbol, just those
1291 (ppc_bs): Set ppc_current_block.
1292 (ppc_es): Clear ppc_current_block.
1293 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1294 from the csect of the enclosing block.
1296 * config/tc-mips.c (insns_since_cache_access): Remove.
1297 (append_insn): Remove setting of insns_since_cache_access, and
1298 special 4600 handling; it turns out not to be required.
1300 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1302 * config/tc-mips.c (md_shortopts): Remove E.
1303 (md_longopts): Add EB and EL.
1304 (md_parse_option): Handle -EB and -EL as separate options, rather
1305 than as a single -E option with an argument.
1307 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
1309 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
1310 involving global symbols too.
1312 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1314 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1316 * configure.in: Test for remove, not delete. Fix cross-assembler
1318 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1321 * read.c (pseudo_set, case O_symbol): If
1322 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1323 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1324 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1326 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1328 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1329 many others): new macros; values obtained from "DSTRECRDS.SDL".
1330 * config/obj-vms.h (various): use them.
1331 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1332 representation (only enum bitfields can avoid being bitstrings).
1333 (bitfield_suffix, setup_basic_type): new routines.
1334 (VMS_typedef_parse): use them. Now recognize bitfields of all
1335 integral types, not just type `int'. Caveat: the representation
1336 used for bitfields still does not work for objects placed in
1337 registers, and gcc's optimizer sometimes puts small structs there.
1339 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1341 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1342 bit from const_flag.
1343 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1344 (tc_frob_label): define this to call vms_check_for_special_label,
1345 and declare the latter.
1346 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1348 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1349 (vms_check_for_special_label): new routine (tc_frob_label).
1350 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1351 and `gcc2_compiled.' labels; they won't reach here any more.
1352 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1353 double', use `vax_g_doubles' flag to select type of double.
1354 (VMS_write_object_file) [traceback setup]: don't pass symbols
1355 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1356 and TBT_Routine_End functions.
1358 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
1360 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1361 S_GET_VALUE() to avoid many repeated function calls.
1362 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1363 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1364 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1365 be obsolete; gcc does it automatically for vms target. It's
1366 also misnamed, because it is for the "VAX C" run-time library,
1367 not the newer "DEC C" one which has much different startup code.]
1368 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1369 `S_GET_xxx(symbol) = new_value'.
1371 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1373 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1374 not &bfd_abs_section.
1376 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1378 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1380 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1382 * expr.c (expr): Don't reduce the difference of two symbols in the
1383 same frag if the symbols are not in normal sections.
1385 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1386 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1387 (obj_attach_unwind_info): Do not define. Not needed anymore.
1388 * config/tc-hppa.c: Delete whitespace at EOL.
1389 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1390 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1391 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1392 fixups, store 32bits of unwind information in the fx_addnumber
1394 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1395 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1396 pointer to 32 bits of unwind info.
1397 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1398 pointer to the dummy symbol; set the addend field to fx_addnumber.
1399 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1400 rather than &bfd_XXX_section.
1402 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1404 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1405 value by one; discard adjustments previously being made. From
1408 VMS- and Vax-related changes from Pat Rankin:
1409 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1410 * vmsconf.sh: no longer have make-gas.com echo text about needing
1411 to modify the gcc-vms driver when intending to use with gcc 1.x.
1412 * as.c (parse_options): suppress 'v' from std_short_options and
1413 eliminate VMS-specific conditional initialization;
1414 [default case]: check for '-v' if md_parse_options doesn't recognize
1416 [default case, #if VMS]: check for filename argument when '-v' seen;
1418 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1419 for O_big literal operands (double floats and long long ints);
1420 [VMS, md_shortopts]: add second colon after 'v';
1421 (md_parse_options) [VMS, case 'v']: check for argument, so
1422 caller can handle `-v' w/o arg.
1424 Tue Sep 13 16:45:08 1994 Steve Chamberlain (sac@jonny.cygnus.com)
1426 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET
1427 is defined, put the tx_offset into the r_offset.

2473 (control_regs): New pointer.
2474 (m68k_ip): Use control_regs instead of testing CPU every time.

2824 * config/obj-ecoff.c (ecoff_frob_file): Use bfd_ecoff_set_gp_value
2825 and bfd_ecoff_set_regmasks to set the GP value and the register
2826 masks, rather than using the now obsolete fake .reginfo section.
2828 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2830 * listing.c (list_symbol_table): Don't print register symbols as
2833 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
2834 underscores, since symbol_new will already have done it.
2835 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
2837 * as.c (main): If tc_init_after_args is defined, invoke it after
2838 all arguments have been processed.
2840 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
2841 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
2842 section instead of .text. Call create_target_segments.
2843 * read.c (demand_copy_string): No longer static.
2845 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2847 * config/tc-mips.c (append_insn): Permit branches to be switched
2848 with the preceding instruction even if .set nobopt has been seen.
2849 .set nobopt actually controls whether to bring up an instruction
2850 from the branch target, which gas does not currently support.
2852 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2854 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

2867 * config/tc-sparc.c (md_section_align): Always round up to
2868 multiple of alignment power specified in bfd target vector.
2870 * gasp.c: Include ctype.h.

2881 register mask, skip empty fill frags caused by enabling listing
2884 * config/ho-sysv.h: Include string.h.
2886 * doc/internals.texi: New (well, recently added) file. Just added
2887 info on as_warn and friends.

2891 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
2892 defaults for defined, private, and spnum fields for the
2893 $TEXT$ and $PRIVATE$ spaces. Do not clobber spnum. Do
2894 not reset the segment if just updating a space.
2895 (pa_spaces_begin): Set BFD section flags for all built-in
2898 Fri Apr 15 10:51:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

2901 (add_procedure): Set first_proc_ptr if it hasn't been set.
2902 (ecoff_build_lineno): If the first procedure does not start at
2903 address zero, insert a dummy line to compensate.
2905 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
2908 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2910 * expr.c (operand): Try to parse "0f" and "0b" sequences as
2911 floating point and binary numbers respectively; if it doesn't
2912 work, treat them as local labels.
2914 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
2915 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2917 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2919 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2920 source files from other directories into objects in the current
2921 directory, and specify PSECT attributes explicitly to linker.
2922 Also added missing label.
2923 * Makefile.in (stamp-mk.com): Reference new variable
2924 VMS_OTHER_OBJS for list of non-local object files, instead of
2926 (VMS_OTHER_OBJS): New variable, added more libiberty files.

2936 * Makefile.in (de-stage1, de-stage2, de-stage3): Use rm -f.
2938 * config/tc-mips.h (DIFF_EXPR_OK): Define.
2939 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
2940 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
2941 argument, the reloc type.
2942 (load_register): Pass reloc type to macro_build for 'u'.
2943 (macro): Likewise. For M_LA_AB permit a difference expression
2944 when generating embedded PIC code between an arbitrary symbol and
2945 a symbol in the .text section.
2946 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2947 BFD_RELOC_PCREL_LO16 to be emitted.

2951 BFD_RELOC_PCREL_LO16 and BFD_RELOC_PCREL_HI16_S.
2953 Tue Apr 12 18:25:13 1994 Stan Shebs (shebs@andros.cygnus.com)
2955 * subsegs.c (subsegs_begin): Call memset with args in the correct
2957 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2958 to NULL instead of 0.
2960 Mon Apr 11 09:00:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2962 * config/tc-hppa.c (pa_procend): Handle case where label was
2963 defined after the .proc directive.
2965 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
2966 procend for a procedure without a name.
2968 Thu Apr 7 14:28:30 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2970 * config/tc-mips.c (macro): Pass NULL for expression argument to

2987 (hppa_tc_symbol): Likewise.
2989 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2990 elf_tc_make_sections stuff. It was there to support PA braindamage
2991 which has been fixed, and in the case of elf_tc_make_sections is
2992 redundant with elf_tc_final_processing.
2994 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2996 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the
2999 Tue Apr 5 15:48:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3001 * config/tc-mips.c (mips_ip): For case 'o', when generating
3002 embedded PIC code, accept the difference between two local symbols
3004 (mips_force_relocation): Only force a reloc to be generated for a
3006 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
3007 value into the file if the fixup will not generate a reloc.
3009 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
3011 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
3012 don't spew remainder of input file in error message.
3013 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3014 message with reloc type and try to process remainder of file.
3016 * doc/Makefile.in (install-info-as, install-info-gasp): New
3017 targets, now explicitly checking $(srcdir) for info files.
3018 (install-info): Depend on both of them; do nothing more.
3020 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
3022 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
3024 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3026 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
3027 flag rather than signedp field. Only permit extended range if
3028 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
3029 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
3031 * config/tc-ppc.c (ppc_size): New static variable.
3032 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
3033 (md_begin): If an instruction has a size specific flag set, only
3034 add it if we are assembling that size.
3036 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3038 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3039 cross section PC relative relocs right for COFF and ELF.
3041 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3043 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
3044 (OBJ_PROCESS_STAB): Don't define.
3046 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3048 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3049 the type of symbol set symbols which happen to be in the absolute
3050 or undefined section.
3052 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
3054 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3055 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3056 and -many (all architectures).
3058 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3060 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
3061 involving a function symbol which is not a plabel to zero.
3062 (md_apply_fix): Never pass a function symbol to field_adjust.
3064 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3066 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3067 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3069 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3070 branch with an instruction that uses $at, in case the branch is
3072 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3073 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3074 to make it pcrel_offset.
3075 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3076 reloc->address; another gruesome hack to get gas reloc handling to
3079 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3081 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3084 (emit_insn): New function.
3085 (md_assemble): Call it.
3086 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3088 (lituse_pending): New variable. Set by anything that generates a
3089 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3090 tested by code that might want to emit a LITUSE reloc.
3091 (emit_unaligned_io): New function. Currently calls md_assemble,
3092 but it should eventually be converted to generate the insn itself
3093 and call emit_insn directly.
3094 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3095 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3096 emit_bis_r): Likewise.
3097 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3098 (alpha_ip, label get_macro): Don't emit the final instruction if
3100 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3101 unaligned memory access macros.
3102 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3103 the value can't be resolved.
3105 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3107 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3108 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3109 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3111 (mips_force_relocation): New function.
3112 (md_apply_fix): Set fixP->fx_done appropriately.
3113 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

3121 * config/tc-mips.c (enum mips_pic_level): New enum.
3122 (mips_pic): Change from int to enum mips_pic_level. Change all
3123 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3124 (load_address): Handle EMBEDDED_PIC.
3125 (macro): Handle EMBEDDED_PIC in all PIC cases.
3126 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3127 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3128 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3129 works). Do not permit -G with SVR4_PIC.
3130 (s_abicalls): Warn if -G was used, and force -G 0.
3131 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3132 anything but a.out, not just for ELF. For ECOFF, don't generate a
3133 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3135 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3137 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3139 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3140 parameters to avoid losing when compiling with HP CC.
3141 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3143 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3145 * Makefile.in (config-stamp): If `defs' is defined, emit a
3146 preprocessor directive to create a macro named by this value into
3147 config.new; don't explicitly go for BFD_ASSEMBLER.
3148 * configure.in: Define `defs', not `BFDDEF'. Set it to
3149 MANY_SEGMENTS for any obj-coffbfd target.
3150 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3151 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3153 (LOCAL_LOADLIBES): Deleted.
3154 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3155 * config/m88kcoff.mt (TDEFINES): Ditto.
3156 * config/ebmon29k.mt: Deleted.
3157 * config/h8300hds.mt: Deleted.
3158 * config/ic960coff.mt: Deleted.
3159 * config/sparc.mt: Deleted.
3160 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3161 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3162 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3163 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

3181 bfd_set_symtab is called.
3182 (dump_section_relocs): Note whether a symbol is a section symbol
3184 (adjust_reloc_syms): For now, always supply an absolute symbol for
3185 fixups without symbols but not yet `done'. Use section_symbol to
3186 get the symbol, instead of going directly for abs_symbol.
3187 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3188 reloc is not a section symbol and is not in the symbol table.
3189 (set_symtab): New function, broken out from write_object_file.
3190 Counts symbol table instead of relying on an earlier count.
3191 (write_object_file): Call set_symtab, but do it after potentially
3192 invoking the *_frob_file macros. Don't bother counting symbols.
3193 Call symbol_remove, instead of expanding it in place. Moved the
3194 conditionalized `object_file_size' declaration down to
3195 conditionalized block where it's used. When using the absolute
3196 symbol for a fixup without a symbol, set sy_used_in_reloc.
3197 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3198 the correct symbol for the absolute section.
3200 * subsegs.c (section_symbol): Use symbol_new instead of
3201 symbol_make, since we may want it to go into the symbol table.
3202 Make the new symbol have internal linkage. If
3203 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3204 symbol with the newly created GAS symbol.
3205 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3206 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
3208 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
3210 * config/tc-sparc.c: Include subsegs.h.
3211 (in_signed_range): New function.
3213 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3214 (sparc_ip, label "immediate"): Reject constants for pcrel
3215 instructions only if the relocation type indicates a "call"
3216 instruction and the offset is within range of a "jmpl %g0". If
3217 it's not in range, use the absolute section symbol plus an offset.
3218 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3220 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3222 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3225 * configure.in: Eliminated all targets using obj-coff but not
3226 defining BFD_ASSEMBLER; I think all such targets that are
3227 supported will be matched by real CPU-OS combinations earlier in
3229 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3230 some comments about the dpx2 configuration, but left it disabled,
3231 since it couldn't be reached before.
3232 (target a29k-amd-ebmonold): Deleted.
3234 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3236 * config/tc-hppa.c (pa_import): Correctly handle importing of an
3237 already defined symbol.

3241 * config/tc-mips.c (mips_ip): Only accept overly large values for
3242 the 'j' operand if there are no further alternatives for this
3245 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3246 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3247 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3249 * config/tc-mips.c (mips_align): Take new argument, label, and use
3250 it instead of global insn_label.
3251 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3252 call to mips_emit_delay and pass it to mips_align.
3254 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3256 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3258 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3259 argument to a .callinfo directive. Don't loop forever on errors.
3261 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3262 use pre-defined registers as arguments.
3264 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3266 * write.c (write_object_file): Check both S_IS_LOCAL and
3267 S_IS_EXTERNAL when deciding whether to discard a symbol.
3269 * config-gas.com: Scan Makefile.in, not version.c, for current
3270 version number. Delete all versions of temp files when finished
3271 with them. Create config.h.

5047 of interest to the linker. ENTRY/EXIT relocations for SOM are
5048 an example of marker relocations.

5078 BFD_RELOC_MIPS_GPREL. Added new case a.
5079 (set_at, load_register, macro): Changed calls to macro_build to
5080 pass new argument for i, j and o cases.
5081 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
5082 special handling when generating SVR4 PIC code.

5416 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5418 * configure.in: Set bfd_gas for all sparc targets. Added facility
5419 for keeping or rejecting configurations still under development;
5420 default is to assume production environment, and reject configs
5421 still being worked on. Mark Elf configurations (except sparc and
5422 i386) as developmental. Deleted cases matching some generic names
5423 in favor of more specific names. (E.g., when we get Alpha

5440 through inclusion of tc-hppa.h. Delete all forward declarations
5441 for functions only used within tc-hppa.c, likewise for structures,
5442 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5443 conditional code in a few small places.
5445 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5446 structures, global variables, forward declarations together.

5448 conditional code -- try to group conditional code together
5449 into a few places. Make all functions and variables which
5450 are only used within tc-hppa.c static. PARAMize all functions.
5451 Add comments to functions. Delete unused functions, variables,
5452 #defines, etc. Delete unused members within structures. Delete
5453 ldil;ble hacks -- it is believed they were installed to work
5454 around old gas bugs. Avoid using mixed case for local
5455 functions, variables, and structures. Fix formatting problems
5456 not found by GNU-indent. Add FIXME notices for things which
5457 should be worked on the near future. Delete lots of old
5458 useless (1.36 PA-SOM) code.

5537 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5539 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5540 ELF, since the ELF object format does not have these type of
5541 relocations. Change the abort into as as_bad and return
5542 BFD_RELOC_NONE to silence compiler warnings.
5543 (md_assemble): Keep track of the instruction size. Allow white
5544 space between the $ and the constant for compatibility with older

6508 * config/ho-sunos.h: remove some old function decls that conflict
6509 w/ ANSI, and which weren't needed anyway
6511 Wed Jul 28 16:34:55 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
6513 * config/obj-elf.h (obj_frob_symbol): Renamed from tc_frob_symbol,

6554 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
6555 are also magic, and have special default flag settings.
6556 (obj_elf_frob_symbol): Since the return value from this function
6557 isn't used, don't bother calling obj_elf_write_symbol_p, since it
6558 doesn't accomplish anything else.

6570 undefined_section for the return value.
6572 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
6573 pseudo-op with a poc_handler field of NULL, ignore it and treat it
6574 as an instruction instead.

6590 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
6591 case to set obj_format=elf. Must go before i386-*-sysv* case that
6592 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
6593 *-*-solaris case, and move to before *-sysv* case that wants to
6594 set obj_format to coff.

6620 * Extensive changes to permit symbols to contain any expression
6621 type and to delay the computation of the expression until the
6622 value is actually needed. This permits setting symbols to values
6623 calculated based on object code size. Expressions were changed to
6624 no longer be in a section, to stop the overloading of segment and
6625 expression type that previously occurred.
6627 * as.c (big_section, pass1_section, diff_section, absent_section):
6629 (expr_section): Added (used for dummy symbols which hold

6713 (previous_section, previous_subsection): New vars.
6714 (obj_elf_section): Save current place in case DWARF code wants us
6715 to pop back to it. Handle unquoted section name as well as quoted
6716 section name. Don't crash on invalid strings.
6717 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

6829 sy_resolved and sy_resolving single bit fields.
6830 * symbols.c (symbol_new): Don't initialize sy_forward field.

7922 Mon Mar 29 12:56:56 1993 Ian Lance Taylor (ian@cygnus.com)
7924 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
7925 the bottom (make expands variables in dependencies when the
7926 dependencies are read, not when they are used).
7928 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
7929 a29k .bss section; the mondfe program doesn't like it.

7950 source directory, if that's not the current directory.
7952 * configure.in (per-host): Accept MIPS host with BSD version
7954 (per-target): Classify i486 as i386. Use generic cpu_type instead

7973 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
7974 process relocs if there aren't any relocs to process. Avoids
7975 malloc/free bug on SCO too.
7977 * as.h: Move local include files below system include files, to
7978 avoid some redefinition complaints on some systems.
7979 (const, volatile): Don't need these conditionally defined if we
7980 use CONST and VOLATILE from ansidecl.h.
7981 (seg_name): Use CONST, not const.
7983 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
7985 * config/tc-mips.c: Reindented to GNU standards.
7987 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
7989 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
7990 (fixup_segment): Add a29k special case; the linker is not prepared
7991 to see a segment offset here.
7993 * app.c (do_scrub_next_char): Added new state, 10, modifying state

7996 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7998 * Makefile.in: add dvi target; as-$(config).texinfo might live in
7999 srcdir, might be in objdir.

8019 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
8020 bignums, but don't emit error message.
8022 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
8024 * Makefile.in (targ-cpu.o): Depend on config.h.
8026 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
8028 * app.c (do_scrub_next_char): Added new state, 9, to avoid
8029 dropping a space immediately following an identifier.
8030 * expr.c, write.c: Rewrote assert expressions to not use multiple
8031 lines; I don't think that can be done portably.
8032 * config/tc-mips.c (macro): Use $AT if target register is zero in
8033 load instruction, which it can be for a floating point load.
8035 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

8046 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
8047 z8k-opc.h, not z8k.h.
8049 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
8052 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8054 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
8056 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
8058 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
8059 to be on a single line.
8061 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8063 * Makefile.in (config.h): Create file, writing out definitions of

8103 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
8104 (struct loc, struct proc, struct file): Moved to tc-mips.c within
8105 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
8106 * config/tc-mips.c: Rearranged for ECOFF support. Added
8107 prototypes for all static functions. Moved existing minimal
8108 debugging format support info #ifndef OBJ_ECOFF blocks.
8109 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
8110 does not support a non sign extended high 16 bits reloc. Adjusted
8111 all callers accordingly.
8112 (tc_get_register): Renamed from get_register, and made non-static.
8114 * config/mips-big.mt, config/mips-lit.mt: New files. Define

8157 * make-gas.com: Find obstack.obj if it's not in the current
8159 * read.c (s_ignore): Don't declare is_end_of_line. It's
8160 redundant, and triggers a VMS gcc compiler bug.
8162 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8163 current segment as an argument. (Ignored in all cases but VMS.)
8164 All callers and definitions changed.

8183 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
8184 Call elf_xstabs for .stabs and .xstabs operators.
8186 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
8188 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8191 * configure.in: mips-bsd configuration was missing format spec.
8194 * Makefile.in (Makefile): Depends on configure.in.
8196 * config/tc-mips.c (append_insn): Don't check for alignment of
8197 frag in memory; alignment of instructions in section is a separate
8200 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

8217 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8218 constants are accepted, but symbolic values are not. GCC will not
8219 generate the latter currently.
8221 * frags.c (frag_init): New function.
8222 (zero_address_frag, bss_address_frag): Now initialized at run
8224 * as.c (main): Call frag_init.

8268 (fixup_segment): Make sure common-section symbols get treated the
8269 same as undefined symbols.

8302 * read.c: Don't include ctype.h.
8303 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
8304 for now; should be machine-dependent.
8306 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
8307 targets, forcing BFD use.

8474 * config/tc-sparc.c (architecture_requested, warn_on_bump,
8475 md_relax_table): Use default zero initialization.
8476 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
8477 latter, instead of selecting with preprocessor conditionals.
8479 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8481 * configure.in: recognise all sparclite variants
8483 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

8486 accidentally changed to use subseg_change where it should have
8489 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8491 * expr.c (operand): If character other than comma or newline is a
8492 logical end-of-line character, use the newline case.
8493 From Eric Youngdale:
8494 (operand): Set X_add_number field for floating-point numbers.
8495 (operand): Treat zero byte as end-of-operand.
8497 * configure.in (per-target): Look for with_bfd_assembler option.
8498 For now, only accept "no", until the merge is done.
8500 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8501 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8502 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8503 * read.c: Finish conversion to S_* macros in the VMS only
8504 parts of the program. Add "const" modifier to hex_value.
8505 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
8507 * expr.c: Add "const" modifier to hex_value.
8508 * symbols.c: Finish conversion to S_* macros in the VMS only
8509 parts of the program. Add "const" modifier to
8510 md_[long,short]_jump_size. Remove declaration of const_flag
8511 (which will be declared in obj-vms.h).
8512 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8513 Fix arguments to VMS_write_object_file.
8514 * config-gas.com: New file. Script for VMS systems to set up the
8515 configuration to build gas for VMS, and create config.status.
8516 * make-gas.com: Redone to work with new scheme.
8517 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8519 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8520 will swap bytes if needed on a big endian system. Use throughout
8522 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8523 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8524 types of malformed stabs. Change parsing algorithm so that we are
8525 more certain of having all of the information that we need on hand.
8526 * obj-vms.c (final_forward_reference): New function, used to help
8527 resolve the data types of as many struct elements as possible
8528 when some part of the struct is not fully defined by the compiler.
8529 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
8531 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8532 as symbols as well in the object file. Look for external functions
8533 that start with "__vt.", and turn them into variables, since the
8534 g++ compiler is incapable of doing this.
8535 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8537 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8538 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8539 have the name of the source file yet.
8540 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8542 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8544 * read.c (s_data): Always use "data_section", since it'll map to
8545 SEG_DATA or SEG_E1 if needed.
8546 (s_lcomm): Likewise with bss_section.
8547 (s_fill): Use memset, not bzero.
8549 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8570 (section_alignment): Declare only if not BFD_ASSEMBLER.
8571 (big_section, reg_section, pass1_section, diff_section,
8572 absent_section, text_section, data_section, bss_section): If
8573 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8574 mapping to segT enum values.
8575 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8576 if these are used or defined, if BFD_ASSEMBLER.
8577 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8578 subseg_new split into two functions.
8579 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8581 * as.h (volatile): Don't define if already defined.
8582 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8584 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8585 declare with format attribute for -Wformat checking.
8587 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8589 * app.c, config/tc-*.c: Don't include read.h, since it is already
8592 * These are based on patches from Minh Tran-le
8593 <mtranle@paris.intellicorp.com>.
8594 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8595 obj_format coffbfd and gas_target i386coff for target.
8596 (i[34]86-*-isc*): New host (uses sysv).
8597 * config/i386aix.mt: Removed (no longer used).
8598 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8600 (LDFLAGS): Added, defined as -shlib.
8601 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8602 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8603 (DOT_LABEL_PREFIX): Define.
8604 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8605 name rather than L0\001.
8606 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8608 * symbols.c, symbols.h (local_bss_counter): Removed.
8609 * write.c (write_object_file): bss no longer uses

8617 (size_section): Restored sanity check.
8618 (do_relocs_for): Base section address on s_paddr rather than
8619 computing it. Adjust a29k R_IHIHALF special case to account for
8620 section paddr (used to require paddr to be zero). If there are no
8621 reclos, set s_relptr to 0. Set relocation size in object_headers.
8622 (fill_section): Always set s_vaddr here, removing
8623 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8624 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8625 Set STYP_INFO for .comment.

8629 H_{SET,GET}_* macros.
8630 (do_linenos_for): Set lineno size in object_headers.
8631 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8632 set s_vaddr here. If string_byte_count remains 4, set it back to
8633 0, and only write strings out if there are some. Call
8634 fill_section before do_relocs_for and do_linenos_for.
8635 (obj_coff_section): Handle optional quoted second argument giving
8636 section characteristics.
8637 (obj_coff_bss): Added to handle .bss.
8638 (obj_coff_ident): Added to handle .ident (puts string in .comment

8641 (fixup_mdeps): Change to segment. Call frag_wane after
8643 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8644 adjustment (already happened only for common symbols, but this is
8646 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8647 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8658 (do_scrub_next_char): For \", return " not '.
8659 (symbol_chars): Now const.
8661 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8662 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8664 * config/obj-coff.h: Don't use #elif.
8666 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8667 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8693 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8694 using ZERO_BASED_SEGMENTS.
8695 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8696 never set segment address for SEG_E2 (.bss) and don't write out
8697 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8698 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8699 definitions, and don't merge tags with non-tags. Check for .bf
8700 rather than just checking whether the second character is b and
8701 the third character is f.
8702 (obj_coff_val): gcc can generate values which we don't handle
8703 correctly; discard information for now, since it only affects the
8704 debugging information.
8705 (tag_find_or_name): Don't insert tags in the symbol table.
8706 (yank_symbols): Don't merge labels.
8707 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8910 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
8911 so widening works consistently.
8913 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
8915 * version.c: Put conditional "const" before version_string, not

8918 * app.c (do_scrub_next_char): Need double-\ before `000' to show
8919 printed rep of null character.
8921 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)

8926 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8928 * Support for i386-sysv.
8929 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
8930 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
8931 be used to set them all to zero as was done before.
8932 (fill_section): segment addresses now set in write_object_file.
8933 (fill_section): Don't set STYP_NOLOAD for .bss section.
8934 (fixup_segment): 386 uses strange common symbol format.
8935 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for

8967 * tc-z8k.c: lots of bug fixes
8969 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8971 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8972 #elif, since it is not supported by old compilers.
8973 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8974 couple of expressions in tc-m68k.c.
8976 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8978 * read.c (cons): If NO_RELOC is defined, use it.
8980 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8982 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8984 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8985 local labels to start with a .) and set REGISTER_PREFIX to %.
8986 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

9004 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9005 sections starting from zero, rather than making them consecutive.
9006 This makes subsequent reloc calculations easier, esp if the object
9007 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9008 allocate lcomm in .data rather than in .bss. It seems that some
9009 tools can't cope with a non-zero sized bss before linkage.
9011 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9013 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

9032 * Makefile.in (install): if $(tooldir) exists, install as in
9035 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
9037 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9038 .word is < -32768 or > 32767. The -J flag causes the error to be
9039 ignored. This is to catch over-sized switches generated by gcc on
9040 systems which don't support the broken .word hack.
9041 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9042 write.c (fixup_segment): check for signed .word overflow if
9043 WARN_SIGNED_OVERFLOW_WORD.

9062 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
9064 * input-scrub.c (input_scrub_push): call input_file_begin, not
9066 messages.c (as_perror): print ": " between the passed in error and
9067 the strerror, like perror does.

9072 From Steve Chamberlain:
9073 Makefile.in: Handle m68*-*-coff*.
9074 read.c, read.h: add mult argument to s_space
9076 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
9077 Motorola and MIT syntax; gas can now assemble either type of
9079 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

9086 (fixup_segment) set fx_subsy to 0.
9087 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9089 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9092 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9094 * Makefile.in (LIBS): Include opcode library.

9119 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9121 * config/tc-m68k.c (init_table): Now const. Always include 68851
9122 data, so that "bc" is available to 68040 cache instructions.
9123 Added "tt0", "tt1", and 68ec030 variants.
9124 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9125 (enum _register): Added TT0, TT1.
9126 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9127 line number correctly in "internal error" messages. Don't print
9128 architecture-mismatch message for operand errors.
9130 From Colin Smith (colin@wrs.com):
9131 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
9132 than install_operand.

9153 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9154 has already been formatted (but may still contain %-characters).
9157 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9159 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9160 written with indirection on the last two operands, which can be
9161 either data or address registers. Added a new operand type 'r'
9162 which accepts either register type. Added '(' to notend stuff in
9163 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9210 being used with args swapped, causing occasional lossage when
9211 refilling buffers after an include file.

9388 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9390 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
9391 calc the base of relocs correctly.
9392 * tc-a29k.c (parse_operand): allow expressions to be in any section.
9394 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
9396 * as.c, write.c: use -K rather than -k for the broken word warning
9399 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
9401 * Makefile.in: do not print recursion lines.
9403 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9405 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
9407 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9409 * write.c (write_object_file): For b.out format, round up section
9410 start addresses to match required alignment.
9412 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9414 * Makefile.in (install): Install into $(tooldir)/bin, since that's
9415 where gcc looks for it.
9417 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
9419 * Makefile.in: Changed some lines to be less confusing for some
9422 * input-file.c: Conditionalize on _IOFBF, not VMS.
9424 * read.c, write.c: Change a series of ifdef/elif to
9425 ifdef/else/ifdef etc.
9427 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
9429 * symbols.c (fb_label_init): fix sizeof to memset.
9431 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
9433 * Makefile.in: install the man page.
9435 * Makefile.in: pass down MAKEINFO explicitly on info.
9437 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
9439 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9441 * flonum-const.c: renamed flonum-konst.c to stop dos name
9444 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
9446 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
9447 tc-m68k.h to te-sun3.h.
9449 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
9451 * configure.in: vxworks68 gets te-sun3.h.
9453 * expr.c: remove limitation that local_labels_dollar or
9454 local_labels_fb must be < 10.
9456 * symbols.c: remove local_labels_dollar, replace with a function
9457 interface for a sparse array. All users adjusted.
9459 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
9461 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9463 * doc/Makefile.in: commented out line for building as-all.texinfo.
9466 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
9468 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

9480 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
9482 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9485 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9487 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9489 * expr.c (operand): if can't work out what sort of operand it is,
9490 then look through FLT_CHARS for a hint.
9492 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9494 * Makefile.in, configure.in: removed traces of namesubdir,
9495 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9496 copyrights to '92, changed some from Cygnus to FSF.
9498 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9499 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9500 copyrights to '92, changed some from Cygnus to FSF.
9502 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9504 * expr.c: If an expression is single comma, then return with
9505 SEG_ABSENT rather than an error - since the sparc front end does
9506 really strange things with things like fbge,a
9508 * as.h: include bfd.h if using many sections
9509 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9510 local labels didn't work.
9511 * listing.c (list_symbol_table): don't core dump when there's no
9513 * write.c, write.h: call fix_new with the right number of args on
9515 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9518 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9520 * app.c: MRI compatibility - allow single quote to start a string.
9521 * as.c: fix typo recently introduced.
9522 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9523 * expr.c: Much rewriting, to accomodate MRI syntax for
9524 expressions. Also easier to read now.
9525 * listing.c: Put back defuns
9526 * read.c: modified to accept MRI syntax, put back listing pseudo
9527 ops so that an assembler built with NO_LISTING ignores list ops
9529 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9530 machine is a SPARC or a 29K.
9531 * config/obj-aout.c: added s_sect pseudo op
9532 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9533 fill in the timestamp.
9534 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9535 anymore, define all the relocs which the tc-<x> bit will use so we
9536 can translate from them to the coff types.
9537 * config/tc-a29k.c: reloc_type isn't ane enum any more
9538 * config/tc-m68k.c: Added NO_RELOC definition.
9540 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9542 * Makefile.in: put header files before C source for TAGS; remove
9543 references to non-existent syscalls.h.
9545 * read.c, write.c subsegs.c: back out the .bss changes.
9547 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9549 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9553 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9555 * symbols.c (local_label_name): symbols now start with ^A.
9557 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9558 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9559 generate these sections. .align: will use NOP_OPCODE or 0
9560 for padding. This is just for being nice to the
9563 * expr.c (operand): changed to generate local label "\001L0"
9564 starting with a ^A so that it is recognized as a local label.
9566 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9568 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9569 i/o opcodes - inb, inw, outb and outw. string manipulation with
9570 att syntax - scmp, slod, smov, ssca, ssto.
9572 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9573 to just after .file .
9575 In obj_crawl_symbol_chain() where it tries to put the external
9576 symbols apart, with the condition:
9577 (!S_IS_DEFINED(symbolP) &&
9578 !S_IS_DEBUG(symbolP) &&
9579 !SF_GET_STATICS(symbolP))
9580 it was moving too many symbols out. So I switch it back to the
9582 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9584 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9585 so that we don't use the F_RELFLG which make the linker complain
9586 that somebody has stripped the relocation info.
9588 Also, the AIX ld program require that the relocation table
9589 is sorted by r_vaddr like the standard ATT assembler does.
9591 [he also changed the sizeof(struct ...)'s into the coff
9592 style FOOSZ macros. I'm not sure this is right, but I can't
9593 remember why. xoxorich.]
9595 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9597 * Makefile.in, configure.in, doc: use the doc. Build it, install
9600 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9602 * read.c: white space and comments only.
9604 * configure.in: use the new atof-ns32.c for ns32k.
9606 * write.c: comment change only.
9608 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9609 aren't yet integrated.
9611 * tc-i860.[hc]: blew off the dust. Something must still be done
9612 about conflicting relocation types.
9614 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9617 * tc-i960.c, tc-sparc.c: white space and comments only.
9619 * tc-a29k.h: delete duplicate macro definition.
9621 * new file atof-ns32k.c copied from hack's last unreleased gas.
9623 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9625 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9628 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9629 ChangeLog's prior to this are sketchy at best. I have logs.
9630 They just aren't ChangeLogs.
9637 version-control: never
