987 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
989 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
990 it's better to use the one in libiberty.
992 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
994 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
995 change; it breaks the rs6000 support, and doesn't seem to be
998 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
1000 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

1006 rather than explicitly adding the frag address.
1007 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
1008 the end of the line numbers; this replaces the zero entry which
1009 used to be added by coff_add_linesym, removed Oct 7.
1010 (coff_adjust_section_syms): Ignore sections with no seginfo.
1012 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1014 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a

1016 instead in the -B options.
1017 (comparison): Revert yesterday's change.
1019 Tue Oct 11 16:48:11 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1021 * config/tc-sparc.c (tc_gen_reloc): For non-a.out relocations, if

1026 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
1027 for an embedded PIC switch expression, since the definition of
1028 S_IS_LOCAL was changed.
1030 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1032 * Makefile.in (comparison): When comparing as.new or gasp.new, try
1033 running the binary through sed to avoid differences due to

1036 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1038 ELF symbol size handling, based on code from Eric Youngdale:
1039 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an

1046 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
1048 (obj_elf_size): Deleted unused code. If size is non-reducible
1049 expression, allocate some storage for the sy_obj field and copy
1051 (elf_frob_symbol): New function. Computes sizes, calls
1052 ecoff_frob_symbol if appropriate.
1054 * write.c (fixup_segment): For i386 elf and coff (for now), don't
1055 add in value of symbol from another defined section of the file.

1080 * config/obj-vms.h (S_IS_LOCAL): fix obsolete flagseen[] reference.
1082 Wed Oct 5 11:49:26 1994 Ian Lance Taylor <ian@sanguine.cygnus.com>
1084 * config/obj-ecoff.c (obj_pseudo_table): Accept .esize and .etype

1101 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
1103 (diststuff): New target; builds DISTSTUFF.
1104 (realclean): Separate target, depend on clean and distclean, then
1106 * make-gas.com: Deleted.
1108 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
1109 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
1111 (i386_operand): Don't look up section symbol for
1113 (reloc): Always permit return of 8- and 16-bit relocation types.
1114 Add a space after "pc-relative" in the error message.
1115 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1116 BFD_RELOC_386_GOTOFF relocs.

1120 (TC_VALIDATE_FIX): New macro -- call it.
1121 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

1126 * write.h (struct fix): Added new bitfield fx_plt, for fixups
1127 referring to PLT entries.
1128 * write.c (fix_new_internal): Initialize fx_plt to zero.
1129 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
1130 Don't adjust fx_offset by frag address, since S_GET_VALUE now
1131 includes the frag address.
1132 (fixup_segment): Changed local var PCREL to type int, added PLT.
1133 If PC-relative fixup refers to a PLT entry for a symbol in the
1134 current section, don't reduce it.

1158 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1160 * configure.in: Set bfd_gas for all sparc targets in one place,
1161 instead of separately for each. Correctly handle user-supplied
1162 "--enable-bfd-gas" option.
1164 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1166 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
1169 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
1170 processing if add_symbol is undefined or in expr_section.

1172 constant-valued symbol, convert to O_symbol and re-reduce.
1173 (S_GET_VALUE): If symbol needs resolving, resolve it.
1174 (indent_level): No longer static.
1175 (print_symbol_value_1): Don't print frag address if it matches

1179 (print_expr_1): Fix whitespace before printing X_add_number.
1181 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1182 not symbol_new, for symbols holding expression values.
1183 * expr.h (make_expr_symbol): Move declaration here.
1184 * write.c (fix_new_exp): Handle O_add by creating an
1185 expression-valued symbol, and calling fix_new_exp recursively.
1186 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1187 undefined symbol and a constant, fold the constant into the fixup,
1188 and refer to the undefined symbol directly. Then process the
1189 fixup again from scratch.
1190 (write_object_file): Before calling adjust_reloc_syms, make a pass
1191 through the symbol list trying to resolve values.
1193 * write.c (print_fixup): New routine, for debugging.
1194 (write_relocs): Call bfd_install_relocation. Deleted various
1195 hacks for working around problems with bfd_perform_relocation.
1197 * Makefile.in (VERSION): Update to 2.4.90.
1199 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1201 * Makefile.in (gasp.o): Depends upon config.h.
1203 * config/tc-mips.c: Include subsegs.h.
1204 (md_apply_fix): If an unconditional b or bal overflows, and we are
1205 not assembling PIC code, replace it with a j or jal.
1207 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1208 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
1210 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1212 * write.c (write_relocs): Add file name and line number to
1213 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1214 RELOC_EXPANSION_POSSIBLE.
1216 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1218 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1219 here. Use them for deciding which PRINTF*LIKE macro definitions
1221 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1222 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1223 default definitions matching what we were doing before.
1224 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1225 always use the varargs form if not using stdarg. It's safe to
1226 always use vfprintf, because libiberty will provide it if the
1227 native system doesn't. Also, always make format be const.
1228 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
1230 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1243 (listing_newline): Check filename as well as line number when
1244 deciding whether to record it.
1245 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1246 false (if defined) as well as checking for reg_section.
1247 (listing_listing): Iterate fetching lines while line number is too
1248 low, and we haven't run off the end of the input file.
1250 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1252 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1254 * ecoff.c (ecoff_generate_asm_lineno): check if
1255 current_stabs_filename is NULL before strcmp.
1256 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
1259 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1261 * config/ho-*.h: Now-unused files deleted.
1263 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1264 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1265 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1266 zero. Don't call obj_frob_forward_symbol.
1267 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1268 X_add_number is zero.
1269 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1271 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1273 (strchr): Don't declare.
1274 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
1275 md_estimate_size_before_relax, md_ri_to_chars,
1276 md_create_short_jump, md_create_long_jump.
1277 (brtab_emit): Use data_section, not SEG_DATA.
1279 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1281 * config/vms-conf.h: new file, manually derived from conf.in.
1282 * config-gas.com: use it, and eliminate obsolete "host.h".
1284 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1286 * config/tc-ppc.c (ppc_current_block): New static variable.
1287 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
1288 ppc_current_block. Don't move around any stab symbol, just those
1290 (ppc_bs): Set ppc_current_block.
1291 (ppc_es): Clear ppc_current_block.
1292 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1293 from the csect of the enclosing block.
1295 * config/tc-mips.c (insns_since_cache_access): Remove.
1296 (append_insn): Remove setting of insns_since_cache_access, and
1297 special 4600 handling; it turns out not to be required.
1299 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1301 * config/tc-mips.c (md_shortopts): Remove E.
1302 (md_longopts): Add EB and EL.
1303 (md_parse_option): Handle -EB and -EL as separate options, rather
1304 than as a single -E option with an argument.
1306 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
1308 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
1309 involving global symbols too.
1311 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1313 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1315 * configure.in: Test for remove, not delete. Fix cross-assembler
1317 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1320 * read.c (pseudo_set, case O_symbol): If
1321 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1322 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1323 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1325 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1327 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1328 many others): new macros; values obtained from "DSTRECRDS.SDL".
1329 * config/obj-vms.h (various): use them.
1330 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1331 representation (only enum bitfields can avoid being bitstrings).
1332 (bitfield_suffix, setup_basic_type): new routines.
1333 (VMS_typedef_parse): use them. Now recognize bitfields of all
1334 integral types, not just type `int'. Caveat: the representation
1335 used for bitfields still does not work for objects placed in
1336 registers, and gcc's optimizer sometimes puts small structs there.
1338 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1340 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1341 bit from const_flag.
1342 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1343 (tc_frob_label): define this to call vms_check_for_special_label,
1344 and declare the latter.
1345 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1347 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1348 (vms_check_for_special_label): new routine (tc_frob_label).
1349 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1350 and `gcc2_compiled.' labels; they won't reach here any more.
1351 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1352 double', use `vax_g_doubles' flag to select type of double.
1353 (VMS_write_object_file) [traceback setup]: don't pass symbols
1354 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1355 and TBT_Routine_End functions.
1357 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
1359 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1360 S_GET_VALUE() to avoid many repeated function calls.
1361 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1362 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1363 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1364 be obsolete; gcc does it automatically for vms target. It's
1365 also misnamed, because it is for the "VAX C" run-time library,
1366 not the newer "DEC C" one which has much different startup code.]
1367 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1368 `S_GET_xxx(symbol) = new_value'.
1370 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1372 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1373 not &bfd_abs_section.
1375 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1377 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1379 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1381 * expr.c (expr): Don't reduce the difference of two symbols in the
1382 same frag if the symbols are not in normal sections.
1384 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1385 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1386 (obj_attach_unwind_info): Do not define. Not needed anymore.
1387 * config/tc-hppa.c: Delete whitespace at EOL.
1388 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1389 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1390 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1391 fixups, store 32bits of unwind information in the fx_addnumber
1393 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1394 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1395 pointer to 32 bits of unwind info.
1396 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1397 pointer to the dummy symbol; set the addend field to fx_addnumber.
1398 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1399 rather than &bfd_XXX_section.
1401 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1403 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1404 value by one; discard adjustments previously being made. From
1407 VMS- and Vax-related changes from Pat Rankin:
1408 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1409 * vmsconf.sh: no longer have make-gas.com echo text about needing
1410 to modify the gcc-vms driver when intending to use with gcc 1.x.
1411 * as.c (parse_options): suppress 'v' from std_short_options and
1412 eliminate VMS-specific conditional initialization;
1413 [default case]: check for '-v' if md_parse_options doesn't recognize
1415 [default case, #if VMS]: check for filename argument when '-v' seen;
1417 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1418 for O_big literal operands (double floats and long long ints);
1419 [VMS, md_shortopts]: add second colon after 'v';
1420 (md_parse_options) [VMS, case 'v']: check for argument, so
1421 caller can handle `-v' w/o arg.
1423 Tue Sep 13 16:45:08 1994 Steve Chamberlain (sac@jonny.cygnus.com)
1425 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET
1426 is defined, put the tx_offset into the r_offset.

2472 (control_regs): New pointer.
2473 (m68k_ip): Use control_regs instead of testing CPU every time.

2823 * config/obj-ecoff.c (ecoff_frob_file): Use bfd_ecoff_set_gp_value
2824 and bfd_ecoff_set_regmasks to set the GP value and the register
2825 masks, rather than using the now obsolete fake .reginfo section.
2827 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2829 * listing.c (list_symbol_table): Don't print register symbols as
2832 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
2833 underscores, since symbol_new will already have done it.
2834 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
2836 * as.c (main): If tc_init_after_args is defined, invoke it after
2837 all arguments have been processed.
2839 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
2840 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
2841 section instead of .text. Call create_target_segments.
2842 * read.c (demand_copy_string): No longer static.
2844 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2846 * config/tc-mips.c (append_insn): Permit branches to be switched
2847 with the preceding instruction even if .set nobopt has been seen.
2848 .set nobopt actually controls whether to bring up an instruction
2849 from the branch target, which gas does not currently support.
2851 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2853 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

2866 * config/tc-sparc.c (md_section_align): Always round up to
2867 multiple of alignment power specified in bfd target vector.
2869 * gasp.c: Include ctype.h.

2880 register mask, skip empty fill frags caused by enabling listing
2883 * config/ho-sysv.h: Include string.h.
2885 * doc/internals.texi: New (well, recently added) file. Just added
2886 info on as_warn and friends.

2890 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
2891 defaults for defined, private, and spnum fields for the
2892 $TEXT$ and $PRIVATE$ spaces. Do not clobber spnum. Do
2893 not reset the segment if just updating a space.
2894 (pa_spaces_begin): Set BFD section flags for all built-in
2897 Fri Apr 15 10:51:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

2902 address zero, insert a dummy line to compensate.
2904 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
2907 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2909 * expr.c (operand): Try to parse "0f" and "0b" sequences as
2910 floating point and binary numbers respectively; if it doesn't
2911 work, treat them as local labels.
2913 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
2914 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2916 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2918 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2919 source files from other directories into objects in the current
2920 directory, and specify PSECT attributes explicitly to linker.
2921 Also added missing label.
2922 * Makefile.in (stamp-mk.com): Reference new variable
2923 VMS_OTHER_OBJS for list of non-local object files, instead of

2935 * Makefile.in (de-stage1, de-stage2, de-stage3): Use rm -f.
2937 * config/tc-mips.h (DIFF_EXPR_OK): Define.
2938 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
2939 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
2940 argument, the reloc type.
2941 (load_register): Pass reloc type to macro_build for 'u'.
2942 (macro): Likewise. For M_LA_AB permit a difference expression
2943 when generating embedded PIC code between an arbitrary symbol and
2944 a symbol in the .text section.
2945 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
2946 BFD_RELOC_PCREL_LO16 to be emitted.

2954 * subsegs.c (subsegs_begin): Call memset with args in the correct
2956 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2957 to NULL instead of 0.
2959 Mon Apr 11 09:00:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2961 * config/tc-hppa.c (pa_procend): Handle case where label was
2962 defined after the .proc directive.
2964 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
2965 procend for a procedure without a name.

2986 (hppa_tc_symbol): Likewise.
2988 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2989 elf_tc_make_sections stuff. It was there to support PA braindamage
2990 which has been fixed, and in the case of elf_tc_make_sections is
2991 redundant with elf_tc_final_processing.
2993 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2995 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the
2998 Tue Apr 5 15:48:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3000 * config/tc-mips.c (mips_ip): For case 'o', when generating
3001 embedded PIC code, accept the difference between two local symbols
3003 (mips_force_relocation): Only force a reloc to be generated for a
3005 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
3006 value into the file if the fixup will not generate a reloc.
3008 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
3010 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
3011 don't spew remainder of input file in error message.
3012 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
3013 message with reloc type and try to process remainder of file.
3015 * doc/Makefile.in (install-info-as, install-info-gasp): New
3016 targets, now explicitly checking $(srcdir) for info files.
3017 (install-info): Depend on both of them; do nothing more.
3019 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
3021 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
3023 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3025 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
3026 flag rather than signedp field. Only permit extended range if
3027 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
3028 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
3030 * config/tc-ppc.c (ppc_size): New static variable.
3031 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
3032 (md_begin): If an instruction has a size specific flag set, only
3033 add it if we are assembling that size.
3035 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3037 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3038 cross section PC relative relocs right for COFF and ELF.
3040 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3042 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
3043 (OBJ_PROCESS_STAB): Don't define.
3045 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3047 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3048 the type of symbol set symbols which happen to be in the absolute
3049 or undefined section.
3051 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
3053 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3054 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3055 and -many (all architectures).
3057 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3059 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
3060 involving a function symbol which is not a plabel to zero.
3061 (md_apply_fix): Never pass a function symbol to field_adjust.
3063 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3065 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3066 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3068 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3069 branch with an instruction that uses $at, in case the branch is
3071 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3072 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3073 to make it pcrel_offset.
3074 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3075 reloc->address; another gruesome hack to get gas reloc handling to
3078 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3080 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3083 (emit_insn): New function.
3084 (md_assemble): Call it.
3085 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3087 (lituse_pending): New variable. Set by anything that generates a
3088 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3089 tested by code that might want to emit a LITUSE reloc.
3090 (emit_unaligned_io): New function. Currently calls md_assemble,
3091 but it should eventually be converted to generate the insn itself
3092 and call emit_insn directly.
3093 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3094 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3095 emit_bis_r): Likewise.
3096 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3097 (alpha_ip, label get_macro): Don't emit the final instruction if
3099 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3100 unaligned memory access macros.
3101 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3102 the value can't be resolved.
3104 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3106 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3107 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3108 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3110 (mips_force_relocation): New function.
3111 (md_apply_fix): Set fixP->fx_done appropriately.
3112 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

3120 * config/tc-mips.c (enum mips_pic_level): New enum.
3121 (mips_pic): Change from int to enum mips_pic_level. Change all
3122 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3123 (load_address): Handle EMBEDDED_PIC.
3124 (macro): Handle EMBEDDED_PIC in all PIC cases.
3125 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3126 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3127 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3128 works). Do not permit -G with SVR4_PIC.
3129 (s_abicalls): Warn if -G was used, and force -G 0.
3130 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3131 anything but a.out, not just for ELF. For ECOFF, don't generate a
3132 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3134 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3136 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3138 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3139 parameters to avoid losing when compiling with HP CC.
3140 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3142 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3144 * Makefile.in (config-stamp): If `defs' is defined, emit a
3145 preprocessor directive to create a macro named by this value into
3146 config.new; don't explicitly go for BFD_ASSEMBLER.
3147 * configure.in: Define `defs', not `BFDDEF'. Set it to
3148 MANY_SEGMENTS for any obj-coffbfd target.
3149 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3150 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3152 (LOCAL_LOADLIBES): Deleted.
3153 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3154 * config/m88kcoff.mt (TDEFINES): Ditto.
3155 * config/ebmon29k.mt: Deleted.
3156 * config/h8300hds.mt: Deleted.
3157 * config/ic960coff.mt: Deleted.
3158 * config/sparc.mt: Deleted.
3159 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3160 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3161 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3162 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

3180 bfd_set_symtab is called.
3181 (dump_section_relocs): Note whether a symbol is a section symbol
3183 (adjust_reloc_syms): For now, always supply an absolute symbol for
3184 fixups without symbols but not yet `done'. Use section_symbol to
3185 get the symbol, instead of going directly for abs_symbol.
3186 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3187 reloc is not a section symbol and is not in the symbol table.
3188 (set_symtab): New function, broken out from write_object_file.
3189 Counts symbol table instead of relying on an earlier count.
3190 (write_object_file): Call set_symtab, but do it after potentially
3191 invoking the *_frob_file macros. Don't bother counting symbols.
3192 Call symbol_remove, instead of expanding it in place. Moved the
3193 conditionalized `object_file_size' declaration down to
3194 conditionalized block where it's used. When using the absolute
3195 symbol for a fixup without a symbol, set sy_used_in_reloc.
3196 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3197 the correct symbol for the absolute section.
3199 * subsegs.c (section_symbol): Use symbol_new instead of
3200 symbol_make, since we may want it to go into the symbol table.
3201 Make the new symbol have internal linkage. If
3202 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3203 symbol with the newly created GAS symbol.
3204 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3205 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
3207 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
3209 * config/tc-sparc.c: Include subsegs.h.
3210 (in_signed_range): New function.
3212 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3213 (sparc_ip, label "immediate"): Reject constants for pcrel
3214 instructions only if the relocation type indicates a "call"
3215 instruction and the offset is within range of a "jmpl %g0". If
3216 it's not in range, use the absolute section symbol plus an offset.
3217 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3219 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3221 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3224 * configure.in: Eliminated all targets using obj-coff but not
3225 defining BFD_ASSEMBLER; I think all such targets that are
3226 supported will be matched by real CPU-OS combinations earlier in
3228 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3229 some comments about the dpx2 configuration, but left it disabled,
3230 since it couldn't be reached before.
3231 (target a29k-amd-ebmonold): Deleted.
3233 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3240 * config/tc-mips.c (mips_ip): Only accept overly large values for
3241 the 'j' operand if there are no further alternatives for this
3244 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3245 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3246 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3248 * config/tc-mips.c (mips_align): Take new argument, label, and use
3249 it instead of global insn_label.
3250 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3251 call to mips_emit_delay and pass it to mips_align.
3253 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3255 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3257 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3258 argument to a .callinfo directive. Don't loop forever on errors.
3260 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3261 use pre-defined registers as arguments.
3263 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3265 * write.c (write_object_file): Check both S_IS_LOCAL and
3266 S_IS_EXTERNAL when deciding whether to discard a symbol.
3268 * config-gas.com: Scan Makefile.in, not version.c, for current
3269 version number. Delete all versions of temp files when finished
3270 with them. Create config.h.

5010 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
5011 standard hpux include files to pick up various function decls.
5013 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

5046 of interest to the linker. ENTRY/EXIT relocations for SOM are
5047 an example of marker relocations.
5048 * write.c (write_relocs): Instead of assuming size of a relocation
5049 is 4 bytes, pick up the size from relocation itself.

5077 BFD_RELOC_MIPS_GPREL. Added new case a.
5078 (set_at, load_register, macro): Changed calls to macro_build to
5079 pass new argument for i, j and o cases.
5080 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
5081 special handling when generating SVR4 PIC code.

5418 for keeping or rejecting configurations still under development;
5419 default is to assume production environment, and reject configs
5420 still being worked on. Mark Elf configurations (except sparc and
5421 i386) as developmental. Deleted cases matching some generic names
5422 in favor of more specific names. (E.g., when we get Alpha

5439 through inclusion of tc-hppa.h. Delete all forward declarations
5440 for functions only used within tc-hppa.c, likewise for structures,
5441 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5442 conditional code in a few small places.

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

5536 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5538 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5539 ELF, since the ELF object format does not have these type of
5540 relocations. Change the abort into as as_bad and return
5541 BFD_RELOC_NONE to silence compiler warnings.
5542 (md_assemble): Keep track of the instruction size. Allow white
5543 space between the $ and the constant for compatibility with older

6507 * config/ho-sunos.h: remove some old function decls that conflict
6508 w/ ANSI, and which weren't needed anyway
6510 Wed Jul 28 16:34:55 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
6512 * config/obj-elf.h (obj_frob_symbol): Renamed from tc_frob_symbol,
6513 and disabled since it breaks Ian's new symbol-value code.

6553 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
6554 are also magic, and have special default flag settings.
6555 (obj_elf_frob_symbol): Since the return value from this function
6556 isn't used, don't bother calling obj_elf_write_symbol_p, since it
6557 doesn't accomplish anything else.

6569 undefined_section for the return value.
6571 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
6572 pseudo-op with a poc_handler field of NULL, ignore it and treat it
6573 as an instruction instead.

6577 * config/tc-h8500.c (md_begin): Use a local variable when

6589 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
6590 case to set obj_format=elf. Must go before i386-*-sysv* case that
6591 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
6592 *-*-solaris case, and move to before *-sysv* case that wants to
6593 set obj_format to coff.

6619 * Extensive changes to permit symbols to contain any expression
6620 type and to delay the computation of the expression until the
6621 value is actually needed. This permits setting symbols to values
6622 calculated based on object code size. Expressions were changed to
6623 no longer be in a section, to stop the overloading of segment and
6624 expression type that previously occurred.
6626 * as.c (big_section, pass1_section, diff_section, absent_section):
6628 (expr_section): Added (used for dummy symbols which hold

6712 (previous_section, previous_subsection): New vars.
6713 (obj_elf_section): Save current place in case DWARF code wants us
6714 to pop back to it. Handle unquoted section name as well as quoted
6715 section name. Don't crash on invalid strings.
6716 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

6828 sy_resolved and sy_resolving single bit fields.
6829 * symbols.c (symbol_new): Don't initialize sy_forward field.

7923 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
7924 the bottom (make expands variables in dependencies when the
7925 dependencies are read, not when they are used).
7927 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
7928 a29k .bss section; the mondfe program doesn't like it.

7949 source directory, if that's not the current directory.
7951 * configure.in (per-host): Accept MIPS host with BSD version
7953 (per-target): Classify i486 as i386. Use generic cpu_type instead

7972 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
7973 process relocs if there aren't any relocs to process. Avoids
7974 malloc/free bug on SCO too.
7976 * as.h: Move local include files below system include files, to
7977 avoid some redefinition complaints on some systems.
7978 (const, volatile): Don't need these conditionally defined if we
7979 use CONST and VOLATILE from ansidecl.h.
7980 (seg_name): Use CONST, not const.
7982 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
7984 * config/tc-mips.c: Reindented to GNU standards.
7986 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
7988 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
7989 (fixup_segment): Add a29k special case; the linker is not prepared
7990 to see a segment offset here.
7992 * app.c (do_scrub_next_char): Added new state, 10, modifying state

7995 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
7997 * Makefile.in: add dvi target; as-$(config).texinfo might live in
7998 srcdir, might be in objdir.

8018 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
8019 bignums, but don't emit error message.
8021 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
8023 * Makefile.in (targ-cpu.o): Depend on config.h.
8025 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
8027 * app.c (do_scrub_next_char): Added new state, 9, to avoid
8028 dropping a space immediately following an identifier.
8029 * expr.c, write.c: Rewrote assert expressions to not use multiple
8030 lines; I don't think that can be done portably.
8031 * config/tc-mips.c (macro): Use $AT if target register is zero in
8032 load instruction, which it can be for a floating point load.
8034 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

8045 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
8046 z8k-opc.h, not z8k.h.
8048 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
8051 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8053 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
8055 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
8057 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
8058 to be on a single line.
8060 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

8102 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
8103 (struct loc, struct proc, struct file): Moved to tc-mips.c within
8104 #ifndef OBJ_ECOFF block, since ECOFF uses different versions.

8106 prototypes for all static functions. Moved existing minimal
8107 debugging format support info #ifndef OBJ_ECOFF blocks.
8108 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
8109 does not support a non sign extended high 16 bits reloc. Adjusted
8110 all callers accordingly.
8111 (tc_get_register): Renamed from get_register, and made non-static.
8113 * config/mips-big.mt, config/mips-lit.mt: New files. Define

8156 * make-gas.com: Find obstack.obj if it's not in the current
8158 * read.c (s_ignore): Don't declare is_end_of_line. It's
8159 redundant, and triggers a VMS gcc compiler bug.
8161 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8162 current segment as an argument. (Ignored in all cases but VMS.)
8163 All callers and definitions changed.

8182 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
8183 Call elf_xstabs for .stabs and .xstabs operators.
8185 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
8187 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8190 * configure.in: mips-bsd configuration was missing format spec.
8193 * Makefile.in (Makefile): Depends on configure.in.
8195 * config/tc-mips.c (append_insn): Don't check for alignment of
8196 frag in memory; alignment of instructions in section is a separate
8199 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

8216 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8217 constants are accepted, but symbolic values are not. GCC will not
8218 generate the latter currently.
8220 * frags.c (frag_init): New function.
8221 (zero_address_frag, bss_address_frag): Now initialized at run
8223 * as.c (main): Call frag_init.

8267 (fixup_segment): Make sure common-section symbols get treated the
8268 same as undefined symbols.

8301 * read.c: Don't include ctype.h.
8302 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
8303 for now; should be machine-dependent.
8305 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
8306 targets, forcing BFD use.

8473 * config/tc-sparc.c (architecture_requested, warn_on_bump,
8474 md_relax_table): Use default zero initialization.
8475 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
8476 latter, instead of selecting with preprocessor conditionals.
8478 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8480 * configure.in: recognise all sparclite variants
8482 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

8485 accidentally changed to use subseg_change where it should have
8488 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8490 * expr.c (operand): If character other than comma or newline is a
8491 logical end-of-line character, use the newline case.
8492 From Eric Youngdale:
8493 (operand): Set X_add_number field for floating-point numbers.
8494 (operand): Treat zero byte as end-of-operand.
8496 * configure.in (per-target): Look for with_bfd_assembler option.
8497 For now, only accept "no", until the merge is done.
8499 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8500 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8501 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8502 * read.c: Finish conversion to S_* macros in the VMS only
8503 parts of the program. Add "const" modifier to hex_value.
8504 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
8506 * expr.c: Add "const" modifier to hex_value.
8507 * symbols.c: Finish conversion to S_* macros in the VMS only
8508 parts of the program. Add "const" modifier to
8509 md_[long,short]_jump_size. Remove declaration of const_flag
8510 (which will be declared in obj-vms.h).
8511 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8512 Fix arguments to VMS_write_object_file.
8513 * config-gas.com: New file. Script for VMS systems to set up the
8514 configuration to build gas for VMS, and create config.status.
8515 * make-gas.com: Redone to work with new scheme.
8516 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8518 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8519 will swap bytes if needed on a big endian system. Use throughout
8521 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8522 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8523 types of malformed stabs. Change parsing algorithm so that we are
8524 more certain of having all of the information that we need on hand.
8525 * obj-vms.c (final_forward_reference): New function, used to help
8526 resolve the data types of as many struct elements as possible
8527 when some part of the struct is not fully defined by the compiler.

8530 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8531 as symbols as well in the object file. Look for external functions
8532 that start with "__vt.", and turn them into variables, since the
8533 g++ compiler is incapable of doing this.
8534 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8536 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8537 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8538 have the name of the source file yet.
8539 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8541 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8543 * read.c (s_data): Always use "data_section", since it'll map to
8544 SEG_DATA or SEG_E1 if needed.
8545 (s_lcomm): Likewise with bss_section.
8546 (s_fill): Use memset, not bzero.
8548 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

8570 (big_section, reg_section, pass1_section, diff_section,
8571 absent_section, text_section, data_section, bss_section): If
8572 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8573 mapping to segT enum values.
8574 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8575 if these are used or defined, if BFD_ASSEMBLER.
8576 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8577 subseg_new split into two functions.
8578 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8580 * as.h (volatile): Don't define if already defined.
8581 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8583 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8584 declare with format attribute for -Wformat checking.
8586 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8588 * app.c, config/tc-*.c: Don't include read.h, since it is already
8591 * These are based on patches from Minh Tran-le
8592 <mtranle@paris.intellicorp.com>.
8593 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8594 obj_format coffbfd and gas_target i386coff for target.
8595 (i[34]86-*-isc*): New host (uses sysv).
8596 * config/i386aix.mt: Removed (no longer used).
8597 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8599 (LDFLAGS): Added, defined as -shlib.
8600 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8601 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8602 (DOT_LABEL_PREFIX): Define.
8603 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8604 name rather than L0\001.
8605 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8607 * symbols.c, symbols.h (local_bss_counter): Removed.
8608 * write.c (write_object_file): bss no longer uses

8616 (size_section): Restored sanity check.
8617 (do_relocs_for): Base section address on s_paddr rather than
8618 computing it. Adjust a29k R_IHIHALF special case to account for
8619 section paddr (used to require paddr to be zero). If there are no
8620 reclos, set s_relptr to 0. Set relocation size in object_headers.
8621 (fill_section): Always set s_vaddr here, removing
8622 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8623 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8624 Set STYP_INFO for .comment.

8628 H_{SET,GET}_* macros.
8629 (do_linenos_for): Set lineno size in object_headers.
8630 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8631 set s_vaddr here. If string_byte_count remains 4, set it back to
8632 0, and only write strings out if there are some. Call
8633 fill_section before do_relocs_for and do_linenos_for.
8634 (obj_coff_section): Handle optional quoted second argument giving
8635 section characteristics.
8636 (obj_coff_bss): Added to handle .bss.
8637 (obj_coff_ident): Added to handle .ident (puts string in .comment

8640 (fixup_mdeps): Change to segment. Call frag_wane after
8642 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8643 adjustment (already happened only for common symbols, but this is
8645 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

8657 (do_scrub_next_char): For \", return " not '.
8658 (symbol_chars): Now const.
8660 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8661 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8663 * config/obj-coff.h: Don't use #elif.
8665 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8666 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8692 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8693 using ZERO_BASED_SEGMENTS.
8694 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8695 never set segment address for SEG_E2 (.bss) and don't write out
8696 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8697 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8698 definitions, and don't merge tags with non-tags. Check for .bf
8699 rather than just checking whether the second character is b and
8700 the third character is f.
8701 (obj_coff_val): gcc can generate values which we don't handle
8702 correctly; discard information for now, since it only affects the
8703 debugging information.
8704 (tag_find_or_name): Don't insert tags in the symbol table.
8705 (yank_symbols): Don't merge labels.
8706 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8909 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
8910 so widening works consistently.
8912 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
8914 * version.c: Put conditional "const" before version_string, not

8917 * app.c (do_scrub_next_char): Need double-\ before `000' to show
8918 printed rep of null character.
8920 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)

8925 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
8927 * Support for i386-sysv.
8928 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
8929 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
8930 be used to set them all to zero as was done before.
8931 (fill_section): segment addresses now set in write_object_file.
8932 (fill_section): Don't set STYP_NOLOAD for .bss section.
8933 (fixup_segment): 386 uses strange common symbol format.

8966 * tc-z8k.c: lots of bug fixes
8968 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8970 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8971 #elif, since it is not supported by old compilers.
8972 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8973 couple of expressions in tc-m68k.c.
8975 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8977 * read.c (cons): If NO_RELOC is defined, use it.
8979 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8981 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8983 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8984 local labels to start with a .) and set REGISTER_PREFIX to %.
8985 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

9003 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
9004 sections starting from zero, rather than making them consecutive.
9005 This makes subsequent reloc calculations easier, esp if the object
9006 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
9007 allocate lcomm in .data rather than in .bss. It seems that some
9008 tools can't cope with a non-zero sized bss before linkage.
9010 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9012 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

9031 * Makefile.in (install): if $(tooldir) exists, install as in
9034 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
9036 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9037 .word is < -32768 or > 32767. The -J flag causes the error to be
9038 ignored. This is to catch over-sized switches generated by gcc on
9039 systems which don't support the broken .word hack.
9040 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9041 write.c (fixup_segment): check for signed .word overflow if
9042 WARN_SIGNED_OVERFLOW_WORD.

9061 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
9063 * input-scrub.c (input_scrub_push): call input_file_begin, not
9065 messages.c (as_perror): print ": " between the passed in error and
9066 the strerror, like perror does.

9071 From Steve Chamberlain:
9072 Makefile.in: Handle m68*-*-coff*.
9073 read.c, read.h: add mult argument to s_space
9075 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
9076 Motorola and MIT syntax; gas can now assemble either type of
9078 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

9085 (fixup_segment) set fx_subsy to 0.
9086 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9088 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9091 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9093 * Makefile.in (LIBS): Include opcode library.

9118 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9120 * config/tc-m68k.c (init_table): Now const. Always include 68851
9121 data, so that "bc" is available to 68040 cache instructions.
9122 Added "tt0", "tt1", and 68ec030 variants.
9123 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9124 (enum _register): Added TT0, TT1.
9125 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9126 line number correctly in "internal error" messages. Don't print
9127 architecture-mismatch message for operand errors.
9129 From Colin Smith (colin@wrs.com):
9130 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
9131 than install_operand.

9152 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9153 has already been formatted (but may still contain %-characters).
9156 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9158 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9159 written with indirection on the last two operands, which can be
9160 either data or address registers. Added a new operand type 'r'
9161 which accepts either register type. Added '(' to notend stuff in
9162 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9181 their not having symbols associated.
9183 * tc-i960.c (norelax, instrument_branches): Default initializer is
9185 (linkrelax): Delete variable definition.

9209 being used with args swapped, causing occasional lossage when
9210 refilling buffers after an include file.

9333 * write.c (write_object_file): various changes to handle data in
9334 the BSS segment in much the same was as stuff in the DATA segment.

9387 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9389 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
9390 calc the base of relocs correctly.
9391 * tc-a29k.c (parse_operand): allow expressions to be in any section.
9393 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
9395 * as.c, write.c: use -K rather than -k for the broken word warning
9398 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
9400 * Makefile.in: do not print recursion lines.
9402 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)

9406 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9408 * write.c (write_object_file): For b.out format, round up section
9409 start addresses to match required alignment.
9411 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9413 * Makefile.in (install): Install into $(tooldir)/bin, since that's
9414 where gcc looks for it.
9416 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
9418 * Makefile.in: Changed some lines to be less confusing for some
9421 * input-file.c: Conditionalize on _IOFBF, not VMS.
9423 * read.c, write.c: Change a series of ifdef/elif to
9424 ifdef/else/ifdef etc.
9426 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
9428 * symbols.c (fb_label_init): fix sizeof to memset.
9430 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
9432 * Makefile.in: install the man page.
9434 * Makefile.in: pass down MAKEINFO explicitly on info.
9436 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
9438 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9440 * flonum-const.c: renamed flonum-konst.c to stop dos name
9443 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
9445 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
9446 tc-m68k.h to te-sun3.h.
9448 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
9450 * configure.in: vxworks68 gets te-sun3.h.
9452 * expr.c: remove limitation that local_labels_dollar or
9453 local_labels_fb must be < 10.
9455 * symbols.c: remove local_labels_dollar, replace with a function
9456 interface for a sparse array. All users adjusted.
9458 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
9460 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9462 * doc/Makefile.in: commented out line for building as-all.texinfo.
9465 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
9467 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

9479 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
9481 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9484 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9486 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9488 * expr.c (operand): if can't work out what sort of operand it is,
9489 then look through FLT_CHARS for a hint.
9491 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9493 * Makefile.in, configure.in: removed traces of namesubdir,
9494 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9495 copyrights to '92, changed some from Cygnus to FSF.
9497 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9498 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9499 copyrights to '92, changed some from Cygnus to FSF.
9501 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9503 * expr.c: If an expression is single comma, then return with
9504 SEG_ABSENT rather than an error - since the sparc front end does
9505 really strange things with things like fbge,a
9507 * as.h: include bfd.h if using many sections
9508 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9509 local labels didn't work.
9510 * listing.c (list_symbol_table): don't core dump when there's no
9512 * write.c, write.h: call fix_new with the right number of args on
9514 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9517 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9519 * app.c: MRI compatibility - allow single quote to start a string.
9520 * as.c: fix typo recently introduced.
9521 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9522 * expr.c: Much rewriting, to accomodate MRI syntax for
9523 expressions. Also easier to read now.
9524 * listing.c: Put back defuns
9525 * read.c: modified to accept MRI syntax, put back listing pseudo
9526 ops so that an assembler built with NO_LISTING ignores list ops
9528 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9529 machine is a SPARC or a 29K.
9530 * config/obj-aout.c: added s_sect pseudo op
9531 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9532 fill in the timestamp.
9533 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9534 anymore, define all the relocs which the tc-<x> bit will use so we
9535 can translate from them to the coff types.
9536 * config/tc-a29k.c: reloc_type isn't ane enum any more
9537 * config/tc-m68k.c: Added NO_RELOC definition.
9539 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9541 * Makefile.in: put header files before C source for TAGS; remove
9542 references to non-existent syscalls.h.
9544 * read.c, write.c subsegs.c: back out the .bss changes.
9546 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9548 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9552 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9554 * symbols.c (local_label_name): symbols now start with ^A.
9556 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9557 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9558 generate these sections. .align: will use NOP_OPCODE or 0
9559 for padding. This is just for being nice to the
9562 * expr.c (operand): changed to generate local label "\001L0"
9563 starting with a ^A so that it is recognized as a local label.
9565 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9567 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9568 i/o opcodes - inb, inw, outb and outw. string manipulation with
9569 att syntax - scmp, slod, smov, ssca, ssto.
9571 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9572 to just after .file .
9574 In obj_crawl_symbol_chain() where it tries to put the external
9575 symbols apart, with the condition:
9576 (!S_IS_DEFINED(symbolP) &&
9577 !S_IS_DEBUG(symbolP) &&
9578 !SF_GET_STATICS(symbolP))
9579 it was moving too many symbols out. So I switch it back to the
9581 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9583 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9584 so that we don't use the F_RELFLG which make the linker complain
9585 that somebody has stripped the relocation info.
9587 Also, the AIX ld program require that the relocation table
9588 is sorted by r_vaddr like the standard ATT assembler does.
9590 [he also changed the sizeof(struct ...)'s into the coff
9591 style FOOSZ macros. I'm not sure this is right, but I can't
9592 remember why. xoxorich.]
9594 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9596 * Makefile.in, configure.in, doc: use the doc. Build it, install
9599 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9601 * read.c: white space and comments only.
9603 * configure.in: use the new atof-ns32.c for ns32k.
9605 * write.c: comment change only.
9607 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9608 aren't yet integrated.
9610 * tc-i860.[hc]: blew off the dust. Something must still be done
9611 about conflicting relocation types.
9613 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9616 * tc-i960.c, tc-sparc.c: white space and comments only.
9618 * tc-a29k.h: delete duplicate macro definition.
9620 * new file atof-ns32k.c copied from hack's last unreleased gas.
9622 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9624 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9627 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9628 ChangeLog's prior to this are sketchy at best. I have logs.
9629 They just aren't ChangeLogs.
9636 version-control: never
