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

998 * Makefile.in (comparison): When comparing as.new or gasp.new, try
999 running the binary through sed to avoid differences due to
1000 "stage1" or "stage2" having been written into the binary.
1002 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1004 ELF symbol size handling, based on code from Eric Youngdale:
1005 * config/obj-elf.h (OBJ_SYMFIELD_TYPE): New macro. Adds an

1012 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.
1014 (obj_elf_size): Deleted unused code. If size is non-reducible
1015 expression, allocate some storage for the sy_obj field and copy
1017 (elf_frob_symbol): New function. Computes sizes, calls
1018 ecoff_frob_symbol if appropriate.
1020 * write.c (fixup_segment): For i386 elf and coff (for now), don't
1021 add in value of symbol from another defined section of the file.

1069 (diststuff): New target; builds DISTSTUFF.
1070 (realclean): Separate target, depend on clean and distclean, then
1072 * make-gas.com: Deleted.

1080 Add a space after "pc-relative" in the error message.
1081 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1082 BFD_RELOC_386_GOTOFF relocs.

1086 (TC_VALIDATE_FIX): New macro -- call it.
1087 (NOP_OPCODE): Cast to `char' to avoid compiler warnings.

1093 referring to PLT entries.
1094 * write.c (fix_new_internal): Initialize fx_plt to zero.
1095 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
1096 Don't adjust fx_offset by frag address, since S_GET_VALUE now
1097 includes the frag address.
1098 (fixup_segment): Changed local var PCREL to type int, added PLT.
1099 If PC-relative fixup refers to a PLT entry for a symbol in the
1100 current section, don't reduce it.

1122 Show fx_r_type and fx_addsy fields.
1124 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1126 * configure.in: Set bfd_gas for all sparc targets in one place,
1127 instead of separately for each. Correctly handle user-supplied
1128 "--enable-bfd-gas" option.
1130 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1132 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
1135 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
1136 processing if add_symbol is undefined or in expr_section.

1138 constant-valued symbol, convert to O_symbol and re-reduce.
1139 (S_GET_VALUE): If symbol needs resolving, resolve it.
1140 (indent_level): No longer static.
1141 (print_symbol_value_1): Don't print frag address if it matches

1145 (print_expr_1): Fix whitespace before printing X_add_number.
1147 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1148 not symbol_new, for symbols holding expression values.
1149 * expr.h (make_expr_symbol): Move declaration here.
1150 * write.c (fix_new_exp): Handle O_add by creating an
1151 expression-valued symbol, and calling fix_new_exp recursively.
1152 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1153 undefined symbol and a constant, fold the constant into the fixup,
1154 and refer to the undefined symbol directly. Then process the
1155 fixup again from scratch.
1156 (write_object_file): Before calling adjust_reloc_syms, make a pass
1157 through the symbol list trying to resolve values.
1159 * write.c (print_fixup): New routine, for debugging.
1160 (write_relocs): Call bfd_install_relocation. Deleted various
1161 hacks for working around problems with bfd_perform_relocation.
1163 * Makefile.in (VERSION): Update to 2.4.90.
1165 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1167 * Makefile.in (gasp.o): Depends upon config.h.
1169 * config/tc-mips.c: Include subsegs.h.
1170 (md_apply_fix): If an unconditional b or bal overflows, and we are
1171 not assembling PIC code, replace it with a j or jal.
1173 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
1174 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
1176 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1178 * write.c (write_relocs): Add file name and line number to
1179 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1180 RELOC_EXPANSION_POSSIBLE.
1182 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1184 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1185 here. Use them for deciding which PRINTF*LIKE macro definitions
1187 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
1188 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1189 default definitions matching what we were doing before.
1190 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1191 always use the varargs form if not using stdarg. It's safe to
1192 always use vfprintf, because libiberty will provide it if the
1193 native system doesn't. Also, always make format be const.
1194 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
1196 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1209 (listing_newline): Check filename as well as line number when
1210 deciding whether to record it.
1211 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1212 false (if defined) as well as checking for reg_section.
1213 (listing_listing): Iterate fetching lines while line number is too
1214 low, and we haven't run off the end of the input file.
1216 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1218 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1220 * ecoff.c (ecoff_generate_asm_lineno): check if
1221 current_stabs_filename is NULL before strcmp.
1222 * read.c (read_a_source_file): fix a bug in generate_asm_lineno
1225 Wed Sep 21 18:17:35 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1227 * config/ho-*.h: Now-unused files deleted.
1229 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1230 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1231 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1232 zero. Don't call obj_frob_forward_symbol.
1233 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1234 X_add_number is zero.
1235 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1237 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1239 (strchr): Don't declare.
1240 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
1241 md_estimate_size_before_relax, md_ri_to_chars,
1242 md_create_short_jump, md_create_long_jump.
1243 (brtab_emit): Use data_section, not SEG_DATA.
1245 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1247 * config/vms-conf.h: new file, manually derived from conf.in.
1248 * config-gas.com: use it, and eliminate obsolete "host.h".

1252 * config/tc-ppc.c (ppc_current_block): New static variable.
1253 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to
1254 ppc_current_block. Don't move around any stab symbol, just those
1256 (ppc_bs): Set ppc_current_block.
1257 (ppc_es): Clear ppc_current_block.
1258 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1259 from the csect of the enclosing block.
1261 * config/tc-mips.c (insns_since_cache_access): Remove.
1262 (append_insn): Remove setting of insns_since_cache_access, and
1263 special 4600 handling; it turns out not to be required.
1265 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1267 * config/tc-mips.c (md_shortopts): Remove E.
1268 (md_longopts): Add EB and EL.
1269 (md_parse_option): Handle -EB and -EL as separate options, rather
1270 than as a single -E option with an argument.
1272 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
1274 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
1275 involving global symbols too.
1277 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1279 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1281 * configure.in: Test for remove, not delete. Fix cross-assembler
1283 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1286 * read.c (pseudo_set, case O_symbol): If
1287 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1288 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1289 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
1291 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
1293 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1294 many others): new macros; values obtained from "DSTRECRDS.SDL".
1295 * config/obj-vms.h (various): use them.
1296 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1297 representation (only enum bitfields can avoid being bitstrings).
1298 (bitfield_suffix, setup_basic_type): new routines.
1299 (VMS_typedef_parse): use them. Now recognize bitfields of all
1300 integral types, not just type `int'. Caveat: the representation
1301 used for bitfields still does not work for objects placed in
1302 registers, and gcc's optimizer sometimes puts small structs there.
1304 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1306 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1307 bit from const_flag.
1308 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1309 (tc_frob_label): define this to call vms_check_for_special_label,
1310 and declare the latter.
1311 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1313 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1314 (vms_check_for_special_label): new routine (tc_frob_label).
1315 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1316 and `gcc2_compiled.' labels; they won't reach here any more.
1317 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1318 double', use `vax_g_doubles' flag to select type of double.
1319 (VMS_write_object_file) [traceback setup]: don't pass symbols
1320 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1321 and TBT_Routine_End functions.

1325 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1326 S_GET_VALUE() to avoid many repeated function calls.
1327 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1328 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1329 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1330 be obsolete; gcc does it automatically for vms target. It's
1331 also misnamed, because it is for the "VAX C" run-time library,
1332 not the newer "DEC C" one which has much different startup code.]
1333 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1334 `S_GET_xxx(symbol) = new_value'.
1336 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1338 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1339 not &bfd_abs_section.
1341 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1343 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1345 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1347 * expr.c (expr): Don't reduce the difference of two symbols in the
1348 same frag if the symbols are not in normal sections.
1350 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1351 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1352 (obj_attach_unwind_info): Do not define. Not needed anymore.
1353 * config/tc-hppa.c: Delete whitespace at EOL.
1354 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1355 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1356 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1357 fixups, store 32bits of unwind information in the fx_addnumber
1359 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1360 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1361 pointer to 32 bits of unwind info.
1362 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1363 pointer to the dummy symbol; set the addend field to fx_addnumber.
1364 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1365 rather than &bfd_XXX_section.
1367 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1369 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1370 value by one; discard adjustments previously being made. From
1373 VMS- and Vax-related changes from Pat Rankin:
1374 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1375 * vmsconf.sh: no longer have make-gas.com echo text about needing
1376 to modify the gcc-vms driver when intending to use with gcc 1.x.
1377 * as.c (parse_options): suppress 'v' from std_short_options and
1378 eliminate VMS-specific conditional initialization;
1379 [default case]: check for '-v' if md_parse_options doesn't recognize
1381 [default case, #if VMS]: check for filename argument when '-v' seen;
1383 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1384 for O_big literal operands (double floats and long long ints);
1385 [VMS, md_shortopts]: add second colon after 'v';
1386 (md_parse_options) [VMS, case 'v']: check for argument, so
1387 caller can handle `-v' w/o arg.

1391 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET
1392 is defined, put the tx_offset into the r_offset.
1393 * config/tc-sh.c (line_comment_chars): Add #
1394 (tc_reloc_mangle): Deleted.
1395 * config/tc-sh.h (TC_KEEP_FX_OFFSET): Define.

1426 * as.h (EXIT_SUCCESS, EXIT_FAILURE): Moved here.
1427 * as.c: ...from here.
1428 (parse_args): Use them always.
1429 (main): Use exit rather than return.

2364 * Makefile.in (check): Delete as.new dependency, so that
2365 regression test doesn't trigger an assembler build.
2367 Tue Jun 7 13:33:18 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2369 * Makefile.in (mostlyclean, realclean): New targets.

2383 * read.c (emit_expr): Use memset to zero out memory, rather than
2384 going through md_number_to_chars. This permits handling symbolic
2385 arguments when the size is larger than sizeof (valueT), if
2386 TC_CONS_FIX_NEW is prepared to handle the case (as it is on MIPS).
2388 Fri Jun 3 12:50:13 1994 David J. MacKenzie (djm@rtl.cygnus.com)

2416 md_parse_option. Remove md_parse_long_option.
2417 * config/tc-ns32k.c: Rename `struct option' to `struct ns32k_option'.
2418 * config/tc-i386.h: Don't define md_parse_option.

2438 (control_regs): New pointer.
2439 (m68k_ip): Use control_regs instead of testing CPU every time.
2440 Use last_movec_reg too. In error messages, handle 68060, and
2441 print 68060 for mfloat, too.
2442 (m68k_init_after_args): Handle "68060". Use m68040up for making
2443 m68851 choice. Set control_regs.

2448 [DIFF_EXPR_OK]: Do conversion to pc-relative for difference, even
2449 if pcrel is already set.
2451 * read.c (potable): Add this_gcc_requires_the_gnu_assembler in all
2452 lower-case, in case we're ignoring case of opcodes in the input

2458 * config/tc-alpha.c (machine): New variable.
2459 (load_insn): New macro.
2460 (load_insn_table): New function.
2461 (md_begin): Call load_insn_table, once for basic instructions and
2462 once for appropriate PAL instruction table.

2485 * config/obj-vms.c: Replaced unchecked uses of malloc with
2488 * listing.c (list_symbol_table): Only test BFD64, not
2491 * config/obj-coff.c (fixup_segment) [BFD_ASSEMBLER]
2492 [DIFF_EXPR_OK]: Don't check pcrel, just convert it.
2494 * config/obj-vms.c: Removed lots of extra semicolons after
2495 compound statements.
2496 (strchr): Don't declare here.
2498 * config/ho-vax.h (realloc): Declare.

2511 VMS debugger now recognizes `long long' variables correctly.
2512 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
2513 for gcc2's predefined types "long double" (same as double, as
2514 per gcc's current state), "long long int", "long long unsigned
2515 int", and final `otherwise' case (to avoid uninitialized type
2516 and size fields). [caveat: predefined types "complex int",
2517 "complex float", "complex double", and "complex long double" are
2520 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
2521 of 0, because the latter indicates success rather than failure
2522 when passed to `exit' or return from `main' compiled by gcc2.

2525 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.
2526 (VMS_typedef_parse): eliminate redundant if-then-else when
2527 allocating new symbol entry and linking it to VMS_Symbol_type_list.
2529 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
2531 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret

2756 Define as macros instead of enumerators, since the Apollo compiler
2757 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
2759 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
2760 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
2761 R_DIR16, and R_DIR32 relocs.
2762 * config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
2763 Use Apollo versions.

2813 with the preceding instruction even if .set nobopt has been seen.
2814 .set nobopt actually controls whether to bring up an instruction
2815 from the branch target, which gas does not currently support.
2817 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2819 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

2906 argument, the reloc type.
2907 (load_register): Pass reloc type to macro_build for 'u'.
2908 (macro): Likewise. For M_LA_AB permit a difference expression
2909 when generating embedded PIC code between an arbitrary symbol and
2910 a symbol in the .text section.
2911 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and

2952 (hppa_tc_symbol): Likewise.
2954 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2955 elf_tc_make_sections stuff. It was there to support PA braindamage
2956 which has been fixed, and in the case of elf_tc_make_sections is
2957 redundant with elf_tc_final_processing.
2959 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2961 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

2977 don't spew remainder of input file in error message.
2978 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2979 message with reloc type and try to process remainder of file.
2981 * doc/Makefile.in (install-info-as, install-info-gasp): New
2982 targets, now explicitly checking $(srcdir) for info files.
2983 (install-info): Depend on both of them; do nothing more.

2987 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
2989 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2991 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2992 flag rather than signedp field. Only permit extended range if
2993 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2994 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2996 * config/tc-ppc.c (ppc_size): New static variable.
2997 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2998 (md_begin): If an instruction has a size specific flag set, only
2999 add it if we are assembling that size.
3001 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3003 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
3004 cross section PC relative relocs right for COFF and ELF.
3006 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3008 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
3009 (OBJ_PROCESS_STAB): Don't define.

3013 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
3014 the type of symbol set symbols which happen to be in the absolute
3015 or undefined section.
3017 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
3019 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
3020 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
3021 and -many (all architectures).
3023 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3025 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
3026 involving a function symbol which is not a plabel to zero.
3027 (md_apply_fix): Never pass a function symbol to field_adjust.
3029 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3031 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3032 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3034 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3035 branch with an instruction that uses $at, in case the branch is
3037 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3038 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3039 to make it pcrel_offset.
3040 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3041 reloc->address; another gruesome hack to get gas reloc handling to
3044 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3046 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3049 (emit_insn): New function.
3050 (md_assemble): Call it.
3051 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3053 (lituse_pending): New variable. Set by anything that generates a
3054 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3055 tested by code that might want to emit a LITUSE reloc.
3056 (emit_unaligned_io): New function. Currently calls md_assemble,
3057 but it should eventually be converted to generate the insn itself
3058 and call emit_insn directly.
3059 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3060 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3061 emit_bis_r): Likewise.
3062 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3063 (alpha_ip, label get_macro): Don't emit the final instruction if
3065 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3066 unaligned memory access macros.
3067 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3068 the value can't be resolved.
3070 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3072 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3073 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3074 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3076 (mips_force_relocation): New function.
3077 (md_apply_fix): Set fixP->fx_done appropriately.
3078 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

3086 * config/tc-mips.c (enum mips_pic_level): New enum.
3087 (mips_pic): Change from int to enum mips_pic_level. Change all
3088 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3089 (load_address): Handle EMBEDDED_PIC.
3090 (macro): Handle EMBEDDED_PIC in all PIC cases.
3091 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3092 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3093 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3094 works). Do not permit -G with SVR4_PIC.
3095 (s_abicalls): Warn if -G was used, and force -G 0.
3096 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3097 anything but a.out, not just for ELF. For ECOFF, don't generate a
3098 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3100 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3102 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3104 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3105 parameters to avoid losing when compiling with HP CC.
3106 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3108 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3110 * Makefile.in (config-stamp): If `defs' is defined, emit a
3111 preprocessor directive to create a macro named by this value into
3112 config.new; don't explicitly go for BFD_ASSEMBLER.
3113 * configure.in: Define `defs', not `BFDDEF'. Set it to
3114 MANY_SEGMENTS for any obj-coffbfd target.
3115 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3116 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3118 (LOCAL_LOADLIBES): Deleted.
3119 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3120 * config/m88kcoff.mt (TDEFINES): Ditto.
3121 * config/ebmon29k.mt: Deleted.
3122 * config/h8300hds.mt: Deleted.
3123 * config/ic960coff.mt: Deleted.
3124 * config/sparc.mt: Deleted.
3125 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3126 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3127 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3128 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

3146 bfd_set_symtab is called.
3147 (dump_section_relocs): Note whether a symbol is a section symbol
3149 (adjust_reloc_syms): For now, always supply an absolute symbol for
3150 fixups without symbols but not yet `done'. Use section_symbol to
3151 get the symbol, instead of going directly for abs_symbol.
3152 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3153 reloc is not a section symbol and is not in the symbol table.
3154 (set_symtab): New function, broken out from write_object_file.
3155 Counts symbol table instead of relying on an earlier count.
3156 (write_object_file): Call set_symtab, but do it after potentially
3157 invoking the *_frob_file macros. Don't bother counting symbols.
3158 Call symbol_remove, instead of expanding it in place. Moved the
3159 conditionalized `object_file_size' declaration down to
3160 conditionalized block where it's used. When using the absolute
3161 symbol for a fixup without a symbol, set sy_used_in_reloc.
3162 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3163 the correct symbol for the absolute section.
3165 * subsegs.c (section_symbol): Use symbol_new instead of
3166 symbol_make, since we may want it to go into the symbol table.
3167 Make the new symbol have internal linkage. If
3168 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3169 symbol with the newly created GAS symbol.
3170 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3171 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
3173 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
3175 * config/tc-sparc.c: Include subsegs.h.
3176 (in_signed_range): New function.
3178 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3179 (sparc_ip, label "immediate"): Reject constants for pcrel
3180 instructions only if the relocation type indicates a "call"
3181 instruction and the offset is within range of a "jmpl %g0". If
3182 it's not in range, use the absolute section symbol plus an offset.
3183 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3185 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3187 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3190 * configure.in: Eliminated all targets using obj-coff but not
3191 defining BFD_ASSEMBLER; I think all such targets that are
3192 supported will be matched by real CPU-OS combinations earlier in
3194 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3195 some comments about the dpx2 configuration, but left it disabled,
3196 since it couldn't be reached before.
3197 (target a29k-amd-ebmonold): Deleted.
3199 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3206 * config/tc-mips.c (mips_ip): Only accept overly large values for
3207 the 'j' operand if there are no further alternatives for this
3210 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3211 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3212 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3214 * config/tc-mips.c (mips_align): Take new argument, label, and use
3215 it instead of global insn_label.
3216 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3217 call to mips_emit_delay and pass it to mips_align.
3219 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3221 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3223 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3224 argument to a .callinfo directive. Don't loop forever on errors.
3226 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3227 use pre-defined registers as arguments.

3231 * write.c (write_object_file): Check both S_IS_LOCAL and
3232 S_IS_EXTERNAL when deciding whether to discard a symbol.
3234 * config-gas.com: Scan Makefile.in, not version.c, for current
3235 version number. Delete all versions of temp files when finished
3236 with them. Create config.h.
3238 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
3239 values to reduce number of lookups with S_GET_VALUE. Skip debug
3240 symbols to avoid "a really nasty bug". (From Holger Teutsch,
3241 holger@botbso.rhein-main.de.)
3242 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
3243 field. (Also from Holger Teutsch.) Watch for a would-be register
3244 mask that spans frags.
3246 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
3247 this_base, not line_base. (Patch from Andreas Arens,
3248 ari@obelix.av.rwth-aachen.de.)
3250 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
3251 look local if they're exported or undefined. Used to be done for
3254 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
3255 Get it from the looked-up symbol, instead of using the string from
3256 the input stream, which is no longer null-terminated.
3257 (LEX_PCT): New macro, defaults to 0.
3258 (lex_type): Use it for `%'.
3260 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
3261 (vip_op): Now static, and returns void. Callers changed. Added
3263 (vip): Ditto. Call as_fatal directly if a program bug is
3265 (op_hash): Let default initialization suffice.
3267 * Makefile.in (literal.o): Provide dependencies.
3269 * configure.in: Set new makefile variable OPCODES_LIB.

3274 * make-gas.com: Regenerated from new script.
3276 * configure.in (sparc*-*-lynxos*): Handle any version number
3277 suffix after "lynxos". Set emulation to lynx.

4803 as starting a CPP line directive unless it is a '#' and is the
4804 very first characters on the line (i.e., do not permit leading

4895 Delete dead code. Simplify.
4896 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
4897 applied are in range. Use bfd_put_32 rather than inserting each

4969 predefined register table.
4970 (pa_parse_number): Handle %rp in common register shortcut code.
4971 Consistently set return value to -1 for an error. Clean up error
4972 messages and only print them when "print_errors" is true. Handle
4973 empty string case like the HP assembler -- assume a value of
4976 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
4977 standard hpux include files to pick up various function decls.
4979 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in
4980 stdio.h. Delete bogus declaration of free. Get path to
4981 alloca-conf.h right.

4991 so GAS can attach unwind descriptor information to a BFD symbol.
4992 * config/tc-hppa.c (fix_new_hppa): If necessary attach unwind
4993 descriptor information to the BFD symbol.
4994 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

5012 of interest to the linker. ENTRY/EXIT relocations for SOM are
5013 an example of marker relocations.
5014 * write.c (write_relocs): Instead of assuming size of a relocation
5015 is 4 bytes, pick up the size from relocation itself.

5043 BFD_RELOC_MIPS_GPREL. Added new case a.
5044 (set_at, load_register, macro): Changed calls to macro_build to
5045 pass new argument for i, j and o cases.
5046 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
5047 special handling when generating SVR4 PIC code.
5048 (mips_ip, tc_get_register, s_frame): Use macros FP, SP, GP and AT
5049 rather than hard coded constants.
5050 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

5095 (FAKE_LABEL_NAME): New macro. Defines the default name used for
5097 * expr.c (make_expr_symbol): Delete DOT_LABEL_PREFIX code
5098 and instead simply use the string defined by FAKE_LABEL_NAME.
5099 (operand): Likewise.
5100 * read.c (s_stab_generic): Likewise.

5113 to control the use of space/subspace name aliases.
5114 (update_subspace): Accept space chain entry for containing space
5115 as a new parameter. All callers changed.
5116 (pa_get_label): Use current_space rather than pa_segment_to_space.

5118 (pa_undefine_label): Likewise.
5119 (md_begin): Change into the (possibly modified) text_section.
5120 (pa_parse_space_stmt): Create a new segment/space if create_flag
5121 is true, and the space name is not one of the two predefined spaces.

5128 subspace encountered. When not using aliases replace the default
5129 text, data, and bss segments with new ones.
5130 (create_new_subspace): When not using aliases each subspace has a

5267 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
5268 the table, require that the one without bit 0x1000000 set come

5379 OPTIONAL_REGISTER_PREFIX if either is already defined.
5381 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5383 * configure.in: Set bfd_gas for all sparc targets. Added facility
5384 for keeping or rejecting configurations still under development;
5385 default is to assume production environment, and reject configs
5386 still being worked on. Mark Elf configurations (except sparc and
5387 i386) as developmental. Deleted cases matching some generic names
5388 in favor of more specific names. (E.g., when we get Alpha

5405 through inclusion of tc-hppa.h. Delete all forward declarations
5406 for functions only used within tc-hppa.c, likewise for structures,
5407 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5408 conditional code in a few small places.
5410 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5411 structures, global variables, forward declarations together.

5413 conditional code -- try to group conditional code together
5414 into a few places. Make all functions and variables which
5415 are only used within tc-hppa.c static. PARAMize all functions.
5416 Add comments to functions. Delete unused functions, variables,
5417 #defines, etc. Delete unused members within structures. Delete
5418 ldil;ble hacks -- it is believed they were installed to work
5419 around old gas bugs. Avoid using mixed case for local
5420 functions, variables, and structures. Fix formatting problems
5421 not found by GNU-indent. Add FIXME notices for things which
5422 should be worked on the near future. Delete lots of old
5423 useless (1.36 PA-SOM) code.
5425 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
5426 field of the fixS structure. Needed to build unwind
5427 descriptors correctly.

5452 a multiple of the section alignment rather than always a
5455 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5456 bits are zero (eg they specify no relocations), then do not even
5457 bother adding their entries to thesymextn section.

5502 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5504 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5505 ELF, since the ELF object format does not have these type of
5506 relocations. Change the abort into as as_bad and return
5507 BFD_RELOC_NONE to silence compiler warnings.
5508 (md_assemble): Keep track of the instruction size. Allow white
5509 space between the $ and the constant for compatibility with older
5510 gases and other assemblers.

6517 Fri Jul 23 13:09:44 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
6519 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
6520 are also magic, and have special default flag settings.
6521 (obj_elf_frob_symbol): Since the return value from this function
6522 isn't used, don't bother calling obj_elf_write_symbol_p, since it
6523 doesn't accomplish anything else.

6535 undefined_section for the return value.
6537 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
6538 pseudo-op with a poc_handler field of NULL, ignore it and treat it

6555 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
6556 case to set obj_format=elf. Must go before i386-*-sysv* case that
6557 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
6558 *-*-solaris case, and move to before *-sysv* case that wants to
6559 set obj_format to coff.

6585 * Extensive changes to permit symbols to contain any expression
6586 type and to delay the computation of the expression until the
6587 value is actually needed. This permits setting symbols to values
6588 calculated based on object code size. Expressions were changed to
6589 no longer be in a section, to stop the overloading of segment and
6590 expression type that previously occurred.
6592 * as.c (big_section, pass1_section, diff_section, absent_section):
6594 (expr_section): Added (used for dummy symbols which hold

6678 (previous_section, previous_subsection): New vars.
6679 (obj_elf_section): Save current place in case DWARF code wants us
6680 to pop back to it. Handle unquoted section name as well as quoted
6681 section name. Don't crash on invalid strings.
6682 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

6794 sy_resolved and sy_resolving single bit fields.
6795 * symbols.c (symbol_new): Don't initialize sy_forward field.

7939 process relocs if there aren't any relocs to process. Avoids
7940 malloc/free bug on SCO too.

7994 dropping a space immediately following an identifier.
7995 * expr.c, write.c: Rewrote assert expressions to not use multiple
7996 lines; I don't think that can be done portably.
7997 * config/tc-mips.c (macro): Use $AT if target register is zero in
7998 load instruction, which it can be for a floating point load.

8072 prototypes for all static functions. Moved existing minimal
8073 debugging format support info #ifndef OBJ_ECOFF blocks.

8122 * make-gas.com: Find obstack.obj if it's not in the current
8124 * read.c (s_ignore): Don't declare is_end_of_line. It's
8125 redundant, and triggers a VMS gcc compiler bug.
8127 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8128 current segment as an argument. (Ignored in all cases but VMS.)
8129 All callers and definitions changed.

8183 constants are accepted, but symbolic values are not. GCC will not
8184 generate the latter currently.
8186 * frags.c (frag_init): New function.
8187 (zero_address_frag, bss_address_frag): Now initialized at run
8189 * as.c (main): Call frag_init.

8426 * config/tc-m68k.c: Removed some unused code.
8427 (tc_aout_fix_to_chars): Array nbytes_r_length is now const.
8429 * config/tc-m68k.h (TC_COUNT_RELOC): Don't emit reloc if only
8430 offset field is set.
8432 Fri Jan 8 05:44:49 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8434 * config/tc-sparc.c (sparc_ip): For %uhi and %ulo, if not
8435 ENV64, emit no reloc.

8439 * config/tc-sparc.c (architecture_requested, warn_on_bump,
8440 md_relax_table): Use default zero initialization.
8441 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
8442 latter, instead of selecting with preprocessor conditionals.
8444 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8446 * configure.in: recognise all sparclite variants
8448 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

8451 accidentally changed to use subseg_change where it should have
8454 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8456 * expr.c (operand): If character other than comma or newline is a
8457 logical end-of-line character, use the newline case.
8458 From Eric Youngdale:
8459 (operand): Set X_add_number field for floating-point numbers.
8460 (operand): Treat zero byte as end-of-operand.
8462 * configure.in (per-target): Look for with_bfd_assembler option.
8463 For now, only accept "no", until the merge is done.
8465 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8466 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8467 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8468 * read.c: Finish conversion to S_* macros in the VMS only
8469 parts of the program. Add "const" modifier to hex_value.
8470 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
8472 * expr.c: Add "const" modifier to hex_value.
8473 * symbols.c: Finish conversion to S_* macros in the VMS only
8474 parts of the program. Add "const" modifier to
8475 md_[long,short]_jump_size. Remove declaration of const_flag
8476 (which will be declared in obj-vms.h).
8477 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8478 Fix arguments to VMS_write_object_file.
8479 * config-gas.com: New file. Script for VMS systems to set up the
8480 configuration to build gas for VMS, and create config.status.
8481 * make-gas.com: Redone to work with new scheme.
8482 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8484 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8485 will swap bytes if needed on a big endian system. Use throughout
8487 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8488 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8489 types of malformed stabs. Change parsing algorithm so that we are
8490 more certain of having all of the information that we need on hand.
8491 * obj-vms.c (final_forward_reference): New function, used to help
8492 resolve the data types of as many struct elements as possible
8493 when some part of the struct is not fully defined by the compiler.
8494 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
8496 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8497 as symbols as well in the object file. Look for external functions
8498 that start with "__vt.", and turn them into variables, since the
8499 g++ compiler is incapable of doing this.
8500 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8502 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8503 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8504 have the name of the source file yet.
8505 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8507 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8509 * read.c (s_data): Always use "data_section", since it'll map to
8510 SEG_DATA or SEG_E1 if needed.
8511 (s_lcomm): Likewise with bss_section.
8512 (s_fill): Use memset, not bzero.
8514 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
8516 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

8530 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
8531 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

8535 (section_alignment): Declare only if not BFD_ASSEMBLER.
8536 (big_section, reg_section, pass1_section, diff_section,
8537 absent_section, text_section, data_section, bss_section): If
8538 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8539 mapping to segT enum values.
8540 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8541 if these are used or defined, if BFD_ASSEMBLER.
8542 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8543 subseg_new split into two functions.
8544 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8546 * as.h (volatile): Don't define if already defined.
8547 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8549 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8550 declare with format attribute for -Wformat checking.
8552 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8554 * app.c, config/tc-*.c: Don't include read.h, since it is already
8557 * These are based on patches from Minh Tran-le
8558 <mtranle@paris.intellicorp.com>.
8559 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8560 obj_format coffbfd and gas_target i386coff for target.
8561 (i[34]86-*-isc*): New host (uses sysv).
8562 * config/i386aix.mt: Removed (no longer used).
8563 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8565 (LDFLAGS): Added, defined as -shlib.
8566 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8567 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8568 (DOT_LABEL_PREFIX): Define.
8569 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8570 name rather than L0\001.
8571 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8573 * symbols.c, symbols.h (local_bss_counter): Removed.
8574 * write.c (write_object_file): bss no longer uses
8575 local_bss_counter. Pass correct data and bss size to
8576 VMS_write_object_file.

8582 (size_section): Restored sanity check.
8583 (do_relocs_for): Base section address on s_paddr rather than
8584 computing it. Adjust a29k R_IHIHALF special case to account for
8585 section paddr (used to require paddr to be zero). If there are no
8586 reclos, set s_relptr to 0. Set relocation size in object_headers.
8587 (fill_section): Always set s_vaddr here, removing
8588 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8589 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8590 Set STYP_INFO for .comment.
8591 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
8592 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

8594 H_{SET,GET}_* macros.
8595 (do_linenos_for): Set lineno size in object_headers.
8596 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8597 set s_vaddr here. If string_byte_count remains 4, set it back to
8598 0, and only write strings out if there are some. Call
8599 fill_section before do_relocs_for and do_linenos_for.
8600 (obj_coff_section): Handle optional quoted second argument giving
8601 section characteristics.
8602 (obj_coff_bss): Added to handle .bss.
8603 (obj_coff_ident): Added to handle .ident (puts string in .comment
8605 (obj_coff_lcomm): Put common symbols in .bss, not .data.
8606 (fixup_mdeps): Change to segment. Call frag_wane after
8608 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8609 adjustment (already happened only for common symbols, but this is
8611 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8612 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8623 (do_scrub_next_char): For \", return " not '.
8624 (symbol_chars): Now const.
8626 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8627 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8629 * config/obj-coff.h: Don't use #elif.
8631 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8632 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
8634 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

8658 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8659 using ZERO_BASED_SEGMENTS.
8660 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8661 never set segment address for SEG_E2 (.bss) and don't write out
8662 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8663 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8664 definitions, and don't merge tags with non-tags. Check for .bf
8665 rather than just checking whether the second character is b and
8666 the third character is f.
8667 (obj_coff_val): gcc can generate values which we don't handle
8668 correctly; discard information for now, since it only affects the
8669 debugging information.
8670 (tag_find_or_name): Don't insert tags in the symbol table.
8671 (yank_symbols): Don't merge labels.
8672 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8854 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
8855 constant will not fit in an immediate field.
8856 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

8893 * Support for i386-sysv.
8894 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
8895 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
8896 be used to set them all to zero as was done before.
8897 (fill_section): segment addresses now set in write_object_file.
8898 (fill_section): Don't set STYP_NOLOAD for .bss section.
8899 (fixup_segment): 386 uses strange common symbol format.
8900 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
8901 compatibility with SVR3.2 linker.
8902 * configure.in: i386-sysv and i386-sco use coffbfd.
8904 * app.c (do_scrub_next_char): discard whitespace after a label.

8913 fix i960+non-bfd coff bit rot.
8914 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
8915 support for C source listings. (obj_coff_endef): look in the right
8916 part of the symbol for the symbol name
8918 * tc-m68k.c (get_num): make it work for all segments, not just the
8921 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

8932 * tc-z8k.c: lots of bug fixes
8934 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8936 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8937 #elif, since it is not supported by old compilers.
8938 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8939 couple of expressions in tc-m68k.c.
8941 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8943 * read.c (cons): If NO_RELOC is defined, use it.
8945 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8947 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8949 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8950 local labels to start with a .) and set REGISTER_PREFIX to %.
8951 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

8969 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8970 sections starting from zero, rather than making them consecutive.
8971 This makes subsequent reloc calculations easier, esp if the object
8972 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8973 allocate lcomm in .data rather than in .bss. It seems that some
8974 tools can't cope with a non-zero sized bss before linkage.
8976 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8978 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8997 * Makefile.in (install): if $(tooldir) exists, install as in
9000 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
9002 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
9003 .word is < -32768 or > 32767. The -J flag causes the error to be
9004 ignored. This is to catch over-sized switches generated by gcc on
9005 systems which don't support the broken .word hack.
9006 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
9007 write.c (fixup_segment): check for signed .word overflow if
9008 WARN_SIGNED_OVERFLOW_WORD.

9027 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
9029 * input-scrub.c (input_scrub_push): call input_file_begin, not
9031 messages.c (as_perror): print ": " between the passed in error and
9032 the strerror, like perror does.
9034 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

9037 From Steve Chamberlain:
9038 Makefile.in: Handle m68*-*-coff*.
9039 read.c, read.h: add mult argument to s_space
9041 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
9042 Motorola and MIT syntax; gas can now assemble either type of
9044 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

9051 (fixup_segment) set fx_subsy to 0.
9052 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9054 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9057 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9059 * Makefile.in (LIBS): Include opcode library.

9086 * config/tc-m68k.c (init_table): Now const. Always include 68851
9087 data, so that "bc" is available to 68040 cache instructions.
9088 Added "tt0", "tt1", and 68ec030 variants.
9089 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9090 (enum _register): Added TT0, TT1.
9091 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9092 line number correctly in "internal error" messages. Don't print
9093 architecture-mismatch message for operand errors.
9095 From Colin Smith (colin@wrs.com):
9096 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

9118 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9119 has already been formatted (but may still contain %-characters).
9122 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9124 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9125 written with indirection on the last two operands, which can be
9126 either data or address registers. Added a new operand type 'r'
9127 which accepts either register type. Added '(' to notend stuff in
9128 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9372 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9374 * write.c (write_object_file): For b.out format, round up section
9375 start addresses to match required alignment.
9377 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
9379 * Makefile.in (install): Install into $(tooldir)/bin, since that's
9380 where gcc looks for it.
9382 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
9384 * Makefile.in: Changed some lines to be less confusing for some
9387 * input-file.c: Conditionalize on _IOFBF, not VMS.
9389 * read.c, write.c: Change a series of ifdef/elif to
9390 ifdef/else/ifdef etc.
9392 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
9394 * symbols.c (fb_label_init): fix sizeof to memset.
9396 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
9398 * Makefile.in: install the man page.
9400 * Makefile.in: pass down MAKEINFO explicitly on info.
9402 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
9404 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
9406 * flonum-const.c: renamed flonum-konst.c to stop dos name
9409 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
9411 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
9412 tc-m68k.h to te-sun3.h.
9414 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
9416 * configure.in: vxworks68 gets te-sun3.h.
9418 * expr.c: remove limitation that local_labels_dollar or
9419 local_labels_fb must be < 10.
9421 * symbols.c: remove local_labels_dollar, replace with a function
9422 interface for a sparse array. All users adjusted.
9424 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
9426 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9428 * doc/Makefile.in: commented out line for building as-all.texinfo.
9431 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
9433 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
9435 * Makefile.in: added check target.
9437 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9439 * Makefile.in: added tooldir and program_prefix.
9441 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
9443 * write.{c,h} (fix_new): Make these declarations consistent.
9445 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
9447 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9450 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9452 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9454 * expr.c (operand): if can't work out what sort of operand it is,
9455 then look through FLT_CHARS for a hint.
9457 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9459 * Makefile.in, configure.in: removed traces of namesubdir,
9460 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9461 copyrights to '92, changed some from Cygnus to FSF.
9463 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9464 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9465 copyrights to '92, changed some from Cygnus to FSF.
9467 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9469 * expr.c: If an expression is single comma, then return with
9470 SEG_ABSENT rather than an error - since the sparc front end does
9471 really strange things with things like fbge,a
9473 * as.h: include bfd.h if using many sections
9474 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9475 local labels didn't work.
9476 * listing.c (list_symbol_table): don't core dump when there's no
9478 * write.c, write.h: call fix_new with the right number of args on
9480 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9483 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9485 * app.c: MRI compatibility - allow single quote to start a string.
9486 * as.c: fix typo recently introduced.
9487 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9488 * expr.c: Much rewriting, to accomodate MRI syntax for
9489 expressions. Also easier to read now.
9490 * listing.c: Put back defuns
9491 * read.c: modified to accept MRI syntax, put back listing pseudo
9492 ops so that an assembler built with NO_LISTING ignores list ops
9494 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9495 machine is a SPARC or a 29K.
9496 * config/obj-aout.c: added s_sect pseudo op
9497 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9498 fill in the timestamp.
9499 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9500 anymore, define all the relocs which the tc-<x> bit will use so we
9501 can translate from them to the coff types.
9502 * config/tc-a29k.c: reloc_type isn't ane enum any more
9503 * config/tc-m68k.c: Added NO_RELOC definition.
9505 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9507 * Makefile.in: put header files before C source for TAGS; remove
9508 references to non-existent syscalls.h.
9510 * read.c, write.c subsegs.c: back out the .bss changes.
9512 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9514 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9518 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9520 * symbols.c (local_label_name): symbols now start with ^A.
9522 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9523 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9524 generate these sections. .align: will use NOP_OPCODE or 0
9525 for padding. This is just for being nice to the
9528 * expr.c (operand): changed to generate local label "\001L0"
9529 starting with a ^A so that it is recognized as a local label.
9531 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9533 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9534 i/o opcodes - inb, inw, outb and outw. string manipulation with
9535 att syntax - scmp, slod, smov, ssca, ssto.
9537 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9538 to just after .file .
9540 In obj_crawl_symbol_chain() where it tries to put the external
9541 symbols apart, with the condition:
9542 (!S_IS_DEFINED(symbolP) &&
9543 !S_IS_DEBUG(symbolP) &&
9544 !SF_GET_STATICS(symbolP))
9545 it was moving too many symbols out. So I switch it back to the
9547 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9549 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9550 so that we don't use the F_RELFLG which make the linker complain
9551 that somebody has stripped the relocation info.
9553 Also, the AIX ld program require that the relocation table
9554 is sorted by r_vaddr like the standard ATT assembler does.
9556 [he also changed the sizeof(struct ...)'s into the coff
9557 style FOOSZ macros. I'm not sure this is right, but I can't
9558 remember why. xoxorich.]
9560 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9562 * Makefile.in, configure.in, doc: use the doc. Build it, install
9565 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9567 * read.c: white space and comments only.
9569 * configure.in: use the new atof-ns32.c for ns32k.
9571 * write.c: comment change only.
9573 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9574 aren't yet integrated.
9576 * tc-i860.[hc]: blew off the dust. Something must still be done
9577 about conflicting relocation types.
9579 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9582 * tc-i960.c, tc-sparc.c: white space and comments only.
9584 * tc-a29k.h: delete duplicate macro definition.
9586 * new file atof-ns32k.c copied from hack's last unreleased gas.
9588 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9590 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9593 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9594 ChangeLog's prior to this are sketchy at best. I have logs.
9595 They just aren't ChangeLogs.
9602 version-control: never
