237 all arguments have been processed.

492 and call emit_insn directly.
493 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
494 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
495 emit_bis_r): Likewise.

502 the value can't be resolved.
504 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
506 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
507 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

510 (mips_force_relocation): New function.
511 (md_apply_fix): Set fixP->fx_done appropriately.

520 * config/tc-mips.c (enum mips_pic_level): New enum.
521 (mips_pic): Change from int to enum mips_pic_level. Change all
522 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
523 (load_address): Handle EMBEDDED_PIC.
524 (macro): Handle EMBEDDED_PIC in all PIC cases.
525 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
526 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
527 -non_shared to use NO_PIC (this is how the Irix 5 assembler
528 works). Do not permit -G with SVR4_PIC.
529 (s_abicalls): Warn if -G was used, and force -G 0.
530 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
531 anything but a.out, not just for ELF. For ECOFF, don't generate a
532 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
534 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
536 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

542 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
544 * Makefile.in (config-stamp): If `defs' is defined, emit a
545 preprocessor directive to create a macro named by this value into
546 config.new; don't explicitly go for BFD_ASSEMBLER.
547 * configure.in: Define `defs', not `BFDDEF'. Set it to
548 MANY_SEGMENTS for any obj-coffbfd target.
549 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
550 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
552 (LOCAL_LOADLIBES): Deleted.
553 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
554 * config/m88kcoff.mt (TDEFINES): Ditto.

580 bfd_set_symtab is called.
581 (dump_section_relocs): Note whether a symbol is a section symbol
583 (adjust_reloc_syms): For now, always supply an absolute symbol for
584 fixups without symbols but not yet `done'. Use section_symbol to
585 get the symbol, instead of going directly for abs_symbol.
586 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
587 reloc is not a section symbol and is not in the symbol table.
588 (set_symtab): New function, broken out from write_object_file.
589 Counts symbol table instead of relying on an earlier count.
590 (write_object_file): Call set_symtab, but do it after potentially
591 invoking the *_frob_file macros. Don't bother counting symbols.
592 Call symbol_remove, instead of expanding it in place. Moved the
593 conditionalized `object_file_size' declaration down to
594 conditionalized block where it's used. When using the absolute
595 symbol for a fixup without a symbol, set sy_used_in_reloc.
596 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
597 the correct symbol for the absolute section.
599 * subsegs.c (section_symbol): Use symbol_new instead of
600 symbol_make, since we may want it to go into the symbol table.
601 Make the new symbol have internal linkage. If
602 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
603 symbol with the newly created GAS symbol.
604 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
605 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

612 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
613 (sparc_ip, label "immediate"): Reject constants for pcrel
614 instructions only if the relocation type indicates a "call"
615 instruction and the offset is within range of a "jmpl %g0". If
616 it's not in range, use the absolute section symbol plus an offset.
617 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
619 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
621 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
624 * configure.in: Eliminated all targets using obj-coff but not
625 defining BFD_ASSEMBLER; I think all such targets that are
626 supported will be matched by real CPU-OS combinations earlier in
628 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
629 some comments about the dpx2 configuration, but left it disabled,
630 since it couldn't be reached before.
631 (target a29k-amd-ebmonold): Deleted.
633 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

641 the 'j' operand if there are no further alternatives for this
644 * config/obj-coffbfd.c (adjust_stab_section): Initialize
645 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
646 is not SEG_UNKNOWN rather than checking whether it is >= 0.
648 * config/tc-mips.c (mips_align): Take new argument, label, and use
649 it instead of global insn_label.
650 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
651 call to mips_emit_delay and pass it to mips_align.
653 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
655 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
657 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
658 argument to a .callinfo directive. Don't loop forever on errors.
660 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
661 use pre-defined registers as arguments.
663 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
665 * write.c (write_object_file): Check both S_IS_LOCAL and
666 S_IS_EXTERNAL when deciding whether to discard a symbol.
668 * config-gas.com: Scan Makefile.in, not version.c, for current
669 version number. Delete all versions of temp files when finished
670 with them. Create config.h.
672 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
673 values to reduce number of lookups with S_GET_VALUE. Skip debug

675 holger@botbso.rhein-main.de.)
676 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
677 field. (Also from Holger Teutsch.) Watch for a would-be register
678 mask that spans frags.
680 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
681 this_base, not line_base. (Patch from Andreas Arens,
682 ari@obelix.av.rwth-aachen.de.)
684 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
685 look local if they're exported or undefined. Used to be done for
688 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

692 (lex_type): Use it for `%'.
694 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
695 (vip_op): Now static, and returns void. Callers changed. Added

2479 rather than hard coded constants.
2480 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

2697 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2698 the table, require that the one without bit 0x1000000 set come

2812 still being worked on. Mark Elf configurations (except sparc and
2813 i386) as developmental. Deleted cases matching some generic names
2814 in favor of more specific names. (E.g., when we get Alpha

2818 * config/tc-sparc.c (md_end): Function deleted.
2819 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

2831 through inclusion of tc-hppa.h. Delete all forward declarations
2832 for functions only used within tc-hppa.c, likewise for structures,
2833 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2834 conditional code in a few small places.
2836 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group

3992 * Extensive changes to permit symbols to contain any expression
3993 type and to delay the computation of the expression until the
3994 value is actually needed. This permits setting symbols to values
3995 calculated based on object code size. Expressions were changed to
3996 no longer be in a section, to stop the overloading of segment and
3997 expression type that previously occurred.
3999 * as.c (big_section, pass1_section, diff_section, absent_section):
4001 (expr_section): Added (used for dummy symbols which hold

4110 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
4111 calculating opP->isiz; this permits the expression size to be
4112 determined as well, later on.
4114 * expr.c (clean_up_expression): Don't cancel the subtraction of
4117 * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

4126 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
4128 * read.c (float_cons): Simplified parsing logic. If
4129 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
4131 * symbols.c (colon): Rather than a special case for TC_HPPA,
4132 use new macro tc_frob_label.
4133 * config/tc-hppa.h (tc_frob_label): Define.

5291 source directory, if that's not the current directory.
5293 * configure.in (per-host): Accept MIPS host with BSD version

5319 avoid some redefinition complaints on some systems.
5320 (const, volatile): Don't need these conditionally defined if we
5321 use CONST and VOLATILE from ansidecl.h.
5322 (seg_name): Use CONST, not const.
5324 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5326 * config/tc-mips.c: Reindented to GNU standards.

5330 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5331 (fixup_segment): Add a29k special case; the linker is not prepared
5332 to see a segment offset here.

5337 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5339 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5340 srcdir, might be in objdir.

5359 * Makefile.in (targ-cpu.o): Depend on config.h.
5361 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5363 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5364 dropping a space immediately following an identifier.
5365 * expr.c, write.c: Rewrote assert expressions to not use multiple
5366 lines; I don't think that can be done portably.
5367 * config/tc-mips.c (macro): Use $AT if target register is zero in
5368 load instruction, which it can be for a floating point load.
5370 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5391 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5393 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5394 to be on a single line.

5442 prototypes for all static functions. Moved existing minimal
5443 debugging format support info #ifndef OBJ_ECOFF blocks.

5492 * make-gas.com: Find obstack.obj if it's not in the current
5494 * read.c (s_ignore): Don't declare is_end_of_line. It's
5495 redundant, and triggers a VMS gcc compiler bug.
5497 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5498 current segment as an argument. (Ignored in all cases but VMS.)
5499 All callers and definitions changed.

5628 * read.c: Don't include ctype.h.
5629 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
5630 for now; should be machine-dependent.

5796 md_relax_table): Use default zero initialization.
5797 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5798 latter, instead of selecting with preprocessor conditionals.
5800 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5802 * configure.in: recognise all sparclite variants

5812 * expr.c (operand): If character other than comma or newline is a
5813 logical end-of-line character, use the newline case.
5814 From Eric Youngdale:
5815 (operand): Set X_add_number field for floating-point numbers.
5816 (operand): Treat zero byte as end-of-operand.
5818 * configure.in (per-target): Look for with_bfd_assembler option.
5819 For now, only accept "no", until the merge is done.
5821 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5822 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5828 * expr.c: Add "const" modifier to hex_value.
5829 * symbols.c: Finish conversion to S_* macros in the VMS only
5830 parts of the program. Add "const" modifier to
5831 md_[long,short]_jump_size. Remove declaration of const_flag
5832 (which will be declared in obj-vms.h).
5833 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5834 Fix arguments to VMS_write_object_file.
5835 * config-gas.com: New file. Script for VMS systems to set up the
5836 configuration to build gas for VMS, and create config.status.
5837 * make-gas.com: Redone to work with new scheme.
5838 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5840 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5841 will swap bytes if needed on a big endian system. Use throughout
5843 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5844 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5845 types of malformed stabs. Change parsing algorithm so that we are
5846 more certain of having all of the information that we need on hand.
5847 * obj-vms.c (final_forward_reference): New function, used to help
5848 resolve the data types of as many struct elements as possible
5849 when some part of the struct is not fully defined by the compiler.

5852 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5853 as symbols as well in the object file. Look for external functions
5854 that start with "__vt.", and turn them into variables, since the
5855 g++ compiler is incapable of doing this.
5856 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5858 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5859 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5860 have the name of the source file yet.
5861 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5863 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5865 * read.c (s_data): Always use "data_section", since it'll map to
5866 SEG_DATA or SEG_E1 if needed.
5867 (s_lcomm): Likewise with bss_section.
5868 (s_fill): Use memset, not bzero.
5870 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5892 (big_section, reg_section, pass1_section, diff_section,
5893 absent_section, text_section, data_section, bss_section): If
5894 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5895 mapping to segT enum values.
5896 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5897 if these are used or defined, if BFD_ASSEMBLER.
5898 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5899 subseg_new split into two functions.
5900 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5902 * as.h (volatile): Don't define if already defined.
5903 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5905 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5906 declare with format attribute for -Wformat checking.
5908 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5910 * app.c, config/tc-*.c: Don't include read.h, since it is already
5913 * These are based on patches from Minh Tran-le
5914 <mtranle@paris.intellicorp.com>.
5915 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5916 obj_format coffbfd and gas_target i386coff for target.
5917 (i[34]86-*-isc*): New host (uses sysv).
5918 * config/i386aix.mt: Removed (no longer used).
5919 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5921 (LDFLAGS): Added, defined as -shlib.
5922 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5923 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5924 (DOT_LABEL_PREFIX): Define.
5925 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5926 name rather than L0\001.
5927 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5929 * symbols.c, symbols.h (local_bss_counter): Removed.
5930 * write.c (write_object_file): bss no longer uses

5938 (size_section): Restored sanity check.
5939 (do_relocs_for): Base section address on s_paddr rather than
5940 computing it. Adjust a29k R_IHIHALF special case to account for
5941 section paddr (used to require paddr to be zero). If there are no
5942 reclos, set s_relptr to 0. Set relocation size in object_headers.
5943 (fill_section): Always set s_vaddr here, removing
5944 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5945 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5946 Set STYP_INFO for .comment.
5947 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5948 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5950 H_{SET,GET}_* macros.
5951 (do_linenos_for): Set lineno size in object_headers.
5952 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5953 set s_vaddr here. If string_byte_count remains 4, set it back to
5954 0, and only write strings out if there are some. Call
5955 fill_section before do_relocs_for and do_linenos_for.
5956 (obj_coff_section): Handle optional quoted second argument giving
5957 section characteristics.
5958 (obj_coff_bss): Added to handle .bss.
5959 (obj_coff_ident): Added to handle .ident (puts string in .comment

5979 (do_scrub_next_char): For \", return " not '.
5980 (symbol_chars): Now const.
5982 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5983 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5985 * config/obj-coff.h: Don't use #elif.
5987 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5988 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5990 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5992 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

6012 SEG_BSS, fill with NOP_OPCODE.
6013 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6014 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6015 using ZERO_BASED_SEGMENTS.
6016 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6017 never set segment address for SEG_E2 (.bss) and don't write out
6018 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6019 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6020 definitions, and don't merge tags with non-tags. Check for .bf
6021 rather than just checking whether the second character is b and
6022 the third character is f.
6023 (obj_coff_val): gcc can generate values which we don't handle
6024 correctly; discard information for now, since it only affects the
6025 debugging information.
6026 (tag_find_or_name): Don't insert tags in the symbol table.
6027 (yank_symbols): Don't merge labels.
6028 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6048 power-of-two alignment for .align.
6050 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
6051 and leave everything else alone.

6174 could be doing emulation.
6176 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6179 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

6292 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6293 #elif, since it is not supported by old compilers.
6294 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6295 couple of expressions in tc-m68k.c.
6297 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6299 * read.c (cons): If NO_RELOC is defined, use it.

6325 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6326 sections starting from zero, rather than making them consecutive.
6327 This makes subsequent reloc calculations easier, esp if the object
6328 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6329 allocate lcomm in .data rather than in .bss. It seems that some
6330 tools can't cope with a non-zero sized bss before linkage.
6332 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6334 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6353 * Makefile.in (install): if $(tooldir) exists, install as in
6356 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6358 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6359 .word is < -32768 or > 32767. The -J flag causes the error to be
6360 ignored. This is to catch over-sized switches generated by gcc on
6361 systems which don't support the broken .word hack.
6362 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6363 write.c (fixup_segment): check for signed .word overflow if
6364 WARN_SIGNED_OVERFLOW_WORD.

6383 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6385 * input-scrub.c (input_scrub_push): call input_file_begin, not
6387 messages.c (as_perror): print ": " between the passed in error and
6388 the strerror, like perror does.

6393 From Steve Chamberlain:
6394 Makefile.in: Handle m68*-*-coff*.
6395 read.c, read.h: add mult argument to s_space
6397 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6398 Motorola and MIT syntax; gas can now assemble either type of
6400 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6406 (write_object_file) call fixup_mdeps
6407 (fixup_segment) set fx_subsy to 0.
6408 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6410 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6413 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6415 * Makefile.in (LIBS): Include opcode library.
6417 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6440 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6442 * config/tc-m68k.c (init_table): Now const. Always include 68851
6443 data, so that "bc" is available to 68040 cache instructions.
6444 Added "tt0", "tt1", and 68ec030 variants.
6445 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6446 (enum _register): Added TT0, TT1.
6447 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6448 line number correctly in "internal error" messages. Don't print
6449 architecture-mismatch message for operand errors.
6451 From Colin Smith (colin@wrs.com):
6452 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6453 than install_operand.

6469 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6470 so that we can assemble hand-written libgcc code.

6474 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6475 has already been formatted (but may still contain %-characters).
6478 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6480 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6481 written with indirection on the last two operands, which can be
6482 either data or address registers. Added a new operand type 'r'
6483 which accepts either register type. Added '(' to notend stuff in
6484 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6486 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6502 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6503 their not having symbols associated.
6505 * tc-i960.c (norelax, instrument_branches): Default initializer is
6507 (linkrelax): Delete variable definition.

6531 being used with args swapped, causing occasional lossage when
6532 refilling buffers after an include file.

6542 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6543 selected architecture, print a message saying so and listing what

6733 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6735 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6736 where gcc looks for it.
6738 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6740 * Makefile.in: Changed some lines to be less confusing for some

6806 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6808 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6810 * expr.c (operand): if can't work out what sort of operand it is,
6811 then look through FLT_CHARS for a hint.
6813 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6815 * Makefile.in, configure.in: removed traces of namesubdir,
6816 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6817 copyrights to '92, changed some from Cygnus to FSF.
6819 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6820 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6821 copyrights to '92, changed some from Cygnus to FSF.
6823 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6825 * expr.c: If an expression is single comma, then return with
6826 SEG_ABSENT rather than an error - since the sparc front end does
6827 really strange things with things like fbge,a
6829 * as.h: include bfd.h if using many sections
6830 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6831 local labels didn't work.
6832 * listing.c (list_symbol_table): don't core dump when there's no
6834 * write.c, write.h: call fix_new with the right number of args on
6836 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6839 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6841 * app.c: MRI compatibility - allow single quote to start a string.
6842 * as.c: fix typo recently introduced.
6843 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6844 * expr.c: Much rewriting, to accomodate MRI syntax for
6845 expressions. Also easier to read now.
6846 * listing.c: Put back defuns
6847 * read.c: modified to accept MRI syntax, put back listing pseudo
6848 ops so that an assembler built with NO_LISTING ignores list ops
6850 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6851 machine is a SPARC or a 29K.
6852 * config/obj-aout.c: added s_sect pseudo op
6853 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6854 fill in the timestamp.
6855 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6856 anymore, define all the relocs which the tc-<x> bit will use so we
6857 can translate from them to the coff types.
6858 * config/tc-a29k.c: reloc_type isn't ane enum any more
6859 * config/tc-m68k.c: Added NO_RELOC definition.
6861 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6863 * Makefile.in: put header files before C source for TAGS; remove
6864 references to non-existent syscalls.h.
6866 * read.c, write.c subsegs.c: back out the .bss changes.
6868 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6870 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6874 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6876 * symbols.c (local_label_name): symbols now start with ^A.
6878 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6879 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6880 generate these sections. .align: will use NOP_OPCODE or 0
6881 for padding. This is just for being nice to the
6884 * expr.c (operand): changed to generate local label "\001L0"
6885 starting with a ^A so that it is recognized as a local label.
6887 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6889 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6890 i/o opcodes - inb, inw, outb and outw. string manipulation with
6891 att syntax - scmp, slod, smov, ssca, ssto.
6893 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6894 to just after .file .
6896 In obj_crawl_symbol_chain() where it tries to put the external
6897 symbols apart, with the condition:
6898 (!S_IS_DEFINED(symbolP) &&
6899 !S_IS_DEBUG(symbolP) &&
6900 !SF_GET_STATICS(symbolP))
6901 it was moving too many symbols out. So I switch it back to the
6903 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6905 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6906 so that we don't use the F_RELFLG which make the linker complain
6907 that somebody has stripped the relocation info.
6909 Also, the AIX ld program require that the relocation table
6910 is sorted by r_vaddr like the standard ATT assembler does.
6912 [he also changed the sizeof(struct ...)'s into the coff
6913 style FOOSZ macros. I'm not sure this is right, but I can't
6914 remember why. xoxorich.]
6916 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6918 * Makefile.in, configure.in, doc: use the doc. Build it, install

6923 * read.c: white space and comments only.
6925 * configure.in: use the new atof-ns32.c for ns32k.
6927 * write.c: comment change only.
6929 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6930 aren't yet integrated.
6932 * tc-i860.[hc]: blew off the dust. Something must still be done
6933 about conflicting relocation types.
6935 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6938 * tc-i960.c, tc-sparc.c: white space and comments only.
6940 * tc-a29k.h: delete duplicate macro definition.
6942 * new file atof-ns32k.c copied from hack's last unreleased gas.
6944 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6946 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6949 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6950 ChangeLog's prior to this are sketchy at best. I have logs.
6951 They just aren't ChangeLogs.
6955 version-control: never
