2497 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
2498 it's better to use the one in libiberty.
2500 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2502 * symbols.c (resolve_symbol_value, case O_symbol): Undo last

2540 * Makefile.in (comparison): When comparing as.new or gasp.new, try
2541 running the binary through sed to avoid differences due to

2560 ecoff_frob_symbol if appropriate.
2562 * write.c (fixup_segment): For i386 elf and coff (for now), don't

2666 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2668 * configure.in: Set bfd_gas for all sparc targets in one place,
2669 instead of separately for each. Correctly handle user-supplied
2670 "--enable-bfd-gas" option.
2672 * gdbinit.in: Move "break abort" to end, in case gdb complains.
2674 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

2682 (indent_level): No longer static.
2683 (print_symbol_value_1): Don't print frag address if it matches

2689 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
2690 not symbol_new, for symbols holding expression values.

2692 * write.c (fix_new_exp): Handle O_add by creating an
2693 expression-valued symbol, and calling fix_new_exp recursively.
2694 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
2695 undefined symbol and a constant, fold the constant into the fixup,
2696 and refer to the undefined symbol directly. Then process the
2697 fixup again from scratch.
2698 (write_object_file): Before calling adjust_reloc_syms, make a pass
2699 through the symbol list trying to resolve values.
2701 * write.c (print_fixup): New routine, for debugging.
2702 (write_relocs): Call bfd_install_relocation. Deleted various

2720 * write.c (write_relocs): Add file name and line number to
2721 as_fatal calls. Handle bfd_reloc_overflow case specifically when
2722 RELOC_EXPANSION_POSSIBLE.
2724 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
2726 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
2727 here. Use them for deciding which PRINTF*LIKE macro definitions

2731 default definitions matching what we were doing before.
2732 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
2733 always use the varargs form if not using stdarg. It's safe to
2734 always use vfprintf, because libiberty will provide it if the
2735 native system doesn't. Also, always make format be const.
2736 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

2754 false (if defined) as well as checking for reg_section.
2755 (listing_listing): Iterate fetching lines while line number is too
2756 low, and we haven't run off the end of the input file.
2758 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
2760 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

2771 * symbols.c (copy_symbol_attributes): New function. Copies BFD
2772 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
2773 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
2774 zero. Don't call obj_frob_forward_symbol.

2776 X_add_number is zero.
2777 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.

2783 md_estimate_size_before_relax, md_ri_to_chars,
2784 md_create_short_jump, md_create_long_jump.
2785 (brtab_emit): Use data_section, not SEG_DATA.
2787 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2789 * config/vms-conf.h: new file, manually derived from conf.in.

2803 * config/tc-mips.c (insns_since_cache_access): Remove.
2804 (append_insn): Remove setting of insns_since_cache_access, and
2805 special 4600 handling; it turns out not to be required.
2807 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
2809 * config/tc-mips.c (md_shortopts): Remove E.
2810 (md_longopts): Add EB and EL.
2811 (md_parse_option): Handle -EB and -EL as separate options, rather
2812 than as a single -E option with an argument.

2816 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
2817 involving global symbols too.
2819 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2821 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
2823 * configure.in: Test for remove, not delete. Fix cross-assembler

2839 representation (only enum bitfields can avoid being bitstrings).
2840 (bitfield_suffix, setup_basic_type): new routines.
2841 (VMS_typedef_parse): use them. Now recognize bitfields of all
2842 integral types, not just type `int'. Caveat: the representation
2843 used for bitfields still does not work for objects placed in
2844 registers, and gcc's optimizer sometimes puts small structs there.
2846 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
2848 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
2849 bit from const_flag.
2850 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.

2852 and declare the latter.
2853 * config/obj-vms.c (vax_g_doubles): declare this file-scope
2855 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
2856 (vms_check_for_special_label): new routine (tc_frob_label).
2857 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
2858 and `gcc2_compiled.' labels; they won't reach here any more.
2859 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
2860 double', use `vax_g_doubles' flag to select type of double.
2861 (VMS_write_object_file) [traceback setup]: don't pass symbols

2870 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
2871 gets requested. [All the HACK_DEC_C_STARTUP code appears to
2872 be obsolete; gcc does it automatically for vms target. It's
2873 also misnamed, because it is for the "VAX C" run-time library,
2874 not the newer "DEC C" one which has much different startup code.]
2875 {various}: use `S_SET_xxx(symbol,new_value)' rather than
2876 `S_GET_xxx(symbol) = new_value'.

2901 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
2902 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
2903 pointer to 32 bits of unwind info.

2918 to modify the gcc-vms driver when intending to use with gcc 1.x.
2919 * as.c (parse_options): suppress 'v' from std_short_options and
2920 eliminate VMS-specific conditional initialization;

2925 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
2926 for O_big literal operands (double floats and long long ints);
2927 [VMS, md_shortopts]: add second colon after 'v';
2928 (md_parse_options) [VMS, case 'v']: check for argument, so

3127 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
3128 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
3129 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
3130 message to try to ease confusion about autoconf's

3925 * read.c (emit_expr): Use memset to zero out memory, rather than
3926 going through md_number_to_chars. This permits handling symbolic

3980 (control_regs): New pointer.
3981 (m68k_ip): Use control_regs instead of testing CPU every time.

3983 print 68060 for mfloat, too.
3984 (m68k_init_after_args): Handle "68060". Use m68040up for making
3985 m68851 choice. Set control_regs.

4497 elf_tc_make_sections stuff. It was there to support PA braindamage
4498 which has been fixed, and in the case of elf_tc_make_sections is
4499 redundant with elf_tc_final_processing.

4636 works). Do not permit -G with SVR4_PIC.
4637 (s_abicalls): Warn if -G was used, and force -G 0.
4638 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

4687 * write.c (symbol_table_frozen): New variable, to be set after
4688 bfd_set_symtab is called.
4689 (dump_section_relocs): Note whether a symbol is a section symbol
4691 (adjust_reloc_syms): For now, always supply an absolute symbol for
4692 fixups without symbols but not yet `done'. Use section_symbol to
4693 get the symbol, instead of going directly for abs_symbol.
4694 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
4695 reloc is not a section symbol and is not in the symbol table.
4696 (set_symtab): New function, broken out from write_object_file.
4697 Counts symbol table instead of relying on an earlier count.
4698 (write_object_file): Call set_symtab, but do it after potentially
4699 invoking the *_frob_file macros. Don't bother counting symbols.
4700 Call symbol_remove, instead of expanding it in place. Moved the
4701 conditionalized `object_file_size' declaration down to
4702 conditionalized block where it's used. When using the absolute
4703 symbol for a fixup without a symbol, set sy_used_in_reloc.
4704 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
4705 the correct symbol for the absolute section.
4707 * subsegs.c (section_symbol): Use symbol_new instead of
4708 symbol_make, since we may want it to go into the symbol table.
4709 Make the new symbol have internal linkage. If
4710 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
4711 symbol with the newly created GAS symbol.
4712 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
4713 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

4720 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
4721 (sparc_ip, label "immediate"): Reject constants for pcrel
4722 instructions only if the relocation type indicates a "call"
4723 instruction and the offset is within range of a "jmpl %g0". If
4724 it's not in range, use the absolute section symbol plus an offset.
4725 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
4727 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
4729 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
4732 * configure.in: Eliminated all targets using obj-coff but not
4733 defining BFD_ASSEMBLER; I think all such targets that are
4734 supported will be matched by real CPU-OS combinations earlier in
4736 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
4737 some comments about the dpx2 configuration, but left it disabled,
4738 since it couldn't be reached before.
4739 (target a29k-amd-ebmonold): Deleted.

4749 the 'j' operand if there are no further alternatives for this
4752 * config/obj-coffbfd.c (adjust_stab_section): Initialize
4753 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
4754 is not SEG_UNKNOWN rather than checking whether it is >= 0.
4756 * config/tc-mips.c (mips_align): Take new argument, label, and use
4757 it instead of global insn_label.
4758 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
4759 call to mips_emit_delay and pass it to mips_align.
4761 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4763 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
4765 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
4766 argument to a .callinfo directive. Don't loop forever on errors.

4773 * write.c (write_object_file): Check both S_IS_LOCAL and
4774 S_IS_EXTERNAL when deciding whether to discard a symbol.
4776 * config-gas.com: Scan Makefile.in, not version.c, for current
4777 version number. Delete all versions of temp files when finished
4778 with them. Create config.h.
4780 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
4781 values to reduce number of lookups with S_GET_VALUE. Skip debug
4782 symbols to avoid "a really nasty bug". (From Holger Teutsch,
4783 holger@botbso.rhein-main.de.)
4784 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
4785 field. (Also from Holger Teutsch.) Watch for a would-be register
4786 mask that spans frags.
4788 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
4789 this_base, not line_base. (Patch from Andreas Arens,
4790 ari@obelix.av.rwth-aachen.de.)

4793 look local if they're exported or undefined. Used to be done for
4796 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

4800 (lex_type): Use it for `%'.
4802 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

4852 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
4853 0xffff for 'j' to be compatible with MIPS assembler. These

6928 still being worked on. Mark Elf configurations (except sparc and
6929 i386) as developmental. Deleted cases matching some generic names
6930 in favor of more specific names. (E.g., when we get Alpha

6957 are only used within tc-hppa.c static. PARAMize all functions.
6958 Add comments to functions. Delete unused functions, variables,
6959 #defines, etc. Delete unused members within structures. Delete
6960 ldil;ble hacks -- it is believed they were installed to work
6961 around old gas bugs. Avoid using mixed case for local
6962 functions, variables, and structures. Fix formatting problems
6963 not found by GNU-indent. Add FIXME notices for things which
6964 should be worked on the near future. Delete lots of old

8127 * Extensive changes to permit symbols to contain any expression
8128 type and to delay the computation of the expression until the
8129 value is actually needed. This permits setting symbols to values
8130 calculated based on object code size. Expressions were changed to
8131 no longer be in a section, to stop the overloading of segment and
8132 expression type that previously occurred.
8134 * as.c (big_section, pass1_section, diff_section, absent_section):
8136 (expr_section): Added (used for dummy symbols which hold

8220 (previous_section, previous_subsection): New vars.
8221 (obj_elf_section): Save current place in case DWARF code wants us
8222 to pop back to it. Handle unquoted section name as well as quoted
8223 section name. Don't crash on invalid strings.
8224 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

8261 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
8263 * read.c (float_cons): Simplified parsing logic. If
8264 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

8284 (macro): Call mips_emit_delays before setting mips_noreorder.
8285 Increment and decrement mips_noreorder rather than using

8312 (omagic): Removed unused variable.
8314 * Preliminary support for m88k-coff.

8333 * Removed sy_forward and replaced it with an undefined expression
8334 as the value of a symbol.
8335 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
8336 sy_resolved and sy_resolving single bit fields.
8337 * symbols.c (symbol_new): Don't initialize sy_forward field.
8338 (resolve_symbol_value): New function to adjust symbol value by
8339 fragment address, using recursion to resolve forward symbols.

8341 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
8342 expression rather than setting symbolP->sy_forward.
8343 * write.c (write_object_file): Use resolve_symbol_value on
8344 symbols, keeping the common case (the old behaviour) inline.

9371 than ECOFF line number information.
9372 (obj_ecoff_stab): Accept non-zero values for stabs line number.

9431 * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
9432 the bottom (make expands variables in dependencies when the
9433 dependencies are read, not when they are used).
9435 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
9436 a29k .bss section; the mondfe program doesn't like it.

9457 source directory, if that's not the current directory.
9459 * configure.in (per-host): Accept MIPS host with BSD version

9480 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
9481 process relocs if there aren't any relocs to process. Avoids
9482 malloc/free bug on SCO too.

9485 avoid some redefinition complaints on some systems.
9486 (const, volatile): Don't need these conditionally defined if we
9487 use CONST and VOLATILE from ansidecl.h.
9488 (seg_name): Use CONST, not const.
9490 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
9492 * config/tc-mips.c: Reindented to GNU standards.
9494 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
9496 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
9497 (fixup_segment): Add a29k special case; the linker is not prepared
9498 to see a segment offset here.
9500 * app.c (do_scrub_next_char): Added new state, 10, modifying state
9501 9 to only keep a space in between identifier characters.
9503 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
9505 * Makefile.in: add dvi target; as-$(config).texinfo might live in
9506 srcdir, might be in objdir.
9508 * doc/Makefile.in: dvi depends on as.dvi

9526 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
9527 bignums, but don't emit error message.
9529 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
9531 * Makefile.in (targ-cpu.o): Depend on config.h.
9533 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
9535 * app.c (do_scrub_next_char): Added new state, 9, to avoid
9536 dropping a space immediately following an identifier.
9537 * expr.c, write.c: Rewrote assert expressions to not use multiple
9538 lines; I don't think that can be done portably.
9539 * config/tc-mips.c (macro): Use $AT if target register is zero in
9540 load instruction, which it can be for a floating point load.
9542 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

9550 * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
9553 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
9554 z8k-opc.h, not z8k.h.
9556 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
9559 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
9561 * configure.in: recognize sparc-sun-solaris2* instead of -solaris2
9563 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
9565 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
9566 to be on a single line.
9568 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
9570 * Makefile.in (config.h): Create file, writing out definitions of

9610 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
9611 (struct loc, struct proc, struct file): Moved to tc-mips.c within

9614 prototypes for all static functions. Moved existing minimal
9615 debugging format support info #ifndef OBJ_ECOFF blocks.
9616 (macro_build_lui): Eliminated sign_extend argument, because ECOFF
9617 does not support a non sign extended high 16 bits reloc. Adjusted
9618 all callers accordingly.
9619 (tc_get_register): Renamed from get_register, and made non-static.
9621 * config/mips-big.mt, config/mips-lit.mt: New files. Define

9664 * make-gas.com: Find obstack.obj if it's not in the current
9666 * read.c (s_ignore): Don't declare is_end_of_line. It's
9667 redundant, and triggers a VMS gcc compiler bug.
9669 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
9670 current segment as an argument. (Ignored in all cases but VMS.)
9671 All callers and definitions changed.

9687 (obj_elf_xstab): New routine.
9688 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
9689 argument to s_ignore. Put "#if 0" around unused code.
9690 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
9691 Call elf_xstabs for .stabs and .xstabs operators.
9693 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
9695 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
9698 * configure.in: mips-bsd configuration was missing format spec.
9701 * Makefile.in (Makefile): Depends on configure.in.
9703 * config/tc-mips.c (append_insn): Don't check for alignment of
9704 frag in memory; alignment of instructions in section is a separate

9724 * config/tc-sparc.c (s_xword): Now call big_cons, so large
9725 constants are accepted, but symbolic values are not. GCC will not
9726 generate the latter currently.
9728 * frags.c (frag_init): New function.
9729 (zero_address_frag, bss_address_frag): Now initialized at run
9731 * as.c (main): Call frag_init.

9763 referencing symbol structure members.
9764 (obj_aout_frob_symbol) [BFD_ASSEMBLER]: New function.
9766 * as.h (struct frag): Reordered a couple of fields for better

9774 obj_frob_file, obj_frob_symbol, tc_frob_symbol if defined.
9775 (fixup_segment): Make sure common-section symbols get treated the
9776 same as undefined symbols.
9777 (fix_new) [BFD_ASSEMBLER]: Argument r_type is of type
9778 bfd_reloc_code_real_type. Use seg_fix_{root,tail}P derived from
9780 * write.h (fix_new): Update prototype.
9782 * tc.h (md_operand, md_convert_frag, tc_headers_hook,
9783 md_section_align, md_undefined_symbol): Don't provide prototypes
9784 if these are defined as macros.
9785 (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
9788 * symbols.c (symbol_new): Argument NAME is now pointer to const.
9789 Simplified STRIP_UNDERSCORE code. Remove assumptions about null
9790 pointers in freshly allocated storage. [BFD_ASSEMBLER]: Get new

9806 (subseg_set) [BFD_ASSEMBLER]: New function; change to a possibly
9807 new section/subsection.
9809 * read.c: Don't include ctype.h.
9810 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
9811 for now; should be machine-dependent.
9813 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
9814 targets, forcing BFD use.
9816 Wed Feb 17 18:59:03 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
9818 * config/tc-sparc.c: Use PARAMS macro for static function

9981 * config/tc-sparc.c (architecture_requested, warn_on_bump,
9982 md_relax_table): Use default zero initialization.
9983 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

9996 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
9998 * expr.c (operand): If character other than comma or newline is a
9999 logical end-of-line character, use the newline case.
10000 From Eric Youngdale:
10001 (operand): Set X_add_number field for floating-point numbers.
10002 (operand): Treat zero byte as end-of-operand.
10004 * configure.in (per-target): Look for with_bfd_assembler option.
10005 For now, only accept "no", until the merge is done.
10007 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
10008 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
10009 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
10010 * read.c: Finish conversion to S_* macros in the VMS only
10011 parts of the program. Add "const" modifier to hex_value.
10012 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
10014 * expr.c: Add "const" modifier to hex_value.
10015 * symbols.c: Finish conversion to S_* macros in the VMS only
10016 parts of the program. Add "const" modifier to
10017 md_[long,short]_jump_size. Remove declaration of const_flag
10018 (which will be declared in obj-vms.h).
10019 * write.c: Add "const" modifier to md_[long,short]_jump_size.
10020 Fix arguments to VMS_write_object_file.
10021 * config-gas.com: New file. Script for VMS systems to set up the
10022 configuration to build gas for VMS, and create config.status.
10023 * make-gas.com: Redone to work with new scheme.
10024 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
10026 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
10027 will swap bytes if needed on a big endian system. Use throughout
10029 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
10030 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
10031 types of malformed stabs. Change parsing algorithm so that we are
10032 more certain of having all of the information that we need on hand.
10033 * obj-vms.c (final_forward_reference): New function, used to help
10034 resolve the data types of as many struct elements as possible
10035 when some part of the struct is not fully defined by the compiler.
10036 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
10038 * obj-vms.c (VMS_write_object_file): Define all vtable psects
10039 as symbols as well in the object file. Look for external functions

10041 g++ compiler is incapable of doing this.
10042 * tc-vax.c: Add '1' option for backward compatibility with older GCC
10044 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

10049 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
10051 * read.c (s_data): Always use "data_section", since it'll map to
10052 SEG_DATA or SEG_E1 if needed.
10053 (s_lcomm): Likewise with bss_section.
10054 (s_fill): Use memset, not bzero.
10056 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
10058 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

10075 otherwise, use seg_name array.
10076 (seg_name): Declare only if not BFD_ASSEMBLER.
10077 (section_alignment): Declare only if not BFD_ASSEMBLER.
10078 (big_section, reg_section, pass1_section, diff_section,
10079 absent_section, text_section, data_section, bss_section): If
10080 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
10081 mapping to segT enum values.
10082 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
10083 if these are used or defined, if BFD_ASSEMBLER.
10084 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
10085 subseg_new split into two functions.
10086 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
10088 * as.h (volatile): Don't define if already defined.

10092 declare with format attribute for -Wformat checking.
10094 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
10096 * app.c, config/tc-*.c: Don't include read.h, since it is already
10099 * These are based on patches from Minh Tran-le
10100 <mtranle@paris.intellicorp.com>.
10101 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
10102 obj_format coffbfd and gas_target i386coff for target.
10103 (i[34]86-*-isc*): New host (uses sysv).
10104 * config/i386aix.mt: Removed (no longer used).
10105 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
10106 (MINUS_G): Removed.
10107 (LDFLAGS): Added, defined as -shlib.
10108 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
10109 * config/te-sco386.h (LOCAL_LABEL): Don't define.
10110 (DOT_LABEL_PREFIX): Define.
10111 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
10112 name rather than L0\001.
10113 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
10115 * symbols.c, symbols.h (local_bss_counter): Removed.
10116 * write.c (write_object_file): bss no longer uses
10117 local_bss_counter. Pass correct data and bss size to
10118 VMS_write_object_file.
10119 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
10120 argument, rather than using local_bss_counter.

10124 (size_section): Restored sanity check.
10125 (do_relocs_for): Base section address on s_paddr rather than
10126 computing it. Adjust a29k R_IHIHALF special case to account for
10127 section paddr (used to require paddr to be zero). If there are no
10128 reclos, set s_relptr to 0. Set relocation size in object_headers.
10129 (fill_section): Always set s_vaddr here, removing
10130 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
10131 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
10132 Set STYP_INFO for .comment.
10133 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
10134 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
10135 (crawl_symbols): Handle 8 character section name correctly. Use
10136 H_{SET,GET}_* macros.
10137 (do_linenos_for): Set lineno size in object_headers.
10138 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
10139 set s_vaddr here. If string_byte_count remains 4, set it back to
10140 0, and only write strings out if there are some. Call
10141 fill_section before do_relocs_for and do_linenos_for.
10142 (obj_coff_section): Handle optional quoted second argument giving
10143 section characteristics.
10144 (obj_coff_bss): Added to handle .bss.
10145 (obj_coff_ident): Added to handle .ident (puts string in .comment

10165 (do_scrub_next_char): For \", return " not '.
10166 (symbol_chars): Now const.
10168 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
10169 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
10171 * config/obj-coff.h: Don't use #elif.
10173 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
10174 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
10176 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
10178 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is
10181 Tue Dec 15 12:40:11 1992 Steve Chamberlain (sac@thepub.cygnus.com)
10183 * app.c (do_scrub_begin): allow single quote strings if so

10190 * read.c (read_a_source_file): avoid calling xmalloc (0).
10192 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)

10196 * Changes to support SCO 3.2v4:
10197 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
10198 SEG_BSS, fill with NOP_OPCODE.
10199 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
10200 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
10201 using ZERO_BASED_SEGMENTS.
10202 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
10203 never set segment address for SEG_E2 (.bss) and don't write out
10204 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
10205 (obj_coff_endef): Don't merge labels or symbols awaiting forward
10206 definitions, and don't merge tags with non-tags. Check for .bf
10207 rather than just checking whether the second character is b and
10208 the third character is f.
10209 (obj_coff_val): gcc can generate values which we don't handle
10210 correctly; discard information for now, since it only affects the
10211 debugging information.
10212 (tag_find_or_name): Don't insert tags in the symbol table.
10213 (yank_symbols): Don't merge labels.
10214 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

10216 set segment address if ZERO_BASED_SEGMENTS.
10217 (obj_coff_section): Accept and ignore a trailing quoted string, as
10218 used in AT&T i386 syntax.

10220 relative addends by the segment vaddr.
10221 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
10222 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
10223 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

10234 power-of-two alignment for .align.
10236 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
10237 and leave everything else alone.

10364 z8000 documentation
10365 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
10368 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
10370 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.
10372 * subsegs.h: add extern to segment_info declaration.
10374 * read.h: added extern declarations for comment_chars,
10375 line_comment_chars, and line_separator_chars.
10376 read.c, app.c: removed definitions of comment_chars,
10377 line_comment_chars, and line_separator_chars.

10396 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
10397 constant will not fit in an immediate field.

10402 * obj-coff.c (callj_table): Delete global variable.
10403 (obj_emit_relocations): Define it locally here, and only if
10404 TC_I960 is defined.
10406 * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.

10435 * Support for i386-sysv.
10436 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
10437 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
10438 be used to set them all to zero as was done before.
10439 (fill_section): segment addresses now set in write_object_file.
10440 (fill_section): Don't set STYP_NOLOAD for .bss section.
10441 (fixup_segment): 386 uses strange common symbol format.

10476 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
10478 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
10479 #elif, since it is not supported by old compilers.
10480 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
10481 couple of expressions in tc-m68k.c.
10483 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10485 * read.c (cons): If NO_RELOC is defined, use it.

10491 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
10492 local labels to start with a .) and set REGISTER_PREFIX to %.
10493 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
10495 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
10497 * messages.c: Comment changes.
10499 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

10502 * messages.c: If __STDC__ is not defined, define NO_STDARG.
10504 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
10506 * listing.c (debugging_pseudo): Add stabs and stabn as things to
10509 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
10511 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
10512 sections starting from zero, rather than making them consecutive.
10513 This makes subsequent reloc calculations easier, esp if the object
10514 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
10515 allocate lcomm in .data rather than in .bss. It seems that some
10516 tools can't cope with a non-zero sized bss before linkage.
10518 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10520 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
10521 throughout. That enum no longer means what we thought it meant.
10523 * tc-m68k.c (md_assemble, md_parse_option): Handle new
10524 "-mno-688[58]1" options.
10526 * tc-m68k.c: Added CPU32 support.
10528 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

10539 * Makefile.in (install): if $(tooldir) exists, install as in
10542 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
10544 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
10545 .word is < -32768 or > 32767. The -J flag causes the error to be
10546 ignored. This is to catch over-sized switches generated by gcc on
10547 systems which don't support the broken .word hack.
10548 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
10549 write.c (fixup_segment): check for signed .word overflow if
10550 WARN_SIGNED_OVERFLOW_WORD.
10552 * write.c (fixup_segment): fixed missing parens in expression
10553 checking for byte or word overflow.
10555 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
10556 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
10557 WARN_SIGNED_OVERFLOW_WORD.

10565 * obj-coffbfd.h : added stuff
10566 * tc-i386.c (tc_coff_fix2rtype): new function
10567 * tc-i386.h : new coff defines
10569 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
10571 * input-scrub.c (input_scrub_push): call input_file_begin, not
10573 messages.c (as_perror): print ": " between the passed in error and
10574 the strerror, like perror does.
10576 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

10583 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
10584 Motorola and MIT syntax; gas can now assemble either type of
10586 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
10587 From Steve Chamberlain:
10588 m68kcoff.mt: for m68k COFF.
10589 obj-coffbfd.c: (fixup_mdeps) added
10590 (size_section) removed bad sanity check
10591 (fill_section) added rs_machine_dependent case
10592 (write_object_file) call fixup_mdeps
10593 (fixup_segment) set fx_subsy to 0.
10594 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
10596 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
10599 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

10622 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
10623 tc-i960.c (md_ri_to_chars): Always output bout object file in
10624 little endian byte order (used to use endianness of host).
10626 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10628 * config/tc-m68k.c (init_table): Now const. Always include 68851
10629 data, so that "bc" is available to 68040 cache instructions.
10630 Added "tt0", "tt1", and 68ec030 variants.
10631 (md_assemble): Complain if 68000 (only) and 68881 are specified.
10632 (enum _register): Added TT0, TT1.
10633 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
10634 line number correctly in "internal error" messages. Don't print
10635 architecture-mismatch message for operand errors.
10637 From Colin Smith (colin@wrs.com):
10638 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
10639 than install_operand.

10648 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
10650 * Makefile.in: defined TARGET_CPU for C code so that it can choose
10651 one element of a family.
10653 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
10655 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
10656 so that we can assemble hand-written libgcc code.
10658 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
10660 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
10661 has already been formatted (but may still contain %-characters).
10662 (as_bad): Likewise.
10664 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
10666 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
10667 written with indirection on the last two operands, which can be
10668 either data or address registers. Added a new operand type 'r'
10669 which accepts either register type. Added '(' to notend stuff in
10670 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
10672 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
10674 * as.h (enum _relax_state): Start off at one, not zero, to better
10675 catch uninitialized-variable errors.
10676 (linkrelax): Declare new variable.
10678 * messages.c (warning_count, error_count): Default initializer is
10681 * write.c: Merged some declarations, using PARMS macro.

10683 data_last_frag): No longer static.
10684 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
10685 defined, call it. Change segments before calling fixup_segment.
10686 (relax_align): If linkrelax, provide extra padding.
10688 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
10689 their not having symbols associated.
10691 * tc-i960.c (norelax, instrument_branches): Default initializer is
10693 (linkrelax): Delete variable definition.

10716 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
10717 being used with args swapped, causing occasional lossage when
10718 refilling buffers after an include file.
10720 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
10722 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
10723 version. Discard bogus DONTDEF version.
10724 (as_warn, as_bad, as_fatal): Likewise.
10726 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
10728 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
10729 selected architecture, print a message saying so and listing what
10730 processors support it, rather than saying "operands mismatch".
10732 Thu Aug 13 13:53:19 1992 Ken Raeburn (raeburn@cygnus.com)

10919 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
10921 * Makefile.in (install): Install into $(tooldir)/bin, since that's
10922 where gcc looks for it.
10924 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
10926 * Makefile.in: Changed some lines to be less confusing for some

10992 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
10994 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
10996 * expr.c (operand): if can't work out what sort of operand it is,
10997 then look through FLT_CHARS for a hint.
10999 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
11001 * Makefile.in, configure.in: removed traces of namesubdir,
11002 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11003 copyrights to '92, changed some from Cygnus to FSF.
11005 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
11006 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
11007 copyrights to '92, changed some from Cygnus to FSF.
11009 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11011 * expr.c: If an expression is single comma, then return with
11012 SEG_ABSENT rather than an error - since the sparc front end does
11013 really strange things with things like fbge,a
11015 * as.h: include bfd.h if using many sections
11016 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
11017 local labels didn't work.
11018 * listing.c (list_symbol_table): don't core dump when there's no
11020 * write.c, write.h: call fix_new with the right number of args on
11022 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
11025 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
11027 * app.c: MRI compatibility - allow single quote to start a string.
11028 * as.c: fix typo recently introduced.
11029 * as.h : Don't include aout/reloc.h - it's not right for COFF!
11030 * expr.c: Much rewriting, to accomodate MRI syntax for
11031 expressions. Also easier to read now.
11032 * listing.c: Put back defuns
11033 * read.c: modified to accept MRI syntax, put back listing pseudo
11034 ops so that an assembler built with NO_LISTING ignores list ops
11036 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
11037 machine is a SPARC or a 29K.
11038 * config/obj-aout.c: added s_sect pseudo op
11039 * config/obj-coffbfd.c: lints, set the filehdr flags right and
11040 fill in the timestamp.
11041 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
11042 anymore, define all the relocs which the tc-<x> bit will use so we
11043 can translate from them to the coff types.
11044 * config/tc-a29k.c: reloc_type isn't ane enum any more
11045 * config/tc-m68k.c: Added NO_RELOC definition.
11047 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
11049 * Makefile.in: put header files before C source for TAGS; remove
11050 references to non-existent syscalls.h.
11052 * read.c, write.c subsegs.c: back out the .bss changes.
11054 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
11056 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
11058 * a.out.h: removed.
11060 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
11062 * symbols.c (local_label_name): symbols now start with ^A.
11064 * read.c, subsegs.c, write.c obj-coff.c: added handling of
11065 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
11066 generate these sections. .align: will use NOP_OPCODE or 0
11067 for padding. This is just for being nice to the
11070 * expr.c (operand): changed to generate local label "\001L0"
11071 starting with a ^A so that it is recognized as a local label.
11073 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
11075 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
11076 i/o opcodes - inb, inw, outb and outw. string manipulation with
11077 att syntax - scmp, slod, smov, ssca, ssto.
11079 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
11080 to just after .file .
11082 In obj_crawl_symbol_chain() where it tries to put the external
11083 symbols apart, with the condition:
11084 (!S_IS_DEFINED(symbolP) &&
11085 !S_IS_DEBUG(symbolP) &&
11086 !SF_GET_STATICS(symbolP))
11087 it was moving too many symbols out. So I switch it back to the
11089 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
11091 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
11092 so that we don't use the F_RELFLG which make the linker complain
11093 that somebody has stripped the relocation info.
11095 Also, the AIX ld program require that the relocation table
11096 is sorted by r_vaddr like the standard ATT assembler does.
11098 [he also changed the sizeof(struct ...)'s into the coff
11099 style FOOSZ macros. I'm not sure this is right, but I can't
11100 remember why. xoxorich.]
11102 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
11104 * Makefile.in, configure.in, doc: use the doc. Build it, install
11107 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
11109 * read.c: white space and comments only.
11111 * configure.in: use the new atof-ns32.c for ns32k.
11113 * write.c: comment change only.
11115 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
11116 aren't yet integrated.
11118 * tc-i860.[hc]: blew off the dust. Something must still be done
11119 about conflicting relocation types.
11121 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
11124 * tc-i960.c, tc-sparc.c: white space and comments only.
11126 * tc-a29k.h: delete duplicate macro definition.
11128 * new file atof-ns32k.c copied from hack's last unreleased gas.
11130 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
11132 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
11135 * nearly everything. flush ChangeLog, package as gas-1.92.1.
11136 ChangeLog's prior to this are sketchy at best. I have logs.
11137 They just aren't ChangeLogs.
