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

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

961 against placing additional object-file dependent code here. Warn
962 against contaminating all of GAS with the internals of tc-hppa.c
963 through inclusion of tc-hppa.h. Delete all forward declarations
964 for functions only used within tc-hppa.c, likewise for structures,
965 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
966 conditional code in a few small places.
968 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
969 structures, global variables, forward declarations together.

971 conditional code -- try to group conditional code together
972 into a few places. Make all functions and variables which
973 are only used within tc-hppa.c static. PARAMize all functions.
974 Add comments to functions. Delete unused functions, variables,
975 #defines, etc. Delete unused members within structures. Delete
976 ldil;ble hacks -- it is believed they were installed to work
977 around old gas bugs. Avoid using mixed case for local
978 functions, variables, and structures. Fix formatting problems

2124 * Extensive changes to permit symbols to contain any expression
2125 type and to delay the computation of the expression until the
2126 value is actually needed. This permits setting symbols to values
2127 calculated based on object code size. Expressions were changed to
2128 no longer be in a section, to stop the overloading of segment and
2129 expression type that previously occurred.
2131 * as.c (big_section, pass1_section, diff_section, absent_section):

2243 calculating opP->isiz; this permits the expression size to be
2244 determined as well, later on.

3451 avoid some redefinition complaints on some systems.
3452 (const, volatile): Don't need these conditionally defined if we
3453 use CONST and VOLATILE from ansidecl.h.
3454 (seg_name): Use CONST, not const.
3456 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3458 * config/tc-mips.c: Reindented to GNU standards.

3469 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3471 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3491 * Makefile.in (targ-cpu.o): Depend on config.h.
3493 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3495 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3496 dropping a space immediately following an identifier.
3497 * expr.c, write.c: Rewrote assert expressions to not use multiple
3498 lines; I don't think that can be done portably.
3499 * config/tc-mips.c (macro): Use $AT if target register is zero in
3500 load instruction, which it can be for a floating point load.
3502 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3523 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3525 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3526 to be on a single line.

3574 prototypes for all static functions. Moved existing minimal
3575 debugging format support info #ifndef OBJ_ECOFF blocks.

3579 (tc_get_register): Renamed from get_register, and made non-static.
3581 * config/mips-big.mt, config/mips-lit.mt: New files. Define

3624 * make-gas.com: Find obstack.obj if it's not in the current
3626 * read.c (s_ignore): Don't declare is_end_of_line. It's
3627 redundant, and triggers a VMS gcc compiler bug.
3629 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3630 current segment as an argument. (Ignored in all cases but VMS.)
3631 All callers and definitions changed.

3928 md_relax_table): Use default zero initialization.
3929 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3930 latter, instead of selecting with preprocessor conditionals.
3932 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3934 * configure.in: recognise all sparclite variants

3944 * expr.c (operand): If character other than comma or newline is a
3945 logical end-of-line character, use the newline case.
3946 From Eric Youngdale:
3947 (operand): Set X_add_number field for floating-point numbers.
3948 (operand): Treat zero byte as end-of-operand.
3950 * configure.in (per-target): Look for with_bfd_assembler option.
3951 For now, only accept "no", until the merge is done.
3953 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3954 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

3960 * expr.c: Add "const" modifier to hex_value.
3961 * symbols.c: Finish conversion to S_* macros in the VMS only
3962 parts of the program. Add "const" modifier to
3963 md_[long,short]_jump_size. Remove declaration of const_flag
3964 (which will be declared in obj-vms.h).
3965 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3966 Fix arguments to VMS_write_object_file.
3967 * config-gas.com: New file. Script for VMS systems to set up the
3968 configuration to build gas for VMS, and create config.status.
3969 * make-gas.com: Redone to work with new scheme.
3970 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3972 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

3975 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3976 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3977 types of malformed stabs. Change parsing algorithm so that we are
3978 more certain of having all of the information that we need on hand.
3979 * obj-vms.c (final_forward_reference): New function, used to help
3980 resolve the data types of as many struct elements as possible
3981 when some part of the struct is not fully defined by the compiler.

3984 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3985 as symbols as well in the object file. Look for external functions

3987 g++ compiler is incapable of doing this.
3988 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3990 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3991 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3992 have the name of the source file yet.
3993 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3995 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3997 * read.c (s_data): Always use "data_section", since it'll map to
3998 SEG_DATA or SEG_E1 if needed.
3999 (s_lcomm): Likewise with bss_section.
4000 (s_fill): Use memset, not bzero.
4002 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4024 (big_section, reg_section, pass1_section, diff_section,
4025 absent_section, text_section, data_section, bss_section): If
4026 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4027 mapping to segT enum values.
4028 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4029 if these are used or defined, if BFD_ASSEMBLER.
4030 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4031 subseg_new split into two functions.
4032 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4034 * as.h (volatile): Don't define if already defined.
4035 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4037 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4038 declare with format attribute for -Wformat checking.
4040 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4042 * app.c, config/tc-*.c: Don't include read.h, since it is already
4045 * These are based on patches from Minh Tran-le
4046 <mtranle@paris.intellicorp.com>.
4047 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4048 obj_format coffbfd and gas_target i386coff for target.
4049 (i[34]86-*-isc*): New host (uses sysv).
4050 * config/i386aix.mt: Removed (no longer used).
4051 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4053 (LDFLAGS): Added, defined as -shlib.
4054 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4055 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4056 (DOT_LABEL_PREFIX): Define.

4070 (size_section): Restored sanity check.
4071 (do_relocs_for): Base section address on s_paddr rather than
4072 computing it. Adjust a29k R_IHIHALF special case to account for
4073 section paddr (used to require paddr to be zero). If there are no
4074 reclos, set s_relptr to 0. Set relocation size in object_headers.
4075 (fill_section): Always set s_vaddr here, removing
4076 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4077 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4078 Set STYP_INFO for .comment.
4079 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4080 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4082 H_{SET,GET}_* macros.
4083 (do_linenos_for): Set lineno size in object_headers.
4084 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4085 set s_vaddr here. If string_byte_count remains 4, set it back to
4086 0, and only write strings out if there are some. Call
4087 fill_section before do_relocs_for and do_linenos_for.
4088 (obj_coff_section): Handle optional quoted second argument giving
4089 section characteristics.
4090 (obj_coff_bss): Added to handle .bss.
4091 (obj_coff_ident): Added to handle .ident (puts string in .comment

4111 (do_scrub_next_char): For \", return " not '.
4112 (symbol_chars): Now const.
4114 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4115 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4117 * config/obj-coff.h: Don't use #elif.
4119 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4120 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4122 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4124 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4144 SEG_BSS, fill with NOP_OPCODE.
4145 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4146 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4147 using ZERO_BASED_SEGMENTS.
4148 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4149 never set segment address for SEG_E2 (.bss) and don't write out
4150 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4151 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4152 definitions, and don't merge tags with non-tags. Check for .bf
4153 rather than just checking whether the second character is b and
4154 the third character is f.
4155 (obj_coff_val): gcc can generate values which we don't handle
4156 correctly; discard information for now, since it only affects the
4157 debugging information.
4158 (tag_find_or_name): Don't insert tags in the symbol table.
4159 (yank_symbols): Don't merge labels.
4160 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4215 options. Updated options documentation for m68k. Some minor
4216 wording/punctuation changes.
4218 Mon Nov 30 11:42:11 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4220 * configure.in: Accept target OS "vms".

4306 could be doing emulation.
4308 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4311 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4381 * Support for i386-sysv.
4382 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4422 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4424 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4425 #elif, since it is not supported by old compilers.
4426 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4427 couple of expressions in tc-m68k.c.
4429 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4431 * read.c (cons): If NO_RELOC is defined, use it.

4435 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4437 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require

4455 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4457 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4458 sections starting from zero, rather than making them consecutive.
4459 This makes subsequent reloc calculations easier, esp if the object
4460 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4461 allocate lcomm in .data rather than in .bss. It seems that some
4462 tools can't cope with a non-zero sized bss before linkage.
4464 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4466 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4483 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4485 * Makefile.in (install): if $(tooldir) exists, install as in
4488 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4490 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4491 .word is < -32768 or > 32767. The -J flag causes the error to be
4492 ignored. This is to catch over-sized switches generated by gcc on
4493 systems which don't support the broken .word hack.
4494 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4495 write.c (fixup_segment): check for signed .word overflow if
4496 WARN_SIGNED_OVERFLOW_WORD.
4498 * write.c (fixup_segment): fixed missing parens in expression
4499 checking for byte or word overflow.

4515 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4517 * input-scrub.c (input_scrub_push): call input_file_begin, not
4519 messages.c (as_perror): print ": " between the passed in error and
4520 the strerror, like perror does.
4522 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

4525 From Steve Chamberlain:
4526 Makefile.in: Handle m68*-*-coff*.
4527 read.c, read.h: add mult argument to s_space
4529 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4530 Motorola and MIT syntax; gas can now assemble either type of
4532 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4539 (fixup_segment) set fx_subsy to 0.
4540 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4542 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4545 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4547 * Makefile.in (LIBS): Include opcode library.

4570 little endian byte order (used to use endianness of host).
4572 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4574 * config/tc-m68k.c (init_table): Now const. Always include 68851
4575 data, so that "bc" is available to 68040 cache instructions.
4576 Added "tt0", "tt1", and 68ec030 variants.
4577 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4578 (enum _register): Added TT0, TT1.
4579 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4580 line number correctly in "internal error" messages. Don't print
4581 architecture-mismatch message for operand errors.
4583 From Colin Smith (colin@wrs.com):
4584 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4585 than install_operand.

4599 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
4601 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4602 so that we can assemble hand-written libgcc code.

4606 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4607 has already been formatted (but may still contain %-characters).
4610 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4612 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4613 written with indirection on the last two operands, which can be
4614 either data or address registers. Added a new operand type 'r'
4615 which accepts either register type. Added '(' to notend stuff in
4616 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4618 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

4634 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4635 their not having symbols associated.
4637 * tc-i960.c (norelax, instrument_branches): Default initializer is
4639 (linkrelax): Delete variable definition.

4662 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
4663 being used with args swapped, causing occasional lossage when
4664 refilling buffers after an include file.
4666 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
4668 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
4669 version. Discard bogus DONTDEF version.
4670 (as_warn, as_bad, as_fatal): Likewise.
4672 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
4674 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
4675 selected architecture, print a message saying so and listing what

4716 fx_offset into account.
4718 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
4720 * configure.in (mips host): Accept "ultrix" with version number.
4722 * expr.c (floating_constant): Separate "=-" to avoid confusing
4723 ancient or broken compilers.
4725 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
4726 processor/opcode mismatch, so reword the error message.
4727 (md_assemble): If no CPU has been set (even if FPU/PMMU

4865 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4867 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4868 where gcc looks for it.

4938 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4940 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4942 * expr.c (operand): if can't work out what sort of operand it is,
4943 then look through FLT_CHARS for a hint.
4945 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4947 * Makefile.in, configure.in: removed traces of namesubdir,

4951 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4952 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4953 copyrights to '92, changed some from Cygnus to FSF.
4955 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4957 * expr.c: If an expression is single comma, then return with
4958 SEG_ABSENT rather than an error - since the sparc front end does
4959 really strange things with things like fbge,a
4961 * as.h: include bfd.h if using many sections
4962 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4963 local labels didn't work.
4964 * listing.c (list_symbol_table): don't core dump when there's no
4966 * write.c, write.h: call fix_new with the right number of args on

4971 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4973 * app.c: MRI compatibility - allow single quote to start a string.
4974 * as.c: fix typo recently introduced.
4975 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4976 * expr.c: Much rewriting, to accomodate MRI syntax for
4977 expressions. Also easier to read now.
4978 * listing.c: Put back defuns
4979 * read.c: modified to accept MRI syntax, put back listing pseudo
4980 ops so that an assembler built with NO_LISTING ignores list ops
4982 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4983 machine is a SPARC or a 29K.
4984 * config/obj-aout.c: added s_sect pseudo op
4985 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4986 fill in the timestamp.
4987 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4988 anymore, define all the relocs which the tc-<x> bit will use so we
4989 can translate from them to the coff types.
4990 * config/tc-a29k.c: reloc_type isn't ane enum any more
4991 * config/tc-m68k.c: Added NO_RELOC definition.
4993 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4995 * Makefile.in: put header files before C source for TAGS; remove
4996 references to non-existent syscalls.h.
4998 * read.c, write.c subsegs.c: back out the .bss changes.
5000 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5002 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5006 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5008 * symbols.c (local_label_name): symbols now start with ^A.
5010 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5011 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5012 generate these sections. .align: will use NOP_OPCODE or 0
5013 for padding. This is just for being nice to the
5016 * expr.c (operand): changed to generate local label "\001L0"
5017 starting with a ^A so that it is recognized as a local label.
5019 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5021 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5022 i/o opcodes - inb, inw, outb and outw. string manipulation with
5023 att syntax - scmp, slod, smov, ssca, ssto.
5025 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5026 to just after .file .
5028 In obj_crawl_symbol_chain() where it tries to put the external
5029 symbols apart, with the condition:
5030 (!S_IS_DEFINED(symbolP) &&
5031 !S_IS_DEBUG(symbolP) &&
5032 !SF_GET_STATICS(symbolP))
5033 it was moving too many symbols out. So I switch it back to the
5035 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5037 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5038 so that we don't use the F_RELFLG which make the linker complain
5039 that somebody has stripped the relocation info.
5041 Also, the AIX ld program require that the relocation table
5042 is sorted by r_vaddr like the standard ATT assembler does.
5044 [he also changed the sizeof(struct ...)'s into the coff
5045 style FOOSZ macros. I'm not sure this is right, but I can't
5046 remember why. xoxorich.]
5048 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5050 * Makefile.in, configure.in, doc: use the doc. Build it, install

5055 * read.c: white space and comments only.
5057 * configure.in: use the new atof-ns32.c for ns32k.
5059 * write.c: comment change only.
5061 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5062 aren't yet integrated.
5064 * tc-i860.[hc]: blew off the dust. Something must still be done
5065 about conflicting relocation types.
5067 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5070 * tc-i960.c, tc-sparc.c: white space and comments only.
5072 * tc-a29k.h: delete duplicate macro definition.
5074 * new file atof-ns32k.c copied from hack's last unreleased gas.
5076 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5078 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5081 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5082 ChangeLog's prior to this are sketchy at best. I have logs.
5083 They just aren't ChangeLogs.
