983 for functions only used within tc-hppa.c, likewise for structures,
984 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
985 conditional code in a few small places.
987 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
988 structures, global variables, forward declarations together.
989 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
990 conditional code -- try to group conditional code together
991 into a few places. Make all functions and variables which
992 are only used within tc-hppa.c static. PARAMize all functions.
993 Add comments to functions. Delete unused functions, variables,
994 #defines, etc. Delete unused members within structures. Delete
995 ldil;ble hacks -- it is believed they were installed to work
996 around old gas bugs. Avoid using mixed case for local
997 functions, variables, and structures. Fix formatting problems
998 not found by GNU-indent. Add FIXME notices for things which
999 should be worked on the near future. Delete lots of old
1000 useless (1.36 PA-SOM) code.

2143 * Extensive changes to permit symbols to contain any expression
2144 type and to delay the computation of the expression until the
2145 value is actually needed. This permits setting symbols to values
2146 calculated based on object code size. Expressions were changed to
2147 no longer be in a section, to stop the overloading of segment and
2148 expression type that previously occurred.
2150 * as.c (big_section, pass1_section, diff_section, absent_section):
2152 (expr_section): Added (used for dummy symbols which hold

2261 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
2262 calculating opP->isiz; this permits the expression size to be
2263 determined as well, later on.

2277 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
2279 * read.c (float_cons): Simplified parsing logic. If
2280 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

3442 source directory, if that's not the current directory.
3444 * configure.in (per-host): Accept MIPS host with BSD version

3470 avoid some redefinition complaints on some systems.
3471 (const, volatile): Don't need these conditionally defined if we
3472 use CONST and VOLATILE from ansidecl.h.
3473 (seg_name): Use CONST, not const.
3475 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3477 * config/tc-mips.c: Reindented to GNU standards.

3481 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3482 (fixup_segment): Add a29k special case; the linker is not prepared
3483 to see a segment offset here.
3485 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3488 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3490 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3491 srcdir, might be in objdir.

3510 * Makefile.in (targ-cpu.o): Depend on config.h.
3512 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3514 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3515 dropping a space immediately following an identifier.
3516 * expr.c, write.c: Rewrote assert expressions to not use multiple
3517 lines; I don't think that can be done portably.
3518 * config/tc-mips.c (macro): Use $AT if target register is zero in
3519 load instruction, which it can be for a floating point load.
3521 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3535 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
3538 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

3542 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3544 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3545 to be on a single line.

3593 prototypes for all static functions. Moved existing minimal
3594 debugging format support info #ifndef OBJ_ECOFF blocks.

3643 * make-gas.com: Find obstack.obj if it's not in the current
3645 * read.c (s_ignore): Don't declare is_end_of_line. It's
3646 redundant, and triggers a VMS gcc compiler bug.
3648 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3649 current segment as an argument. (Ignored in all cases but VMS.)
3650 All callers and definitions changed.

3947 md_relax_table): Use default zero initialization.
3948 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3949 latter, instead of selecting with preprocessor conditionals.
3951 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3953 * configure.in: recognise all sparclite variants

3963 * expr.c (operand): If character other than comma or newline is a
3964 logical end-of-line character, use the newline case.
3965 From Eric Youngdale:
3966 (operand): Set X_add_number field for floating-point numbers.
3967 (operand): Treat zero byte as end-of-operand.
3969 * configure.in (per-target): Look for with_bfd_assembler option.
3970 For now, only accept "no", until the merge is done.
3972 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3973 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

3979 * expr.c: Add "const" modifier to hex_value.
3980 * symbols.c: Finish conversion to S_* macros in the VMS only
3981 parts of the program. Add "const" modifier to
3982 md_[long,short]_jump_size. Remove declaration of const_flag
3983 (which will be declared in obj-vms.h).
3984 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3985 Fix arguments to VMS_write_object_file.
3986 * config-gas.com: New file. Script for VMS systems to set up the
3987 configuration to build gas for VMS, and create config.status.
3988 * make-gas.com: Redone to work with new scheme.
3989 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3991 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

3994 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3995 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3996 types of malformed stabs. Change parsing algorithm so that we are
3997 more certain of having all of the information that we need on hand.
3998 * obj-vms.c (final_forward_reference): New function, used to help
3999 resolve the data types of as many struct elements as possible
4000 when some part of the struct is not fully defined by the compiler.

4003 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4004 as symbols as well in the object file. Look for external functions
4005 that start with "__vt.", and turn them into variables, since the
4006 g++ compiler is incapable of doing this.
4007 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4009 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4010 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4011 have the name of the source file yet.
4012 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4014 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4016 * read.c (s_data): Always use "data_section", since it'll map to
4017 SEG_DATA or SEG_E1 if needed.
4018 (s_lcomm): Likewise with bss_section.
4019 (s_fill): Use memset, not bzero.
4021 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4043 (big_section, reg_section, pass1_section, diff_section,
4044 absent_section, text_section, data_section, bss_section): If
4045 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4046 mapping to segT enum values.
4047 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4048 if these are used or defined, if BFD_ASSEMBLER.
4049 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4050 subseg_new split into two functions.
4051 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4053 * as.h (volatile): Don't define if already defined.
4054 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4056 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4057 declare with format attribute for -Wformat checking.
4059 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4061 * app.c, config/tc-*.c: Don't include read.h, since it is already
4064 * These are based on patches from Minh Tran-le
4065 <mtranle@paris.intellicorp.com>.
4066 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4067 obj_format coffbfd and gas_target i386coff for target.
4068 (i[34]86-*-isc*): New host (uses sysv).
4069 * config/i386aix.mt: Removed (no longer used).
4070 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4072 (LDFLAGS): Added, defined as -shlib.
4073 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4074 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4075 (DOT_LABEL_PREFIX): Define.
4076 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4077 name rather than L0\001.
4078 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4080 * symbols.c, symbols.h (local_bss_counter): Removed.

4089 (size_section): Restored sanity check.
4090 (do_relocs_for): Base section address on s_paddr rather than
4091 computing it. Adjust a29k R_IHIHALF special case to account for
4092 section paddr (used to require paddr to be zero). If there are no
4093 reclos, set s_relptr to 0. Set relocation size in object_headers.
4094 (fill_section): Always set s_vaddr here, removing
4095 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4096 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4097 Set STYP_INFO for .comment.
4098 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4099 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4101 H_{SET,GET}_* macros.
4102 (do_linenos_for): Set lineno size in object_headers.
4103 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4104 set s_vaddr here. If string_byte_count remains 4, set it back to
4105 0, and only write strings out if there are some. Call
4106 fill_section before do_relocs_for and do_linenos_for.
4107 (obj_coff_section): Handle optional quoted second argument giving
4108 section characteristics.
4109 (obj_coff_bss): Added to handle .bss.
4110 (obj_coff_ident): Added to handle .ident (puts string in .comment

4130 (do_scrub_next_char): For \", return " not '.
4131 (symbol_chars): Now const.
4133 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4134 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4136 * config/obj-coff.h: Don't use #elif.
4138 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4139 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4141 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4143 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4163 SEG_BSS, fill with NOP_OPCODE.
4164 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4165 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4166 using ZERO_BASED_SEGMENTS.
4167 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4168 never set segment address for SEG_E2 (.bss) and don't write out
4169 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4170 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4171 definitions, and don't merge tags with non-tags. Check for .bf
4172 rather than just checking whether the second character is b and
4173 the third character is f.
4174 (obj_coff_val): gcc can generate values which we don't handle
4175 correctly; discard information for now, since it only affects the
4176 debugging information.
4177 (tag_find_or_name): Don't insert tags in the symbol table.
4178 (yank_symbols): Don't merge labels.
4179 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4199 power-of-two alignment for .align.
4201 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
4202 and leave everything else alone.

4325 could be doing emulation.
4327 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4330 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4359 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4361 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4362 constant will not fit in an immediate field.
4363 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4400 * Support for i386-sysv.
4401 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4443 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4444 #elif, since it is not supported by old compilers.
4445 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4446 couple of expressions in tc-m68k.c.
4448 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4450 * read.c (cons): If NO_RELOC is defined, use it.
4452 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4454 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4456 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4457 local labels to start with a .) and set REGISTER_PREFIX to %.
4458 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4474 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4476 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4477 sections starting from zero, rather than making them consecutive.
4478 This makes subsequent reloc calculations easier, esp if the object
4479 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4480 allocate lcomm in .data rather than in .bss. It seems that some
4481 tools can't cope with a non-zero sized bss before linkage.
4483 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4485 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4504 * Makefile.in (install): if $(tooldir) exists, install as in
4507 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4509 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4510 .word is < -32768 or > 32767. The -J flag causes the error to be
4511 ignored. This is to catch over-sized switches generated by gcc on
4512 systems which don't support the broken .word hack.
4513 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4514 write.c (fixup_segment): check for signed .word overflow if
4515 WARN_SIGNED_OVERFLOW_WORD.
4517 * write.c (fixup_segment): fixed missing parens in expression
4518 checking for byte or word overflow.

4534 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4536 * input-scrub.c (input_scrub_push): call input_file_begin, not
4538 messages.c (as_perror): print ": " between the passed in error and
4539 the strerror, like perror does.

4544 From Steve Chamberlain:
4545 Makefile.in: Handle m68*-*-coff*.
4546 read.c, read.h: add mult argument to s_space
4548 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4549 Motorola and MIT syntax; gas can now assemble either type of
4551 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4558 (fixup_segment) set fx_subsy to 0.
4559 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4561 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4564 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4566 * Makefile.in (LIBS): Include opcode library.

4591 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4593 * config/tc-m68k.c (init_table): Now const. Always include 68851
4594 data, so that "bc" is available to 68040 cache instructions.
4595 Added "tt0", "tt1", and 68ec030 variants.
4596 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4597 (enum _register): Added TT0, TT1.
4598 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4599 line number correctly in "internal error" messages. Don't print
4600 architecture-mismatch message for operand errors.
4602 From Colin Smith (colin@wrs.com):
4603 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4604 than install_operand.

4620 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4621 so that we can assemble hand-written libgcc code.

4625 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4626 has already been formatted (but may still contain %-characters).
4629 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4631 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4632 written with indirection on the last two operands, which can be
4633 either data or address registers. Added a new operand type 'r'
4634 which accepts either register type. Added '(' to notend stuff in
4635 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4637 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

4653 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4654 their not having symbols associated.
4656 * tc-i960.c (norelax, instrument_branches): Default initializer is
4658 (linkrelax): Delete variable definition.

4682 being used with args swapped, causing occasional lossage when
4683 refilling buffers after an include file.

4687 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
4688 version. Discard bogus DONTDEF version.

4691 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
4693 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
4694 selected architecture, print a message saying so and listing what

4832 * write.c (write_object_file): keep the fix_tail clean, which
4833 fixes a bug in -R where relocations were being lost.
4835 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4837 * configure.in: recognize m680x0 as having sun3 emulation mode for

4882 start addresses to match required alignment.
4884 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4886 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4887 where gcc looks for it.
4889 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4891 * Makefile.in: Changed some lines to be less confusing for some

4957 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4959 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4961 * expr.c (operand): if can't work out what sort of operand it is,
4962 then look through FLT_CHARS for a hint.
4964 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4966 * Makefile.in, configure.in: removed traces of namesubdir,

4968 copyrights to '92, changed some from Cygnus to FSF.
4970 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4971 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4972 copyrights to '92, changed some from Cygnus to FSF.
4974 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4976 * expr.c: If an expression is single comma, then return with
4977 SEG_ABSENT rather than an error - since the sparc front end does
4978 really strange things with things like fbge,a
4980 * as.h: include bfd.h if using many sections
4981 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4982 local labels didn't work.
4983 * listing.c (list_symbol_table): don't core dump when there's no
4985 * write.c, write.h: call fix_new with the right number of args on
4987 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4990 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4992 * app.c: MRI compatibility - allow single quote to start a string.
4993 * as.c: fix typo recently introduced.
4994 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4995 * expr.c: Much rewriting, to accomodate MRI syntax for
4996 expressions. Also easier to read now.
4997 * listing.c: Put back defuns
4998 * read.c: modified to accept MRI syntax, put back listing pseudo
4999 ops so that an assembler built with NO_LISTING ignores list ops
5001 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5002 machine is a SPARC or a 29K.
5003 * config/obj-aout.c: added s_sect pseudo op
5004 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5005 fill in the timestamp.
5006 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5007 anymore, define all the relocs which the tc-<x> bit will use so we
5008 can translate from them to the coff types.
5009 * config/tc-a29k.c: reloc_type isn't ane enum any more
5010 * config/tc-m68k.c: Added NO_RELOC definition.
5012 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5014 * Makefile.in: put header files before C source for TAGS; remove
5015 references to non-existent syscalls.h.
5017 * read.c, write.c subsegs.c: back out the .bss changes.
5019 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5021 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5025 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5027 * symbols.c (local_label_name): symbols now start with ^A.
5029 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5030 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5031 generate these sections. .align: will use NOP_OPCODE or 0
5032 for padding. This is just for being nice to the
5035 * expr.c (operand): changed to generate local label "\001L0"
5036 starting with a ^A so that it is recognized as a local label.
5038 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5040 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5041 i/o opcodes - inb, inw, outb and outw. string manipulation with
5042 att syntax - scmp, slod, smov, ssca, ssto.
5044 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5045 to just after .file .
5047 In obj_crawl_symbol_chain() where it tries to put the external
5048 symbols apart, with the condition:
5049 (!S_IS_DEFINED(symbolP) &&
5050 !S_IS_DEBUG(symbolP) &&
5051 !SF_GET_STATICS(symbolP))
5052 it was moving too many symbols out. So I switch it back to the
5054 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5056 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5057 so that we don't use the F_RELFLG which make the linker complain
5058 that somebody has stripped the relocation info.
5060 Also, the AIX ld program require that the relocation table
5061 is sorted by r_vaddr like the standard ATT assembler does.
5063 [he also changed the sizeof(struct ...)'s into the coff
5064 style FOOSZ macros. I'm not sure this is right, but I can't
5065 remember why. xoxorich.]
5067 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5069 * Makefile.in, configure.in, doc: use the doc. Build it, install
5072 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5074 * read.c: white space and comments only.
5076 * configure.in: use the new atof-ns32.c for ns32k.
5078 * write.c: comment change only.
5080 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5081 aren't yet integrated.
5083 * tc-i860.[hc]: blew off the dust. Something must still be done
5084 about conflicting relocation types.
5086 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5089 * tc-i960.c, tc-sparc.c: white space and comments only.
5091 * tc-a29k.h: delete duplicate macro definition.
5093 * new file atof-ns32k.c copied from hack's last unreleased gas.
5095 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5097 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5100 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5101 ChangeLog's prior to this are sketchy at best. I have logs.
5102 They just aren't ChangeLogs.
