1434 i386) as developmental. Deleted cases matching some generic names
1435 in favor of more specific names. (E.g., when we get Alpha

1463 Add comments to functions. Delete unused functions, variables,
1464 #defines, etc. Delete unused members within structures. Delete
1465 ldil;ble hacks -- it is believed they were installed to work
1466 around old gas bugs. Avoid using mixed case for local
1467 functions, variables, and structures. Fix formatting problems

2613 * Extensive changes to permit symbols to contain any expression
2614 type and to delay the computation of the expression until the
2615 value is actually needed. This permits setting symbols to values
2616 calculated based on object code size. Expressions were changed to
2617 no longer be in a section, to stop the overloading of segment and
2618 expression type that previously occurred.
2620 * as.c (big_section, pass1_section, diff_section, absent_section):
2622 (expr_section): Added (used for dummy symbols which hold

2708 to pop back to it. Handle unquoted section name as well as quoted
2709 section name. Don't crash on invalid strings.

2731 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
2732 calculating opP->isiz; this permits the expression size to be
2733 determined as well, later on.
2735 * expr.c (clean_up_expression): Don't cancel the subtraction of
2738 * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

2747 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
2749 * read.c (float_cons): Simplified parsing logic. If
2750 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
2752 * symbols.c (colon): Rather than a special case for TC_HPPA,
2753 use new macro tc_frob_label.
2754 * config/tc-hppa.h (tc_frob_label): Define.
2756 * config/tc-mips.c: Many changes to support simple assembler

2770 (macro): Call mips_emit_delays before setting mips_noreorder.
2771 Increment and decrement mips_noreorder rather than using

3940 avoid some redefinition complaints on some systems.
3941 (const, volatile): Don't need these conditionally defined if we
3942 use CONST and VOLATILE from ansidecl.h.
3943 (seg_name): Use CONST, not const.

3958 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3960 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3980 * Makefile.in (targ-cpu.o): Depend on config.h.
3982 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3984 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3985 dropping a space immediately following an identifier.

3987 lines; I don't think that can be done portably.
3988 * config/tc-mips.c (macro): Use $AT if target register is zero in
3989 load instruction, which it can be for a floating point load.
3991 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4012 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4014 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4015 to be on a single line.

4063 prototypes for all static functions. Moved existing minimal
4064 debugging format support info #ifndef OBJ_ECOFF blocks.

4113 * make-gas.com: Find obstack.obj if it's not in the current
4115 * read.c (s_ignore): Don't declare is_end_of_line. It's
4116 redundant, and triggers a VMS gcc compiler bug.
4118 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4119 current segment as an argument. (Ignored in all cases but VMS.)
4120 All callers and definitions changed.

4417 md_relax_table): Use default zero initialization.
4418 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4419 latter, instead of selecting with preprocessor conditionals.
4421 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4423 * configure.in: recognise all sparclite variants

4433 * expr.c (operand): If character other than comma or newline is a
4434 logical end-of-line character, use the newline case.
4435 From Eric Youngdale:
4436 (operand): Set X_add_number field for floating-point numbers.
4437 (operand): Treat zero byte as end-of-operand.
4439 * configure.in (per-target): Look for with_bfd_assembler option.
4440 For now, only accept "no", until the merge is done.
4442 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4443 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4444 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4445 * read.c: Finish conversion to S_* macros in the VMS only
4446 parts of the program. Add "const" modifier to hex_value.
4447 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4449 * expr.c: Add "const" modifier to hex_value.
4450 * symbols.c: Finish conversion to S_* macros in the VMS only
4451 parts of the program. Add "const" modifier to
4452 md_[long,short]_jump_size. Remove declaration of const_flag
4453 (which will be declared in obj-vms.h).
4454 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4455 Fix arguments to VMS_write_object_file.
4456 * config-gas.com: New file. Script for VMS systems to set up the
4457 configuration to build gas for VMS, and create config.status.
4458 * make-gas.com: Redone to work with new scheme.
4459 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4461 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4462 will swap bytes if needed on a big endian system. Use throughout
4464 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4465 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4466 types of malformed stabs. Change parsing algorithm so that we are
4467 more certain of having all of the information that we need on hand.
4468 * obj-vms.c (final_forward_reference): New function, used to help
4469 resolve the data types of as many struct elements as possible
4470 when some part of the struct is not fully defined by the compiler.

4473 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4474 as symbols as well in the object file. Look for external functions
4475 that start with "__vt.", and turn them into variables, since the
4476 g++ compiler is incapable of doing this.
4477 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4479 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4480 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4481 have the name of the source file yet.
4482 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4484 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4486 * read.c (s_data): Always use "data_section", since it'll map to
4487 SEG_DATA or SEG_E1 if needed.
4488 (s_lcomm): Likewise with bss_section.
4489 (s_fill): Use memset, not bzero.
4491 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4513 (big_section, reg_section, pass1_section, diff_section,
4514 absent_section, text_section, data_section, bss_section): If
4515 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4516 mapping to segT enum values.
4517 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4518 if these are used or defined, if BFD_ASSEMBLER.
4519 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4520 subseg_new split into two functions.
4521 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4523 * as.h (volatile): Don't define if already defined.
4524 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4526 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4527 declare with format attribute for -Wformat checking.
4529 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4531 * app.c, config/tc-*.c: Don't include read.h, since it is already
4534 * These are based on patches from Minh Tran-le
4535 <mtranle@paris.intellicorp.com>.
4536 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4537 obj_format coffbfd and gas_target i386coff for target.
4538 (i[34]86-*-isc*): New host (uses sysv).
4539 * config/i386aix.mt: Removed (no longer used).
4540 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4542 (LDFLAGS): Added, defined as -shlib.
4543 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4544 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4545 (DOT_LABEL_PREFIX): Define.
4546 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4547 name rather than L0\001.
4548 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4550 * symbols.c, symbols.h (local_bss_counter): Removed.
4551 * write.c (write_object_file): bss no longer uses

4559 (size_section): Restored sanity check.
4560 (do_relocs_for): Base section address on s_paddr rather than
4561 computing it. Adjust a29k R_IHIHALF special case to account for
4562 section paddr (used to require paddr to be zero). If there are no
4563 reclos, set s_relptr to 0. Set relocation size in object_headers.
4564 (fill_section): Always set s_vaddr here, removing
4565 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4566 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4567 Set STYP_INFO for .comment.
4568 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4569 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4571 H_{SET,GET}_* macros.
4572 (do_linenos_for): Set lineno size in object_headers.
4573 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4574 set s_vaddr here. If string_byte_count remains 4, set it back to
4575 0, and only write strings out if there are some. Call
4576 fill_section before do_relocs_for and do_linenos_for.
4577 (obj_coff_section): Handle optional quoted second argument giving
4578 section characteristics.
4579 (obj_coff_bss): Added to handle .bss.
4580 (obj_coff_ident): Added to handle .ident (puts string in .comment

4600 (do_scrub_next_char): For \", return " not '.
4601 (symbol_chars): Now const.
4603 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4604 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4606 * config/obj-coff.h: Don't use #elif.
4608 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4609 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4611 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4613 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4633 SEG_BSS, fill with NOP_OPCODE.
4634 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4635 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4636 using ZERO_BASED_SEGMENTS.
4637 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4638 never set segment address for SEG_E2 (.bss) and don't write out
4639 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4640 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4641 definitions, and don't merge tags with non-tags. Check for .bf
4642 rather than just checking whether the second character is b and
4643 the third character is f.
4644 (obj_coff_val): gcc can generate values which we don't handle
4645 correctly; discard information for now, since it only affects the
4646 debugging information.
4647 (tag_find_or_name): Don't insert tags in the symbol table.
4648 (yank_symbols): Don't merge labels.
4649 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4669 power-of-two alignment for .align.
4671 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
4672 and leave everything else alone.

4795 could be doing emulation.
4797 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4800 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4829 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4831 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4832 constant will not fit in an immediate field.
4833 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4868 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4870 * Support for i386-sysv.
4871 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4911 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4913 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4914 #elif, since it is not supported by old compilers.
4915 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4916 couple of expressions in tc-m68k.c.
4918 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4920 * read.c (cons): If NO_RELOC is defined, use it.
4922 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4924 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4926 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4927 local labels to start with a .) and set REGISTER_PREFIX to %.
4928 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4930 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4944 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4946 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4947 sections starting from zero, rather than making them consecutive.
4948 This makes subsequent reloc calculations easier, esp if the object
4949 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4950 allocate lcomm in .data rather than in .bss. It seems that some
4951 tools can't cope with a non-zero sized bss before linkage.
4953 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4955 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4974 * Makefile.in (install): if $(tooldir) exists, install as in
4977 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4979 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4980 .word is < -32768 or > 32767. The -J flag causes the error to be
4981 ignored. This is to catch over-sized switches generated by gcc on
4982 systems which don't support the broken .word hack.
4983 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4984 write.c (fixup_segment): check for signed .word overflow if
4985 WARN_SIGNED_OVERFLOW_WORD.
4987 * write.c (fixup_segment): fixed missing parens in expression

5004 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5006 * input-scrub.c (input_scrub_push): call input_file_begin, not
5008 messages.c (as_perror): print ": " between the passed in error and
5009 the strerror, like perror does.

5014 From Steve Chamberlain:
5015 Makefile.in: Handle m68*-*-coff*.
5016 read.c, read.h: add mult argument to s_space
5018 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5019 Motorola and MIT syntax; gas can now assemble either type of
5021 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5028 (fixup_segment) set fx_subsy to 0.
5029 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5031 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5034 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5036 * Makefile.in (LIBS): Include opcode library.

5061 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5063 * config/tc-m68k.c (init_table): Now const. Always include 68851
5064 data, so that "bc" is available to 68040 cache instructions.
5065 Added "tt0", "tt1", and 68ec030 variants.
5066 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5067 (enum _register): Added TT0, TT1.
5068 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5069 line number correctly in "internal error" messages. Don't print
5070 architecture-mismatch message for operand errors.
5072 From Colin Smith (colin@wrs.com):
5073 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5074 than install_operand.

5090 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5091 so that we can assemble hand-written libgcc code.

5095 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5096 has already been formatted (but may still contain %-characters).
5099 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5101 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5102 written with indirection on the last two operands, which can be
5103 either data or address registers. Added a new operand type 'r'
5104 which accepts either register type. Added '(' to notend stuff in
5105 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5107 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

5121 (relax_align): If linkrelax, provide extra padding.
5123 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5124 their not having symbols associated.
5126 * tc-i960.c (norelax, instrument_branches): Default initializer is
5128 (linkrelax): Delete variable definition.

5152 being used with args swapped, causing occasional lossage when
5153 refilling buffers after an include file.
5155 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5157 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5158 version. Discard bogus DONTDEF version.

5161 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
5163 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5164 selected architecture, print a message saying so and listing what

5302 * write.c (write_object_file): keep the fix_tail clean, which
5303 fixes a bug in -R where relocations were being lost.
5305 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5307 * configure.in: recognize m680x0 as having sun3 emulation mode for

5354 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5356 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5357 where gcc looks for it.
5359 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5361 * Makefile.in: Changed some lines to be less confusing for some

5427 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5429 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5431 * expr.c (operand): if can't work out what sort of operand it is,
5432 then look through FLT_CHARS for a hint.
5434 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5436 * Makefile.in, configure.in: removed traces of namesubdir,
5437 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5438 copyrights to '92, changed some from Cygnus to FSF.
5440 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5441 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5442 copyrights to '92, changed some from Cygnus to FSF.
5444 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5446 * expr.c: If an expression is single comma, then return with
5447 SEG_ABSENT rather than an error - since the sparc front end does
5448 really strange things with things like fbge,a
5450 * as.h: include bfd.h if using many sections
5451 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5452 local labels didn't work.
5453 * listing.c (list_symbol_table): don't core dump when there's no
5455 * write.c, write.h: call fix_new with the right number of args on
5457 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5460 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5462 * app.c: MRI compatibility - allow single quote to start a string.
5463 * as.c: fix typo recently introduced.
5464 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5465 * expr.c: Much rewriting, to accomodate MRI syntax for
5466 expressions. Also easier to read now.
5467 * listing.c: Put back defuns
5468 * read.c: modified to accept MRI syntax, put back listing pseudo
5469 ops so that an assembler built with NO_LISTING ignores list ops
5471 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5472 machine is a SPARC or a 29K.
5473 * config/obj-aout.c: added s_sect pseudo op
5474 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5475 fill in the timestamp.
5476 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5477 anymore, define all the relocs which the tc-<x> bit will use so we
5478 can translate from them to the coff types.
5479 * config/tc-a29k.c: reloc_type isn't ane enum any more
5480 * config/tc-m68k.c: Added NO_RELOC definition.
5482 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5484 * Makefile.in: put header files before C source for TAGS; remove
5485 references to non-existent syscalls.h.
5487 * read.c, write.c subsegs.c: back out the .bss changes.
5489 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5491 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5495 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5497 * symbols.c (local_label_name): symbols now start with ^A.
5499 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5500 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5501 generate these sections. .align: will use NOP_OPCODE or 0
5502 for padding. This is just for being nice to the
5505 * expr.c (operand): changed to generate local label "\001L0"
5506 starting with a ^A so that it is recognized as a local label.
5508 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5510 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5511 i/o opcodes - inb, inw, outb and outw. string manipulation with
5512 att syntax - scmp, slod, smov, ssca, ssto.
5514 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5515 to just after .file .
5517 In obj_crawl_symbol_chain() where it tries to put the external
5518 symbols apart, with the condition:
5519 (!S_IS_DEFINED(symbolP) &&
5520 !S_IS_DEBUG(symbolP) &&
5521 !SF_GET_STATICS(symbolP))
5522 it was moving too many symbols out. So I switch it back to the
5524 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5526 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5527 so that we don't use the F_RELFLG which make the linker complain
5528 that somebody has stripped the relocation info.
5530 Also, the AIX ld program require that the relocation table
5531 is sorted by r_vaddr like the standard ATT assembler does.
5533 [he also changed the sizeof(struct ...)'s into the coff
5534 style FOOSZ macros. I'm not sure this is right, but I can't
5535 remember why. xoxorich.]
5537 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5539 * Makefile.in, configure.in, doc: use the doc. Build it, install

5544 * read.c: white space and comments only.
5546 * configure.in: use the new atof-ns32.c for ns32k.
5548 * write.c: comment change only.
5550 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5551 aren't yet integrated.
5553 * tc-i860.[hc]: blew off the dust. Something must still be done
5554 about conflicting relocation types.
5556 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5559 * tc-i960.c, tc-sparc.c: white space and comments only.
5561 * tc-a29k.h: delete duplicate macro definition.
5563 * new file atof-ns32k.c copied from hack's last unreleased gas.
5565 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5567 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5570 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5571 ChangeLog's prior to this are sketchy at best. I have logs.
5572 They just aren't ChangeLogs.
