1949 OPTIONAL_REGISTER_PREFIX if either is already defined.
1951 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
1953 * configure.in: Set bfd_gas for all sparc targets. Added facility
1954 for keeping or rejecting configurations still under development;
1955 default is to assume production environment, and reject configs
1956 still being worked on. Mark Elf configurations (except sparc and
1957 i386) as developmental. Deleted cases matching some generic names
1958 in favor of more specific names. (E.g., when we get Alpha
1959 support, we'll still only support VMS for Vax.)

1974 against contaminating all of GAS with the internals of tc-hppa.c
1975 through inclusion of tc-hppa.h. Delete all forward declarations
1976 for functions only used within tc-hppa.c, likewise for structures,
1977 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1978 conditional code in a few small places.
1980 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1981 structures, global variables, forward declarations together.
1982 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
1983 conditional code -- try to group conditional code together
1984 into a few places. Make all functions and variables which
1985 are only used within tc-hppa.c static. PARAMize all functions.
1986 Add comments to functions. Delete unused functions, variables,
1987 #defines, etc. Delete unused members within structures. Delete
1988 ldil;ble hacks -- it is believed they were installed to work
1989 around old gas bugs. Avoid using mixed case for local
1990 functions, variables, and structures. Fix formatting problems
1991 not found by GNU-indent. Add FIXME notices for things which
1992 should be worked on the near future. Delete lots of old
1993 useless (1.36 PA-SOM) code.

2010 * config/tc-hppa.c: Likewise.
2012 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2013 of elf32_symbol_type.
2014 (pa_export_args): Likewise.
2015 (elf_hppa_final_processing): Likewise.
2016 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

2022 a multiple of the section alignment rather than always a
2025 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2066 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2068 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2069 ELF, since the ELF object format does not have these type of
2070 relocations. Change the abort into as as_bad and return
2071 BFD_RELOC_NONE to silence compiler warnings.
2072 (md_assemble): Keep track of the instruction size. Allow white
2073 space between the $ and the constant for compatibility with older
2074 gases and other assemblers.

4414 a29k .bss section; the mondfe program doesn't like it.

4435 source directory, if that's not the current directory.
4437 * configure.in (per-host): Accept MIPS host with BSD version

4463 avoid some redefinition complaints on some systems.
4464 (const, volatile): Don't need these conditionally defined if we
4465 use CONST and VOLATILE from ansidecl.h.
4466 (seg_name): Use CONST, not const.
4468 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4470 * config/tc-mips.c: Reindented to GNU standards.

4474 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4475 (fixup_segment): Add a29k special case; the linker is not prepared
4476 to see a segment offset here.
4478 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4481 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4483 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4484 srcdir, might be in objdir.

4503 * Makefile.in (targ-cpu.o): Depend on config.h.
4505 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4507 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4508 dropping a space immediately following an identifier.
4509 * expr.c, write.c: Rewrote assert expressions to not use multiple
4510 lines; I don't think that can be done portably.
4511 * config/tc-mips.c (macro): Use $AT if target register is zero in
4512 load instruction, which it can be for a floating point load.
4514 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4535 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4537 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4538 to be on a single line.
4540 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4586 prototypes for all static functions. Moved existing minimal
4587 debugging format support info #ifndef OBJ_ECOFF blocks.

4636 * make-gas.com: Find obstack.obj if it's not in the current
4638 * read.c (s_ignore): Don't declare is_end_of_line. It's
4639 redundant, and triggers a VMS gcc compiler bug.
4641 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4642 current segment as an argument. (Ignored in all cases but VMS.)
4643 All callers and definitions changed.

4940 md_relax_table): Use default zero initialization.
4941 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4942 latter, instead of selecting with preprocessor conditionals.
4944 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4946 * configure.in: recognise all sparclite variants

4956 * expr.c (operand): If character other than comma or newline is a
4957 logical end-of-line character, use the newline case.
4958 From Eric Youngdale:
4959 (operand): Set X_add_number field for floating-point numbers.
4960 (operand): Treat zero byte as end-of-operand.
4962 * configure.in (per-target): Look for with_bfd_assembler option.
4963 For now, only accept "no", until the merge is done.
4965 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4966 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4972 * expr.c: Add "const" modifier to hex_value.
4973 * symbols.c: Finish conversion to S_* macros in the VMS only
4974 parts of the program. Add "const" modifier to
4975 md_[long,short]_jump_size. Remove declaration of const_flag
4976 (which will be declared in obj-vms.h).
4977 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4978 Fix arguments to VMS_write_object_file.
4979 * config-gas.com: New file. Script for VMS systems to set up the
4980 configuration to build gas for VMS, and create config.status.

4987 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4988 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4989 types of malformed stabs. Change parsing algorithm so that we are
4990 more certain of having all of the information that we need on hand.
4991 * obj-vms.c (final_forward_reference): New function, used to help
4992 resolve the data types of as many struct elements as possible
4993 when some part of the struct is not fully defined by the compiler.

4996 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4997 as symbols as well in the object file. Look for external functions

5000 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5002 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5003 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5004 have the name of the source file yet.
5005 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5007 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5009 * read.c (s_data): Always use "data_section", since it'll map to
5010 SEG_DATA or SEG_E1 if needed.
5011 (s_lcomm): Likewise with bss_section.
5012 (s_fill): Use memset, not bzero.
5014 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5039 mapping to segT enum values.
5040 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5041 if these are used or defined, if BFD_ASSEMBLER.
5042 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5043 subseg_new split into two functions.
5044 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5046 * as.h (volatile): Don't define if already defined.
5047 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5049 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5050 declare with format attribute for -Wformat checking.
5052 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5054 * app.c, config/tc-*.c: Don't include read.h, since it is already
5057 * These are based on patches from Minh Tran-le
5058 <mtranle@paris.intellicorp.com>.
5059 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5060 obj_format coffbfd and gas_target i386coff for target.
5061 (i[34]86-*-isc*): New host (uses sysv).
5062 * config/i386aix.mt: Removed (no longer used).
5063 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5065 (LDFLAGS): Added, defined as -shlib.
5066 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5067 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5068 (DOT_LABEL_PREFIX): Define.
5069 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5070 name rather than L0\001.
5071 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5073 * symbols.c, symbols.h (local_bss_counter): Removed.

5082 (size_section): Restored sanity check.
5083 (do_relocs_for): Base section address on s_paddr rather than
5084 computing it. Adjust a29k R_IHIHALF special case to account for
5085 section paddr (used to require paddr to be zero). If there are no
5086 reclos, set s_relptr to 0. Set relocation size in object_headers.
5087 (fill_section): Always set s_vaddr here, removing
5088 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5089 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5090 Set STYP_INFO for .comment.
5091 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5092 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5094 H_{SET,GET}_* macros.
5095 (do_linenos_for): Set lineno size in object_headers.
5096 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5097 set s_vaddr here. If string_byte_count remains 4, set it back to
5098 0, and only write strings out if there are some. Call
5099 fill_section before do_relocs_for and do_linenos_for.
5100 (obj_coff_section): Handle optional quoted second argument giving
5101 section characteristics.
5102 (obj_coff_bss): Added to handle .bss.
5103 (obj_coff_ident): Added to handle .ident (puts string in .comment

5123 (do_scrub_next_char): For \", return " not '.
5124 (symbol_chars): Now const.
5126 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5127 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5129 * config/obj-coff.h: Don't use #elif.
5131 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5132 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5134 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5136 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5158 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5159 using ZERO_BASED_SEGMENTS.
5160 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5161 never set segment address for SEG_E2 (.bss) and don't write out
5162 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5163 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5164 definitions, and don't merge tags with non-tags. Check for .bf
5165 rather than just checking whether the second character is b and
5166 the third character is f.

5318 could be doing emulation.
5320 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5323 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5352 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5354 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5355 constant will not fit in an immediate field.
5356 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5391 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5393 * Support for i386-sysv.
5394 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5432 * tc-z8k.c: lots of bug fixes
5434 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5436 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5437 #elif, since it is not supported by old compilers.
5438 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5439 couple of expressions in tc-m68k.c.
5441 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5443 * read.c (cons): If NO_RELOC is defined, use it.
5445 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5447 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5449 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5450 local labels to start with a .) and set REGISTER_PREFIX to %.
5451 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5453 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5467 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5469 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5470 sections starting from zero, rather than making them consecutive.
5471 This makes subsequent reloc calculations easier, esp if the object
5472 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5473 allocate lcomm in .data rather than in .bss. It seems that some
5474 tools can't cope with a non-zero sized bss before linkage.
5476 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5478 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5482 "-mno-688[58]1" options.
5484 * tc-m68k.c: Added CPU32 support.

5493 Change LIBDEPS dependence to LIBS.
5495 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
5497 * Makefile.in (install): if $(tooldir) exists, install as in
5500 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5502 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5503 .word is < -32768 or > 32767. The -J flag causes the error to be
5504 ignored. This is to catch over-sized switches generated by gcc on
5505 systems which don't support the broken .word hack.
5506 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5507 write.c (fixup_segment): check for signed .word overflow if
5508 WARN_SIGNED_OVERFLOW_WORD.
5510 * write.c (fixup_segment): fixed missing parens in expression
5511 checking for byte or word overflow.
5513 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

5527 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5529 * input-scrub.c (input_scrub_push): call input_file_begin, not
5531 messages.c (as_perror): print ": " between the passed in error and
5532 the strerror, like perror does.
5534 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

5537 From Steve Chamberlain:
5538 Makefile.in: Handle m68*-*-coff*.
5539 read.c, read.h: add mult argument to s_space
5541 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5542 Motorola and MIT syntax; gas can now assemble either type of
5544 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5550 (write_object_file) call fixup_mdeps
5551 (fixup_segment) set fx_subsy to 0.
5552 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5554 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5557 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5559 * Makefile.in (LIBS): Include opcode library.
5561 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5581 tc-i960.c (md_ri_to_chars): Always output bout object file in
5582 little endian byte order (used to use endianness of host).
5584 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5586 * config/tc-m68k.c (init_table): Now const. Always include 68851
5587 data, so that "bc" is available to 68040 cache instructions.
5588 Added "tt0", "tt1", and 68ec030 variants.
5589 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5590 (enum _register): Added TT0, TT1.
5591 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5592 line number correctly in "internal error" messages. Don't print
5593 architecture-mismatch message for operand errors.
5595 From Colin Smith (colin@wrs.com):
5596 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5597 than install_operand.

5601 * listing.c (buffer_line): rewind to the start of include
5602 files, they might be included twice.
5604 * z8k.c, z8k.h, z8k.mt: z8000 support stuff

5609 one element of a family.
5611 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5613 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5614 so that we can assemble hand-written libgcc code.
5616 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5618 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5619 has already been formatted (but may still contain %-characters).
5622 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5624 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5625 written with indirection on the last two operands, which can be
5626 either data or address registers. Added a new operand type 'r'
5627 which accepts either register type. Added '(' to notend stuff in
5628 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5630 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

5641 data_last_frag): No longer static.
5642 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
5643 defined, call it. Change segments before calling fixup_segment.
5644 (relax_align): If linkrelax, provide extra padding.
5646 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5647 their not having symbols associated.
5649 * tc-i960.c (norelax, instrument_branches): Default initializer is
5651 (linkrelax): Delete variable definition.

5738 processor/opcode mismatch, so reword the error message.
5739 (md_assemble): If no CPU has been set (even if FPU/PMMU
5740 characteristics have been), default to 68020. Don't need extra
5741 quotes around error string.

5823 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5825 * write.c (write_object_file): keep the fix_tail clean, which
5826 fixes a bug in -R where relocations were being lost.
5828 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5830 * configure.in: recognize m680x0 as having sun3 emulation mode for

5875 start addresses to match required alignment.
5877 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5879 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5880 where gcc looks for it.
5882 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5884 * Makefile.in: Changed some lines to be less confusing for some

5950 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5952 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5954 * expr.c (operand): if can't work out what sort of operand it is,
5955 then look through FLT_CHARS for a hint.
5957 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5959 * Makefile.in, configure.in: removed traces of namesubdir,
5960 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5961 copyrights to '92, changed some from Cygnus to FSF.
5963 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5964 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5965 copyrights to '92, changed some from Cygnus to FSF.
5967 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5969 * expr.c: If an expression is single comma, then return with
5970 SEG_ABSENT rather than an error - since the sparc front end does
5971 really strange things with things like fbge,a
5973 * as.h: include bfd.h if using many sections
5974 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5975 local labels didn't work.
5976 * listing.c (list_symbol_table): don't core dump when there's no
5978 * write.c, write.h: call fix_new with the right number of args on
5980 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5983 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5985 * app.c: MRI compatibility - allow single quote to start a string.
5986 * as.c: fix typo recently introduced.
5987 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5988 * expr.c: Much rewriting, to accomodate MRI syntax for
5989 expressions. Also easier to read now.
5990 * listing.c: Put back defuns
5991 * read.c: modified to accept MRI syntax, put back listing pseudo
5992 ops so that an assembler built with NO_LISTING ignores list ops
5994 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5995 machine is a SPARC or a 29K.
5996 * config/obj-aout.c: added s_sect pseudo op
5997 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5998 fill in the timestamp.
5999 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6000 anymore, define all the relocs which the tc-<x> bit will use so we
6001 can translate from them to the coff types.
6002 * config/tc-a29k.c: reloc_type isn't ane enum any more
6003 * config/tc-m68k.c: Added NO_RELOC definition.
6005 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6007 * Makefile.in: put header files before C source for TAGS; remove
6008 references to non-existent syscalls.h.
6010 * read.c, write.c subsegs.c: back out the .bss changes.
6012 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6014 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6018 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6020 * symbols.c (local_label_name): symbols now start with ^A.
6022 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6023 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6024 generate these sections. .align: will use NOP_OPCODE or 0
6025 for padding. This is just for being nice to the
6028 * expr.c (operand): changed to generate local label "\001L0"
6029 starting with a ^A so that it is recognized as a local label.
6031 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6033 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6034 i/o opcodes - inb, inw, outb and outw. string manipulation with
6035 att syntax - scmp, slod, smov, ssca, ssto.
6037 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6038 to just after .file .
6040 In obj_crawl_symbol_chain() where it tries to put the external
6041 symbols apart, with the condition:
6042 (!S_IS_DEFINED(symbolP) &&
6043 !S_IS_DEBUG(symbolP) &&
6044 !SF_GET_STATICS(symbolP))
6045 it was moving too many symbols out. So I switch it back to the
6047 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6049 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6050 so that we don't use the F_RELFLG which make the linker complain
6051 that somebody has stripped the relocation info.
6053 Also, the AIX ld program require that the relocation table
6054 is sorted by r_vaddr like the standard ATT assembler does.
6056 [he also changed the sizeof(struct ...)'s into the coff
6057 style FOOSZ macros. I'm not sure this is right, but I can't
6058 remember why. xoxorich.]
6060 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6062 * Makefile.in, configure.in, doc: use the doc. Build it, install

6067 * read.c: white space and comments only.
6069 * configure.in: use the new atof-ns32.c for ns32k.
6071 * write.c: comment change only.
6073 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6074 aren't yet integrated.
6076 * tc-i860.[hc]: blew off the dust. Something must still be done
6077 about conflicting relocation types.
6079 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6082 * tc-i960.c, tc-sparc.c: white space and comments only.
6084 * tc-a29k.h: delete duplicate macro definition.
6086 * new file atof-ns32k.c copied from hack's last unreleased gas.
6088 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6090 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6093 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6094 ChangeLog's prior to this are sketchy at best. I have logs.
6095 They just aren't ChangeLogs.
