1553 pass new argument for i, j and o cases.
1554 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

1557 rather than hard coded constants.
1558 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

1775 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1776 the table, require that the one without bit 0x1000000 set come

1890 still being worked on. Mark Elf configurations (except sparc and
1891 i386) as developmental. Deleted cases matching some generic names
1892 in favor of more specific names. (E.g., when we get Alpha

3070 * Extensive changes to permit symbols to contain any expression
3071 type and to delay the computation of the expression until the
3072 value is actually needed. This permits setting symbols to values
3073 calculated based on object code size. Expressions were changed to
3074 no longer be in a section, to stop the overloading of segment and
3075 expression type that previously occurred.
3077 * as.c (big_section, pass1_section, diff_section, absent_section):
3079 (expr_section): Added (used for dummy symbols which hold

3188 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
3189 calculating opP->isiz; this permits the expression size to be
3190 determined as well, later on.

3204 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
3206 * read.c (float_cons): Simplified parsing logic. If
3207 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.

3210 use new macro tc_frob_label.
3211 * config/tc-hppa.h (tc_frob_label): Define.

4286 to small, undefined and/or readonly sections if appropriate.
4287 Don't output symbol names containing \001 characters.
4288 (ecoff_frob_file): Make sure at least one fdr is output.

4397 avoid some redefinition complaints on some systems.
4398 (const, volatile): Don't need these conditionally defined if we
4399 use CONST and VOLATILE from ansidecl.h.
4400 (seg_name): Use CONST, not const.
4402 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4404 * config/tc-mips.c: Reindented to GNU standards.

4408 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4409 (fixup_segment): Add a29k special case; the linker is not prepared
4410 to see a segment offset here.
4412 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4415 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4417 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4437 * Makefile.in (targ-cpu.o): Depend on config.h.
4439 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4441 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4442 dropping a space immediately following an identifier.
4443 * expr.c, write.c: Rewrote assert expressions to not use multiple
4444 lines; I don't think that can be done portably.
4445 * config/tc-mips.c (macro): Use $AT if target register is zero in
4446 load instruction, which it can be for a floating point load.
4448 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4469 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4471 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4472 to be on a single line.
4474 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4476 * Makefile.in (config.h): Create file, writing out definitions of

4520 prototypes for all static functions. Moved existing minimal
4521 debugging format support info #ifndef OBJ_ECOFF blocks.

4523 does not support a non sign extended high 16 bits reloc. Adjusted
4524 all callers accordingly.
4525 (tc_get_register): Renamed from get_register, and made non-static.
4527 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4570 * make-gas.com: Find obstack.obj if it's not in the current
4572 * read.c (s_ignore): Don't declare is_end_of_line. It's
4573 redundant, and triggers a VMS gcc compiler bug.
4575 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4576 current segment as an argument. (Ignored in all cases but VMS.)
4577 All callers and definitions changed.

4706 * read.c: Don't include ctype.h.
4707 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
4708 for now; should be machine-dependent.
4710 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
4711 targets, forcing BFD use.
4713 Wed Feb 17 18:59:03 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4715 * config/tc-sparc.c: Use PARAMS macro for static function

4874 md_relax_table): Use default zero initialization.
4875 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4876 latter, instead of selecting with preprocessor conditionals.
4878 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4880 * configure.in: recognise all sparclite variants

4890 * expr.c (operand): If character other than comma or newline is a
4891 logical end-of-line character, use the newline case.
4892 From Eric Youngdale:
4893 (operand): Set X_add_number field for floating-point numbers.
4894 (operand): Treat zero byte as end-of-operand.
4896 * configure.in (per-target): Look for with_bfd_assembler option.
4897 For now, only accept "no", until the merge is done.
4899 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4900 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4906 * expr.c: Add "const" modifier to hex_value.
4907 * symbols.c: Finish conversion to S_* macros in the VMS only
4908 parts of the program. Add "const" modifier to
4909 md_[long,short]_jump_size. Remove declaration of const_flag
4910 (which will be declared in obj-vms.h).
4911 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4912 Fix arguments to VMS_write_object_file.
4913 * config-gas.com: New file. Script for VMS systems to set up the
4914 configuration to build gas for VMS, and create config.status.
4915 * make-gas.com: Redone to work with new scheme.
4916 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4918 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4919 will swap bytes if needed on a big endian system. Use throughout
4921 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4922 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4923 types of malformed stabs. Change parsing algorithm so that we are
4924 more certain of having all of the information that we need on hand.
4925 * obj-vms.c (final_forward_reference): New function, used to help
4926 resolve the data types of as many struct elements as possible
4927 when some part of the struct is not fully defined by the compiler.

4930 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4931 as symbols as well in the object file. Look for external functions
4932 that start with "__vt.", and turn them into variables, since the
4933 g++ compiler is incapable of doing this.
4934 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4936 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4937 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4938 have the name of the source file yet.
4939 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4941 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4943 * read.c (s_data): Always use "data_section", since it'll map to
4944 SEG_DATA or SEG_E1 if needed.
4945 (s_lcomm): Likewise with bss_section.
4946 (s_fill): Use memset, not bzero.
4948 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4970 (big_section, reg_section, pass1_section, diff_section,
4971 absent_section, text_section, data_section, bss_section): If
4972 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4973 mapping to segT enum values.
4974 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4975 if these are used or defined, if BFD_ASSEMBLER.
4976 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4977 subseg_new split into two functions.
4978 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4980 * as.h (volatile): Don't define if already defined.
4981 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4983 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4984 declare with format attribute for -Wformat checking.
4986 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4988 * app.c, config/tc-*.c: Don't include read.h, since it is already
4991 * These are based on patches from Minh Tran-le
4992 <mtranle@paris.intellicorp.com>.
4993 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4994 obj_format coffbfd and gas_target i386coff for target.
4995 (i[34]86-*-isc*): New host (uses sysv).
4996 * config/i386aix.mt: Removed (no longer used).
4997 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4999 (LDFLAGS): Added, defined as -shlib.
5000 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5001 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5002 (DOT_LABEL_PREFIX): Define.
5003 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5004 name rather than L0\001.
5005 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5007 * symbols.c, symbols.h (local_bss_counter): Removed.
5008 * write.c (write_object_file): bss no longer uses

5016 (size_section): Restored sanity check.
5017 (do_relocs_for): Base section address on s_paddr rather than
5018 computing it. Adjust a29k R_IHIHALF special case to account for
5019 section paddr (used to require paddr to be zero). If there are no
5020 reclos, set s_relptr to 0. Set relocation size in object_headers.
5021 (fill_section): Always set s_vaddr here, removing
5022 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5023 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5024 Set STYP_INFO for .comment.
5025 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5026 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5028 H_{SET,GET}_* macros.
5029 (do_linenos_for): Set lineno size in object_headers.
5030 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5031 set s_vaddr here. If string_byte_count remains 4, set it back to
5032 0, and only write strings out if there are some. Call
5033 fill_section before do_relocs_for and do_linenos_for.
5034 (obj_coff_section): Handle optional quoted second argument giving
5035 section characteristics.
5036 (obj_coff_bss): Added to handle .bss.
5037 (obj_coff_ident): Added to handle .ident (puts string in .comment

5057 (do_scrub_next_char): For \", return " not '.
5058 (symbol_chars): Now const.
5060 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5061 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5063 * config/obj-coff.h: Don't use #elif.
5065 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5066 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5068 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5070 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5090 SEG_BSS, fill with NOP_OPCODE.
5091 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5092 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5093 using ZERO_BASED_SEGMENTS.
5094 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5095 never set segment address for SEG_E2 (.bss) and don't write out
5096 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5097 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5098 definitions, and don't merge tags with non-tags. Check for .bf
5099 rather than just checking whether the second character is b and
5100 the third character is f.
5101 (obj_coff_val): gcc can generate values which we don't handle
5102 correctly; discard information for now, since it only affects the
5103 debugging information.

5105 (yank_symbols): Don't merge labels.
5106 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5161 options. Updated options documentation for m68k. Some minor
5162 wording/punctuation changes.
5164 Mon Nov 30 11:42:11 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5166 * configure.in: Accept target OS "vms".

5218 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
5220 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
5223 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.

5252 could be doing emulation.
5254 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5257 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5286 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5288 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5289 constant will not fit in an immediate field.
5290 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5325 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5327 * Support for i386-sysv.
5328 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5368 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5370 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5371 #elif, since it is not supported by old compilers.
5372 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5373 couple of expressions in tc-m68k.c.
5375 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5377 * read.c (cons): If NO_RELOC is defined, use it.
5379 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5381 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5383 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5384 local labels to start with a .) and set REGISTER_PREFIX to %.
5385 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5387 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5403 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5404 sections starting from zero, rather than making them consecutive.
5405 This makes subsequent reloc calculations easier, esp if the object
5406 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5407 allocate lcomm in .data rather than in .bss. It seems that some
5408 tools can't cope with a non-zero sized bss before linkage.
5410 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5412 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5431 * Makefile.in (install): if $(tooldir) exists, install as in
5434 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5436 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5437 .word is < -32768 or > 32767. The -J flag causes the error to be
5438 ignored. This is to catch over-sized switches generated by gcc on
5439 systems which don't support the broken .word hack.
5440 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5441 write.c (fixup_segment): check for signed .word overflow if
5442 WARN_SIGNED_OVERFLOW_WORD.
5444 * write.c (fixup_segment): fixed missing parens in expression
5445 checking for byte or word overflow.

5461 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5463 * input-scrub.c (input_scrub_push): call input_file_begin, not
5465 messages.c (as_perror): print ": " between the passed in error and
5466 the strerror, like perror does.

5471 From Steve Chamberlain:
5472 Makefile.in: Handle m68*-*-coff*.
5473 read.c, read.h: add mult argument to s_space
5475 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5476 Motorola and MIT syntax; gas can now assemble either type of
5478 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5484 (write_object_file) call fixup_mdeps
5485 (fixup_segment) set fx_subsy to 0.
5486 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5488 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5491 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5493 * Makefile.in (LIBS): Include opcode library.
5495 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5518 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5520 * config/tc-m68k.c (init_table): Now const. Always include 68851
5521 data, so that "bc" is available to 68040 cache instructions.
5522 Added "tt0", "tt1", and 68ec030 variants.
5523 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5524 (enum _register): Added TT0, TT1.
5525 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5526 line number correctly in "internal error" messages. Don't print
5527 architecture-mismatch message for operand errors.
5529 From Colin Smith (colin@wrs.com):
5530 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5531 than install_operand.

5547 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5548 so that we can assemble hand-written libgcc code.

5552 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5553 has already been formatted (but may still contain %-characters).
5556 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5558 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5559 written with indirection on the last two operands, which can be
5560 either data or address registers. Added a new operand type 'r'
5561 which accepts either register type. Added '(' to notend stuff in
5562 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5564 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

5580 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5581 their not having symbols associated.
5583 * tc-i960.c (norelax, instrument_branches): Default initializer is
5585 (linkrelax): Delete variable definition.

5609 being used with args swapped, causing occasional lossage when
5610 refilling buffers after an include file.
5612 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5614 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5615 version. Discard bogus DONTDEF version.

5620 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5621 selected architecture, print a message saying so and listing what

5759 * write.c (write_object_file): keep the fix_tail clean, which
5760 fixes a bug in -R where relocations were being lost.
5762 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5764 * configure.in: recognize m680x0 as having sun3 emulation mode for

5811 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5813 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5814 where gcc looks for it.
5816 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5818 * Makefile.in: Changed some lines to be less confusing for some

5884 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5886 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5888 * expr.c (operand): if can't work out what sort of operand it is,
5889 then look through FLT_CHARS for a hint.
5891 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5893 * Makefile.in, configure.in: removed traces of namesubdir,

5895 copyrights to '92, changed some from Cygnus to FSF.
5897 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5898 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5899 copyrights to '92, changed some from Cygnus to FSF.
5901 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5903 * expr.c: If an expression is single comma, then return with
5904 SEG_ABSENT rather than an error - since the sparc front end does
5905 really strange things with things like fbge,a
5907 * as.h: include bfd.h if using many sections
5908 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5909 local labels didn't work.
5910 * listing.c (list_symbol_table): don't core dump when there's no
5912 * write.c, write.h: call fix_new with the right number of args on
5914 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5917 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5919 * app.c: MRI compatibility - allow single quote to start a string.
5920 * as.c: fix typo recently introduced.
5921 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5922 * expr.c: Much rewriting, to accomodate MRI syntax for
5923 expressions. Also easier to read now.
5924 * listing.c: Put back defuns
5925 * read.c: modified to accept MRI syntax, put back listing pseudo
5926 ops so that an assembler built with NO_LISTING ignores list ops
5928 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5929 machine is a SPARC or a 29K.
5930 * config/obj-aout.c: added s_sect pseudo op
5931 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5932 fill in the timestamp.
5933 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5934 anymore, define all the relocs which the tc-<x> bit will use so we
5935 can translate from them to the coff types.
5936 * config/tc-a29k.c: reloc_type isn't ane enum any more
5937 * config/tc-m68k.c: Added NO_RELOC definition.
5939 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5941 * Makefile.in: put header files before C source for TAGS; remove
5942 references to non-existent syscalls.h.
5944 * read.c, write.c subsegs.c: back out the .bss changes.
5946 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5948 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5952 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5954 * symbols.c (local_label_name): symbols now start with ^A.
5956 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5957 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5958 generate these sections. .align: will use NOP_OPCODE or 0
5959 for padding. This is just for being nice to the
5962 * expr.c (operand): changed to generate local label "\001L0"
5963 starting with a ^A so that it is recognized as a local label.
5965 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5967 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5968 i/o opcodes - inb, inw, outb and outw. string manipulation with
5969 att syntax - scmp, slod, smov, ssca, ssto.
5971 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5972 to just after .file .
5974 In obj_crawl_symbol_chain() where it tries to put the external
5975 symbols apart, with the condition:
5976 (!S_IS_DEFINED(symbolP) &&
5977 !S_IS_DEBUG(symbolP) &&
5978 !SF_GET_STATICS(symbolP))
5979 it was moving too many symbols out. So I switch it back to the
5981 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5983 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5984 so that we don't use the F_RELFLG which make the linker complain
5985 that somebody has stripped the relocation info.
5987 Also, the AIX ld program require that the relocation table
5988 is sorted by r_vaddr like the standard ATT assembler does.
5990 [he also changed the sizeof(struct ...)'s into the coff
5991 style FOOSZ macros. I'm not sure this is right, but I can't
5992 remember why. xoxorich.]
5994 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5996 * Makefile.in, configure.in, doc: use the doc. Build it, install

6001 * read.c: white space and comments only.
6003 * configure.in: use the new atof-ns32.c for ns32k.
6005 * write.c: comment change only.
6007 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6008 aren't yet integrated.
6010 * tc-i860.[hc]: blew off the dust. Something must still be done
6011 about conflicting relocation types.
6013 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6016 * tc-i960.c, tc-sparc.c: white space and comments only.
6018 * tc-a29k.h: delete duplicate macro definition.
6020 * new file atof-ns32k.c copied from hack's last unreleased gas.
6022 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6024 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6027 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6028 ChangeLog's prior to this are sketchy at best. I have logs.
6029 They just aren't ChangeLogs.
