2014 default is to assume production environment, and reject configs
2015 still being worked on. Mark Elf configurations (except sparc and
2016 i386) as developmental. Deleted cases matching some generic names
2017 in favor of more specific names. (E.g., when we get Alpha

2044 are only used within tc-hppa.c static. PARAMize all functions.
2045 Add comments to functions. Delete unused functions, variables,
2046 #defines, etc. Delete unused members within structures. Delete
2047 ldil;ble hacks -- it is believed they were installed to work
2048 around old gas bugs. Avoid using mixed case for local
2049 functions, variables, and structures. Fix formatting problems
2050 not found by GNU-indent. Add FIXME notices for things which
2051 should be worked on the near future. Delete lots of old

2130 BFD_RELOC_NONE to silence compiler warnings.
2131 (md_assemble): Keep track of the instruction size. Allow white
2132 space between the $ and the constant for compatibility with older

4316 Thu Apr 8 15:51:28 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4318 * doc/Makefile.in: as.texinfo is in $(srcdir). Use

4470 dependencies are read, not when they are used).
4472 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4473 a29k .bss section; the mondfe program doesn't like it.

4494 source directory, if that's not the current directory.
4496 * configure.in (per-host): Accept MIPS host with BSD version

4522 avoid some redefinition complaints on some systems.
4523 (const, volatile): Don't need these conditionally defined if we
4524 use CONST and VOLATILE from ansidecl.h.
4525 (seg_name): Use CONST, not const.
4527 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4529 * config/tc-mips.c: Reindented to GNU standards.
4531 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
4533 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4534 (fixup_segment): Add a29k special case; the linker is not prepared
4535 to see a segment offset here.
4537 * app.c (do_scrub_next_char): Added new state, 10, modifying state
4538 9 to only keep a space in between identifier characters.
4540 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4542 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4543 srcdir, might be in objdir.

4562 * Makefile.in (targ-cpu.o): Depend on config.h.
4564 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4566 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4567 dropping a space immediately following an identifier.
4568 * expr.c, write.c: Rewrote assert expressions to not use multiple
4569 lines; I don't think that can be done portably.
4570 * config/tc-mips.c (macro): Use $AT if target register is zero in
4571 load instruction, which it can be for a floating point load.
4573 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4594 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4596 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4597 to be on a single line.

4644 * config/tc-mips.c: Rearranged for ECOFF support. Added
4645 prototypes for all static functions. Moved existing minimal
4646 debugging format support info #ifndef OBJ_ECOFF blocks.

4695 * make-gas.com: Find obstack.obj if it's not in the current
4697 * read.c (s_ignore): Don't declare is_end_of_line. It's
4698 redundant, and triggers a VMS gcc compiler bug.
4700 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4701 current segment as an argument. (Ignored in all cases but VMS.)

4999 md_relax_table): Use default zero initialization.
5000 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

5015 * expr.c (operand): If character other than comma or newline is a
5016 logical end-of-line character, use the newline case.
5017 From Eric Youngdale:
5018 (operand): Set X_add_number field for floating-point numbers.
5019 (operand): Treat zero byte as end-of-operand.
5021 * configure.in (per-target): Look for with_bfd_assembler option.
5022 For now, only accept "no", until the merge is done.
5024 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5025 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5031 * expr.c: Add "const" modifier to hex_value.
5032 * symbols.c: Finish conversion to S_* macros in the VMS only
5033 parts of the program. Add "const" modifier to
5034 md_[long,short]_jump_size. Remove declaration of const_flag
5035 (which will be declared in obj-vms.h).
5036 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5037 Fix arguments to VMS_write_object_file.
5038 * config-gas.com: New file. Script for VMS systems to set up the
5039 configuration to build gas for VMS, and create config.status.
5040 * make-gas.com: Redone to work with new scheme.
5041 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

5046 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5047 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5048 types of malformed stabs. Change parsing algorithm so that we are
5049 more certain of having all of the information that we need on hand.
5050 * obj-vms.c (final_forward_reference): New function, used to help
5051 resolve the data types of as many struct elements as possible
5052 when some part of the struct is not fully defined by the compiler.

5055 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5056 as symbols as well in the object file. Look for external functions

5069 SEG_DATA or SEG_E1 if needed.
5070 (s_lcomm): Likewise with bss_section.
5071 (s_fill): Use memset, not bzero.
5073 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5096 absent_section, text_section, data_section, bss_section): If
5097 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5098 mapping to segT enum values.
5099 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5100 if these are used or defined, if BFD_ASSEMBLER.
5101 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5102 subseg_new split into two functions.
5103 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5105 * as.h (volatile): Don't define if already defined.
5106 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5108 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5109 declare with format attribute for -Wformat checking.
5111 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5113 * app.c, config/tc-*.c: Don't include read.h, since it is already
5116 * These are based on patches from Minh Tran-le
5117 <mtranle@paris.intellicorp.com>.
5118 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5119 obj_format coffbfd and gas_target i386coff for target.

5121 * config/i386aix.mt: Removed (no longer used).
5122 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5124 (LDFLAGS): Added, defined as -shlib.
5125 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5126 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5127 (DOT_LABEL_PREFIX): Define.
5128 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5129 name rather than L0\001.
5130 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5132 * symbols.c, symbols.h (local_bss_counter): Removed.
5133 * write.c (write_object_file): bss no longer uses
5134 local_bss_counter. Pass correct data and bss size to
5135 VMS_write_object_file.
5136 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
5137 argument, rather than using local_bss_counter.

5141 (size_section): Restored sanity check.
5142 (do_relocs_for): Base section address on s_paddr rather than
5143 computing it. Adjust a29k R_IHIHALF special case to account for
5144 section paddr (used to require paddr to be zero). If there are no
5145 reclos, set s_relptr to 0. Set relocation size in object_headers.
5146 (fill_section): Always set s_vaddr here, removing
5147 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5148 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5149 Set STYP_INFO for .comment.
5150 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5151 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
5152 (crawl_symbols): Handle 8 character section name correctly. Use
5153 H_{SET,GET}_* macros.
5154 (do_linenos_for): Set lineno size in object_headers.
5155 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5156 set s_vaddr here. If string_byte_count remains 4, set it back to
5157 0, and only write strings out if there are some. Call
5158 fill_section before do_relocs_for and do_linenos_for.
5159 (obj_coff_section): Handle optional quoted second argument giving
5160 section characteristics.

5188 * config/obj-coff.h: Don't use #elif.
5190 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

5230 (yank_symbols): Don't merge labels.
5231 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5377 could be doing emulation.
5379 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5382 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5452 * Support for i386-sysv.
5453 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5493 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5495 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5496 #elif, since it is not supported by old compilers.
5497 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5498 couple of expressions in tc-m68k.c.
5500 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

5526 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5528 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5529 sections starting from zero, rather than making them consecutive.
5530 This makes subsequent reloc calculations easier, esp if the object
5531 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5532 allocate lcomm in .data rather than in .bss. It seems that some
5533 tools can't cope with a non-zero sized bss before linkage.

5559 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5561 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5562 .word is < -32768 or > 32767. The -J flag causes the error to be
5563 ignored. This is to catch over-sized switches generated by gcc on
5564 systems which don't support the broken .word hack.
5565 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5566 write.c (fixup_segment): check for signed .word overflow if
5567 WARN_SIGNED_OVERFLOW_WORD.

5586 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5588 * input-scrub.c (input_scrub_push): call input_file_begin, not
5590 messages.c (as_perror): print ": " between the passed in error and
5591 the strerror, like perror does.
5593 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

5610 (fixup_segment) set fx_subsy to 0.
5611 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5613 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5616 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5618 * Makefile.in (LIBS): Include opcode library.

5640 tc-i960.c (md_ri_to_chars): Always output bout object file in
5641 little endian byte order (used to use endianness of host).
5643 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5645 * config/tc-m68k.c (init_table): Now const. Always include 68851
5646 data, so that "bc" is available to 68040 cache instructions.
5647 Added "tt0", "tt1", and 68ec030 variants.
5648 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5649 (enum _register): Added TT0, TT1.
5650 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5651 line number correctly in "internal error" messages. Don't print
5652 architecture-mismatch message for operand errors.
5654 From Colin Smith (colin@wrs.com):
5655 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5656 than install_operand.
5658 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5660 * listing.c (buffer_line): rewind to the start of include
5661 files, they might be included twice.

5665 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
5667 * Makefile.in: defined TARGET_CPU for C code so that it can choose
5668 one element of a family.
5670 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5672 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5673 so that we can assemble hand-written libgcc code.
5675 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5677 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5678 has already been formatted (but may still contain %-characters).
5681 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5683 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5684 written with indirection on the last two operands, which can be
5685 either data or address registers. Added a new operand type 'r'
5686 which accepts either register type. Added '(' to notend stuff in
5687 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5689 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

5706 their not having symbols associated.
5708 * tc-i960.c (norelax, instrument_branches): Default initializer is
5710 (linkrelax): Delete variable definition.

5734 being used with args swapped, causing occasional lossage when
5735 refilling buffers after an include file.
5737 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5739 * messages.c (as_tsktsk): Use correct ANSI form for stdarg

5797 processor/opcode mismatch, so reword the error message.
5798 (md_assemble): If no CPU has been set (even if FPU/PMMU
5799 characteristics have been), default to 68020. Don't need extra
5800 quotes around error string.

5804 * read.c (potable): Revert sac's incorrect change made Jul 13.

5882 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5884 * write.c (write_object_file): keep the fix_tail clean, which
5885 fixes a bug in -R where relocations were being lost.
5887 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5889 * configure.in: recognize m680x0 as having sun3 emulation mode for

5933 * write.c (write_object_file): For b.out format, round up section
5934 start addresses to match required alignment.
5936 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5938 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5939 where gcc looks for it.
5941 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5943 * Makefile.in: Changed some lines to be less confusing for some

6009 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6011 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6013 * expr.c (operand): if can't work out what sort of operand it is,
6014 then look through FLT_CHARS for a hint.
6016 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6018 * Makefile.in, configure.in: removed traces of namesubdir,

6020 copyrights to '92, changed some from Cygnus to FSF.
6022 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6023 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6024 copyrights to '92, changed some from Cygnus to FSF.
6026 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6028 * expr.c: If an expression is single comma, then return with
6029 SEG_ABSENT rather than an error - since the sparc front end does
6030 really strange things with things like fbge,a
6032 * as.h: include bfd.h if using many sections
6033 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6034 local labels didn't work.
6035 * listing.c (list_symbol_table): don't core dump when there's no
6037 * write.c, write.h: call fix_new with the right number of args on
6039 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6042 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6044 * app.c: MRI compatibility - allow single quote to start a string.
6045 * as.c: fix typo recently introduced.
6046 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6047 * expr.c: Much rewriting, to accomodate MRI syntax for
6048 expressions. Also easier to read now.
6049 * listing.c: Put back defuns
6050 * read.c: modified to accept MRI syntax, put back listing pseudo
6051 ops so that an assembler built with NO_LISTING ignores list ops
6053 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6054 machine is a SPARC or a 29K.
6055 * config/obj-aout.c: added s_sect pseudo op
6056 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6057 fill in the timestamp.
6058 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6059 anymore, define all the relocs which the tc-<x> bit will use so we
6060 can translate from them to the coff types.
6061 * config/tc-a29k.c: reloc_type isn't ane enum any more
6062 * config/tc-m68k.c: Added NO_RELOC definition.
6064 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6066 * Makefile.in: put header files before C source for TAGS; remove
6067 references to non-existent syscalls.h.
6069 * read.c, write.c subsegs.c: back out the .bss changes.
6071 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6073 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6077 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6079 * symbols.c (local_label_name): symbols now start with ^A.
6081 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6082 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6083 generate these sections. .align: will use NOP_OPCODE or 0
6084 for padding. This is just for being nice to the
6087 * expr.c (operand): changed to generate local label "\001L0"
6088 starting with a ^A so that it is recognized as a local label.
6090 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6092 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6093 i/o opcodes - inb, inw, outb and outw. string manipulation with
6094 att syntax - scmp, slod, smov, ssca, ssto.
6096 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6097 to just after .file .
6099 In obj_crawl_symbol_chain() where it tries to put the external
6100 symbols apart, with the condition:
6101 (!S_IS_DEFINED(symbolP) &&
6102 !S_IS_DEBUG(symbolP) &&
6103 !SF_GET_STATICS(symbolP))
6104 it was moving too many symbols out. So I switch it back to the
6106 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6108 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6109 so that we don't use the F_RELFLG which make the linker complain
6110 that somebody has stripped the relocation info.
6112 Also, the AIX ld program require that the relocation table
6113 is sorted by r_vaddr like the standard ATT assembler does.
6115 [he also changed the sizeof(struct ...)'s into the coff
6116 style FOOSZ macros. I'm not sure this is right, but I can't
6117 remember why. xoxorich.]
6119 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6121 * Makefile.in, configure.in, doc: use the doc. Build it, install

6126 * read.c: white space and comments only.
6128 * configure.in: use the new atof-ns32.c for ns32k.
6130 * write.c: comment change only.
6132 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6133 aren't yet integrated.
6135 * tc-i860.[hc]: blew off the dust. Something must still be done
6136 about conflicting relocation types.
6138 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6141 * tc-i960.c, tc-sparc.c: white space and comments only.
6143 * tc-a29k.h: delete duplicate macro definition.
6145 * new file atof-ns32k.c copied from hack's last unreleased gas.
6147 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6149 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6152 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6153 ChangeLog's prior to this are sketchy at best. I have logs.
6154 They just aren't ChangeLogs.
