993 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
994 the table, require that the one without bit 0x1000000 set come
995 first. Require further that it be case 'b' or 'P'. The a29k

1106 for keeping or rejecting configurations still under development;
1107 default is to assume production environment, and reject configs
1108 still being worked on. Mark Elf configurations (except sparc and
1109 i386) as developmental. Deleted cases matching some generic names
1110 in favor of more specific names. (E.g., when we get Alpha

1127 through inclusion of tc-hppa.h. Delete all forward declarations
1128 for functions only used within tc-hppa.c, likewise for structures,
1129 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1130 conditional code in a few small places.
1132 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1133 structures, global variables, forward declarations together.

1135 conditional code -- try to group conditional code together
1136 into a few places. Make all functions and variables which
1137 are only used within tc-hppa.c static. PARAMize all functions.
1138 Add comments to functions. Delete unused functions, variables,
1139 #defines, etc. Delete unused members within structures. Delete
1140 ldil;ble hacks -- it is believed they were installed to work
1141 around old gas bugs. Avoid using mixed case for local
1142 functions, variables, and structures. Fix formatting problems
1143 not found by GNU-indent. Add FIXME notices for things which
1144 should be worked on the near future. Delete lots of old
1145 useless (1.36 PA-SOM) code.

1162 * config/tc-hppa.c: Likewise.
1164 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1165 of elf32_symbol_type.
1166 (pa_export_args): Likewise.
1167 (elf_hppa_final_processing): Likewise.

1173 * config/tc-hppa.c: (md_section_align): Align all sections to
1174 a multiple of the section alignment rather than always a
1177 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

1218 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1220 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1221 ELF, since the ELF object format does not have these type of
1222 relocations. Change the abort into as as_bad and return
1223 BFD_RELOC_NONE to silence compiler warnings.
1224 (md_assemble): Keep track of the instruction size. Allow white
1225 space between the $ and the constant for compatibility with older
1226 gases and other assemblers.
1227 (i386_operand): Skip spaces between $ and expression.

3790 * read.c (s_ignore): Don't declare is_end_of_line. It's
3791 redundant, and triggers a VMS gcc compiler bug.

4112 (operand): Treat zero byte as end-of-operand.
4114 * configure.in (per-target): Look for with_bfd_assembler option.
4115 For now, only accept "no", until the merge is done.
4117 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4118 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4128 (which will be declared in obj-vms.h).
4129 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4130 Fix arguments to VMS_write_object_file.
4131 * config-gas.com: New file. Script for VMS systems to set up the

4191 mapping to segT enum values.
4192 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4193 if these are used or defined, if BFD_ASSEMBLER.
4194 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4195 subseg_new split into two functions.
4196 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4198 * as.h (volatile): Don't define if already defined.
4199 (had_errors, had_warnings): Provide prototypes for ANSI C even if

4234 (size_section): Restored sanity check.
4235 (do_relocs_for): Base section address on s_paddr rather than
4236 computing it. Adjust a29k R_IHIHALF special case to account for
4237 section paddr (used to require paddr to be zero). If there are no
4238 reclos, set s_relptr to 0. Set relocation size in object_headers.
4239 (fill_section): Always set s_vaddr here, removing
4240 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4241 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4242 Set STYP_INFO for .comment.
4243 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4244 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
4245 (crawl_symbols): Handle 8 character section name correctly. Use
4246 H_{SET,GET}_* macros.
4247 (do_linenos_for): Set lineno size in object_headers.
4248 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4249 set s_vaddr here. If string_byte_count remains 4, set it back to
4250 0, and only write strings out if there are some. Call
4251 fill_section before do_relocs_for and do_linenos_for.
4252 (obj_coff_section): Handle optional quoted second argument giving
4253 section characteristics.
4254 (obj_coff_bss): Added to handle .bss.
4255 (obj_coff_ident): Added to handle .ident (puts string in .comment
4257 (obj_coff_lcomm): Put common symbols in .bss, not .data.
4258 (fixup_mdeps): Change to segment. Call frag_wane after
4260 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4261 adjustment (already happened only for common symbols, but this is
4263 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

4274 * app.c (app_push): Use memcpy, not bcopy.
4275 (do_scrub_next_char): For \", return " not '.
4276 (symbol_chars): Now const.
4278 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4279 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4281 * config/obj-coff.h: Don't use #elif.
4283 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4284 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

4311 using ZERO_BASED_SEGMENTS.
4312 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4313 never set segment address for SEG_E2 (.bss) and don't write out
4314 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4315 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4316 definitions, and don't merge tags with non-tags. Check for .bf
4317 rather than just checking whether the second character is b and
4318 the third character is f.
4319 (obj_coff_val): gcc can generate values which we don't handle
4320 correctly; discard information for now, since it only affects the
4321 debugging information.

4323 (yank_symbols): Don't merge labels.
4324 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4470 could be doing emulation.
4472 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4475 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4506 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4507 constant will not fit in an immediate field.
4508 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4545 * Support for i386-sysv.
4546 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4570 * tc-m68k.c (get_num): make it work for all segments, not just the
4573 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

4584 * tc-z8k.c: lots of bug fixes
4586 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4588 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4589 #elif, since it is not supported by old compilers.
4590 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4591 couple of expressions in tc-m68k.c.
4593 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4595 * read.c (cons): If NO_RELOC is defined, use it.

4601 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4602 local labels to start with a .) and set REGISTER_PREFIX to %.
4603 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4605 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4616 * listing.c (debugging_pseudo): Add stabs and stabn as things to
4619 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4621 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4622 sections starting from zero, rather than making them consecutive.
4623 This makes subsequent reloc calculations easier, esp if the object
4624 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4625 allocate lcomm in .data rather than in .bss. It seems that some
4626 tools can't cope with a non-zero sized bss before linkage.
4628 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4630 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
4631 throughout. That enum no longer means what we thought it meant.

4634 "-mno-688[58]1" options.
4636 * tc-m68k.c: Added CPU32 support.

4647 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4649 * Makefile.in (install): if $(tooldir) exists, install as in
4652 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4654 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4655 .word is < -32768 or > 32767. The -J flag causes the error to be
4656 ignored. This is to catch over-sized switches generated by gcc on
4657 systems which don't support the broken .word hack.
4658 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4659 write.c (fixup_segment): check for signed .word overflow if
4660 WARN_SIGNED_OVERFLOW_WORD.
4662 * write.c (fixup_segment): fixed missing parens in expression
4663 checking for byte or word overflow.

4677 * tc-i386.h : new coff defines
4679 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4681 * input-scrub.c (input_scrub_push): call input_file_begin, not
4683 messages.c (as_perror): print ": " between the passed in error and
4684 the strerror, like perror does.
4686 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
4688 * Makefile.in: use gas_target instead of modifying target_cpu.
4689 From Steve Chamberlain:
4690 Makefile.in: Handle m68*-*-coff*.
4691 read.c, read.h: add mult argument to s_space
4693 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4694 Motorola and MIT syntax; gas can now assemble either type of
4696 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
4697 From Steve Chamberlain:
4698 m68kcoff.mt: for m68k COFF.
4699 obj-coffbfd.c: (fixup_mdeps) added
4700 (size_section) removed bad sanity check
4701 (fill_section) added rs_machine_dependent case
4702 (write_object_file) call fixup_mdeps
4703 (fixup_segment) set fx_subsy to 0.
4704 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4706 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4709 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4711 * Makefile.in (LIBS): Include opcode library.
4713 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
4715 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
4716 including zero are accepted, pass +0.0.

4720 * Makefile.in: map "as" through program_transform_name when
4723 * doc/Makefile.in: map "as" through program_transform_name when

4738 * config/tc-m68k.c (init_table): Now const. Always include 68851
4739 data, so that "bc" is available to 68040 cache instructions.
4740 Added "tt0", "tt1", and 68ec030 variants.
4741 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4742 (enum _register): Added TT0, TT1.

4774 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4776 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4777 written with indirection on the last two operands, which can be
4778 either data or address registers. Added a new operand type 'r'
4779 which accepts either register type. Added '(' to notend stuff in
4780 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4826 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
4827 being used with args swapped, causing occasional lossage when
4828 refilling buffers after an include file.

4838 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
4839 selected architecture, print a message saying so and listing what

4890 processor/opcode mismatch, so reword the error message.
4891 (md_assemble): If no CPU has been set (even if FPU/PMMU
4892 characteristics have been), default to 68020. Don't need extra
4893 quotes around error string.

4897 * read.c (potable): Revert sac's incorrect change made Jul 13.

4975 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
4977 * write.c (write_object_file): keep the fix_tail clean, which
4978 fixes a bug in -R where relocations were being lost.

5029 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5031 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5032 where gcc looks for it.

5115 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5116 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5117 copyrights to '92, changed some from Cygnus to FSF.
5119 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5121 * expr.c: If an expression is single comma, then return with
5122 SEG_ABSENT rather than an error - since the sparc front end does
5123 really strange things with things like fbge,a
5125 * as.h: include bfd.h if using many sections
5126 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5127 local labels didn't work.
5128 * listing.c (list_symbol_table): don't core dump when there's no
5130 * write.c, write.h: call fix_new with the right number of args on
5132 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5135 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5137 * app.c: MRI compatibility - allow single quote to start a string.
5138 * as.c: fix typo recently introduced.
5139 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5140 * expr.c: Much rewriting, to accomodate MRI syntax for
5141 expressions. Also easier to read now.
5142 * listing.c: Put back defuns
5143 * read.c: modified to accept MRI syntax, put back listing pseudo
5144 ops so that an assembler built with NO_LISTING ignores list ops
5146 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5147 machine is a SPARC or a 29K.
5148 * config/obj-aout.c: added s_sect pseudo op
5149 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5150 fill in the timestamp.
5151 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5152 anymore, define all the relocs which the tc-<x> bit will use so we
5153 can translate from them to the coff types.
5154 * config/tc-a29k.c: reloc_type isn't ane enum any more
5155 * config/tc-m68k.c: Added NO_RELOC definition.
5157 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5159 * Makefile.in: put header files before C source for TAGS; remove
5160 references to non-existent syscalls.h.
5162 * read.c, write.c subsegs.c: back out the .bss changes.
5164 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5166 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5170 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5172 * symbols.c (local_label_name): symbols now start with ^A.
5174 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5175 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5176 generate these sections. .align: will use NOP_OPCODE or 0
5177 for padding. This is just for being nice to the
5180 * expr.c (operand): changed to generate local label "\001L0"
5181 starting with a ^A so that it is recognized as a local label.
5183 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5185 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5186 i/o opcodes - inb, inw, outb and outw. string manipulation with
5187 att syntax - scmp, slod, smov, ssca, ssto.
5189 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5190 to just after .file .
5192 In obj_crawl_symbol_chain() where it tries to put the external
5193 symbols apart, with the condition:
5194 (!S_IS_DEFINED(symbolP) &&
5195 !S_IS_DEBUG(symbolP) &&
5196 !SF_GET_STATICS(symbolP))
5197 it was moving too many symbols out. So I switch it back to the
5199 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5201 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5202 so that we don't use the F_RELFLG which make the linker complain
5203 that somebody has stripped the relocation info.
5205 Also, the AIX ld program require that the relocation table
5206 is sorted by r_vaddr like the standard ATT assembler does.
5208 [he also changed the sizeof(struct ...)'s into the coff
5209 style FOOSZ macros. I'm not sure this is right, but I can't
5210 remember why. xoxorich.]
5212 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

5221 * configure.in: use the new atof-ns32.c for ns32k.
5223 * write.c: comment change only.
5225 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
