1003 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1004 the table, require that the one without bit 0x1000000 set come
1005 first. Require further that it be case 'b' or 'P'. The a29k

1059 * write.c (write_relocs): For relocs that are pc_relative and
1060 pcrel_offset and not partial_inplace, adjust reloc->addend to

1115 * configure.in: Set bfd_gas for all sparc targets. Added facility
1116 for keeping or rejecting configurations still under development;
1117 default is to assume production environment, and reject configs
1118 still being worked on. Mark Elf configurations (except sparc and
1119 i386) as developmental. Deleted cases matching some generic names
1120 in favor of more specific names. (E.g., when we get Alpha

1137 through inclusion of tc-hppa.h. Delete all forward declarations
1138 for functions only used within tc-hppa.c, likewise for structures,
1139 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1140 conditional code in a few small places.
1142 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1143 structures, global variables, forward declarations together.

1145 conditional code -- try to group conditional code together
1146 into a few places. Make all functions and variables which
1147 are only used within tc-hppa.c static. PARAMize all functions.
1148 Add comments to functions. Delete unused functions, variables,
1149 #defines, etc. Delete unused members within structures. Delete
1150 ldil;ble hacks -- it is believed they were installed to work
1151 around old gas bugs. Avoid using mixed case for local
1152 functions, variables, and structures. Fix formatting problems
1153 not found by GNU-indent. Add FIXME notices for things which
1154 should be worked on the near future. Delete lots of old
1155 useless (1.36 PA-SOM) code.

1172 * config/tc-hppa.c: Likewise.
1174 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1175 of elf32_symbol_type.
1176 (pa_export_args): Likewise.

1183 * config/tc-hppa.c: (md_section_align): Align all sections to
1184 a multiple of the section alignment rather than always a
1187 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

1228 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1230 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1231 ELF, since the ELF object format does not have these type of
1232 relocations. Change the abort into as as_bad and return
1233 BFD_RELOC_NONE to silence compiler warnings.
1234 (md_assemble): Keep track of the instruction size. Allow white
1235 space between the $ and the constant for compatibility with older
1236 gases and other assemblers.
1237 (i386_operand): Skip spaces between $ and expression.
1238 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

3625 avoid some redefinition complaints on some systems.

3673 * config/tc-mips.c (macro): Use $AT if target register is zero in
3674 load instruction, which it can be for a floating point load.

3697 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3699 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

3748 prototypes for all static functions. Moved existing minimal
3749 debugging format support info #ifndef OBJ_ECOFF blocks.

3798 * make-gas.com: Find obstack.obj if it's not in the current
3800 * read.c (s_ignore): Don't declare is_end_of_line. It's
3801 redundant, and triggers a VMS gcc compiler bug.

4122 (operand): Treat zero byte as end-of-operand.
4124 * configure.in (per-target): Look for with_bfd_assembler option.
4125 For now, only accept "no", until the merge is done.
4127 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4128 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4134 * expr.c: Add "const" modifier to hex_value.
4135 * symbols.c: Finish conversion to S_* macros in the VMS only

4137 md_[long,short]_jump_size. Remove declaration of const_flag
4138 (which will be declared in obj-vms.h).
4139 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4140 Fix arguments to VMS_write_object_file.
4141 * config-gas.com: New file. Script for VMS systems to set up the

4201 mapping to segT enum values.
4202 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4203 if these are used or defined, if BFD_ASSEMBLER.
4204 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4205 subseg_new split into two functions.
4206 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4208 * as.h (volatile): Don't define if already defined.
4209 (had_errors, had_warnings): Provide prototypes for ANSI C even if

4233 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4235 * symbols.c, symbols.h (local_bss_counter): Removed.
4236 * write.c (write_object_file): bss no longer uses
4237 local_bss_counter. Pass correct data and bss size to
4238 VMS_write_object_file.
4239 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
4240 argument, rather than using local_bss_counter.

4244 (size_section): Restored sanity check.
4245 (do_relocs_for): Base section address on s_paddr rather than
4246 computing it. Adjust a29k R_IHIHALF special case to account for
4247 section paddr (used to require paddr to be zero). If there are no
4248 reclos, set s_relptr to 0. Set relocation size in object_headers.
4249 (fill_section): Always set s_vaddr here, removing
4250 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4251 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4252 Set STYP_INFO for .comment.
4253 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4254 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4256 H_{SET,GET}_* macros.
4257 (do_linenos_for): Set lineno size in object_headers.
4258 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4259 set s_vaddr here. If string_byte_count remains 4, set it back to
4260 0, and only write strings out if there are some. Call
4261 fill_section before do_relocs_for and do_linenos_for.
4262 (obj_coff_section): Handle optional quoted second argument giving
4263 section characteristics.
4264 (obj_coff_bss): Added to handle .bss.
4265 (obj_coff_ident): Added to handle .ident (puts string in .comment
4267 (obj_coff_lcomm): Put common symbols in .bss, not .data.
4268 (fixup_mdeps): Change to segment. Call frag_wane after
4270 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4271 adjustment (already happened only for common symbols, but this is
4273 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
4274 * config/tc-i386.c (s_bss): Don't use if I386COFF.

4282 Mon Dec 28 10:32:05 1992 Ken Raeburn (raeburn@cygnus.com)
4284 * app.c (app_push): Use memcpy, not bcopy.
4285 (do_scrub_next_char): For \", return " not '.
4286 (symbol_chars): Now const.
4288 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4289 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4291 * config/obj-coff.h: Don't use #elif.
4293 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4294 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4296 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

4320 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4321 using ZERO_BASED_SEGMENTS.
4322 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4323 never set segment address for SEG_E2 (.bss) and don't write out
4324 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4325 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4326 definitions, and don't merge tags with non-tags. Check for .bf
4327 rather than just checking whether the second character is b and
4328 the third character is f.
4329 (obj_coff_val): gcc can generate values which we don't handle
4330 correctly; discard information for now, since it only affects the
4331 debugging information.
4332 (tag_find_or_name): Don't insert tags in the symbol table.
4333 (yank_symbols): Don't merge labels.
4334 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4336 set segment address if ZERO_BASED_SEGMENTS.
4337 (obj_coff_section): Accept and ignore a trailing quoted string, as
4338 used in AT&T i386 syntax.
4339 (fixup_segment): Take segment as argument. On the i386, adjust PC
4340 relative addends by the segment vaddr.

4444 xrealloc from xrealloc.c.
4445 * xrealloc.c: Deleted.
4446 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.

4479 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
4480 could be doing emulation.
4482 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4485 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
4488 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

4514 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4516 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4517 constant will not fit in an immediate field.
4518 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4553 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4555 * Support for i386-sysv.
4556 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4580 * tc-m68k.c (get_num): make it work for all segments, not just the
4583 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

4594 * tc-z8k.c: lots of bug fixes
4596 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4598 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4599 #elif, since it is not supported by old compilers.
4600 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4601 couple of expressions in tc-m68k.c.
4603 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4605 * read.c (cons): If NO_RELOC is defined, use it.
4607 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4609 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4611 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4612 local labels to start with a .) and set REGISTER_PREFIX to %.
4613 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4615 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
4617 * messages.c: Comment changes.
4619 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

4622 * messages.c: If __STDC__ is not defined, define NO_STDARG.
4624 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
4626 * listing.c (debugging_pseudo): Add stabs and stabn as things to
4629 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4631 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4632 sections starting from zero, rather than making them consecutive.
4633 This makes subsequent reloc calculations easier, esp if the object
4634 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4635 allocate lcomm in .data rather than in .bss. It seems that some
4636 tools can't cope with a non-zero sized bss before linkage.
4638 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4640 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
4641 throughout. That enum no longer means what we thought it meant.
4643 * tc-m68k.c (md_assemble, md_parse_option): Handle new
4644 "-mno-688[58]1" options.
4646 * tc-m68k.c: Added CPU32 support.

4655 Change LIBDEPS dependence to LIBS.
4657 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4659 * Makefile.in (install): if $(tooldir) exists, install as in
4662 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4664 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4665 .word is < -32768 or > 32767. The -J flag causes the error to be
4666 ignored. This is to catch over-sized switches generated by gcc on
4667 systems which don't support the broken .word hack.
4668 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4669 write.c (fixup_segment): check for signed .word overflow if
4670 WARN_SIGNED_OVERFLOW_WORD.
4672 * write.c (fixup_segment): fixed missing parens in expression
4673 checking for byte or word overflow.
4675 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

4687 * tc-i386.h : new coff defines
4689 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4691 * input-scrub.c (input_scrub_push): call input_file_begin, not
4693 messages.c (as_perror): print ": " between the passed in error and
4694 the strerror, like perror does.
4696 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
4698 * Makefile.in: use gas_target instead of modifying target_cpu.
4699 From Steve Chamberlain:
4700 Makefile.in: Handle m68*-*-coff*.
4701 read.c, read.h: add mult argument to s_space
4703 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4704 Motorola and MIT syntax; gas can now assemble either type of
4706 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
4707 From Steve Chamberlain:
4708 m68kcoff.mt: for m68k COFF.
4709 obj-coffbfd.c: (fixup_mdeps) added
4710 (size_section) removed bad sanity check
4711 (fill_section) added rs_machine_dependent case
4712 (write_object_file) call fixup_mdeps
4713 (fixup_segment) set fx_subsy to 0.
4714 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4716 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala

4748 * config/tc-m68k.c (init_table): Now const. Always include 68851
4749 data, so that "bc" is available to 68040 cache instructions.
4750 Added "tt0", "tt1", and 68ec030 variants.
4751 (md_assemble): Complain if 68000 (only) and 68881 are specified.

4784 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4786 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4787 written with indirection on the last two operands, which can be
4788 either data or address registers. Added a new operand type 'r'
4789 which accepts either register type. Added '(' to notend stuff in
4790 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4837 being used with args swapped, causing occasional lossage when
4838 refilling buffers after an include file.

4900 processor/opcode mismatch, so reword the error message.
4901 (md_assemble): If no CPU has been set (even if FPU/PMMU
4902 characteristics have been), default to 68020. Don't need extra
4903 quotes around error string.

4985 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
4987 * write.c (write_object_file): keep the fix_tail clean, which
4988 fixes a bug in -R where relocations were being lost.

5039 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5041 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5042 where gcc looks for it.

5125 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5126 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5127 copyrights to '92, changed some from Cygnus to FSF.
5129 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5131 * expr.c: If an expression is single comma, then return with
5132 SEG_ABSENT rather than an error - since the sparc front end does
5133 really strange things with things like fbge,a
5135 * as.h: include bfd.h if using many sections
5136 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5137 local labels didn't work.
5138 * listing.c (list_symbol_table): don't core dump when there's no
5140 * write.c, write.h: call fix_new with the right number of args on
5142 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5145 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5147 * app.c: MRI compatibility - allow single quote to start a string.
5148 * as.c: fix typo recently introduced.
5149 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5150 * expr.c: Much rewriting, to accomodate MRI syntax for
5151 expressions. Also easier to read now.
5152 * listing.c: Put back defuns
5153 * read.c: modified to accept MRI syntax, put back listing pseudo
5154 ops so that an assembler built with NO_LISTING ignores list ops
5156 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5157 machine is a SPARC or a 29K.
5158 * config/obj-aout.c: added s_sect pseudo op
5159 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5160 fill in the timestamp.
5161 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5162 anymore, define all the relocs which the tc-<x> bit will use so we
5163 can translate from them to the coff types.
5164 * config/tc-a29k.c: reloc_type isn't ane enum any more
5165 * config/tc-m68k.c: Added NO_RELOC definition.
5167 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5169 * Makefile.in: put header files before C source for TAGS; remove
5170 references to non-existent syscalls.h.
5172 * read.c, write.c subsegs.c: back out the .bss changes.
5174 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5176 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5180 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5182 * symbols.c (local_label_name): symbols now start with ^A.
5184 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5185 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5186 generate these sections. .align: will use NOP_OPCODE or 0
5187 for padding. This is just for being nice to the
5190 * expr.c (operand): changed to generate local label "\001L0"
5191 starting with a ^A so that it is recognized as a local label.
5193 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5195 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5196 i/o opcodes - inb, inw, outb and outw. string manipulation with
5197 att syntax - scmp, slod, smov, ssca, ssto.
5199 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5200 to just after .file .
5202 In obj_crawl_symbol_chain() where it tries to put the external
5203 symbols apart, with the condition:
5204 (!S_IS_DEFINED(symbolP) &&
5205 !S_IS_DEBUG(symbolP) &&
5206 !SF_GET_STATICS(symbolP))
5207 it was moving too many symbols out. So I switch it back to the
5209 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5211 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5212 so that we don't use the F_RELFLG which make the linker complain
5213 that somebody has stripped the relocation info.
5215 Also, the AIX ld program require that the relocation table
5216 is sorted by r_vaddr like the standard ATT assembler does.
5218 [he also changed the sizeof(struct ...)'s into the coff

5224 * Makefile.in, configure.in, doc: use the doc. Build it, install
5227 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5229 * read.c: white space and comments only.
5231 * configure.in: use the new atof-ns32.c for ns32k.
5233 * write.c: comment change only.
5235 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5236 aren't yet integrated.
5238 * tc-i860.[hc]: blew off the dust. Something must still be done
5239 about conflicting relocation types.
5241 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5244 * tc-i960.c, tc-sparc.c: white space and comments only.
5246 * tc-a29k.h: delete duplicate macro definition.
5248 * new file atof-ns32k.c copied from hack's last unreleased gas.

5252 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5255 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5256 ChangeLog's prior to this are sketchy at best. I have logs.
5257 They just aren't ChangeLogs.
