1040 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1041 the table, require that the one without bit 0x1000000 set come
1042 first. Require further that it be case 'b' or 'P'. The a29k
1043 opcode table already meets these constraints.
1044 (machine_ip): When handling case 'i' or 'A', make sure that the

1096 * write.c (write_relocs): For relocs that are pc_relative and
1097 pcrel_offset and not partial_inplace, adjust reloc->addend to

1153 for keeping or rejecting configurations still under development;
1154 default is to assume production environment, and reject configs
1155 still being worked on. Mark Elf configurations (except sparc and
1156 i386) as developmental. Deleted cases matching some generic names
1157 in favor of more specific names. (E.g., when we get Alpha

1174 through inclusion of tc-hppa.h. Delete all forward declarations
1175 for functions only used within tc-hppa.c, likewise for structures,
1176 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1177 conditional code in a few small places.
1179 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1180 structures, global variables, forward declarations together.

1182 conditional code -- try to group conditional code together
1183 into a few places. Make all functions and variables which
1184 are only used within tc-hppa.c static. PARAMize all functions.
1185 Add comments to functions. Delete unused functions, variables,
1186 #defines, etc. Delete unused members within structures. Delete
1187 ldil;ble hacks -- it is believed they were installed to work
1188 around old gas bugs. Avoid using mixed case for local
1189 functions, variables, and structures. Fix formatting problems
1190 not found by GNU-indent. Add FIXME notices for things which
1191 should be worked on the near future. Delete lots of old
1192 useless (1.36 PA-SOM) code.

1209 * config/tc-hppa.c: Likewise.
1211 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1212 of elf32_symbol_type.
1213 (pa_export_args): Likewise.

1221 a multiple of the section alignment rather than always a
1224 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

1265 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1267 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1268 ELF, since the ELF object format does not have these type of
1269 relocations. Change the abort into as as_bad and return
1270 BFD_RELOC_NONE to silence compiler warnings.
1271 (md_assemble): Keep track of the instruction size. Allow white
1272 space between the $ and the constant for compatibility with older
1273 gases and other assemblers.
1274 (i386_operand): Skip spaces between $ and expression.
1275 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

2336 type and to delay the computation of the expression until the
2337 value is actually needed. This permits setting symbols to values
2338 calculated based on object code size. Expressions were changed to
2339 no longer be in a section, to stop the overloading of segment and
2340 expression type that previously occurred.

2544 sy_resolved and sy_resolving single bit fields.
2545 * symbols.c (symbol_new): Don't initialize sy_forward field.

3710 * config/tc-mips.c (macro): Use $AT if target register is zero in
3711 load instruction, which it can be for a floating point load.

3785 prototypes for all static functions. Moved existing minimal
3786 debugging format support info #ifndef OBJ_ECOFF blocks.

3837 * read.c (s_ignore): Don't declare is_end_of_line. It's
3838 redundant, and triggers a VMS gcc compiler bug.
3840 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3841 current segment as an argument. (Ignored in all cases but VMS.)
3842 All callers and definitions changed.

4159 (operand): Treat zero byte as end-of-operand.
4161 * configure.in (per-target): Look for with_bfd_assembler option.
4162 For now, only accept "no", until the merge is done.
4164 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4165 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4166 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4167 * read.c: Finish conversion to S_* macros in the VMS only
4168 parts of the program. Add "const" modifier to hex_value.

4171 * expr.c: Add "const" modifier to hex_value.
4172 * symbols.c: Finish conversion to S_* macros in the VMS only
4173 parts of the program. Add "const" modifier to
4174 md_[long,short]_jump_size. Remove declaration of const_flag
4175 (which will be declared in obj-vms.h).
4176 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4177 Fix arguments to VMS_write_object_file.
4178 * config-gas.com: New file. Script for VMS systems to set up the

4238 mapping to segT enum values.
4239 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4240 if these are used or defined, if BFD_ASSEMBLER.
4241 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

4245 * as.h (volatile): Don't define if already defined.
4246 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4248 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4249 declare with format attribute for -Wformat checking.
4251 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4253 * app.c, config/tc-*.c: Don't include read.h, since it is already
4256 * These are based on patches from Minh Tran-le
4257 <mtranle@paris.intellicorp.com>.
4258 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4259 obj_format coffbfd and gas_target i386coff for target.
4260 (i[34]86-*-isc*): New host (uses sysv).
4261 * config/i386aix.mt: Removed (no longer used).
4262 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4264 (LDFLAGS): Added, defined as -shlib.
4265 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4266 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4267 (DOT_LABEL_PREFIX): Define.
4268 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4269 name rather than L0\001.
4270 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4272 * symbols.c, symbols.h (local_bss_counter): Removed.
4273 * write.c (write_object_file): bss no longer uses
4274 local_bss_counter. Pass correct data and bss size to
4275 VMS_write_object_file.

4279 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
4280 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
4281 (size_section): Restored sanity check.
4282 (do_relocs_for): Base section address on s_paddr rather than
4283 computing it. Adjust a29k R_IHIHALF special case to account for
4284 section paddr (used to require paddr to be zero). If there are no
4285 reclos, set s_relptr to 0. Set relocation size in object_headers.
4286 (fill_section): Always set s_vaddr here, removing
4287 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4288 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4289 Set STYP_INFO for .comment.
4290 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4291 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4293 H_{SET,GET}_* macros.
4294 (do_linenos_for): Set lineno size in object_headers.
4295 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4296 set s_vaddr here. If string_byte_count remains 4, set it back to
4297 0, and only write strings out if there are some. Call
4298 fill_section before do_relocs_for and do_linenos_for.
4299 (obj_coff_section): Handle optional quoted second argument giving
4300 section characteristics.
4301 (obj_coff_bss): Added to handle .bss.
4302 (obj_coff_ident): Added to handle .ident (puts string in .comment
4304 (obj_coff_lcomm): Put common symbols in .bss, not .data.
4305 (fixup_mdeps): Change to segment. Call frag_wane after
4307 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4308 adjustment (already happened only for common symbols, but this is
4310 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

4321 * app.c (app_push): Use memcpy, not bcopy.
4322 (do_scrub_next_char): For \", return " not '.
4323 (symbol_chars): Now const.
4325 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4326 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4328 * config/obj-coff.h: Don't use #elif.
4330 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4331 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4333 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

4357 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4358 using ZERO_BASED_SEGMENTS.
4359 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4360 never set segment address for SEG_E2 (.bss) and don't write out
4361 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4362 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4363 definitions, and don't merge tags with non-tags. Check for .bf
4364 rather than just checking whether the second character is b and
4365 the third character is f.
4366 (obj_coff_val): gcc can generate values which we don't handle
4367 correctly; discard information for now, since it only affects the
4368 debugging information.
4369 (tag_find_or_name): Don't insert tags in the symbol table.
4370 (yank_symbols): Don't merge labels.
4371 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4374 (obj_coff_section): Accept and ignore a trailing quoted string, as
4375 used in AT&T i386 syntax.
4376 (fixup_segment): Take segment as argument. On the i386, adjust PC
4377 relative addends by the segment vaddr.
4378 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
4379 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

4516 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
4517 could be doing emulation.
4519 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4522 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
4525 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
4527 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

4551 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4553 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4554 constant will not fit in an immediate field.
4555 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4557 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

4590 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4592 * Support for i386-sysv.
4593 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4597 (fill_section): Don't set STYP_NOLOAD for .bss section.
4598 (fixup_segment): 386 uses strange common symbol format.

4612 fix i960+non-bfd coff bit rot.
4613 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
4614 support for C source listings. (obj_coff_endef): look in the right

4617 * tc-m68k.c (get_num): make it work for all segments, not just the
4620 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
4622 * configure.in: recognize i386-*-bsd emulation.

4631 * tc-z8k.c: lots of bug fixes
4633 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4635 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4636 #elif, since it is not supported by old compilers.
4637 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4638 couple of expressions in tc-m68k.c.
4640 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4642 * read.c (cons): If NO_RELOC is defined, use it.
4644 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4646 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4648 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4649 local labels to start with a .) and set REGISTER_PREFIX to %.
4650 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4652 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
4654 * messages.c: Comment changes.
4656 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

4659 * messages.c: If __STDC__ is not defined, define NO_STDARG.
4661 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
4663 * listing.c (debugging_pseudo): Add stabs and stabn as things to
4666 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4668 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4669 sections starting from zero, rather than making them consecutive.
4670 This makes subsequent reloc calculations easier, esp if the object
4671 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4672 allocate lcomm in .data rather than in .bss. It seems that some
4673 tools can't cope with a non-zero sized bss before linkage.
4675 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4677 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
4678 throughout. That enum no longer means what we thought it meant.
4680 * tc-m68k.c (md_assemble, md_parse_option): Handle new
4681 "-mno-688[58]1" options.
4683 * tc-m68k.c: Added CPU32 support.
4685 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4687 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.

4691 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
4692 Change LIBDEPS dependence to LIBS.
4694 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4696 * Makefile.in (install): if $(tooldir) exists, install as in
4699 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4701 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4702 .word is < -32768 or > 32767. The -J flag causes the error to be
4703 ignored. This is to catch over-sized switches generated by gcc on
4704 systems which don't support the broken .word hack.
4705 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4706 write.c (fixup_segment): check for signed .word overflow if
4707 WARN_SIGNED_OVERFLOW_WORD.
4709 * write.c (fixup_segment): fixed missing parens in expression
4710 checking for byte or word overflow.
4712 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
4713 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
4714 WARN_SIGNED_OVERFLOW_WORD.

5194 machine is a SPARC or a 29K.
5195 * config/obj-aout.c: added s_sect pseudo op
5196 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5197 fill in the timestamp.
5198 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5199 anymore, define all the relocs which the tc-<x> bit will use so we

5219 * symbols.c (local_label_name): symbols now start with ^A.
5221 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5222 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5223 generate these sections. .align: will use NOP_OPCODE or 0
5224 for padding. This is just for being nice to the
5227 * expr.c (operand): changed to generate local label "\001L0"
5228 starting with a ^A so that it is recognized as a local label.
5230 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5232 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5233 i/o opcodes - inb, inw, outb and outw. string manipulation with
5234 att syntax - scmp, slod, smov, ssca, ssto.
5236 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5237 to just after .file .
5239 In obj_crawl_symbol_chain() where it tries to put the external
5240 symbols apart, with the condition:
5241 (!S_IS_DEFINED(symbolP) &&
5242 !S_IS_DEBUG(symbolP) &&
5243 !SF_GET_STATICS(symbolP))
5244 it was moving too many symbols out. So I switch it back to the
5246 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5248 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5249 so that we don't use the F_RELFLG which make the linker complain
5250 that somebody has stripped the relocation info.
5252 Also, the AIX ld program require that the relocation table
5253 is sorted by r_vaddr like the standard ATT assembler does.
5255 [he also changed the sizeof(struct ...)'s into the coff
5256 style FOOSZ macros. I'm not sure this is right, but I can't
5257 remember why. xoxorich.]

5261 * Makefile.in, configure.in, doc: use the doc. Build it, install
5264 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5266 * read.c: white space and comments only.
5268 * configure.in: use the new atof-ns32.c for ns32k.
5270 * write.c: comment change only.
5272 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5273 aren't yet integrated.
5275 * tc-i860.[hc]: blew off the dust. Something must still be done
5276 about conflicting relocation types.
5278 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5281 * tc-i960.c, tc-sparc.c: white space and comments only.
5283 * tc-a29k.h: delete duplicate macro definition.
5285 * new file atof-ns32k.c copied from hack's last unreleased gas.
5287 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5289 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5292 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5293 ChangeLog's prior to this are sketchy at best. I have logs.
5294 They just aren't ChangeLogs.
