1022 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1023 the table, require that the one without bit 0x1000000 set come
1024 first. Require further that it be case 'b' or 'P'. The a29k

1078 * write.c (write_relocs): For relocs that are pc_relative and
1079 pcrel_offset and not partial_inplace, adjust reloc->addend to

1135 for keeping or rejecting configurations still under development;
1136 default is to assume production environment, and reject configs
1137 still being worked on. Mark Elf configurations (except sparc and
1138 i386) as developmental. Deleted cases matching some generic names
1139 in favor of more specific names. (E.g., when we get Alpha

1156 through inclusion of tc-hppa.h. Delete all forward declarations
1157 for functions only used within tc-hppa.c, likewise for structures,
1158 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1159 conditional code in a few small places.

1164 conditional code -- try to group conditional code together
1165 into a few places. Make all functions and variables which
1166 are only used within tc-hppa.c static. PARAMize all functions.
1167 Add comments to functions. Delete unused functions, variables,
1168 #defines, etc. Delete unused members within structures. Delete
1169 ldil;ble hacks -- it is believed they were installed to work
1170 around old gas bugs. Avoid using mixed case for local
1171 functions, variables, and structures. Fix formatting problems
1172 not found by GNU-indent. Add FIXME notices for things which
1173 should be worked on the near future. Delete lots of old
1174 useless (1.36 PA-SOM) code.

1193 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1194 of elf32_symbol_type.
1195 (pa_export_args): Likewise.

1203 a multiple of the section alignment rather than always a
1206 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

1247 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1249 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1250 ELF, since the ELF object format does not have these type of
1251 relocations. Change the abort into as as_bad and return
1252 BFD_RELOC_NONE to silence compiler warnings.
1253 (md_assemble): Keep track of the instruction size. Allow white
1254 space between the $ and the constant for compatibility with older
1255 gases and other assemblers.
1256 (i386_operand): Skip spaces between $ and expression.
1257 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

3692 * config/tc-mips.c (macro): Use $AT if target register is zero in
3693 load instruction, which it can be for a floating point load.

3767 prototypes for all static functions. Moved existing minimal
3768 debugging format support info #ifndef OBJ_ECOFF blocks.

3817 * make-gas.com: Find obstack.obj if it's not in the current
3819 * read.c (s_ignore): Don't declare is_end_of_line. It's
3820 redundant, and triggers a VMS gcc compiler bug.
3822 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3823 current segment as an argument. (Ignored in all cases but VMS.)

4141 (operand): Treat zero byte as end-of-operand.
4143 * configure.in (per-target): Look for with_bfd_assembler option.
4144 For now, only accept "no", until the merge is done.
4146 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4147 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4153 * expr.c: Add "const" modifier to hex_value.
4154 * symbols.c: Finish conversion to S_* macros in the VMS only
4155 parts of the program. Add "const" modifier to
4156 md_[long,short]_jump_size. Remove declaration of const_flag
4157 (which will be declared in obj-vms.h).
4158 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4159 Fix arguments to VMS_write_object_file.
4160 * config-gas.com: New file. Script for VMS systems to set up the

4177 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4178 as symbols as well in the object file. Look for external functions

4192 (s_lcomm): Likewise with bss_section.
4193 (s_fill): Use memset, not bzero.
4195 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4219 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4220 mapping to segT enum values.
4221 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4222 if these are used or defined, if BFD_ASSEMBLER.
4223 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4224 subseg_new split into two functions.
4225 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4227 * as.h (volatile): Don't define if already defined.
4228 (had_errors, had_warnings): Provide prototypes for ANSI C even if

4235 * app.c, config/tc-*.c: Don't include read.h, since it is already
4238 * These are based on patches from Minh Tran-le
4239 <mtranle@paris.intellicorp.com>.
4240 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4241 obj_format coffbfd and gas_target i386coff for target.
4242 (i[34]86-*-isc*): New host (uses sysv).
4243 * config/i386aix.mt: Removed (no longer used).
4244 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4246 (LDFLAGS): Added, defined as -shlib.
4247 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4248 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4249 (DOT_LABEL_PREFIX): Define.
4250 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4251 name rather than L0\001.
4252 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4254 * symbols.c, symbols.h (local_bss_counter): Removed.
4255 * write.c (write_object_file): bss no longer uses
4256 local_bss_counter. Pass correct data and bss size to
4257 VMS_write_object_file.
4258 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
4259 argument, rather than using local_bss_counter.

4261 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
4262 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
4263 (size_section): Restored sanity check.
4264 (do_relocs_for): Base section address on s_paddr rather than
4265 computing it. Adjust a29k R_IHIHALF special case to account for
4266 section paddr (used to require paddr to be zero). If there are no
4267 reclos, set s_relptr to 0. Set relocation size in object_headers.
4268 (fill_section): Always set s_vaddr here, removing
4269 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4270 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4271 Set STYP_INFO for .comment.
4272 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4273 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4275 H_{SET,GET}_* macros.
4276 (do_linenos_for): Set lineno size in object_headers.
4277 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4278 set s_vaddr here. If string_byte_count remains 4, set it back to
4279 0, and only write strings out if there are some. Call
4280 fill_section before do_relocs_for and do_linenos_for.
4281 (obj_coff_section): Handle optional quoted second argument giving
4282 section characteristics.
4283 (obj_coff_bss): Added to handle .bss.
4284 (obj_coff_ident): Added to handle .ident (puts string in .comment
4286 (obj_coff_lcomm): Put common symbols in .bss, not .data.
4287 (fixup_mdeps): Change to segment. Call frag_wane after
4289 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4290 adjustment (already happened only for common symbols, but this is
4292 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
4293 * config/tc-i386.c (s_bss): Don't use if I386COFF.

4301 Mon Dec 28 10:32:05 1992 Ken Raeburn (raeburn@cygnus.com)
4303 * app.c (app_push): Use memcpy, not bcopy.
4304 (do_scrub_next_char): For \", return " not '.
4305 (symbol_chars): Now const.
4307 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4308 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4310 * config/obj-coff.h: Don't use #elif.
4312 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4313 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

4339 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4340 using ZERO_BASED_SEGMENTS.
4341 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4342 never set segment address for SEG_E2 (.bss) and don't write out
4343 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4344 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4345 definitions, and don't merge tags with non-tags. Check for .bf
4346 rather than just checking whether the second character is b and
4347 the third character is f.
4348 (obj_coff_val): gcc can generate values which we don't handle
4349 correctly; discard information for now, since it only affects the
4350 debugging information.
4351 (tag_find_or_name): Don't insert tags in the symbol table.
4352 (yank_symbols): Don't merge labels.
4353 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4356 (obj_coff_section): Accept and ignore a trailing quoted string, as
4357 used in AT&T i386 syntax.
4358 (fixup_segment): Take segment as argument. On the i386, adjust PC
4359 relative addends by the segment vaddr.
4360 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
4361 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

4499 could be doing emulation.
4501 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4504 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4535 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4536 constant will not fit in an immediate field.
4537 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4572 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4574 * Support for i386-sysv.
4575 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4599 * tc-m68k.c (get_num): make it work for all segments, not just the
4602 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
4604 * configure.in: recognize i386-*-bsd emulation.

4613 * tc-z8k.c: lots of bug fixes
4615 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4617 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4618 #elif, since it is not supported by old compilers.
4619 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4620 couple of expressions in tc-m68k.c.
4622 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4624 * read.c (cons): If NO_RELOC is defined, use it.
4626 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4628 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4630 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4631 local labels to start with a .) and set REGISTER_PREFIX to %.
4632 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4634 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
4636 * messages.c: Comment changes.
4638 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

4641 * messages.c: If __STDC__ is not defined, define NO_STDARG.
4643 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
4645 * listing.c (debugging_pseudo): Add stabs and stabn as things to
4648 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4650 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4651 sections starting from zero, rather than making them consecutive.
4652 This makes subsequent reloc calculations easier, esp if the object
4653 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4654 allocate lcomm in .data rather than in .bss. It seems that some
4655 tools can't cope with a non-zero sized bss before linkage.
4657 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4659 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
4660 throughout. That enum no longer means what we thought it meant.
4662 * tc-m68k.c (md_assemble, md_parse_option): Handle new
4663 "-mno-688[58]1" options.
4665 * tc-m68k.c: Added CPU32 support.

4673 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
4674 Change LIBDEPS dependence to LIBS.
4676 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4678 * Makefile.in (install): if $(tooldir) exists, install as in
4681 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4683 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4684 .word is < -32768 or > 32767. The -J flag causes the error to be
4685 ignored. This is to catch over-sized switches generated by gcc on
4686 systems which don't support the broken .word hack.
4687 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4688 write.c (fixup_segment): check for signed .word overflow if
4689 WARN_SIGNED_OVERFLOW_WORD.
4691 * write.c (fixup_segment): fixed missing parens in expression
4692 checking for byte or word overflow.
4694 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

4705 * tc-i386.c (tc_coff_fix2rtype): new function
4706 * tc-i386.h : new coff defines
4708 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4710 * input-scrub.c (input_scrub_push): call input_file_begin, not
4712 messages.c (as_perror): print ": " between the passed in error and
4713 the strerror, like perror does.
4715 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
4717 * Makefile.in: use gas_target instead of modifying target_cpu.
4718 From Steve Chamberlain:

4805 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4806 written with indirection on the last two operands, which can be
4807 either data or address registers. Added a new operand type 'r'
4808 which accepts either register type. Added '(' to notend stuff in
4809 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5152 really strange things with things like fbge,a
5154 * as.h: include bfd.h if using many sections
5155 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

5164 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5166 * app.c: MRI compatibility - allow single quote to start a string.

5169 * expr.c: Much rewriting, to accomodate MRI syntax for
5170 expressions. Also easier to read now.
5171 * listing.c: Put back defuns
5172 * read.c: modified to accept MRI syntax, put back listing pseudo
5173 ops so that an assembler built with NO_LISTING ignores list ops
5175 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5176 machine is a SPARC or a 29K.
5177 * config/obj-aout.c: added s_sect pseudo op
5178 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5179 fill in the timestamp.
5180 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5181 anymore, define all the relocs which the tc-<x> bit will use so we
5182 can translate from them to the coff types.
5183 * config/tc-a29k.c: reloc_type isn't ane enum any more
5184 * config/tc-m68k.c: Added NO_RELOC definition.

5203 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5204 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5205 generate these sections. .align: will use NOP_OPCODE or 0
5206 for padding. This is just for being nice to the
5209 * expr.c (operand): changed to generate local label "\001L0"
5210 starting with a ^A so that it is recognized as a local label.
5212 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5214 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5215 i/o opcodes - inb, inw, outb and outw. string manipulation with
5216 att syntax - scmp, slod, smov, ssca, ssto.
5218 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5219 to just after .file .
5221 In obj_crawl_symbol_chain() where it tries to put the external
5222 symbols apart, with the condition:
5223 (!S_IS_DEFINED(symbolP) &&
5224 !S_IS_DEBUG(symbolP) &&
5225 !SF_GET_STATICS(symbolP))
5226 it was moving too many symbols out. So I switch it back to the
5228 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5230 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5231 so that we don't use the F_RELFLG which make the linker complain
5232 that somebody has stripped the relocation info.
5234 Also, the AIX ld program require that the relocation table
5235 is sorted by r_vaddr like the standard ATT assembler does.
5237 [he also changed the sizeof(struct ...)'s into the coff
5238 style FOOSZ macros. I'm not sure this is right, but I can't
5239 remember why. xoxorich.]

5243 * Makefile.in, configure.in, doc: use the doc. Build it, install
5246 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5248 * read.c: white space and comments only.
5250 * configure.in: use the new atof-ns32.c for ns32k.
5252 * write.c: comment change only.
5254 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5255 aren't yet integrated.
5257 * tc-i860.[hc]: blew off the dust. Something must still be done
5258 about conflicting relocation types.
5260 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5263 * tc-i960.c, tc-sparc.c: white space and comments only.
5265 * tc-a29k.h: delete duplicate macro definition.
5267 * new file atof-ns32k.c copied from hack's last unreleased gas.

5271 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5274 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5275 ChangeLog's prior to this are sketchy at best. I have logs.
5276 They just aren't ChangeLogs.
