1361 i386) as developmental. Deleted cases matching some generic names
1362 in favor of more specific names. (E.g., when we get Alpha

1390 Add comments to functions. Delete unused functions, variables,
1391 #defines, etc. Delete unused members within structures. Delete
1392 ldil;ble hacks -- it is believed they were installed to work
1393 around old gas bugs. Avoid using mixed case for local
1394 functions, variables, and structures. Fix formatting problems
1395 not found by GNU-indent. Add FIXME notices for things which
1396 should be worked on the near future. Delete lots of old

2540 * Extensive changes to permit symbols to contain any expression
2541 type and to delay the computation of the expression until the
2542 value is actually needed. This permits setting symbols to values
2543 calculated based on object code size. Expressions were changed to
2544 no longer be in a section, to stop the overloading of segment and
2545 expression type that previously occurred.
2547 * as.c (big_section, pass1_section, diff_section, absent_section):
2549 (expr_section): Added (used for dummy symbols which hold

2635 to pop back to it. Handle unquoted section name as well as quoted
2636 section name. Don't crash on invalid strings.

2749 sy_resolved and sy_resolving single bit fields.
2750 * symbols.c (symbol_new): Don't initialize sy_forward field.

3786 * doc/as.texinfo: First pass at using new texinfo features --
3787 variables, conditional tests. Far from complete.

3863 process relocs if there aren't any relocs to process. Avoids
3864 malloc/free bug on SCO too.

3867 avoid some redefinition complaints on some systems.
3868 (const, volatile): Don't need these conditionally defined if we
3869 use CONST and VOLATILE from ansidecl.h.
3870 (seg_name): Use CONST, not const.
3872 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3874 * config/tc-mips.c: Reindented to GNU standards.

3878 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3879 (fixup_segment): Add a29k special case; the linker is not prepared
3880 to see a segment offset here.

3885 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3887 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3903 bignums, but don't emit error message.
3905 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3907 * Makefile.in (targ-cpu.o): Depend on config.h.
3909 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3911 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3912 dropping a space immediately following an identifier.
3913 * expr.c, write.c: Rewrote assert expressions to not use multiple
3914 lines; I don't think that can be done portably.
3915 * config/tc-mips.c (macro): Use $AT if target register is zero in
3916 load instruction, which it can be for a floating point load.
3918 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3939 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3941 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3942 to be on a single line.

3990 prototypes for all static functions. Moved existing minimal
3991 debugging format support info #ifndef OBJ_ECOFF blocks.

3994 all callers accordingly.
3995 (tc_get_register): Renamed from get_register, and made non-static.
3997 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4040 * make-gas.com: Find obstack.obj if it's not in the current
4042 * read.c (s_ignore): Don't declare is_end_of_line. It's
4043 redundant, and triggers a VMS gcc compiler bug.
4045 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4046 current segment as an argument. (Ignored in all cases but VMS.)
4047 All callers and definitions changed.

4344 md_relax_table): Use default zero initialization.
4345 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4346 latter, instead of selecting with preprocessor conditionals.
4348 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4350 * configure.in: recognise all sparclite variants

4360 * expr.c (operand): If character other than comma or newline is a
4361 logical end-of-line character, use the newline case.
4362 From Eric Youngdale:
4363 (operand): Set X_add_number field for floating-point numbers.
4364 (operand): Treat zero byte as end-of-operand.
4366 * configure.in (per-target): Look for with_bfd_assembler option.
4367 For now, only accept "no", until the merge is done.
4369 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4370 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4376 * expr.c: Add "const" modifier to hex_value.
4377 * symbols.c: Finish conversion to S_* macros in the VMS only
4378 parts of the program. Add "const" modifier to
4379 md_[long,short]_jump_size. Remove declaration of const_flag
4380 (which will be declared in obj-vms.h).
4381 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4382 Fix arguments to VMS_write_object_file.
4383 * config-gas.com: New file. Script for VMS systems to set up the
4384 configuration to build gas for VMS, and create config.status.
4385 * make-gas.com: Redone to work with new scheme.
4386 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4388 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4389 will swap bytes if needed on a big endian system. Use throughout
4391 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4392 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4393 types of malformed stabs. Change parsing algorithm so that we are
4394 more certain of having all of the information that we need on hand.
4395 * obj-vms.c (final_forward_reference): New function, used to help
4396 resolve the data types of as many struct elements as possible
4397 when some part of the struct is not fully defined by the compiler.

4400 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4401 as symbols as well in the object file. Look for external functions
4402 that start with "__vt.", and turn them into variables, since the
4403 g++ compiler is incapable of doing this.
4404 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4406 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4407 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4408 have the name of the source file yet.
4409 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4411 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4413 * read.c (s_data): Always use "data_section", since it'll map to
4414 SEG_DATA or SEG_E1 if needed.
4415 (s_lcomm): Likewise with bss_section.
4416 (s_fill): Use memset, not bzero.
4418 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4439 (section_alignment): Declare only if not BFD_ASSEMBLER.
4440 (big_section, reg_section, pass1_section, diff_section,
4441 absent_section, text_section, data_section, bss_section): If
4442 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4443 mapping to segT enum values.
4444 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4445 if these are used or defined, if BFD_ASSEMBLER.
4446 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4447 subseg_new split into two functions.
4448 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4450 * as.h (volatile): Don't define if already defined.
4451 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4453 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4454 declare with format attribute for -Wformat checking.
4456 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4458 * app.c, config/tc-*.c: Don't include read.h, since it is already
4461 * These are based on patches from Minh Tran-le
4462 <mtranle@paris.intellicorp.com>.
4463 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4464 obj_format coffbfd and gas_target i386coff for target.
4465 (i[34]86-*-isc*): New host (uses sysv).
4466 * config/i386aix.mt: Removed (no longer used).
4467 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4469 (LDFLAGS): Added, defined as -shlib.
4470 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4471 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4472 (DOT_LABEL_PREFIX): Define.
4473 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4474 name rather than L0\001.
4475 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4477 * symbols.c, symbols.h (local_bss_counter): Removed.
4478 * write.c (write_object_file): bss no longer uses
4479 local_bss_counter. Pass correct data and bss size to

4486 (size_section): Restored sanity check.
4487 (do_relocs_for): Base section address on s_paddr rather than
4488 computing it. Adjust a29k R_IHIHALF special case to account for
4489 section paddr (used to require paddr to be zero). If there are no
4490 reclos, set s_relptr to 0. Set relocation size in object_headers.
4491 (fill_section): Always set s_vaddr here, removing
4492 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4493 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4494 Set STYP_INFO for .comment.
4495 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4496 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4498 H_{SET,GET}_* macros.
4499 (do_linenos_for): Set lineno size in object_headers.
4500 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4501 set s_vaddr here. If string_byte_count remains 4, set it back to
4502 0, and only write strings out if there are some. Call
4503 fill_section before do_relocs_for and do_linenos_for.
4504 (obj_coff_section): Handle optional quoted second argument giving
4505 section characteristics.
4506 (obj_coff_bss): Added to handle .bss.
4507 (obj_coff_ident): Added to handle .ident (puts string in .comment

4527 (do_scrub_next_char): For \", return " not '.
4528 (symbol_chars): Now const.
4530 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4531 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4533 * config/obj-coff.h: Don't use #elif.
4535 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4536 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4538 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4540 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4560 SEG_BSS, fill with NOP_OPCODE.
4561 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4562 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4563 using ZERO_BASED_SEGMENTS.
4564 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4565 never set segment address for SEG_E2 (.bss) and don't write out
4566 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4567 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4568 definitions, and don't merge tags with non-tags. Check for .bf
4569 rather than just checking whether the second character is b and
4570 the third character is f.
4571 (obj_coff_val): gcc can generate values which we don't handle
4572 correctly; discard information for now, since it only affects the
4573 debugging information.
4574 (tag_find_or_name): Don't insert tags in the symbol table.
4575 (yank_symbols): Don't merge labels.
4576 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4721 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
4722 could be doing emulation.
4724 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4727 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4754 consistently const, and always initialized them. Included read.h.
4756 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4758 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4759 constant will not fit in an immediate field.
4760 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4762 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

4779 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
4780 so widening works consistently.
4782 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
4784 * version.c: Put conditional "const" before version_string, not

4788 printed rep of null character.
4790 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
4792 * obj-coffbfd.c (write_object_file): check return value of
4795 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4797 * Support for i386-sysv.
4798 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
4799 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4800 be used to set them all to zero as was done before.

4802 (fill_section): Don't set STYP_NOLOAD for .bss section.
4803 (fixup_segment): 386 uses strange common symbol format.

4840 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4841 #elif, since it is not supported by old compilers.
4842 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4843 couple of expressions in tc-m68k.c.
4845 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4847 * read.c (cons): If NO_RELOC is defined, use it.
4849 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4851 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4853 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4854 local labels to start with a .) and set REGISTER_PREFIX to %.
4855 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4873 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4874 sections starting from zero, rather than making them consecutive.
4875 This makes subsequent reloc calculations easier, esp if the object
4876 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4877 allocate lcomm in .data rather than in .bss. It seems that some
4878 tools can't cope with a non-zero sized bss before linkage.
4880 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4882 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4901 * Makefile.in (install): if $(tooldir) exists, install as in
4904 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4906 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4907 .word is < -32768 or > 32767. The -J flag causes the error to be
4908 ignored. This is to catch over-sized switches generated by gcc on
4909 systems which don't support the broken .word hack.
4910 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4911 write.c (fixup_segment): check for signed .word overflow if
4912 WARN_SIGNED_OVERFLOW_WORD.
4914 * write.c (fixup_segment): fixed missing parens in expression
4915 checking for byte or word overflow.

4931 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4933 * input-scrub.c (input_scrub_push): call input_file_begin, not
4935 messages.c (as_perror): print ": " between the passed in error and
4936 the strerror, like perror does.
4938 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

4941 From Steve Chamberlain:
4942 Makefile.in: Handle m68*-*-coff*.
4943 read.c, read.h: add mult argument to s_space
4945 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4946 Motorola and MIT syntax; gas can now assemble either type of
4948 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4955 (fixup_segment) set fx_subsy to 0.
4956 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4958 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4961 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4963 * Makefile.in (LIBS): Include opcode library.

4986 little endian byte order (used to use endianness of host).
4988 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4990 * config/tc-m68k.c (init_table): Now const. Always include 68851
4991 data, so that "bc" is available to 68040 cache instructions.
4992 Added "tt0", "tt1", and 68ec030 variants.
4993 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4994 (enum _register): Added TT0, TT1.
4995 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4996 line number correctly in "internal error" messages. Don't print
4997 architecture-mismatch message for operand errors.
4999 From Colin Smith (colin@wrs.com):
5000 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5001 than install_operand.

5022 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5023 has already been formatted (but may still contain %-characters).
5026 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5028 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5029 written with indirection on the last two operands, which can be
5030 either data or address registers. Added a new operand type 'r'
5031 which accepts either register type. Added '(' to notend stuff in
5032 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5050 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5051 their not having symbols associated.
5053 * tc-i960.c (norelax, instrument_branches): Default initializer is
5055 (linkrelax): Delete variable definition.

5079 being used with args swapped, causing occasional lossage when
5080 refilling buffers after an include file.
5082 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5084 * messages.c (as_tsktsk): Use correct ANSI form for stdarg

5090 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5091 selected architecture, print a message saying so and listing what

5138 * expr.c (floating_constant): Separate "=-" to avoid confusing
5139 ancient or broken compilers.
5141 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5142 processor/opcode mismatch, so reword the error message.
5143 (md_assemble): If no CPU has been set (even if FPU/PMMU
5144 characteristics have been), default to 68020. Don't need extra
5145 quotes around error string.

5203 * write.c (write_object_file): various changes to handle data in
5204 the BSS segment in much the same was as stuff in the DATA segment.
5206 * tc-m68k.c (m68kip): Fix typo so that only arch's >=68020 do
5207 pcrel data stuff. (md_estimate_size_before_relax): when relaxing a
5208 68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into
5209 the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put

5214 * expr.c(expr): allow SEG_REGISTER in expressions.
5215 * read.c(pseudo_set): register expressions can be the source of a
5217 * subsegs.c (subseg_new): Now -R forces all changes to SEG_DATA to
5218 goto SEG_TEXT (if a.out)
5219 * write.c (write_object_file): If a.out don't use the old way for
5221 * config/obj-a.out (s_sect): complain if the user tries to use a
5222 subsegment with a value which might interfere with out -R hackery.
5223 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
5224 rather than use ugly if tree. (init_regtable): insert register
5225 names into symbol table.
5227 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5229 * write.c (write_object_file): keep the fix_tail clean, which
5230 fixes a bug in -R where relocations were being lost.
5232 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5234 * configure.in: recognize m680x0 as having sun3 emulation mode for

5257 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5259 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
5260 calc the base of relocs correctly.
5261 * tc-a29k.c (parse_operand): allow expressions to be in any section.
5263 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
5265 * as.c, write.c: use -K rather than -k for the broken word warning
5268 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)

5276 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5278 * write.c (write_object_file): For b.out format, round up section
5279 start addresses to match required alignment.
5281 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5283 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5284 where gcc looks for it.
5286 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5288 * Makefile.in: Changed some lines to be less confusing for some
5291 * input-file.c: Conditionalize on _IOFBF, not VMS.
5293 * read.c, write.c: Change a series of ifdef/elif to
5294 ifdef/else/ifdef etc.

5313 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
5315 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
5316 tc-m68k.h to te-sun3.h.
5318 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
5320 * configure.in: vxworks68 gets te-sun3.h.
5322 * expr.c: remove limitation that local_labels_dollar or
5323 local_labels_fb must be < 10.
5325 * symbols.c: remove local_labels_dollar, replace with a function
5326 interface for a sparse array. All users adjusted.
5328 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
5330 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5332 * doc/Makefile.in: commented out line for building as-all.texinfo.
5335 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
5337 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

5351 * Makefile.in (strerror.o): Add rule so that broken Sun make can
5354 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5356 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5358 * expr.c (operand): if can't work out what sort of operand it is,
5359 then look through FLT_CHARS for a hint.
5361 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5363 * Makefile.in, configure.in: removed traces of namesubdir,
5364 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5365 copyrights to '92, changed some from Cygnus to FSF.
5367 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5368 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5369 copyrights to '92, changed some from Cygnus to FSF.
5371 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5373 * expr.c: If an expression is single comma, then return with
5374 SEG_ABSENT rather than an error - since the sparc front end does
5375 really strange things with things like fbge,a
5377 * as.h: include bfd.h if using many sections
5378 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5379 local labels didn't work.
5380 * listing.c (list_symbol_table): don't core dump when there's no
5382 * write.c, write.h: call fix_new with the right number of args on
5384 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5387 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5389 * app.c: MRI compatibility - allow single quote to start a string.
5390 * as.c: fix typo recently introduced.
5391 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5392 * expr.c: Much rewriting, to accomodate MRI syntax for
5393 expressions. Also easier to read now.
5394 * listing.c: Put back defuns
5395 * read.c: modified to accept MRI syntax, put back listing pseudo
5396 ops so that an assembler built with NO_LISTING ignores list ops
5398 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5399 machine is a SPARC or a 29K.
5400 * config/obj-aout.c: added s_sect pseudo op
5401 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5402 fill in the timestamp.
5403 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5404 anymore, define all the relocs which the tc-<x> bit will use so we
5405 can translate from them to the coff types.
5406 * config/tc-a29k.c: reloc_type isn't ane enum any more
5407 * config/tc-m68k.c: Added NO_RELOC definition.
5409 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5411 * Makefile.in: put header files before C source for TAGS; remove
5412 references to non-existent syscalls.h.
5414 * read.c, write.c subsegs.c: back out the .bss changes.
5416 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5418 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5422 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5424 * symbols.c (local_label_name): symbols now start with ^A.
5426 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5427 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5428 generate these sections. .align: will use NOP_OPCODE or 0
5429 for padding. This is just for being nice to the
5432 * expr.c (operand): changed to generate local label "\001L0"
5433 starting with a ^A so that it is recognized as a local label.
5435 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5437 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5438 i/o opcodes - inb, inw, outb and outw. string manipulation with
5439 att syntax - scmp, slod, smov, ssca, ssto.
5441 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5442 to just after .file .
5444 In obj_crawl_symbol_chain() where it tries to put the external
5445 symbols apart, with the condition:
5446 (!S_IS_DEFINED(symbolP) &&
5447 !S_IS_DEBUG(symbolP) &&
5448 !SF_GET_STATICS(symbolP))
5449 it was moving too many symbols out. So I switch it back to the
5451 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5453 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5454 so that we don't use the F_RELFLG which make the linker complain
5455 that somebody has stripped the relocation info.
5457 Also, the AIX ld program require that the relocation table
5458 is sorted by r_vaddr like the standard ATT assembler does.
5460 [he also changed the sizeof(struct ...)'s into the coff
5461 style FOOSZ macros. I'm not sure this is right, but I can't
5462 remember why. xoxorich.]
5464 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5466 * Makefile.in, configure.in, doc: use the doc. Build it, install
5469 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5471 * read.c: white space and comments only.
5473 * configure.in: use the new atof-ns32.c for ns32k.
5475 * write.c: comment change only.
5477 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5478 aren't yet integrated.
5480 * tc-i860.[hc]: blew off the dust. Something must still be done
5481 about conflicting relocation types.
5483 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5486 * tc-i960.c, tc-sparc.c: white space and comments only.
5488 * tc-a29k.h: delete duplicate macro definition.
5490 * new file atof-ns32k.c copied from hack's last unreleased gas.
5492 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5494 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5497 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5498 ChangeLog's prior to this are sketchy at best. I have logs.
5499 They just aren't ChangeLogs.
