1355 still being worked on. Mark Elf configurations (except sparc and
1356 i386) as developmental. Deleted cases matching some generic names
1357 in favor of more specific names. (E.g., when we get Alpha

1385 Add comments to functions. Delete unused functions, variables,
1386 #defines, etc. Delete unused members within structures. Delete
1387 ldil;ble hacks -- it is believed they were installed to work
1388 around old gas bugs. Avoid using mixed case for local
1389 functions, variables, and structures. Fix formatting problems
1390 not found by GNU-indent. Add FIXME notices for things which
1391 should be worked on the near future. Delete lots of old
1392 useless (1.36 PA-SOM) code.

1467 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1468 ELF, since the ELF object format does not have these type of
1469 relocations. Change the abort into as as_bad and return

2535 * Extensive changes to permit symbols to contain any expression
2536 type and to delay the computation of the expression until the
2537 value is actually needed. This permits setting symbols to values
2538 calculated based on object code size. Expressions were changed to
2539 no longer be in a section, to stop the overloading of segment and
2540 expression type that previously occurred.
2542 * as.c (big_section, pass1_section, diff_section, absent_section):
2544 (expr_section): Added (used for dummy symbols which hold

2628 (previous_section, previous_subsection): New vars.
2629 (obj_elf_section): Save current place in case DWARF code wants us
2630 to pop back to it. Handle unquoted section name as well as quoted
2631 section name. Don't crash on invalid strings.
2632 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

2744 sy_resolved and sy_resolving single bit fields.
2745 * symbols.c (symbol_new): Don't initialize sy_forward field.

3778 * as.h (const, volatile): Put these definitions back, and use
3781 * doc/as.texinfo: First pass at using new texinfo features --
3782 variables, conditional tests. Far from complete.

3810 dependencies are read, not when they are used).
3812 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
3813 a29k .bss section; the mondfe program doesn't like it.

3834 source directory, if that's not the current directory.
3836 * configure.in (per-host): Accept MIPS host with BSD version

3862 avoid some redefinition complaints on some systems.
3863 (const, volatile): Don't need these conditionally defined if we
3864 use CONST and VOLATILE from ansidecl.h.
3865 (seg_name): Use CONST, not const.
3867 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3869 * config/tc-mips.c: Reindented to GNU standards.

3873 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3874 (fixup_segment): Add a29k special case; the linker is not prepared
3875 to see a segment offset here.
3877 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3880 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3882 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3898 bignums, but don't emit error message.
3900 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3902 * Makefile.in (targ-cpu.o): Depend on config.h.
3904 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3906 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3907 dropping a space immediately following an identifier.
3908 * expr.c, write.c: Rewrote assert expressions to not use multiple
3909 lines; I don't think that can be done portably.
3910 * config/tc-mips.c (macro): Use $AT if target register is zero in
3911 load instruction, which it can be for a floating point load.
3913 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3934 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3936 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3937 to be on a single line.

3985 prototypes for all static functions. Moved existing minimal
3986 debugging format support info #ifndef OBJ_ECOFF blocks.

4035 * make-gas.com: Find obstack.obj if it's not in the current
4037 * read.c (s_ignore): Don't declare is_end_of_line. It's
4038 redundant, and triggers a VMS gcc compiler bug.
4040 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4041 current segment as an argument. (Ignored in all cases but VMS.)
4042 All callers and definitions changed.

4339 md_relax_table): Use default zero initialization.
4340 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4341 latter, instead of selecting with preprocessor conditionals.
4343 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4345 * configure.in: recognise all sparclite variants
4347 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4353 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4355 * expr.c (operand): If character other than comma or newline is a
4356 logical end-of-line character, use the newline case.
4357 From Eric Youngdale:
4358 (operand): Set X_add_number field for floating-point numbers.
4359 (operand): Treat zero byte as end-of-operand.
4361 * configure.in (per-target): Look for with_bfd_assembler option.
4362 For now, only accept "no", until the merge is done.
4364 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4365 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4366 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4367 * read.c: Finish conversion to S_* macros in the VMS only
4368 parts of the program. Add "const" modifier to hex_value.
4369 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4371 * expr.c: Add "const" modifier to hex_value.
4372 * symbols.c: Finish conversion to S_* macros in the VMS only
4373 parts of the program. Add "const" modifier to
4374 md_[long,short]_jump_size. Remove declaration of const_flag
4375 (which will be declared in obj-vms.h).
4376 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4377 Fix arguments to VMS_write_object_file.
4378 * config-gas.com: New file. Script for VMS systems to set up the
4379 configuration to build gas for VMS, and create config.status.
4380 * make-gas.com: Redone to work with new scheme.
4381 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4383 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4384 will swap bytes if needed on a big endian system. Use throughout
4386 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4387 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4388 types of malformed stabs. Change parsing algorithm so that we are
4389 more certain of having all of the information that we need on hand.
4390 * obj-vms.c (final_forward_reference): New function, used to help
4391 resolve the data types of as many struct elements as possible
4392 when some part of the struct is not fully defined by the compiler.
4393 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
4395 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4396 as symbols as well in the object file. Look for external functions
4397 that start with "__vt.", and turn them into variables, since the
4398 g++ compiler is incapable of doing this.
4399 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4401 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4402 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4403 have the name of the source file yet.
4404 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4406 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4408 * read.c (s_data): Always use "data_section", since it'll map to
4409 SEG_DATA or SEG_E1 if needed.
4410 (s_lcomm): Likewise with bss_section.
4411 (s_fill): Use memset, not bzero.
4413 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4432 otherwise, use seg_name array.
4433 (seg_name): Declare only if not BFD_ASSEMBLER.
4434 (section_alignment): Declare only if not BFD_ASSEMBLER.
4435 (big_section, reg_section, pass1_section, diff_section,
4436 absent_section, text_section, data_section, bss_section): If
4437 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4438 mapping to segT enum values.
4439 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4440 if these are used or defined, if BFD_ASSEMBLER.
4441 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4442 subseg_new split into two functions.
4443 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4445 * as.h (volatile): Don't define if already defined.
4446 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4448 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4449 declare with format attribute for -Wformat checking.
4451 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4453 * app.c, config/tc-*.c: Don't include read.h, since it is already
4456 * These are based on patches from Minh Tran-le
4457 <mtranle@paris.intellicorp.com>.
4458 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4459 obj_format coffbfd and gas_target i386coff for target.
4460 (i[34]86-*-isc*): New host (uses sysv).
4461 * config/i386aix.mt: Removed (no longer used).
4462 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4464 (LDFLAGS): Added, defined as -shlib.
4465 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4466 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4467 (DOT_LABEL_PREFIX): Define.
4468 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4469 name rather than L0\001.
4470 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4472 * symbols.c, symbols.h (local_bss_counter): Removed.
4473 * write.c (write_object_file): bss no longer uses
4474 local_bss_counter. Pass correct data and bss size to
4475 VMS_write_object_file.

4481 (size_section): Restored sanity check.
4482 (do_relocs_for): Base section address on s_paddr rather than
4483 computing it. Adjust a29k R_IHIHALF special case to account for
4484 section paddr (used to require paddr to be zero). If there are no
4485 reclos, set s_relptr to 0. Set relocation size in object_headers.
4486 (fill_section): Always set s_vaddr here, removing
4487 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4488 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4489 Set STYP_INFO for .comment.
4490 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4491 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4493 H_{SET,GET}_* macros.
4494 (do_linenos_for): Set lineno size in object_headers.
4495 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4496 set s_vaddr here. If string_byte_count remains 4, set it back to
4497 0, and only write strings out if there are some. Call
4498 fill_section before do_relocs_for and do_linenos_for.
4499 (obj_coff_section): Handle optional quoted second argument giving
4500 section characteristics.
4501 (obj_coff_bss): Added to handle .bss.
4502 (obj_coff_ident): Added to handle .ident (puts string in .comment
4504 (obj_coff_lcomm): Put common symbols in .bss, not .data.
4505 (fixup_mdeps): Change to segment. Call frag_wane after
4507 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4508 adjustment (already happened only for common symbols, but this is
4510 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
4511 * config/tc-i386.c (s_bss): Don't use if I386COFF.

4522 (do_scrub_next_char): For \", return " not '.
4523 (symbol_chars): Now const.
4525 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4526 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4528 * config/obj-coff.h: Don't use #elif.
4530 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4531 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4533 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4535 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4555 SEG_BSS, fill with NOP_OPCODE.
4556 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4557 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4558 using ZERO_BASED_SEGMENTS.
4559 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4560 never set segment address for SEG_E2 (.bss) and don't write out
4561 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4562 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4563 definitions, and don't merge tags with non-tags. Check for .bf
4564 rather than just checking whether the second character is b and
4565 the third character is f.
4566 (obj_coff_val): gcc can generate values which we don't handle
4567 correctly; discard information for now, since it only affects the
4568 debugging information.
4569 (tag_find_or_name): Don't insert tags in the symbol table.
4570 (yank_symbols): Don't merge labels.
4571 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4574 (obj_coff_section): Accept and ignore a trailing quoted string, as
4575 used in AT&T i386 syntax.

4749 consistently const, and always initialized them. Included read.h.
4751 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4753 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4754 constant will not fit in an immediate field.
4755 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4757 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

4774 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
4775 so widening works consistently.
4777 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
4779 * version.c: Put conditional "const" before version_string, not

4790 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4792 * Support for i386-sysv.
4793 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
4794 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4795 be used to set them all to zero as was done before.

4797 (fill_section): Don't set STYP_NOLOAD for .bss section.
4798 (fixup_segment): 386 uses strange common symbol format.

4835 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4836 #elif, since it is not supported by old compilers.
4837 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4838 couple of expressions in tc-m68k.c.
4840 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4842 * read.c (cons): If NO_RELOC is defined, use it.
4844 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4846 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4848 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4849 local labels to start with a .) and set REGISTER_PREFIX to %.

4868 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4869 sections starting from zero, rather than making them consecutive.
4870 This makes subsequent reloc calculations easier, esp if the object
4871 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4872 allocate lcomm in .data rather than in .bss. It seems that some
4873 tools can't cope with a non-zero sized bss before linkage.
4875 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4877 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4892 Change LIBDEPS dependence to LIBS.
4894 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4896 * Makefile.in (install): if $(tooldir) exists, install as in
4899 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4901 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4902 .word is < -32768 or > 32767. The -J flag causes the error to be
4903 ignored. This is to catch over-sized switches generated by gcc on
4904 systems which don't support the broken .word hack.
4905 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4906 write.c (fixup_segment): check for signed .word overflow if
4907 WARN_SIGNED_OVERFLOW_WORD.
4909 * write.c (fixup_segment): fixed missing parens in expression

4924 * tc-i386.h : new coff defines
4926 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4928 * input-scrub.c (input_scrub_push): call input_file_begin, not
4930 messages.c (as_perror): print ": " between the passed in error and
4931 the strerror, like perror does.
4933 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

4936 From Steve Chamberlain:
4937 Makefile.in: Handle m68*-*-coff*.
4938 read.c, read.h: add mult argument to s_space
4940 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4941 Motorola and MIT syntax; gas can now assemble either type of
4943 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4950 (fixup_segment) set fx_subsy to 0.
4951 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4953 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4956 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4958 * Makefile.in (LIBS): Include opcode library.

4983 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4985 * config/tc-m68k.c (init_table): Now const. Always include 68851
4986 data, so that "bc" is available to 68040 cache instructions.
4987 Added "tt0", "tt1", and 68ec030 variants.
4988 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4989 (enum _register): Added TT0, TT1.
4990 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4991 line number correctly in "internal error" messages. Don't print
4992 architecture-mismatch message for operand errors.
4994 From Colin Smith (colin@wrs.com):
4995 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

5017 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5018 has already been formatted (but may still contain %-characters).
5021 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5023 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5024 written with indirection on the last two operands, which can be
5025 either data or address registers. Added a new operand type 'r'
5026 which accepts either register type. Added '(' to notend stuff in
5027 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5045 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5046 their not having symbols associated.
5048 * tc-i960.c (norelax, instrument_branches): Default initializer is

5074 being used with args swapped, causing occasional lossage when
5075 refilling buffers after an include file.

5085 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5086 selected architecture, print a message saying so and listing what

5133 * expr.c (floating_constant): Separate "=-" to avoid confusing
5134 ancient or broken compilers.
5136 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5137 processor/opcode mismatch, so reword the error message.
5138 (md_assemble): If no CPU has been set (even if FPU/PMMU
5139 characteristics have been), default to 68020. Don't need extra
5140 quotes around error string.

5209 * expr.c(expr): allow SEG_REGISTER in expressions.
5210 * read.c(pseudo_set): register expressions can be the source of a
5212 * subsegs.c (subseg_new): Now -R forces all changes to SEG_DATA to
5213 goto SEG_TEXT (if a.out)
5214 * write.c (write_object_file): If a.out don't use the old way for
5216 * config/obj-a.out (s_sect): complain if the user tries to use a
5217 subsegment with a value which might interfere with out -R hackery.
5218 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
5219 rather than use ugly if tree. (init_regtable): insert register
5220 names into symbol table.
5222 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5224 * write.c (write_object_file): keep the fix_tail clean, which
5225 fixes a bug in -R where relocations were being lost.
5227 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5229 * configure.in: recognize m680x0 as having sun3 emulation mode for
5230 vxworks environment.
5232 Sun May 31 05:33:00 1992 david d `zoo' zuhn (zoo@cygnus.com)

5252 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5254 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
5255 calc the base of relocs correctly.
5256 * tc-a29k.c (parse_operand): allow expressions to be in any section.
5258 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
5260 * as.c, write.c: use -K rather than -k for the broken word warning
5263 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)

5271 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5273 * write.c (write_object_file): For b.out format, round up section
5274 start addresses to match required alignment.
5276 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5278 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5279 where gcc looks for it.
5281 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5283 * Makefile.in: Changed some lines to be less confusing for some
5286 * input-file.c: Conditionalize on _IOFBF, not VMS.
5288 * read.c, write.c: Change a series of ifdef/elif to
5289 ifdef/else/ifdef etc.
5291 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)

5303 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5305 * flonum-const.c: renamed flonum-konst.c to stop dos name
5308 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
5310 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
5311 tc-m68k.h to te-sun3.h.
5313 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
5315 * configure.in: vxworks68 gets te-sun3.h.
5317 * expr.c: remove limitation that local_labels_dollar or
5318 local_labels_fb must be < 10.
5320 * symbols.c: remove local_labels_dollar, replace with a function
5321 interface for a sparse array. All users adjusted.
5323 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
5325 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5327 * doc/Makefile.in: commented out line for building as-all.texinfo.
5330 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
5332 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

5346 * Makefile.in (strerror.o): Add rule so that broken Sun make can
5349 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5351 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5353 * expr.c (operand): if can't work out what sort of operand it is,
5354 then look through FLT_CHARS for a hint.
5356 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5358 * Makefile.in, configure.in: removed traces of namesubdir,
5359 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5360 copyrights to '92, changed some from Cygnus to FSF.
5362 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5363 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5364 copyrights to '92, changed some from Cygnus to FSF.
5366 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5368 * expr.c: If an expression is single comma, then return with
5369 SEG_ABSENT rather than an error - since the sparc front end does
5370 really strange things with things like fbge,a
5372 * as.h: include bfd.h if using many sections
5373 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5374 local labels didn't work.
5375 * listing.c (list_symbol_table): don't core dump when there's no
5377 * write.c, write.h: call fix_new with the right number of args on
5379 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5382 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5384 * app.c: MRI compatibility - allow single quote to start a string.
5385 * as.c: fix typo recently introduced.
5386 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5387 * expr.c: Much rewriting, to accomodate MRI syntax for
5388 expressions. Also easier to read now.
5389 * listing.c: Put back defuns
5390 * read.c: modified to accept MRI syntax, put back listing pseudo
5391 ops so that an assembler built with NO_LISTING ignores list ops
5393 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5394 machine is a SPARC or a 29K.
5395 * config/obj-aout.c: added s_sect pseudo op
5396 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5397 fill in the timestamp.
5398 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5399 anymore, define all the relocs which the tc-<x> bit will use so we
5400 can translate from them to the coff types.
5401 * config/tc-a29k.c: reloc_type isn't ane enum any more
5402 * config/tc-m68k.c: Added NO_RELOC definition.
5404 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5406 * Makefile.in: put header files before C source for TAGS; remove
5407 references to non-existent syscalls.h.
5409 * read.c, write.c subsegs.c: back out the .bss changes.
5411 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5413 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5417 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5419 * symbols.c (local_label_name): symbols now start with ^A.
5421 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5422 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5423 generate these sections. .align: will use NOP_OPCODE or 0
5424 for padding. This is just for being nice to the
5427 * expr.c (operand): changed to generate local label "\001L0"
5428 starting with a ^A so that it is recognized as a local label.
5430 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5432 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5433 i/o opcodes - inb, inw, outb and outw. string manipulation with
5434 att syntax - scmp, slod, smov, ssca, ssto.
5436 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5437 to just after .file .
5439 In obj_crawl_symbol_chain() where it tries to put the external
5440 symbols apart, with the condition:
5441 (!S_IS_DEFINED(symbolP) &&
5442 !S_IS_DEBUG(symbolP) &&
5443 !SF_GET_STATICS(symbolP))
5444 it was moving too many symbols out. So I switch it back to the
5446 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5448 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5449 so that we don't use the F_RELFLG which make the linker complain
5450 that somebody has stripped the relocation info.
5452 Also, the AIX ld program require that the relocation table
5453 is sorted by r_vaddr like the standard ATT assembler does.
5455 [he also changed the sizeof(struct ...)'s into the coff
5456 style FOOSZ macros. I'm not sure this is right, but I can't
5457 remember why. xoxorich.]
5459 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5461 * Makefile.in, configure.in, doc: use the doc. Build it, install
5464 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5466 * read.c: white space and comments only.
5468 * configure.in: use the new atof-ns32.c for ns32k.
5470 * write.c: comment change only.
5472 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5473 aren't yet integrated.
5475 * tc-i860.[hc]: blew off the dust. Something must still be done
5476 about conflicting relocation types.
5478 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5481 * tc-i960.c, tc-sparc.c: white space and comments only.
5483 * tc-a29k.h: delete duplicate macro definition.
5485 * new file atof-ns32k.c copied from hack's last unreleased gas.
5487 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5489 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5492 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5493 ChangeLog's prior to this are sketchy at best. I have logs.
5494 They just aren't ChangeLogs.
