1341 still being worked on. Mark Elf configurations (except sparc and
1342 i386) as developmental. Deleted cases matching some generic names
1343 in favor of more specific names. (E.g., when we get Alpha

1361 for functions only used within tc-hppa.c, likewise for structures,
1362 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1363 conditional code in a few small places.
1365 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group

1371 Add comments to functions. Delete unused functions, variables,
1372 #defines, etc. Delete unused members within structures. Delete
1373 ldil;ble hacks -- it is believed they were installed to work
1374 around old gas bugs. Avoid using mixed case for local
1375 functions, variables, and structures. Fix formatting problems
1376 not found by GNU-indent. Add FIXME notices for things which
1377 should be worked on the near future. Delete lots of old
1378 useless (1.36 PA-SOM) code.

2521 * Extensive changes to permit symbols to contain any expression
2522 type and to delay the computation of the expression until the
2523 value is actually needed. This permits setting symbols to values
2524 calculated based on object code size. Expressions were changed to
2525 no longer be in a section, to stop the overloading of segment and
2526 expression type that previously occurred.
2528 * as.c (big_section, pass1_section, diff_section, absent_section):
2530 (expr_section): Added (used for dummy symbols which hold

2614 (previous_section, previous_subsection): New vars.
2615 (obj_elf_section): Save current place in case DWARF code wants us
2616 to pop back to it. Handle unquoted section name as well as quoted
2617 section name. Don't crash on invalid strings.
2618 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

2730 sy_resolved and sy_resolving single bit fields.
2731 * symbols.c (symbol_new): Don't initialize sy_forward field.

3767 * doc/as.texinfo: First pass at using new texinfo features --
3768 variables, conditional tests. Far from complete.

3848 avoid some redefinition complaints on some systems.
3849 (const, volatile): Don't need these conditionally defined if we
3850 use CONST and VOLATILE from ansidecl.h.
3851 (seg_name): Use CONST, not const.
3853 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3855 * config/tc-mips.c: Reindented to GNU standards.

3866 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3868 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3884 bignums, but don't emit error message.
3886 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3888 * Makefile.in (targ-cpu.o): Depend on config.h.
3890 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3892 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3893 dropping a space immediately following an identifier.
3894 * expr.c, write.c: Rewrote assert expressions to not use multiple
3895 lines; I don't think that can be done portably.
3896 * config/tc-mips.c (macro): Use $AT if target register is zero in
3897 load instruction, which it can be for a floating point load.
3899 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3920 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3922 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3923 to be on a single line.

3971 prototypes for all static functions. Moved existing minimal
3972 debugging format support info #ifndef OBJ_ECOFF blocks.

4021 * make-gas.com: Find obstack.obj if it's not in the current
4023 * read.c (s_ignore): Don't declare is_end_of_line. It's
4024 redundant, and triggers a VMS gcc compiler bug.
4026 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4027 current segment as an argument. (Ignored in all cases but VMS.)
4028 All callers and definitions changed.

4324 * config/tc-sparc.c (architecture_requested, warn_on_bump,
4325 md_relax_table): Use default zero initialization.
4326 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4327 latter, instead of selecting with preprocessor conditionals.
4329 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4331 * configure.in: recognise all sparclite variants
4333 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4336 accidentally changed to use subseg_change where it should have
4339 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4341 * expr.c (operand): If character other than comma or newline is a
4342 logical end-of-line character, use the newline case.
4343 From Eric Youngdale:
4344 (operand): Set X_add_number field for floating-point numbers.
4345 (operand): Treat zero byte as end-of-operand.
4347 * configure.in (per-target): Look for with_bfd_assembler option.
4348 For now, only accept "no", until the merge is done.
4350 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4351 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4352 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4353 * read.c: Finish conversion to S_* macros in the VMS only
4354 parts of the program. Add "const" modifier to hex_value.
4355 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4357 * expr.c: Add "const" modifier to hex_value.
4358 * symbols.c: Finish conversion to S_* macros in the VMS only
4359 parts of the program. Add "const" modifier to
4360 md_[long,short]_jump_size. Remove declaration of const_flag
4361 (which will be declared in obj-vms.h).
4362 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4363 Fix arguments to VMS_write_object_file.
4364 * config-gas.com: New file. Script for VMS systems to set up the
4365 configuration to build gas for VMS, and create config.status.
4366 * make-gas.com: Redone to work with new scheme.
4367 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4369 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4370 will swap bytes if needed on a big endian system. Use throughout
4372 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4373 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4374 types of malformed stabs. Change parsing algorithm so that we are
4375 more certain of having all of the information that we need on hand.
4376 * obj-vms.c (final_forward_reference): New function, used to help
4377 resolve the data types of as many struct elements as possible
4378 when some part of the struct is not fully defined by the compiler.
4379 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
4381 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4382 as symbols as well in the object file. Look for external functions
4383 that start with "__vt.", and turn them into variables, since the
4384 g++ compiler is incapable of doing this.
4385 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4387 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4388 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4389 have the name of the source file yet.
4390 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4392 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4394 * read.c (s_data): Always use "data_section", since it'll map to
4395 SEG_DATA or SEG_E1 if needed.
4396 (s_lcomm): Likewise with bss_section.
4397 (s_fill): Use memset, not bzero.
4399 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4420 (section_alignment): Declare only if not BFD_ASSEMBLER.
4421 (big_section, reg_section, pass1_section, diff_section,
4422 absent_section, text_section, data_section, bss_section): If
4423 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4424 mapping to segT enum values.
4425 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4426 if these are used or defined, if BFD_ASSEMBLER.
4427 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4428 subseg_new split into two functions.
4429 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4431 * as.h (volatile): Don't define if already defined.
4432 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4434 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4435 declare with format attribute for -Wformat checking.
4437 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4439 * app.c, config/tc-*.c: Don't include read.h, since it is already
4442 * These are based on patches from Minh Tran-le
4443 <mtranle@paris.intellicorp.com>.
4444 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4445 obj_format coffbfd and gas_target i386coff for target.
4446 (i[34]86-*-isc*): New host (uses sysv).
4447 * config/i386aix.mt: Removed (no longer used).
4448 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4450 (LDFLAGS): Added, defined as -shlib.
4451 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4452 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4453 (DOT_LABEL_PREFIX): Define.
4454 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4455 name rather than L0\001.
4456 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4458 * symbols.c, symbols.h (local_bss_counter): Removed.
4459 * write.c (write_object_file): bss no longer uses
4460 local_bss_counter. Pass correct data and bss size to
4461 VMS_write_object_file.

4467 (size_section): Restored sanity check.
4468 (do_relocs_for): Base section address on s_paddr rather than
4469 computing it. Adjust a29k R_IHIHALF special case to account for
4470 section paddr (used to require paddr to be zero). If there are no
4471 reclos, set s_relptr to 0. Set relocation size in object_headers.
4472 (fill_section): Always set s_vaddr here, removing
4473 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4474 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4475 Set STYP_INFO for .comment.
4476 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4477 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4479 H_{SET,GET}_* macros.
4480 (do_linenos_for): Set lineno size in object_headers.
4481 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4482 set s_vaddr here. If string_byte_count remains 4, set it back to
4483 0, and only write strings out if there are some. Call
4484 fill_section before do_relocs_for and do_linenos_for.
4485 (obj_coff_section): Handle optional quoted second argument giving
4486 section characteristics.
4487 (obj_coff_bss): Added to handle .bss.
4488 (obj_coff_ident): Added to handle .ident (puts string in .comment

4491 (fixup_mdeps): Change to segment. Call frag_wane after
4493 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4494 adjustment (already happened only for common symbols, but this is
4496 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
4497 * config/tc-i386.c (s_bss): Don't use if I386COFF.

4508 (do_scrub_next_char): For \", return " not '.
4509 (symbol_chars): Now const.
4511 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4512 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4514 * config/obj-coff.h: Don't use #elif.
4516 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4517 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4519 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

4543 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4544 using ZERO_BASED_SEGMENTS.
4545 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4546 never set segment address for SEG_E2 (.bss) and don't write out
4547 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4548 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4549 definitions, and don't merge tags with non-tags. Check for .bf
4550 rather than just checking whether the second character is b and
4551 the third character is f.
4552 (obj_coff_val): gcc can generate values which we don't handle
4553 correctly; discard information for now, since it only affects the
4554 debugging information.
4555 (tag_find_or_name): Don't insert tags in the symbol table.
4556 (yank_symbols): Don't merge labels.
4557 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4735 consistently const, and always initialized them. Included read.h.
4737 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4739 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4740 constant will not fit in an immediate field.
4741 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4743 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

4763 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
4765 * version.c: Put conditional "const" before version_string, not

4768 * app.c (do_scrub_next_char): Need double-\ before `000' to show
4769 printed rep of null character.
4771 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
4773 * obj-coffbfd.c (write_object_file): check return value of
4776 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4778 * Support for i386-sysv.
4779 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
4780 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4781 be used to set them all to zero as was done before.

4783 (fill_section): Don't set STYP_NOLOAD for .bss section.
4784 (fixup_segment): 386 uses strange common symbol format.

4817 * tc-z8k.c: lots of bug fixes
4819 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4821 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4822 #elif, since it is not supported by old compilers.
4823 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4824 couple of expressions in tc-m68k.c.
4826 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4828 * read.c (cons): If NO_RELOC is defined, use it.
4830 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4832 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4834 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4835 local labels to start with a .) and set REGISTER_PREFIX to %.
4836 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4854 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4855 sections starting from zero, rather than making them consecutive.
4856 This makes subsequent reloc calculations easier, esp if the object
4857 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4858 allocate lcomm in .data rather than in .bss. It seems that some
4859 tools can't cope with a non-zero sized bss before linkage.
4861 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4863 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4882 * Makefile.in (install): if $(tooldir) exists, install as in
4885 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4887 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4888 .word is < -32768 or > 32767. The -J flag causes the error to be
4889 ignored. This is to catch over-sized switches generated by gcc on
4890 systems which don't support the broken .word hack.
4891 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4892 write.c (fixup_segment): check for signed .word overflow if
4893 WARN_SIGNED_OVERFLOW_WORD.

4912 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4914 * input-scrub.c (input_scrub_push): call input_file_begin, not
4916 messages.c (as_perror): print ": " between the passed in error and
4917 the strerror, like perror does.

4922 From Steve Chamberlain:
4923 Makefile.in: Handle m68*-*-coff*.
4924 read.c, read.h: add mult argument to s_space
4926 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4927 Motorola and MIT syntax; gas can now assemble either type of

4937 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4939 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4942 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4944 * Makefile.in (LIBS): Include opcode library.

4969 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4971 * config/tc-m68k.c (init_table): Now const. Always include 68851
4972 data, so that "bc" is available to 68040 cache instructions.
4973 Added "tt0", "tt1", and 68ec030 variants.
4974 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4975 (enum _register): Added TT0, TT1.
4976 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4977 line number correctly in "internal error" messages. Don't print
4978 architecture-mismatch message for operand errors.
4980 From Colin Smith (colin@wrs.com):
4981 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4982 than install_operand.

5003 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5004 has already been formatted (but may still contain %-characters).
5007 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5009 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5010 written with indirection on the last two operands, which can be
5011 either data or address registers. Added a new operand type 'r'
5012 which accepts either register type. Added '(' to notend stuff in
5013 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5032 their not having symbols associated.
5034 * tc-i960.c (norelax, instrument_branches): Default initializer is

5119 * expr.c (floating_constant): Separate "=-" to avoid confusing
5120 ancient or broken compilers.
5122 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5123 processor/opcode mismatch, so reword the error message.
5124 (md_assemble): If no CPU has been set (even if FPU/PMMU
5125 characteristics have been), default to 68020. Don't need extra
5126 quotes around error string.

5205 rather than use ugly if tree. (init_regtable): insert register
5206 names into symbol table.
5208 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5210 * write.c (write_object_file): keep the fix_tail clean, which
5211 fixes a bug in -R where relocations were being lost.
5213 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5215 * configure.in: recognize m680x0 as having sun3 emulation mode for
5216 vxworks environment.
5218 Sun May 31 05:33:00 1992 david d `zoo' zuhn (zoo@cygnus.com)

5238 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5240 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
5241 calc the base of relocs correctly.
5242 * tc-a29k.c (parse_operand): allow expressions to be in any section.
5244 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
5246 * as.c, write.c: use -K rather than -k for the broken word warning
5249 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)

5257 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5259 * write.c (write_object_file): For b.out format, round up section
5260 start addresses to match required alignment.
5262 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5264 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5265 where gcc looks for it.
5267 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5269 * Makefile.in: Changed some lines to be less confusing for some
5272 * input-file.c: Conditionalize on _IOFBF, not VMS.
5274 * read.c, write.c: Change a series of ifdef/elif to
5275 ifdef/else/ifdef etc.

5289 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5291 * flonum-const.c: renamed flonum-konst.c to stop dos name
5294 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
5296 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
5297 tc-m68k.h to te-sun3.h.
5299 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
5301 * configure.in: vxworks68 gets te-sun3.h.
5303 * expr.c: remove limitation that local_labels_dollar or
5304 local_labels_fb must be < 10.
5306 * symbols.c: remove local_labels_dollar, replace with a function
5307 interface for a sparse array. All users adjusted.
5309 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
5311 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5313 * doc/Makefile.in: commented out line for building as-all.texinfo.
5316 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
5318 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

5330 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
5332 * Makefile.in (strerror.o): Add rule so that broken Sun make can
5335 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5337 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5339 * expr.c (operand): if can't work out what sort of operand it is,
5340 then look through FLT_CHARS for a hint.
5342 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5344 * Makefile.in, configure.in: removed traces of namesubdir,
5345 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5346 copyrights to '92, changed some from Cygnus to FSF.
5348 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5349 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5350 copyrights to '92, changed some from Cygnus to FSF.
5352 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5354 * expr.c: If an expression is single comma, then return with
5355 SEG_ABSENT rather than an error - since the sparc front end does
5356 really strange things with things like fbge,a
5358 * as.h: include bfd.h if using many sections
5359 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5360 local labels didn't work.
5361 * listing.c (list_symbol_table): don't core dump when there's no
5363 * write.c, write.h: call fix_new with the right number of args on
5365 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5368 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5370 * app.c: MRI compatibility - allow single quote to start a string.
5371 * as.c: fix typo recently introduced.
5372 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5373 * expr.c: Much rewriting, to accomodate MRI syntax for
5374 expressions. Also easier to read now.
5375 * listing.c: Put back defuns
5376 * read.c: modified to accept MRI syntax, put back listing pseudo
5377 ops so that an assembler built with NO_LISTING ignores list ops
5379 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5380 machine is a SPARC or a 29K.
5381 * config/obj-aout.c: added s_sect pseudo op
5382 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5383 fill in the timestamp.
5384 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5385 anymore, define all the relocs which the tc-<x> bit will use so we
5386 can translate from them to the coff types.
5387 * config/tc-a29k.c: reloc_type isn't ane enum any more
5388 * config/tc-m68k.c: Added NO_RELOC definition.
5390 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5392 * Makefile.in: put header files before C source for TAGS; remove
5393 references to non-existent syscalls.h.
5395 * read.c, write.c subsegs.c: back out the .bss changes.
5397 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5399 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5403 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5405 * symbols.c (local_label_name): symbols now start with ^A.
5407 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5408 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5409 generate these sections. .align: will use NOP_OPCODE or 0
5410 for padding. This is just for being nice to the
5413 * expr.c (operand): changed to generate local label "\001L0"
5414 starting with a ^A so that it is recognized as a local label.
5416 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5418 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5419 i/o opcodes - inb, inw, outb and outw. string manipulation with
5420 att syntax - scmp, slod, smov, ssca, ssto.
5422 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5423 to just after .file .
5425 In obj_crawl_symbol_chain() where it tries to put the external
5426 symbols apart, with the condition:
5427 (!S_IS_DEFINED(symbolP) &&
5428 !S_IS_DEBUG(symbolP) &&
5429 !SF_GET_STATICS(symbolP))
5430 it was moving too many symbols out. So I switch it back to the
5432 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5434 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5435 so that we don't use the F_RELFLG which make the linker complain
5436 that somebody has stripped the relocation info.
5438 Also, the AIX ld program require that the relocation table
5439 is sorted by r_vaddr like the standard ATT assembler does.
5441 [he also changed the sizeof(struct ...)'s into the coff
5442 style FOOSZ macros. I'm not sure this is right, but I can't
5443 remember why. xoxorich.]
5445 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5447 * Makefile.in, configure.in, doc: use the doc. Build it, install
5450 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5452 * read.c: white space and comments only.
5454 * configure.in: use the new atof-ns32.c for ns32k.
5456 * write.c: comment change only.
5458 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5459 aren't yet integrated.
5461 * tc-i860.[hc]: blew off the dust. Something must still be done
5462 about conflicting relocation types.
5464 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5467 * tc-i960.c, tc-sparc.c: white space and comments only.
5469 * tc-a29k.h: delete duplicate macro definition.
5471 * new file atof-ns32k.c copied from hack's last unreleased gas.
5473 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5475 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5478 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5479 ChangeLog's prior to this are sketchy at best. I have logs.
5480 They just aren't ChangeLogs.
