1009 OPTIONAL_REGISTER_PREFIX if either is already defined.
1011 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
1013 * configure.in: Set bfd_gas for all sparc targets. Added facility
1014 for keeping or rejecting configurations still under development;
1015 default is to assume production environment, and reject configs
1016 still being worked on. Mark Elf configurations (except sparc and
1017 i386) as developmental. Deleted cases matching some generic names
1018 in favor of more specific names. (E.g., when we get Alpha

1035 through inclusion of tc-hppa.h. Delete all forward declarations
1036 for functions only used within tc-hppa.c, likewise for structures,
1037 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1038 conditional code in a few small places.
1040 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1041 structures, global variables, forward declarations together.
1042 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
1043 conditional code -- try to group conditional code together
1044 into a few places. Make all functions and variables which
1045 are only used within tc-hppa.c static. PARAMize all functions.
1046 Add comments to functions. Delete unused functions, variables,
1047 #defines, etc. Delete unused members within structures. Delete
1048 ldil;ble hacks -- it is believed they were installed to work
1049 around old gas bugs. Avoid using mixed case for local
1050 functions, variables, and structures. Fix formatting problems
1051 not found by GNU-indent. Add FIXME notices for things which
1052 should be worked on the near future. Delete lots of old
1053 useless (1.36 PA-SOM) code.

1065 which do not involve function symbols.
1067 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
1068 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
1070 * config/tc-hppa.c: Likewise.
1072 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1073 of elf32_symbol_type.
1074 (pa_export_args): Likewise.
1075 (elf_hppa_final_processing): Likewise.
1076 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

1082 a multiple of the section alignment rather than always a
1085 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

1126 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1128 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1129 ELF, since the ELF object format does not have these type of
1130 relocations. Change the abort into as as_bad and return
1131 BFD_RELOC_NONE to silence compiler warnings.
1132 (md_assemble): Keep track of the instruction size. Allow white
1133 space between the $ and the constant for compatibility with older
1134 gases and other assemblers.

3474 a29k .bss section; the mondfe program doesn't like it.

3495 source directory, if that's not the current directory.
3497 * configure.in (per-host): Accept MIPS host with BSD version

3523 avoid some redefinition complaints on some systems.
3524 (const, volatile): Don't need these conditionally defined if we
3525 use CONST and VOLATILE from ansidecl.h.
3526 (seg_name): Use CONST, not const.
3528 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3530 * config/tc-mips.c: Reindented to GNU standards.

3534 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3535 (fixup_segment): Add a29k special case; the linker is not prepared
3536 to see a segment offset here.
3538 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3541 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3543 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3544 srcdir, might be in objdir.

3563 * Makefile.in (targ-cpu.o): Depend on config.h.
3565 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3567 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3568 dropping a space immediately following an identifier.
3569 * expr.c, write.c: Rewrote assert expressions to not use multiple
3570 lines; I don't think that can be done portably.
3571 * config/tc-mips.c (macro): Use $AT if target register is zero in
3572 load instruction, which it can be for a floating point load.
3574 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3595 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3597 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3598 to be on a single line.
3600 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3646 prototypes for all static functions. Moved existing minimal
3647 debugging format support info #ifndef OBJ_ECOFF blocks.

3696 * make-gas.com: Find obstack.obj if it's not in the current
3698 * read.c (s_ignore): Don't declare is_end_of_line. It's
3699 redundant, and triggers a VMS gcc compiler bug.
3701 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3702 current segment as an argument. (Ignored in all cases but VMS.)
3703 All callers and definitions changed.

4000 md_relax_table): Use default zero initialization.
4001 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4002 latter, instead of selecting with preprocessor conditionals.
4004 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4006 * configure.in: recognise all sparclite variants

4016 * expr.c (operand): If character other than comma or newline is a
4017 logical end-of-line character, use the newline case.
4018 From Eric Youngdale:
4019 (operand): Set X_add_number field for floating-point numbers.
4020 (operand): Treat zero byte as end-of-operand.
4022 * configure.in (per-target): Look for with_bfd_assembler option.
4023 For now, only accept "no", until the merge is done.
4025 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4026 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4032 * expr.c: Add "const" modifier to hex_value.
4033 * symbols.c: Finish conversion to S_* macros in the VMS only
4034 parts of the program. Add "const" modifier to
4035 md_[long,short]_jump_size. Remove declaration of const_flag
4036 (which will be declared in obj-vms.h).
4037 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4038 Fix arguments to VMS_write_object_file.
4039 * config-gas.com: New file. Script for VMS systems to set up the
4040 configuration to build gas for VMS, and create config.status.
4041 * make-gas.com: Redone to work with new scheme.
4042 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

4047 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4048 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4049 types of malformed stabs. Change parsing algorithm so that we are
4050 more certain of having all of the information that we need on hand.
4051 * obj-vms.c (final_forward_reference): New function, used to help
4052 resolve the data types of as many struct elements as possible
4053 when some part of the struct is not fully defined by the compiler.

4056 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4057 as symbols as well in the object file. Look for external functions

4059 g++ compiler is incapable of doing this.
4060 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4062 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4063 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4064 have the name of the source file yet.
4065 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4067 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4069 * read.c (s_data): Always use "data_section", since it'll map to
4070 SEG_DATA or SEG_E1 if needed.
4071 (s_lcomm): Likewise with bss_section.
4072 (s_fill): Use memset, not bzero.
4074 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4096 (big_section, reg_section, pass1_section, diff_section,
4097 absent_section, text_section, data_section, bss_section): If
4098 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4099 mapping to segT enum values.
4100 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4101 if these are used or defined, if BFD_ASSEMBLER.
4102 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4103 subseg_new split into two functions.
4104 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4106 * as.h (volatile): Don't define if already defined.
4107 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4109 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4110 declare with format attribute for -Wformat checking.
4112 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4114 * app.c, config/tc-*.c: Don't include read.h, since it is already
4117 * These are based on patches from Minh Tran-le
4118 <mtranle@paris.intellicorp.com>.
4119 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4120 obj_format coffbfd and gas_target i386coff for target.
4121 (i[34]86-*-isc*): New host (uses sysv).
4122 * config/i386aix.mt: Removed (no longer used).
4123 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4125 (LDFLAGS): Added, defined as -shlib.
4126 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4127 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4128 (DOT_LABEL_PREFIX): Define.
4129 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4130 name rather than L0\001.
4131 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4133 * symbols.c, symbols.h (local_bss_counter): Removed.

4142 (size_section): Restored sanity check.
4143 (do_relocs_for): Base section address on s_paddr rather than
4144 computing it. Adjust a29k R_IHIHALF special case to account for
4145 section paddr (used to require paddr to be zero). If there are no
4146 reclos, set s_relptr to 0. Set relocation size in object_headers.
4147 (fill_section): Always set s_vaddr here, removing
4148 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4149 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4150 Set STYP_INFO for .comment.
4151 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4152 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4154 H_{SET,GET}_* macros.
4155 (do_linenos_for): Set lineno size in object_headers.
4156 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4157 set s_vaddr here. If string_byte_count remains 4, set it back to
4158 0, and only write strings out if there are some. Call
4159 fill_section before do_relocs_for and do_linenos_for.
4160 (obj_coff_section): Handle optional quoted second argument giving
4161 section characteristics.
4162 (obj_coff_bss): Added to handle .bss.
4163 (obj_coff_ident): Added to handle .ident (puts string in .comment

4183 (do_scrub_next_char): For \", return " not '.
4184 (symbol_chars): Now const.
4186 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4187 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4189 * config/obj-coff.h: Don't use #elif.
4191 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4192 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4194 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4196 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4218 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4219 using ZERO_BASED_SEGMENTS.
4220 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4221 never set segment address for SEG_E2 (.bss) and don't write out
4222 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4223 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4224 definitions, and don't merge tags with non-tags. Check for .bf
4225 rather than just checking whether the second character is b and
4226 the third character is f.

4378 could be doing emulation.
4380 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4383 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4412 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4414 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4415 constant will not fit in an immediate field.
4416 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4451 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4453 * Support for i386-sysv.
4454 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4492 * tc-z8k.c: lots of bug fixes
4494 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4496 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4497 #elif, since it is not supported by old compilers.
4498 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4499 couple of expressions in tc-m68k.c.
4501 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4503 * read.c (cons): If NO_RELOC is defined, use it.
4505 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4507 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4509 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4510 local labels to start with a .) and set REGISTER_PREFIX to %.
4511 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4513 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4527 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4529 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4530 sections starting from zero, rather than making them consecutive.
4531 This makes subsequent reloc calculations easier, esp if the object
4532 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4533 allocate lcomm in .data rather than in .bss. It seems that some
4534 tools can't cope with a non-zero sized bss before linkage.
4536 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4538 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4553 Change LIBDEPS dependence to LIBS.
4555 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4557 * Makefile.in (install): if $(tooldir) exists, install as in
4560 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4562 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4563 .word is < -32768 or > 32767. The -J flag causes the error to be
4564 ignored. This is to catch over-sized switches generated by gcc on
4565 systems which don't support the broken .word hack.
4566 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4567 write.c (fixup_segment): check for signed .word overflow if
4568 WARN_SIGNED_OVERFLOW_WORD.
4570 * write.c (fixup_segment): fixed missing parens in expression
4571 checking for byte or word overflow.
4573 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

4587 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4589 * input-scrub.c (input_scrub_push): call input_file_begin, not
4591 messages.c (as_perror): print ": " between the passed in error and
4592 the strerror, like perror does.

4597 From Steve Chamberlain:
4598 Makefile.in: Handle m68*-*-coff*.
4599 read.c, read.h: add mult argument to s_space
4601 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4602 Motorola and MIT syntax; gas can now assemble either type of
4604 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4611 (fixup_segment) set fx_subsy to 0.
4612 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4614 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4617 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4619 * Makefile.in (LIBS): Include opcode library.
4621 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

4641 tc-i960.c (md_ri_to_chars): Always output bout object file in
4642 little endian byte order (used to use endianness of host).
4644 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4646 * config/tc-m68k.c (init_table): Now const. Always include 68851
4647 data, so that "bc" is available to 68040 cache instructions.
4648 Added "tt0", "tt1", and 68ec030 variants.
4649 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4650 (enum _register): Added TT0, TT1.
4651 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4652 line number correctly in "internal error" messages. Don't print
4653 architecture-mismatch message for operand errors.
4655 From Colin Smith (colin@wrs.com):
4656 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4657 than install_operand.

4661 * listing.c (buffer_line): rewind to the start of include
4662 files, they might be included twice.
4664 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
4666 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)

4669 one element of a family.
4671 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
4673 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4674 so that we can assemble hand-written libgcc code.
4676 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4678 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4679 has already been formatted (but may still contain %-characters).
4682 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4684 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4685 written with indirection on the last two operands, which can be
4686 either data or address registers. Added a new operand type 'r'
4687 which accepts either register type. Added '(' to notend stuff in
4688 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4690 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
4692 * as.h (enum _relax_state): Start off at one, not zero, to better

4701 data_last_frag): No longer static.
4702 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
4703 defined, call it. Change segments before calling fixup_segment.
4704 (relax_align): If linkrelax, provide extra padding.
4706 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4707 their not having symbols associated.
4709 * tc-i960.c (norelax, instrument_branches): Default initializer is
4711 (linkrelax): Delete variable definition.
4712 (mem_fmt): Call fix_new with NO_RELOC.

4798 processor/opcode mismatch, so reword the error message.
4799 (md_assemble): If no CPU has been set (even if FPU/PMMU
4800 characteristics have been), default to 68020. Don't need extra
4801 quotes around error string.

4883 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
4885 * write.c (write_object_file): keep the fix_tail clean, which
4886 fixes a bug in -R where relocations were being lost.
4888 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4890 * configure.in: recognize m680x0 as having sun3 emulation mode for

4935 start addresses to match required alignment.
4937 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4939 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4940 where gcc looks for it.
4942 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4944 * Makefile.in: Changed some lines to be less confusing for some

5010 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5012 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5014 * expr.c (operand): if can't work out what sort of operand it is,
5015 then look through FLT_CHARS for a hint.
5017 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5019 * Makefile.in, configure.in: removed traces of namesubdir,
5020 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5021 copyrights to '92, changed some from Cygnus to FSF.
5023 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5024 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5025 copyrights to '92, changed some from Cygnus to FSF.
5027 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5029 * expr.c: If an expression is single comma, then return with
5030 SEG_ABSENT rather than an error - since the sparc front end does
5031 really strange things with things like fbge,a
5033 * as.h: include bfd.h if using many sections
5034 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5035 local labels didn't work.
5036 * listing.c (list_symbol_table): don't core dump when there's no
5038 * write.c, write.h: call fix_new with the right number of args on
5040 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5043 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5045 * app.c: MRI compatibility - allow single quote to start a string.
5046 * as.c: fix typo recently introduced.
5047 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5048 * expr.c: Much rewriting, to accomodate MRI syntax for
5049 expressions. Also easier to read now.
5050 * listing.c: Put back defuns
5051 * read.c: modified to accept MRI syntax, put back listing pseudo
5052 ops so that an assembler built with NO_LISTING ignores list ops
5054 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5055 machine is a SPARC or a 29K.
5056 * config/obj-aout.c: added s_sect pseudo op
5057 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5058 fill in the timestamp.
5059 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5060 anymore, define all the relocs which the tc-<x> bit will use so we
5061 can translate from them to the coff types.
5062 * config/tc-a29k.c: reloc_type isn't ane enum any more
5063 * config/tc-m68k.c: Added NO_RELOC definition.
5065 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5067 * Makefile.in: put header files before C source for TAGS; remove
5068 references to non-existent syscalls.h.
5070 * read.c, write.c subsegs.c: back out the .bss changes.
5072 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5074 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5078 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5080 * symbols.c (local_label_name): symbols now start with ^A.
5082 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5083 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5084 generate these sections. .align: will use NOP_OPCODE or 0
5085 for padding. This is just for being nice to the
5088 * expr.c (operand): changed to generate local label "\001L0"
5089 starting with a ^A so that it is recognized as a local label.
5091 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5093 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5094 i/o opcodes - inb, inw, outb and outw. string manipulation with
5095 att syntax - scmp, slod, smov, ssca, ssto.
5097 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5098 to just after .file .
5100 In obj_crawl_symbol_chain() where it tries to put the external
5101 symbols apart, with the condition:
5102 (!S_IS_DEFINED(symbolP) &&
5103 !S_IS_DEBUG(symbolP) &&
5104 !SF_GET_STATICS(symbolP))
5105 it was moving too many symbols out. So I switch it back to the
5107 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5109 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5110 so that we don't use the F_RELFLG which make the linker complain
5111 that somebody has stripped the relocation info.
5113 Also, the AIX ld program require that the relocation table
5114 is sorted by r_vaddr like the standard ATT assembler does.
5116 [he also changed the sizeof(struct ...)'s into the coff
5117 style FOOSZ macros. I'm not sure this is right, but I can't
5118 remember why. xoxorich.]
5120 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5122 * Makefile.in, configure.in, doc: use the doc. Build it, install

5127 * read.c: white space and comments only.
5129 * configure.in: use the new atof-ns32.c for ns32k.
5131 * write.c: comment change only.
5133 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5134 aren't yet integrated.
5136 * tc-i860.[hc]: blew off the dust. Something must still be done
5137 about conflicting relocation types.
5139 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5142 * tc-i960.c, tc-sparc.c: white space and comments only.
5144 * tc-a29k.h: delete duplicate macro definition.
5146 * new file atof-ns32k.c copied from hack's last unreleased gas.
5148 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5150 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5153 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5154 ChangeLog's prior to this are sketchy at best. I have logs.
5155 They just aren't ChangeLogs.
