535 OPTIONAL_REGISTER_PREFIX if either is already defined.
537 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
539 * configure.in: Set bfd_gas for all sparc targets. Added facility
540 for keeping or rejecting configurations still under development;
541 default is to assume production environment, and reject configs
542 still being worked on. Mark Elf configurations (except sparc and
543 i386) as developmental. Deleted cases matching some generic names
544 in favor of more specific names. (E.g., when we get Alpha
545 support, we'll still only support VMS for Vax.)

561 through inclusion of tc-hppa.h. Delete all forward declarations
562 for functions only used within tc-hppa.c, likewise for structures,
563 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
564 conditional code in a few small places.
566 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
567 structures, global variables, forward declarations together.

569 conditional code -- try to group conditional code together
570 into a few places. Make all functions and variables which
571 are only used within tc-hppa.c static. PARAMize all functions.
572 Add comments to functions. Delete unused functions, variables,
573 #defines, etc. Delete unused members within structures. Delete
574 ldil;ble hacks -- it is believed they were installed to work
575 around old gas bugs. Avoid using mixed case for local
576 functions, variables, and structures. Fix formatting problems
577 not found by GNU-indent. Add FIXME notices for things which
578 should be worked on the near future. Delete lots of old
579 useless (1.36 PA-SOM) code.

591 which do not involve function symbols.
593 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
594 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
596 * config/tc-hppa.c: Likewise.
598 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
599 of elf32_symbol_type.
600 (pa_export_args): Likewise.
601 (elf_hppa_final_processing): Likewise.
602 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

608 a multiple of the section alignment rather than always a
611 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
612 bits are zero (eg they specify no relocations), then do not even

652 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
654 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
655 ELF, since the ELF object format does not have these type of
656 relocations. Change the abort into as as_bad and return
657 BFD_RELOC_NONE to silence compiler warnings.

2935 than ECOFF line number information.
2936 (obj_ecoff_stab): Accept non-zero values for stabs line number.

2938 to small, undefined and/or readonly sections if appropriate.
2939 Don't output symbol names containing \001 characters.
2940 (ecoff_frob_file): Make sure at least one fdr is output.

2997 dependencies are read, not when they are used).
2999 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
3000 a29k .bss section; the mondfe program doesn't like it.

3021 source directory, if that's not the current directory.
3023 * configure.in (per-host): Accept MIPS host with BSD version

3049 avoid some redefinition complaints on some systems.
3050 (const, volatile): Don't need these conditionally defined if we
3051 use CONST and VOLATILE from ansidecl.h.
3052 (seg_name): Use CONST, not const.
3054 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3056 * config/tc-mips.c: Reindented to GNU standards.

3060 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3061 (fixup_segment): Add a29k special case; the linker is not prepared
3062 to see a segment offset here.
3064 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3067 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3069 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3070 srcdir, might be in objdir.

3085 bignums, but don't emit error message.
3087 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3089 * Makefile.in (targ-cpu.o): Depend on config.h.
3091 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3093 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3094 dropping a space immediately following an identifier.
3095 * expr.c, write.c: Rewrote assert expressions to not use multiple
3096 lines; I don't think that can be done portably.
3097 * config/tc-mips.c (macro): Use $AT if target register is zero in
3098 load instruction, which it can be for a floating point load.
3100 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3114 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
3117 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

3121 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3123 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3124 to be on a single line.

3171 * config/tc-mips.c: Rearranged for ECOFF support. Added
3172 prototypes for all static functions. Moved existing minimal
3173 debugging format support info #ifndef OBJ_ECOFF blocks.

3222 * make-gas.com: Find obstack.obj if it's not in the current
3224 * read.c (s_ignore): Don't declare is_end_of_line. It's
3225 redundant, and triggers a VMS gcc compiler bug.
3227 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3228 current segment as an argument. (Ignored in all cases but VMS.)
3229 All callers and definitions changed.

3247 argument to s_ignore. Put "#if 0" around unused code.
3248 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
3249 Call elf_xstabs for .stabs and .xstabs operators.

3526 md_relax_table): Use default zero initialization.
3527 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3528 latter, instead of selecting with preprocessor conditionals.
3530 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3532 * configure.in: recognise all sparclite variants

3542 * expr.c (operand): If character other than comma or newline is a
3543 logical end-of-line character, use the newline case.
3544 From Eric Youngdale:
3545 (operand): Set X_add_number field for floating-point numbers.
3546 (operand): Treat zero byte as end-of-operand.
3548 * configure.in (per-target): Look for with_bfd_assembler option.
3549 For now, only accept "no", until the merge is done.
3551 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3552 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

3554 * read.c: Finish conversion to S_* macros in the VMS only
3555 parts of the program. Add "const" modifier to hex_value.
3556 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
3558 * expr.c: Add "const" modifier to hex_value.
3559 * symbols.c: Finish conversion to S_* macros in the VMS only
3560 parts of the program. Add "const" modifier to
3561 md_[long,short]_jump_size. Remove declaration of const_flag
3562 (which will be declared in obj-vms.h).
3563 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3564 Fix arguments to VMS_write_object_file.
3565 * config-gas.com: New file. Script for VMS systems to set up the
3566 configuration to build gas for VMS, and create config.status.
3567 * make-gas.com: Redone to work with new scheme.
3568 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3570 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

3573 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3574 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3575 types of malformed stabs. Change parsing algorithm so that we are
3576 more certain of having all of the information that we need on hand.
3577 * obj-vms.c (final_forward_reference): New function, used to help
3578 resolve the data types of as many struct elements as possible
3579 when some part of the struct is not fully defined by the compiler.

3582 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3583 as symbols as well in the object file. Look for external functions
3584 that start with "__vt.", and turn them into variables, since the
3585 g++ compiler is incapable of doing this.
3586 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3588 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3589 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3590 have the name of the source file yet.
3591 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3593 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3595 * read.c (s_data): Always use "data_section", since it'll map to
3596 SEG_DATA or SEG_E1 if needed.
3597 (s_lcomm): Likewise with bss_section.
3598 (s_fill): Use memset, not bzero.
3600 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3622 (big_section, reg_section, pass1_section, diff_section,
3623 absent_section, text_section, data_section, bss_section): If
3624 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3625 mapping to segT enum values.
3626 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3627 if these are used or defined, if BFD_ASSEMBLER.
3628 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3629 subseg_new split into two functions.
3630 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3632 * as.h (volatile): Don't define if already defined.
3633 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3635 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3636 declare with format attribute for -Wformat checking.
3638 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3640 * app.c, config/tc-*.c: Don't include read.h, since it is already
3643 * These are based on patches from Minh Tran-le
3644 <mtranle@paris.intellicorp.com>.
3645 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3646 obj_format coffbfd and gas_target i386coff for target.
3647 (i[34]86-*-isc*): New host (uses sysv).
3648 * config/i386aix.mt: Removed (no longer used).
3649 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3651 (LDFLAGS): Added, defined as -shlib.
3652 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3653 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3654 (DOT_LABEL_PREFIX): Define.
3655 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3656 name rather than L0\001.
3657 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3659 * symbols.c, symbols.h (local_bss_counter): Removed.

3668 (size_section): Restored sanity check.
3669 (do_relocs_for): Base section address on s_paddr rather than
3670 computing it. Adjust a29k R_IHIHALF special case to account for
3671 section paddr (used to require paddr to be zero). If there are no
3672 reclos, set s_relptr to 0. Set relocation size in object_headers.
3673 (fill_section): Always set s_vaddr here, removing
3674 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3675 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3676 Set STYP_INFO for .comment.
3677 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
3678 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

3680 H_{SET,GET}_* macros.
3681 (do_linenos_for): Set lineno size in object_headers.
3682 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3683 set s_vaddr here. If string_byte_count remains 4, set it back to
3684 0, and only write strings out if there are some. Call
3685 fill_section before do_relocs_for and do_linenos_for.
3686 (obj_coff_section): Handle optional quoted second argument giving
3687 section characteristics.
3688 (obj_coff_bss): Added to handle .bss.
3689 (obj_coff_ident): Added to handle .ident (puts string in .comment

3709 (do_scrub_next_char): For \", return " not '.
3710 (symbol_chars): Now const.
3712 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3713 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3715 * config/obj-coff.h: Don't use #elif.
3717 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3718 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3720 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
3722 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

3736 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
3738 * listing.c: Call xmalloc, not malloc; don't declare malloc.
3740 * Changes to support SCO 3.2v4:
3741 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
3742 SEG_BSS, fill with NOP_OPCODE.
3743 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
3744 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
3745 using ZERO_BASED_SEGMENTS.
3746 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3747 never set segment address for SEG_E2 (.bss) and don't write out
3748 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3749 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3750 definitions, and don't merge tags with non-tags. Check for .bf
3751 rather than just checking whether the second character is b and
3752 the third character is f.
3753 (obj_coff_val): gcc can generate values which we don't handle
3754 correctly; discard information for now, since it only affects the
3755 debugging information.
3756 (tag_find_or_name): Don't insert tags in the symbol table.
3757 (yank_symbols): Don't merge labels.
3758 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3904 could be doing emulation.
3906 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3909 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

3938 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
3940 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
3941 constant will not fit in an immediate field.
3942 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

3977 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
3979 * Support for i386-sysv.
3980 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4018 * tc-z8k.c: lots of bug fixes
4020 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4022 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4023 #elif, since it is not supported by old compilers.
4024 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4025 couple of expressions in tc-m68k.c.
4027 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4029 * read.c (cons): If NO_RELOC is defined, use it.
4031 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4033 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4035 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4036 local labels to start with a .) and set REGISTER_PREFIX to %.
4037 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4039 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4053 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4055 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4056 sections starting from zero, rather than making them consecutive.
4057 This makes subsequent reloc calculations easier, esp if the object
4058 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4059 allocate lcomm in .data rather than in .bss. It seems that some
4060 tools can't cope with a non-zero sized bss before linkage.
4062 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4064 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4083 * Makefile.in (install): if $(tooldir) exists, install as in
4086 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4088 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4089 .word is < -32768 or > 32767. The -J flag causes the error to be
4090 ignored. This is to catch over-sized switches generated by gcc on
4091 systems which don't support the broken .word hack.
4092 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4093 write.c (fixup_segment): check for signed .word overflow if
4094 WARN_SIGNED_OVERFLOW_WORD.
4096 * write.c (fixup_segment): fixed missing parens in expression
4097 checking for byte or word overflow.

4113 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4115 * input-scrub.c (input_scrub_push): call input_file_begin, not
4117 messages.c (as_perror): print ": " between the passed in error and
4118 the strerror, like perror does.

4123 From Steve Chamberlain:
4124 Makefile.in: Handle m68*-*-coff*.
4125 read.c, read.h: add mult argument to s_space
4127 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4128 Motorola and MIT syntax; gas can now assemble either type of
4130 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4136 (write_object_file) call fixup_mdeps
4137 (fixup_segment) set fx_subsy to 0.
4138 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4140 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4143 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4145 * Makefile.in (LIBS): Include opcode library.
4147 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

4170 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4172 * config/tc-m68k.c (init_table): Now const. Always include 68851
4173 data, so that "bc" is available to 68040 cache instructions.
4174 Added "tt0", "tt1", and 68ec030 variants.
4175 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4176 (enum _register): Added TT0, TT1.
4177 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4178 line number correctly in "internal error" messages. Don't print
4179 architecture-mismatch message for operand errors.
4181 From Colin Smith (colin@wrs.com):
4182 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4183 than install_operand.

4187 * listing.c (buffer_line): rewind to the start of include
4188 files, they might be included twice.

4197 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
4199 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4200 so that we can assemble hand-written libgcc code.
4202 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4204 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4205 has already been formatted (but may still contain %-characters).
4208 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4210 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4211 written with indirection on the last two operands, which can be
4212 either data or address registers. Added a new operand type 'r'
4213 which accepts either register type. Added '(' to notend stuff in
4214 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4216 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
4218 * as.h (enum _relax_state): Start off at one, not zero, to better

4229 defined, call it. Change segments before calling fixup_segment.
4230 (relax_align): If linkrelax, provide extra padding.
4232 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4233 their not having symbols associated.
4235 * tc-i960.c (norelax, instrument_branches): Default initializer is
4237 (linkrelax): Delete variable definition.

4261 being used with args swapped, causing occasional lossage when
4262 refilling buffers after an include file.

4266 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
4267 version. Discard bogus DONTDEF version.
4268 (as_warn, as_bad, as_fatal): Likewise.
4270 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)

4324 processor/opcode mismatch, so reword the error message.
4325 (md_assemble): If no CPU has been set (even if FPU/PMMU
4326 characteristics have been), default to 68020. Don't need extra
4327 quotes around error string.

4409 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
4411 * write.c (write_object_file): keep the fix_tail clean, which
4412 fixes a bug in -R where relocations were being lost.
4414 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4416 * configure.in: recognize m680x0 as having sun3 emulation mode for

4463 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4465 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4466 where gcc looks for it.
4468 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4470 * Makefile.in: Changed some lines to be less confusing for some

4536 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4538 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4540 * expr.c (operand): if can't work out what sort of operand it is,
4541 then look through FLT_CHARS for a hint.
4543 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4545 * Makefile.in, configure.in: removed traces of namesubdir,
4546 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4547 copyrights to '92, changed some from Cygnus to FSF.
4549 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4550 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4551 copyrights to '92, changed some from Cygnus to FSF.
4553 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4555 * expr.c: If an expression is single comma, then return with
4556 SEG_ABSENT rather than an error - since the sparc front end does
4557 really strange things with things like fbge,a
4559 * as.h: include bfd.h if using many sections
4560 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4561 local labels didn't work.
4562 * listing.c (list_symbol_table): don't core dump when there's no
4564 * write.c, write.h: call fix_new with the right number of args on
4566 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4569 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4571 * app.c: MRI compatibility - allow single quote to start a string.
4572 * as.c: fix typo recently introduced.
4573 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4574 * expr.c: Much rewriting, to accomodate MRI syntax for
4575 expressions. Also easier to read now.
4576 * listing.c: Put back defuns
4577 * read.c: modified to accept MRI syntax, put back listing pseudo
4578 ops so that an assembler built with NO_LISTING ignores list ops
4580 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4581 machine is a SPARC or a 29K.
4582 * config/obj-aout.c: added s_sect pseudo op
4583 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4584 fill in the timestamp.
4585 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4586 anymore, define all the relocs which the tc-<x> bit will use so we
4587 can translate from them to the coff types.
4588 * config/tc-a29k.c: reloc_type isn't ane enum any more
4589 * config/tc-m68k.c: Added NO_RELOC definition.
4591 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4593 * Makefile.in: put header files before C source for TAGS; remove
4594 references to non-existent syscalls.h.
4596 * read.c, write.c subsegs.c: back out the .bss changes.
4598 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4600 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4604 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4606 * symbols.c (local_label_name): symbols now start with ^A.
4608 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4609 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4610 generate these sections. .align: will use NOP_OPCODE or 0
4611 for padding. This is just for being nice to the
4614 * expr.c (operand): changed to generate local label "\001L0"
4615 starting with a ^A so that it is recognized as a local label.
4617 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4619 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4620 i/o opcodes - inb, inw, outb and outw. string manipulation with
4621 att syntax - scmp, slod, smov, ssca, ssto.
4623 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4624 to just after .file .
4626 In obj_crawl_symbol_chain() where it tries to put the external
4627 symbols apart, with the condition:
4628 (!S_IS_DEFINED(symbolP) &&
4629 !S_IS_DEBUG(symbolP) &&
4630 !SF_GET_STATICS(symbolP))
4631 it was moving too many symbols out. So I switch it back to the
4633 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4635 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4636 so that we don't use the F_RELFLG which make the linker complain
4637 that somebody has stripped the relocation info.
4639 Also, the AIX ld program require that the relocation table
4640 is sorted by r_vaddr like the standard ATT assembler does.
4642 [he also changed the sizeof(struct ...)'s into the coff
4643 style FOOSZ macros. I'm not sure this is right, but I can't
4644 remember why. xoxorich.]
4646 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4648 * Makefile.in, configure.in, doc: use the doc. Build it, install

4653 * read.c: white space and comments only.
4655 * configure.in: use the new atof-ns32.c for ns32k.
4657 * write.c: comment change only.
4659 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4660 aren't yet integrated.
4662 * tc-i860.[hc]: blew off the dust. Something must still be done
4663 about conflicting relocation types.
4665 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4668 * tc-i960.c, tc-sparc.c: white space and comments only.
4670 * tc-a29k.h: delete duplicate macro definition.
4672 * new file atof-ns32k.c copied from hack's last unreleased gas.
4674 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4676 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4679 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4680 ChangeLog's prior to this are sketchy at best. I have logs.
4681 They just aren't ChangeLogs.
