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

212 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
214 (reloc): Don't return 8 and 16 bit non-PC relative relocations on

2609 avoid some redefinition complaints on some systems.
2610 (const, volatile): Don't need these conditionally defined if we
2611 use CONST and VOLATILE from ansidecl.h.
2612 (seg_name): Use CONST, not const.
2614 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
2616 * config/tc-mips.c: Reindented to GNU standards.

2620 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

2627 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
2629 * Makefile.in: add dvi target; as-$(config).texinfo might live in
2630 srcdir, might be in objdir.

2649 * Makefile.in (targ-cpu.o): Depend on config.h.
2651 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
2653 * app.c (do_scrub_next_char): Added new state, 9, to avoid
2654 dropping a space immediately following an identifier.

2656 lines; I don't think that can be done portably.
2657 * config/tc-mips.c (macro): Use $AT if target register is zero in
2658 load instruction, which it can be for a floating point load.
2660 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

2681 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
2683 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
2684 to be on a single line.

2732 prototypes for all static functions. Moved existing minimal
2733 debugging format support info #ifndef OBJ_ECOFF blocks.

2782 * make-gas.com: Find obstack.obj if it's not in the current
2784 * read.c (s_ignore): Don't declare is_end_of_line. It's
2785 redundant, and triggers a VMS gcc compiler bug.
2787 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
2788 current segment as an argument. (Ignored in all cases but VMS.)
2789 All callers and definitions changed.

3086 md_relax_table): Use default zero initialization.
3087 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

3102 * expr.c (operand): If character other than comma or newline is a
3103 logical end-of-line character, use the newline case.
3104 From Eric Youngdale:
3105 (operand): Set X_add_number field for floating-point numbers.
3106 (operand): Treat zero byte as end-of-operand.
3108 * configure.in (per-target): Look for with_bfd_assembler option.
3109 For now, only accept "no", until the merge is done.
3111 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3112 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

3121 md_[long,short]_jump_size. Remove declaration of const_flag
3122 (which will be declared in obj-vms.h).
3123 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3124 Fix arguments to VMS_write_object_file.
3125 * config-gas.com: New file. Script for VMS systems to set up the

3134 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3135 types of malformed stabs. Change parsing algorithm so that we are
3136 more certain of having all of the information that we need on hand.
3137 * obj-vms.c (final_forward_reference): New function, used to help
3138 resolve the data types of as many struct elements as possible

3142 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3143 as symbols as well in the object file. Look for external functions

3146 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3148 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

3156 SEG_DATA or SEG_E1 if needed.
3157 (s_lcomm): Likewise with bss_section.
3158 (s_fill): Use memset, not bzero.

3185 mapping to segT enum values.
3186 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3187 if these are used or defined, if BFD_ASSEMBLER.
3188 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3189 subseg_new split into two functions.
3190 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3192 * as.h (volatile): Don't define if already defined.
3193 (had_errors, had_warnings): Provide prototypes for ANSI C even if

3213 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3214 (DOT_LABEL_PREFIX): Define.

3228 (size_section): Restored sanity check.
3229 (do_relocs_for): Base section address on s_paddr rather than
3230 computing it. Adjust a29k R_IHIHALF special case to account for

3232 reclos, set s_relptr to 0. Set relocation size in object_headers.
3233 (fill_section): Always set s_vaddr here, removing
3234 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3235 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3236 Set STYP_INFO for .comment.

3240 H_{SET,GET}_* macros.
3241 (do_linenos_for): Set lineno size in object_headers.
3242 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3243 set s_vaddr here. If string_byte_count remains 4, set it back to
3244 0, and only write strings out if there are some. Call
3245 fill_section before do_relocs_for and do_linenos_for.
3246 (obj_coff_section): Handle optional quoted second argument giving
3247 section characteristics.
3248 (obj_coff_bss): Added to handle .bss.

3275 * config/obj-coff.h: Don't use #elif.
3277 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3278 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3280 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
3282 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

3308 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3309 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3310 definitions, and don't merge tags with non-tags. Check for .bf
3311 rather than just checking whether the second character is b and
3312 the third character is f.
3313 (obj_coff_val): gcc can generate values which we don't handle
3314 correctly; discard information for now, since it only affects the
3315 debugging information.

3317 (yank_symbols): Don't merge labels.
3318 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3463 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
3464 could be doing emulation.
3466 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3469 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

3498 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
3500 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
3501 constant will not fit in an immediate field.
3502 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

3537 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
3539 * Support for i386-sysv.
3540 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

3544 (fill_section): Don't set STYP_NOLOAD for .bss section.
3545 (fixup_segment): 386 uses strange common symbol format.

3578 * tc-z8k.c: lots of bug fixes
3580 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
3582 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3583 #elif, since it is not supported by old compilers.
3584 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3585 couple of expressions in tc-m68k.c.
3587 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3589 * read.c (cons): If NO_RELOC is defined, use it.
3591 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
3593 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3595 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3596 local labels to start with a .) and set REGISTER_PREFIX to %.
3597 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
3599 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

3613 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
3615 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3616 sections starting from zero, rather than making them consecutive.
3617 This makes subsequent reloc calculations easier, esp if the object
3618 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3619 allocate lcomm in .data rather than in .bss. It seems that some
3620 tools can't cope with a non-zero sized bss before linkage.
3622 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3624 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
3625 throughout. That enum no longer means what we thought it meant.

3628 "-mno-688[58]1" options.
3630 * tc-m68k.c: Added CPU32 support.

3641 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
3643 * Makefile.in (install): if $(tooldir) exists, install as in
3646 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3648 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3649 .word is < -32768 or > 32767. The -J flag causes the error to be
3650 ignored. This is to catch over-sized switches generated by gcc on
3651 systems which don't support the broken .word hack.
3652 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3653 write.c (fixup_segment): check for signed .word overflow if
3654 WARN_SIGNED_OVERFLOW_WORD.
3656 * write.c (fixup_segment): fixed missing parens in expression
3657 checking for byte or word overflow.
3659 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

3673 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
3675 * input-scrub.c (input_scrub_push): call input_file_begin, not
3677 messages.c (as_perror): print ": " between the passed in error and
3678 the strerror, like perror does.

3683 From Steve Chamberlain:
3684 Makefile.in: Handle m68*-*-coff*.
3685 read.c, read.h: add mult argument to s_space
3687 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
3688 Motorola and MIT syntax; gas can now assemble either type of
3690 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

3696 (write_object_file) call fixup_mdeps
3697 (fixup_segment) set fx_subsy to 0.
3698 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
3700 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
3703 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3705 * Makefile.in (LIBS): Include opcode library.
3707 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

3727 tc-i960.c (md_ri_to_chars): Always output bout object file in
3728 little endian byte order (used to use endianness of host).
3730 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3732 * config/tc-m68k.c (init_table): Now const. Always include 68851
3733 data, so that "bc" is available to 68040 cache instructions.
3734 Added "tt0", "tt1", and 68ec030 variants.
3735 (md_assemble): Complain if 68000 (only) and 68881 are specified.
3736 (enum _register): Added TT0, TT1.
3737 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
3738 line number correctly in "internal error" messages. Don't print
3739 architecture-mismatch message for operand errors.
3741 From Colin Smith (colin@wrs.com):
3742 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
3743 than install_operand.
3745 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3747 * listing.c (buffer_line): rewind to the start of include
3748 files, they might be included twice.
3750 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
3752 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)

3755 one element of a family.
3757 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
3759 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
3760 so that we can assemble hand-written libgcc code.
3762 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3764 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
3765 has already been formatted (but may still contain %-characters).
3768 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
3770 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
3771 written with indirection on the last two operands, which can be
3772 either data or address registers. Added a new operand type 'r'
3773 which accepts either register type. Added '(' to notend stuff in
3774 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
3776 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
3778 * as.h (enum _relax_state): Start off at one, not zero, to better
3779 catch uninitialized-variable errors.

3787 data_last_frag): No longer static.
3788 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
3789 defined, call it. Change segments before calling fixup_segment.
3790 (relax_align): If linkrelax, provide extra padding.
3792 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
3793 their not having symbols associated.
3795 * tc-i960.c (norelax, instrument_branches): Default initializer is
3797 (linkrelax): Delete variable definition.
3798 (mem_fmt): Call fix_new with NO_RELOC.

3886 characteristics have been), default to 68020. Don't need extra
3887 quotes around error string.

3969 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
3971 * write.c (write_object_file): keep the fix_tail clean, which
3972 fixes a bug in -R where relocations were being lost.
3974 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
3976 * configure.in: recognize m680x0 as having sun3 emulation mode for

4021 start addresses to match required alignment.
4023 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4025 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4026 where gcc looks for it.
4028 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4030 * Makefile.in: Changed some lines to be less confusing for some

4096 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4098 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4100 * expr.c (operand): if can't work out what sort of operand it is,
4101 then look through FLT_CHARS for a hint.
4103 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4105 * Makefile.in, configure.in: removed traces of namesubdir,
4106 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4107 copyrights to '92, changed some from Cygnus to FSF.
4109 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4110 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4111 copyrights to '92, changed some from Cygnus to FSF.
4113 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4115 * expr.c: If an expression is single comma, then return with
4116 SEG_ABSENT rather than an error - since the sparc front end does
4117 really strange things with things like fbge,a
4119 * as.h: include bfd.h if using many sections
4120 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4121 local labels didn't work.
4122 * listing.c (list_symbol_table): don't core dump when there's no
4124 * write.c, write.h: call fix_new with the right number of args on
4126 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4129 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4131 * app.c: MRI compatibility - allow single quote to start a string.
4132 * as.c: fix typo recently introduced.
4133 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4134 * expr.c: Much rewriting, to accomodate MRI syntax for
4135 expressions. Also easier to read now.
4136 * listing.c: Put back defuns
4137 * read.c: modified to accept MRI syntax, put back listing pseudo
4138 ops so that an assembler built with NO_LISTING ignores list ops
4140 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4141 machine is a SPARC or a 29K.
4142 * config/obj-aout.c: added s_sect pseudo op
4143 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4144 fill in the timestamp.
4145 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4146 anymore, define all the relocs which the tc-<x> bit will use so we
4147 can translate from them to the coff types.
4148 * config/tc-a29k.c: reloc_type isn't ane enum any more
4149 * config/tc-m68k.c: Added NO_RELOC definition.
4151 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4153 * Makefile.in: put header files before C source for TAGS; remove
4154 references to non-existent syscalls.h.
4156 * read.c, write.c subsegs.c: back out the .bss changes.
4158 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4160 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4164 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4166 * symbols.c (local_label_name): symbols now start with ^A.
4168 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4169 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4170 generate these sections. .align: will use NOP_OPCODE or 0
4171 for padding. This is just for being nice to the
4174 * expr.c (operand): changed to generate local label "\001L0"
4175 starting with a ^A so that it is recognized as a local label.
4177 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4179 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4180 i/o opcodes - inb, inw, outb and outw. string manipulation with
4181 att syntax - scmp, slod, smov, ssca, ssto.
4183 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4184 to just after .file .
4186 In obj_crawl_symbol_chain() where it tries to put the external
4187 symbols apart, with the condition:
4188 (!S_IS_DEFINED(symbolP) &&
4189 !S_IS_DEBUG(symbolP) &&
4190 !SF_GET_STATICS(symbolP))
4191 it was moving too many symbols out. So I switch it back to the
4193 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4195 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4196 so that we don't use the F_RELFLG which make the linker complain
4197 that somebody has stripped the relocation info.
4199 Also, the AIX ld program require that the relocation table
4200 is sorted by r_vaddr like the standard ATT assembler does.
4202 [he also changed the sizeof(struct ...)'s into the coff
4203 style FOOSZ macros. I'm not sure this is right, but I can't
4204 remember why. xoxorich.]
4206 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4208 * Makefile.in, configure.in, doc: use the doc. Build it, install
4211 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4213 * read.c: white space and comments only.
4215 * configure.in: use the new atof-ns32.c for ns32k.
4217 * write.c: comment change only.
4219 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4220 aren't yet integrated.
4222 * tc-i860.[hc]: blew off the dust. Something must still be done
4223 about conflicting relocation types.
4225 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4228 * tc-i960.c, tc-sparc.c: white space and comments only.
4230 * tc-a29k.h: delete duplicate macro definition.
4232 * new file atof-ns32k.c copied from hack's last unreleased gas.
4234 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4236 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4239 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4240 ChangeLog's prior to this are sketchy at best. I have logs.
4241 They just aren't ChangeLogs.
