1503 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1504 the table, require that the one without bit 0x1000000 set come
1505 first. Require further that it be case 'b' or 'P'. The a29k
1506 opcode table already meets these constraints.
1507 (machine_ip): When handling case 'i' or 'A', make sure that the

1556 as.info* even if they're in $(srcdir) (e.g., for FSF
1559 * write.c (write_relocs): For relocs that are pc_relative and
1560 pcrel_offset and not partial_inplace, adjust reloc->addend to

1616 for keeping or rejecting configurations still under development;
1617 default is to assume production environment, and reject configs
1618 still being worked on. Mark Elf configurations (except sparc and
1619 i386) as developmental. Deleted cases matching some generic names
1620 in favor of more specific names. (E.g., when we get Alpha

1637 through inclusion of tc-hppa.h. Delete all forward declarations
1638 for functions only used within tc-hppa.c, likewise for structures,
1639 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1640 conditional code in a few small places.
1642 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1643 structures, global variables, forward declarations together.

1645 conditional code -- try to group conditional code together
1646 into a few places. Make all functions and variables which
1647 are only used within tc-hppa.c static. PARAMize all functions.
1648 Add comments to functions. Delete unused functions, variables,
1649 #defines, etc. Delete unused members within structures. Delete
1650 ldil;ble hacks -- it is believed they were installed to work
1651 around old gas bugs. Avoid using mixed case for local
1652 functions, variables, and structures. Fix formatting problems
1653 not found by GNU-indent. Add FIXME notices for things which
1654 should be worked on the near future. Delete lots of old
1655 useless (1.36 PA-SOM) code.

1672 * config/tc-hppa.c: Likewise.
1674 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
1675 of elf32_symbol_type.
1676 (pa_export_args): Likewise.

1683 * config/tc-hppa.c: (md_section_align): Align all sections to
1684 a multiple of the section alignment rather than always a
1687 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
1688 bits are zero (eg they specify no relocations), then do not even
1689 bother adding their entries to thesymextn section.

1718 * config/tc-i386.c (md_apply_fix_1): Make cross segment calls work
1719 for ELF by hacking around bizarre bfd_perform_relocation behaviour
1720 that I don't dare change.

1727 of text, data and bss sections to 4.
1728 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1730 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1731 ELF, since the ELF object format does not have these type of
1732 relocations. Change the abort into as as_bad and return
1733 BFD_RELOC_NONE to silence compiler warnings.
1734 (md_assemble): Keep track of the instruction size. Allow white
1735 space between the $ and the constant for compatibility with older
1736 gases and other assemblers.
1737 (i386_operand): Skip spaces between $ and expression.
1738 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

4136 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

4173 * config/tc-mips.c (macro): Use $AT if target register is zero in
4174 load instruction, which it can be for a floating point load.

4248 prototypes for all static functions. Moved existing minimal
4249 debugging format support info #ifndef OBJ_ECOFF blocks.

4300 * read.c (s_ignore): Don't declare is_end_of_line. It's
4301 redundant, and triggers a VMS gcc compiler bug.
4303 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4304 current segment as an argument. (Ignored in all cases but VMS.)

4622 (operand): Treat zero byte as end-of-operand.
4624 * configure.in (per-target): Look for with_bfd_assembler option.
4625 For now, only accept "no", until the merge is done.
4627 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4628 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4634 * expr.c: Add "const" modifier to hex_value.
4635 * symbols.c: Finish conversion to S_* macros in the VMS only
4636 parts of the program. Add "const" modifier to
4637 md_[long,short]_jump_size. Remove declaration of const_flag
4638 (which will be declared in obj-vms.h).
4639 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4640 Fix arguments to VMS_write_object_file.
4641 * config-gas.com: New file. Script for VMS systems to set up the
4642 configuration to build gas for VMS, and create config.status.

4701 mapping to segT enum values.
4702 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4703 if these are used or defined, if BFD_ASSEMBLER.
4704 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4705 subseg_new split into two functions.
4706 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4708 * as.h (volatile): Don't define if already defined.
4709 (had_errors, had_warnings): Provide prototypes for ANSI C even if

4716 * app.c, config/tc-*.c: Don't include read.h, since it is already
4719 * These are based on patches from Minh Tran-le
4720 <mtranle@paris.intellicorp.com>.
4721 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4722 obj_format coffbfd and gas_target i386coff for target.
4723 (i[34]86-*-isc*): New host (uses sysv).
4724 * config/i386aix.mt: Removed (no longer used).
4725 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4727 (LDFLAGS): Added, defined as -shlib.
4728 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4729 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4730 (DOT_LABEL_PREFIX): Define.
4731 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4732 name rather than L0\001.
4733 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4735 * symbols.c, symbols.h (local_bss_counter): Removed.
4736 * write.c (write_object_file): bss no longer uses
4737 local_bss_counter. Pass correct data and bss size to
4738 VMS_write_object_file.
4739 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
4740 argument, rather than using local_bss_counter.

4742 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
4743 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
4744 (size_section): Restored sanity check.
4745 (do_relocs_for): Base section address on s_paddr rather than
4746 computing it. Adjust a29k R_IHIHALF special case to account for
4747 section paddr (used to require paddr to be zero). If there are no
4748 reclos, set s_relptr to 0. Set relocation size in object_headers.
4749 (fill_section): Always set s_vaddr here, removing
4750 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4751 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4752 Set STYP_INFO for .comment.
4753 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4754 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
4755 (crawl_symbols): Handle 8 character section name correctly. Use
4756 H_{SET,GET}_* macros.
4757 (do_linenos_for): Set lineno size in object_headers.
4758 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4759 set s_vaddr here. If string_byte_count remains 4, set it back to
4760 0, and only write strings out if there are some. Call
4761 fill_section before do_relocs_for and do_linenos_for.
4762 (obj_coff_section): Handle optional quoted second argument giving
4763 section characteristics.
4764 (obj_coff_bss): Added to handle .bss.
4765 (obj_coff_ident): Added to handle .ident (puts string in .comment
4767 (obj_coff_lcomm): Put common symbols in .bss, not .data.
4768 (fixup_mdeps): Change to segment. Call frag_wane after
4770 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4771 adjustment (already happened only for common symbols, but this is
4773 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
4774 * config/tc-i386.c (s_bss): Don't use if I386COFF.

4780 (DOT_LABEL_PREFIX): Defined.
4782 Mon Dec 28 10:32:05 1992 Ken Raeburn (raeburn@cygnus.com)
4784 * app.c (app_push): Use memcpy, not bcopy.
4785 (do_scrub_next_char): For \", return " not '.
4786 (symbol_chars): Now const.
4788 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4789 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4791 * config/obj-coff.h: Don't use #elif.
4793 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4794 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4796 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

4818 SEG_BSS, fill with NOP_OPCODE.
4819 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
4820 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4821 using ZERO_BASED_SEGMENTS.
4822 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4823 never set segment address for SEG_E2 (.bss) and don't write out
4824 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4825 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4826 definitions, and don't merge tags with non-tags. Check for .bf
4827 rather than just checking whether the second character is b and
4828 the third character is f.
4829 (obj_coff_val): gcc can generate values which we don't handle
4830 correctly; discard information for now, since it only affects the
4831 debugging information.
4832 (tag_find_or_name): Don't insert tags in the symbol table.
4833 (yank_symbols): Don't merge labels.
4834 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4837 (obj_coff_section): Accept and ignore a trailing quoted string, as
4838 used in AT&T i386 syntax.
4839 (fixup_segment): Take segment as argument. On the i386, adjust PC
4840 relative addends by the segment vaddr.
4841 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
4842 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

4854 power-of-two alignment for .align.
4856 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
4857 and leave everything else alone.

4889 options. Updated options documentation for m68k. Some minor
4890 wording/punctuation changes.

4979 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
4980 could be doing emulation.
4982 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4985 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
4988 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

5014 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5016 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5017 constant will not fit in an immediate field.
5018 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
5020 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

5053 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5055 * Support for i386-sysv.
5056 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5080 * tc-m68k.c (get_num): make it work for all segments, not just the
5083 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5085 * configure.in: recognize i386-*-bsd emulation.

5094 * tc-z8k.c: lots of bug fixes
5096 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5098 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5099 #elif, since it is not supported by old compilers.
5100 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5101 couple of expressions in tc-m68k.c.
5103 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5105 * read.c (cons): If NO_RELOC is defined, use it.
5107 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5109 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5111 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5112 local labels to start with a .) and set REGISTER_PREFIX to %.
5113 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5115 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
5117 * messages.c: Comment changes.
5119 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

5122 * messages.c: If __STDC__ is not defined, define NO_STDARG.
5124 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
5126 * listing.c (debugging_pseudo): Add stabs and stabn as things to
5129 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5131 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5132 sections starting from zero, rather than making them consecutive.
5133 This makes subsequent reloc calculations easier, esp if the object
5134 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5135 allocate lcomm in .data rather than in .bss. It seems that some
5136 tools can't cope with a non-zero sized bss before linkage.
5138 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5140 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5141 throughout. That enum no longer means what we thought it meant.
5143 * tc-m68k.c (md_assemble, md_parse_option): Handle new
5144 "-mno-688[58]1" options.
5146 * tc-m68k.c: Added CPU32 support.
5148 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5150 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
5152 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5154 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
5155 Change LIBDEPS dependence to LIBS.
5157 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
5159 * Makefile.in (install): if $(tooldir) exists, install as in
5162 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5164 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5165 .word is < -32768 or > 32767. The -J flag causes the error to be
5166 ignored. This is to catch over-sized switches generated by gcc on
5167 systems which don't support the broken .word hack.
5168 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5169 write.c (fixup_segment): check for signed .word overflow if
5170 WARN_SIGNED_OVERFLOW_WORD.
5172 * write.c (fixup_segment): fixed missing parens in expression
5173 checking for byte or word overflow.
5175 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
5176 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
5177 WARN_SIGNED_OVERFLOW_WORD.

5185 * obj-coffbfd.h : added stuff
5186 * tc-i386.c (tc_coff_fix2rtype): new function
5187 * tc-i386.h : new coff defines
5189 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5191 * input-scrub.c (input_scrub_push): call input_file_begin, not
5193 messages.c (as_perror): print ": " between the passed in error and
5194 the strerror, like perror does.
5196 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
5198 * Makefile.in: use gas_target instead of modifying target_cpu.
5199 From Steve Chamberlain:

5286 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5287 written with indirection on the last two operands, which can be
5288 either data or address registers. Added a new operand type 'r'
5289 which accepts either register type. Added '(' to notend stuff in
5290 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5629 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5631 * expr.c: If an expression is single comma, then return with
5632 SEG_ABSENT rather than an error - since the sparc front end does
5633 really strange things with things like fbge,a
5635 * as.h: include bfd.h if using many sections
5636 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so

5650 * expr.c: Much rewriting, to accomodate MRI syntax for
5651 expressions. Also easier to read now.
5652 * listing.c: Put back defuns
5653 * read.c: modified to accept MRI syntax, put back listing pseudo
5654 ops so that an assembler built with NO_LISTING ignores list ops
5656 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5657 machine is a SPARC or a 29K.
5658 * config/obj-aout.c: added s_sect pseudo op
5659 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5660 fill in the timestamp.
5661 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5662 anymore, define all the relocs which the tc-<x> bit will use so we
5663 can translate from them to the coff types.
5664 * config/tc-a29k.c: reloc_type isn't ane enum any more
5665 * config/tc-m68k.c: Added NO_RELOC definition.

5684 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5685 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5686 generate these sections. .align: will use NOP_OPCODE or 0
5687 for padding. This is just for being nice to the
5690 * expr.c (operand): changed to generate local label "\001L0"
5691 starting with a ^A so that it is recognized as a local label.
5693 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5695 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5696 i/o opcodes - inb, inw, outb and outw. string manipulation with
5697 att syntax - scmp, slod, smov, ssca, ssto.
5699 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5700 to just after .file .
5702 In obj_crawl_symbol_chain() where it tries to put the external
5703 symbols apart, with the condition:
5704 (!S_IS_DEFINED(symbolP) &&
5705 !S_IS_DEBUG(symbolP) &&
5706 !SF_GET_STATICS(symbolP))
5707 it was moving too many symbols out. So I switch it back to the
5709 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5711 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5712 so that we don't use the F_RELFLG which make the linker complain
5713 that somebody has stripped the relocation info.
5715 Also, the AIX ld program require that the relocation table
5716 is sorted by r_vaddr like the standard ATT assembler does.
5718 [he also changed the sizeof(struct ...)'s into the coff
5719 style FOOSZ macros. I'm not sure this is right, but I can't
5720 remember why. xoxorich.]

5724 * Makefile.in, configure.in, doc: use the doc. Build it, install
5727 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5729 * read.c: white space and comments only.
5731 * configure.in: use the new atof-ns32.c for ns32k.
5733 * write.c: comment change only.
5735 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5736 aren't yet integrated.
5738 * tc-i860.[hc]: blew off the dust. Something must still be done
5739 about conflicting relocation types.
5741 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5744 * tc-i960.c, tc-sparc.c: white space and comments only.
5746 * tc-a29k.h: delete duplicate macro definition.
5748 * new file atof-ns32k.c copied from hack's last unreleased gas.

5752 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5755 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5756 ChangeLog's prior to this are sketchy at best. I have logs.
5757 They just aren't ChangeLogs.
