        * config/tc-mips.c: Include opcode/mips.h rather than
        mips-opcode.h.
        (append_insn): An extra NOP is only needed after instructions
        which set HI or LO, not after instructions which read it.
        (macro_build, mips_ip): Support new 'E', 'G' and 'B' arguments.
        (macro): cfc1 and ctc1 now take "t,G" rather than "t,d".
        * config/tc-mips.h (struct mips_opcode): Don't define.
        * config/mips-big.mt, config/mips-lit.mt (TARG_CPU_DEPENDENTS):
        Set to $(srcdir)/../include/opcode/mips.h.

        Get the MIPS assembler up to speed with other gas changes:

        * config/obj-ecoff.c (ecoff_set_vma, ecoff_frob_symbol):
        Removed; don't change the symbol value.
        (ecoff_build_symbols, ecoff_build_procs, ecoff_frob_file): Use
        bfd_asymbol_value rather than S_GET_VALUE to include section
        vma in symbol value.
        (ecoff_frob_file): Ignore BSF_SECTION_SYM symbols, since ECOFF
        doesn't output them.  Set the vma of sections.
        * config/obj-ecoff.h: Don't define obj_frob_symbol.
        * config/tc-mips.c (tc_gen_reloc): Adjustment by section vma is no

        * configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
        the bottom (make expands variables in dependencies when the
        dependencies are read, not when they are used).

        * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
        a29k .bss section; the mondfe program doesn't like it.

        this directory.
        (srcdir): Delete second, bogus definition.
        (as.info): Look for as-*.texinfo in current directory rather than

        process relocs if there aren't any relocs to process.  Avoids
        malloc/free bug on SCO too.

        * as.h: Move local include files below system include files, to
        avoid some redefinition complaints on some systems.
        (const, volatile): Don't need these conditionally defined if we
        use CONST and VOLATILE from ansidecl.h.
        (seg_name): Use CONST, not const.

Wed Mar 24 02:16:22 1993  david d `zoo' zuhn  (zoo at poseidon.cygnus.com)

        * Makefile.in: add dvi target; as-$(config).texinfo might live in
        srcdir, might be in objdir.

        dropping a space immediately following an identifier.

        lines; I don't think that can be done portably.
        * config/tc-mips.c (macro): Use $AT if target register is zero in
        load instruction, which it can be for a floating point load.

        * config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
        with $L is local.
        * config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
        by the section vma.

        * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
        z8k-opc.h, not z8k.h.

        * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
        symbol.

Fri Mar 12 18:33:36 1993  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

Fri Mar 12 12:00:07 1993  Ian Lance Taylor  (ian@cygnus.com)

        * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

        (main): Call strdup instead.

        * configure.in: Handle all 68300 series chips.
        * config/tc-m68k.c: Include config.h.

        (struct loc, struct proc, struct file): Moved to tc-mips.c within
        #ifndef OBJ_ECOFF block, since ECOFF uses different versions.
        * config/tc-mips.c: Rearranged for ECOFF support.  Added
        prototypes for all static functions.  Moved existing minimal
        debugging format support info #ifndef OBJ_ECOFF blocks.
        (macro_build_lui): Eliminated sign_extend argument, because ECOFF
        does not support a non sign extended high 16 bits reloc.  Adjusted

        directory.
        * read.c (s_ignore): Don't declare is_end_of_line.  It's
        redundant, and triggers a VMS gcc compiler bug.

        * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
        current segment as an argument.  (Ignored in all cases but VMS.)
        All callers and definitions changed.

        (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
        (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
        routines.
        (obj_elf_xstab): New routine.
        (obj_elf_set_size): Call as_warn, not fprintf.  Pass desired
        argument to s_ignore.  Put "#if 0" around unused code.
        (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
        Call elf_xstabs for .stabs and .xstabs operators.

        * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".

        * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
        present.

        * configure.in: mips-bsd configuration was missing format spec.
        Should use aout.

        * Makefile.in (Makefile): Depends on configure.in.

        * config/tc-mips.c (append_insn): Don't check for alignment of
        frag in memory; alignment of instructions in section is a separate
        matter.

        * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
        C availability.

        * listing.h: Always provide function declarations, not macros, so
        pcc won't lose.

        * config/obj-aout.c: Use PARAMS macro for declarations.  Remove
        "IGNORE_DEBUG" conditional, since both branches are identical.
        Use S_SET_TYPE, S_GET_TYPE, and S_GET_DESC instead of directly

        section info.
        * write.h (fix_new): Update prototype.

        * tc.h (md_operand, md_convert_frag, tc_headers_hook,
        md_section_align, md_undefined_symbol): Don't provide prototypes
        if these are defined as macros.
        (md_convert_frag) [BFD_ASSEMBLER]: BFD version needs bfd and
        section passed.

        * configure.in: recognise all sparclite variants

Thu Jan  7 05:25:25 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)

        * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
        accidentally changed to use subseg_change where it should have
        been subseg_new.

Tue Jan  5 08:42:16 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)

        * expr.c (operand): If character other than comma or newline is a
        logical end-of-line character, use the newline case.
        From Eric Youngdale:
        (operand): Set X_add_number field for floating-point numbers.
        (operand): Treat zero byte as end-of-operand.

        * configure.in (per-target): Look for with_bfd_assembler option.
        For now, only accept "no", until the merge is done.

        Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
        * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
          config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
        * read.c: Finish conversion to S_* macros in the VMS only
          parts of the program. Add "const" modifier to hex_value.
        * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
          "ifdef OBJ_VMS".
        * expr.c: Add "const" modifier to hex_value.
        * symbols.c: Finish conversion to S_* macros in the VMS only
          parts of the program.  Add "const" modifier to
          md_[long,short]_jump_size. Remove declaration of const_flag
          (which will be declared in obj-vms.h).
        * write.c: Add "const" modifier to md_[long,short]_jump_size.
          Fix arguments to VMS_write_object_file.
        * config-gas.com: New file.  Script for VMS systems to set up the
          configuration to build gas for VMS, and create config.status.
        * make-gas.com: Redone to work with new scheme.
        * obj-vms.c: Patch to fix bug where we were not correctly parsing the
          stabs directives.
        * obj-vms.c:  Define macros COPY_LONG and COPY_SHORT which
          will swap bytes if needed on a big endian system.  Use throughout
          as needed.
        * obj-vms.c (obj_aout_stab):  Add code to generate listing file.
        * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
          types of malformed stabs.  Change parsing algorithm so that we are
          more certain of having all of the information that we need on hand.
        * obj-vms.c (final_forward_reference):  New function, used to help
          resolve the data types of as many struct elements as possible
          when some part of the struct is not fully defined by the compiler.
        * obj-vms.c (VMS_LSYM_Parse):  Correctly handle case of continuation
          stabs directives.
        * obj-vms.c (VMS_write_object_file): Define all vtable psects
          as symbols as well in the object file.  Look for external functions
          that start with "__vt.", and turn them into variables, since the
          g++ compiler is incapable of doing this.
        * tc-vax.c: Add '1' option for backward compatibility with older GCC
          versions.
        * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
        * input-scrub.c (as_where): Fix bug where as would crash if we did not
          have the name of the source file yet.
        * config/ho-vms.h: define HO_VMS, not HO_VAX.

Mon Jan  4 05:17:26 1993  Ken Raeburn  (raeburn@cygnus.com)

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

        * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
        (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

        (section_alignment): Declare only if not BFD_ASSEMBLER.
        (big_section, reg_section, pass1_section, diff_section,
        absent_section, text_section, data_section, bss_section): If
        BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
        mapping to segT enum values.
        (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
        if these are used or defined, if BFD_ASSEMBLER.
        (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
        subseg_new split into two functions.
        (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.

        NO_STDARG.
        (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
        declare with format attribute for -Wformat checking.

Wed Dec 30 10:18:57 1992  Ian Lance Taylor  (ian@cygnus.com)

        * app.c, config/tc-*.c: Don't include read.h, since it is already
        included by as.h.

        * These are based on patches from Minh Tran-le
        <mtranle@paris.intellicorp.com>.
        * configure.in (i[34]86-ibm-aix*): Accept i486 for host.  Use
        obj_format coffbfd and gas_target i386coff for target.
        (i[34]86-*-isc*): New host (uses sysv).
        * config/i386aix.mt: Removed (no longer used).
        * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
        (MINUS_G): Removed.
        (LDFLAGS): Added, defined as -shlib.

        * config/te-sco386.h (LOCAL_LABEL): Don't define.
        (DOT_LABEL_PREFIX): Define.
        * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
        name rather than L0\001.
        * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
        local_bss_counter.
        * symbols.c, symbols.h (local_bss_counter): Removed.
        * write.c (write_object_file): bss no longer uses
        local_bss_counter.  Pass correct data and bss size to
        VMS_write_object_file.
        * config/obj-vms.c (VMS_write_object_file): Accept bss size as
        argument, rather than using local_bss_counter.

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

        H_{SET,GET}_* macros.
        (do_linenos_for): Set lineno size in object_headers.
        (write_object_file): Use H_{SET,GET}_* macros.  Don't bother to
        set s_vaddr here.  If string_byte_count remains 4, set it back to
        0, and only write strings out if there are some.  Call
        fill_section before do_relocs_for and do_linenos_for.
        (obj_coff_section): Handle optional quoted second argument giving
        section characteristics.
        (obj_coff_bss): Added to handle .bss.
        (obj_coff_ident): Added to handle .ident (puts string in .comment
        section).
        (obj_coff_lcomm): Put common symbols in .bss, not .data.
        (fixup_mdeps): Change to segment.  Call frag_wane after
        md_convert_frag.
        (fixup_segment): Explicitly check S_IS_COMMON before making 386
        adjustment (already happened only for common symbols, but this is
        clearer).
        * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
        * config/tc-i386.c (s_bss): Don't use if I386COFF.
        (md_pseudo_table): Ignore .optim and .noopt.
        (tc_coff_sizemachdep): New function.
        * config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3
        compatibility.
        (LOCAL_LABEL): Removed definition.
        (DOT_LABEL_PREFIX): Defined.

        * app.c (app_push): Use memcpy, not bcopy.
        (do_scrub_next_char): For \", return " not '.
        (symbol_chars): Now const.

        * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
        and "0b".  If LOCAL_LABELS_DOLLAR, check for "0$".

        * config/obj-coff.h: Don't use #elif.

        * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
        have it.  (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

Wed Dec 16 12:12:33 1992  Ian Lance Taylor  (ian@cygnus.com)

        * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

        * Changes to support SCO 3.2v4:
        * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
        SEG_BSS, fill with NOP_OPCODE.
        * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
        * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
        using ZERO_BASED_SEGMENTS.
        (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
        never set segment address for SEG_E2 (.bss) and don't write out
        SEG_E2 contents.  Set .init and .fini sections to STYP_TEXT.
        (obj_coff_endef): Don't merge labels or symbols awaiting forward
        definitions, and don't merge tags with non-tags.  Check for .bf
        rather than just checking whether the second character is b and
        the third character is f.
        (obj_coff_val): gcc can generate values which we don't handle
        correctly; discard information for now, since it only affects the
        debugging information.
        (tag_find_or_name): Don't insert tags in the symbol table.
        (yank_symbols): Don't merge labels.
        (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
        already defined.  Fill subsegments with NOP_OPCODE, not 0.  Don't
        set segment address if ZERO_BASED_SEGMENTS.
        (obj_coff_section): Accept and ignore a trailing quoted string, as
        used in AT&T i386 syntax.
        (fixup_segment): Take segment as argument.  On the i386, adjust PC
        relative addends by the segment vaddr.
        * tc-i386.h: Define SUB_SEGMENT_ALIGN.
        * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
        * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

        line_comment_chars, and line_separator_chars.

        * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
        still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
        the register name.

        (fill_section): segment addresses now set in write_object_file.
        (fill_section): Don't set STYP_NOLOAD for .bss section.

        * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
        #elif, since it is not supported by old compilers.
        ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
        couple of expressions in tc-m68k.c.

Mon Sep 28 21:18:24 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)

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

        * tc-m68k.c: Replace "enum m68k_architecture" with "int"

        * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
        .word is < -32768 or > 32767.  The -J flag causes the error to be
        ignored.  This is to catch over-sized switches generated by gcc on
        systems which don't support the broken .word hack.
        as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
        write.c (fixup_segment): check for signed .word overflow if

        messages.c (as_perror): print ": " between the passed in error and
        the strerror, like perror does.

         (fill_section) added rs_machine_dependent case
         (write_object_file) call fixup_mdeps
         (fixup_segment) set fx_subsy to 0.
        obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
         handle m68k.
        tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala

        little endian byte order (used to use endianness of host).

Tue Aug 25 15:50:48 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

        * config/tc-m68k.c (init_table): Now const.  Always include 68851

Wed Aug 19 11:20:59 1992  Ian Lance Taylor  (ian@cygnus.com)

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

Thu Apr  9 05:45:29 1992  Ken Raeburn  (Raeburn@Cygnus.COM)

        * expr.c: If an expression is single comma, then return with

        really strange things with things like fbge,a 

        * as.h: include bfd.h if using many sections
        * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
        local labels didn't work.
        * listing.c (list_symbol_table): don't core dump when there's no
        symbol there.
        * write.c, write.h: call fix_new with the right number of args on

        * as.c: fix typo recently introduced.
        * as.h : Don't include aout/reloc.h - it's not right for COFF!
        * expr.c: Much rewriting, to accomodate MRI syntax for
        expressions. Also easier to read now.
        * listing.c: Put back defuns
        * read.c: modified to accept MRI syntax, put back listing pseudo
        ops so that an assembler built with NO_LISTING ignores list ops
        rather than pukes.
        * write.c, write.h: fixs - only keep a reloc type in a fix if the target
        machine is a SPARC or a 29K.
        * config/obj-aout.c: added s_sect pseudo op
        * config/obj-coffbfd.c: lints, set the filehdr flags right and
        fill in the timestamp.
        * config/obj-coffbfd.h: Since we don't include aout/reloc.h
        anymore, define all the relocs which the tc-<x> bit will use so we
        can translate from them to the coff types.
        * config/tc-a29k.c: reloc_type isn't ane enum any more
        * config/tc-m68k.c: Added NO_RELOC definition.

Fri Feb 21 06:21:07 1992  K. Richard Pixley  (rich@rtl.cygnus.com)

        * read.c, write.c subsegs.c: back out the .bss changes.

        * obj-aout.c: do not include stab.gnu.h if NO_LISTING.

        * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

        * a.out.h: removed.

Fri Feb 21 01:08:48 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)

        * symbols.c (local_label_name): symbols now start with ^A.

        * read.c, subsegs.c, write.c obj-coff.c: added handling of
          `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
          generate these sections.  .align: will use NOP_OPCODE or 0
          for padding. This is just for being nice to the
          disassembler.

        * expr.c (operand): changed to generate local label "\001L0"
          starting with a ^A so that it is recognized as a local label.

        * as.c (perform_an_assembly_pass): zero bss_fix_root, too.

        * tc-i386.c: tc-i386.c: added handling of the following opcodes:
          i/o opcodes - inb, inw, outb and outw.  string manipulation with
          att syntax - scmp, slod, smov, ssca, ssto.

        * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
          to just after .file .

          In obj_crawl_symbol_chain() where it tries to put the external
          symbols apart, with the condition:
            (!S_IS_DEFINED(symbolP) &&
             !S_IS_DEBUG(symbolP) &&
             !SF_GET_STATICS(symbolP))
          it was moving too many symbols out. So I switch it back to the
          condition:
            (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))

          In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
          so that we don't use the F_RELFLG which make the linker complain
          that somebody has stripped the relocation info.

          Also, the AIX ld program require that the relocation table
          is sorted by r_vaddr like the standard ATT assembler does.

          [he also changed the sizeof(struct ...)'s into the coff
          style FOOSZ macros.  I'm not sure this is right, but I can't
          remember why.  xoxorich.]

Fri Feb 21 01:08:48 1992  K. Richard Pixley  (rich@cygnus.com)

        * Makefile.in, configure.in, doc: use the doc.  Build it, install
          it, clean it, etc.

        * read.c: white space and comments only.

        * configure.in: use the new atof-ns32.c for ns32k.

        * write.c: comment change only.

        * tc-m88k.[hc]: pulled in from hack's unfinished work.  These
          aren't yet integrated.

        * tc-i860.[hc]: blew off the dust.  Something must still be done
          about conflicting relocation types.

        * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
          real thing.

        * tc-i960.c, tc-sparc.c: white space and comments only.

        * tc-a29k.h: delete duplicate macro definition.

        * new file atof-ns32k.c copied from hack's last unreleased gas.

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