        * write.c (chain_frchains_together, relax_and_size_seg,
        adjust_reloc_syms, write_relocs): Make third argument PTR, not
        char *, to match definition of bfd_map_over_sections.

        * app.c (do_scrub_next_char): Don't interpret a comment character
        as starting a CPP line directive unless it is a '#' and is the
        very first characters on the line (i.e., do not permit leading
        whitespace).

        * messages.c (identify): Make file argument non-const, to match
        callers.

        * First cut at cleaning up PA instruction parsing.
        * config/tc-hppa.c (pa_get_absolute_expression): Accept pointer to
        insn structure as an argument, and a pointer to a string.  All

        evaluate absolute to get a return value.
        (evaluate_absolute): Addept pointer to insn structure as its
        argument.  All callers changed.

        (CHECK_FIELD): New macro for simple range checking of fields.
        (pa_ip): Delete unused variables.  Use INSERT_FIELD_AND_CONTINUE
        and CHECK_FIELD.  All immediate fields now pass through

        Delete dead code.  Simplify.
        (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
        applied are in range.  Use bfd_put_32 rather than inserting each
        byte of the fixed instrution into the buffer ourselves.

        * write.c (fixup_segment): Delete {SEG,GLOBAL}_DIFF_ALLOWED code,
        it was PA specific and is no longer needed (it's now handled 
        within the PA backend).
        * config/tc-hppa.h (SEG_DIFF_ALLOWED): Delete definition.
        * config/tc-hppa.c (fix_new_hppa): If the subtract symbol for
        a fixup is $global$ change it to NULL as $global$ is really only

        build, but not the dvi or info files.
        * Makefile.in (clean-here): New target; cleans up current
        directory only.

        predefined register table.
        (pa_parse_number): Handle %rp in common register shortcut code.
        Consistently set return value to -1 for an error.  Clean up error
        messages and only print them when "print_errors" is true.  Handle
        empty string case like the HP assembler -- assume a value of
        zero.
 
        * config/ho-hpux.h: Do not include ho-sysv.h.  Instead include
        standard hpux include files to pick up various function decls.

        descriptor information to the BFD symbol.
        (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",
        they are simply markers.  Make R_HPPA_UNWIND_* handling OBJ_ELF
        dependent.
        (pa_build_unwind_subspace): Whole function is OBJ_ELF dependent.
        (pa_entry): Build a R_HPPA_ENTRY relocation when configured for SOM.
        (pa_exit): Likewise, but built a R_HPPA_EXIT relocation.  Do not
        build "end-of-function" symbols for SOM, they are not needed.

        * config/tc-hppa.c (process_exit): Create temporary symbols with
        correct prefixes so they can be eliminated later.

        * config/tc-hppa.c (call_info struct): Delete unused "frame" field.
        (pa_callinfo): Insert framesize into the unwind information as 
        soon as it's available.
        (pa_build_unwind_subspace): Do not insert framesize into the unwind
        information here.

        * Add support for marker type relocations.  These mark areas
        of interest to the linker.  ENTRY/EXIT relocations for SOM are
        an example of marker relocations.
        * write.c (write_relocs): Instead of assuming size of a relocation
        is 4 bytes, pick up the size from relocation itself.
        (fixup_segment): Do not complain that a value is too small for 
        marker relocations.

        stabs section.
        (som_frob_file): New function.  Simply calls adjust_stab_sections
        for each section.

        (macro_build): Ignore macros while searching for insn.  For cases
        i, j, and o, accept the reloc type as an argument rather than
        assuming BFD_RELOC_LO16.  Don't try to convert BFD_RELOC_LO16 to
        BFD_RELOC_MIPS_GPREL.  Added new case a.
        (set_at, load_register, macro): Changed calls to macro_build to
        pass new argument for i, j and o cases.
        (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A.  These require
        special handling when generating SVR4 PIC code.
        (mips_ip, tc_get_register, s_frame): Use macros FP, SP, GP and AT
        rather than hard coded constants.

        BFD_RELOC_MIPS_CALL16.
        (s_option): Set mips_pic based on .option picN.

        text, data, and bss segments with new ones.
        (create_new_subspace): When not using aliases each subspace has a 
        section/segment and subsegments are not needed, so set the subsegment
        to zero. 

        * config/tc-hppa.c (pa_parse_space_stmt): If needed, call
        obj_set_section_attributes to pass space attributes to the

        opcode table already meets these constraints.
        (machine_ip): When handling case 'i' or 'A', make sure that the
        appropriate opcode really exists by looking at the next entry in
        the opcode table.

Mon Oct 25 10:20:31 1993  Ken Raeburn  (raeburn@rover.cygnus.com)

        * doc/Makefile.in (install-info): Use "$<*" so VPATH will find
        as.info* even if they're in $(srcdir) (e.g., for FSF
        distributions).

        * write.c (write_relocs): For relocs that are pc_relative and

        default is to assume production environment, and reject configs
        still being worked on.  Mark Elf configurations (except sparc and
        i386) as developmental.  Deleted cases matching some generic names
        in favor of more specific names.  (E.g., when we get Alpha

        against placing additional object-file dependent code here.  Warn
        against contaminating all of GAS with the internals of tc-hppa.c
        through inclusion of tc-hppa.h.  Delete all forward declarations
        for functions only used within tc-hppa.c, likewise for structures,
        variables, and #defines.  Try to group OBJ_ELF and OBJ_SOM
        conditional code in a few small places.

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

        * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
        field of the fixS structure.  Needed to build unwind
        descriptors correctly.

        * write.c: (fixup_segment): Allow expressions such as
        sym1-sym2+const as long as sym2 is $global$.

        * write.c (adjust_reloc_syms): Provide a hook so that a target
        cpu configuration can reject certain relocation reductions.
        * tc-hppa.h (tc_fix_adjustable): New macro.  Only accept relocations
        which do not involve function symbols.

        * config/tc-hppa.h: Reindent with GNU-indent.  Delete references
        to OBJ_OSFROSE.  Fix typos (OBJ_SOME -> OBJ_SOM).  Delete unused

        (hppa_tc_make_sections): Do not declare elf_get_symtab_map any
        ore.

        * config/tc-hppa.c: (md_section_align): Align all sections to
        a multiple of the section alignment rather than always a
        multiple of 8.

        * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
        bits are zero (eg they specify no relocations), then do not even
        bother adding their entries to thesymextn section.

        undefined symbols.

        * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

        * config/tc-mips.c: Many changes to support simple assembler
        optimization.

        file).
        * config/tc-m88k.c (md_pcrel_from): Corrected return value.
        (omagic): Removed unused variable.

        TARGET_FORMAT.
        (S_IS_LOCAL): Any symbol which includes \001 in the name is local.
        * config/tc-m88k.c, config/tc-m88k.h: Numerous changes to bring
        m88k port up to date, and to add COFF support.

        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.

        * doc/Makefile.in: dvi depends on as.dvi

        dropping a space immediately following an identifier.

        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.)

        * 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

        C availability.

        * listing.h: Always provide function declarations, not macros, so

        * 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)

        * read.c (s_data): Always use "data_section", since it'll map to
        SEG_DATA or SEG_E1 if needed.
        (s_lcomm): Likewise with bss_section.
        (s_fill): Use memset, not bzero.

Thu Dec 31 04:29:27 1992  Ken Raeburn  (raeburn@kr-pc.cygnus.com)

        * read.c: Deleted some code under "#ifdef DONTDEF" that was for
        handling GDB symbol table data.

        * config/obj-aout.h (segment_name): Delete definition.
        (seg_name): Delete declaration.
        * config/obj-bout.h (segment_name, seg_name): Ditto.
        * config/obj-vms.h (segment_name, seg_name): Ditto.
        * config/obj-coff.h (segment_name): Ditto.
        * config/obj-coffbfd.h (segment_name): Ditto.

        BFD_ASSEMBLER.
        (obj_header_append, obj_pre_write_hook): Ditto.
        * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
        (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
        (segment_name) If BFD_ASSEMBLER, look up BFD section name;
        otherwise, use seg_name array.
        (seg_name): Declare only if not BFD_ASSEMBLER.
        (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.

        * as.h (volatile): Don't define if already defined.
        (had_errors, had_warnings): Provide prototypes for ANSI C even if
        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-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
        * 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.
        * config/tc-m88k.c (s_bss): Don't use local_bss_counter.
        * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
        * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
        (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.
        (crawl_symbols): Handle 8 character section name correctly.  Use
        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.

Mon Dec 28 10:32:05 1992  Ken Raeburn  (raeburn@cygnus.com)

        * 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

Sat Dec 12 15:26:34 1992  Ian Lance Taylor  (ian@cygnus.com)

        * listing.c: Call xmalloc, not malloc; don't declare malloc.

        * 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.

        and leave everything else alone.

Fri Dec  4 16:58:42 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

        * Makefile.in (as.new): Don't bother saving as.old.

        * write.c: Conditionalize on OBJ_VMS, not VMS.
        (magic_number_for_object_file): Don't define if OBJ_VMS.

        * config/obj-vms.c: Changes for traditional C.

        z8000 documentation
        * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
        all modified.

Tue Nov 10 09:49:24 1992  Ian Lance Taylor  (ian@cygnus.com)

        * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

        * subsegs.h: add extern to segment_info declaration.

        * read.h: added extern declarations for comment_chars,
        line_comment_chars, and line_separator_chars.
        read.c, app.c: removed definitions of comment_chars,
        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.
        (insert_reg): put REGISTER_PREFIX before register names before
        putting them in the symbol table.

        * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
        (m68k_ip): Don't warn about bignum used as float bit-pattern.

        obj-coffbfd.c (do_relocs_for, write_object_file): set segment
        addresses to reasonable sizes.  New define ZERO_BASED_SEGMENTS can
        be used to set them all to zero as was done before.
        (fill_section): segment addresses now set in write_object_file.
        (fill_section): Don't set STYP_NOLOAD for .bss section.
        (fixup_segment): 386 uses strange common symbol format.

        * 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)

        local labels to start with a .) and set REGISTER_PREFIX to %.
        tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

Fri Sep 25 17:53:43 1992  John Gilmore  (gnu@cygnus.com)

        ignore.

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.

        * 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
        WARN_SIGNED_OVERFLOW_WORD.

         (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
         pseudo ops.

        tc-i960.c (md_ri_to_chars): Always output bout object file in
        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
        data, so that "bc" is available to 68040 cache instructions.
        Added "tt0", "tt1", and 68ec030 variants.
        (md_assemble): Complain if 68000 (only) and 68881 are specified.

        * Makefile.in: defined TARGET_CPU for C code so that it can choose
        one element of a family.

        * tc-m68k.c: use TARGET_CPU to choose default cpu type.

        * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
        so that we can assemble hand-written libgcc code.

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.

Wed Aug 19 09:25:09 1992  Ken Raeburn  (raeburn@cygnus.com)

        * as.h (enum _relax_state): Start off at one, not zero, to better
        catch uninitialized-variable errors.
        (linkrelax): Declare new variable.

        * config/tc-m68k.c (md_pseudo_table): fix the .align thing

        (md_assemble): If no CPU has been set (even if FPU/PMMU
        characteristics have been), default to 68020.  Don't need extra
        quotes around error string.

        * write.c (write_object_file): For b.out format, round up section
        start addresses to match required alignment.

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

        * Makefile.in (install): Install into $(tooldir)/bin, since that's

        * expr.c (operand): if can't work out what sort of operand it is,
        then look through FLT_CHARS for a hint.

Wed Feb 26 18:04:40 1992  K. Richard Pixley  (rich@cygnus.com)

        * Makefile.in, configure.in: removed traces of namesubdir,
          -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
          copyrights to '92, changed some from Cygnus to FSF.

        * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
          -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
          copyrights to '92, changed some from Cygnus to FSF.

Tue Feb 25 14:17:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

        * expr.c: If an expression is single comma, then return with
        SEG_ABSENT rather than an error - since the sparc front end does
        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
        the H8.
        * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
        errors nices

Sat Feb 22 12:26:28 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

        * app.c: MRI compatibility - allow single quote to start a string.
        * 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)

        * Makefile.in: put header files before C source for TAGS; remove
          references to non-existent syscalls.h.

        * 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.

Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)

        * 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.

Mon Feb 17 07:51:06 1992  K. Richard Pixley  (rich at cygnus.com)

        * 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.
