        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

        * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
        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.

        * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
        (fixup_segment): Add a29k special case; the linker is not prepared

        9 to only keep a space in between identifier characters.

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.

        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.

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

        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.

        (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.

          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

        * 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

          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

          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

          versions.
        * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

        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.

        <mtranle@paris.intellicorp.com>.
        * configure.in (i[34]86-ibm-aix*): Accept i486 for host.  Use

        (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.

        (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).

        (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.)

        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

        (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.

        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.

        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.

Tue Sep 29 10:51:55 1992  Ian Lance Taylor  (ian@cygnus.com)

        * 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)

        * read.c (cons): If NO_RELOC is defined, use it.

        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)

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.

          copyrights to '92, changed some from Cygnus to FSF.

        * 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.
