        read from memory, or built then read from memory.

        * elf32-hppa.h: Reformat with gnu-indent and hand fix numerous
        formatting and indention problems gnu-indent can not handle.
        Clarify some comments about relocation types.  Comment basic
        relocation "classes".  Group PARAM declarations together.
        (HPPA_SXT_{NULL, SYMNDX, RG_RELOC}): Make members of a new

Mon Oct 25 16:05:23 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        Fix up warnings from gcc -Wall:
        * coffgen.c (coff_print_symbol): Use %lx and cast n_value to

        * m68k-lynx.mt, i386-lynx.mt (TDEFINES): set

Thu Oct 21 12:16:26 1993  Ken Raeburn  (raeburn@cygnus.com)

        * elfcode.h (FILE_ALIGN): Renamed from EALIGN, to avoid conflict
        with Ultrix header files.

        * som.h (struct som_section_data_struct): Renamed from
        som_section_data to avoid conflict with macro by that name.

        Changes from Jeff Law and Peter Hoogenboom at Utah:

        * elf32-hppa.c (hppa_elf_reloc):  Target register for a 'jump
        in delay slot' optimization in combination with a long call
        stub should always be r31.

        * elf32-hppa.c: (hppa_elf_relocate_insn): To be consistent
        across all relocation types, retrieve instruction addends from
        the relocation entry rather than from the instruction itself.

        * elf32-hppa.c: (hppa_elf_relocate_insn): Fix a relocation
        error that only occurred when the addend of an 'addil' or
        'ldil' was larger than 21 bits and very close to a 2K byte
        boundary.

        * elf32-hppa.c: (hppa_elf_reloc):  Handle the optimization in
        which a jump is placed in the delay slot of a function call.
        The jump was being accomplished via an adjustment to the
        return pointer.  This optimization would break the long call
        stub code, if there was any.

        * elf32-hppa.c: (hppa_elf_build_long_branch_stub): Corrections
        to long branch stubs to avoid use of general register 2.

        * hppa_stubs.h: New stub instructions.

        * elfcode.h: Declare bfd_elf_find_section.

        * som.h (som_section_data): Add new "subspace_index" field.

        * som.c (setup_sections): Save the original SOM subspace index
        in the BFD section associated with that subspace.  
        (som_get_symtab_upper_bound): Implement.
        (som_get_symtab): Implement.
        (som_print_symbol): Implement.
        (som_slurp_string_table): New function to read a string table
        from a SOM object file.
        (som_section_from_subspace_index): New function to return the
        section which corresponds to a SOM subspace index.
        (som_slurp_symbol_table): New function to read the symbol
        table from a SOM object file.
        (som_make_empty_symbol): Check for errors from bfd_zalloc.
        (som_new_section_hook): Initialize subspace_index field to
        -1 instead of 0.

        * som.c (som_object_setup): Fix polarity of test to set HAS_RELOC.
        Set EXEC_P for executables.
        (setup_sections): Correctly identify when a section has
        relocations.
        (log2): New function.
        (setup_sections): Correctly convert between SOM alignments and BFD
        alignments.

        * som.c (setup_sections): Do not set SEC_ALLOC or SEC_LOAD
        for sections which correspond to SOM spaces, doing so confuses
        many utilities.  Set assorted SEC_* flags for SOM subspaces
        which correspond to BFD sections.

        * elf32-hppa.c: (elf32_hppa_backend_fake_sections): The stab
        string table should have sh_type == SHT_STRTAB.  Add
        processing to make it so.

        * elfcode.h: (bfd_section_from_shdr): String tables (other
        than .strtab) were not getting the file offsets recorded, so
        they could not be read from disk.

        * elfcode.h: (elf_make_sections):  Leave the sh_addr field of
        the section header and the vma field of a section at 0 if the
        section is not part of the program execution image. (e.g.,
        .stab)

        * som.[hc]: Change target vector prefix from "hppa" to "som".
        Consistently use obj_som prefix to access fields in backend data
        structures.  Fix all callers/references.

        * som.h: Do not include files only needed for core file reading here.
        Include a.out for both HOST_HPPAHPUX and HOST_HPPABSD.  Delete
        forward structure declarations, they are unnecessary.
        (struct somdata): Delete aux_hdr, and hp_symbol_entry_size fields.
        Change "symbols" to "symtab".  Add "stringtab" and "reloc_filepos"
        fields for future use.  Change obj_som_* macros as appropriate.
        (som_section_data): New structure to keep SOM specific information
        about BFD sections (for future use).

        * som.c: Provide PARAMS declarations for all functions currently

        (struct container): Delete unwanted structure definition.
        (som_object_setup): Add comments.  Use som_mkobject to allocate

        since the other types were really aliases for this type anyways.
        Don't compile this function, since it is static and doesn't appear
        to be used in this file.
        (sym_is_global): Return non-zero for weak symbols.  Abort if
        section pointer is null.

        Only create section symbols for sections that have SEC_ALLOC set,
        and have non-zero size.
        (elf_symbol_from_bfd_symbol): If udata is NULL, and this is a
        section symbol, look up the section in the list of section
        symbols, and set the udata pointer appropriately.  Otherwise, if
        udata is still NULL, fail an assertion, and use 0, instead of
        dropping core.

        consistently and maintainably.
        * nlmcode.h (nlm_object_p):  Expand comments about leaked memory
        to note that the problem is even more serious than just leaked

        (coff_write_symbol): don't zero external auxent; now done in
        coff_swap_aux_out.

Fri Oct 23 13:55:35 1992  Ian Lance Taylor  (ian@cygnus.com)

        * Check fclose return value for errors.

        work out a coff relocation type from a howto's attributes rather
        than using the input r_type field. This fixes PR1677 and allows
        conversion of a.out relocs to coff relocs.

        * coffcode.h (coff_write_relocs): if supplied a relocation
        relative to an absolute symbol, use the right symbol index.

        * reloc.c (bfd_perform_relocation): do a partial link for coff

Fri Oct 23 08:15:56 1992  Ian Lance Taylor  (ian@cygnus.com)

        * changes to support i386-sysv with shared libraries:
        * coffcode.h (sec_to_styp_flags): if TWO_DATA_SECS is defined,

        (make_a_section_from_file): if TWO_DATA_SECS, accept .data2.
        (coff_write_object_contents): force vaddr of .lib to 0; set scnptr
        if section has contents, not just if it is loadable; if
        TWO_DATA_SECS, check for .data2
        (coff_set_section_contents): set vma of .lib section to number of
        .lib sections.

        no-longer-used definitions of L_SET and L_INCR.
        * i386linux.h:  Tweaks to smooth Linux build.

        sco-core.c:  Lint:  Second argument of bfd_seek is always file_ptr.
        Third argument is SEEK_SET or SEEK_CUR.  Result is always 0 or -1.

        * aout-adobe.c, aoutf1.h, aoutx.h, bout.c coff-m68k.c, coff-z8k.c,
        coffcode.h, elf.c, libaout.h, libbfd-in.h, srec.c:  Lint.

        * hosts/i386bsd.h:  Merge changes from Peter Schauer.
        * bout.c (ALIGN):  Rename to ALIGNER, since system header files

        * libaout.h (aout_backend_data): added exec_header_not_counted
        field. For ZMAGIC files only, when text_includes_header is set, by

        section size. For go32, exec header is mapped in but does *not*
        contribute to the size of section.
        * aoutx.h (aout_adjust_sizes_and_vmas): if exec_header_not_counted
        is not set, but ztih is, add the size of the exec header to the

        * aout-target.h (callback): Don't define this function if it won't be
        used.

        * aoutx.h (some_aout_object_p): Restore old aout_data value if this
        type doesn't match.  Don't lose if file sections have already been
        created.

        OMAGIC files.
        (slurp_symbol_table): Use header byte order, not target byte
        order, for reading symbol data.

Thu Oct  8 17:33:39 1992  John Gilmore  (gnu@cygnus.com)

        * configure.in:  Undo some brain damage in the host section.
        * configure.in:  Reformat the target section, test many configs.
        * Makefile.in (make):  Remove obsolete `make make'.
        * aoutx.h (some_aout_object_p):  Make defines line up.

Thu Oct  8 08:52:48 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

        Now a bfd knows whether underscores are normally prepended
        to symbols in its file format.

        * aout-adobe.c, aout-target.h, bout.c, coff-a29k.c, coff-h8300.c,

        * archive.c (_bfd_write_archive_contents):  If read fails (and
        errno!=0) set bfd_error to malformed_archive (since this probably
        indicates a truncated archive), rather than system_call_error.

Mon Oct  5 03:33:39 1992  Mark Eichin  (eichin at tweedledumber.cygnus.com)

        * Makefile.in: added rules for i386bsd.c

        hosts/hppahpux.h: #define NATIVE_HPPAHPUX_COMPILER if not
        __STDC__.
        targets.c (bfd_target_list): if NATIVE_HPPAHPUX_COMPILER, make
        local variable target volatile to avoid mysterious bug in
        HP9000/700 cc.

Sat Sep 26 03:58:49 1992  John Gilmore  (gnu@cygnus.com)

        * config/hppabsd.mh, config.hppahpux.mh:  Remove various bogosity.

        Add comments to remind people to do this.
        Reorder all entries that match manufacturer names, to occur

        * elf.c (section_from_elf_index): Return bfd_abs_section, not 0,
        since we should never have a NULL section.

        tests, set the section to bfd_abs_section.

Fri Sep 25 11:11:57 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

        * coff-z8k.c: getting closer

        * opncls.c (bfd_fdopenr):  Determine whether to fdopen for

        the default):  Because there is no magic number in archives,
        there can be annoying target mis-matches.

Mon Aug 31 10:11:37 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)

        * sparc-opc.c: Rigorously updated to match architecture manual.

        * archive.c (bfd_slurp_bsd_armap): if the symdef_count is too
        large, assume we're using a swapped byte order and fail with
        wrong_format rather than dumping core.

Fri Aug 28 15:38:03 1992  Ken Raeburn  (raeburn@cygnus.com)

        * Renamed opc-sparc.c to sparc-opc.c for systems with short

        lint.

        * coffcode.h (coff_add_missing_symbols): if symbols don't come
        from a coff file (csym is null), dont deref them

        * ieee.c (parse_expression): get the answer right when adding an
        abs+(sec+off), (ieee_generic_stat_arch_elt): call ieee_object_p
        on elts so that filename is filled in.

Thu Aug 20 19:05:48 1992  Ken Raeburn  (raeburn@cygnus.com)

        * bout.c (howto_align_table): New set of relocs, with enough

        * aout-target.h:  Make _bfd_slurp_extended_name_table be
        the default.  Given that we *write* the suckers (for long
        archive member names), we really ought to be able to read them!
        * trad-core.c:  Don't include <machine/reg.h>.  It doesn't
        seem to be needed, and many machines don't have it.

        * cache.c (bfd_cache_delete):  Forward decl with prototype form.
        * archive (normalize):  Add to CONST to match actual usages with
        CONST.

Mon Aug  3 00:35:29 1992  Fred Fish  (fnf@cygnus.com)

        * elf.c (elf_slurp_symbol_table):  Now 2nd arg is where to write
        symbol pointers.  Punt expensive & useless bfd_realloc.  Use
        malloc for raw symbols, and free it before returning.
        (bfd_section_from_shdr):  Do not slurp symbol table until politely
        asked.  Do not even slurp string tables.
        (elf_get_symtab_upper_bound):  Count 'em without reading them.
        (elf_get_symtab):  This is how to politely ask.  Schlurp!

        * archive.c (bsd_write_armap): write the timestamp of the

        the prototype, where they typedef won't be known.
        * libbfd.h:  Updated version.

        * elf.c (bfd_section_from_shdr, elf_slurp_symbol_table):
        Correct misconception that there can be only one symbol table.
        Only call elf_slurp_symbol_table on the full symbol table, not
        the dynamic one which is only a subset of the full one.

        characteristics between (e.g.) a.out formats.

        * section.c (struct sec): New field user_set_vma indicates vma
        field should be heeded, not assumed to be unset.

        * libaout.h (struct aout_backend_data): Various bits of data (not
        all used currently) with characteristics of a.out implementation.
        Important field for now is text_includes_header, indicating that
        the text section starts immediately after the file header, which
        gets mapped in with it.
        (struct aout_data): New fields indicate whether vma has been
        adjusted yet (not yet used), and what magic number will be used in
        the output file (should go away in favor of vma_adjusted).

        from set_section_contents and WRITE_HEADERS.  Sets or adjusts vma
        and size parameters, as well as many header fields, after deciding
        on magic number for output file.  Checks to ensure that this
        adjustment has only been done once.
        (set_section_contents): Call adjust_sizes_and_vmas instead of
        doing much of the work here.

        * aout-target.h (MY_make_debug_symbol, MY_backend_data): Provide
        default (null) values of these fields.
        * aoutf1.h (sunos4_write_object_contents): Don't override a_text

        * config/ncr3000.mh (INSTALL, RANLIB):  Don't use /usr/ucb/install,
        it's broken on ncr 3000's.  Use simple "true" for RANLIB.

        to find string sections that BFD hides from it.

        archvie header string counts the endian way, this heuristic sees
        how big an archive string to read by trying it one way and if the
        string table is unreasonably big, trying it the other. *FIXME*.

Wed Dec 18 17:17:59 1991  Stu Grossman  (grossman at cygnus.com)

        * bfd-in.h, libaout.h:  ANSIfy enums.

Wed Dec 18 16:12:25 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

        * archive.c (normalize): created version for VMS which removes the
        VMS directory crap from the front and end of a filename, eg turn
        [-.foo]bar.obj;123 into bar.obj
        (bfd_construct_extended_name_table): now writes index into an
        extended name table in decimal - the same base used to read an
        extended name table.

Wed Dec 18 14:40:39 1991  Per Bothner  (bothner at cygnus.com)

        * aout-encap.c:  Fix to use aout-target.h.
        * aoutf1.h:  Use standard MY_object_p and MY_callback
        in aout-target.h.  Remove target-specific versions.
        * host-aout.c:  Re-write to use aout-target.h.
        * gen-aout.c:  New files use with host-aout.c to generate
        host-specific a.out-related parameters.
        * Makefile.in:  host-aout.o depends on aout-params.h, which is
        generated by gen-aout.
        * aout-target.h:  Make a little more flexible.
        * libaout.h, aout-target.h:  Removed WORK_OUT_FILE_POSTIONS
        macro.  Instead, inline it in aout-target.h.
        * newsos3.c:  Define N_SHARED_LIB(x) as 0 to avoid
        a gcc -Wall warning.
        * archive.c:  Add missing commas in DEFUN macro (2 places).
        * elf.c, coffcode.h, aoutf1.h:  Use ANSI functions instead of
        Berkeley ones, now that libiberty has them:
        bcopy->memcpy, bzero->memset, bcmp->memcmp.
        * aoutx.h:  Various touch-ups:  Re-formatting, fix a cast,
        remove unused variable.

Tue Dec 17 19:48:59 1991  Fred Fish  (fnf at cygnus.com)

        * elf.c (elf_core_file_matches_executable_p):  Enclose corename
        and execname inside HAVE_PROCFS ifdef since they are unused
        when it is not defined.

Mon Dec 16 12:00:10 1991  Fred Fish  (fnf at cygnus.com)

        * elf.c:  Flag all sections as either code or data.  We can't
        be sure what they are anyway, since ELF doesn't fit the
        traditional model of text+data+bss very well.  Add new local
        function elf_read() to simplify code.  Record entry point in
        the bfd structure.

Thu Dec 12 21:01:22 1991  John Gilmore  (gnu at cygnus.com)

        * hosts/h-*.h:  Configure fopen using ../include/fopen-*.h
        rather than N copies of the same lines.

Wed Dec 11 16:39:45 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

        * cpu-h8300.c: disassemble branch displacements correctly
        * coff-h8300.c: put reloc offsets out in 32bits

        * makefile.dos, configdj.bat: New files from DJ
        * cache.c: fopen with new macros is needed for DOS.
        * ieee.c: environ renamed to envi to stop an include file
        conflict.
        * opncls.c, coff-rs6000.c: more fopens with macros.

Tue Dec 10 04:07:24 1991  K. Richard Pixley  (rich at rtl.cygnus.com)

        * Makefile.in: infodir belongs in datadir.

Sat Dec  7 16:39:23 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

         * Makefile.in: fix where docdir lives

         * aoutx.h, archive.c, archures.c, bfd.c, cache.c, coff-m88k.c,
         coffcode.h, core.c, ctor.c, elf.c, format.c, ieee.c, init.c,
         libbfd.c, libbfd.h, libcoff.h, opncls.c, reloc.c, section.c,
         srec.c, syms.c, targets.c : all new documentation and lint
         removal.


Sat Dec  7 07:22:09 1991  John Gilmore  (gnu at cygnus.com)

        * coffcode.h, srec.c:  Lint.

Fri Dec  6 22:58:48 1991  K. Richard Pixley  (rich at rtl.cygnus.com)

        * Makefile.in: install using INSTALL_DATA, added standards.text
          support.

        * configure.in: mark directory as target dependent.  configure
          nows works in objdir always so make file existence checks
          against ${srcdir}.

Thu Dec  5 22:46:19 1991  K. Richard Pixley  (rich at rtl.cygnus.com)

        * Makefile.in: idestdir and ddestdir go away.  Added copyrights
          and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
          and mandir now keyed off datadir by default.

Wed Dec  4 10:14:17 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

        * aoutf1.h (sunos_<size>_object_p, sunos4_callback): moved the
        computation of arch and machine type so it's worked out before
        some_aout_object_p is called.
        * aoutx.h: (some_aout_object_p): don't set arch and mach to
        unknown.
        * archures.c: add extra field 'section_align_power' to hold
        default section alignment in object files.
        * cpu-a29k.c, cpu-h8300.c, cpu-i386.c, cpu-i960.c, cpu-m68k.c,
        cpu-m88k.c, cpu-mips.c, cpu-rs6000.c, cpu-sparc.c, cpu-vax.c:
        initialize the new field.
        * bout.c (b_out_callback): replace the text size, since aout
        fries them.
        * aoutx.h: Documentation in the new style

Wed Dec  4 02:00:30 1991  John Gilmore  (gnu at cygnus.com)

        * bfd.c (bfd_get_mtime):  Don't cache mtime any more; only
        use the saved value if mtime_set is already set (intended
        for archive files, though apparently not used yet).

Tue Dec  3 22:54:50 1991  John Gilmore  (gnu at cygnus.com)

        * targets.c:  Revise comments about how to configure the target
        vector, to match reality.  Remove mention of obsolete methods.
        Remove long lists of capitalized macros that turn into the same
        thing in lowercase.  Normal vector simply lists all known
        lowercase xvec names; all other cases are handled by SELECT_VECS.

        * config/mt-i386-coff:  Set DEFAULT_VECTOR to real identifier,
        not macro name.

        * config/mt-i960-{coff,bout}:  Use SELECT_VECS to make a short
        list of supported targets.

Tue Dec  3 14:06:15 1991  Per Bothner  (bothner at cygnus.com)

        * archive.c (bsd_write_armap):  The pad byte sometimes added to
        the string table in a __.SYMDEF member is now
        counted as part of the size of the string table.
        This is compatible with the old ranlib, as well as Sun's.

Tue Dec  3 10:53:30 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

        * srec.c: Rewrote to fix many bugs; now gets the record type
        right, doesn't choke on input, sets the start address in an S9 and
        fills in the filename on an S0.

Sat Nov 30 21:19:15 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

        * cpu-h8300.c: Add support for MEMIND addressing mode

        * coff-a29k.c: defined RELOC_PROCESSING to take the #ifdef out of
        coffcode.h
        * coffcode.h: use the new macro if available

        * elf.c (elf_corefile_note): cast malloc to avoid warning.
        * Makefile.in: Fixed dependencies due to file rename

        * aout-encap.c, aoutf1.h, aoutx.h, archive.c, bout.c, coff-a29k.c,
        coff-h8300.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
        coff-mips.c, coff-rs6000.c, cpu-h300.c, elf.c, i386aout.c,
        newos3.c, stab-syms.c, syms.c: All these files have had their
        #includes altered to point to the new places.

Fri Nov 29 20:04:49 1991  Fred Fish  (fnf at cygnus.com)

        * config/mh-i386v4, config/mh-i386-elf, hosts/h-i386v4.h:  New files.

        * configure.in:  Add vendor "ncr" as supported per-target vendor.
        Add svr4 case for i386 per-host case.

        * elf.c (elf_object_p, elf_core_file_p):  Add missing "break" to
        ELFDATA2LSB cases.

Fri Nov 29 12:16:51 1991  Per Bothner  (bothner at cygnus.com)

        * syms.c (bfd_decode_symclass):  Return 'A'
        for symbols that are both absolute and global.
        * archive.c (bfd_special_undocumented_glue):  Return NULL
        if bfd_ar_hdr_from_filesystem returns NULL.

Tue Nov 26 09:10:55 1991  Steve Chamberlain  (sac at cygnus.com)

        * Makefile.in: added coff-h8300
        * configure.in: now h8 is a coff target
        * cpu-h8300.c: fix various disassembly problems
        * libcoff.h: took out some code which has been #0ed for a long
        time.
        * targets.c: added h8 coff
        * coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c
        added new macro RTYPE2HOWTO to take a load of #ifdefs out of
        coffcode.h
        * coffcode.h: Started to change the way machine dependencies are
        handled, from the nest of #ifdefs to macros defined in the
        including coff-<foo>.c

Fri Nov 22 08:11:42 1991  John Gilmore  (gnu at cygnus.com)

        * aoutx.h (some_aout_object_p):  Set the `executable' bit
        if the entry point is contained in the text segment, even if the
        text segment is at location 0.

        * coff-mips.c, coffcode.h:  Peter Schauer's patch to kludge in
        nonstandard MIPS sections (.rdata, .sdata, etc).

        * aoutx.h, bfd.c, coffcode.h, ieee.c, oasys.c, targets.c: CONST lint.
        * libbfd-in.h, libbfd.h, aoutx.h, coffcode.h, elf.c, libaout.h:
        Rename ALIGN to BFD_ALIGN to avoid conflict with BSD <sys/param.h>.
        * libbfd.c:  Lint.
        * host-aout.c, trad-core.c:  Fix write_armap prototypes.  Lint.

Thu Nov 21 19:56:40 1991  Per Bothner  (bothner at cygnus.com)

        * stab-syms.c, syms.c:  Moved bfd_stab_name() and bfd_stab_names[]
        from syms.c to new file stab-syms.c.  Also, since GNU extended
        type codes such as N_SETT are no longer in ../include/stab.def,
        include them manually.
        * stab-syms.c, aoutx.h: Renamed bfd_stab_name() and
        bfd_stab_names[] to aout_stab_name() and aout_stab_names[].
        * libaout.h: Added prototype for aout_stab_name().
        * Makefile.in:  Update Makefile for new stab-syms.[co].

Thu Nov 21 11:50:49 1991  John Gilmore  (gnu at cygnus.com)

        * libaout.h (WORK_OUT_FILE_POSITIONS):  One more try at this
        rather complicated seeming problem.  Eliminate LOGICAL_ versions,
        just make N_XXX work by excluding the header from the text segment.
        * aoutx.h:  Fix comments to match.

Tue Nov 19 18:49:01 1991  Per Bothner  (bothner at cygnus.com)

        * libaout.h (WORK_OUT_FILE_POSITIONS):  Use new LOGICAL_TXTADDR,
        LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
        for the "logical" text segment (i.e. never consider the exec
        header to be part of the text segment).  This change is
        needed for consistency with various other parts of bfd and ld.
        * aoutx.h (NAME(aout,soe_aout_object_p)):  Fix comment,
        and move calculation of obj_textsec(abfd)->size to libaout.h.
        * bfd-in.h:  Removed bogus ';'.

        * Makefile.in:  Add MINIMIZE flag to select lean
        or bloated target_vector.
        * targets.c:  Use new MINIMIZE macro, and add trad_core if needed.
        * newsos3.c:  Fixes to ../include/aout64.h remove need
        for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.

Mon Nov 18 12:00:59 1991  Per Bothner  (bothner at cygnus.com)

        * aout-target.h, aoutf1.h, newsos3.c:  Make aout-target.h
        handle both little and big-endian targets, with little
        the default unless TARGET_IS_BIG_ENDIAN_P is defined.
        * host-aout.c:  Add FIXME note.

Sun Nov 17 13:29:39 1991  Per Bothner  (bothner at cygnus.com)

        * targets.c:  Make the default target_vector contain
        just &DEFAULT_VECTOR.  This makes executables a lot smaller.
        Old behavior can be gotten by defining ALL_TARGETS.
        * aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
        Factored out common code into new file aout-target.h.
        Saves a lot of duplicate code for a.out variants.

Fri Nov 15 13:00:43 1991  Per Bothner  (bothner at cygnus.com)

        Get 'make headers' to work when configured with +subdirs.
        * Makefile.in: Add $(subdir) to docdir path.
        * doc/Makefile.in (protos): Add $(srcdir) prefix
        to name of sed scripts.

Thu Nov 14 19:49:10 1991  Per Bothner  (bothner at cygnus.com)

        * aoutx.h (NAME(aout,print_symbol)):  Fix thinko.
        * syms.c (bfd_stab_names):  Turn on new GNU_EXTRA_STABS macro
        to include names of N_SETT etc.

Thu Nov 14 19:11:13 1991  Fred Fish  (fnf at cygnus.com)

        * elf.c:  Add minimal support for ELF symbol tables.  Generates
        canonical bfd symbol tables from ELF symbol tables.  Change the
        name of some functions from bfd_<name> to elf_<name>.

        * syms.c:  Trivial fix to comment to remove a redundant "to".

Wed Nov 13 17:02:01 1991  John Gilmore  (gnu at cygnus.com)

        * coff-{i386,m68k,m88k}.c:  Change name of file format to standard
        form that GDB recognizes as COFF.

Wed Nov 13 09:09:41 1991  Steve Chamberlain  (sac at cygnus.com)

        * ieee.c (ieee_object_p):  cast NULL correctly.
        * configure.in: added harris host

        * coff-a29k.c: Lots of changes, most from David Wood.

Tue Nov 12 07:21:41 1991  John Gilmore  (gnu at cygnus.com)

        * coff-m88k.c (coff_write_armap):  Just #undef it.

Mon Nov 11 20:30:18 1991  Steve Chamberlain  (sac at cygnus.com)

        * Makefile.in: standardize on MINUS_G to disable debugging
        * coff-m88k.c: create coff armaps instead of bsd ones.
        * opncls.c (bfd_close_all_done), (bfd_close): Mask out random bits
        when calling chmod.

Mon Nov 11 19:07:32 1991  Fred Fish  (fnf at cygnus.com)

        * elf.c:  Additions to support ELF format core files.
        * config/mh-amix:  Add -DHAVE_PROCFS to HDEFINES, since host
        has support for /proc (all the include files in particular).

Mon Nov 11 18:36:47 1991  Per Bothner  (bothner at cygnus.com)

        * aoutx.h (NAME(aout,find_nearest_line)):  Handle the case
        of two N_SO stabs, one for directory, and one for filename.

        * bfd-in.h (print_vma):  Factor out duplicate definition.

        Exit a little more gracefully when malloc returns NULL.
        * libbfd.c: New function bfd_xmalloc (malloc wrapper).
        * opncls.c, syms.c, bout.c, aoutx.h:  Replace malloc by bfd_xmalloc.
        * libbfd.h: Rre-generated due to libbfd.c update.

Sat Nov  9 13:45:01 1991  Fred Fish  (fnf at cygnus.com)

        * config/mt-m68k-elf:  Define DEFAULT_VECTOR as elf_big_vec.

        * elf.c (elf_object_p):  Don't try to create a bfd section for
        the first ELF section header.  It is just a placeholder.

Sat Nov  9 03:04:26 1991  John Gilmore  (gnu at cygnus.com)

        * coff-rs6000.c, config/mh-rs6000:  Make it work on archive and
        core files, when compiling native.
        * hosts/h-rs6000.h:  Define FASCIST_FDOPEN for bfd_fdopenr.

        FIXME:  The aoutf1.h change below needs to be reversed back
        to the way it was.

Thu Nov  7 11:03:55 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

        * coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
        manipulation of lnno fields in lineno structs in a coff-<f>.h
        independent way. Override it in coff-<f>.h to your favourite
        number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
        (coff_swap_lineno_out): modified to use the new macros.

Mon Nov  4 11:38:33 1991  Steve Chamberlain  (sac at cygnus.com)

        * aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
        unknown arch when the magic number doesn't specify the
        architecture, since some OSs (eg old sun3s) don't set the number, and
        020 is probably the right answer anyway.

Sun Nov  3 12:07:08 1991  Per Bothner  (bothner at cygnus.com)

        * hosts/h-news.h, hosts/h-rtbsd.h:
        Get rid of MISSING_VFPRINTF, since libiberty provides one.
        * bfd-in.h (bfd_print_symbol_type_hopw enum):   Add new option
        bfd_print_symbol_nm, for use by nm.
        * aoutx.h (NAME(aout,print_symbol)):  Add code for new
        bfd_print_symbol_nm option, to print in nm format.
        * coffcode.h (coff_print_symbol), ieee.c (ieee_print_symbol)
        oasys.c (oasys_print_symbol):  Provide stub implementations
        for bfd_print_symbol_nm.
        * syms.c:  New function bfd_decode_symclass, used by nm printer.
        New function bfd_stab_name to look up string name of stab code.

Sat Nov  2 14:26:03 1991  Steve Chamberlain  (steve at cygnus.com)

        * Makefile.in: Added ctor.c
        * archures.c (bfd_default_arch_struct) added
        bfd_default_reloc_type_lookup.
        * coffcode.h: removed a load of #if 0ed code.
        (coff_compute_file_section_positions): now works out the section
        alignment and size correctly in all cases.
        (coff_get_symtab): looks for constructor symbols and calls the
        right function when they're found. (coff_canonicalize_reloc):
        knows when a section is full of constructors and does the right
        thing.
        * cpu-m88k.c: Added default_reloc_type lookup to the architecture
        description.
        * libbfd-in.h: (bfd_default_reloc_type_lookup) defun  added.
        * libcoff.h: removed #if 0ed code
        * reloc.c: (bfd_reloc_code_real_type) added BFD_RELOC_CTOR for
        arch independent constructor relocation type.
        (bfd_reloc_type_lookup): removed the comment "this will go away"
        since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
        reloc which is used when BFD_RELOC_CTOR falls through to give a
        default 32bit reloc for constructors.
        (bfd_default_reloc_type_lookup): added.
        * aoutf1.h: fixed SEGMENT_SIZE typo.

Thu Oct 31 18:23:06 1991  John Gilmore  (gnu at cygnus.com)

        * coff-rs6000.c:  Change name to "aixcoff-rs6000", to avoid
        matching prefix "coff".
        * coffcode.h (coff_swap_aux_in, coff_swap_aux_out):  Handle
        rs/6000 csect records.

Sun Oct 27 16:56:58 1991  Steve Chamberlain  (steve at cygnus.com)

        * configure.in: add motorola delta88 cases
        * libbfd.h, libbfd-in.h, archive.c, ieee.c, elf.c, srec.c: fix
        write_armap prototype
        * libbfd.c: add doc on bfd_write_bigendian_4byte_int

Fri Oct 25 02:48:19 1991  John Gilmore  (gnu at cygnus.com)

        * Rename COFF-related files in `coff-ARCH.c' form.
        coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
        coff-mips.c, coff-rs6000.c to be exact.

        * Makefile.in:  Only supply TARGET_DEFAULTS to targets.c, reducing
        make output clutter.
        * config/mt-*:  Ditto.

Thu Oct 24 22:40:07 1991  John Gilmore  (gnu at cygnus.com)

        RS/6000 support, by Metin G. Ozisik, Mimi Phûông-Thåo Võ, and
        John Gilmore.  Archive support from Damon A. Permezel.

        * configure.in:  Add rs6000 case.
        * targets.c:  Add rs6000 vector.
        * archures.c:  Add rs6000, fix comment on romp.
        * bfd-in.h (enum bfd_error):  Add no_debug_section error.
        * libcoff-in.h (struct coff_tdata):  Remove unused string_table.
        * bfd.c (bfd_errmsgs):  Add no_debug_section error message.
        * section.c (bfd_make_section):  Return NULL on attempt to create
        a section twice.
        * coffcode.h (bfd_swap_reloc_in):  Handle r_type and r_size.
        (bfd_swap_aouthdr_in):  Handle lots more members.
        (make_a_section_from_file):  If section has already been seen,
        just return false rather than overwriting it.
        (coff_real_object_p):  Understand incoming magic numbers.
        (coff_set_flags):  Understand outgoing magic numbers.
        (coff_compute_section_file_positions):  outgoing aouthdr magic #.
        (build_debug_section):  Add fn for reading debug string section.

        existing section before making one.
        * cpu-rs6000.c:  New file.
        * rs6000coff.c:  New file.

Thu Oct 24 02:03:24 1991  Fred Fish  (fnf at cygnus.com)

        * elf.c: Add partial support for ELF format corefiles. Still needs
        support for extracting registers from corefiles.

        * config/t-m68k-elf:  Set DEFAULT_VECTOR to elf_big_vec.

        * config/{h-amix,h-dgux,h-irix3,h-ultra3}: For systems where
        RANLIB is defined as echo, send the output to /dev/null to help
        reduce clutter in the output from doing a make.

Mon Oct 21 17:48:48 1991  John Gilmore  (gnu at cygnus.com)

        * hosts/h-vaxult.h:  Remove malloc/free decls covered in stdlib.h.
        Fix HOST_PAGE_SIZE and HOST_SEGMENT_SIZE.  From David Taylor.

Mon Oct 21 09:34:11 1991  Steve Chamberlain  (steve at rtl.cygnus.com)

        * coffcode.h (coff_compute_section_file_positions): make it pad
        section size out if there are alignment restrictions so that the
        image will be ok on a system where section positions are worked
        out by accumulating sizes rather than from the section headers.
        * targets.c (proto write_armap). Changed orl_count to unsigned.
        * opncls.c (bfd_close_all_done). Added so that generative
        programs like gas can close a bfd without causing bfd confusion.
        * libbfd.h (changed becuase of protos)
        * amdcoff.c: messed with the way that jmp displacements are
        calcualated. This may not yet be totally correct.
        * archive.c (coff_write_armap): rewrote the way that ranlibs are
        written out.
        * coffcode.h (fixup_symbol_value): now doesn't core dump if a non
        abs symbol has no section (like a register symbol).
        (coff_write_symbol) now zeros auxent before filling it up to help
        with sensitive applications.
        * libbfd.c (bfd_write_bigendian_4byte_int): added.

Wed Oct 16 22:58:45 1991  John Gilmore  (gnu at cygnus.com)

        * bfd.c:  Make sure we don't get a macro strerror().
        * opncls.c (bfd_fdopenr):  If FASCIST_FDOPEN, use "r", not "r+".
        * trad-core.c (trad_unix_core_file_failing_command):  Suppress
        attempt to recover command, ifdef NO_CORE_COMMAND.
        * hosts/h-tahoe.h:  Add FASCIST_FDOPEN and NO_CORE_COMMAND;
        revamp HOST_*, etc.
        * hosts/h-i386v.h:  Use <utime.h>, not <sys/utime.h>, unlike POSIX.

Wed Oct 16 12:43:49 1991  Per Bothner  (bothner at cygnus.com)

        * archive.c (bsd_write_argmap): The size of the ranlib structures
        should not include the size field itself.
        * aoutx.h, libaout.h (NAME(aout, sizeof_headers)):  Use
        adata(abfd)->exec_bytes_size field instead of constant macro,
        because aoutx.h compiles to a simple .o file shared by
        all 32-bits a.out targets.

Wed Oct 16 11:11:05 1991  John Gilmore  (gnu at cygnus.com)

        * configure.in:  Allow i386-sco-sysv.
        * bout.c:  Remove unused i960_align; lint dummy core file handlers.
        * cpu-h8300.c:  lint.

        * host-aout.c:  New strategy.  We use common code, include files,
        and data structures to handle the file, but set a few parameters
        from the host's config file (page size, text start addr, etc).
        * libaout.h:  Define HP BSD machine types.
        * aoutf1.h:  Handle reading a.outs with these types.

        * trad-core.c:  Pass the u.u_ar0 value as the negative of the
        virtual-memory-address of the .reg section.  We can't just make a
        section for "all the regs and nothing else" because only GDB knows
        exactly where the regs are (scattered around the upage and stack).
        Clean up memory allocation.  Remove big- and little-endian
        vectors, replace with single vector; this only runs on the host,
        in host byte order.  Replace byteswap routines with aborts in case
        anyone calls them.
        * targets.c:  There's only one trad_core_vec now.
        * aoutf1.h (sunos_core_file_p):  VMA of .reg* now needs to be 0.

Tue Oct 15 08:29:03 1991  John Gilmore  (gnu at cygnus.com)

        * hosts/h-amix.h (free):  Fix prototype.

        * aoutx.h:  Don't use NULL as an integer, for braindead systems
        that declare it as (void *)0.  (From Peter Schauer.)

Mon Oct 14 17:20:47 1991  Per Bothner  (bothner at cygnus.com)

        * opncls.c (bfd_fdopenr):  Add parentheses to avoid reported
        problem with bad Ultrix system headers.
        * aoutx.h (NAME(aout,set_section_contents)):  Try to handle the
        various kinds of alignments for the various kinds of
        magic numbers.

Mon Oct 14 14:23:10 1991  John Gilmore  (gnu at cygnus.com)

        * doc/Makefile:  Don't assume . is on the path (from James Clark).

Fri Oct 11 22:45:14 1991  John Gilmore  (gnu at cygnus.com)

        * Makefile.in:  Avoid Sun Make VPATH bugs.
        * targets.c:  Declare trad_core vectors extern.

Fri Oct 11 13:03:02 1991  Per Bothner  (bothner at cygnus.com)

        * coffcode.h: Moved ALIGN macro to libbfd.h. Removed i960_align.
        * libbfd.h: Moved ALIGN macro here.
        * bout.c (b_out_callback): Replace i960_align by align_power.

        * libaout.h (struct aoutdata):  Added fields page_size,
        segment_size and exec_bytes_size.  These help generic code
        (in aoutx.h and libaout.h) to figure out where to align
        the various segments in a demand paged file.
        * libaout.h (WRITE_HEADER):  Use new (struct aoutdata) fields
        to decide if the exec header counts in a_text (text segment size).
        Also, assume D_PAGED flag is set; don't set it here.
        * bout.c (b_out_callback): Add initialization of
        adata fields page_size, segment_size, and exec_bytes_size.
        * host-aout.c (NAME(host_aout, callback) and
        NAME(host_aout,mkobject): Ditto.
        * i386aout.c (aout386_callback) and new aout386_mkobject): Ditto.
        * newos3.c (newsos3_callback) and new newsos_mkobject): Ditto.
        * aoutf1.c (sunos4_callback) and new sunos_mkobject): Ditto.
        * aoutx.h (NAME(aout,some_aout_object_p)): Don't subtract
        EXEC_BYTES_SIZE from the a_test size; this is only appropriate
        for some systems (mainly sunos), so do it in the callback instead.
        Same routine: Add stuff to the THIS_IS_ONLY_DOCUMENTATION comment.
        * aoutx.h (NAME(aout,set_section_contents): Change the way
        filepos and size of sections are carried out to support
        older styles of demand paged executables.


Fri Oct 11 12:33:36 1991  Steve Chamberlain  (steve at cygnus.com)

        * bfd-in.h: Added more macros to COFF_SWAP_TABLE.
        * bfd.c: Added macros to enable gas to swap coff records.
        * coffcode.h: Make the coff_swap_*_out routines return the number
        of bytes swapped, and cleaned up their prototypes.
        * configure.in: Added ebmon/coff support
        * ecoff.c: Changed null definitions of coff_swap_*_out to conform
        to new prototypes
        * targets.c: Added new entry points for coff swapping

Fri Oct 11 03:01:52 1991  John Gilmore  (gnu at cygnus.com)

        Restructure configuration scheme for bfd, binutils, ld.

        * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
        * configure.in:  Revise to symlink sysdep.h to hosts/h-xxx.h.
        Change some config names to match other dirs.
        * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
        get defined first.
        * Makefile.in:  Use -I. to get sysdep.h.  Remove refs to
        ../include/sysdep.h.
        * cpu-i960.c:  Strncmp needed a length arg.
        * ecoff.c:  Don't ever call trad_unix_core_file_p from here.
        * i386aout.c:  Remove dead N_TXTOFF override.
        * trad-core.c:  Don't disable the whole file if SUN4_SYS.
        * config/:  Rename some config files to match up h-*.h names.
        Remove all the HOST_SYS definitions from the config files.
        * hosts/h-amix.h, h-i386v.h:  Define POSIX_UTIME, not USG.
        * hosts/h-hp9000.h:  Remove USG comment.
        * hosts/h-rs6000.h:  Include <stdlib.h> for malloc.
        * hosts/h-news.h, h-sparc-64.h:  New config files that had
        previously been kludged in the <sysdep.h> file.

Thu Oct 10 17:54:08 1991  John Gilmore  (gnu at cygnus.com)

        * config/*:  trad-core support is HOST dependent, not target
        dependent.  Target config files only set DEFAULT_VECTOR and/or
        other vector elements.  Exception:  when host-aout.c is in use,
        in which case we're forced to assume we're native (hp, vax,
        tahoe).  Rename XDEPFILES to HDEPFILES.
        * Makefile.in:  Rename XDEPFILES.
        * config/h-sun*:  Don't force static linking.
        * trad-core.c:  Document how to use it nowadays.
        * i386aout.c, newsos3.c:  Clean up.
        * i386coff.c:  Allow 386 coff files to be used as core files too
        (for reading core files from embedded systems).

Tue Oct  8 15:30:39 1991  John Gilmore  (gnu at cygnus.com)

        * Add i386aout.c for a.out support on the i386.

Tue Oct  8 12:18:54 1991  Roland H. Pesch  (pesch at cygnus.com)

        * reloc.c, section.c, syms.c, targets.c: correct info-node
        structure in *doc* comments.
        doc/Makefile: stop hiding complaints from makeinfo.

Sun Oct  6 19:10:06 1991  John Gilmore  (gnu at cygnus.com)

        * aoutx.h (...some_aout_object_p):  Take a third parameter,
        the internal_exec struct, and avoid ever looking at an
        external_exec.  All callers changed to read the entire
        external_exec struct, swap and check its magic number,
        swap in the whole structure, and pass the swapped-in version to
        some_aout_object_p.
        * bout.c:  Bring into modern era.  Use single _object_p routine
        for big- aand little-endian.  Provide internal and external
        exec header structs.  Use separate swap-in and swap-out routines.

        * libaout.h:  Move struct internal_exec from ../include/aout64.h
        to here.  Add obj_symbol_entry_size to struct aoutdata.
        * aoutx.h (...some_aout_object_p):  Set obj_symbol_entry_size.

        * ../include/aout64.h:  Change EXTERNAL_LIST_SIZE to
        EXTERNAL_NLIST_SIZE.  Callers changed.

Fri Oct  4 18:18:46 1991  John Gilmore  (gnu at cygnus.com)

        * bfd.c:  Remove strerror() to libiberty.

        * elf.c:  Remove elf_set_section_contents, use generic one.  Lint.
        * libbfd-in.h, libbfd.c:  Add bfd_generic_set_section_contents.
        * libbfd.c (bfd_generic_{get,set}_section_contents):  Check that
        last byte of transfer, not first byte, is within the section.

        * host-aout.c:  Remove `BSD' archive support.  Lint.

        * archures.c: Rename `struct bfd_arch_info_struct' to `struct
        bfd_arch_info'.  Rename `typedef bfd_arch_info_struct_type' to
        `bfd_arch_info_type'.  All uses changed.
        * reloc.c:  Rename `bfd_reloc_status_enum_type' to
        `bfd_reloc_status_type'.  Rename `bfd_reloc_code_enum_real_type'
        to `bfd_reloc_code_real_type'.  (This seems to be a misnomer,
        it needs a better name.)  All uses changed.
        * targets.c:  Rename `enum target_flavour_enum' to `enum
        target_flavour', and remove the `_enum' from all of the enum
        values themselves.  All uses changed.

        * configure.in, config/h-i386mach:  i386 mach host.
        * config/t-i386-aout:  Use host-aout.c.

        * trad-core.c:  Give it its own xvec's to make it independent
        of other file formats.
        * ecoff.c, host-aout.c:  Remove refs to trad-core.
        * config/t-dec3100, t-hp300bsd, t-tahoe, t-vax:  Define TRAD_CORE.
        * targets.c:  #ifdef TRAD_CORE, include it in the vector.

Fri Oct  4 17:38:03 1991  Steve Chamberlain  (steve at cygnus.com)

        * reloc.c: Extended NEWHOWTO macro
        * ieee.c: Changed the way 8bit pcrel is done
        * cpu-h8300.c: got the registers in the right order

Thu Oct  3 19:39:55 1991  John Gilmore  (gnu at cygnus.com)

        * bfd-in.h:  enum boolean => enum bfd_boolean for SVR4.  Gumby's
        prediction is vindicated!

        * bfd-in.h, libbfd-in.h, doc/Makefile, doc/tolibbfd, doc/intobfd:
        Remove refs to howto.c, since Steve forgot.

Thu Oct  3 07:49:21 1991  Steve Chamberlain  (steve at cygnus.com)

        * elf.c: took the abort out of set_arch_mach so that objdump -i will
        still work. Now allows any architecture/machine to be set.

Wed Oct  2 13:50:35 1991  Steve Chamberlain  (steve at cygnus.com)

        * howto.c deleted and moved code to reloc.c

        * libbfd.h, libbfd-in.h removed $id stuff for real

        * cpu-h8300.c Made it match various different spellings of h8300.

        * archures.c: Took out the first char filter which made it only
        look for a cpu/arch match when the first chars of supplied and
        tested names were the same.

        * targets.c removed oasys stuff, pending someone to fix the bugs
        in it.


Tue Oct  1 12:29:44 1991  John Gilmore  (gnu at cygnus.com)

        * Makefile.in, configure.in, targets.c, elf.c:  Add preliminary
        ELF support good enough for GDB.
        * configure.in, config/h-amix, config/t-m68k-elf:  Handle
        m68k-cbm-svr4 host and target.
        * config/t-m68k-coff, t-m88k-coff, t-m88k-aout:  Make files nonempty
        so `diff' and `patch' can cope.

Tue Oct  1 11:24:31 1991  Steve Chamberlain  (steve at cygnus.com)

        * archures.c: removed texinfo error

        * init.c: added texinfo hooks, and removed initialization error
        message.

        * libcoff-in.h, libbfd-in.h removed $id field so cvs can merge
        without complaints.

Tue Oct  1 05:02:53 1991  John Gilmore  (gnu at cygnus.com)

        * cpu-i960.c:  Avoid numerical count of initializers.

        Vax Ultrix changes from David Taylor <taylor@think.com>:
        * host-aout.c:  Make little-endian vector really little-endian.
        * configure.in:  Separate vax and tahoe cases, handle ultrix.
        * config/t-vax:  Add trad-core.o.
        * config/h-vaxult:  New host system.

Mon Sep 30 15:13:46 1991  Steve Chamberlain  (steve at cygnus.com)

        * bfd-in.h VERSION, change version number to 0.18, this makes a
        gap, but now is the same as the linker version number.

        * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
        cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
        files will eventually contain processor specific bits for bfd,
        like strange relocation information and dis/assembly.  So far only
        the H8 has been even partially done.  This work also ties in with
        the change in handling architectures.

        * amdcoff.c: (a29k_reloc) fix error message.

        * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
        discover the architecture of the bfd. (sunos4_callback) calls the
        function bfd_set_arch_mach rather than stuffing stuff directly
        into the bfd. (sunos4_write_object_contents), changed names of
        accessor functions.

        * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
        setup the environment.

        * archive.c: (bfd_slurp_coff_armap) coff archives always have the
        headers in big endian format, regardless of the endianess of the
        host or target.

        * archures.c: totally changed. Now an architecture is represented
        with a pointer to an info structure rather than an enumerated type
        and a long. The old info is available as two elements in the
        structure.  Future enhancements to architecure support will
        involve pointers to methods being placed into the info structure.

        * bfd.c: changed the definition of the bfd structure for the new
        architecture stuff.

        * bout.c: (b_out_set_arch_mach) changed to use the new
        architecture mechanism.

        * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
        the new architecture mechanism.

        * configure.in: added h8 stuff.

        * ieee.c: too many changes to note.  Now ieee files written with
        bfd gas and ld can be read by gld and ieee only linkers and
        simulators.

        * libbfd.c, libbfd.h: changed prototype of bfd_write.

        * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
        than fixing the structure directly.

        * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
        than fixing the structure directly.

        * opncls.c: (new_bfd) makes sure that bfd_init has been called
        before opening a bfd.

        * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
        rather than fixing the structure directly.

        * targets.c: (target_vector) now by defining SELECT_VECS (perhaps

        obtrusive marks indicating .c origins.

        * bfd.texinfo: generalize most references to linker

Tue Aug 20 15:18:02 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)

        translate_to_native_sym_flags produce the above flags.


Wed Jul 31 09:53:52 1991  John Gilmore  (gnu at cygint.cygnus.com)

        * all files:  update copyright notices for GPL version 2.
        Install header comments and attribute most modules to their
        authors.  BFD's name is now officially "Binary File Descriptor",
        so remove any conflicting pejoratives.

        * Everything: created some new files, core.c format.c, reloc.c,
        section.c and syms.c to split the functionality a bit better.
        Cleaned up the rest of the files a bit, and added some
        documentation.


Mon Jul  1 13:29:47 1991  David Wood (wood at david.ultra.nya.edu)

        * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl
        really takes 3 arguments, patched code and ammended prototypes.

Fri Jun 14 13:19:40 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        * ../include/bfd.h (struct bfd_target): Added new field
        "align_power_min" which contains the minimum alignment for a
        section. This is used in coff_new_section_hook. The field
        insertion necessitates an update of all backends..

        * aoutf1.h jump table field inserted

        * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended

        table field inserted.

        * coffcode.h(just about everything) Now patches up symbol tables
        using a different mechanism. The Intel major bug has been fixed,
        and the linker can self host on the Aviion and be debugged with
        gdb.

        * ecoff.c: new include and jump table patch, i386coff.c: new
        include and jump table patch,  icoff.c: new include and jump table
        patch, ieee.c: can now read archives containing ieee modules.,

Thu Jun  6 18:27:38 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works

        * srec.c: now allows any number of sections to be created in a
        file. Outputs addresses of the right length.

Thu May 30 15:30:10 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        * bfd.c (bfd_check_format): Fixed problem where when a defaulted
        target didn't match, the format got set to the attempted match,
        breaking a future test.

        *../include/i386coff.h : fixed typo in type field with size

        * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added
        support in the jump table for the swapping routines exported to
        gdb. Now gdb works with the 386.

Tue May 28 17:21:43 1991  John Gilmore  (gnu at cygint.cygnus.com)

        * Merge in changes from gdb-3.95 release.
        Makefile.in:  Allow hmake and tmake files to add OFILES.
        aoutf1.h:
        bfd.c:  support specific targets as well as searching.  When
        searching, take default target in preference to others.
        bfd.doc:  typos
        ieee.c, oasys.c:  Avoid using the "tdata" macros left of assignment.
        liba.out.h:  Don't hard-code file offsets; use N_ macros for them.
        libbfd.h:  Support specific targets as well as searching.
        opncls.c:  Support specific targets as well as searching.
        targets.c:  Search is short-circuited if default target matches.
        liboasys.c, libieee.c:  Undo bothner changes that make macros
        work to the left of assignment, but which depend on the
        representations of different pointer types being the same.

Fri May 24 18:56:52 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        * i386coff.c: created.
        * coffcode.h: added support for 386.
        * Makefile.in: added support for 386.
        * ../include/i386coff.h: created

        (bothner)
        * opncls.c: Changed obstack_chunk_alloc use xmalloc

Mon May 20 17:12:17 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        * everything: Removed sysdep.h from bfd.h and put back into files
        from which it was split out. Now 64 bit version is built with a
        -DHOST_64_BIT="long long" on the compile line.

Fri May 17 19:35:26 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        Changed all the [get|put][name] routines to use  [get|put]_[size
        in bytes].

        Put in support for 64 bit work. Now two versions of bfd may be
        generated, according to the state of TARGET_64_BIT, one which is
        32 bit only, and one which is 64/32 bits.
        Created new back end 'demo64' to test 64 bit functionality.

        Renamed some files to work on DOS.

        * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added
        64bit transfer  * icoff.c: added 64bit transfer * ieee.c: name
        chage, 64 bit transfer. * liba.out.h: Split out common code from
        sunos and newsos into liba.out. Name changes and prototype mods. *
        libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h:
        prototypes for new functions. * libcoff.h: lint * libieee.h: make
        work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name
        change and 64bit stuff.* newsos3.c: common code removed, new jump
        table. * oasys.c: Name change * opncls.c: Portability fixes *
        srec.c: Name changes * sunos.c: Removed comon code. * targets.c:
        Added demo * aout32, aout64.c include  aoutx.h * bout.c: used to
        be called b.out.c * coffcode.h: used to be called coff-code.h, now
        64bit ized. * demo64.c: 64 bit a.out back end

Thu May 16 16:02:07 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
        from bothner
        * libieee.h: Make ieee_data and ieee_ar_data macros usable
        on LHS of assignment, even when using old compilers.
        * liboasys.h: Ditto for oasys_data and oasys_ar_data.
        * m68kcoff.c: Add enum-to-int casts to accomodate old compilers.
        * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR.
        * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined.
        * targets.c: Add declaration of newsos3_vec.

Mon May 13 10:03:29 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        * aout.c: fixxed some of the problems with filepos calculation.
        (swap_ext_reloc): fixed problem with creation of relocs.
        (aout_set_section_contents): fixed filepos problem

        * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
        (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
        (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
        (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
        cleaned up. (coff_write_object_contents) cleaned up.

        * ecoff.c: Totally different. Now supports ecoff fully.

        * icoff.c: fixed problems in relocation callout.

        * libcoff.h: (struct icofdata) removed hdr structure from tdata.

        * m68kcoff.c: updated target vector.

        * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
        choose_reloc_size. (sunos4_write_object_contents) now calls
        choose_reloc_size so outputs relocs correctly, also calculates the
        size of the sections correctly.



Fri May 10 16:58:53 1991  John Gilmore  (gnu at cygint.cygnus.com)

        Merge Per Bothner's changes to modularize BFD a.out a bit.

        * libbfd.h, libbfd.c (bfd_generic_get_section_contents):  Add.
        * ieee.c:  Cast enums to int before comparing them, for brain-
        dead compilers.
        * coff-code.h:  Remove coff_get_section_contents, and use the
        generic one instead.

        * aout.c:  Derive new module from sunos.c, containing generic
        support code for all kinds of a.out files.

        * sunos.c: Remove all code that goes in aout.c.  Split out
        machine dependent followup in sunos4_object_p into
        sunos4_callback.  Use JUMP_TABLE(aout) for the transver vector,
        and redefine only the names we CHANGE, not all the names.  Drop
        the little-endian vector, and rename the vector as sunos4 rather
        than generic.

        * b.out.c:  Use aout.c routines for most of the work.  Slight
        changes for the new regime.  Remove close_and_cleanup and
        get_section_contents in favor of generics.  New transfer vector
        regime.

        * newsos.c:  New support for Sony NEWS, another a.out format.

        * ecoff.c:  Remove close_and_cleanup.  New tvec regime.
        * icoff.c, m88k-bcs.c:  Add write_contents to tvec.
        * ieee.c, oasys.c:  Remove close_and_cleanup, add write_contents
        to tvec.
        * opncls.c (bfd_close):  Call format-dependent write_contents
        routine, if writing, before calling target-dependent
        close_and_cleanup routine (which is now always generic, I think).
        * srec.c:  Use bfd_alloc instead of malloc.  Remove
        close_and_cleanup and move code from it to
        srec_write_object_contents.  Add write_contents to tvec.
        * targets.c:  Remove a.out little vector, replace a.out big
        vector with SunOS vector.  FIXME:  Need Vax support again now.

        * libbfd.h:  Add write_contents format-dependent-vector to the
        bfd_target vector.  Supply a generic close_and_cleanup routine.
        * liba.out.h:  Handle the new aout.c split.  Add prototypes for
        all routines defined in aout.c.  Rename "sunos" things to "aout"
        things.  Add a few fields where needed for various formats.
        * Makefile.in:  Add aout.c and newsos.c.

        * archive.c, ieee.c, oasys.c:  Lint.

Fri May 10 12:34:48 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        * ../include/bfd.h
        changed forward declaration struct stat; to reduce warnings. Changed
        comment on bfd_h_<x>_x.

        * ../include/m68kcoff.h, ../include/intel-coff.h,
        ../include/m88k-bcs.h
        Now there are two incarnations of relocs, linenos and syments. One for
        internal digestion, and one full of char arrays for I/O. The original
        names have gone to detect errors.

        * Makefile.in, m68kcoff.c, targets.c
        Test new structure code with a 68k coff implementaion

        * coff-code.h, icoff.c, coffswap.c, libcoff.h
        Fixed all the places where there were problems with the size and
        alignments of structures on disk and structures in memory. #ifed out
        all the code in coffswap.c, since it should be done using the target
        swap routines now.

Thu May  9 11:00:45 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        * ieee.c (do_one, ieee_slurp_section_data): now supports the load
        multiple reloc command.

        * sunos.c (sunos4_set_section_contents): Made it so that sections
        are always padded to their alignment size.

Sat May  4 15:49:43 1991  John Gilmore  (gnu at cygint.cygnus.com)

        * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
        Clean up types and such (saber C problems).
        * ecoff.c:  Clean up types and such.  Remove routines that are
        not used.  Fix up reading and swapping of shorts from files.

   Notes on bfd-0.5.2-patch1a, from Per Bothner:

        * a.out.vax.c: Remove two bogus "static" from prototypes.

        * ecoff.c: Got rid of lots of non-working junk (that had
        been copied directly from coff-code.h).
        Updated to be consistent with updates to icoff.c and coff-code.h.

        * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
        if they're missing (as they are in (BDS-4.3-based) NewsOS-3).

        * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
        but until the target_vector is automatically generated,
        it's as good as any. Note that the text offset is the only
        difference between NewsOS and SunOs (including magic numbers).
        (Most of the sunos_* routines should to renamed bsd_*
        and move to a bsd.c file. Then (and when the target_vector
        is automatically generated) it might make sense to create
        a separate Sony target.)

        * sysdep.h: Don't declare fread and fwrite. Causes trouble
        on some systems, and doesn't help on others.
        Similarly, only define X_OK if not already defined.

        * trad-core.c: Don't include sys/stat.h - at least
        on NewsOS 3, it has already been included.

Tue Mar  5 01:47:57 1991  John Gilmore  (gnu at cygint.cygnus.com)

        * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
        bfd_coff_swap_lineno):  Export the routines that byte-swap COFF
        symbol tables if necessary when reading them in, so gdb can use
        them.  Add "bfd_coff_" to the names so they won't conflict with
        names in calling programs.  FIXME-soon:  if coff-code.h is
        included in two BFD modules, this will cause duplicate
        definitions; the routines should be exported to a separate,
        common, module (probably along with a mess of other ones).

Sat Mar  2 12:11:26 1991  John Gilmore  (gnu at cygint.cygnus.com)

        Improve modtime support.

        * bfd.h:  Add boolean mtime_set, and declare bfd_get_mtime.
        Remove #define for bfd_get_mtime.  Remove gratuitous comment.
        * bfd.c (bfd_get_mtime):  New fn, caches mtime, gets if not cached.
        BUG:  archive members still do not get correct mod times.

        Improve floating point support for core files.

        * sunos.c (struct core):  Change void *fpa_dummy to double fp_stuff.
        (sunos4_core_file_p):  Create a second registers section in the
        core file, called ".reg2", for the float registers.

Thu Feb 14 15:49:06 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)

        * many changes to improve archive handling; found a logic flaw in
          bfd_check_format which only just happened to work by cooncidence.

Thu Feb 14 07:53:16 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        * bfd.c (bfd_perform_relocation): fixed to use output_offsets
        correctly.

        * bfd.h: changed type of udata in asymbol to void *, like it
        should be. Added bfd_reloc_dangerous enum member.

        * coff-code.h: Fixed it so that internally generated symbols get
        their values relocated correctly in all cases. Removed calls to
        xmalloc.

        * icoff.c: Not understanding the destination symbol of a reloc is
        not a failure any more, just 'dangerous'. This allows linking of
        b.out and coff images.

        * sunos.c: Cleaned up the way that ZMAGIC section sizes are
        calculated.


Tue Feb 12 13:25:46 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        * sunos.c (translate_to_native_sym_flags): fixed
        sym_pointer->n_value so that symbols on the way out get their
        section relative values calculated correctly.

        * coff-code.h (mangle_symbols): fixed problem where tags were not
        being relocated for structs, enums, unions. Also various lints.

Mon Feb 11 19:52:26 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)

        * archive.c (get_elt_at_filepos): system_call_error returned
          incorrectly.

Sun Feb 10 23:18:40 1991  Gumby Vinayak Wallace  (gumby at cygint.cygnus.com)

        * Resolve the use of no_error and system_call_error.
          The bfd library itself now will never set bfd_error to
          no_error.

          The code still needs to be combed to make sure all the error
          codes are correct.  I suspect they are not always set correctly.

        * The names of all the messages have _ prepended because the sun
          bundled compiler can't distinguish from a macro which takes an
          argument and the same identifier in a non-macro context.

        * The reason for the above being that entry points which used to
          be trampoline functions are now just macros which expand to a
          direct call through the bfd's xfer vector.

        * (../include/intel-coff.h) F_AR32WR: fix this constant.  Why
          must gas have its own version of everything (the gas version
          had the correct value)

Tue Feb  5 11:46:53 1991  Steve Chamberlain  (steve at cygint.cygnus.com)

        * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
        properly support i960 architecture and output correct reloc stuff.

        * bfd.h: added prototype for bfd_printable_arch_mach, added
        BFD_FAIL

        * coff-code.h: Applied patches from chrisb to support i960
        architecture, zero relocs and swap them correcly and conditionally
        compiled the timestamp.

        * sunos.c: Made the default section alignment 2^3 so that doubles
        are done properly. Fixed the same reloc bug that was in b.out.c

        * sysdep.h: Now compiles on a Posix box

Wed Jan 30 21:36:26 1991  John Gilmore  (gnu at cygint.cygnus.com)

        * icoff.c:  Fix comment on big-endian version.
        * coff-code.h:  Make HAS_RELOC really work (it's backwards from
        F_RELFLG).  Set F_AR32WR in output files if little endian
        architecture.

Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com

        * archures.c fixed =/== typo

        * sunos.c added architecture stuff for output. Fixed
        bug where files where vma(data) != size(text)
        were processed wrong.

        * coff-code.h added a lint cast

        * (../include/a.out.sun4.h) fixed it so zmagic
        worked

Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com

        * archive.c removed loads of includes, and fixed bug where string
        table didn't have a null at the end.

        * bfd.c fixed includes, added symbols argument to
        canonicalize_reloc entry point.

        * libbfd.c fixed includes and added some lint patches.

        * targets.c added both sorts of intel coff.

        * b.out.c fixed included, changed was the canonical
        relocs were done.

        * icoff.c added support for callj and big and little
        enidian tables.

        * opncls.c added chmod+xing for files with EXEC_P set.

        * sunos.c fixed includes. Changed default section
        alignement to words. Fixed relocation stuff to work with
        new scheme

        * bfd.h various new types added, prototype for new
        reloc calls, changed bfd->iostream to a void *
        to including files don't need stdio.h.

        * libcoff.h added conversion table to tie relocs to
        canonical symbols

        * sysdep.h created

        * coff-code.h fixed includes. Added code to support
        big and little endian formats. Various lints. Better
        processing of symbols. Changed reloc stuff to new
        order

        * libbfd.h fixed includes


Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com

        * bfd.h changed name of alignment entry in sec_struct to
        alignment_power, because of conflicting uses within bfd.
        Now it should be obvious that it's a 2**n alignment
        specifier. Removed start_pad, end_alignment, block, minsize,
        output_file_alignment, subsection_alignment and original_vma fields.
        Added align_power() macro. Fixed bfd_section_alignment
        acessor macros. Added bfd_symbol_same_target macro.

        * b.out.c (b_out_write_object_contents) fixed to use
        new alignment member. Fixed (callj_callback) to use section
        relative symbols properly.

        * sunos.c (sunos4_object_p) fixed to use new alignment_power.
        Fixed (translate_from_native_sym_flags) to correctly make
        symbols section relative.

        * bfd.c (bfd_errmsg) fixed various enum cast problems.
        (bfd_make_section) took out initialization of obsolete members.
        (bfd_print_symbol_vandf) added

        * opncls.c (bfd_create) created.

        to obsolete members. (make_a_section_from_file) added
        conversion between alignment types. (coff_symbol_from)
        added. (coff_count_linenumbers) only counts linenumbers
        if symbol is of coff-type. (coff_mangle_symbols) only
        heavily mangles symbols if symbol is coff-type.
        (coff_write_symbols) various lints. (coff_write_object_contents)
        various lints and modification for alignment conversion.
        (coff_slurp_relocs) fixed for use with new asection shape.

Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com

        * archive.c lots of lint

        * b.out.c added callj relocation support, upgrated reloc howto.
        Fixed so that asymbol and reloc records are output
        correctly.

        * bfd.c lots of lint, support for new bfd entry point
        bfd_print_symbol.

        * bfd.h changed definition of asymbol to contain pointer to
        owning bfd, removed target dependencies.

        * cache.c took out print statements, put in BFD_ASSERT calls.

        * coff-code.h various lints, corrected linenumber output
        functionality. Added support for new style asymbols and
        bfd_print_symbol. Fixed so that asymbol and
        reloc records are handled correctly. Added timestamp.

        * icoff.c Added support for new howto shape.

        * liba.out.h Added support for new asymbol shape

        * libbfd.c various lints

        * sunos.c  various lints. Added support for new asymbol shape
        and bfd_print_symbol.

Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com

        * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
        pointer lint. Added support for callj relocation. Fixed bug where
        the last 32 bytes of the text section were overwritten by data. Fixed bug
        where archives of b.out didn't work due bfd_slurp_extended_name_table
        returning false.

        * sunos.c added support for n_other field. Braced the howto table so
        that it won't be affected by any lengthing of the howto struct typedef.
        Various lints

        * bfd.h added support for n_other field, added special_function
        reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
        macros.

        * bfd.c upgraded bfd_perform_relocation, various lints.

Wed Jan 16 01:55:53 1991  John Gilmore  (gnu at rtl)

        * ChangeLog:  Started ChangeLog for BFD.
        * ToDo:  Create file for suggestions.

        * Makefile:  Support easy loading into Saber C.
        Add dependencies for icoff.o and bcs88kcoff.o.
        Rename coff.c to coff-code.h.  Change callers.

        * bfd.c (bfd_check_format):  Allow the check_format routines
        to return the desired target vector, rather than just a Boolean.
        bfd.h (bfd_check_format):  Change function pointer return type.
        archive.c (bfd_generic_archive_p):  change callee.
        b.out.c (b_out_little_object_p, b_out_big_object_p,
        b_out_real_object_p):  change callee.
        libbfd.c (_bfd_dummy_target):  Dummy routine replacing bfd_false
        in check_format transfer vectors that need a filler.
        libbfd.h (bfd_generic_archive_p, _bfd_dummy_target):  Fix decls.
        bcs88kcoff.c:  change callee.
        coff-code.h (coff_real_object_p, coff_big_object_p):  change callee.
        icoff.c:  change callee.
        sunos.c (sunos4_object_p, sunos4_core_file_p):  change callee.

        * libbfd.c (zalloc):  It should actually zero the storage!
        This was commented out for some reason.

        * libbfd.h:  Add malloc, xmalloc, memcpy, and fatal decls.
        This is so callers can avoid <stdlib.h> which doesn't exist
        on older systems.

        * bfd.c (map_over_sections):  Add debugging code, since I
        noticed the section count for sunos core files was bad, but only
        GDB had detected the problem.
        (bfd_set_section_lineno_size, bfd_set_section_linenos,
        bfd_get_section_linenos):  Remove obsolete functions.
        (bfd_apply_relocations):  Use longs, not ints, for the math.

        * bfd.h:  Declare enum boolean and struct bfd_target as well
        as typedefs for them.  Remove obsolete
        bfd_get_section_lineno_size.

        * cache.c:  Make the "fdopen" support work.  Keep better track
        of how many files are open.  Centralize the opening of files
        and be sure bfd_open[rw] actually try to open the file.  Evade
        linked list initialization problems.

        * b.out.c, coff-code.h, opncls.c, sunos.c:  lint.

        * coff-code.h (coff_slurp_symbol_table):  Null-terminate symtab names.

        * cplus-dem.c:  Delete file, since it is not part of BFD.

        * opncls.c (bfd_openr):  Eliminate misplaced #if 0 code.
        (bfd_openr, bfd_openw):  Actually open the file, give error now.

        * sunos.c (sunos4_core_file_p):  Set section count.
        (sunos4_set_section_linenos, stab_names, fprint_name):  Eliminiate
        obsolete definitions.
        (_write_symbol_table):  Initialize <idx> counter.
        (foop):  Eliminate debugging code.
