    for first character in an extended name.
    (_bfd_write_archive_contents): If ar_padchar == '/', then use
    "//" as the name of the special archive member holding the

Mon Mar 21 12:28:19 1994  Ian Lance Taylor  ([e-mail])

    Support for link_order types which generate relocs in order to
    support -Ur in the linker.

    from call to _bfd_generic_link_add_one_symbol.
    (_bfd_generic_link_add_one_symbol): Remove bitsize argument.

    allocating space for relocations.  Handle them in link_order loop.
    (_bfd_generic_reloc_link_order): New function.

    (_bfd_count_link_order_relocs): Declare.
    * libbfd.h: Rebuilt.
    * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
    call to _bfd_generic_link_add_one_symbol.
    (NAME(aout,final_link)): Account for link_order relocs when

Sun Mar 20 09:24:36 1994  Jeffrey A. Law  ([e-mail])

    * bfd/som.c (som_begin_writing): Fix thinko (off by one error).

    * som.c (bfd_section_from_som_symbol): Only to do the value
    comparison for function symbols within executables.

    * som.c (bfd_section_from_som_symbol): Renamed from
    som_section_from_subspace_index.  Pass in a native SOM symbol.
    For executables, iterate through the sections to find out
    which contains the symbol's address rather than using the
    symbol_info field.  (symbol_info has a different meaning for
    dynamicly linked executables.)

    * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
    bfd_zmalloc.

    * som.c (som_begin_writing): Fix braino (one call to align
    space/subspace data was done unconditionally rather than
    just for executables.)

    * som.c (som_begin_writing): Align text in all executables to
    make HPUX kernel happy.  Fixes strip/objcopy for shared
    executables.

Sat Mar 19 07:06:59 1994  Jeffrey A. Law  ([e-mail])

    * som.c (som_begin_writing): Account for alignment needs of
    subspaces too when writing executables.  Never request a negative
    bss size.  Fixes some problems with demand paged executables,
    still having problems with pure executables and shared executables.

Fri Mar 18 19:12:47 1994  Jim Kingdon  ([e-mail])

    * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
    bfd_zalloc for rawptr, because later on we may call free, not
    bfd_release, on it.

    * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
    * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.

    * som.h (som_copyable_section_data_struct): New structure
    containing all the private section information which needs
    to be copied from input section to output section during
    objcopy or strip.
    (som_section_data_struct): Remove several fields now in
    som_copyable_section_data_struct.  Make the space and
    subspace dictionaries be pointers (to save space when
    only reading objects).

    * som.c (bfd_som_set_section_attributes): Now returns a boolean;
    some references changed.  Allocate a copyable data stucture if
    none exists.  Store info into the copyable data structure.
    (bfd_som_set_subsection_attributes): Likewise.
    (som_is_space, som_is_subspace, som_is_container): New functions.
    Use these instead of directly accessing private data.
    (som_prep_headers): Allocate space and subspace headers here.
    Fill in some fields in the space/subspace headers from the
    copyable data.
    (som_bfd_copy_private_section_data): Only copy the stuff
    that we really need to make objcopy and strip work.  Allocate
    the copy_data structure for the output bfd before copying.

    * som.h (struct som_exec_data): New structure to hold exec
    info that must be preserved when running objcopy/strip.
    (struct somdata): Add new "exec_data" field and accessor
    macro.  Add some comments on how the various fields are used.
    (som_section_data_struct): Make is_space and is_subspace bitfields.
    Delete unused subspace_index.  All references now use the
    target_index field within the section structure itself.

    * som.c (make_unique_section): Delete unused declaration.
    (som_bfd_copy_private_bfd_data): New function.
    (som_object_setup): Allocate space for and save exec information
    that needs to be copied during objcopy/strip.
    (som_mkobject): Do not allocate space for a file header here.
    It is not used when only reading SOM objects.
    (som_prep_headers): Allocate space for and attach a file header
    to the output bfd.  For executables, use the saved system_id
    value rather than trying to guess the right value.  Do not abort
    wwhen setting file_hdr->entry* for executables.
    (som_begin_writing): For executables, set the exec_entry and
    exec_flags fields.
    (som_copy_private_backend_section_data): Always return a value.

    * libhppa.h (PA_PAGESIZE): Define.

    * som.c (SOM_ALIGN): Define.
    (som_begin_writing): If writing an executable, initialize all
    fields in the exec header to zero.  Update fields in the exec
    header as sizes of loadable subspaces are computed.  Carefully
    preserve alignments when building executables.  Actually write the
    exec after all the fields are filled in.

        * Better long-filename handling.  Reads SOM ABI compliant extended
    names, but doesn't quite write compliant extended names yet.
    * som.c (som_slurp_extended_name_table): Delete function.  The
    generic code will handle things correctly.
    (som_slurp_armap): Seek to the beginning of the next member.
    (normalize): New function.
    (som_bfd_ar_write_symbol_stuff): Take the size of the extended
    name table into account when computing the file offsets in the
    SOM dictionary.  Make sure to align to an even boundary.
    (som_write_armap): Initialize the checksum to zero.
    (ar_maxchars): Fix.  Opps.

Fri Mar 18 20:35:24 1994  Ken Raeburn  ([e-mail])

    * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
    machine.  Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

Thu Mar 17 18:26:46 1994  Ken Raeburn  ([e-mail])

    * bfd-in.h (BFD_VERSION): Use @VERSION@.
    * Makefile.in (bfd.h): Replace it with contents of VERSION file.
    * bfd-in2.h: Regenerated.

    * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
    this was also named trad_unix_bfd_copy_private_bfd_data.

Thu Mar 17 10:37:07 1994  Jim Kingdon  ([e-mail])

    * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
    elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
    returns NULL, it is not an error.  It's possible that some of
    these checks are not necessary (because the size can never be
    zero), but putting in the checks is the conservative thing to do
    in light of the fact that some of these malloc calls replaced
    unchecked alloca calls, in which a zero argument would work fine.

Thu Mar 17 11:44:45 1994  Ian Lance Taylor  ([e-mail])

    * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
    duplicate definition.
    (osf_core_bfd_is_local_label): Define.

    * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
    if malloc (0) fails.  bfd_canonicalize_reloc returning 0 is not a
    failure indication, it merely means there are no relocs.

    * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
    after NAME, since SunOS /bin/cc can't handle it.

Wed Mar 16 16:43:33 1994  David J. Mackenzie  ([e-mail])

    * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
    From [e-mail] (Tasuki Hirata).

Wed Mar 16 07:55:54 1994  Jim Kingdon  ([e-mail])

    * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
    all that convoluted stuff with NAME, CAT3, etc.  The convoluted
    stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).

Wed Mar 16 00:02:05 1994  Jeffrey A. Law  ([e-mail])

    * som.c (som_prep_for_fixups): Detect section symbols based
    on either the lack of private data or the symbol flags.  Do not
    munge section symbol names anymore -- they no longer confuse GDB.
    (som_begin_writing): Leave space for an exec header if writing
    an executable.
    (som_slurp_symbol_table): Recognize both forms of section symbol
    names "L$0\002" and "$<FOO>$".  Change the name of "L$0\002"
    section symbols to be the name of the section they represent.
    Debugging  symbols begin with "L$0\001", not just "L$".

Tue Mar 15 22:58:28 1994  Jeffrey A. Law  ([e-mail])

    libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
    Default new vectors for copying private backend data to bfd_true.
    Default new vector for determining if a symbol is a local label
    to bfd_generic_is_local_label.

    * som.c (som_bfd_copy_private_section_data): New function.
    (som_bfd_is_local_label): New function.
    (som_bfd_copy_private_bfd_data): For now default to bfd_true.

    * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.

Tue Mar 15 04:41:13 1994  David J. Mackenzie  ([e-mail])

    * Most files:
    Replace DEFUN and DEFUN_VOID with K&R-style function definition.
    Indent some of them to GNU standards.

    * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
    cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
    elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
    libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
    Update copyright years.

Mon Mar 14 11:41:23 1994  Jeffrey A. Law  ([e-mail])

    * som.c (som_prep_for_fixups): A relocation involving the section
    symbol for the *ABS* section is really a relocation involving
    no symbol.
    (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
    undefined symbols.  Correctly distinguish between debugger symbols
    and section symbols.

    * som (setup_sections): Set SEC_DEBUGGING and the section attributes

    prepared to handle multiple sections with the same name.
    (setup_sections): Allocate space on the BFD's obstack to hold
    section names.  Use bfd_make_setion_anyway rather than the
    obsolete make_unique_section.
    (som_prep_headers): Choose the correct SOM magic number based
    on the BFD's flags.
    (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

    recovery of the dynamic info from a stripped executable.
    * ecoff.c (ecoff_styp_to_sec_flags):  Handle STYP_PDATA, STYP_XDATA
    and STYP_COMMENT.

Wed Mar  9 17:17:53 1994  Jim Kingdon  ([e-mail])

    * libbfd-in.h: Remove alloca cruft.  It was missing some necessary
    cruft (like the #pragma alloca for AIX).
    In addition to that problem, the C alloca calls xmalloc, which
    means checking for being out of memory can't work right.  The
    following changes remove all uses of alloca from BFD.
    * hosts/solaris2.h: Remove alloca cruft.
    * som.c: Replace alloca with a fixed size auto array.
    * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
    ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,

    * elf32-hppa.h, elfcode.h:  Replace uses of Elf*_Half, Elf*_Word,
    Elf*_Off typedefs by their expansion, the typedefs have been
    removed from include/elf/internal.h.
    * elfcode.h (bfd_section_from_shdr):  Handle SHT_DYNAMIC section like
    SHT_PROGBITS section.

    return from bfd_seek indicates an error.
    New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
    TRAD_CORE_STACK_OFFSET.
    * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
    TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.

Wed Mar  2 11:57:03 1994  Jeffrey A. Law  ([e-mail])

    * som.[ch]: Do not include libhppa.h in som.c, instead include
    it in som.h.

    * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
    include it in elf32-hppa.h.

    * som.c (log2): Return -1 on error rather than aborting.
    (setup_sections): Bubble up an error from log2.

    * Changes to make HP C compiler happy in both traditional
    and ANSI mode.
    * som.c (hppa_som_gen_reloc_type): Use correct enum type for
    field parameter.
    (bfd_som_set_section_attributes): Use unsigned int rather than
    unsigned char to avoid GNU-C extensions.
    (bfd_som_attach_aux_hdr): Return a boolean to indicate success
    or failure rather than aborting on failure.

    * som.h (bfd_som_set_section_attributes): Fix prototype to match
    som.c changes.
    (bfd_som_attach_aux_hdr): Add prototype.
    (hppa_som-gen_reloc_type): Likewise.

    * elf32-hppa.c: Add a couple casts to make HP compiler happy.

    (hppa_elf_look_for_stubs_in_section): No longer need symbols
    argument.  Use the output symbols when canonicalizing the relocs,

    * linker.c (_bfd_generic_link_output_symbols): Do not
    rebuild/clobber the output symbols if they already exist.

    link_order size field against cooked size, not raw size, of input
    section.

    * bout.c (b_out_get_reloc_upper_bound): For BSS section, just

    bother processing them.

    * sunos.c (MY(read_dynamic_relocs)): Compare info->dynrel with NULL,
