Mon Mar 28 12:53:27 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        * configure.in (powerpc-*-aix*): New target; use rs6000.mt.

        * aoutx.h (translate_from_native_sym_flags): Set SEC_RELOC flag
        for generated constructor section.

Sat Mar 26 10:25:43 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

        * som.c (som_get_section_contents): New function.  Do not try
        to actually read data from a section that doesn't have either
        SEC_LOAD or SEC_DEBUGGING set (eg $BSS$) just return true.

        * libbfd.c (bfd_read): Set bfd_error as appropriate for a short
        read. (bfd_error_system_call or bfd_error_file_truncated).

        Changes to support linker relaxing of embedded MIPS PIC code to
        use a five instruction sequence for function calls which are out of

        the debugging information if it has already been read.
        (ecoff_indirect_link_order): Handle _cooked_size being different
        from _raw_size.  Don't reread the contents or the relocs if they
        have already been read in.

        functionname_ptr to be set to a symbol name, so prepend
        symbol_leading_char.

Thu Mar 24 11:33:46 1994  Steve Chamberlain  (sac@jonny.cygnus.com)

        * coff-h8300.c (h8300_reloc16_extra_cases): Add relaxing info

        relocs when allocating space for relocations.  Set SEC_RELOC flag
        for any section which has relocs.  Handle link_order relocs in
        link_order loop.  Use _bfd_generic_link_add_symbols_collect for
        add_symbls entry point.

        * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
        counting relocs.  Set SEC_RELOC flag for any section which has

        (_bfd_generic_link_add_symbols_collect): New function, like
        _bfd_generic_link_add_symbols but also collect constructors and
        destructors by name as collect2 does.
        (generic_link_add_symbols): New function, like old

        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
        extended name table.

Mon Mar 21 12:28:19 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        Support for link_order types which generate relocs in order to

        (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
        Don't pass bitsize to constructor call back.  Pass BFD_RELOC_CTOR
        instead of bitsize to add_to_set call back.
        (_bfd_generic_final_link): Account for link_order relocs when
        allocating space for relocations.  Handle them in link_order loop.
        (_bfd_generic_reloc_link_order): New function.

        bfd_link_hash_weak case to use .sc rather than .st.
        (ecoff_reloc_link_order): New function.
        * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
        BFD_RELOC_CTOR.

        * 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  (law@snake.cs.utah.edu)

        * 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  (kingdon@lioth.cygnus.com)

        * 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.
        * cisco-core.c: New file.
        * Makefile.in: Change accordingly.
        * configure.in: Recognize cisco_core_vec.
        * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
        * targets.c: Add cisco_core_vec.
        * bfd-in2.h: Rebuilt.

Fri Mar 18 18:13:49 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

        * 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  (raeburn@cujo.cygnus.com)

        * 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  (raeburn@cujo.cygnus.com)

        * 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  (kingdon@lioth.cygnus.com)

        * 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  (ian@tweedledumb.cygnus.com)

        * 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  (djm@thepub.cygnus.com)

        * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
        From sukes@glue.umd.edu (Tasuki Hirata).

Wed Mar 16 07:55:54 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * 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).

        * 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$0\001", not just "L$".

        no symbol.
        (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
        undefined symbols.  Correctly distinguish between debugger symbols

        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

        and STYP_COMMENT.

Wed Mar  9 17:17:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

        * 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.

        * elfcode.h (bfd_section_from_shdr):  Handle SHT_DYNAMIC section like
        SHT_PROGBITS section.

        TRAD_CORE_STACK_OFFSET.
        * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
        TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.

        (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
        right in the original relocation and the stub's relocation.

        * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo.  Delete
        unused symbols argument.

        * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
        than asymbol * for original target symbol.  All callers changed.
        Set reloc->sym_ptr_ptr appropriately.

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

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

        error code propogation working.  Work on spacing and indention.
        Add FIXMEs for unresolved problems.  Use enums rather than
        #defines for lots of things.  Merge two functions which build
        linker stubs into a single function (so they can easily share a
        ton of common code).

        static vars together.  Collapse common case statements together
        in many places.  Use default case when possible instead of listing
        each case separately.  Abort for bad errors until we get error
        code propogation working.  Work on spacing and indention problems.
        Add FIXMEs for some unresolved problems.  Delete hopelessly broken 
        COMPLEX relocation support (it's never used anyway).
        (hppa_elf_rebuild_insn): Delete.  Moved into libhppa.h.

        * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
        number rather than HP9000S800_ID.  Note som.c is careful

        unrelocated contents, the section's raw size is always the one to
        use for bounds checking.

        bout.  Default with no version number is still bout.  Support

        STYP_INFO for the type of a section named .debug.
        (coff_add_missing_symbols): Don't define if RS6000COFF_C.
        (coff_write_object_contents): If RS6000COFF_C, don't call
        coff_add_missing_symbols.
        (coff_slurp_symbol_table): If RS6000COFF_C, then if the last aux
        entry has type STY_LD change the x_scnlen into a pointer to a
        symbol and set fix_scnlen.  Also, for a C_BSTAT symbol, change the
        value into a pointer to a symbol and set fix_value.
        * libcoff.h: Rebuilt.

        .debug section.
        (coff_get_normalized_symtab): Clear new fix_value and fix_scnlen
        fields.  If the string offset is 0, always use an empty string as

        bfd_som_set_subsection_attributes): Change parameters from char
        to int.  Following a prototype with an old-style function definition

        The sparc (and possibly other?) NLM format requires a different
        way to write exports, so add a write_export field to the backend
        data (and set it to NULL for everything but the sparc).

        * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
        in the backend accessor macros; that should no longer be possible.

        * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
        in last change.  Always rebuild symbol extension section the first

        * config.bfd: Use bigmips for mips*-*-bsd*.

Mon Nov  1 14:30:09 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
        Handle symbol number of zero.

        * reloc.c (enum bfd_reloc_code_real): Added
        BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
        BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
        * bfd-in2.h: Rebuilt.
        * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
        BFD_RELOC_MIPS_LITERAL.
        * elf32-mips.c (mips_reloc_map): Handle new relocs.
        (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp

        MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
        (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
        MY_bfd_seclet_link): Define.

        MY_canonicalize_reloc, MY_write_object_contents): Don't define in
        terms of MY, because that causes a recusive invocation of CAT when
        expanded within JUMP_TABLE, and ANSI compilers don't expand
        recursive macros.
        * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
        MY_reloc_howto_type_lookup, and don't define in terms of MY.
