484 in executables left by the HP linker. Does not rely on subspace
485 alignments as subspaces are *NOT* guaranteed to be properly
486 aligned in an executable (can you believe that!).
488 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
490 * som.c (som_get_section_contents): New function. Do not try

499 (like som_object_p) override the error status set by bfd_read.
501 * aix386-core.c, aout-encap,c archive.c, bout.c: Likewise.

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

664 for first character in an extended name.
665 (_bfd_write_archive_contents): If ar_padchar == '/', then use
666 "//" as the name of the special archive member holding the
669 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
671 Support for link_order types which generate relocs in order to
672 support -Ur in the linker.
673 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
674 from call to _bfd_generic_link_add_one_symbol.
675 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
676 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
677 instead of bitsize to add_to_set call back.
678 (_bfd_generic_final_link): Account for link_order relocs when
679 allocating space for relocations. Handle them in link_order loop.
680 (_bfd_generic_reloc_link_order): New function.
681 (_bfd_default_link_order): If a reloc_link_order is seen here,
683 (_bfd_count_link_order_relocs): New function.

692 allocating space for relocations. Handle them after handling all
694 (aout_link_reloc_link_order): New function.

703 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
705 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
707 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym

714 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
716 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
718 * som.c (bfd_section_from_som_symbol): Only to do the value
719 comparison for function symbols within executables.
721 * som.c (bfd_section_from_som_symbol): Renamed from
722 som_section_from_subspace_index. Pass in a native SOM symbol.
723 For executables, iterate through the sections to find out
724 which contains the symbol's address rather than using the
725 symbol_info field. (symbol_info has a different meaning for
726 dynamicly linked executables.)
728 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
731 * som.c (som_begin_writing): Fix braino (one call to align
732 space/subspace data was done unconditionally rather than
733 just for executables.)
735 * som.c (som_begin_writing): Align text in all executables to
736 make HPUX kernel happy. Fixes strip/objcopy for shared
739 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
741 * som.c (som_begin_writing): Account for alignment needs of
742 subspaces too when writing executables. Never request a negative
743 bss size. Fixes some problems with demand paged executables,
744 still having problems with pure executables and shared executables.
746 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
748 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
749 bfd_zalloc for rawptr, because later on we may call free, not
752 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
753 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
754 * cisco-core.c: New file.

756 * configure.in: Recognize cisco_core_vec.
757 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
758 * targets.c: Add cisco_core_vec.
759 * bfd-in2.h: Rebuilt.
761 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
763 * som.h (som_copyable_section_data_struct): New structure
764 containing all the private section information which needs
765 to be copied from input section to output section during
767 (som_section_data_struct): Remove several fields now in
768 som_copyable_section_data_struct. Make the space and
769 subspace dictionaries be pointers (to save space when
770 only reading objects).
772 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
773 some references changed. Allocate a copyable data stucture if
774 none exists. Store info into the copyable data structure.
775 (bfd_som_set_subsection_attributes): Likewise.
776 (som_is_space, som_is_subspace, som_is_container): New functions.
777 Use these instead of directly accessing private data.
778 (som_prep_headers): Allocate space and subspace headers here.
779 Fill in some fields in the space/subspace headers from the
781 (som_bfd_copy_private_section_data): Only copy the stuff
782 that we really need to make objcopy and strip work. Allocate
783 the copy_data structure for the output bfd before copying.
785 * som.h (struct som_exec_data): New structure to hold exec
786 info that must be preserved when running objcopy/strip.
787 (struct somdata): Add new "exec_data" field and accessor
788 macro. Add some comments on how the various fields are used.
789 (som_section_data_struct): Make is_space and is_subspace bitfields.
790 Delete unused subspace_index. All references now use the
791 target_index field within the section structure itself.
793 * som.c (make_unique_section): Delete unused declaration.
794 (som_bfd_copy_private_bfd_data): New function.
795 (som_object_setup): Allocate space for and save exec information
796 that needs to be copied during objcopy/strip.
797 (som_mkobject): Do not allocate space for a file header here.
798 It is not used when only reading SOM objects.
799 (som_prep_headers): Allocate space for and attach a file header
800 to the output bfd. For executables, use the saved system_id
801 value rather than trying to guess the right value. Do not abort
802 wwhen setting file_hdr->entry* for executables.
803 (som_begin_writing): For executables, set the exec_entry and
805 (som_copy_private_backend_section_data): Always return a value.
807 * libhppa.h (PA_PAGESIZE): Define.
809 * som.c (SOM_ALIGN): Define.
810 (som_begin_writing): If writing an executable, initialize all
811 fields in the exec header to zero. Update fields in the exec
812 header as sizes of loadable subspaces are computed. Carefully
813 preserve alignments when building executables. Actually write the
814 exec after all the fields are filled in.
816 * Better long-filename handling. Reads SOM ABI compliant extended
817 names, but doesn't quite write compliant extended names yet.
818 * som.c (som_slurp_extended_name_table): Delete function. The
819 generic code will handle things correctly.
820 (som_slurp_armap): Seek to the beginning of the next member.
821 (normalize): New function.
822 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
823 name table into account when computing the file offsets in the
824 SOM dictionary. Make sure to align to an even boundary.
825 (som_write_armap): Initialize the checksum to zero.
826 (ar_maxchars): Fix. Opps.
828 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
830 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
831 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
833 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
835 * bfd-in.h (BFD_VERSION): Use @VERSION@.
836 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
837 * bfd-in2.h: Regenerated.
839 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
840 this was also named trad_unix_bfd_copy_private_bfd_data.
842 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
844 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
845 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
846 returns NULL, it is not an error. It's possible that some of
847 these checks are not necessary (because the size can never be
848 zero), but putting in the checks is the conservative thing to do
849 in light of the fact that some of these malloc calls replaced
850 unchecked alloca calls, in which a zero argument would work fine.
852 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
854 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
855 duplicate definition.
856 (osf_core_bfd_is_local_label): Define.
858 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
859 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
860 failure indication, it merely means there are no relocs.
862 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
863 after NAME, since SunOS /bin/cc can't handle it.
865 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
867 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
868 From sukes@glue.umd.edu (Tasuki Hirata).
870 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
872 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
873 all that convoluted stuff with NAME, CAT3, etc. The convoluted
874 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
876 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
878 * som.c (som_prep_for_fixups): Detect section symbols based
879 on either the lack of private data or the symbol flags. Do not
880 munge section symbol names anymore -- they no longer confuse GDB.
881 (som_begin_writing): Leave space for an exec header if writing
883 (som_slurp_symbol_table): Recognize both forms of section symbol
884 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
885 section symbols to be the name of the section they represent.
886 Debugging symbols begin with "L$0\001", not just "L$".
888 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
890 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
892 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
893 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
894 and bfd_is_local_label.
896 * targets.c: Add new entries to the bfd_target structure.
898 * bfd.c (bfd_copy_private_bfd_data): New definition.

1350 raw size of the input section.

2021 undefined, look it up in the linker hash table.
2023 * aoutx.h (translate_symbol_table): The string index 0 has a

2048 The sparc (and possibly other?) NLM format requires a different
2049 way to write exports, so add a write_export field to the backend
2050 data (and set it to NULL for everything but the sparc).
