2628 required by expansions. Set s and unset h when converting a reloc
2629 from undefined to section. Change handling of PC relative relocs:
2630 if against a section, they are correct in the object file, if
2631 against an external symbol they are pcrel_offset.
2632 (mips_relax_section): New function.
2633 (mips_relax_pcrel16): New function.

2759 extended name table.
2761 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2763 Support for link_order types which generate relocs in order to
2764 support -Ur in the linker.
2765 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2766 from call to _bfd_generic_link_add_one_symbol.
2767 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2768 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2769 instead of bitsize to add_to_set call back.
2770 (_bfd_generic_final_link): Account for link_order relocs when
2771 allocating space for relocations. Handle them in link_order loop.
2772 (_bfd_generic_reloc_link_order): New function.

2789 (ecoff_bfd_final_link): Account for link_order relocs when
2790 allocating space for relocations. Handle them in link_order loop.
2791 (ecoff_link_write_external): Set the storage class of a defined
2792 linker created symbol based on the section it is in. Correct
2793 bfd_link_hash_weak case to use .sc rather than .st.
2794 (ecoff_reloc_link_order): New function.
2795 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2797 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2802 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2803 bfd_zmalloc. Free a pointer, not a union.
2804 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2806 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2808 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2810 * som.c (bfd_section_from_som_symbol): Only to do the value
2811 comparison for function symbols within executables.
2813 * som.c (bfd_section_from_som_symbol): Renamed from
2814 som_section_from_subspace_index. Pass in a native SOM symbol.
2815 For executables, iterate through the sections to find out
2816 which contains the symbol's address rather than using the
2817 symbol_info field. (symbol_info has a different meaning for
2818 dynamicly linked executables.)
2820 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2823 * som.c (som_begin_writing): Fix braino (one call to align
2824 space/subspace data was done unconditionally rather than
2825 just for executables.)
2827 * som.c (som_begin_writing): Align text in all executables to
2828 make HPUX kernel happy. Fixes strip/objcopy for shared
2831 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2833 * som.c (som_begin_writing): Account for alignment needs of
2834 subspaces too when writing executables. Never request a negative
2835 bss size. Fixes some problems with demand paged executables,
2836 still having problems with pure executables and shared executables.
2838 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2840 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2841 bfd_zalloc for rawptr, because later on we may call free, not
2844 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2845 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2846 * cisco-core.c: New file.
2847 * Makefile.in: Change accordingly.
2848 * configure.in: Recognize cisco_core_vec.
2849 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.

2853 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2855 * som.h (som_copyable_section_data_struct): New structure
2856 containing all the private section information which needs
2857 to be copied from input section to output section during
2859 (som_section_data_struct): Remove several fields now in
2860 som_copyable_section_data_struct. Make the space and
2861 subspace dictionaries be pointers (to save space when
2862 only reading objects).
2864 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2865 some references changed. Allocate a copyable data stucture if
2866 none exists. Store info into the copyable data structure.
2867 (bfd_som_set_subsection_attributes): Likewise.
2868 (som_is_space, som_is_subspace, som_is_container): New functions.
2869 Use these instead of directly accessing private data.
2870 (som_prep_headers): Allocate space and subspace headers here.
2871 Fill in some fields in the space/subspace headers from the
2873 (som_bfd_copy_private_section_data): Only copy the stuff
2874 that we really need to make objcopy and strip work. Allocate
2875 the copy_data structure for the output bfd before copying.
2877 * som.h (struct som_exec_data): New structure to hold exec
2878 info that must be preserved when running objcopy/strip.
2879 (struct somdata): Add new "exec_data" field and accessor
2880 macro. Add some comments on how the various fields are used.
2881 (som_section_data_struct): Make is_space and is_subspace bitfields.
2882 Delete unused subspace_index. All references now use the
2883 target_index field within the section structure itself.
2885 * som.c (make_unique_section): Delete unused declaration.
2886 (som_bfd_copy_private_bfd_data): New function.
2887 (som_object_setup): Allocate space for and save exec information
2888 that needs to be copied during objcopy/strip.
2889 (som_mkobject): Do not allocate space for a file header here.
2890 It is not used when only reading SOM objects.
2891 (som_prep_headers): Allocate space for and attach a file header
2892 to the output bfd. For executables, use the saved system_id
2893 value rather than trying to guess the right value. Do not abort
2894 wwhen setting file_hdr->entry* for executables.
2895 (som_begin_writing): For executables, set the exec_entry and
2897 (som_copy_private_backend_section_data): Always return a value.
2899 * libhppa.h (PA_PAGESIZE): Define.
2901 * som.c (SOM_ALIGN): Define.
2902 (som_begin_writing): If writing an executable, initialize all
2903 fields in the exec header to zero. Update fields in the exec
2904 header as sizes of loadable subspaces are computed. Carefully
2905 preserve alignments when building executables. Actually write the
2906 exec after all the fields are filled in.
2908 * Better long-filename handling. Reads SOM ABI compliant extended
2909 names, but doesn't quite write compliant extended names yet.
2910 * som.c (som_slurp_extended_name_table): Delete function. The
2911 generic code will handle things correctly.
2912 (som_slurp_armap): Seek to the beginning of the next member.
2913 (normalize): New function.
2914 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2915 name table into account when computing the file offsets in the
2916 SOM dictionary. Make sure to align to an even boundary.
2917 (som_write_armap): Initialize the checksum to zero.
2918 (ar_maxchars): Fix. Opps.
2920 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2922 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2923 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2925 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2927 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2928 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2929 * bfd-in2.h: Regenerated.
2931 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2932 this was also named trad_unix_bfd_copy_private_bfd_data.
2934 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2936 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2937 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2938 returns NULL, it is not an error. It's possible that some of
2939 these checks are not necessary (because the size can never be
2940 zero), but putting in the checks is the conservative thing to do
2941 in light of the fact that some of these malloc calls replaced
2942 unchecked alloca calls, in which a zero argument would work fine.
2944 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2946 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2947 duplicate definition.
2948 (osf_core_bfd_is_local_label): Define.
2950 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2951 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2952 failure indication, it merely means there are no relocs.
2954 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2955 after NAME, since SunOS /bin/cc can't handle it.
2957 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2959 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2960 From sukes@glue.umd.edu (Tasuki Hirata).
2962 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2964 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2965 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2966 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2968 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2970 * som.c (som_prep_for_fixups): Detect section symbols based
2971 on either the lack of private data or the symbol flags. Do not
2972 munge section symbol names anymore -- they no longer confuse GDB.
2973 (som_begin_writing): Leave space for an exec header if writing
2975 (som_slurp_symbol_table): Recognize both forms of section symbol
2976 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2977 section symbols to be the name of the section they represent.
2978 Debugging symbols begin with "L$0\001", not just "L$".
2980 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2982 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2984 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2985 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2986 and bfd_is_local_label.
2988 * targets.c: Add new entries to the bfd_target structure.
2990 * bfd.c (bfd_copy_private_bfd_data): New definition.

3001 the target vector which all point to bfd_false.
3003 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3004 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3005 Default new vectors for copying private backend data to bfd_true.
3006 Default new vector for determining if a symbol is a local label
3007 to bfd_generic_is_local_label.
3009 * som.c (som_bfd_copy_private_section_data): New function.
3010 (som_bfd_is_local_label): New function.
3011 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3013 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3015 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3017 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3019 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3022 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3023 Indent some of them to GNU standards.
3025 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3026 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

3037 undefined symbols. Correctly distinguish between debugger symbols
3038 and section symbols.

3041 for spaces and subspaces.
3043 * som.c (som_bfd_count_ar_symbols): Fix typo.

3077 cruft (like the #pragma alloca for AIX).
3078 In addition to that problem, the C alloca calls xmalloc, which

4135 The sparc (and possibly other?) NLM format requires a different
4136 way to write exports, so add a write_export field to the backend
4137 data (and set it to NULL for everything but the sparc).
