2597 * som.c (som_begin_writing): New approach at dealing with holes
2598 in executables left by the HP linker. Does not rely on subspace
2599 alignments as subspaces are *NOT* guaranteed to be properly
2600 aligned in an executable (can you believe that!).
2602 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2604 * som.c (som_get_section_contents): New function. Do not try

2650 required by expansions. Set s and unset h when converting a reloc
2651 from undefined to section. Change handling of PC relative relocs:
2652 if against a section, they are correct in the object file, if
2653 against an external symbol they are pcrel_offset.
2654 (mips_relax_section): New function.
2655 (mips_relax_pcrel16): New function.

2740 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
2741 reloc, used in embedded PIC code.
2742 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
2743 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

2749 link_order loop. Use _bfd_generic_link_add_symbols_collect for
2750 add_symbls entry point.
2752 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
2753 counting relocs. Set SEC_RELOC flag for any section which has

2781 extended name table.
2783 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2785 Support for link_order types which generate relocs in order to
2786 support -Ur in the linker.
2787 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2788 from call to _bfd_generic_link_add_one_symbol.
2789 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2790 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2791 instead of bitsize to add_to_set call back.
2792 (_bfd_generic_final_link): Account for link_order relocs when
2793 allocating space for relocations. Handle them in link_order loop.
2794 (_bfd_generic_reloc_link_order): New function.

2811 (ecoff_bfd_final_link): Account for link_order relocs when
2812 allocating space for relocations. Handle them in link_order loop.
2813 (ecoff_link_write_external): Set the storage class of a defined
2814 linker created symbol based on the section it is in. Correct
2815 bfd_link_hash_weak case to use .sc rather than .st.
2816 (ecoff_reloc_link_order): New function.
2817 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2819 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2824 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2825 bfd_zmalloc. Free a pointer, not a union.
2826 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2828 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2830 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2832 * som.c (bfd_section_from_som_symbol): Only to do the value
2833 comparison for function symbols within executables.
2835 * som.c (bfd_section_from_som_symbol): Renamed from
2836 som_section_from_subspace_index. Pass in a native SOM symbol.
2837 For executables, iterate through the sections to find out
2838 which contains the symbol's address rather than using the
2839 symbol_info field. (symbol_info has a different meaning for
2840 dynamicly linked executables.)
2842 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2845 * som.c (som_begin_writing): Fix braino (one call to align
2846 space/subspace data was done unconditionally rather than
2847 just for executables.)
2849 * som.c (som_begin_writing): Align text in all executables to
2850 make HPUX kernel happy. Fixes strip/objcopy for shared
2853 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2855 * som.c (som_begin_writing): Account for alignment needs of
2856 subspaces too when writing executables. Never request a negative
2857 bss size. Fixes some problems with demand paged executables,
2858 still having problems with pure executables and shared executables.
2860 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2862 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2863 bfd_zalloc for rawptr, because later on we may call free, not
2866 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2867 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2868 * cisco-core.c: New file.
2869 * Makefile.in: Change accordingly.
2870 * configure.in: Recognize cisco_core_vec.
2871 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2872 * targets.c: Add cisco_core_vec.
2873 * bfd-in2.h: Rebuilt.
2875 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2877 * som.h (som_copyable_section_data_struct): New structure
2878 containing all the private section information which needs
2879 to be copied from input section to output section during
2881 (som_section_data_struct): Remove several fields now in
2882 som_copyable_section_data_struct. Make the space and
2883 subspace dictionaries be pointers (to save space when
2884 only reading objects).
2886 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2887 some references changed. Allocate a copyable data stucture if
2888 none exists. Store info into the copyable data structure.
2889 (bfd_som_set_subsection_attributes): Likewise.
2890 (som_is_space, som_is_subspace, som_is_container): New functions.
2891 Use these instead of directly accessing private data.
2892 (som_prep_headers): Allocate space and subspace headers here.
2893 Fill in some fields in the space/subspace headers from the
2895 (som_bfd_copy_private_section_data): Only copy the stuff
2896 that we really need to make objcopy and strip work. Allocate
2897 the copy_data structure for the output bfd before copying.
2899 * som.h (struct som_exec_data): New structure to hold exec
2900 info that must be preserved when running objcopy/strip.
2901 (struct somdata): Add new "exec_data" field and accessor
2902 macro. Add some comments on how the various fields are used.
2903 (som_section_data_struct): Make is_space and is_subspace bitfields.
2904 Delete unused subspace_index. All references now use the
2905 target_index field within the section structure itself.
2907 * som.c (make_unique_section): Delete unused declaration.
2908 (som_bfd_copy_private_bfd_data): New function.
2909 (som_object_setup): Allocate space for and save exec information
2910 that needs to be copied during objcopy/strip.
2911 (som_mkobject): Do not allocate space for a file header here.
2912 It is not used when only reading SOM objects.
2913 (som_prep_headers): Allocate space for and attach a file header
2914 to the output bfd. For executables, use the saved system_id
2915 value rather than trying to guess the right value. Do not abort
2916 wwhen setting file_hdr->entry* for executables.
2917 (som_begin_writing): For executables, set the exec_entry and
2919 (som_copy_private_backend_section_data): Always return a value.
2921 * libhppa.h (PA_PAGESIZE): Define.
2923 * som.c (SOM_ALIGN): Define.
2924 (som_begin_writing): If writing an executable, initialize all
2925 fields in the exec header to zero. Update fields in the exec
2926 header as sizes of loadable subspaces are computed. Carefully
2927 preserve alignments when building executables. Actually write the
2928 exec after all the fields are filled in.
2930 * Better long-filename handling. Reads SOM ABI compliant extended
2931 names, but doesn't quite write compliant extended names yet.
2932 * som.c (som_slurp_extended_name_table): Delete function. The
2933 generic code will handle things correctly.
2934 (som_slurp_armap): Seek to the beginning of the next member.
2935 (normalize): New function.
2936 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2937 name table into account when computing the file offsets in the
2938 SOM dictionary. Make sure to align to an even boundary.
2939 (som_write_armap): Initialize the checksum to zero.
2940 (ar_maxchars): Fix. Opps.
2942 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2944 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2945 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2947 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2949 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2950 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2951 * bfd-in2.h: Regenerated.
2953 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2954 this was also named trad_unix_bfd_copy_private_bfd_data.
2956 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2958 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2959 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2960 returns NULL, it is not an error. It's possible that some of
2961 these checks are not necessary (because the size can never be
2962 zero), but putting in the checks is the conservative thing to do
2963 in light of the fact that some of these malloc calls replaced
2964 unchecked alloca calls, in which a zero argument would work fine.
2966 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2968 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2969 duplicate definition.
2970 (osf_core_bfd_is_local_label): Define.
2972 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2973 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2974 failure indication, it merely means there are no relocs.
2976 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2977 after NAME, since SunOS /bin/cc can't handle it.
2979 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2981 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2982 From sukes@glue.umd.edu (Tasuki Hirata).
2984 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2986 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2987 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2988 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2990 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2992 * som.c (som_prep_for_fixups): Detect section symbols based
2993 on either the lack of private data or the symbol flags. Do not
2994 munge section symbol names anymore -- they no longer confuse GDB.
2995 (som_begin_writing): Leave space for an exec header if writing
2997 (som_slurp_symbol_table): Recognize both forms of section symbol
2998 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2999 section symbols to be the name of the section they represent.
3000 Debugging symbols begin with "L$0\001", not just "L$".
3002 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3004 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
3006 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
3007 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
3008 and bfd_is_local_label.
3010 * targets.c: Add new entries to the bfd_target structure.

3023 the target vector which all point to bfd_false.
3025 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
3026 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3027 Default new vectors for copying private backend data to bfd_true.
3028 Default new vector for determining if a symbol is a local label
3029 to bfd_generic_is_local_label.

3099 cruft (like the #pragma alloca for AIX).
3100 In addition to that problem, the C alloca calls xmalloc, which

4130 undefined, look it up in the linker hash table.
4132 * aoutx.h (translate_symbol_table): The string index 0 has a

4157 The sparc (and possibly other?) NLM format requires a different
4158 way to write exports, so add a write_export field to the backend
4159 data (and set it to NULL for everything but the sparc).
