2617 required by expansions. Set s and unset h when converting a reloc
2618 from undefined to section. Change handling of PC relative relocs:
2619 if against a section, they are correct in the object file, if
2620 against an external symbol they are pcrel_offset.
2621 (mips_relax_section): New function.
2622 (mips_relax_pcrel16): New function.

2717 add_symbls entry point.
2719 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
2720 counting relocs. Set SEC_RELOC flag for any section which has

2748 extended name table.
2750 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2752 Support for link_order types which generate relocs in order to
2753 support -Ur in the linker.
2754 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2755 from call to _bfd_generic_link_add_one_symbol.
2756 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2757 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2758 instead of bitsize to add_to_set call back.
2759 (_bfd_generic_final_link): Account for link_order relocs when
2760 allocating space for relocations. Handle them in link_order loop.
2761 (_bfd_generic_reloc_link_order): New function.

2778 (ecoff_bfd_final_link): Account for link_order relocs when
2779 allocating space for relocations. Handle them in link_order loop.
2780 (ecoff_link_write_external): Set the storage class of a defined
2781 linker created symbol based on the section it is in. Correct
2782 bfd_link_hash_weak case to use .sc rather than .st.
2783 (ecoff_reloc_link_order): New function.
2784 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2786 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2792 bfd_zmalloc. Free a pointer, not a union.
2793 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2795 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2797 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2799 * som.c (bfd_section_from_som_symbol): Only to do the value
2800 comparison for function symbols within executables.
2802 * som.c (bfd_section_from_som_symbol): Renamed from
2803 som_section_from_subspace_index. Pass in a native SOM symbol.
2804 For executables, iterate through the sections to find out
2805 which contains the symbol's address rather than using the
2806 symbol_info field. (symbol_info has a different meaning for
2807 dynamicly linked executables.)
2809 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2812 * som.c (som_begin_writing): Fix braino (one call to align
2813 space/subspace data was done unconditionally rather than
2814 just for executables.)
2816 * som.c (som_begin_writing): Align text in all executables to
2817 make HPUX kernel happy. Fixes strip/objcopy for shared
2820 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2822 * som.c (som_begin_writing): Account for alignment needs of
2823 subspaces too when writing executables. Never request a negative
2824 bss size. Fixes some problems with demand paged executables,
2825 still having problems with pure executables and shared executables.
2827 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2829 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2830 bfd_zalloc for rawptr, because later on we may call free, not
2833 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2834 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2835 * cisco-core.c: New file.

2837 * configure.in: Recognize cisco_core_vec.
2838 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.

2842 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2844 * som.h (som_copyable_section_data_struct): New structure
2845 containing all the private section information which needs
2846 to be copied from input section to output section during
2848 (som_section_data_struct): Remove several fields now in
2849 som_copyable_section_data_struct. Make the space and
2850 subspace dictionaries be pointers (to save space when
2851 only reading objects).
2853 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2854 some references changed. Allocate a copyable data stucture if
2855 none exists. Store info into the copyable data structure.
2856 (bfd_som_set_subsection_attributes): Likewise.
2857 (som_is_space, som_is_subspace, som_is_container): New functions.
2858 Use these instead of directly accessing private data.
2859 (som_prep_headers): Allocate space and subspace headers here.
2860 Fill in some fields in the space/subspace headers from the
2862 (som_bfd_copy_private_section_data): Only copy the stuff
2863 that we really need to make objcopy and strip work. Allocate
2864 the copy_data structure for the output bfd before copying.
2866 * som.h (struct som_exec_data): New structure to hold exec
2867 info that must be preserved when running objcopy/strip.
2868 (struct somdata): Add new "exec_data" field and accessor
2869 macro. Add some comments on how the various fields are used.
2870 (som_section_data_struct): Make is_space and is_subspace bitfields.
2871 Delete unused subspace_index. All references now use the
2872 target_index field within the section structure itself.
2874 * som.c (make_unique_section): Delete unused declaration.
2875 (som_bfd_copy_private_bfd_data): New function.
2876 (som_object_setup): Allocate space for and save exec information
2877 that needs to be copied during objcopy/strip.
2878 (som_mkobject): Do not allocate space for a file header here.
2879 It is not used when only reading SOM objects.
2880 (som_prep_headers): Allocate space for and attach a file header
2881 to the output bfd. For executables, use the saved system_id
2882 value rather than trying to guess the right value. Do not abort
2883 wwhen setting file_hdr->entry* for executables.
2884 (som_begin_writing): For executables, set the exec_entry and
2886 (som_copy_private_backend_section_data): Always return a value.
2888 * libhppa.h (PA_PAGESIZE): Define.
2890 * som.c (SOM_ALIGN): Define.
2891 (som_begin_writing): If writing an executable, initialize all
2892 fields in the exec header to zero. Update fields in the exec
2893 header as sizes of loadable subspaces are computed. Carefully
2894 preserve alignments when building executables. Actually write the
2895 exec after all the fields are filled in.
2897 * Better long-filename handling. Reads SOM ABI compliant extended
2898 names, but doesn't quite write compliant extended names yet.
2899 * som.c (som_slurp_extended_name_table): Delete function. The
2900 generic code will handle things correctly.
2901 (som_slurp_armap): Seek to the beginning of the next member.
2902 (normalize): New function.
2903 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2904 name table into account when computing the file offsets in the
2905 SOM dictionary. Make sure to align to an even boundary.
2906 (som_write_armap): Initialize the checksum to zero.
2907 (ar_maxchars): Fix. Opps.
2909 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2911 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2912 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2914 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2916 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2917 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2918 * bfd-in2.h: Regenerated.
2920 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2921 this was also named trad_unix_bfd_copy_private_bfd_data.
2923 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2925 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2926 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2927 returns NULL, it is not an error. It's possible that some of
2928 these checks are not necessary (because the size can never be
2929 zero), but putting in the checks is the conservative thing to do
2930 in light of the fact that some of these malloc calls replaced
2931 unchecked alloca calls, in which a zero argument would work fine.
2933 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2935 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2936 duplicate definition.
2937 (osf_core_bfd_is_local_label): Define.
2939 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2940 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2941 failure indication, it merely means there are no relocs.
2943 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2944 after NAME, since SunOS /bin/cc can't handle it.
2946 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2948 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2949 From sukes@glue.umd.edu (Tasuki Hirata).
2951 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2953 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2954 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2955 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2957 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2959 * som.c (som_prep_for_fixups): Detect section symbols based
2960 on either the lack of private data or the symbol flags. Do not
2961 munge section symbol names anymore -- they no longer confuse GDB.
2962 (som_begin_writing): Leave space for an exec header if writing
2964 (som_slurp_symbol_table): Recognize both forms of section symbol
2965 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2966 section symbols to be the name of the section they represent.
2967 Debugging symbols begin with "L$0\001", not just "L$".
2969 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2971 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2973 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2974 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2975 and bfd_is_local_label.
2977 * targets.c: Add new entries to the bfd_target structure.

2990 the target vector which all point to bfd_false.
2992 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2993 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2994 Default new vectors for copying private backend data to bfd_true.
2995 Default new vector for determining if a symbol is a local label
2996 to bfd_generic_is_local_label.
2998 * som.c (som_bfd_copy_private_section_data): New function.
2999 (som_bfd_is_local_label): New function.
3000 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
3002 * elf32-hppa.c (hppa_elf_is_local_label): New function.
3004 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3006 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3008 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3011 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3012 Indent some of them to GNU standards.
3014 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3015 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

3017 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3018 Update copyright years.
3020 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3022 * som.c (som_prep_for_fixups): A relocation involving the section
3023 symbol for the *ABS* section is really a relocation involving
3025 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3026 undefined symbols. Correctly distinguish between debugger symbols
3027 and section symbols.
3029 * som (setup_sections): Set SEC_DEBUGGING and the section attributes

3066 cruft (like the #pragma alloca for AIX).
3067 In addition to that problem, the C alloca calls xmalloc, which

4124 The sparc (and possibly other?) NLM format requires a different
4125 way to write exports, so add a write_export field to the backend
4126 data (and set it to NULL for everything but the sparc).

5262 * elfcode.h (elf_object_p): Rather than looking through an array
5263 of architectures, get the ELF EM_xxx code from the backend
5264 information. Let the generic ELF target match any EM_xxx code not
