2635 in executables left by the HP linker. Does not rely on subspace
2636 alignments as subspaces are *NOT* guaranteed to be properly

2688 from undefined to section. Change handling of PC relative relocs:
2689 if against a section, they are correct in the object file, if
2690 against an external symbol they are pcrel_offset.
2691 (mips_relax_section): New function.
2692 (mips_relax_pcrel16): New function.

2818 extended name table.
2820 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2822 Support for link_order types which generate relocs in order to
2823 support -Ur in the linker.
2824 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2825 from call to _bfd_generic_link_add_one_symbol.
2826 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2827 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2828 instead of bitsize to add_to_set call back.
2829 (_bfd_generic_final_link): Account for link_order relocs when
2830 allocating space for relocations. Handle them in link_order loop.

2849 allocating space for relocations. Handle them in link_order loop.
2850 (ecoff_link_write_external): Set the storage class of a defined
2851 linker created symbol based on the section it is in. Correct
2852 bfd_link_hash_weak case to use .sc rather than .st.
2853 (ecoff_reloc_link_order): New function.
2854 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

2865 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2867 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2869 * som.c (bfd_section_from_som_symbol): Only to do the value
2870 comparison for function symbols within executables.
2872 * som.c (bfd_section_from_som_symbol): Renamed from
2873 som_section_from_subspace_index. Pass in a native SOM symbol.
2874 For executables, iterate through the sections to find out
2875 which contains the symbol's address rather than using the
2876 symbol_info field. (symbol_info has a different meaning for
2877 dynamicly linked executables.)
2879 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2882 * som.c (som_begin_writing): Fix braino (one call to align
2883 space/subspace data was done unconditionally rather than
2884 just for executables.)
2886 * som.c (som_begin_writing): Align text in all executables to
2887 make HPUX kernel happy. Fixes strip/objcopy for shared
2890 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2892 * som.c (som_begin_writing): Account for alignment needs of
2893 subspaces too when writing executables. Never request a negative
2894 bss size. Fixes some problems with demand paged executables,
2895 still having problems with pure executables and shared executables.
2897 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2899 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2900 bfd_zalloc for rawptr, because later on we may call free, not
2903 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2904 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2905 * cisco-core.c: New file.

2907 * configure.in: Recognize cisco_core_vec.
2908 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2909 * targets.c: Add cisco_core_vec.

2912 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2914 * som.h (som_copyable_section_data_struct): New structure
2915 containing all the private section information which needs
2916 to be copied from input section to output section during
2918 (som_section_data_struct): Remove several fields now in
2919 som_copyable_section_data_struct. Make the space and
2920 subspace dictionaries be pointers (to save space when
2921 only reading objects).
2923 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2924 some references changed. Allocate a copyable data stucture if
2925 none exists. Store info into the copyable data structure.
2926 (bfd_som_set_subsection_attributes): Likewise.
2927 (som_is_space, som_is_subspace, som_is_container): New functions.
2928 Use these instead of directly accessing private data.
2929 (som_prep_headers): Allocate space and subspace headers here.
2930 Fill in some fields in the space/subspace headers from the
2932 (som_bfd_copy_private_section_data): Only copy the stuff
2933 that we really need to make objcopy and strip work. Allocate
2934 the copy_data structure for the output bfd before copying.
2936 * som.h (struct som_exec_data): New structure to hold exec
2937 info that must be preserved when running objcopy/strip.
2938 (struct somdata): Add new "exec_data" field and accessor
2939 macro. Add some comments on how the various fields are used.
2940 (som_section_data_struct): Make is_space and is_subspace bitfields.
2941 Delete unused subspace_index. All references now use the
2942 target_index field within the section structure itself.
2944 * som.c (make_unique_section): Delete unused declaration.
2945 (som_bfd_copy_private_bfd_data): New function.
2946 (som_object_setup): Allocate space for and save exec information
2947 that needs to be copied during objcopy/strip.
2948 (som_mkobject): Do not allocate space for a file header here.
2949 It is not used when only reading SOM objects.
2950 (som_prep_headers): Allocate space for and attach a file header
2951 to the output bfd. For executables, use the saved system_id
2952 value rather than trying to guess the right value. Do not abort
2953 wwhen setting file_hdr->entry* for executables.
2954 (som_begin_writing): For executables, set the exec_entry and
2956 (som_copy_private_backend_section_data): Always return a value.
2958 * libhppa.h (PA_PAGESIZE): Define.
2960 * som.c (SOM_ALIGN): Define.
2961 (som_begin_writing): If writing an executable, initialize all
2962 fields in the exec header to zero. Update fields in the exec
2963 header as sizes of loadable subspaces are computed. Carefully
2964 preserve alignments when building executables. Actually write the
2965 exec after all the fields are filled in.
2967 * Better long-filename handling. Reads SOM ABI compliant extended
2968 names, but doesn't quite write compliant extended names yet.
2969 * som.c (som_slurp_extended_name_table): Delete function. The
2970 generic code will handle things correctly.
2971 (som_slurp_armap): Seek to the beginning of the next member.
2972 (normalize): New function.
2973 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2974 name table into account when computing the file offsets in the
2975 SOM dictionary. Make sure to align to an even boundary.
2976 (som_write_armap): Initialize the checksum to zero.
2977 (ar_maxchars): Fix. Opps.
2979 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2981 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2982 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2984 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2986 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2987 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2988 * bfd-in2.h: Regenerated.
2990 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2991 this was also named trad_unix_bfd_copy_private_bfd_data.
2993 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2995 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2996 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2997 returns NULL, it is not an error. It's possible that some of
2998 these checks are not necessary (because the size can never be
2999 zero), but putting in the checks is the conservative thing to do
3000 in light of the fact that some of these malloc calls replaced
3001 unchecked alloca calls, in which a zero argument would work fine.
3003 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3005 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3006 duplicate definition.
3007 (osf_core_bfd_is_local_label): Define.
3009 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3010 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3011 failure indication, it merely means there are no relocs.
3013 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3014 after NAME, since SunOS /bin/cc can't handle it.
3016 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3018 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3019 From sukes@glue.umd.edu (Tasuki Hirata).
3021 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3023 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3024 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3025 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).

3092 * som.c (som_prep_for_fixups): A relocation involving the section
3093 symbol for the *ABS* section is really a relocation involving
3095 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for

3136 cruft (like the #pragma alloca for AIX).
3137 In addition to that problem, the C alloca calls xmalloc, which

3978 _bfd_generic_link_write_global_symbol): Don't require that all
3979 references to a common symbol be themselves common symbols.

4056 bfd_som_set_subsection_attributes): Change parameters from char
4057 to int. Following a prototype with an old-style function definition

4164 use get_value to get the symbol value and check for undefined
4166 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4167 undefined, look it up in the linker hash table.
4169 * aoutx.h (translate_symbol_table): The string index 0 has a

4194 The sparc (and possibly other?) NLM format requires a different
4195 way to write exports, so add a write_export field to the backend
4196 data (and set it to NULL for everything but the sparc).
