2632 in executables left by the HP linker. Does not rely on subspace
2633 alignments as subspaces are *NOT* guaranteed to be properly

2636 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2638 * som.c (som_get_section_contents): New function. Do not try

2684 required by expansions. Set s and unset h when converting a reloc
2685 from undefined to section. Change handling of PC relative relocs:
2686 if against a section, they are correct in the object file, if
2687 against an external symbol they are pcrel_offset.
2688 (mips_relax_section): New function.
2689 (mips_relax_pcrel16): New function.

2775 reloc, used in embedded PIC code.
2776 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

2783 link_order loop. Use _bfd_generic_link_add_symbols_collect for
2784 add_symbls entry point.
2786 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
2787 counting relocs. Set SEC_RELOC flag for any section which has

2815 extended name table.
2817 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2819 Support for link_order types which generate relocs in order to
2820 support -Ur in the linker.
2821 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2822 from call to _bfd_generic_link_add_one_symbol.
2823 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2824 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2825 instead of bitsize to add_to_set call back.
2826 (_bfd_generic_final_link): Account for link_order relocs when
2827 allocating space for relocations. Handle them in link_order loop.
2828 (_bfd_generic_reloc_link_order): New function.

2845 (ecoff_bfd_final_link): Account for link_order relocs when
2846 allocating space for relocations. Handle them in link_order loop.
2847 (ecoff_link_write_external): Set the storage class of a defined
2848 linker created symbol based on the section it is in. Correct
2849 bfd_link_hash_weak case to use .sc rather than .st.
2850 (ecoff_reloc_link_order): New function.
2851 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

2862 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2864 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2866 * som.c (bfd_section_from_som_symbol): Only to do the value
2867 comparison for function symbols within executables.
2869 * som.c (bfd_section_from_som_symbol): Renamed from
2870 som_section_from_subspace_index. Pass in a native SOM symbol.
2871 For executables, iterate through the sections to find out
2872 which contains the symbol's address rather than using the
2873 symbol_info field. (symbol_info has a different meaning for
2874 dynamicly linked executables.)
2876 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2879 * som.c (som_begin_writing): Fix braino (one call to align
2880 space/subspace data was done unconditionally rather than
2881 just for executables.)
2883 * som.c (som_begin_writing): Align text in all executables to
2884 make HPUX kernel happy. Fixes strip/objcopy for shared
2887 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2889 * som.c (som_begin_writing): Account for alignment needs of
2890 subspaces too when writing executables. Never request a negative
2891 bss size. Fixes some problems with demand paged executables,
2892 still having problems with pure executables and shared executables.
2894 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2896 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2897 bfd_zalloc for rawptr, because later on we may call free, not
2900 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2901 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2902 * cisco-core.c: New file.
2903 * Makefile.in: Change accordingly.
2904 * configure.in: Recognize cisco_core_vec.
2905 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2906 * targets.c: Add cisco_core_vec.
2907 * bfd-in2.h: Rebuilt.
2909 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2911 * som.h (som_copyable_section_data_struct): New structure
2912 containing all the private section information which needs
2913 to be copied from input section to output section during
2915 (som_section_data_struct): Remove several fields now in
2916 som_copyable_section_data_struct. Make the space and
2917 subspace dictionaries be pointers (to save space when
2918 only reading objects).
2920 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2921 some references changed. Allocate a copyable data stucture if
2922 none exists. Store info into the copyable data structure.
2923 (bfd_som_set_subsection_attributes): Likewise.
2924 (som_is_space, som_is_subspace, som_is_container): New functions.
2925 Use these instead of directly accessing private data.
2926 (som_prep_headers): Allocate space and subspace headers here.
2927 Fill in some fields in the space/subspace headers from the
2929 (som_bfd_copy_private_section_data): Only copy the stuff
2930 that we really need to make objcopy and strip work. Allocate
2931 the copy_data structure for the output bfd before copying.
2933 * som.h (struct som_exec_data): New structure to hold exec
2934 info that must be preserved when running objcopy/strip.
2935 (struct somdata): Add new "exec_data" field and accessor
2936 macro. Add some comments on how the various fields are used.
2937 (som_section_data_struct): Make is_space and is_subspace bitfields.
2938 Delete unused subspace_index. All references now use the
2939 target_index field within the section structure itself.
2941 * som.c (make_unique_section): Delete unused declaration.
2942 (som_bfd_copy_private_bfd_data): New function.
2943 (som_object_setup): Allocate space for and save exec information
2944 that needs to be copied during objcopy/strip.
2945 (som_mkobject): Do not allocate space for a file header here.
2946 It is not used when only reading SOM objects.
2947 (som_prep_headers): Allocate space for and attach a file header
2948 to the output bfd. For executables, use the saved system_id
2949 value rather than trying to guess the right value. Do not abort
2950 wwhen setting file_hdr->entry* for executables.
2951 (som_begin_writing): For executables, set the exec_entry and
2953 (som_copy_private_backend_section_data): Always return a value.
2955 * libhppa.h (PA_PAGESIZE): Define.
2957 * som.c (SOM_ALIGN): Define.
2958 (som_begin_writing): If writing an executable, initialize all
2959 fields in the exec header to zero. Update fields in the exec
2960 header as sizes of loadable subspaces are computed. Carefully
2961 preserve alignments when building executables. Actually write the
2962 exec after all the fields are filled in.
2964 * Better long-filename handling. Reads SOM ABI compliant extended
2965 names, but doesn't quite write compliant extended names yet.
2966 * som.c (som_slurp_extended_name_table): Delete function. The
2967 generic code will handle things correctly.
2968 (som_slurp_armap): Seek to the beginning of the next member.
2969 (normalize): New function.
2970 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2971 name table into account when computing the file offsets in the
2972 SOM dictionary. Make sure to align to an even boundary.
2973 (som_write_armap): Initialize the checksum to zero.
2974 (ar_maxchars): Fix. Opps.
2976 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2978 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2979 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2981 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2983 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2984 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2985 * bfd-in2.h: Regenerated.
2987 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2988 this was also named trad_unix_bfd_copy_private_bfd_data.
2990 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2992 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2993 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2994 returns NULL, it is not an error. It's possible that some of
2995 these checks are not necessary (because the size can never be
2996 zero), but putting in the checks is the conservative thing to do
2997 in light of the fact that some of these malloc calls replaced
2998 unchecked alloca calls, in which a zero argument would work fine.
3000 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3002 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3003 duplicate definition.
3004 (osf_core_bfd_is_local_label): Define.
3006 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3007 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3008 failure indication, it merely means there are no relocs.
3010 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3011 after NAME, since SunOS /bin/cc can't handle it.
3013 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3015 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3016 From sukes@glue.umd.edu (Tasuki Hirata).
3018 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3020 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3021 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3022 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3024 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3026 * som.c (som_prep_for_fixups): Detect section symbols based
3027 on either the lack of private data or the symbol flags. Do not
3028 munge section symbol names anymore -- they no longer confuse GDB.

3945 bfd_coff_symname_in_debug returns true, don't put symbol name in
3946 usual string table. After writing out all symbols, if
3947 debug_string_size is not 0, check that it matches the size of the

3975 _bfd_generic_link_write_global_symbol): Don't require that all
3976 references to a common symbol be themselves common symbols.

4021 (only testing for m68k and vax at the moment); do verify that the
4022 preprocessor didn't trash the arch name inside the string version.

4053 bfd_som_set_subsection_attributes): Change parameters from char
4054 to int. Following a prototype with an old-style function definition

4161 use get_value to get the symbol value and check for undefined
4163 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4164 undefined, look it up in the linker hash table.
4166 * aoutx.h (translate_symbol_table): The string index 0 has a

4191 The sparc (and possibly other?) NLM format requires a different
4192 way to write exports, so add a write_export field to the backend
4193 data (and set it to NULL for everything but the sparc).
