2831 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2832 from call to _bfd_generic_link_add_one_symbol.
2833 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2834 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2835 instead of bitsize to add_to_set call back.
2836 (_bfd_generic_final_link): Account for link_order relocs when
2837 allocating space for relocations. Handle them in link_order loop.

2881 For executables, iterate through the sections to find out
2882 which contains the symbol's address rather than using the
2883 symbol_info field. (symbol_info has a different meaning for
2884 dynamicly linked executables.)
2886 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2889 * som.c (som_begin_writing): Fix braino (one call to align
2890 space/subspace data was done unconditionally rather than
2891 just for executables.)
2893 * som.c (som_begin_writing): Align text in all executables to
2894 make HPUX kernel happy. Fixes strip/objcopy for shared
2897 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2899 * som.c (som_begin_writing): Account for alignment needs of
2900 subspaces too when writing executables. Never request a negative
2901 bss size. Fixes some problems with demand paged executables,
2902 still having problems with pure executables and shared executables.
2904 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2906 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2907 bfd_zalloc for rawptr, because later on we may call free, not
2910 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2911 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.

2921 * som.h (som_copyable_section_data_struct): New structure
2922 containing all the private section information which needs
2923 to be copied from input section to output section during
2925 (som_section_data_struct): Remove several fields now in
2926 som_copyable_section_data_struct. Make the space and
2927 subspace dictionaries be pointers (to save space when
2928 only reading objects).
2930 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2931 some references changed. Allocate a copyable data stucture if
2932 none exists. Store info into the copyable data structure.
2933 (bfd_som_set_subsection_attributes): Likewise.
2934 (som_is_space, som_is_subspace, som_is_container): New functions.
2935 Use these instead of directly accessing private data.
2936 (som_prep_headers): Allocate space and subspace headers here.
2937 Fill in some fields in the space/subspace headers from the
2939 (som_bfd_copy_private_section_data): Only copy the stuff
2940 that we really need to make objcopy and strip work. Allocate
2941 the copy_data structure for the output bfd before copying.
2943 * som.h (struct som_exec_data): New structure to hold exec
2944 info that must be preserved when running objcopy/strip.
2945 (struct somdata): Add new "exec_data" field and accessor
2946 macro. Add some comments on how the various fields are used.
2947 (som_section_data_struct): Make is_space and is_subspace bitfields.
2948 Delete unused subspace_index. All references now use the
2949 target_index field within the section structure itself.
2951 * som.c (make_unique_section): Delete unused declaration.
2952 (som_bfd_copy_private_bfd_data): New function.
2953 (som_object_setup): Allocate space for and save exec information
2954 that needs to be copied during objcopy/strip.
2955 (som_mkobject): Do not allocate space for a file header here.
2956 It is not used when only reading SOM objects.
2957 (som_prep_headers): Allocate space for and attach a file header
2958 to the output bfd. For executables, use the saved system_id
2959 value rather than trying to guess the right value. Do not abort
2960 wwhen setting file_hdr->entry* for executables.
2961 (som_begin_writing): For executables, set the exec_entry and
2963 (som_copy_private_backend_section_data): Always return a value.
2965 * libhppa.h (PA_PAGESIZE): Define.
2967 * som.c (SOM_ALIGN): Define.
2968 (som_begin_writing): If writing an executable, initialize all
2969 fields in the exec header to zero. Update fields in the exec
2970 header as sizes of loadable subspaces are computed. Carefully
2971 preserve alignments when building executables. Actually write the
2972 exec after all the fields are filled in.
2974 * Better long-filename handling. Reads SOM ABI compliant extended
2975 names, but doesn't quite write compliant extended names yet.
2976 * som.c (som_slurp_extended_name_table): Delete function. The
2977 generic code will handle things correctly.
2978 (som_slurp_armap): Seek to the beginning of the next member.
2979 (normalize): New function.
2980 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2981 name table into account when computing the file offsets in the
2982 SOM dictionary. Make sure to align to an even boundary.
2983 (som_write_armap): Initialize the checksum to zero.
2984 (ar_maxchars): Fix. Opps.

2988 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2989 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2991 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2993 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2994 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2995 * bfd-in2.h: Regenerated.
2997 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2998 this was also named trad_unix_bfd_copy_private_bfd_data.
3000 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3002 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3003 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3004 returns NULL, it is not an error. It's possible that some of
3005 these checks are not necessary (because the size can never be
3006 zero), but putting in the checks is the conservative thing to do
3007 in light of the fact that some of these malloc calls replaced
3008 unchecked alloca calls, in which a zero argument would work fine.
3010 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3012 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3013 duplicate definition.
3014 (osf_core_bfd_is_local_label): Define.
3016 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3017 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3018 failure indication, it merely means there are no relocs.
3020 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3021 after NAME, since SunOS /bin/cc can't handle it.
3023 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3025 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3026 From sukes@glue.umd.edu (Tasuki Hirata).

3030 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3031 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3032 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3034 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3036 * som.c (som_prep_for_fixups): Detect section symbols based

3099 * som.c (som_prep_for_fixups): A relocation involving the section
3100 symbol for the *ABS* section is really a relocation involving
3102 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3103 undefined symbols. Correctly distinguish between debugger symbols
3104 and section symbols.

3107 for spaces and subspaces.
3109 * som.c (som_bfd_count_ar_symbols): Fix typo.

3143 cruft (like the #pragma alloca for AIX).
3144 In addition to that problem, the C alloca calls xmalloc, which
3145 means checking for being out of memory can't work right. The
3146 following changes remove all uses of alloca from BFD.

3189 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3190 include it in elf32-hppa.h.
3192 * som.c (log2): Return -1 on error rather than aborting.
3193 (setup_sections): Bubble up an error from log2.
3195 * Changes to make HP C compiler happy in both traditional
3197 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

3202 or failure rather than aborting on failure.
3204 * som.h (bfd_som_set_section_attributes): Fix prototype to match

3272 linker stubs into a single function (so they can easily share a
3273 ton of common code).

3483 * section.c (bfd_get_section_contents): Since this function reads
3484 unrelocated contents, the section's raw size is always the one to

3494 current offset in the section plus the number of bytes of padding
3495 that will actually be retained.
3496 (b_out_relax_section): If a section contains no relocations, don't
3497 bother processing them.
3498 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3502 that reloc->addend falls between the current source offset and the
3503 raw size of the input section.

3985 _bfd_generic_link_write_global_symbol): Don't require that all
3986 references to a common symbol be themselves common symbols.

4031 (only testing for m68k and vax at the moment); do verify that the
4032 preprocessor didn't trash the arch name inside the string version.

4063 bfd_som_set_subsection_attributes): Change parameters from char
4064 to int. Following a prototype with an old-style function definition

4171 use get_value to get the symbol value and check for undefined
4173 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4174 undefined, look it up in the linker hash table.
4176 * aoutx.h (translate_symbol_table): The string index 0 has a

4201 The sparc (and possibly other?) NLM format requires a different
4202 way to write exports, so add a write_export field to the backend
4203 data (and set it to NULL for everything but the sparc).
