2850 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2851 from call to _bfd_generic_link_add_one_symbol.
2852 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2853 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2854 instead of bitsize to add_to_set call back.
2855 (_bfd_generic_final_link): Account for link_order relocs when
2856 allocating space for relocations. Handle them in link_order loop.

2900 For executables, iterate through the sections to find out
2901 which contains the symbol's address rather than using the
2902 symbol_info field. (symbol_info has a different meaning for
2903 dynamicly linked executables.)
2905 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2908 * som.c (som_begin_writing): Fix braino (one call to align
2909 space/subspace data was done unconditionally rather than
2910 just for executables.)
2912 * som.c (som_begin_writing): Align text in all executables to
2913 make HPUX kernel happy. Fixes strip/objcopy for shared
2916 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2918 * som.c (som_begin_writing): Account for alignment needs of
2919 subspaces too when writing executables. Never request a negative
2920 bss size. Fixes some problems with demand paged executables,
2921 still having problems with pure executables and shared executables.
2923 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2925 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not

2941 containing all the private section information which needs
2942 to be copied from input section to output section during
2944 (som_section_data_struct): Remove several fields now in
2945 som_copyable_section_data_struct. Make the space and
2946 subspace dictionaries be pointers (to save space when
2947 only reading objects).
2949 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2950 some references changed. Allocate a copyable data stucture if
2951 none exists. Store info into the copyable data structure.
2952 (bfd_som_set_subsection_attributes): Likewise.
2953 (som_is_space, som_is_subspace, som_is_container): New functions.
2954 Use these instead of directly accessing private data.
2955 (som_prep_headers): Allocate space and subspace headers here.
2956 Fill in some fields in the space/subspace headers from the
2958 (som_bfd_copy_private_section_data): Only copy the stuff
2959 that we really need to make objcopy and strip work. Allocate
2960 the copy_data structure for the output bfd before copying.
2962 * som.h (struct som_exec_data): New structure to hold exec
2963 info that must be preserved when running objcopy/strip.
2964 (struct somdata): Add new "exec_data" field and accessor
2965 macro. Add some comments on how the various fields are used.
2966 (som_section_data_struct): Make is_space and is_subspace bitfields.
2967 Delete unused subspace_index. All references now use the
2968 target_index field within the section structure itself.
2970 * som.c (make_unique_section): Delete unused declaration.
2971 (som_bfd_copy_private_bfd_data): New function.
2972 (som_object_setup): Allocate space for and save exec information
2973 that needs to be copied during objcopy/strip.
2974 (som_mkobject): Do not allocate space for a file header here.
2975 It is not used when only reading SOM objects.
2976 (som_prep_headers): Allocate space for and attach a file header
2977 to the output bfd. For executables, use the saved system_id
2978 value rather than trying to guess the right value. Do not abort
2979 wwhen setting file_hdr->entry* for executables.
2980 (som_begin_writing): For executables, set the exec_entry and
2982 (som_copy_private_backend_section_data): Always return a value.
2984 * libhppa.h (PA_PAGESIZE): Define.
2986 * som.c (SOM_ALIGN): Define.
2987 (som_begin_writing): If writing an executable, initialize all
2988 fields in the exec header to zero. Update fields in the exec
2989 header as sizes of loadable subspaces are computed. Carefully
2990 preserve alignments when building executables. Actually write the
2991 exec after all the fields are filled in.
2993 * Better long-filename handling. Reads SOM ABI compliant extended
2994 names, but doesn't quite write compliant extended names yet.
2995 * som.c (som_slurp_extended_name_table): Delete function. The
2996 generic code will handle things correctly.
2997 (som_slurp_armap): Seek to the beginning of the next member.
2998 (normalize): New function.
2999 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3000 name table into account when computing the file offsets in the
3001 SOM dictionary. Make sure to align to an even boundary.
3002 (som_write_armap): Initialize the checksum to zero.
3003 (ar_maxchars): Fix. Opps.

3013 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3014 * bfd-in2.h: Regenerated.
3016 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3017 this was also named trad_unix_bfd_copy_private_bfd_data.
3019 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3021 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3022 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3023 returns NULL, it is not an error. It's possible that some of
3024 these checks are not necessary (because the size can never be
3025 zero), but putting in the checks is the conservative thing to do
3026 in light of the fact that some of these malloc calls replaced
3027 unchecked alloca calls, in which a zero argument would work fine.
3029 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

3036 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3037 failure indication, it merely means there are no relocs.
3039 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3040 after NAME, since SunOS /bin/cc can't handle it.
3042 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3044 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

3049 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3050 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3051 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3053 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3055 * som.c (som_prep_for_fixups): Detect section symbols based
3056 on either the lack of private data or the symbol flags. Do not
3057 munge section symbol names anymore -- they no longer confuse GDB.

3060 (som_slurp_symbol_table): Recognize both forms of section symbol
3061 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3062 section symbols to be the name of the section they represent.
3063 Debugging symbols begin with "L$0\001", not just "L$".

3118 * som.c (som_prep_for_fixups): A relocation involving the section
3119 symbol for the *ABS* section is really a relocation involving
3121 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3122 undefined symbols. Correctly distinguish between debugger symbols
3123 and section symbols.
3125 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3126 for spaces and subspaces.
3128 * som.c (som_bfd_count_ar_symbols): Fix typo.

3133 prepared to handle multiple sections with the same name.
3134 (setup_sections): Allocate space on the BFD's obstack to hold
3135 section names. Use bfd_make_setion_anyway rather than the

3162 cruft (like the #pragma alloca for AIX).
3163 In addition to that problem, the C alloca calls xmalloc, which
3164 means checking for being out of memory can't work right. The
3165 following changes remove all uses of alloca from BFD.

3208 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3209 include it in elf32-hppa.h.
3211 * som.c (log2): Return -1 on error rather than aborting.
3212 (setup_sections): Bubble up an error from log2.
3214 * Changes to make HP C compiler happy in both traditional
3216 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

3219 unsigned char to avoid GNU-C extensions.
3220 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3221 or failure rather than aborting on failure.
3223 * som.h (bfd_som_set_section_attributes): Fix prototype to match

3291 linker stubs into a single function (so they can easily share a
3292 ton of common code).

3340 COMPLEX relocation support (it's never used anyway).
3341 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

3500 Tue Feb 15 19:39:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3502 * section.c (bfd_get_section_contents): Since this function reads
3503 unrelocated contents, the section's raw size is always the one to
3504 use for bounds checking.
3506 * linker.c (default_indirect_link_order): In assertion, compare
3507 link_order size field against cooked size, not raw size, of input
3510 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
3512 (aligncode): When shrinking, the addend should be set to the
3513 current offset in the section plus the number of bytes of padding
3514 that will actually be retained.
3515 (b_out_relax_section): If a section contains no relocations, don't
3516 bother processing them.
3517 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3521 that reloc->addend falls between the current source offset and the
3522 raw size of the input section.
3524 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
3525 bout. Default with no version number is still bout. Support

4082 bfd_som_set_subsection_attributes): Change parameters from char
4083 to int. Following a prototype with an old-style function definition

4193 undefined, look it up in the linker hash table.
4195 * aoutx.h (translate_symbol_table): The string index 0 has a

4220 The sparc (and possibly other?) NLM format requires a different
4221 way to write exports, so add a write_export field to the backend
4222 data (and set it to NULL for everything but the sparc).
