2852 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2853 from call to _bfd_generic_link_add_one_symbol.
2854 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2855 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR

2857 (_bfd_generic_final_link): Account for link_order relocs when
2858 allocating space for relocations. Handle them in link_order loop.

2902 For executables, iterate through the sections to find out
2903 which contains the symbol's address rather than using the
2904 symbol_info field. (symbol_info has a different meaning for
2905 dynamicly linked executables.)
2907 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2910 * som.c (som_begin_writing): Fix braino (one call to align
2911 space/subspace data was done unconditionally rather than
2912 just for executables.)
2914 * som.c (som_begin_writing): Align text in all executables to
2915 make HPUX kernel happy. Fixes strip/objcopy for shared
2918 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2920 * som.c (som_begin_writing): Account for alignment needs of
2921 subspaces too when writing executables. Never request a negative
2922 bss size. Fixes some problems with demand paged executables,

2925 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2927 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not

2943 containing all the private section information which needs
2944 to be copied from input section to output section during
2946 (som_section_data_struct): Remove several fields now in
2947 som_copyable_section_data_struct. Make the space and
2948 subspace dictionaries be pointers (to save space when
2949 only reading objects).
2951 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2952 some references changed. Allocate a copyable data stucture if
2953 none exists. Store info into the copyable data structure.
2954 (bfd_som_set_subsection_attributes): Likewise.
2955 (som_is_space, som_is_subspace, som_is_container): New functions.
2956 Use these instead of directly accessing private data.
2957 (som_prep_headers): Allocate space and subspace headers here.
2958 Fill in some fields in the space/subspace headers from the
2960 (som_bfd_copy_private_section_data): Only copy the stuff
2961 that we really need to make objcopy and strip work. Allocate
2962 the copy_data structure for the output bfd before copying.
2964 * som.h (struct som_exec_data): New structure to hold exec
2965 info that must be preserved when running objcopy/strip.
2966 (struct somdata): Add new "exec_data" field and accessor
2967 macro. Add some comments on how the various fields are used.
2968 (som_section_data_struct): Make is_space and is_subspace bitfields.
2969 Delete unused subspace_index. All references now use the
2970 target_index field within the section structure itself.
2972 * som.c (make_unique_section): Delete unused declaration.
2973 (som_bfd_copy_private_bfd_data): New function.
2974 (som_object_setup): Allocate space for and save exec information
2975 that needs to be copied during objcopy/strip.
2976 (som_mkobject): Do not allocate space for a file header here.
2977 It is not used when only reading SOM objects.
2978 (som_prep_headers): Allocate space for and attach a file header
2979 to the output bfd. For executables, use the saved system_id
2980 value rather than trying to guess the right value. Do not abort
2981 wwhen setting file_hdr->entry* for executables.
2982 (som_begin_writing): For executables, set the exec_entry and
2984 (som_copy_private_backend_section_data): Always return a value.
2986 * libhppa.h (PA_PAGESIZE): Define.
2988 * som.c (SOM_ALIGN): Define.
2989 (som_begin_writing): If writing an executable, initialize all
2990 fields in the exec header to zero. Update fields in the exec
2991 header as sizes of loadable subspaces are computed. Carefully
2992 preserve alignments when building executables. Actually write the
2993 exec after all the fields are filled in.
2995 * Better long-filename handling. Reads SOM ABI compliant extended
2996 names, but doesn't quite write compliant extended names yet.
2997 * som.c (som_slurp_extended_name_table): Delete function. The
2998 generic code will handle things correctly.
2999 (som_slurp_armap): Seek to the beginning of the next member.
3000 (normalize): New function.
3001 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3002 name table into account when computing the file offsets in the
3003 SOM dictionary. Make sure to align to an even boundary.
3004 (som_write_armap): Initialize the checksum to zero.
3005 (ar_maxchars): Fix. Opps.

3015 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3016 * bfd-in2.h: Regenerated.
3018 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3019 this was also named trad_unix_bfd_copy_private_bfd_data.
3021 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3023 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3024 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3025 returns NULL, it is not an error. It's possible that some of
3026 these checks are not necessary (because the size can never be
3027 zero), but putting in the checks is the conservative thing to do
3028 in light of the fact that some of these malloc calls replaced
3029 unchecked alloca calls, in which a zero argument would work fine.
3031 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

3038 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3039 failure indication, it merely means there are no relocs.
3041 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3042 after NAME, since SunOS /bin/cc can't handle it.
3044 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3046 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

3051 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3052 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3053 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3055 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3057 * som.c (som_prep_for_fixups): Detect section symbols based
3058 on either the lack of private data or the symbol flags. Do not
3059 munge section symbol names anymore -- they no longer confuse GDB.

3062 (som_slurp_symbol_table): Recognize both forms of section symbol
3063 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3064 section symbols to be the name of the section they represent.
3065 Debugging symbols begin with "L$0\001", not just "L$".

3120 * som.c (som_prep_for_fixups): A relocation involving the section
3121 symbol for the *ABS* section is really a relocation involving
3123 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3124 undefined symbols. Correctly distinguish between debugger symbols
3125 and section symbols.
3127 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3128 for spaces and subspaces.
3130 * som.c (som_bfd_count_ar_symbols): Fix typo.
3132 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3133 HAS_RELOC based on the object's magic number.

3135 prepared to handle multiple sections with the same name.
3136 (setup_sections): Allocate space on the BFD's obstack to hold
3137 section names. Use bfd_make_setion_anyway rather than the

3164 cruft (like the #pragma alloca for AIX).
3165 In addition to that problem, the C alloca calls xmalloc, which
3166 means checking for being out of memory can't work right. The
3167 following changes remove all uses of alloca from BFD.
3168 * hosts/solaris2.h: Remove alloca cruft.
3169 * som.c: Replace alloca with a fixed size auto array.

3210 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3211 include it in elf32-hppa.h.
3213 * som.c (log2): Return -1 on error rather than aborting.
3214 (setup_sections): Bubble up an error from log2.
3216 * Changes to make HP C compiler happy in both traditional
3218 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

3221 unsigned char to avoid GNU-C extensions.
3222 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3223 or failure rather than aborting on failure.
3225 * som.h (bfd_som_set_section_attributes): Fix prototype to match

3293 linker stubs into a single function (so they can easily share a
3294 ton of common code).

3342 COMPLEX relocation support (it's never used anyway).
3343 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

3502 Tue Feb 15 19:39:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3504 * section.c (bfd_get_section_contents): Since this function reads
3505 unrelocated contents, the section's raw size is always the one to
3506 use for bounds checking.
3508 * linker.c (default_indirect_link_order): In assertion, compare
3509 link_order size field against cooked size, not raw size, of input
3512 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
3514 (aligncode): When shrinking, the addend should be set to the
3515 current offset in the section plus the number of bytes of padding
3516 that will actually be retained.
3517 (b_out_relax_section): If a section contains no relocations, don't
3518 bother processing them.
3519 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3522 (b_out_get_relocated_section_contents, case ALIGNDONE): Assert
3523 that reloc->addend falls between the current source offset and the
3524 raw size of the input section.
3526 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
3527 bout. Default with no version number is still bout. Support

4084 bfd_som_set_subsection_attributes): Change parameters from char
4085 to int. Following a prototype with an old-style function definition

4192 use get_value to get the symbol value and check for undefined
4194 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4195 undefined, look it up in the linker hash table.
4197 * aoutx.h (translate_symbol_table): The string index 0 has a

4222 The sparc (and possibly other?) NLM format requires a different
4223 way to write exports, so add a write_export field to the backend
4224 data (and set it to NULL for everything but the sparc).
