2848 from call to _bfd_generic_link_add_one_symbol.
2849 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2850 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR

2897 For executables, iterate through the sections to find out
2898 which contains the symbol's address rather than using the
2899 symbol_info field. (symbol_info has a different meaning for
2900 dynamicly linked executables.)
2902 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2905 * som.c (som_begin_writing): Fix braino (one call to align
2906 space/subspace data was done unconditionally rather than
2907 just for executables.)
2909 * som.c (som_begin_writing): Align text in all executables to
2910 make HPUX kernel happy. Fixes strip/objcopy for shared
2913 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2915 * som.c (som_begin_writing): Account for alignment needs of
2916 subspaces too when writing executables. Never request a negative
2917 bss size. Fixes some problems with demand paged executables,

2920 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2922 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not

2938 containing all the private section information which needs
2939 to be copied from input section to output section during
2941 (som_section_data_struct): Remove several fields now in
2942 som_copyable_section_data_struct. Make the space and
2943 subspace dictionaries be pointers (to save space when
2944 only reading objects).
2946 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2947 some references changed. Allocate a copyable data stucture if
2948 none exists. Store info into the copyable data structure.
2949 (bfd_som_set_subsection_attributes): Likewise.
2950 (som_is_space, som_is_subspace, som_is_container): New functions.
2951 Use these instead of directly accessing private data.
2952 (som_prep_headers): Allocate space and subspace headers here.
2953 Fill in some fields in the space/subspace headers from the
2955 (som_bfd_copy_private_section_data): Only copy the stuff
2956 that we really need to make objcopy and strip work. Allocate
2957 the copy_data structure for the output bfd before copying.
2959 * som.h (struct som_exec_data): New structure to hold exec
2960 info that must be preserved when running objcopy/strip.
2961 (struct somdata): Add new "exec_data" field and accessor
2962 macro. Add some comments on how the various fields are used.
2963 (som_section_data_struct): Make is_space and is_subspace bitfields.
2964 Delete unused subspace_index. All references now use the
2965 target_index field within the section structure itself.
2967 * som.c (make_unique_section): Delete unused declaration.
2968 (som_bfd_copy_private_bfd_data): New function.
2969 (som_object_setup): Allocate space for and save exec information
2970 that needs to be copied during objcopy/strip.
2971 (som_mkobject): Do not allocate space for a file header here.
2972 It is not used when only reading SOM objects.
2973 (som_prep_headers): Allocate space for and attach a file header
2974 to the output bfd. For executables, use the saved system_id
2975 value rather than trying to guess the right value. Do not abort
2976 wwhen setting file_hdr->entry* for executables.
2977 (som_begin_writing): For executables, set the exec_entry and
2979 (som_copy_private_backend_section_data): Always return a value.
2981 * libhppa.h (PA_PAGESIZE): Define.
2983 * som.c (SOM_ALIGN): Define.
2984 (som_begin_writing): If writing an executable, initialize all
2985 fields in the exec header to zero. Update fields in the exec
2986 header as sizes of loadable subspaces are computed. Carefully
2987 preserve alignments when building executables. Actually write the
2988 exec after all the fields are filled in.
2990 * Better long-filename handling. Reads SOM ABI compliant extended
2991 names, but doesn't quite write compliant extended names yet.
2992 * som.c (som_slurp_extended_name_table): Delete function. The
2993 generic code will handle things correctly.
2994 (som_slurp_armap): Seek to the beginning of the next member.
2995 (normalize): New function.
2996 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2997 name table into account when computing the file offsets in the
2998 SOM dictionary. Make sure to align to an even boundary.
2999 (som_write_armap): Initialize the checksum to zero.
3000 (ar_maxchars): Fix. Opps.

3010 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
3011 * bfd-in2.h: Regenerated.
3013 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3014 this was also named trad_unix_bfd_copy_private_bfd_data.
3016 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3018 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3019 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3020 returns NULL, it is not an error. It's possible that some of
3021 these checks are not necessary (because the size can never be
3022 zero), but putting in the checks is the conservative thing to do
3023 in light of the fact that some of these malloc calls replaced
3024 unchecked alloca calls, in which a zero argument would work fine.
3026 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3028 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove

3032 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3033 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3034 failure indication, it merely means there are no relocs.
3036 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3037 after NAME, since SunOS /bin/cc can't handle it.
3039 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3041 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

3046 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3047 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3048 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3050 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3052 * som.c (som_prep_for_fixups): Detect section symbols based
3053 on either the lack of private data or the symbol flags. Do not
3054 munge section symbol names anymore -- they no longer confuse GDB.

3057 (som_slurp_symbol_table): Recognize both forms of section symbol
3058 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3059 section symbols to be the name of the section they represent.
3060 Debugging symbols begin with "L$0\001", not just "L$".

3115 * som.c (som_prep_for_fixups): A relocation involving the section
3116 symbol for the *ABS* section is really a relocation involving
3118 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3119 undefined symbols. Correctly distinguish between debugger symbols
3120 and section symbols.

3123 for spaces and subspaces.
3125 * som.c (som_bfd_count_ar_symbols): Fix typo.

3159 cruft (like the #pragma alloca for AIX).
3160 In addition to that problem, the C alloca calls xmalloc, which
3161 means checking for being out of memory can't work right. The
3162 following changes remove all uses of alloca from BFD.

3209 (setup_sections): Bubble up an error from log2.
3211 * Changes to make HP C compiler happy in both traditional
3213 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

3216 unsigned char to avoid GNU-C extensions.
3217 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3218 or failure rather than aborting on failure.
3220 * som.h (bfd_som_set_section_attributes): Fix prototype to match

3265 creating them if necessary.
3267 * linker.c (_bfd_generic_link_output_symbols): Do not
3268 rebuild/clobber the output symbols if they already exist.

3499 * section.c (bfd_get_section_contents): Since this function reads
3500 unrelocated contents, the section's raw size is always the one to
3501 use for bounds checking.

3504 link_order size field against cooked size, not raw size, of input
3507 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
3509 (aligncode): When shrinking, the addend should be set to the
3510 current offset in the section plus the number of bytes of padding
3511 that will actually be retained.
3512 (b_out_relax_section): If a section contains no relocations, don't
3513 bother processing them.
3514 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3518 that reloc->addend falls between the current source offset and the
3519 raw size of the input section.

4047 (only testing for m68k and vax at the moment); do verify that the
4048 preprocessor didn't trash the arch name inside the string version.

4079 bfd_som_set_subsection_attributes): Change parameters from char
4080 to int. Following a prototype with an old-style function definition

4187 use get_value to get the symbol value and check for undefined
4189 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4190 undefined, look it up in the linker hash table.
4192 * aoutx.h (translate_symbol_table): The string index 0 has a

4217 The sparc (and possibly other?) NLM format requires a different
4218 way to write exports, so add a write_export field to the backend
4219 data (and set it to NULL for everything but the sparc).
