2829 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2830 from call to _bfd_generic_link_add_one_symbol.
2831 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2832 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR

2879 For executables, iterate through the sections to find out
2880 which contains the symbol's address rather than using the
2881 symbol_info field. (symbol_info has a different meaning for
2882 dynamicly linked executables.)
2884 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2887 * som.c (som_begin_writing): Fix braino (one call to align
2888 space/subspace data was done unconditionally rather than
2889 just for executables.)
2891 * som.c (som_begin_writing): Align text in all executables to
2892 make HPUX kernel happy. Fixes strip/objcopy for shared
2895 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2897 * som.c (som_begin_writing): Account for alignment needs of
2898 subspaces too when writing executables. Never request a negative
2899 bss size. Fixes some problems with demand paged executables,
2900 still having problems with pure executables and shared executables.
2902 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2904 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2905 bfd_zalloc for rawptr, because later on we may call free, not
2908 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.

2919 * som.h (som_copyable_section_data_struct): New structure
2920 containing all the private section information which needs
2921 to be copied from input section to output section during
2923 (som_section_data_struct): Remove several fields now in
2924 som_copyable_section_data_struct. Make the space and
2925 subspace dictionaries be pointers (to save space when
2926 only reading objects).
2928 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2929 some references changed. Allocate a copyable data stucture if
2930 none exists. Store info into the copyable data structure.
2931 (bfd_som_set_subsection_attributes): Likewise.
2932 (som_is_space, som_is_subspace, som_is_container): New functions.
2933 Use these instead of directly accessing private data.
2934 (som_prep_headers): Allocate space and subspace headers here.
2935 Fill in some fields in the space/subspace headers from the
2937 (som_bfd_copy_private_section_data): Only copy the stuff
2938 that we really need to make objcopy and strip work. Allocate
2939 the copy_data structure for the output bfd before copying.
2941 * som.h (struct som_exec_data): New structure to hold exec
2942 info that must be preserved when running objcopy/strip.
2943 (struct somdata): Add new "exec_data" field and accessor
2944 macro. Add some comments on how the various fields are used.
2945 (som_section_data_struct): Make is_space and is_subspace bitfields.
2946 Delete unused subspace_index. All references now use the
2947 target_index field within the section structure itself.
2949 * som.c (make_unique_section): Delete unused declaration.
2950 (som_bfd_copy_private_bfd_data): New function.
2951 (som_object_setup): Allocate space for and save exec information
2952 that needs to be copied during objcopy/strip.
2953 (som_mkobject): Do not allocate space for a file header here.
2954 It is not used when only reading SOM objects.
2955 (som_prep_headers): Allocate space for and attach a file header
2956 to the output bfd. For executables, use the saved system_id
2957 value rather than trying to guess the right value. Do not abort
2958 wwhen setting file_hdr->entry* for executables.
2959 (som_begin_writing): For executables, set the exec_entry and
2961 (som_copy_private_backend_section_data): Always return a value.
2963 * libhppa.h (PA_PAGESIZE): Define.
2965 * som.c (SOM_ALIGN): Define.
2966 (som_begin_writing): If writing an executable, initialize all
2967 fields in the exec header to zero. Update fields in the exec
2968 header as sizes of loadable subspaces are computed. Carefully
2969 preserve alignments when building executables. Actually write the
2970 exec after all the fields are filled in.
2972 * Better long-filename handling. Reads SOM ABI compliant extended
2973 names, but doesn't quite write compliant extended names yet.
2974 * som.c (som_slurp_extended_name_table): Delete function. The
2975 generic code will handle things correctly.
2976 (som_slurp_armap): Seek to the beginning of the next member.
2977 (normalize): New function.
2978 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2979 name table into account when computing the file offsets in the
2980 SOM dictionary. Make sure to align to an even boundary.
2981 (som_write_armap): Initialize the checksum to zero.
2982 (ar_maxchars): Fix. Opps.

2986 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2987 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

2992 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2993 * bfd-in2.h: Regenerated.
2995 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2996 this was also named trad_unix_bfd_copy_private_bfd_data.
2998 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3000 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3001 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3002 returns NULL, it is not an error. It's possible that some of
3003 these checks are not necessary (because the size can never be
3004 zero), but putting in the checks is the conservative thing to do
3005 in light of the fact that some of these malloc calls replaced
3006 unchecked alloca calls, in which a zero argument would work fine.
3008 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3010 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3011 duplicate definition.
3012 (osf_core_bfd_is_local_label): Define.
3014 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3015 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3016 failure indication, it merely means there are no relocs.
3018 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3019 after NAME, since SunOS /bin/cc can't handle it.
3021 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3023 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3024 From sukes@glue.umd.edu (Tasuki Hirata).

3028 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3029 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3030 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3032 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3034 * som.c (som_prep_for_fixups): Detect section symbols based

3039 (som_slurp_symbol_table): Recognize both forms of section symbol
3040 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3041 section symbols to be the name of the section they represent.

3097 * som.c (som_prep_for_fixups): A relocation involving the section
3098 symbol for the *ABS* section is really a relocation involving
3100 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3101 undefined symbols. Correctly distinguish between debugger symbols
3102 and section symbols.
3104 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3105 for spaces and subspaces.
3107 * som.c (som_bfd_count_ar_symbols): Fix typo.

3112 prepared to handle multiple sections with the same name.
3113 (setup_sections): Allocate space on the BFD's obstack to hold
3114 section names. Use bfd_make_setion_anyway rather than the

3141 cruft (like the #pragma alloca for AIX).
3142 In addition to that problem, the C alloca calls xmalloc, which
3143 means checking for being out of memory can't work right. The
3144 following changes remove all uses of alloca from BFD.

3187 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3188 include it in elf32-hppa.h.
3190 * som.c (log2): Return -1 on error rather than aborting.
3191 (setup_sections): Bubble up an error from log2.
3193 * Changes to make HP C compiler happy in both traditional
3195 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

3198 unsigned char to avoid GNU-C extensions.
3199 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3200 or failure rather than aborting on failure.
3202 * som.h (bfd_som_set_section_attributes): Fix prototype to match

3479 Tue Feb 15 19:39:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3481 * section.c (bfd_get_section_contents): Since this function reads
3482 unrelocated contents, the section's raw size is always the one to
3483 use for bounds checking.

3486 link_order size field against cooked size, not raw size, of input
3489 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just

3492 current offset in the section plus the number of bytes of padding
3493 that will actually be retained.
3494 (b_out_relax_section): If a section contains no relocations, don't
3495 bother processing them.
3496 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3499 (b_out_get_relocated_section_contents, case ALIGNDONE): Assert
3500 that reloc->addend falls between the current source offset and the
3501 raw size of the input section.

3504 bout. Default with no version number is still bout. Support
3505 explicit i960-coff target too.

3983 _bfd_generic_link_write_global_symbol): Don't require that all
3984 references to a common symbol be themselves common symbols.

4029 (only testing for m68k and vax at the moment); do verify that the
4030 preprocessor didn't trash the arch name inside the string version.

4061 bfd_som_set_subsection_attributes): Change parameters from char
4062 to int. Following a prototype with an old-style function definition

4169 use get_value to get the symbol value and check for undefined
4171 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4172 undefined, look it up in the linker hash table.
4174 * aoutx.h (translate_symbol_table): The string index 0 has a

4199 The sparc (and possibly other?) NLM format requires a different
4200 way to write exports, so add a write_export field to the backend
4201 data (and set it to NULL for everything but the sparc).
