2919 dynamicly linked executables.)
2921 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2924 * som.c (som_begin_writing): Fix braino (one call to align

2962 subspace dictionaries be pointers (to save space when
2963 only reading objects).

2966 some references changed. Allocate a copyable data stucture if
2967 none exists. Store info into the copyable data structure.

2969 (som_is_space, som_is_subspace, som_is_container): New functions.
2970 Use these instead of directly accessing private data.

2972 Fill in some fields in the space/subspace headers from the
2974 (som_bfd_copy_private_section_data): Only copy the stuff
2975 that we really need to make objcopy and strip work. Allocate
2976 the copy_data structure for the output bfd before copying.

2979 info that must be preserved when running objcopy/strip.

2981 macro. Add some comments on how the various fields are used.
2982 (som_section_data_struct): Make is_space and is_subspace bitfields.

2991 It is not used when only reading SOM objects.
2992 (som_prep_headers): Allocate space for and attach a file header
2993 to the output bfd. For executables, use the saved system_id
2994 value rather than trying to guess the right value. Do not abort
2995 wwhen setting file_hdr->entry* for executables.
2996 (som_begin_writing): For executables, set the exec_entry and
2998 (som_copy_private_backend_section_data): Always return a value.
3000 * libhppa.h (PA_PAGESIZE): Define.

3003 (som_begin_writing): If writing an executable, initialize all
3004 fields in the exec header to zero. Update fields in the exec
3005 header as sizes of loadable subspaces are computed. Carefully
3006 preserve alignments when building executables. Actually write the
3007 exec after all the fields are filled in.
3009 * Better long-filename handling. Reads SOM ABI compliant extended
3010 names, but doesn't quite write compliant extended names yet.
3011 * som.c (som_slurp_extended_name_table): Delete function. The
3012 generic code will handle things correctly.
3013 (som_slurp_armap): Seek to the beginning of the next member.
3014 (normalize): New function.
3015 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3016 name table into account when computing the file offsets in the

3037 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3038 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3039 returns NULL, it is not an error. It's possible that some of
3040 these checks are not necessary (because the size can never be
3041 zero), but putting in the checks is the conservative thing to do
3042 in light of the fact that some of these malloc calls replaced
3043 unchecked alloca calls, in which a zero argument would work fine.
3045 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3047 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3048 duplicate definition.

3051 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3052 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3053 failure indication, it merely means there are no relocs.
3055 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3056 after NAME, since SunOS /bin/cc can't handle it.
3058 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3060 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3061 From sukes@glue.umd.edu (Tasuki Hirata).
3063 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3065 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3066 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3067 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3069 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3071 * som.c (som_prep_for_fixups): Detect section symbols based
3072 on either the lack of private data or the symbol flags. Do not
3073 munge section symbol names anymore -- they no longer confuse GDB.
3074 (som_begin_writing): Leave space for an exec header if writing
3076 (som_slurp_symbol_table): Recognize both forms of section symbol
3077 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3078 section symbols to be the name of the section they represent.
3079 Debugging symbols begin with "L$0\001", not just "L$".

3105 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3106 Default new vectors for copying private backend data to bfd_true.

3108 to bfd_generic_is_local_label.
3110 * som.c (som_bfd_copy_private_section_data): New function.
3111 (som_bfd_is_local_label): New function.

3116 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3118 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3120 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3123 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3124 Indent some of them to GNU standards.
3126 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3127 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

3129 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3130 Update copyright years.
3132 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3134 * som.c (som_prep_for_fixups): A relocation involving the section
3135 symbol for the *ABS* section is really a relocation involving
3137 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3138 undefined symbols. Correctly distinguish between debugger symbols
3139 and section symbols.
3141 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3142 for spaces and subspaces.
3144 * som.c (som_bfd_count_ar_symbols): Fix typo.
3146 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3147 HAS_RELOC based on the object's magic number.
3148 (make_unique_section): Delete function. BFD and its users are
3149 prepared to handle multiple sections with the same name.
3150 (setup_sections): Allocate space on the BFD's obstack to hold
3151 section names. Use bfd_make_setion_anyway rather than the
3152 obsolete make_unique_section.

3175 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3177 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3178 cruft (like the #pragma alloca for AIX).
3179 In addition to that problem, the C alloca calls xmalloc, which
3180 means checking for being out of memory can't work right. The
3181 following changes remove all uses of alloca from BFD.
3182 * hosts/solaris2.h: Remove alloca cruft.
3183 * som.c: Replace alloca with a fixed size auto array.

3198 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3199 Elf*_Off typedefs by their expansion, the typedefs have been
3200 removed from include/elf/internal.h.
3201 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3202 SHT_PROGBITS section.

3221 * som.[ch]: Do not include libhppa.h in som.c, instead include
3224 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3225 include it in elf32-hppa.h.
3227 * som.c (log2): Return -1 on error rather than aborting.
3228 (setup_sections): Bubble up an error from log2.
3230 * Changes to make HP C compiler happy in both traditional
3232 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

3235 unsigned char to avoid GNU-C extensions.
3236 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3237 or failure rather than aborting on failure.
3239 * som.h (bfd_som_set_section_attributes): Fix prototype to match

3282 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3283 argument. Use the output symbols when canonicalizing the relocs,
3284 creating them if necessary.
3286 * linker.c (_bfd_generic_link_output_symbols): Do not
3287 rebuild/clobber the output symbols if they already exist.

3306 #defines for lots of things. Merge two functions which build
3307 linker stubs into a single function (so they can easily share a
3308 ton of common code).

3356 COMPLEX relocation support (it's never used anyway).
3357 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

3531 (b_out_relax_section): If a section contains no relocations, don't
3532 bother processing them.
3533 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3537 that reloc->addend falls between the current source offset and the
3538 raw size of the input section.

4066 (only testing for m68k and vax at the moment); do verify that the
4067 preprocessor didn't trash the arch name inside the string version.

4098 bfd_som_set_subsection_attributes): Change parameters from char
4099 to int. Following a prototype with an old-style function definition

4206 use get_value to get the symbol value and check for undefined
4208 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4209 undefined, look it up in the linker hash table.
4211 * aoutx.h (translate_symbol_table): The string index 0 has a

4236 The sparc (and possibly other?) NLM format requires a different
4237 way to write exports, so add a write_export field to the backend
4238 data (and set it to NULL for everything but the sparc).
