2924 dynamicly linked executables.)
2926 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2929 * som.c (som_begin_writing): Fix braino (one call to align

2967 subspace dictionaries be pointers (to save space when
2968 only reading objects).
2970 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2971 some references changed. Allocate a copyable data stucture if
2972 none exists. Store info into the copyable data structure.

2974 (som_is_space, som_is_subspace, som_is_container): New functions.
2975 Use these instead of directly accessing private data.

2977 Fill in some fields in the space/subspace headers from the
2979 (som_bfd_copy_private_section_data): Only copy the stuff
2980 that we really need to make objcopy and strip work. Allocate
2981 the copy_data structure for the output bfd before copying.

2984 info that must be preserved when running objcopy/strip.
2985 (struct somdata): Add new "exec_data" field and accessor
2986 macro. Add some comments on how the various fields are used.
2987 (som_section_data_struct): Make is_space and is_subspace bitfields.

2996 It is not used when only reading SOM objects.
2997 (som_prep_headers): Allocate space for and attach a file header
2998 to the output bfd. For executables, use the saved system_id
2999 value rather than trying to guess the right value. Do not abort
3000 wwhen setting file_hdr->entry* for executables.
3001 (som_begin_writing): For executables, set the exec_entry and
3003 (som_copy_private_backend_section_data): Always return a value.
3005 * libhppa.h (PA_PAGESIZE): Define.

3008 (som_begin_writing): If writing an executable, initialize all
3009 fields in the exec header to zero. Update fields in the exec
3010 header as sizes of loadable subspaces are computed. Carefully
3011 preserve alignments when building executables. Actually write the
3012 exec after all the fields are filled in.
3014 * Better long-filename handling. Reads SOM ABI compliant extended
3015 names, but doesn't quite write compliant extended names yet.
3016 * som.c (som_slurp_extended_name_table): Delete function. The
3017 generic code will handle things correctly.
3018 (som_slurp_armap): Seek to the beginning of the next member.
3019 (normalize): New function.
3020 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
3021 name table into account when computing the file offsets in the

3035 * bfd-in2.h: Regenerated.
3037 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
3038 this was also named trad_unix_bfd_copy_private_bfd_data.
3040 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3042 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
3043 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
3044 returns NULL, it is not an error. It's possible that some of
3045 these checks are not necessary (because the size can never be
3046 zero), but putting in the checks is the conservative thing to do
3047 in light of the fact that some of these malloc calls replaced
3048 unchecked alloca calls, in which a zero argument would work fine.
3050 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3052 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
3053 duplicate definition.

3056 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
3057 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
3058 failure indication, it merely means there are no relocs.
3060 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
3061 after NAME, since SunOS /bin/cc can't handle it.
3063 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
3065 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
3066 From sukes@glue.umd.edu (Tasuki Hirata).
3068 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3070 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
3071 all that convoluted stuff with NAME, CAT3, etc. The convoluted
3072 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
3074 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3076 * som.c (som_prep_for_fixups): Detect section symbols based
3077 on either the lack of private data or the symbol flags. Do not
3078 munge section symbol names anymore -- they no longer confuse GDB.
3079 (som_begin_writing): Leave space for an exec header if writing
3081 (som_slurp_symbol_table): Recognize both forms of section symbol
3082 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
3083 section symbols to be the name of the section they represent.
3084 Debugging symbols begin with "L$0\001", not just "L$".

3110 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
3111 Default new vectors for copying private backend data to bfd_true.

3113 to bfd_generic_is_local_label.
3115 * som.c (som_bfd_copy_private_section_data): New function.
3116 (som_bfd_is_local_label): New function.

3121 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3123 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
3125 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
3128 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
3129 Indent some of them to GNU standards.
3131 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
3132 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

3134 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
3135 Update copyright years.
3137 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3139 * som.c (som_prep_for_fixups): A relocation involving the section
3140 symbol for the *ABS* section is really a relocation involving
3142 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
3143 undefined symbols. Correctly distinguish between debugger symbols
3144 and section symbols.
3146 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
3147 for spaces and subspaces.
3149 * som.c (som_bfd_count_ar_symbols): Fix typo.
3151 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
3152 HAS_RELOC based on the object's magic number.
3153 (make_unique_section): Delete function. BFD and its users are
3154 prepared to handle multiple sections with the same name.
3155 (setup_sections): Allocate space on the BFD's obstack to hold
3156 section names. Use bfd_make_setion_anyway rather than the
3157 obsolete make_unique_section.
3158 (som_prep_headers): Choose the correct SOM magic number based
3160 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

3180 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3182 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3183 cruft (like the #pragma alloca for AIX).
3184 In addition to that problem, the C alloca calls xmalloc, which
3185 means checking for being out of memory can't work right. The
3186 following changes remove all uses of alloca from BFD.
3187 * hosts/solaris2.h: Remove alloca cruft.
3188 * som.c: Replace alloca with a fixed size auto array.

3201 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3203 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3204 Elf*_Off typedefs by their expansion, the typedefs have been
3205 removed from include/elf/internal.h.
3206 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3207 SHT_PROGBITS section.

3226 * som.[ch]: Do not include libhppa.h in som.c, instead include
3229 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3230 include it in elf32-hppa.h.
3232 * som.c (log2): Return -1 on error rather than aborting.
3233 (setup_sections): Bubble up an error from log2.
3235 * Changes to make HP C compiler happy in both traditional
3237 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

3240 unsigned char to avoid GNU-C extensions.
3241 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3242 or failure rather than aborting on failure.
3244 * som.h (bfd_som_set_section_attributes): Fix prototype to match

3287 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3288 argument. Use the output symbols when canonicalizing the relocs,
3289 creating them if necessary.
3291 * linker.c (_bfd_generic_link_output_symbols): Do not
3292 rebuild/clobber the output symbols if they already exist.

3310 Add FIXMEs for unresolved problems. Use enums rather than
3311 #defines for lots of things. Merge two functions which build
3312 linker stubs into a single function (so they can easily share a
3313 ton of common code).

3317 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to

3361 COMPLEX relocation support (it's never used anyway).
3362 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

3409 to make sure CPU_PA_RISC1_0 is always defined.
3411 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
3413 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

3537 bother processing them.
3538 (b_out_get_relocated_section_contents): Set reloc_done. Assert

3952 "unsigned", some compilers don't like it after "unsigned".
3953 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

4025 _bfd_generic_link_write_global_symbol): Don't require that all
4026 references to a common symbol be themselves common symbols.

4071 (only testing for m68k and vax at the moment); do verify that the
4072 preprocessor didn't trash the arch name inside the string version.

4103 bfd_som_set_subsection_attributes): Change parameters from char
4104 to int. Following a prototype with an old-style function definition

4211 use get_value to get the symbol value and check for undefined
4213 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
4214 undefined, look it up in the linker hash table.
4216 * aoutx.h (translate_symbol_table): The string index 0 has a

4241 The sparc (and possibly other?) NLM format requires a different
4242 way to write exports, so add a write_export field to the backend
4243 data (and set it to NULL for everything but the sparc).
