568 symbol when no dynamic object was seen, initialize the contents of
569 the .got section. For a GOT reloc against a local symbol, only

4201 dynamicly linked executables.)
4203 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4206 * som.c (som_begin_writing): Fix braino (one call to align

4243 som_copyable_section_data_struct. Make the space and
4244 subspace dictionaries be pointers (to save space when
4245 only reading objects).
4247 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4248 some references changed. Allocate a copyable data stucture if
4249 none exists. Store info into the copyable data structure.

4251 (som_is_space, som_is_subspace, som_is_container): New functions.
4252 Use these instead of directly accessing private data.
4253 (som_prep_headers): Allocate space and subspace headers here.
4254 Fill in some fields in the space/subspace headers from the
4256 (som_bfd_copy_private_section_data): Only copy the stuff
4257 that we really need to make objcopy and strip work. Allocate
4258 the copy_data structure for the output bfd before copying.

4261 info that must be preserved when running objcopy/strip.

4263 macro. Add some comments on how the various fields are used.
4264 (som_section_data_struct): Make is_space and is_subspace bitfields.

4273 It is not used when only reading SOM objects.
4274 (som_prep_headers): Allocate space for and attach a file header
4275 to the output bfd. For executables, use the saved system_id
4276 value rather than trying to guess the right value. Do not abort
4277 wwhen setting file_hdr->entry* for executables.
4278 (som_begin_writing): For executables, set the exec_entry and
4280 (som_copy_private_backend_section_data): Always return a value.
4282 * libhppa.h (PA_PAGESIZE): Define.

4285 (som_begin_writing): If writing an executable, initialize all
4286 fields in the exec header to zero. Update fields in the exec
4287 header as sizes of loadable subspaces are computed. Carefully
4288 preserve alignments when building executables. Actually write the
4289 exec after all the fields are filled in.
4291 * Better long-filename handling. Reads SOM ABI compliant extended
4292 names, but doesn't quite write compliant extended names yet.
4293 * som.c (som_slurp_extended_name_table): Delete function. The
4294 generic code will handle things correctly.
4295 (som_slurp_armap): Seek to the beginning of the next member.
4296 (normalize): New function.
4297 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4298 name table into account when computing the file offsets in the
4299 SOM dictionary. Make sure to align to an even boundary.
4300 (som_write_armap): Initialize the checksum to zero.
4301 (ar_maxchars): Fix. Opps.

4319 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4320 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4321 returns NULL, it is not an error. It's possible that some of
4322 these checks are not necessary (because the size can never be
4323 zero), but putting in the checks is the conservative thing to do
4324 in light of the fact that some of these malloc calls replaced
4325 unchecked alloca calls, in which a zero argument would work fine.
4327 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4329 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4330 duplicate definition.

4333 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4334 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4335 failure indication, it merely means there are no relocs.
4337 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4338 after NAME, since SunOS /bin/cc can't handle it.
4340 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4342 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4343 From sukes@glue.umd.edu (Tasuki Hirata).
4345 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4347 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4348 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4349 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4351 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4353 * som.c (som_prep_for_fixups): Detect section symbols based
4354 on either the lack of private data or the symbol flags. Do not
4355 munge section symbol names anymore -- they no longer confuse GDB.
4356 (som_begin_writing): Leave space for an exec header if writing
4358 (som_slurp_symbol_table): Recognize both forms of section symbol
4359 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4360 section symbols to be the name of the section they represent.
4361 Debugging symbols begin with "L$0\001", not just "L$".

4387 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4388 Default new vectors for copying private backend data to bfd_true.

4390 to bfd_generic_is_local_label.
4392 * som.c (som_bfd_copy_private_section_data): New function.
4393 (som_bfd_is_local_label): New function.

4398 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4400 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4402 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4405 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4406 Indent some of them to GNU standards.
4408 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4409 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

4411 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4412 Update copyright years.
4414 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4416 * som.c (som_prep_for_fixups): A relocation involving the section
4417 symbol for the *ABS* section is really a relocation involving
4419 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4420 undefined symbols. Correctly distinguish between debugger symbols
4421 and section symbols.
4423 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4424 for spaces and subspaces.
4426 * som.c (som_bfd_count_ar_symbols): Fix typo.
4428 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4429 HAS_RELOC based on the object's magic number.
4430 (make_unique_section): Delete function. BFD and its users are
4431 prepared to handle multiple sections with the same name.
4432 (setup_sections): Allocate space on the BFD's obstack to hold
4433 section names. Use bfd_make_setion_anyway rather than the
4434 obsolete make_unique_section.
4435 (som_prep_headers): Choose the correct SOM magic number based
4437 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4457 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4459 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4460 cruft (like the #pragma alloca for AIX).
4461 In addition to that problem, the C alloca calls xmalloc, which
4462 means checking for being out of memory can't work right. The
4463 following changes remove all uses of alloca from BFD.
4464 * hosts/solaris2.h: Remove alloca cruft.
4465 * som.c: Replace alloca with a fixed size auto array.

4480 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4481 Elf*_Off typedefs by their expansion, the typedefs have been
4482 removed from include/elf/internal.h.
4483 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4484 SHT_PROGBITS section.

4497 TRAD_CORE_STACK_OFFSET.
4498 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4499 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.

4503 * som.[ch]: Do not include libhppa.h in som.c, instead include
4506 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4507 include it in elf32-hppa.h.
4509 * som.c (log2): Return -1 on error rather than aborting.
4510 (setup_sections): Bubble up an error from log2.
4512 * Changes to make HP C compiler happy in both traditional
4514 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4516 (bfd_som_set_section_attributes): Use unsigned int rather than
4517 unsigned char to avoid GNU-C extensions.
4518 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4519 or failure rather than aborting on failure.
4521 * som.h (bfd_som_set_section_attributes): Fix prototype to match

4564 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4565 argument. Use the output symbols when canonicalizing the relocs,
4566 creating them if necessary.
4568 * linker.c (_bfd_generic_link_output_symbols): Do not
4569 rebuild/clobber the output symbols if they already exist.

4588 #defines for lots of things. Merge two functions which build
4589 linker stubs into a single function (so they can easily share a
4590 ton of common code).

4638 COMPLEX relocation support (it's never used anyway).
4639 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

4813 (b_out_relax_section): If a section contains no relocations, don't
4814 bother processing them.
4815 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4819 that reloc->addend falls between the current source offset and the
4820 raw size of the input section.

4843 * Finish basic read-write support for SOM archive libraries. Bugs
4844 surely remain as this hasn't been tested all that much.
4845 * som.c (SOM_LST_HASH_SIZE, SOM_LST_MODULE_LIMIT): Define.
4846 (struct som_misc_symbol_info): New structure to hold info necessary

5348 (only testing for m68k and vax at the moment); do verify that the
5349 preprocessor didn't trash the arch name inside the string version.

5380 bfd_som_set_subsection_attributes): Change parameters from char
5381 to int. Following a prototype with an old-style function definition

5488 use get_value to get the symbol value and check for undefined
5490 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5491 undefined, look it up in the linker hash table.
5493 * aoutx.h (translate_symbol_table): The string index 0 has a

5518 The sparc (and possibly other?) NLM format requires a different
5519 way to write exports, so add a write_export field to the backend
5520 data (and set it to NULL for everything but the sparc).
