5234 (som_is_space, som_is_subspace, som_is_container): New functions.
5235 Use these instead of directly accessing private data.
5236 (som_prep_headers): Allocate space and subspace headers here.
5237 Fill in some fields in the space/subspace headers from the
5239 (som_bfd_copy_private_section_data): Only copy the stuff
5240 that we really need to make objcopy and strip work. Allocate
5241 the copy_data structure for the output bfd before copying.
5243 * som.h (struct som_exec_data): New structure to hold exec
5244 info that must be preserved when running objcopy/strip.
5245 (struct somdata): Add new "exec_data" field and accessor
5246 macro. Add some comments on how the various fields are used.
5247 (som_section_data_struct): Make is_space and is_subspace bitfields.
5248 Delete unused subspace_index. All references now use the
5249 target_index field within the section structure itself.
5251 * som.c (make_unique_section): Delete unused declaration.
5252 (som_bfd_copy_private_bfd_data): New function.
5253 (som_object_setup): Allocate space for and save exec information
5254 that needs to be copied during objcopy/strip.
5255 (som_mkobject): Do not allocate space for a file header here.
5256 It is not used when only reading SOM objects.
5257 (som_prep_headers): Allocate space for and attach a file header
5258 to the output bfd. For executables, use the saved system_id
5259 value rather than trying to guess the right value. Do not abort
5260 wwhen setting file_hdr->entry* for executables.
5261 (som_begin_writing): For executables, set the exec_entry and
5263 (som_copy_private_backend_section_data): Always return a value.
5265 * libhppa.h (PA_PAGESIZE): Define.
5267 * som.c (SOM_ALIGN): Define.
5268 (som_begin_writing): If writing an executable, initialize all
5269 fields in the exec header to zero. Update fields in the exec
5270 header as sizes of loadable subspaces are computed. Carefully
5271 preserve alignments when building executables. Actually write the
5272 exec after all the fields are filled in.
5274 * Better long-filename handling. Reads SOM ABI compliant extended
5275 names, but doesn't quite write compliant extended names yet.
5276 * som.c (som_slurp_extended_name_table): Delete function. The
5277 generic code will handle things correctly.
5278 (som_slurp_armap): Seek to the beginning of the next member.
5279 (normalize): New function.
5280 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5281 name table into account when computing the file offsets in the
5282 SOM dictionary. Make sure to align to an even boundary.
5283 (som_write_armap): Initialize the checksum to zero.
5284 (ar_maxchars): Fix. Opps.
5286 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5288 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5289 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5291 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5293 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5294 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5295 * bfd-in2.h: Regenerated.
5297 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5298 this was also named trad_unix_bfd_copy_private_bfd_data.
5300 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5302 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5303 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5304 returns NULL, it is not an error. It's possible that some of
5305 these checks are not necessary (because the size can never be
5306 zero), but putting in the checks is the conservative thing to do
5307 in light of the fact that some of these malloc calls replaced
5308 unchecked alloca calls, in which a zero argument would work fine.
5310 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5312 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5313 duplicate definition.

5316 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5317 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5318 failure indication, it merely means there are no relocs.
5320 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5321 after NAME, since SunOS /bin/cc can't handle it.
5323 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5325 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5326 From sukes@glue.umd.edu (Tasuki Hirata).
5328 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5330 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5331 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5332 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5334 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5336 * som.c (som_prep_for_fixups): Detect section symbols based
5337 on either the lack of private data or the symbol flags. Do not
5338 munge section symbol names anymore -- they no longer confuse GDB.
5339 (som_begin_writing): Leave space for an exec header if writing
5341 (som_slurp_symbol_table): Recognize both forms of section symbol
5342 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5343 section symbols to be the name of the section they represent.
5344 Debugging symbols begin with "L$0\001", not just "L$".
5346 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5348 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5350 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5351 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5352 and bfd_is_local_label.
5354 * targets.c: Add new entries to the bfd_target structure.
5356 * bfd.c (bfd_copy_private_bfd_data): New definition.

5367 the target vector which all point to bfd_false.
5369 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5370 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5371 Default new vectors for copying private backend data to bfd_true.
5372 Default new vector for determining if a symbol is a local label
5373 to bfd_generic_is_local_label.
5375 * som.c (som_bfd_copy_private_section_data): New function.
5376 (som_bfd_is_local_label): New function.
5377 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5379 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5381 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5383 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5385 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5388 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5389 Indent some of them to GNU standards.
5391 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5392 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5393 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5394 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5395 Update copyright years.
5397 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5399 * som.c (som_prep_for_fixups): A relocation involving the section
5400 symbol for the *ABS* section is really a relocation involving
5402 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5403 undefined symbols. Correctly distinguish between debugger symbols
5404 and section symbols.
5406 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5407 for spaces and subspaces.
5409 * som.c (som_bfd_count_ar_symbols): Fix typo.
5411 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5412 HAS_RELOC based on the object's magic number.
5413 (make_unique_section): Delete function. BFD and its users are
5414 prepared to handle multiple sections with the same name.
5415 (setup_sections): Allocate space on the BFD's obstack to hold
5416 section names. Use bfd_make_setion_anyway rather than the
5417 obsolete make_unique_section.
5418 (som_prep_headers): Choose the correct SOM magic number based
5420 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

5440 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5442 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5443 cruft (like the #pragma alloca for AIX).
5444 In addition to that problem, the C alloca calls xmalloc, which
5445 means checking for being out of memory can't work right. The
5446 following changes remove all uses of alloca from BFD.
5447 * hosts/solaris2.h: Remove alloca cruft.
5448 * som.c: Replace alloca with a fixed size auto array.

5453 * linker.c: Replace alloca with obstack_alloc.
5454 * libbfd.h: Rebuilt.
5456 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5458 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5461 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5463 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5464 Elf*_Off typedefs by their expansion, the typedefs have been
5465 removed from include/elf/internal.h.
5466 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5467 SHT_PROGBITS section.
5469 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5471 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5480 TRAD_CORE_STACK_OFFSET.
5481 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5482 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5484 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5486 * som.[ch]: Do not include libhppa.h in som.c, instead include
5489 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5490 include it in elf32-hppa.h.
5492 * som.c (log2): Return -1 on error rather than aborting.
5493 (setup_sections): Bubble up an error from log2.
5495 * Changes to make HP C compiler happy in both traditional
5497 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5499 (bfd_som_set_section_attributes): Use unsigned int rather than
5500 unsigned char to avoid GNU-C extensions.
5501 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5502 or failure rather than aborting on failure.
5504 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5506 (bfd_som_attach_aux_hdr): Add prototype.
5507 (hppa_som-gen_reloc_type): Likewise.

5541 unused symbols argument.
5543 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5545 Set reloc->sym_ptr_ptr appropriately.
5546 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5547 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5548 argument. Use the output symbols when canonicalizing the relocs,
5549 creating them if necessary.
5551 * linker.c (_bfd_generic_link_output_symbols): Do not
5552 rebuild/clobber the output symbols if they already exist.
5554 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5556 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

5569 error code propogation working. Work on spacing and indention.
5570 Add FIXMEs for unresolved problems. Use enums rather than
5571 #defines for lots of things. Merge two functions which build
5572 linker stubs into a single function (so they can easily share a
5573 ton of common code).
5575 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5577 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5578 avoid depending upon right shifts of signed numbers, and to
5579 correct handling of src_mask with lower bits zero.

5609 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5610 (elf_hppa_tc_make_sections): Likewise.
5611 (elf_hppa_final_processing): Add extern decl.
5613 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5614 comments. PARAMize some static functions. Delete unused functions.
5615 Delete unused/unnecessary arguments to many functions. Group
5616 static vars together. Collapse common case statements together
5617 in many places. Use default case when possible instead of listing
5618 each case separately. Abort for bad errors until we get error
5619 code propogation working. Work on spacing and indention problems.
5620 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5621 COMPLEX relocation support (it's never used anyway).
5622 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5623 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5624 (elf_hppa_tc_make_sections): Likewise.

5665 * elfcode.h (alloca): Delete declaration.
5667 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5668 number rather than HP9000S800_ID. Note som.c is careful
5669 to make sure CPU_PA_RISC1_0 is always defined.
5671 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5673 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

6331 (only testing for m68k and vax at the moment); do verify that the
6332 preprocessor didn't trash the arch name inside the string version.

6363 bfd_som_set_subsection_attributes): Change parameters from char
6364 to int. Following a prototype with an old-style function definition

6467 the symbol value and check for undefined symbols.
6468 (get_value): If the symbol is undefined, look it up in the linker
6470 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
6471 use get_value to get the symbol value and check for undefined
6473 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6474 undefined, look it up in the linker hash table.
6476 * aoutx.h (translate_symbol_table): The string index 0 has a

6501 The sparc (and possibly other?) NLM format requires a different
6502 way to write exports, so add a write_export field to the backend
6503 data (and set it to NULL for everything but the sparc).

6553 read_dynamic_relocs fields.
6554 * aout-target.h (MY(backend_data)): Initialize
