4321 som_copyable_section_data_struct. Make the space and
4322 subspace dictionaries be pointers (to save space when
4323 only reading objects).
4325 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4326 some references changed. Allocate a copyable data stucture if
4327 none exists. Store info into the copyable data structure.
4328 (bfd_som_set_subsection_attributes): Likewise.
4329 (som_is_space, som_is_subspace, som_is_container): New functions.
4330 Use these instead of directly accessing private data.
4331 (som_prep_headers): Allocate space and subspace headers here.
4332 Fill in some fields in the space/subspace headers from the
4334 (som_bfd_copy_private_section_data): Only copy the stuff
4335 that we really need to make objcopy and strip work. Allocate
4336 the copy_data structure for the output bfd before copying.
4338 * som.h (struct som_exec_data): New structure to hold exec
4339 info that must be preserved when running objcopy/strip.
4340 (struct somdata): Add new "exec_data" field and accessor
4341 macro. Add some comments on how the various fields are used.
4342 (som_section_data_struct): Make is_space and is_subspace bitfields.
4343 Delete unused subspace_index. All references now use the
4344 target_index field within the section structure itself.
4346 * som.c (make_unique_section): Delete unused declaration.
4347 (som_bfd_copy_private_bfd_data): New function.
4348 (som_object_setup): Allocate space for and save exec information
4349 that needs to be copied during objcopy/strip.
4350 (som_mkobject): Do not allocate space for a file header here.
4351 It is not used when only reading SOM objects.
4352 (som_prep_headers): Allocate space for and attach a file header
4353 to the output bfd. For executables, use the saved system_id
4354 value rather than trying to guess the right value. Do not abort
4355 wwhen setting file_hdr->entry* for executables.
4356 (som_begin_writing): For executables, set the exec_entry and
4358 (som_copy_private_backend_section_data): Always return a value.
4360 * libhppa.h (PA_PAGESIZE): Define.
4362 * som.c (SOM_ALIGN): Define.
4363 (som_begin_writing): If writing an executable, initialize all
4364 fields in the exec header to zero. Update fields in the exec
4365 header as sizes of loadable subspaces are computed. Carefully
4366 preserve alignments when building executables. Actually write the
4367 exec after all the fields are filled in.
4369 * Better long-filename handling. Reads SOM ABI compliant extended
4370 names, but doesn't quite write compliant extended names yet.
4371 * som.c (som_slurp_extended_name_table): Delete function. The
4372 generic code will handle things correctly.
4373 (som_slurp_armap): Seek to the beginning of the next member.
4374 (normalize): New function.
4375 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4376 name table into account when computing the file offsets in the
4377 SOM dictionary. Make sure to align to an even boundary.
4378 (som_write_armap): Initialize the checksum to zero.
4379 (ar_maxchars): Fix. Opps.
4381 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4383 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4384 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4386 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4388 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4389 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4390 * bfd-in2.h: Regenerated.
4392 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4393 this was also named trad_unix_bfd_copy_private_bfd_data.
4395 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4397 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4398 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4399 returns NULL, it is not an error. It's possible that some of
4400 these checks are not necessary (because the size can never be
4401 zero), but putting in the checks is the conservative thing to do
4402 in light of the fact that some of these malloc calls replaced
4403 unchecked alloca calls, in which a zero argument would work fine.
4405 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4407 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4408 duplicate definition.
4409 (osf_core_bfd_is_local_label): Define.
4411 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4412 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4413 failure indication, it merely means there are no relocs.
4415 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4416 after NAME, since SunOS /bin/cc can't handle it.
4418 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4420 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4421 From sukes@glue.umd.edu (Tasuki Hirata).
4423 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4425 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4426 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4427 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4429 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4431 * som.c (som_prep_for_fixups): Detect section symbols based
4432 on either the lack of private data or the symbol flags. Do not
4433 munge section symbol names anymore -- they no longer confuse GDB.
4434 (som_begin_writing): Leave space for an exec header if writing
4436 (som_slurp_symbol_table): Recognize both forms of section symbol
4437 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4438 section symbols to be the name of the section they represent.
4439 Debugging symbols begin with "L$0\001", not just "L$".
4441 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4443 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4445 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4446 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4447 and bfd_is_local_label.
4449 * targets.c: Add new entries to the bfd_target structure.
4451 * bfd.c (bfd_copy_private_bfd_data): New definition.

4457 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4459 * libbfd.c (bfd_generic_is_local_label): New function.
4461 * *-core.c: Provide default definitions for new functions in
4462 the target vector which all point to bfd_false.
4464 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4465 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4466 Default new vectors for copying private backend data to bfd_true.
4467 Default new vector for determining if a symbol is a local label
4468 to bfd_generic_is_local_label.
4470 * som.c (som_bfd_copy_private_section_data): New function.
4471 (som_bfd_is_local_label): New function.
4472 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4474 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4476 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4478 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4480 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4483 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4484 Indent some of them to GNU standards.
4486 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4487 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4488 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4489 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4490 Update copyright years.
4492 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4494 * som.c (som_prep_for_fixups): A relocation involving the section
4495 symbol for the *ABS* section is really a relocation involving
4497 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4498 undefined symbols. Correctly distinguish between debugger symbols
4499 and section symbols.
4501 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4502 for spaces and subspaces.
4504 * som.c (som_bfd_count_ar_symbols): Fix typo.
4506 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4507 HAS_RELOC based on the object's magic number.
4508 (make_unique_section): Delete function. BFD and its users are
4509 prepared to handle multiple sections with the same name.
4510 (setup_sections): Allocate space on the BFD's obstack to hold
4511 section names. Use bfd_make_setion_anyway rather than the
4512 obsolete make_unique_section.
4513 (som_prep_headers): Choose the correct SOM magic number based
4515 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4529 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4530 is always located at the start of the data section to allow
4531 recovery of the dynamic info from a stripped executable.
4532 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4535 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4537 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4538 cruft (like the #pragma alloca for AIX).
4539 In addition to that problem, the C alloca calls xmalloc, which
4540 means checking for being out of memory can't work right. The
4541 following changes remove all uses of alloca from BFD.
4542 * hosts/solaris2.h: Remove alloca cruft.
4543 * som.c: Replace alloca with a fixed size auto array.
4544 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

4546 sunos.c: Replace alloca with malloc and appropriate error checking and
4548 * linker.c: Replace alloca with obstack_alloc.
4549 * libbfd.h: Rebuilt.
4551 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4553 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4556 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4558 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4559 Elf*_Off typedefs by their expansion, the typedefs have been
4560 removed from include/elf/internal.h.
4561 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4562 SHT_PROGBITS section.
4564 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4566 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4572 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4573 return from bfd_seek indicates an error.
4574 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4575 TRAD_CORE_STACK_OFFSET.
4576 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4577 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4579 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4581 * som.[ch]: Do not include libhppa.h in som.c, instead include
4584 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4585 include it in elf32-hppa.h.
4587 * som.c (log2): Return -1 on error rather than aborting.
4588 (setup_sections): Bubble up an error from log2.
4590 * Changes to make HP C compiler happy in both traditional
4592 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4594 (bfd_som_set_section_attributes): Use unsigned int rather than
4595 unsigned char to avoid GNU-C extensions.
4596 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4597 or failure rather than aborting on failure.
4599 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4601 (bfd_som_attach_aux_hdr): Add prototype.
4602 (hppa_som-gen_reloc_type): Likewise.
4604 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4605 (hppa_look_for_stubs_in_section): Do not return false on failure
4606 until rest of code is ready to handle it. Abort for now.

4631 action in case where caller specified no argument relocation.
4632 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4633 right in the original relocation and the stub's relocation.
4635 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4636 unused symbols argument.
4638 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

4640 Set reloc->sym_ptr_ptr appropriately.
4641 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4642 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4643 argument. Use the output symbols when canonicalizing the relocs,
4644 creating them if necessary.
4646 * linker.c (_bfd_generic_link_output_symbols): Do not
4647 rebuild/clobber the output symbols if they already exist.
4649 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4651 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

4661 PARAMize and staticize rest of functions. Delete unused
4662 functions. Delete unused/unnecessary arguments to some functions.
4663 Group static vars together. Abort for bad errors until we have
4664 error code propogation working. Work on spacing and indention.
4665 Add FIXMEs for unresolved problems. Use enums rather than
4666 #defines for lots of things. Merge two functions which build
4667 linker stubs into a single function (so they can easily share a
4668 ton of common code).
4670 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4672 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4673 avoid depending upon right shifts of signed numbers, and to
4674 correct handling of src_mask with lower bits zero.

4704 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
4705 (elf_hppa_tc_make_sections): Likewise.
4706 (elf_hppa_final_processing): Add extern decl.
4708 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4709 comments. PARAMize some static functions. Delete unused functions.
4710 Delete unused/unnecessary arguments to many functions. Group
4711 static vars together. Collapse common case statements together
4712 in many places. Use default case when possible instead of listing
4713 each case separately. Abort for bad errors until we get error
4714 code propogation working. Work on spacing and indention problems.
4715 Add FIXMEs for some unresolved problems. Delete hopelessly broken
4716 COMPLEX relocation support (it's never used anyway).
4717 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4718 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4719 (elf_hppa_tc_make_sections): Likewise.

4732 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
4734 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

4760 * elfcode.h (alloca): Delete declaration.
4762 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
4763 number rather than HP9000S800_ID. Note som.c is careful
4764 to make sure CPU_PA_RISC1_0 is always defined.
4766 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
4768 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

5380 _bfd_generic_link_write_global_symbol): Don't require that all

5458 bfd_som_set_subsection_attributes): Change parameters from char
5459 to int. Following a prototype with an old-style function definition

5566 use get_value to get the symbol value and check for undefined
5568 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5569 undefined, look it up in the linker hash table.
5571 * aoutx.h (translate_symbol_table): The string index 0 has a

5596 The sparc (and possibly other?) NLM format requires a different
5597 way to write exports, so add a write_export field to the backend
5598 data (and set it to NULL for everything but the sparc).

5648 read_dynamic_relocs fields.
5649 * aout-target.h (MY(backend_data)): Initialize
