4318 * targets.c: Add cisco_core_vec.
4319 * bfd-in2.h: Rebuilt.
4321 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4323 * som.h (som_copyable_section_data_struct): New structure
4324 containing all the private section information which needs
4325 to be copied from input section to output section during
4327 (som_section_data_struct): Remove several fields now in
4328 som_copyable_section_data_struct. Make the space and
4329 subspace dictionaries be pointers (to save space when
4330 only reading objects).
4332 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4333 some references changed. Allocate a copyable data stucture if
4334 none exists. Store info into the copyable data structure.
4335 (bfd_som_set_subsection_attributes): Likewise.
4336 (som_is_space, som_is_subspace, som_is_container): New functions.
4337 Use these instead of directly accessing private data.
4338 (som_prep_headers): Allocate space and subspace headers here.
4339 Fill in some fields in the space/subspace headers from the
4341 (som_bfd_copy_private_section_data): Only copy the stuff
4342 that we really need to make objcopy and strip work. Allocate
4343 the copy_data structure for the output bfd before copying.
4345 * som.h (struct som_exec_data): New structure to hold exec
4346 info that must be preserved when running objcopy/strip.
4347 (struct somdata): Add new "exec_data" field and accessor
4348 macro. Add some comments on how the various fields are used.
4349 (som_section_data_struct): Make is_space and is_subspace bitfields.
4350 Delete unused subspace_index. All references now use the
4351 target_index field within the section structure itself.
4353 * som.c (make_unique_section): Delete unused declaration.
4354 (som_bfd_copy_private_bfd_data): New function.
4355 (som_object_setup): Allocate space for and save exec information
4356 that needs to be copied during objcopy/strip.
4357 (som_mkobject): Do not allocate space for a file header here.
4358 It is not used when only reading SOM objects.
4359 (som_prep_headers): Allocate space for and attach a file header
4360 to the output bfd. For executables, use the saved system_id
4361 value rather than trying to guess the right value. Do not abort
4362 wwhen setting file_hdr->entry* for executables.
4363 (som_begin_writing): For executables, set the exec_entry and
4365 (som_copy_private_backend_section_data): Always return a value.
4367 * libhppa.h (PA_PAGESIZE): Define.
4369 * som.c (SOM_ALIGN): Define.
4370 (som_begin_writing): If writing an executable, initialize all
4371 fields in the exec header to zero. Update fields in the exec
4372 header as sizes of loadable subspaces are computed. Carefully
4373 preserve alignments when building executables. Actually write the
4374 exec after all the fields are filled in.
4376 * Better long-filename handling. Reads SOM ABI compliant extended
4377 names, but doesn't quite write compliant extended names yet.
4378 * som.c (som_slurp_extended_name_table): Delete function. The
4379 generic code will handle things correctly.
4380 (som_slurp_armap): Seek to the beginning of the next member.
4381 (normalize): New function.
4382 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4383 name table into account when computing the file offsets in the
4384 SOM dictionary. Make sure to align to an even boundary.
4385 (som_write_armap): Initialize the checksum to zero.
4386 (ar_maxchars): Fix. Opps.
4388 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4390 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4391 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4393 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4395 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4396 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4397 * bfd-in2.h: Regenerated.
4399 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4400 this was also named trad_unix_bfd_copy_private_bfd_data.
4402 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4404 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4405 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4406 returns NULL, it is not an error. It's possible that some of
4407 these checks are not necessary (because the size can never be
4408 zero), but putting in the checks is the conservative thing to do
4409 in light of the fact that some of these malloc calls replaced
4410 unchecked alloca calls, in which a zero argument would work fine.
4412 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4414 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4415 duplicate definition.
4416 (osf_core_bfd_is_local_label): Define.
4418 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4419 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4420 failure indication, it merely means there are no relocs.
4422 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4423 after NAME, since SunOS /bin/cc can't handle it.
4425 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4427 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4428 From sukes@glue.umd.edu (Tasuki Hirata).
4430 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4432 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4433 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4434 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4436 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4438 * som.c (som_prep_for_fixups): Detect section symbols based
4439 on either the lack of private data or the symbol flags. Do not
4440 munge section symbol names anymore -- they no longer confuse GDB.
4441 (som_begin_writing): Leave space for an exec header if writing
4443 (som_slurp_symbol_table): Recognize both forms of section symbol
4444 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4445 section symbols to be the name of the section they represent.
4446 Debugging symbols begin with "L$0\001", not just "L$".
4448 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4450 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4452 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4453 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4454 and bfd_is_local_label.
4456 * targets.c: Add new entries to the bfd_target structure.
4458 * bfd.c (bfd_copy_private_bfd_data): New definition.
4460 * section.c (bfd_copy_private_section_data): New definition.
4462 * syms.c (bfd_is_local_label): New definition.
4464 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4466 * libbfd.c (bfd_generic_is_local_label): New function.
4468 * *-core.c: Provide default definitions for new functions in
4469 the target vector which all point to bfd_false.
4471 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4472 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4473 Default new vectors for copying private backend data to bfd_true.
4474 Default new vector for determining if a symbol is a local label
4475 to bfd_generic_is_local_label.
4477 * som.c (som_bfd_copy_private_section_data): New function.
4478 (som_bfd_is_local_label): New function.
4479 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4481 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4483 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4485 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4487 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4490 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4491 Indent some of them to GNU standards.
4493 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4494 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4495 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4496 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4497 Update copyright years.
4499 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4501 * som.c (som_prep_for_fixups): A relocation involving the section
4502 symbol for the *ABS* section is really a relocation involving
4504 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4505 undefined symbols. Correctly distinguish between debugger symbols
4506 and section symbols.
4508 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4509 for spaces and subspaces.
4511 * som.c (som_bfd_count_ar_symbols): Fix typo.
4513 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4514 HAS_RELOC based on the object's magic number.
4515 (make_unique_section): Delete function. BFD and its users are
4516 prepared to handle multiple sections with the same name.
4517 (setup_sections): Allocate space on the BFD's obstack to hold
4518 section names. Use bfd_make_setion_anyway rather than the
4519 obsolete make_unique_section.
4520 (som_prep_headers): Choose the correct SOM magic number based
4522 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4524 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4526 * elf32-ppc.c: Renamed from elf32-powerpc.c.

4536 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4537 is always located at the start of the data section to allow
4538 recovery of the dynamic info from a stripped executable.

4542 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4544 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4545 cruft (like the #pragma alloca for AIX).
4546 In addition to that problem, the C alloca calls xmalloc, which
4547 means checking for being out of memory can't work right. The
4548 following changes remove all uses of alloca from BFD.
4549 * hosts/solaris2.h: Remove alloca cruft.
4550 * som.c: Replace alloca with a fixed size auto array.
4551 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

4553 sunos.c: Replace alloca with malloc and appropriate error checking and
4555 * linker.c: Replace alloca with obstack_alloc.
4556 * libbfd.h: Rebuilt.
4558 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4560 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4563 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4565 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4566 Elf*_Off typedefs by their expansion, the typedefs have been
4567 removed from include/elf/internal.h.
4568 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4569 SHT_PROGBITS section.
4571 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4573 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4579 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4580 return from bfd_seek indicates an error.
4581 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4582 TRAD_CORE_STACK_OFFSET.
4583 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4584 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4586 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4588 * som.[ch]: Do not include libhppa.h in som.c, instead include
4591 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4592 include it in elf32-hppa.h.
4594 * som.c (log2): Return -1 on error rather than aborting.
4595 (setup_sections): Bubble up an error from log2.
4597 * Changes to make HP C compiler happy in both traditional
4599 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4601 (bfd_som_set_section_attributes): Use unsigned int rather than
4602 unsigned char to avoid GNU-C extensions.
4603 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4604 or failure rather than aborting on failure.
4606 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4608 (bfd_som_attach_aux_hdr): Add prototype.
4609 (hppa_som-gen_reloc_type): Likewise.
4611 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4612 (hppa_look_for_stubs_in_section): Do not return false on failure
4613 until rest of code is ready to handle it. Abort for now.

4638 action in case where caller specified no argument relocation.
4639 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4640 right in the original relocation and the stub's relocation.
4642 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4643 unused symbols argument.
4645 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

4647 Set reloc->sym_ptr_ptr appropriately.
4648 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4649 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4650 argument. Use the output symbols when canonicalizing the relocs,
4651 creating them if necessary.
4653 * linker.c (_bfd_generic_link_output_symbols): Do not
4654 rebuild/clobber the output symbols if they already exist.
4656 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4658 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

4660 * bfd-in2.h: Rebuilt.
4662 * srec.c (hex_value): Always set to a size of 256 bytes.
4663 (srec_init): Cosmetic changes.
4665 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4668 PARAMize and staticize rest of functions. Delete unused
4669 functions. Delete unused/unnecessary arguments to some functions.
4670 Group static vars together. Abort for bad errors until we have
4671 error code propogation working. Work on spacing and indention.
4672 Add FIXMEs for unresolved problems. Use enums rather than
4673 #defines for lots of things. Merge two functions which build
4674 linker stubs into a single function (so they can easily share a
4675 ton of common code).
4677 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4679 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4680 avoid depending upon right shifts of signed numbers, and to
4681 correct handling of src_mask with lower bits zero.
4683 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.

4711 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
4712 (elf_hppa_tc_make_sections): Likewise.
4713 (elf_hppa_final_processing): Add extern decl.
4715 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4716 comments. PARAMize some static functions. Delete unused functions.
4717 Delete unused/unnecessary arguments to many functions. Group
4718 static vars together. Collapse common case statements together
4719 in many places. Use default case when possible instead of listing
4720 each case separately. Abort for bad errors until we get error
4721 code propogation working. Work on spacing and indention problems.
4722 Add FIXMEs for some unresolved problems. Delete hopelessly broken
4723 COMPLEX relocation support (it's never used anyway).
4724 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4725 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4726 (elf_hppa_tc_make_sections): Likewise.
4728 * format.c (bfd_check_format_matches): Initialize matching_vector
4729 to keep gcc -Wall quiet.

4739 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
4741 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

4762 * elfcode.h (elf_core_file_p): Check for core file e_machine match
4763 like in elf_object_p.

4767 * elfcode.h (alloca): Delete declaration.
4769 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
4770 number rather than HP9000S800_ID. Note som.c is careful
4771 to make sure CPU_PA_RISC1_0 is always defined.
4773 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)

5573 use get_value to get the symbol value and check for undefined
5575 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5576 undefined, look it up in the linker hash table.
5578 * aoutx.h (translate_symbol_table): The string index 0 has a

5603 The sparc (and possibly other?) NLM format requires a different
5604 way to write exports, so add a write_export field to the backend
5605 data (and set it to NULL for everything but the sparc).
