4322 bfd_zalloc for rawptr, because later on we may call free, not
4325 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4326 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4327 * cisco-core.c: New file.
4328 * Makefile.in: Change accordingly.
4329 * configure.in: Recognize cisco_core_vec.
4330 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4331 * targets.c: Add cisco_core_vec.
4332 * bfd-in2.h: Rebuilt.
4334 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4336 * som.h (som_copyable_section_data_struct): New structure
4337 containing all the private section information which needs
4338 to be copied from input section to output section during
4340 (som_section_data_struct): Remove several fields now in
4341 som_copyable_section_data_struct. Make the space and
4342 subspace dictionaries be pointers (to save space when
4343 only reading objects).
4345 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4346 some references changed. Allocate a copyable data stucture if
4347 none exists. Store info into the copyable data structure.
4348 (bfd_som_set_subsection_attributes): Likewise.
4349 (som_is_space, som_is_subspace, som_is_container): New functions.
4350 Use these instead of directly accessing private data.
4351 (som_prep_headers): Allocate space and subspace headers here.
4352 Fill in some fields in the space/subspace headers from the
4354 (som_bfd_copy_private_section_data): Only copy the stuff
4355 that we really need to make objcopy and strip work. Allocate
4356 the copy_data structure for the output bfd before copying.
4358 * som.h (struct som_exec_data): New structure to hold exec
4359 info that must be preserved when running objcopy/strip.
4360 (struct somdata): Add new "exec_data" field and accessor
4361 macro. Add some comments on how the various fields are used.
4362 (som_section_data_struct): Make is_space and is_subspace bitfields.
4363 Delete unused subspace_index. All references now use the
4364 target_index field within the section structure itself.
4366 * som.c (make_unique_section): Delete unused declaration.
4367 (som_bfd_copy_private_bfd_data): New function.
4368 (som_object_setup): Allocate space for and save exec information
4369 that needs to be copied during objcopy/strip.
4370 (som_mkobject): Do not allocate space for a file header here.
4371 It is not used when only reading SOM objects.
4372 (som_prep_headers): Allocate space for and attach a file header
4373 to the output bfd. For executables, use the saved system_id
4374 value rather than trying to guess the right value. Do not abort
4375 wwhen setting file_hdr->entry* for executables.
4376 (som_begin_writing): For executables, set the exec_entry and
4378 (som_copy_private_backend_section_data): Always return a value.
4380 * libhppa.h (PA_PAGESIZE): Define.
4382 * som.c (SOM_ALIGN): Define.
4383 (som_begin_writing): If writing an executable, initialize all
4384 fields in the exec header to zero. Update fields in the exec
4385 header as sizes of loadable subspaces are computed. Carefully
4386 preserve alignments when building executables. Actually write the
4387 exec after all the fields are filled in.
4389 * Better long-filename handling. Reads SOM ABI compliant extended
4390 names, but doesn't quite write compliant extended names yet.
4391 * som.c (som_slurp_extended_name_table): Delete function. The
4392 generic code will handle things correctly.
4393 (som_slurp_armap): Seek to the beginning of the next member.
4394 (normalize): New function.
4395 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4396 name table into account when computing the file offsets in the
4397 SOM dictionary. Make sure to align to an even boundary.
4398 (som_write_armap): Initialize the checksum to zero.
4399 (ar_maxchars): Fix. Opps.
4401 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4403 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4404 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4406 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4408 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4409 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4410 * bfd-in2.h: Regenerated.
4412 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4413 this was also named trad_unix_bfd_copy_private_bfd_data.
4415 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4417 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4418 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4419 returns NULL, it is not an error. It's possible that some of
4420 these checks are not necessary (because the size can never be
4421 zero), but putting in the checks is the conservative thing to do
4422 in light of the fact that some of these malloc calls replaced
4423 unchecked alloca calls, in which a zero argument would work fine.
4425 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4427 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4428 duplicate definition.
4429 (osf_core_bfd_is_local_label): Define.
4431 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4432 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4433 failure indication, it merely means there are no relocs.
4435 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4436 after NAME, since SunOS /bin/cc can't handle it.
4438 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4440 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4441 From sukes@glue.umd.edu (Tasuki Hirata).
4443 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4445 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4446 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4447 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4449 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4451 * som.c (som_prep_for_fixups): Detect section symbols based
4452 on either the lack of private data or the symbol flags. Do not
4453 munge section symbol names anymore -- they no longer confuse GDB.
4454 (som_begin_writing): Leave space for an exec header if writing
4456 (som_slurp_symbol_table): Recognize both forms of section symbol
4457 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4458 section symbols to be the name of the section they represent.
4459 Debugging symbols begin with "L$0\001", not just "L$".
4461 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4463 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4465 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4466 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4467 and bfd_is_local_label.
4469 * targets.c: Add new entries to the bfd_target structure.
4471 * bfd.c (bfd_copy_private_bfd_data): New definition.
4473 * section.c (bfd_copy_private_section_data): New definition.
4475 * syms.c (bfd_is_local_label): New definition.
4477 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4479 * libbfd.c (bfd_generic_is_local_label): New function.
4481 * *-core.c: Provide default definitions for new functions in
4482 the target vector which all point to bfd_false.
4484 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4485 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4486 Default new vectors for copying private backend data to bfd_true.
4487 Default new vector for determining if a symbol is a local label
4488 to bfd_generic_is_local_label.
4490 * som.c (som_bfd_copy_private_section_data): New function.
4491 (som_bfd_is_local_label): New function.
4492 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4494 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4496 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4498 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4500 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4503 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4504 Indent some of them to GNU standards.
4506 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4507 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4508 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4509 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4510 Update copyright years.
4512 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4514 * som.c (som_prep_for_fixups): A relocation involving the section
4515 symbol for the *ABS* section is really a relocation involving
4517 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4518 undefined symbols. Correctly distinguish between debugger symbols
4519 and section symbols.
4521 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4522 for spaces and subspaces.
4524 * som.c (som_bfd_count_ar_symbols): Fix typo.
4526 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4527 HAS_RELOC based on the object's magic number.
4528 (make_unique_section): Delete function. BFD and its users are
4529 prepared to handle multiple sections with the same name.
4530 (setup_sections): Allocate space on the BFD's obstack to hold
4531 section names. Use bfd_make_setion_anyway rather than the
4532 obsolete make_unique_section.
4533 (som_prep_headers): Choose the correct SOM magic number based
4535 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4537 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4539 * elf32-ppc.c: Renamed from elf32-powerpc.c.

4549 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4550 is always located at the start of the data section to allow
4551 recovery of the dynamic info from a stripped executable.
4552 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4555 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4557 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4558 cruft (like the #pragma alloca for AIX).
4559 In addition to that problem, the C alloca calls xmalloc, which
4560 means checking for being out of memory can't work right. The
4561 following changes remove all uses of alloca from BFD.
4562 * hosts/solaris2.h: Remove alloca cruft.
4563 * som.c: Replace alloca with a fixed size auto array.
4564 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4565 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4566 sunos.c: Replace alloca with malloc and appropriate error checking and
4568 * linker.c: Replace alloca with obstack_alloc.
4569 * libbfd.h: Rebuilt.
4571 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4573 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4576 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4578 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4579 Elf*_Off typedefs by their expansion, the typedefs have been
4580 removed from include/elf/internal.h.
4581 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4582 SHT_PROGBITS section.
4584 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4586 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4592 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4593 return from bfd_seek indicates an error.
4594 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4595 TRAD_CORE_STACK_OFFSET.
4596 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4597 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4599 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4601 * som.[ch]: Do not include libhppa.h in som.c, instead include
4604 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4605 include it in elf32-hppa.h.
4607 * som.c (log2): Return -1 on error rather than aborting.
4608 (setup_sections): Bubble up an error from log2.
4610 * Changes to make HP C compiler happy in both traditional
4612 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4614 (bfd_som_set_section_attributes): Use unsigned int rather than
4615 unsigned char to avoid GNU-C extensions.
4616 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4617 or failure rather than aborting on failure.
4619 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4621 (bfd_som_attach_aux_hdr): Add prototype.
4622 (hppa_som-gen_reloc_type): Likewise.

4651 action in case where caller specified no argument relocation.
4652 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4653 right in the original relocation and the stub's relocation.
4655 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4656 unused symbols argument.
4658 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

4660 Set reloc->sym_ptr_ptr appropriately.
4661 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4662 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4663 argument. Use the output symbols when canonicalizing the relocs,
4664 creating them if necessary.
4666 * linker.c (_bfd_generic_link_output_symbols): Do not
4667 rebuild/clobber the output symbols if they already exist.
4669 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4671 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

4673 * bfd-in2.h: Rebuilt.
4675 * srec.c (hex_value): Always set to a size of 256 bytes.
4676 (srec_init): Cosmetic changes.
4678 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4680 * elf32-hppa.c: Second half of major cleanup. More comments,
4681 PARAMize and staticize rest of functions. Delete unused
4682 functions. Delete unused/unnecessary arguments to some functions.
4683 Group static vars together. Abort for bad errors until we have
4684 error code propogation working. Work on spacing and indention.
4685 Add FIXMEs for unresolved problems. Use enums rather than
4686 #defines for lots of things. Merge two functions which build
4687 linker stubs into a single function (so they can easily share a
4688 ton of common code).
4690 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4692 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4693 avoid depending upon right shifts of signed numbers, and to
4694 correct handling of src_mask with lower bits zero.
4696 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
4697 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

4722 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
4724 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
4725 (elf_hppa_tc_make_sections): Likewise.
4726 (elf_hppa_final_processing): Add extern decl.
4728 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4729 comments. PARAMize some static functions. Delete unused functions.
4730 Delete unused/unnecessary arguments to many functions. Group
4731 static vars together. Collapse common case statements together
4732 in many places. Use default case when possible instead of listing
4733 each case separately. Abort for bad errors until we get error
4734 code propogation working. Work on spacing and indention problems.
4735 Add FIXMEs for some unresolved problems. Delete hopelessly broken
4736 COMPLEX relocation support (it's never used anyway).
4737 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4738 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4739 (elf_hppa_tc_make_sections): Likewise.
4741 * format.c (bfd_check_format_matches): Initialize matching_vector

4752 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
4754 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

5586 use get_value to get the symbol value and check for undefined
5588 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5589 undefined, look it up in the linker hash table.
5591 * aoutx.h (translate_symbol_table): The string index 0 has a

5616 The sparc (and possibly other?) NLM format requires a different
5617 way to write exports, so add a write_export field to the backend
5618 data (and set it to NULL for everything but the sparc).
