4321 bfd_link_hash_weak case to use .sc rather than .st.
4322 (ecoff_reloc_link_order): New function.
4323 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4325 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
4327 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
4330 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4331 bfd_zmalloc. Free a pointer, not a union.
4332 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4334 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4336 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4338 * som.c (bfd_section_from_som_symbol): Only to do the value
4339 comparison for function symbols within executables.
4341 * som.c (bfd_section_from_som_symbol): Renamed from
4342 som_section_from_subspace_index. Pass in a native SOM symbol.
4343 For executables, iterate through the sections to find out
4344 which contains the symbol's address rather than using the
4345 symbol_info field. (symbol_info has a different meaning for
4346 dynamicly linked executables.)
4348 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4351 * som.c (som_begin_writing): Fix braino (one call to align
4352 space/subspace data was done unconditionally rather than
4353 just for executables.)
4355 * som.c (som_begin_writing): Align text in all executables to
4356 make HPUX kernel happy. Fixes strip/objcopy for shared
4359 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4361 * som.c (som_begin_writing): Account for alignment needs of
4362 subspaces too when writing executables. Never request a negative
4363 bss size. Fixes some problems with demand paged executables,
4364 still having problems with pure executables and shared executables.
4366 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4368 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4369 bfd_zalloc for rawptr, because later on we may call free, not
4372 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4373 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4374 * cisco-core.c: New file.
4375 * Makefile.in: Change accordingly.
4376 * configure.in: Recognize cisco_core_vec.
4377 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4378 * targets.c: Add cisco_core_vec.
4379 * bfd-in2.h: Rebuilt.
4381 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4383 * som.h (som_copyable_section_data_struct): New structure
4384 containing all the private section information which needs
4385 to be copied from input section to output section during
4387 (som_section_data_struct): Remove several fields now in
4388 som_copyable_section_data_struct. Make the space and
4389 subspace dictionaries be pointers (to save space when
4390 only reading objects).
4392 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4393 some references changed. Allocate a copyable data stucture if
4394 none exists. Store info into the copyable data structure.
4395 (bfd_som_set_subsection_attributes): Likewise.
4396 (som_is_space, som_is_subspace, som_is_container): New functions.
4397 Use these instead of directly accessing private data.
4398 (som_prep_headers): Allocate space and subspace headers here.
4399 Fill in some fields in the space/subspace headers from the
4401 (som_bfd_copy_private_section_data): Only copy the stuff
4402 that we really need to make objcopy and strip work. Allocate
4403 the copy_data structure for the output bfd before copying.
4405 * som.h (struct som_exec_data): New structure to hold exec
4406 info that must be preserved when running objcopy/strip.
4407 (struct somdata): Add new "exec_data" field and accessor
4408 macro. Add some comments on how the various fields are used.
4409 (som_section_data_struct): Make is_space and is_subspace bitfields.
4410 Delete unused subspace_index. All references now use the
4411 target_index field within the section structure itself.
4413 * som.c (make_unique_section): Delete unused declaration.
4414 (som_bfd_copy_private_bfd_data): New function.
4415 (som_object_setup): Allocate space for and save exec information
4416 that needs to be copied during objcopy/strip.
4417 (som_mkobject): Do not allocate space for a file header here.
4418 It is not used when only reading SOM objects.
4419 (som_prep_headers): Allocate space for and attach a file header
4420 to the output bfd. For executables, use the saved system_id
4421 value rather than trying to guess the right value. Do not abort
4422 wwhen setting file_hdr->entry* for executables.
4423 (som_begin_writing): For executables, set the exec_entry and
4425 (som_copy_private_backend_section_data): Always return a value.
4427 * libhppa.h (PA_PAGESIZE): Define.
4429 * som.c (SOM_ALIGN): Define.
4430 (som_begin_writing): If writing an executable, initialize all
4431 fields in the exec header to zero. Update fields in the exec
4432 header as sizes of loadable subspaces are computed. Carefully
4433 preserve alignments when building executables. Actually write the
4434 exec after all the fields are filled in.
4436 * Better long-filename handling. Reads SOM ABI compliant extended
4437 names, but doesn't quite write compliant extended names yet.
4438 * som.c (som_slurp_extended_name_table): Delete function. The
4439 generic code will handle things correctly.
4440 (som_slurp_armap): Seek to the beginning of the next member.
4441 (normalize): New function.
4442 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4443 name table into account when computing the file offsets in the
4444 SOM dictionary. Make sure to align to an even boundary.
4445 (som_write_armap): Initialize the checksum to zero.
4446 (ar_maxchars): Fix. Opps.
4448 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4450 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4451 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4453 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4455 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4456 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4457 * bfd-in2.h: Regenerated.
4459 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4460 this was also named trad_unix_bfd_copy_private_bfd_data.
4462 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4464 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4465 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4466 returns NULL, it is not an error. It's possible that some of
4467 these checks are not necessary (because the size can never be
4468 zero), but putting in the checks is the conservative thing to do
4469 in light of the fact that some of these malloc calls replaced
4470 unchecked alloca calls, in which a zero argument would work fine.
4472 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4474 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4475 duplicate definition.
4476 (osf_core_bfd_is_local_label): Define.
4478 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4479 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4480 failure indication, it merely means there are no relocs.
4482 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4483 after NAME, since SunOS /bin/cc can't handle it.
4485 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4487 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4488 From sukes@glue.umd.edu (Tasuki Hirata).
4490 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4492 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4493 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4494 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4496 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4498 * som.c (som_prep_for_fixups): Detect section symbols based
4499 on either the lack of private data or the symbol flags. Do not
4500 munge section symbol names anymore -- they no longer confuse GDB.
4501 (som_begin_writing): Leave space for an exec header if writing
4503 (som_slurp_symbol_table): Recognize both forms of section symbol
4504 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4505 section symbols to be the name of the section they represent.
4506 Debugging symbols begin with "L$0\001", not just "L$".
4508 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4510 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4512 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4513 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4514 and bfd_is_local_label.
4516 * targets.c: Add new entries to the bfd_target structure.
4518 * bfd.c (bfd_copy_private_bfd_data): New definition.
4520 * section.c (bfd_copy_private_section_data): New definition.
4522 * syms.c (bfd_is_local_label): New definition.
4524 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4526 * libbfd.c (bfd_generic_is_local_label): New function.
4528 * *-core.c: Provide default definitions for new functions in
4529 the target vector which all point to bfd_false.
4531 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4532 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4533 Default new vectors for copying private backend data to bfd_true.
4534 Default new vector for determining if a symbol is a local label
4535 to bfd_generic_is_local_label.
4537 * som.c (som_bfd_copy_private_section_data): New function.
4538 (som_bfd_is_local_label): New function.
4539 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4541 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4543 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4545 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4547 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4550 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4551 Indent some of them to GNU standards.
4553 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4554 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4555 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4556 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4557 Update copyright years.
4559 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4561 * som.c (som_prep_for_fixups): A relocation involving the section
4562 symbol for the *ABS* section is really a relocation involving
4564 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4565 undefined symbols. Correctly distinguish between debugger symbols
4566 and section symbols.
4568 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4569 for spaces and subspaces.
4571 * som.c (som_bfd_count_ar_symbols): Fix typo.
4573 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4574 HAS_RELOC based on the object's magic number.
4575 (make_unique_section): Delete function. BFD and its users are
4576 prepared to handle multiple sections with the same name.
4577 (setup_sections): Allocate space on the BFD's obstack to hold
4578 section names. Use bfd_make_setion_anyway rather than the
4579 obsolete make_unique_section.
4580 (som_prep_headers): Choose the correct SOM magic number based
4582 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4584 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4586 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4587 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4588 * Makefile.in, configure.in: Corresponding changes.
4590 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4592 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
4594 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4596 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4597 is always located at the start of the data section to allow
4598 recovery of the dynamic info from a stripped executable.
4599 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4602 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4604 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4605 cruft (like the #pragma alloca for AIX).
4606 In addition to that problem, the C alloca calls xmalloc, which
4607 means checking for being out of memory can't work right. The
4608 following changes remove all uses of alloca from BFD.
4609 * hosts/solaris2.h: Remove alloca cruft.
4610 * som.c: Replace alloca with a fixed size auto array.
4611 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4612 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4613 sunos.c: Replace alloca with malloc and appropriate error checking and
4615 * linker.c: Replace alloca with obstack_alloc.
4616 * libbfd.h: Rebuilt.
4618 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4620 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4623 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4625 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4626 Elf*_Off typedefs by their expansion, the typedefs have been
4627 removed from include/elf/internal.h.
4628 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4629 SHT_PROGBITS section.
4631 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4633 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4637 * configure.host: Recognize i[34]86-sequent-*.
4639 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4640 return from bfd_seek indicates an error.
4641 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4642 TRAD_CORE_STACK_OFFSET.
4643 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4644 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4646 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4648 * som.[ch]: Do not include libhppa.h in som.c, instead include
4651 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4652 include it in elf32-hppa.h.
4654 * som.c (log2): Return -1 on error rather than aborting.
4655 (setup_sections): Bubble up an error from log2.
4657 * Changes to make HP C compiler happy in both traditional
4659 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4661 (bfd_som_set_section_attributes): Use unsigned int rather than
4662 unsigned char to avoid GNU-C extensions.
4663 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4664 or failure rather than aborting on failure.
4666 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4668 (bfd_som_attach_aux_hdr): Add prototype.
4669 (hppa_som-gen_reloc_type): Likewise.
4671 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4672 (hppa_look_for_stubs_in_section): Do not return false on failure
4673 until rest of code is ready to handle it. Abort for now.

4677 * bfd-in2.h: Rebuilt.
4679 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

4685 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
4687 * config.bfd : Add i386-os9k.
4688 * config/i386-os9k.mt : Newly add os9k target makefile.
4690 * i386os9k.c : new file to handle os9k format bfd.
4691 * Makefile.in : Handle new file i386os9k.c
4692 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
4693 * cache.c : Initialize cache_sentinel to 0.

4697 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
4698 action in case where caller specified no argument relocation.
4699 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4700 right in the original relocation and the stub's relocation.
4702 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4703 unused symbols argument.
4705 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4706 than asymbol * for original target symbol. All callers changed.
4707 Set reloc->sym_ptr_ptr appropriately.
4708 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4709 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4710 argument. Use the output symbols when canonicalizing the relocs,
4711 creating them if necessary.
4713 * linker.c (_bfd_generic_link_output_symbols): Do not
4714 rebuild/clobber the output symbols if they already exist.
4716 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4718 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4719 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4720 * bfd-in2.h: Rebuilt.
4722 * srec.c (hex_value): Always set to a size of 256 bytes.
4723 (srec_init): Cosmetic changes.
4725 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4727 * elf32-hppa.c: Second half of major cleanup. More comments,
4728 PARAMize and staticize rest of functions. Delete unused
4729 functions. Delete unused/unnecessary arguments to some functions.
4730 Group static vars together. Abort for bad errors until we have
4731 error code propogation working. Work on spacing and indention.
4732 Add FIXMEs for unresolved problems. Use enums rather than
4733 #defines for lots of things. Merge two functions which build
4734 linker stubs into a single function (so they can easily share a
4735 ton of common code).
4737 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4739 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4740 avoid depending upon right shifts of signed numbers, and to
4741 correct handling of src_mask with lower bits zero.
4743 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
4744 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

4751 (write_shdrs_and_ehdr): Make count unsigned.
4752 (assign_file_positions_for_relocs): Make i unsigned.
4753 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
4754 (section_from_elf_index): Make index argument unsigned.
4756 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
4758 * elfcode.h: Don't include assert.h.

4769 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
4771 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
4772 (elf_hppa_tc_make_sections): Likewise.
4773 (elf_hppa_final_processing): Add extern decl.
4775 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4776 comments. PARAMize some static functions. Delete unused functions.
4777 Delete unused/unnecessary arguments to many functions. Group
4778 static vars together. Collapse common case statements together
4779 in many places. Use default case when possible instead of listing

5633 use get_value to get the symbol value and check for undefined
5635 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5636 undefined, look it up in the linker hash table.
5638 * aoutx.h (translate_symbol_table): The string index 0 has a

5663 The sparc (and possibly other?) NLM format requires a different
5664 way to write exports, so add a write_export field to the backend
