718 symbol when no dynamic object was seen, initialize the contents of
719 the .got section. For a GOT reloc against a local symbol, only

4326 bfd_link_hash_weak case to use .sc rather than .st.
4327 (ecoff_reloc_link_order): New function.
4328 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4330 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
4332 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
4335 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4336 bfd_zmalloc. Free a pointer, not a union.
4337 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4339 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4341 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4343 * som.c (bfd_section_from_som_symbol): Only to do the value
4344 comparison for function symbols within executables.
4346 * som.c (bfd_section_from_som_symbol): Renamed from
4347 som_section_from_subspace_index. Pass in a native SOM symbol.
4348 For executables, iterate through the sections to find out
4349 which contains the symbol's address rather than using the
4350 symbol_info field. (symbol_info has a different meaning for
4351 dynamicly linked executables.)
4353 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4356 * som.c (som_begin_writing): Fix braino (one call to align
4357 space/subspace data was done unconditionally rather than
4358 just for executables.)
4360 * som.c (som_begin_writing): Align text in all executables to
4361 make HPUX kernel happy. Fixes strip/objcopy for shared
4364 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4366 * som.c (som_begin_writing): Account for alignment needs of
4367 subspaces too when writing executables. Never request a negative
4368 bss size. Fixes some problems with demand paged executables,
4369 still having problems with pure executables and shared executables.
4371 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4373 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4374 bfd_zalloc for rawptr, because later on we may call free, not
4377 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4378 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4379 * cisco-core.c: New file.
4380 * Makefile.in: Change accordingly.
4381 * configure.in: Recognize cisco_core_vec.
4382 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4383 * targets.c: Add cisco_core_vec.
4384 * bfd-in2.h: Rebuilt.
4386 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4388 * som.h (som_copyable_section_data_struct): New structure
4389 containing all the private section information which needs
4390 to be copied from input section to output section during
4392 (som_section_data_struct): Remove several fields now in
4393 som_copyable_section_data_struct. Make the space and
4394 subspace dictionaries be pointers (to save space when
4395 only reading objects).
4397 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4398 some references changed. Allocate a copyable data stucture if
4399 none exists. Store info into the copyable data structure.
4400 (bfd_som_set_subsection_attributes): Likewise.
4401 (som_is_space, som_is_subspace, som_is_container): New functions.
4402 Use these instead of directly accessing private data.
4403 (som_prep_headers): Allocate space and subspace headers here.
4404 Fill in some fields in the space/subspace headers from the
4406 (som_bfd_copy_private_section_data): Only copy the stuff
4407 that we really need to make objcopy and strip work. Allocate
4408 the copy_data structure for the output bfd before copying.
4410 * som.h (struct som_exec_data): New structure to hold exec
4411 info that must be preserved when running objcopy/strip.
4412 (struct somdata): Add new "exec_data" field and accessor
4413 macro. Add some comments on how the various fields are used.
4414 (som_section_data_struct): Make is_space and is_subspace bitfields.
4415 Delete unused subspace_index. All references now use the
4416 target_index field within the section structure itself.
4418 * som.c (make_unique_section): Delete unused declaration.
4419 (som_bfd_copy_private_bfd_data): New function.
4420 (som_object_setup): Allocate space for and save exec information
4421 that needs to be copied during objcopy/strip.
4422 (som_mkobject): Do not allocate space for a file header here.
4423 It is not used when only reading SOM objects.
4424 (som_prep_headers): Allocate space for and attach a file header
4425 to the output bfd. For executables, use the saved system_id
4426 value rather than trying to guess the right value. Do not abort
4427 wwhen setting file_hdr->entry* for executables.
4428 (som_begin_writing): For executables, set the exec_entry and
4430 (som_copy_private_backend_section_data): Always return a value.
4432 * libhppa.h (PA_PAGESIZE): Define.
4434 * som.c (SOM_ALIGN): Define.
4435 (som_begin_writing): If writing an executable, initialize all
4436 fields in the exec header to zero. Update fields in the exec
4437 header as sizes of loadable subspaces are computed. Carefully
4438 preserve alignments when building executables. Actually write the
4439 exec after all the fields are filled in.
4441 * Better long-filename handling. Reads SOM ABI compliant extended
4442 names, but doesn't quite write compliant extended names yet.
4443 * som.c (som_slurp_extended_name_table): Delete function. The
4444 generic code will handle things correctly.
4445 (som_slurp_armap): Seek to the beginning of the next member.
4446 (normalize): New function.
4447 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4448 name table into account when computing the file offsets in the
4449 SOM dictionary. Make sure to align to an even boundary.
4450 (som_write_armap): Initialize the checksum to zero.
4451 (ar_maxchars): Fix. Opps.
4453 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4455 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4456 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4458 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4460 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4461 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4462 * bfd-in2.h: Regenerated.
4464 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4465 this was also named trad_unix_bfd_copy_private_bfd_data.
4467 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4469 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4470 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4471 returns NULL, it is not an error. It's possible that some of
4472 these checks are not necessary (because the size can never be
4473 zero), but putting in the checks is the conservative thing to do
4474 in light of the fact that some of these malloc calls replaced
4475 unchecked alloca calls, in which a zero argument would work fine.
4477 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4479 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4480 duplicate definition.
4481 (osf_core_bfd_is_local_label): Define.
4483 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4484 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4485 failure indication, it merely means there are no relocs.
4487 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4488 after NAME, since SunOS /bin/cc can't handle it.
4490 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4492 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4493 From sukes@glue.umd.edu (Tasuki Hirata).
4495 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4497 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4498 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4499 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4501 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4503 * som.c (som_prep_for_fixups): Detect section symbols based
4504 on either the lack of private data or the symbol flags. Do not
4505 munge section symbol names anymore -- they no longer confuse GDB.
4506 (som_begin_writing): Leave space for an exec header if writing
4508 (som_slurp_symbol_table): Recognize both forms of section symbol
4509 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4510 section symbols to be the name of the section they represent.
4511 Debugging symbols begin with "L$0\001", not just "L$".
4513 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4515 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4517 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4518 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4519 and bfd_is_local_label.
4521 * targets.c: Add new entries to the bfd_target structure.
4523 * bfd.c (bfd_copy_private_bfd_data): New definition.
4525 * section.c (bfd_copy_private_section_data): New definition.
4527 * syms.c (bfd_is_local_label): New definition.
4529 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4531 * libbfd.c (bfd_generic_is_local_label): New function.
4533 * *-core.c: Provide default definitions for new functions in
4534 the target vector which all point to bfd_false.
4536 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4537 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4538 Default new vectors for copying private backend data to bfd_true.
4539 Default new vector for determining if a symbol is a local label
4540 to bfd_generic_is_local_label.
4542 * som.c (som_bfd_copy_private_section_data): New function.
4543 (som_bfd_is_local_label): New function.
4544 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4546 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4548 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4550 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4552 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4555 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4556 Indent some of them to GNU standards.
4558 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4559 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4560 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4561 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4562 Update copyright years.
4564 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4566 * som.c (som_prep_for_fixups): A relocation involving the section
4567 symbol for the *ABS* section is really a relocation involving
4569 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4570 undefined symbols. Correctly distinguish between debugger symbols
4571 and section symbols.
4573 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4574 for spaces and subspaces.
4576 * som.c (som_bfd_count_ar_symbols): Fix typo.
4578 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4579 HAS_RELOC based on the object's magic number.
4580 (make_unique_section): Delete function. BFD and its users are
4581 prepared to handle multiple sections with the same name.
4582 (setup_sections): Allocate space on the BFD's obstack to hold
4583 section names. Use bfd_make_setion_anyway rather than the
4584 obsolete make_unique_section.
4585 (som_prep_headers): Choose the correct SOM magic number based
4587 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4589 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4591 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4592 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4593 * Makefile.in, configure.in: Corresponding changes.
4595 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4597 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
4599 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4601 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4602 is always located at the start of the data section to allow
4603 recovery of the dynamic info from a stripped executable.
4604 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4607 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4609 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4610 cruft (like the #pragma alloca for AIX).
4611 In addition to that problem, the C alloca calls xmalloc, which
4612 means checking for being out of memory can't work right. The
4613 following changes remove all uses of alloca from BFD.
4614 * hosts/solaris2.h: Remove alloca cruft.
4615 * som.c: Replace alloca with a fixed size auto array.
4616 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4617 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4618 sunos.c: Replace alloca with malloc and appropriate error checking and
4620 * linker.c: Replace alloca with obstack_alloc.
4621 * libbfd.h: Rebuilt.
4623 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4625 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4628 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4630 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4631 Elf*_Off typedefs by their expansion, the typedefs have been
4632 removed from include/elf/internal.h.
4633 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4634 SHT_PROGBITS section.
4636 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4638 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4642 * configure.host: Recognize i[34]86-sequent-*.
4644 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4645 return from bfd_seek indicates an error.
4646 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4647 TRAD_CORE_STACK_OFFSET.
4648 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4649 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4651 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4653 * som.[ch]: Do not include libhppa.h in som.c, instead include
4656 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4657 include it in elf32-hppa.h.
4659 * som.c (log2): Return -1 on error rather than aborting.
4660 (setup_sections): Bubble up an error from log2.
4662 * Changes to make HP C compiler happy in both traditional
4664 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4666 (bfd_som_set_section_attributes): Use unsigned int rather than
4667 unsigned char to avoid GNU-C extensions.
4668 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4669 or failure rather than aborting on failure.
4671 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4673 (bfd_som_attach_aux_hdr): Add prototype.
4674 (hppa_som-gen_reloc_type): Likewise.
4676 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4677 (hppa_look_for_stubs_in_section): Do not return false on failure
4678 until rest of code is ready to handle it. Abort for now.
4680 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4682 * bfd-in2.h: Rebuilt.
4684 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
4686 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

4690 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
4692 * config.bfd : Add i386-os9k.
4693 * config/i386-os9k.mt : Newly add os9k target makefile.
4695 * i386os9k.c : new file to handle os9k format bfd.
4696 * Makefile.in : Handle new file i386os9k.c
4697 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
4698 * cache.c : Initialize cache_sentinel to 0.

4702 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
4703 action in case where caller specified no argument relocation.
4704 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4705 right in the original relocation and the stub's relocation.
4707 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4708 unused symbols argument.
4710 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4711 than asymbol * for original target symbol. All callers changed.
4712 Set reloc->sym_ptr_ptr appropriately.
4713 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4714 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4715 argument. Use the output symbols when canonicalizing the relocs,
4716 creating them if necessary.
4718 * linker.c (_bfd_generic_link_output_symbols): Do not
4719 rebuild/clobber the output symbols if they already exist.
4721 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4723 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4724 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4725 * bfd-in2.h: Rebuilt.
4727 * srec.c (hex_value): Always set to a size of 256 bytes.
4728 (srec_init): Cosmetic changes.
4730 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4732 * elf32-hppa.c: Second half of major cleanup. More comments,
4733 PARAMize and staticize rest of functions. Delete unused
4734 functions. Delete unused/unnecessary arguments to some functions.
4735 Group static vars together. Abort for bad errors until we have
4736 error code propogation working. Work on spacing and indention.
4737 Add FIXMEs for unresolved problems. Use enums rather than
4738 #defines for lots of things. Merge two functions which build
4739 linker stubs into a single function (so they can easily share a
4740 ton of common code).
4742 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4744 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4745 avoid depending upon right shifts of signed numbers, and to
4746 correct handling of src_mask with lower bits zero.
4748 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
4749 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

4756 (write_shdrs_and_ehdr): Make count unsigned.
4757 (assign_file_positions_for_relocs): Make i unsigned.
4758 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
4759 (section_from_elf_index): Make index argument unsigned.
4761 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
4763 * elfcode.h: Don't include assert.h.
4764 (swap_out_syms): Use BFD_ASSERT rather than assert.

4769 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
4772 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4774 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
4776 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
4777 (elf_hppa_tc_make_sections): Likewise.
4778 (elf_hppa_final_processing): Add extern decl.
4780 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4781 comments. PARAMize some static functions. Delete unused functions.
4782 Delete unused/unnecessary arguments to many functions. Group
4783 static vars together. Collapse common case statements together
4784 in many places. Use default case when possible instead of listing

5638 use get_value to get the symbol value and check for undefined
5640 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5641 undefined, look it up in the linker hash table.
5643 * aoutx.h (translate_symbol_table): The string index 0 has a

5668 The sparc (and possibly other?) NLM format requires a different
5669 way to write exports, so add a write_export field to the backend

5903 * nlmcode.h (nlm_object_p): If we can't read the fixed header,
