4326 call to _bfd_generic_link_add_one_symbol.
4327 (ecoff_bfd_final_link): Account for link_order relocs when
4328 allocating space for relocations. Handle them in link_order loop.
4329 (ecoff_link_write_external): Set the storage class of a defined
4330 linker created symbol based on the section it is in. Correct
4331 bfd_link_hash_weak case to use .sc rather than .st.
4332 (ecoff_reloc_link_order): New function.
4333 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4335 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
4337 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
4340 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4341 bfd_zmalloc. Free a pointer, not a union.
4342 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4344 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4346 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4348 * som.c (bfd_section_from_som_symbol): Only to do the value
4349 comparison for function symbols within executables.
4351 * som.c (bfd_section_from_som_symbol): Renamed from
4352 som_section_from_subspace_index. Pass in a native SOM symbol.
4353 For executables, iterate through the sections to find out
4354 which contains the symbol's address rather than using the
4355 symbol_info field. (symbol_info has a different meaning for
4356 dynamicly linked executables.)
4358 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4361 * som.c (som_begin_writing): Fix braino (one call to align
4362 space/subspace data was done unconditionally rather than
4363 just for executables.)
4365 * som.c (som_begin_writing): Align text in all executables to
4366 make HPUX kernel happy. Fixes strip/objcopy for shared
4369 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4371 * som.c (som_begin_writing): Account for alignment needs of
4372 subspaces too when writing executables. Never request a negative
4373 bss size. Fixes some problems with demand paged executables,
4374 still having problems with pure executables and shared executables.
4376 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4378 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4379 bfd_zalloc for rawptr, because later on we may call free, not
4382 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4383 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4384 * cisco-core.c: New file.
4385 * Makefile.in: Change accordingly.
4386 * configure.in: Recognize cisco_core_vec.
4387 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4388 * targets.c: Add cisco_core_vec.
4389 * bfd-in2.h: Rebuilt.
4391 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4393 * som.h (som_copyable_section_data_struct): New structure
4394 containing all the private section information which needs
4395 to be copied from input section to output section during
4397 (som_section_data_struct): Remove several fields now in
4398 som_copyable_section_data_struct. Make the space and
4399 subspace dictionaries be pointers (to save space when
4400 only reading objects).
4402 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4403 some references changed. Allocate a copyable data stucture if
4404 none exists. Store info into the copyable data structure.
4405 (bfd_som_set_subsection_attributes): Likewise.
4406 (som_is_space, som_is_subspace, som_is_container): New functions.
4407 Use these instead of directly accessing private data.
4408 (som_prep_headers): Allocate space and subspace headers here.
4409 Fill in some fields in the space/subspace headers from the
4411 (som_bfd_copy_private_section_data): Only copy the stuff
4412 that we really need to make objcopy and strip work. Allocate
4413 the copy_data structure for the output bfd before copying.
4415 * som.h (struct som_exec_data): New structure to hold exec
4416 info that must be preserved when running objcopy/strip.
4417 (struct somdata): Add new "exec_data" field and accessor
4418 macro. Add some comments on how the various fields are used.
4419 (som_section_data_struct): Make is_space and is_subspace bitfields.
4420 Delete unused subspace_index. All references now use the
4421 target_index field within the section structure itself.
4423 * som.c (make_unique_section): Delete unused declaration.
4424 (som_bfd_copy_private_bfd_data): New function.
4425 (som_object_setup): Allocate space for and save exec information
4426 that needs to be copied during objcopy/strip.
4427 (som_mkobject): Do not allocate space for a file header here.
4428 It is not used when only reading SOM objects.
4429 (som_prep_headers): Allocate space for and attach a file header
4430 to the output bfd. For executables, use the saved system_id
4431 value rather than trying to guess the right value. Do not abort
4432 wwhen setting file_hdr->entry* for executables.
4433 (som_begin_writing): For executables, set the exec_entry and
4435 (som_copy_private_backend_section_data): Always return a value.
4437 * libhppa.h (PA_PAGESIZE): Define.
4439 * som.c (SOM_ALIGN): Define.
4440 (som_begin_writing): If writing an executable, initialize all
4441 fields in the exec header to zero. Update fields in the exec
4442 header as sizes of loadable subspaces are computed. Carefully
4443 preserve alignments when building executables. Actually write the
4444 exec after all the fields are filled in.
4446 * Better long-filename handling. Reads SOM ABI compliant extended
4447 names, but doesn't quite write compliant extended names yet.
4448 * som.c (som_slurp_extended_name_table): Delete function. The
4449 generic code will handle things correctly.
4450 (som_slurp_armap): Seek to the beginning of the next member.
4451 (normalize): New function.
4452 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4453 name table into account when computing the file offsets in the
4454 SOM dictionary. Make sure to align to an even boundary.
4455 (som_write_armap): Initialize the checksum to zero.
4456 (ar_maxchars): Fix. Opps.
4458 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4460 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4461 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4463 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4465 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4466 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4467 * bfd-in2.h: Regenerated.
4469 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4470 this was also named trad_unix_bfd_copy_private_bfd_data.
4472 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4474 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4475 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4476 returns NULL, it is not an error. It's possible that some of
4477 these checks are not necessary (because the size can never be
4478 zero), but putting in the checks is the conservative thing to do
4479 in light of the fact that some of these malloc calls replaced
4480 unchecked alloca calls, in which a zero argument would work fine.
4482 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4484 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4485 duplicate definition.
4486 (osf_core_bfd_is_local_label): Define.
4488 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4489 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4490 failure indication, it merely means there are no relocs.
4492 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4493 after NAME, since SunOS /bin/cc can't handle it.
4495 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4497 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4498 From sukes@glue.umd.edu (Tasuki Hirata).
4500 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4502 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4503 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4504 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4506 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4508 * som.c (som_prep_for_fixups): Detect section symbols based
4509 on either the lack of private data or the symbol flags. Do not
4510 munge section symbol names anymore -- they no longer confuse GDB.
4511 (som_begin_writing): Leave space for an exec header if writing
4513 (som_slurp_symbol_table): Recognize both forms of section symbol
4514 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4515 section symbols to be the name of the section they represent.
4516 Debugging symbols begin with "L$0\001", not just "L$".
4518 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4520 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4522 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4523 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4524 and bfd_is_local_label.
4526 * targets.c: Add new entries to the bfd_target structure.
4528 * bfd.c (bfd_copy_private_bfd_data): New definition.
4530 * section.c (bfd_copy_private_section_data): New definition.
4532 * syms.c (bfd_is_local_label): New definition.
4534 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4536 * libbfd.c (bfd_generic_is_local_label): New function.
4538 * *-core.c: Provide default definitions for new functions in
4539 the target vector which all point to bfd_false.
4541 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4542 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4543 Default new vectors for copying private backend data to bfd_true.
4544 Default new vector for determining if a symbol is a local label
4545 to bfd_generic_is_local_label.
4547 * som.c (som_bfd_copy_private_section_data): New function.
4548 (som_bfd_is_local_label): New function.
4549 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4551 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4553 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4555 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4557 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4560 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4561 Indent some of them to GNU standards.
4563 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4564 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4565 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4566 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4567 Update copyright years.
4569 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4571 * som.c (som_prep_for_fixups): A relocation involving the section
4572 symbol for the *ABS* section is really a relocation involving
4574 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4575 undefined symbols. Correctly distinguish between debugger symbols
4576 and section symbols.
4578 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4579 for spaces and subspaces.
4581 * som.c (som_bfd_count_ar_symbols): Fix typo.
4583 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4584 HAS_RELOC based on the object's magic number.
4585 (make_unique_section): Delete function. BFD and its users are
4586 prepared to handle multiple sections with the same name.
4587 (setup_sections): Allocate space on the BFD's obstack to hold
4588 section names. Use bfd_make_setion_anyway rather than the
4589 obsolete make_unique_section.
4590 (som_prep_headers): Choose the correct SOM magic number based
4592 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4594 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4596 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4597 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4598 * Makefile.in, configure.in: Corresponding changes.
4600 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4602 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
4604 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4606 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4607 is always located at the start of the data section to allow
4608 recovery of the dynamic info from a stripped executable.
4609 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4612 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4614 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4615 cruft (like the #pragma alloca for AIX).
4616 In addition to that problem, the C alloca calls xmalloc, which
4617 means checking for being out of memory can't work right. The
4618 following changes remove all uses of alloca from BFD.
4619 * hosts/solaris2.h: Remove alloca cruft.
4620 * som.c: Replace alloca with a fixed size auto array.
4621 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4622 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4623 sunos.c: Replace alloca with malloc and appropriate error checking and
4625 * linker.c: Replace alloca with obstack_alloc.
4626 * libbfd.h: Rebuilt.
4628 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4630 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4633 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4635 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4636 Elf*_Off typedefs by their expansion, the typedefs have been
4637 removed from include/elf/internal.h.
4638 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4639 SHT_PROGBITS section.
4641 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4643 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4647 * configure.host: Recognize i[34]86-sequent-*.
4649 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4650 return from bfd_seek indicates an error.
4651 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4652 TRAD_CORE_STACK_OFFSET.
4653 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4654 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4656 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4658 * som.[ch]: Do not include libhppa.h in som.c, instead include
4661 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4662 include it in elf32-hppa.h.
4664 * som.c (log2): Return -1 on error rather than aborting.
4665 (setup_sections): Bubble up an error from log2.
4667 * Changes to make HP C compiler happy in both traditional
4669 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4671 (bfd_som_set_section_attributes): Use unsigned int rather than
4672 unsigned char to avoid GNU-C extensions.
4673 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4674 or failure rather than aborting on failure.
4676 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4678 (bfd_som_attach_aux_hdr): Add prototype.
4679 (hppa_som-gen_reloc_type): Likewise.
4681 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4682 (hppa_look_for_stubs_in_section): Do not return false on failure
4683 until rest of code is ready to handle it. Abort for now.

4687 * bfd-in2.h: Rebuilt.
4689 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

4698 * config/i386-os9k.mt : Newly add os9k target makefile.
4700 * i386os9k.c : new file to handle os9k format bfd.
4701 * Makefile.in : Handle new file i386os9k.c
4702 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
4703 * cache.c : Initialize cache_sentinel to 0.

4707 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
4708 action in case where caller specified no argument relocation.
4709 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4710 right in the original relocation and the stub's relocation.
4712 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4713 unused symbols argument.
4715 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4716 than asymbol * for original target symbol. All callers changed.
4717 Set reloc->sym_ptr_ptr appropriately.
4718 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4719 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4720 argument. Use the output symbols when canonicalizing the relocs,
4721 creating them if necessary.
4723 * linker.c (_bfd_generic_link_output_symbols): Do not
4724 rebuild/clobber the output symbols if they already exist.
4726 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4728 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4729 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4730 * bfd-in2.h: Rebuilt.
4732 * srec.c (hex_value): Always set to a size of 256 bytes.
4733 (srec_init): Cosmetic changes.
4735 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4737 * elf32-hppa.c: Second half of major cleanup. More comments,
4738 PARAMize and staticize rest of functions. Delete unused
4739 functions. Delete unused/unnecessary arguments to some functions.
4740 Group static vars together. Abort for bad errors until we have
4741 error code propogation working. Work on spacing and indention.
4742 Add FIXMEs for unresolved problems. Use enums rather than
4743 #defines for lots of things. Merge two functions which build
4744 linker stubs into a single function (so they can easily share a
4745 ton of common code).
4747 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4749 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4750 avoid depending upon right shifts of signed numbers, and to
4751 correct handling of src_mask with lower bits zero.
4753 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
4754 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

4779 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
4781 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.

5673 The sparc (and possibly other?) NLM format requires a different
5674 way to write exports, so add a write_export field to the backend
5675 data (and set it to NULL for everything but the sparc).

5908 * nlmcode.h (nlm_object_p): If we can't read the fixed header,
