4321 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4323 * som.c (bfd_section_from_som_symbol): Only to do the value
4324 comparison for function symbols within executables.
4326 * som.c (bfd_section_from_som_symbol): Renamed from
4327 som_section_from_subspace_index. Pass in a native SOM symbol.
4328 For executables, iterate through the sections to find out
4329 which contains the symbol's address rather than using the
4330 symbol_info field. (symbol_info has a different meaning for
4331 dynamicly linked executables.)
4333 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4336 * som.c (som_begin_writing): Fix braino (one call to align
4337 space/subspace data was done unconditionally rather than
4338 just for executables.)
4340 * som.c (som_begin_writing): Align text in all executables to
4341 make HPUX kernel happy. Fixes strip/objcopy for shared
4344 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4346 * som.c (som_begin_writing): Account for alignment needs of
4347 subspaces too when writing executables. Never request a negative
4348 bss size. Fixes some problems with demand paged executables,
4349 still having problems with pure executables and shared executables.
4351 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4353 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4354 bfd_zalloc for rawptr, because later on we may call free, not
4357 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4358 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4359 * cisco-core.c: New file.
4360 * Makefile.in: Change accordingly.
4361 * configure.in: Recognize cisco_core_vec.
4362 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4363 * targets.c: Add cisco_core_vec.
4364 * bfd-in2.h: Rebuilt.
4366 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4368 * som.h (som_copyable_section_data_struct): New structure
4369 containing all the private section information which needs
4370 to be copied from input section to output section during
4372 (som_section_data_struct): Remove several fields now in
4373 som_copyable_section_data_struct. Make the space and
4374 subspace dictionaries be pointers (to save space when
4375 only reading objects).
4377 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4378 some references changed. Allocate a copyable data stucture if
4379 none exists. Store info into the copyable data structure.
4380 (bfd_som_set_subsection_attributes): Likewise.
4381 (som_is_space, som_is_subspace, som_is_container): New functions.
4382 Use these instead of directly accessing private data.
4383 (som_prep_headers): Allocate space and subspace headers here.
4384 Fill in some fields in the space/subspace headers from the
4386 (som_bfd_copy_private_section_data): Only copy the stuff
4387 that we really need to make objcopy and strip work. Allocate
4388 the copy_data structure for the output bfd before copying.
4390 * som.h (struct som_exec_data): New structure to hold exec
4391 info that must be preserved when running objcopy/strip.
4392 (struct somdata): Add new "exec_data" field and accessor
4393 macro. Add some comments on how the various fields are used.
4394 (som_section_data_struct): Make is_space and is_subspace bitfields.
4395 Delete unused subspace_index. All references now use the
4396 target_index field within the section structure itself.
4398 * som.c (make_unique_section): Delete unused declaration.
4399 (som_bfd_copy_private_bfd_data): New function.
4400 (som_object_setup): Allocate space for and save exec information
4401 that needs to be copied during objcopy/strip.
4402 (som_mkobject): Do not allocate space for a file header here.
4403 It is not used when only reading SOM objects.
4404 (som_prep_headers): Allocate space for and attach a file header
4405 to the output bfd. For executables, use the saved system_id
4406 value rather than trying to guess the right value. Do not abort
4407 wwhen setting file_hdr->entry* for executables.
4408 (som_begin_writing): For executables, set the exec_entry and
4410 (som_copy_private_backend_section_data): Always return a value.
4412 * libhppa.h (PA_PAGESIZE): Define.
4414 * som.c (SOM_ALIGN): Define.
4415 (som_begin_writing): If writing an executable, initialize all
4416 fields in the exec header to zero. Update fields in the exec
4417 header as sizes of loadable subspaces are computed. Carefully
4418 preserve alignments when building executables. Actually write the
4419 exec after all the fields are filled in.
4421 * Better long-filename handling. Reads SOM ABI compliant extended
4422 names, but doesn't quite write compliant extended names yet.
4423 * som.c (som_slurp_extended_name_table): Delete function. The
4424 generic code will handle things correctly.
4425 (som_slurp_armap): Seek to the beginning of the next member.
4426 (normalize): New function.
4427 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4428 name table into account when computing the file offsets in the
4429 SOM dictionary. Make sure to align to an even boundary.
4430 (som_write_armap): Initialize the checksum to zero.
4431 (ar_maxchars): Fix. Opps.
4433 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4435 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4436 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4438 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4440 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4441 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4442 * bfd-in2.h: Regenerated.
4444 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4445 this was also named trad_unix_bfd_copy_private_bfd_data.
4447 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4449 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4450 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4451 returns NULL, it is not an error. It's possible that some of
4452 these checks are not necessary (because the size can never be
4453 zero), but putting in the checks is the conservative thing to do
4454 in light of the fact that some of these malloc calls replaced
4455 unchecked alloca calls, in which a zero argument would work fine.
4457 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4459 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4460 duplicate definition.
4461 (osf_core_bfd_is_local_label): Define.
4463 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4464 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4465 failure indication, it merely means there are no relocs.
4467 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4468 after NAME, since SunOS /bin/cc can't handle it.
4470 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4472 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4473 From sukes@glue.umd.edu (Tasuki Hirata).
4475 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4477 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4478 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4479 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4481 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4483 * som.c (som_prep_for_fixups): Detect section symbols based
4484 on either the lack of private data or the symbol flags. Do not
4485 munge section symbol names anymore -- they no longer confuse GDB.
4486 (som_begin_writing): Leave space for an exec header if writing
4488 (som_slurp_symbol_table): Recognize both forms of section symbol
4489 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4490 section symbols to be the name of the section they represent.
4491 Debugging symbols begin with "L$0\001", not just "L$".
4493 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4495 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4497 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4498 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4499 and bfd_is_local_label.
4501 * targets.c: Add new entries to the bfd_target structure.
4503 * bfd.c (bfd_copy_private_bfd_data): New definition.
4505 * section.c (bfd_copy_private_section_data): New definition.
4507 * syms.c (bfd_is_local_label): New definition.
4509 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4511 * libbfd.c (bfd_generic_is_local_label): New function.
4513 * *-core.c: Provide default definitions for new functions in
4514 the target vector which all point to bfd_false.
4516 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4517 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4518 Default new vectors for copying private backend data to bfd_true.
4519 Default new vector for determining if a symbol is a local label
4520 to bfd_generic_is_local_label.
4522 * som.c (som_bfd_copy_private_section_data): New function.
4523 (som_bfd_is_local_label): New function.
4524 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4526 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4528 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4530 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4532 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4535 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4536 Indent some of them to GNU standards.
4538 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4539 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4540 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4541 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4542 Update copyright years.
4544 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4546 * som.c (som_prep_for_fixups): A relocation involving the section
4547 symbol for the *ABS* section is really a relocation involving
4549 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4550 undefined symbols. Correctly distinguish between debugger symbols
4551 and section symbols.
4553 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4554 for spaces and subspaces.
4556 * som.c (som_bfd_count_ar_symbols): Fix typo.
4558 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4559 HAS_RELOC based on the object's magic number.
4560 (make_unique_section): Delete function. BFD and its users are
4561 prepared to handle multiple sections with the same name.
4562 (setup_sections): Allocate space on the BFD's obstack to hold
4563 section names. Use bfd_make_setion_anyway rather than the
4564 obsolete make_unique_section.
4565 (som_prep_headers): Choose the correct SOM magic number based
4567 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4569 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4571 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4572 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4573 * Makefile.in, configure.in: Corresponding changes.
4575 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4577 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
4579 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4581 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4582 is always located at the start of the data section to allow
4583 recovery of the dynamic info from a stripped executable.
4584 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4587 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4589 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4590 cruft (like the #pragma alloca for AIX).
4591 In addition to that problem, the C alloca calls xmalloc, which
4592 means checking for being out of memory can't work right. The
4593 following changes remove all uses of alloca from BFD.
4594 * hosts/solaris2.h: Remove alloca cruft.
4595 * som.c: Replace alloca with a fixed size auto array.
4596 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4597 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4598 sunos.c: Replace alloca with malloc and appropriate error checking and
4600 * linker.c: Replace alloca with obstack_alloc.
4601 * libbfd.h: Rebuilt.
4603 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4605 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4608 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4610 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4611 Elf*_Off typedefs by their expansion, the typedefs have been
4612 removed from include/elf/internal.h.
4613 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4614 SHT_PROGBITS section.
4616 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4618 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4622 * configure.host: Recognize i[34]86-sequent-*.
4624 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4625 return from bfd_seek indicates an error.
4626 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4627 TRAD_CORE_STACK_OFFSET.
4628 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4629 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4631 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4633 * som.[ch]: Do not include libhppa.h in som.c, instead include
4636 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4637 include it in elf32-hppa.h.
4639 * som.c (log2): Return -1 on error rather than aborting.
4640 (setup_sections): Bubble up an error from log2.
4642 * Changes to make HP C compiler happy in both traditional
4644 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4646 (bfd_som_set_section_attributes): Use unsigned int rather than
4647 unsigned char to avoid GNU-C extensions.
4648 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4649 or failure rather than aborting on failure.
4651 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4653 (bfd_som_attach_aux_hdr): Add prototype.
4654 (hppa_som-gen_reloc_type): Likewise.
4656 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4657 (hppa_look_for_stubs_in_section): Do not return false on failure
4658 until rest of code is ready to handle it. Abort for now.
4660 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4662 * bfd-in2.h: Rebuilt.
4664 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
4666 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

4670 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
4672 * config.bfd : Add i386-os9k.
4673 * config/i386-os9k.mt : Newly add os9k target makefile.
4675 * i386os9k.c : new file to handle os9k format bfd.
4676 * Makefile.in : Handle new file i386os9k.c
4677 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
4678 * cache.c : Initialize cache_sentinel to 0.

4682 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
4683 action in case where caller specified no argument relocation.
4684 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4685 right in the original relocation and the stub's relocation.
4687 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4688 unused symbols argument.
4690 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4691 than asymbol * for original target symbol. All callers changed.
4692 Set reloc->sym_ptr_ptr appropriately.
4693 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4694 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4695 argument. Use the output symbols when canonicalizing the relocs,
4696 creating them if necessary.
4698 * linker.c (_bfd_generic_link_output_symbols): Do not
4699 rebuild/clobber the output symbols if they already exist.
4701 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4703 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4704 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4705 * bfd-in2.h: Rebuilt.
4707 * srec.c (hex_value): Always set to a size of 256 bytes.
4708 (srec_init): Cosmetic changes.
4710 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4712 * elf32-hppa.c: Second half of major cleanup. More comments,
4713 PARAMize and staticize rest of functions. Delete unused
4714 functions. Delete unused/unnecessary arguments to some functions.
4715 Group static vars together. Abort for bad errors until we have
4716 error code propogation working. Work on spacing and indention.
4717 Add FIXMEs for unresolved problems. Use enums rather than
4718 #defines for lots of things. Merge two functions which build
4719 linker stubs into a single function (so they can easily share a
4720 ton of common code).
4722 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4724 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4725 avoid depending upon right shifts of signed numbers, and to
4726 correct handling of src_mask with lower bits zero.
4728 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
4729 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
4730 * elf32-i386.c: Likewise.

4735 (assign_file_positions_except_relocs): Make i unsigned.
4736 (write_shdrs_and_ehdr): Make count unsigned.
4737 (assign_file_positions_for_relocs): Make i unsigned.
4738 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
4739 (section_from_elf_index): Make index argument unsigned.
4741 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
4743 * elfcode.h: Don't include assert.h.
4744 (swap_out_syms): Use BFD_ASSERT rather than assert.
4746 * linker.c (_bfd_generic_link_write_global_symbol): Add missing
4749 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
4752 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4754 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
4756 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
4757 (elf_hppa_tc_make_sections): Likewise.
4758 (elf_hppa_final_processing): Add extern decl.
4760 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4761 comments. PARAMize some static functions. Delete unused functions.
4762 Delete unused/unnecessary arguments to many functions. Group
4763 static vars together. Collapse common case statements together
4764 in many places. Use default case when possible instead of listing
4765 each case separately. Abort for bad errors until we get error
4766 code propogation working. Work on spacing and indention problems.
4767 Add FIXMEs for some unresolved problems. Delete hopelessly broken
4768 COMPLEX relocation support (it's never used anyway).
4769 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4770 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4771 (elf_hppa_tc_make_sections): Likewise.
4773 * format.c (bfd_check_format_matches): Initialize matching_vector
4774 to keep gcc -Wall quiet.

5510 bfd_som_set_subsection_attributes): Change parameters from char
5511 to int. Following a prototype with an old-style function definition

5618 use get_value to get the symbol value and check for undefined
5620 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5621 undefined, look it up in the linker hash table.
5623 * aoutx.h (translate_symbol_table): The string index 0 has a

5648 The sparc (and possibly other?) NLM format requires a different
5649 way to write exports, so add a write_export field to the backend
5650 data (and set it to NULL for everything but the sparc).
