4317 bfd_link_hash_weak case to use .sc rather than .st.
4318 (ecoff_reloc_link_order): New function.
4319 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4321 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
4323 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
4326 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4327 bfd_zmalloc. Free a pointer, not a union.
4328 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4330 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4332 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4334 * som.c (bfd_section_from_som_symbol): Only to do the value
4335 comparison for function symbols within executables.
4337 * som.c (bfd_section_from_som_symbol): Renamed from
4338 som_section_from_subspace_index. Pass in a native SOM symbol.
4339 For executables, iterate through the sections to find out
4340 which contains the symbol's address rather than using the
4341 symbol_info field. (symbol_info has a different meaning for
4342 dynamicly linked executables.)
4344 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4347 * som.c (som_begin_writing): Fix braino (one call to align
4348 space/subspace data was done unconditionally rather than
4349 just for executables.)
4351 * som.c (som_begin_writing): Align text in all executables to
4352 make HPUX kernel happy. Fixes strip/objcopy for shared
4355 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4357 * som.c (som_begin_writing): Account for alignment needs of
4358 subspaces too when writing executables. Never request a negative
4359 bss size. Fixes some problems with demand paged executables,
4360 still having problems with pure executables and shared executables.
4362 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4364 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4365 bfd_zalloc for rawptr, because later on we may call free, not
4368 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4369 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4370 * cisco-core.c: New file.
4371 * Makefile.in: Change accordingly.
4372 * configure.in: Recognize cisco_core_vec.
4373 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4374 * targets.c: Add cisco_core_vec.
4375 * bfd-in2.h: Rebuilt.
4377 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4379 * som.h (som_copyable_section_data_struct): New structure
4380 containing all the private section information which needs
4381 to be copied from input section to output section during
4383 (som_section_data_struct): Remove several fields now in
4384 som_copyable_section_data_struct. Make the space and
4385 subspace dictionaries be pointers (to save space when
4386 only reading objects).
4388 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4389 some references changed. Allocate a copyable data stucture if
4390 none exists. Store info into the copyable data structure.
4391 (bfd_som_set_subsection_attributes): Likewise.
4392 (som_is_space, som_is_subspace, som_is_container): New functions.
4393 Use these instead of directly accessing private data.
4394 (som_prep_headers): Allocate space and subspace headers here.
4395 Fill in some fields in the space/subspace headers from the
4397 (som_bfd_copy_private_section_data): Only copy the stuff
4398 that we really need to make objcopy and strip work. Allocate
4399 the copy_data structure for the output bfd before copying.
4401 * som.h (struct som_exec_data): New structure to hold exec
4402 info that must be preserved when running objcopy/strip.
4403 (struct somdata): Add new "exec_data" field and accessor
4404 macro. Add some comments on how the various fields are used.
4405 (som_section_data_struct): Make is_space and is_subspace bitfields.
4406 Delete unused subspace_index. All references now use the
4407 target_index field within the section structure itself.
4409 * som.c (make_unique_section): Delete unused declaration.
4410 (som_bfd_copy_private_bfd_data): New function.
4411 (som_object_setup): Allocate space for and save exec information
4412 that needs to be copied during objcopy/strip.
4413 (som_mkobject): Do not allocate space for a file header here.
4414 It is not used when only reading SOM objects.
4415 (som_prep_headers): Allocate space for and attach a file header
4416 to the output bfd. For executables, use the saved system_id
4417 value rather than trying to guess the right value. Do not abort
4418 wwhen setting file_hdr->entry* for executables.
4419 (som_begin_writing): For executables, set the exec_entry and
4421 (som_copy_private_backend_section_data): Always return a value.
4423 * libhppa.h (PA_PAGESIZE): Define.
4425 * som.c (SOM_ALIGN): Define.
4426 (som_begin_writing): If writing an executable, initialize all
4427 fields in the exec header to zero. Update fields in the exec
4428 header as sizes of loadable subspaces are computed. Carefully
4429 preserve alignments when building executables. Actually write the
4430 exec after all the fields are filled in.
4432 * Better long-filename handling. Reads SOM ABI compliant extended
4433 names, but doesn't quite write compliant extended names yet.
4434 * som.c (som_slurp_extended_name_table): Delete function. The
4435 generic code will handle things correctly.
4436 (som_slurp_armap): Seek to the beginning of the next member.
4437 (normalize): New function.
4438 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4439 name table into account when computing the file offsets in the
4440 SOM dictionary. Make sure to align to an even boundary.
4441 (som_write_armap): Initialize the checksum to zero.
4442 (ar_maxchars): Fix. Opps.
4444 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4446 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4447 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4449 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4451 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4452 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4453 * bfd-in2.h: Regenerated.
4455 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4456 this was also named trad_unix_bfd_copy_private_bfd_data.
4458 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4460 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4461 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4462 returns NULL, it is not an error. It's possible that some of
4463 these checks are not necessary (because the size can never be
4464 zero), but putting in the checks is the conservative thing to do
4465 in light of the fact that some of these malloc calls replaced
4466 unchecked alloca calls, in which a zero argument would work fine.
4468 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4470 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4471 duplicate definition.
4472 (osf_core_bfd_is_local_label): Define.
4474 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4475 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4476 failure indication, it merely means there are no relocs.
4478 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4479 after NAME, since SunOS /bin/cc can't handle it.
4481 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4483 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4484 From sukes@glue.umd.edu (Tasuki Hirata).
4486 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4488 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4489 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4490 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4492 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4494 * som.c (som_prep_for_fixups): Detect section symbols based
4495 on either the lack of private data or the symbol flags. Do not
4496 munge section symbol names anymore -- they no longer confuse GDB.
4497 (som_begin_writing): Leave space for an exec header if writing
4499 (som_slurp_symbol_table): Recognize both forms of section symbol
4500 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4501 section symbols to be the name of the section they represent.
4502 Debugging symbols begin with "L$0\001", not just "L$".
4504 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4506 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4508 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4509 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4510 and bfd_is_local_label.
4512 * targets.c: Add new entries to the bfd_target structure.
4514 * bfd.c (bfd_copy_private_bfd_data): New definition.
4516 * section.c (bfd_copy_private_section_data): New definition.
4518 * syms.c (bfd_is_local_label): New definition.
4520 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4522 * libbfd.c (bfd_generic_is_local_label): New function.
4524 * *-core.c: Provide default definitions for new functions in
4525 the target vector which all point to bfd_false.
4527 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4528 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4529 Default new vectors for copying private backend data to bfd_true.
4530 Default new vector for determining if a symbol is a local label
4531 to bfd_generic_is_local_label.
4533 * som.c (som_bfd_copy_private_section_data): New function.
4534 (som_bfd_is_local_label): New function.
4535 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4537 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4539 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4541 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4543 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4546 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4547 Indent some of them to GNU standards.
4549 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4550 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4551 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4552 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4553 Update copyright years.
4555 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4557 * som.c (som_prep_for_fixups): A relocation involving the section
4558 symbol for the *ABS* section is really a relocation involving
4560 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4561 undefined symbols. Correctly distinguish between debugger symbols
4562 and section symbols.
4564 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4565 for spaces and subspaces.
4567 * som.c (som_bfd_count_ar_symbols): Fix typo.
4569 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4570 HAS_RELOC based on the object's magic number.
4571 (make_unique_section): Delete function. BFD and its users are
4572 prepared to handle multiple sections with the same name.
4573 (setup_sections): Allocate space on the BFD's obstack to hold
4574 section names. Use bfd_make_setion_anyway rather than the
4575 obsolete make_unique_section.
4576 (som_prep_headers): Choose the correct SOM magic number based
4578 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4580 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4582 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4583 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4584 * Makefile.in, configure.in: Corresponding changes.
4586 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4588 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
4590 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4592 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4593 is always located at the start of the data section to allow
4594 recovery of the dynamic info from a stripped executable.
4595 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4598 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4600 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4601 cruft (like the #pragma alloca for AIX).
4602 In addition to that problem, the C alloca calls xmalloc, which
4603 means checking for being out of memory can't work right. The
4604 following changes remove all uses of alloca from BFD.
4605 * hosts/solaris2.h: Remove alloca cruft.
4606 * som.c: Replace alloca with a fixed size auto array.
4607 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4608 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4609 sunos.c: Replace alloca with malloc and appropriate error checking and
4611 * linker.c: Replace alloca with obstack_alloc.
4612 * libbfd.h: Rebuilt.
4614 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4616 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4619 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4621 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4622 Elf*_Off typedefs by their expansion, the typedefs have been
4623 removed from include/elf/internal.h.
4624 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4625 SHT_PROGBITS section.
4627 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4629 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4633 * configure.host: Recognize i[34]86-sequent-*.
4635 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4636 return from bfd_seek indicates an error.
4637 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4638 TRAD_CORE_STACK_OFFSET.
4639 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4640 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4642 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4644 * som.[ch]: Do not include libhppa.h in som.c, instead include
4647 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4648 include it in elf32-hppa.h.
4650 * som.c (log2): Return -1 on error rather than aborting.
4651 (setup_sections): Bubble up an error from log2.
4653 * Changes to make HP C compiler happy in both traditional
4655 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4657 (bfd_som_set_section_attributes): Use unsigned int rather than
4658 unsigned char to avoid GNU-C extensions.
4659 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4660 or failure rather than aborting on failure.
4662 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4664 (bfd_som_attach_aux_hdr): Add prototype.
4665 (hppa_som-gen_reloc_type): Likewise.
4667 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4668 (hppa_look_for_stubs_in_section): Do not return false on failure
4669 until rest of code is ready to handle it. Abort for now.

4673 * bfd-in2.h: Rebuilt.
4675 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

4681 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
4683 * config.bfd : Add i386-os9k.
4684 * config/i386-os9k.mt : Newly add os9k target makefile.
4686 * i386os9k.c : new file to handle os9k format bfd.
4687 * Makefile.in : Handle new file i386os9k.c
4688 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
4689 * cache.c : Initialize cache_sentinel to 0.

4693 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
4694 action in case where caller specified no argument relocation.
4695 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4696 right in the original relocation and the stub's relocation.
4698 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4699 unused symbols argument.
4701 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4702 than asymbol * for original target symbol. All callers changed.
4703 Set reloc->sym_ptr_ptr appropriately.
4704 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4705 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4706 argument. Use the output symbols when canonicalizing the relocs,
4707 creating them if necessary.
4709 * linker.c (_bfd_generic_link_output_symbols): Do not
4710 rebuild/clobber the output symbols if they already exist.
4712 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4714 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4715 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4716 * bfd-in2.h: Rebuilt.
4718 * srec.c (hex_value): Always set to a size of 256 bytes.
4719 (srec_init): Cosmetic changes.
4721 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4723 * elf32-hppa.c: Second half of major cleanup. More comments,
4724 PARAMize and staticize rest of functions. Delete unused
4725 functions. Delete unused/unnecessary arguments to some functions.
4726 Group static vars together. Abort for bad errors until we have
4727 error code propogation working. Work on spacing and indention.
4728 Add FIXMEs for unresolved problems. Use enums rather than
4729 #defines for lots of things. Merge two functions which build
4730 linker stubs into a single function (so they can easily share a
4731 ton of common code).
4733 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4735 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4736 avoid depending upon right shifts of signed numbers, and to
4737 correct handling of src_mask with lower bits zero.
4739 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
4740 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

4747 (write_shdrs_and_ehdr): Make count unsigned.
4748 (assign_file_positions_for_relocs): Make i unsigned.
4749 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
4750 (section_from_elf_index): Make index argument unsigned.
4752 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
4754 * elfcode.h: Don't include assert.h.

4760 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
4763 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4765 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
4767 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
4768 (elf_hppa_tc_make_sections): Likewise.
4769 (elf_hppa_final_processing): Add extern decl.
4771 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4772 comments. PARAMize some static functions. Delete unused functions.
4773 Delete unused/unnecessary arguments to many functions. Group
4774 static vars together. Collapse common case statements together
4775 in many places. Use default case when possible instead of listing

4955 bother processing them.

5629 use get_value to get the symbol value and check for undefined
5631 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5632 undefined, look it up in the linker hash table.
5634 * aoutx.h (translate_symbol_table): The string index 0 has a

5659 The sparc (and possibly other?) NLM format requires a different
5660 way to write exports, so add a write_export field to the backend
