4327 allocating space for relocations. Handle them in link_order loop.
4328 (_bfd_generic_reloc_link_order): New function.
4329 (_bfd_default_link_order): If a reloc_link_order is seen here,
4331 (_bfd_count_link_order_relocs): New function.
4332 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
4333 argument from declaration.
4334 (_bfd_generic_reloc_link_order): Declare.
4335 (_bfd_count_link_order_relocs): Declare.
4336 * libbfd.h: Rebuilt.
4337 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
4338 call to _bfd_generic_link_add_one_symbol.
4339 (NAME(aout,final_link)): Account for link_order relocs when
4340 allocating space for relocations. Handle them after handling all
4342 (aout_link_reloc_link_order): New function.
4343 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
4344 call to _bfd_generic_link_add_one_symbol.
4345 (ecoff_bfd_final_link): Account for link_order relocs when
4346 allocating space for relocations. Handle them in link_order loop.
4347 (ecoff_link_write_external): Set the storage class of a defined
4348 linker created symbol based on the section it is in. Correct
4349 bfd_link_hash_weak case to use .sc rather than .st.
4350 (ecoff_reloc_link_order): New function.
4351 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4353 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
4355 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
4358 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4359 bfd_zmalloc. Free a pointer, not a union.
4360 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4362 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4364 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4366 * som.c (bfd_section_from_som_symbol): Only to do the value
4367 comparison for function symbols within executables.
4369 * som.c (bfd_section_from_som_symbol): Renamed from
4370 som_section_from_subspace_index. Pass in a native SOM symbol.
4371 For executables, iterate through the sections to find out
4372 which contains the symbol's address rather than using the
4373 symbol_info field. (symbol_info has a different meaning for
4374 dynamicly linked executables.)
4376 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4379 * som.c (som_begin_writing): Fix braino (one call to align
4380 space/subspace data was done unconditionally rather than
4381 just for executables.)
4383 * som.c (som_begin_writing): Align text in all executables to
4384 make HPUX kernel happy. Fixes strip/objcopy for shared
4387 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4389 * som.c (som_begin_writing): Account for alignment needs of
4390 subspaces too when writing executables. Never request a negative
4391 bss size. Fixes some problems with demand paged executables,
4392 still having problems with pure executables and shared executables.
4394 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4396 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4397 bfd_zalloc for rawptr, because later on we may call free, not
4400 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4401 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4402 * cisco-core.c: New file.
4403 * Makefile.in: Change accordingly.
4404 * configure.in: Recognize cisco_core_vec.
4405 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4406 * targets.c: Add cisco_core_vec.
4407 * bfd-in2.h: Rebuilt.
4409 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4411 * som.h (som_copyable_section_data_struct): New structure
4412 containing all the private section information which needs
4413 to be copied from input section to output section during
4415 (som_section_data_struct): Remove several fields now in
4416 som_copyable_section_data_struct. Make the space and
4417 subspace dictionaries be pointers (to save space when
4418 only reading objects).
4420 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4421 some references changed. Allocate a copyable data stucture if
4422 none exists. Store info into the copyable data structure.
4423 (bfd_som_set_subsection_attributes): Likewise.
4424 (som_is_space, som_is_subspace, som_is_container): New functions.
4425 Use these instead of directly accessing private data.
4426 (som_prep_headers): Allocate space and subspace headers here.
4427 Fill in some fields in the space/subspace headers from the
4429 (som_bfd_copy_private_section_data): Only copy the stuff
4430 that we really need to make objcopy and strip work. Allocate
4431 the copy_data structure for the output bfd before copying.
4433 * som.h (struct som_exec_data): New structure to hold exec
4434 info that must be preserved when running objcopy/strip.
4435 (struct somdata): Add new "exec_data" field and accessor
4436 macro. Add some comments on how the various fields are used.
4437 (som_section_data_struct): Make is_space and is_subspace bitfields.
4438 Delete unused subspace_index. All references now use the
4439 target_index field within the section structure itself.
4441 * som.c (make_unique_section): Delete unused declaration.
4442 (som_bfd_copy_private_bfd_data): New function.
4443 (som_object_setup): Allocate space for and save exec information
4444 that needs to be copied during objcopy/strip.
4445 (som_mkobject): Do not allocate space for a file header here.
4446 It is not used when only reading SOM objects.
4447 (som_prep_headers): Allocate space for and attach a file header
4448 to the output bfd. For executables, use the saved system_id
4449 value rather than trying to guess the right value. Do not abort
4450 wwhen setting file_hdr->entry* for executables.
4451 (som_begin_writing): For executables, set the exec_entry and
4453 (som_copy_private_backend_section_data): Always return a value.
4455 * libhppa.h (PA_PAGESIZE): Define.
4457 * som.c (SOM_ALIGN): Define.
4458 (som_begin_writing): If writing an executable, initialize all
4459 fields in the exec header to zero. Update fields in the exec
4460 header as sizes of loadable subspaces are computed. Carefully
4461 preserve alignments when building executables. Actually write the
4462 exec after all the fields are filled in.
4464 * Better long-filename handling. Reads SOM ABI compliant extended
4465 names, but doesn't quite write compliant extended names yet.
4466 * som.c (som_slurp_extended_name_table): Delete function. The
4467 generic code will handle things correctly.
4468 (som_slurp_armap): Seek to the beginning of the next member.
4469 (normalize): New function.
4470 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4471 name table into account when computing the file offsets in the
4472 SOM dictionary. Make sure to align to an even boundary.
4473 (som_write_armap): Initialize the checksum to zero.
4474 (ar_maxchars): Fix. Opps.
4476 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4478 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4479 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4481 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4483 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4484 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4485 * bfd-in2.h: Regenerated.
4487 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4488 this was also named trad_unix_bfd_copy_private_bfd_data.
4490 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4492 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4493 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4494 returns NULL, it is not an error. It's possible that some of
4495 these checks are not necessary (because the size can never be
4496 zero), but putting in the checks is the conservative thing to do
4497 in light of the fact that some of these malloc calls replaced
4498 unchecked alloca calls, in which a zero argument would work fine.
4500 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4502 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4503 duplicate definition.
4504 (osf_core_bfd_is_local_label): Define.
4506 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4507 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4508 failure indication, it merely means there are no relocs.
4510 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4511 after NAME, since SunOS /bin/cc can't handle it.
4513 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4515 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4516 From sukes@glue.umd.edu (Tasuki Hirata).
4518 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4520 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4521 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4522 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4524 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4526 * som.c (som_prep_for_fixups): Detect section symbols based
4527 on either the lack of private data or the symbol flags. Do not
4528 munge section symbol names anymore -- they no longer confuse GDB.
4529 (som_begin_writing): Leave space for an exec header if writing
4531 (som_slurp_symbol_table): Recognize both forms of section symbol
4532 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4533 section symbols to be the name of the section they represent.
4534 Debugging symbols begin with "L$0\001", not just "L$".
4536 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4538 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4540 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4541 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4542 and bfd_is_local_label.
4544 * targets.c: Add new entries to the bfd_target structure.
4546 * bfd.c (bfd_copy_private_bfd_data): New definition.
4548 * section.c (bfd_copy_private_section_data): New definition.
4550 * syms.c (bfd_is_local_label): New definition.
4552 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4554 * libbfd.c (bfd_generic_is_local_label): New function.
4556 * *-core.c: Provide default definitions for new functions in
4557 the target vector which all point to bfd_false.
4559 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4560 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4561 Default new vectors for copying private backend data to bfd_true.
4562 Default new vector for determining if a symbol is a local label
4563 to bfd_generic_is_local_label.
4565 * som.c (som_bfd_copy_private_section_data): New function.
4566 (som_bfd_is_local_label): New function.
4567 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4569 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4571 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4573 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4575 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4578 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4579 Indent some of them to GNU standards.
4581 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4582 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4583 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4584 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4585 Update copyright years.
4587 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4589 * som.c (som_prep_for_fixups): A relocation involving the section
4590 symbol for the *ABS* section is really a relocation involving
4592 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4593 undefined symbols. Correctly distinguish between debugger symbols
4594 and section symbols.
4596 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4597 for spaces and subspaces.
4599 * som.c (som_bfd_count_ar_symbols): Fix typo.
4601 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4602 HAS_RELOC based on the object's magic number.
4603 (make_unique_section): Delete function. BFD and its users are
4604 prepared to handle multiple sections with the same name.
4605 (setup_sections): Allocate space on the BFD's obstack to hold
4606 section names. Use bfd_make_setion_anyway rather than the
4607 obsolete make_unique_section.
4608 (som_prep_headers): Choose the correct SOM magic number based
4610 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4612 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4614 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4615 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4616 * Makefile.in, configure.in: Corresponding changes.
4618 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4620 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
4622 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4624 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4625 is always located at the start of the data section to allow
4626 recovery of the dynamic info from a stripped executable.
4627 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4630 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4632 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4633 cruft (like the #pragma alloca for AIX).
4634 In addition to that problem, the C alloca calls xmalloc, which
4635 means checking for being out of memory can't work right. The
4636 following changes remove all uses of alloca from BFD.
4637 * hosts/solaris2.h: Remove alloca cruft.
4638 * som.c: Replace alloca with a fixed size auto array.
4639 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4640 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4641 sunos.c: Replace alloca with malloc and appropriate error checking and
4643 * linker.c: Replace alloca with obstack_alloc.
4644 * libbfd.h: Rebuilt.
4646 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4648 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4651 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4653 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4654 Elf*_Off typedefs by their expansion, the typedefs have been
4655 removed from include/elf/internal.h.
4656 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4657 SHT_PROGBITS section.
4659 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4661 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4665 * configure.host: Recognize i[34]86-sequent-*.
4667 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4668 return from bfd_seek indicates an error.
4669 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4670 TRAD_CORE_STACK_OFFSET.
4671 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4672 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4674 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4676 * som.[ch]: Do not include libhppa.h in som.c, instead include
4679 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4680 include it in elf32-hppa.h.
4682 * som.c (log2): Return -1 on error rather than aborting.
4683 (setup_sections): Bubble up an error from log2.
4685 * Changes to make HP C compiler happy in both traditional
4687 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4689 (bfd_som_set_section_attributes): Use unsigned int rather than
4690 unsigned char to avoid GNU-C extensions.
4691 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4692 or failure rather than aborting on failure.
4694 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4696 (bfd_som_attach_aux_hdr): Add prototype.
4697 (hppa_som-gen_reloc_type): Likewise.
4699 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4700 (hppa_look_for_stubs_in_section): Do not return false on failure
4701 until rest of code is ready to handle it. Abort for now.
4703 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4705 * bfd-in2.h: Rebuilt.
4707 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

4716 * config/i386-os9k.mt : Newly add os9k target makefile.
4718 * i386os9k.c : new file to handle os9k format bfd.
4719 * Makefile.in : Handle new file i386os9k.c
4720 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
4721 * cache.c : Initialize cache_sentinel to 0.

4725 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
4726 action in case where caller specified no argument relocation.
4727 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4728 right in the original relocation and the stub's relocation.
4730 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4731 unused symbols argument.
4733 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4734 than asymbol * for original target symbol. All callers changed.
4735 Set reloc->sym_ptr_ptr appropriately.
4736 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4737 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4738 argument. Use the output symbols when canonicalizing the relocs,
4739 creating them if necessary.
4741 * linker.c (_bfd_generic_link_output_symbols): Do not
4742 rebuild/clobber the output symbols if they already exist.
4744 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4746 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4747 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4748 * bfd-in2.h: Rebuilt.
4750 * srec.c (hex_value): Always set to a size of 256 bytes.
4751 (srec_init): Cosmetic changes.
4753 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4755 * elf32-hppa.c: Second half of major cleanup. More comments,
4756 PARAMize and staticize rest of functions. Delete unused
4757 functions. Delete unused/unnecessary arguments to some functions.
4758 Group static vars together. Abort for bad errors until we have
4759 error code propogation working. Work on spacing and indention.
4760 Add FIXMEs for unresolved problems. Use enums rather than
4761 #defines for lots of things. Merge two functions which build
4762 linker stubs into a single function (so they can easily share a
4763 ton of common code).
4765 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4767 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4768 avoid depending upon right shifts of signed numbers, and to
4769 correct handling of src_mask with lower bits zero.
4771 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
4772 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
4773 * elf32-i386.c: Likewise.
4774 * elfcode.h (bfd_section_from_shdr): Make i unsigned; remove old

6977 terms of MY, because that causes a recusive invocation of CAT when
6978 expanded within JUMP_TABLE, and ANSI compilers don't expand
6980 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
6981 MY_reloc_howto_type_lookup, and don't define in terms of MY.
6982 (MY_canonicalize_reloc): Don't define in terms of MY.
6983 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
6984 than listing functions.
