4335 * libbfd-in.h (_bfd_generic_link_add_symbols_collect): Declare.
4336 * libbfd.h: Rebuilt.
4338 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4340 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
4341 for first character in an extended name.
4342 (_bfd_write_archive_contents): If ar_padchar == '/', then use
4343 "//" as the name of the special archive member holding the
4344 extended name table.
4346 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4348 Support for link_order types which generate relocs in order to
4349 support -Ur in the linker.
4350 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4351 from call to _bfd_generic_link_add_one_symbol.
4352 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4353 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4354 instead of bitsize to add_to_set call back.
4355 (_bfd_generic_final_link): Account for link_order relocs when
4356 allocating space for relocations. Handle them in link_order loop.
4357 (_bfd_generic_reloc_link_order): New function.
4358 (_bfd_default_link_order): If a reloc_link_order is seen here,
4360 (_bfd_count_link_order_relocs): New function.
4361 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
4362 argument from declaration.
4363 (_bfd_generic_reloc_link_order): Declare.
4364 (_bfd_count_link_order_relocs): Declare.
4365 * libbfd.h: Rebuilt.
4366 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
4367 call to _bfd_generic_link_add_one_symbol.
4368 (NAME(aout,final_link)): Account for link_order relocs when
4369 allocating space for relocations. Handle them after handling all
4371 (aout_link_reloc_link_order): New function.
4372 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
4373 call to _bfd_generic_link_add_one_symbol.
4374 (ecoff_bfd_final_link): Account for link_order relocs when
4375 allocating space for relocations. Handle them in link_order loop.
4376 (ecoff_link_write_external): Set the storage class of a defined
4377 linker created symbol based on the section it is in. Correct
4378 bfd_link_hash_weak case to use .sc rather than .st.
4379 (ecoff_reloc_link_order): New function.
4380 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4382 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
4384 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
4387 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4388 bfd_zmalloc. Free a pointer, not a union.
4389 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4391 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4393 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4395 * som.c (bfd_section_from_som_symbol): Only to do the value
4396 comparison for function symbols within executables.
4398 * som.c (bfd_section_from_som_symbol): Renamed from
4399 som_section_from_subspace_index. Pass in a native SOM symbol.
4400 For executables, iterate through the sections to find out
4401 which contains the symbol's address rather than using the
4402 symbol_info field. (symbol_info has a different meaning for
4403 dynamicly linked executables.)
4405 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4408 * som.c (som_begin_writing): Fix braino (one call to align
4409 space/subspace data was done unconditionally rather than
4410 just for executables.)
4412 * som.c (som_begin_writing): Align text in all executables to
4413 make HPUX kernel happy. Fixes strip/objcopy for shared
4416 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4418 * som.c (som_begin_writing): Account for alignment needs of
4419 subspaces too when writing executables. Never request a negative
4420 bss size. Fixes some problems with demand paged executables,
4421 still having problems with pure executables and shared executables.
4423 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4425 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4426 bfd_zalloc for rawptr, because later on we may call free, not
4429 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4430 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4431 * cisco-core.c: New file.
4432 * Makefile.in: Change accordingly.
4433 * configure.in: Recognize cisco_core_vec.
4434 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4435 * targets.c: Add cisco_core_vec.
4436 * bfd-in2.h: Rebuilt.
4438 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4440 * som.h (som_copyable_section_data_struct): New structure
4441 containing all the private section information which needs
4442 to be copied from input section to output section during
4444 (som_section_data_struct): Remove several fields now in
4445 som_copyable_section_data_struct. Make the space and
4446 subspace dictionaries be pointers (to save space when
4447 only reading objects).
4449 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4450 some references changed. Allocate a copyable data stucture if
4451 none exists. Store info into the copyable data structure.
4452 (bfd_som_set_subsection_attributes): Likewise.
4453 (som_is_space, som_is_subspace, som_is_container): New functions.
4454 Use these instead of directly accessing private data.
4455 (som_prep_headers): Allocate space and subspace headers here.
4456 Fill in some fields in the space/subspace headers from the
4458 (som_bfd_copy_private_section_data): Only copy the stuff
4459 that we really need to make objcopy and strip work. Allocate
4460 the copy_data structure for the output bfd before copying.
4462 * som.h (struct som_exec_data): New structure to hold exec
4463 info that must be preserved when running objcopy/strip.
4464 (struct somdata): Add new "exec_data" field and accessor
4465 macro. Add some comments on how the various fields are used.
4466 (som_section_data_struct): Make is_space and is_subspace bitfields.
4467 Delete unused subspace_index. All references now use the
4468 target_index field within the section structure itself.
4470 * som.c (make_unique_section): Delete unused declaration.
4471 (som_bfd_copy_private_bfd_data): New function.
4472 (som_object_setup): Allocate space for and save exec information
4473 that needs to be copied during objcopy/strip.
4474 (som_mkobject): Do not allocate space for a file header here.
4475 It is not used when only reading SOM objects.
4476 (som_prep_headers): Allocate space for and attach a file header
4477 to the output bfd. For executables, use the saved system_id
4478 value rather than trying to guess the right value. Do not abort
4479 wwhen setting file_hdr->entry* for executables.
4480 (som_begin_writing): For executables, set the exec_entry and
4482 (som_copy_private_backend_section_data): Always return a value.
4484 * libhppa.h (PA_PAGESIZE): Define.
4486 * som.c (SOM_ALIGN): Define.
4487 (som_begin_writing): If writing an executable, initialize all
4488 fields in the exec header to zero. Update fields in the exec
4489 header as sizes of loadable subspaces are computed. Carefully
4490 preserve alignments when building executables. Actually write the
4491 exec after all the fields are filled in.
4493 * Better long-filename handling. Reads SOM ABI compliant extended
4494 names, but doesn't quite write compliant extended names yet.
4495 * som.c (som_slurp_extended_name_table): Delete function. The
4496 generic code will handle things correctly.
4497 (som_slurp_armap): Seek to the beginning of the next member.
4498 (normalize): New function.
4499 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4500 name table into account when computing the file offsets in the
4501 SOM dictionary. Make sure to align to an even boundary.
4502 (som_write_armap): Initialize the checksum to zero.
4503 (ar_maxchars): Fix. Opps.
4505 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4507 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4508 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4510 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4512 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4513 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4514 * bfd-in2.h: Regenerated.
4516 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4517 this was also named trad_unix_bfd_copy_private_bfd_data.
4519 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4521 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4522 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4523 returns NULL, it is not an error. It's possible that some of
4524 these checks are not necessary (because the size can never be
4525 zero), but putting in the checks is the conservative thing to do
4526 in light of the fact that some of these malloc calls replaced
4527 unchecked alloca calls, in which a zero argument would work fine.
4529 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4531 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4532 duplicate definition.
4533 (osf_core_bfd_is_local_label): Define.
4535 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4536 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4537 failure indication, it merely means there are no relocs.
4539 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4540 after NAME, since SunOS /bin/cc can't handle it.
4542 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4544 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4545 From sukes@glue.umd.edu (Tasuki Hirata).
4547 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4549 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4550 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4551 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4553 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4555 * som.c (som_prep_for_fixups): Detect section symbols based
4556 on either the lack of private data or the symbol flags. Do not
4557 munge section symbol names anymore -- they no longer confuse GDB.
4558 (som_begin_writing): Leave space for an exec header if writing
4560 (som_slurp_symbol_table): Recognize both forms of section symbol
4561 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4562 section symbols to be the name of the section they represent.
4563 Debugging symbols begin with "L$0\001", not just "L$".
4565 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4567 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4569 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4570 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4571 and bfd_is_local_label.
4573 * targets.c: Add new entries to the bfd_target structure.
4575 * bfd.c (bfd_copy_private_bfd_data): New definition.
4577 * section.c (bfd_copy_private_section_data): New definition.
4579 * syms.c (bfd_is_local_label): New definition.
4581 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4583 * libbfd.c (bfd_generic_is_local_label): New function.
4585 * *-core.c: Provide default definitions for new functions in
4586 the target vector which all point to bfd_false.
4588 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4589 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4590 Default new vectors for copying private backend data to bfd_true.
4591 Default new vector for determining if a symbol is a local label
4592 to bfd_generic_is_local_label.
4594 * som.c (som_bfd_copy_private_section_data): New function.
4595 (som_bfd_is_local_label): New function.
4596 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4598 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4600 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4602 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4604 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4607 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4608 Indent some of them to GNU standards.
4610 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4611 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4612 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4613 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4614 Update copyright years.
4616 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4618 * som.c (som_prep_for_fixups): A relocation involving the section
4619 symbol for the *ABS* section is really a relocation involving
4621 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4622 undefined symbols. Correctly distinguish between debugger symbols
4623 and section symbols.
4625 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4626 for spaces and subspaces.
4628 * som.c (som_bfd_count_ar_symbols): Fix typo.
4630 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4631 HAS_RELOC based on the object's magic number.
4632 (make_unique_section): Delete function. BFD and its users are
4633 prepared to handle multiple sections with the same name.
4634 (setup_sections): Allocate space on the BFD's obstack to hold
4635 section names. Use bfd_make_setion_anyway rather than the
4636 obsolete make_unique_section.
4637 (som_prep_headers): Choose the correct SOM magic number based
4639 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4641 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4643 * elf32-ppc.c: Renamed from elf32-powerpc.c.

4653 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4654 is always located at the start of the data section to allow
4655 recovery of the dynamic info from a stripped executable.
4656 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4659 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4661 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4662 cruft (like the #pragma alloca for AIX).
4663 In addition to that problem, the C alloca calls xmalloc, which
4664 means checking for being out of memory can't work right. The
4665 following changes remove all uses of alloca from BFD.
4666 * hosts/solaris2.h: Remove alloca cruft.
4667 * som.c: Replace alloca with a fixed size auto array.

4672 * linker.c: Replace alloca with obstack_alloc.
4673 * libbfd.h: Rebuilt.
4675 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4677 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4680 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4682 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4683 Elf*_Off typedefs by their expansion, the typedefs have been
4684 removed from include/elf/internal.h.
4685 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4686 SHT_PROGBITS section.
4688 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4690 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4694 * configure.host: Recognize i[34]86-sequent-*.
4696 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4697 return from bfd_seek indicates an error.
4698 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4699 TRAD_CORE_STACK_OFFSET.
4700 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4701 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4703 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4705 * som.[ch]: Do not include libhppa.h in som.c, instead include
4708 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4709 include it in elf32-hppa.h.
4711 * som.c (log2): Return -1 on error rather than aborting.
4712 (setup_sections): Bubble up an error from log2.
4714 * Changes to make HP C compiler happy in both traditional
4716 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4718 (bfd_som_set_section_attributes): Use unsigned int rather than
4719 unsigned char to avoid GNU-C extensions.
4720 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4721 or failure rather than aborting on failure.
4723 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4725 (bfd_som_attach_aux_hdr): Add prototype.
4726 (hppa_som-gen_reloc_type): Likewise.
4728 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4729 (hppa_look_for_stubs_in_section): Do not return false on failure
4730 until rest of code is ready to handle it. Abort for now.

4755 action in case where caller specified no argument relocation.
4756 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4757 right in the original relocation and the stub's relocation.
4759 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4760 unused symbols argument.
4762 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4763 than asymbol * for original target symbol. All callers changed.
4764 Set reloc->sym_ptr_ptr appropriately.
4765 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4766 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4767 argument. Use the output symbols when canonicalizing the relocs,
4768 creating them if necessary.
4770 * linker.c (_bfd_generic_link_output_symbols): Do not
4771 rebuild/clobber the output symbols if they already exist.
4773 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4775 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4776 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4777 * bfd-in2.h: Rebuilt.
4779 * srec.c (hex_value): Always set to a size of 256 bytes.

4784 * elf32-hppa.c: Second half of major cleanup. More comments,
4785 PARAMize and staticize rest of functions. Delete unused
4786 functions. Delete unused/unnecessary arguments to some functions.
4787 Group static vars together. Abort for bad errors until we have

4790 #defines for lots of things. Merge two functions which build
4791 linker stubs into a single function (so they can easily share a
4792 ton of common code).

4796 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to

4840 COMPLEX relocation support (it's never used anyway).
4841 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4842 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4843 (elf_hppa_tc_make_sections): Likewise.

5015 (b_out_relax_section): If a section contains no relocations, don't
5016 bother processing them.
5017 (b_out_get_relocated_section_contents): Set reloc_done. Assert
5018 that bfd_get_section_contents returns true. Check that relocs are

5021 that reloc->addend falls between the current source offset and the
5022 raw size of the input section.

6981 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
6983 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
6984 Handle symbol number of zero.
6986 * reloc.c (enum bfd_reloc_code_real): Added
6987 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
6988 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
6989 * bfd-in2.h: Rebuilt.
6990 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
6991 BFD_RELOC_MIPS_LITERAL.
6992 * elf32-mips.c (mips_reloc_map): Handle new relocs.
6993 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
6996 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
6997 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
6998 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
6999 MY_bfd_seclet_link): Define.
7000 (MY_bfd_reloc_type_lookup): Rename from
7001 MY_reloc_howto_type_lookup.
7002 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
7003 (MY(vec)): Use JUMP_TABLE rather than listing functions.
7004 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
7005 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
7006 terms of MY, because that causes a recusive invocation of CAT when
7007 expanded within JUMP_TABLE, and ANSI compilers don't expand
7009 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
7010 MY_reloc_howto_type_lookup, and don't define in terms of MY.
7011 (MY_canonicalize_reloc): Don't define in terms of MY.
7012 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
7013 than listing functions.
7015 Mon Nov 1 09:12:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
7017 * config.bfd: Use m68k-elf for m68*-*-sysv4*.
