4325 * libbfd-in.h (_bfd_generic_link_add_symbols_collect): Declare.
4326 * libbfd.h: Rebuilt.
4328 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4330 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
4331 for first character in an extended name.
4332 (_bfd_write_archive_contents): If ar_padchar == '/', then use
4333 "//" as the name of the special archive member holding the
4334 extended name table.
4336 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4338 Support for link_order types which generate relocs in order to
4339 support -Ur in the linker.
4340 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4341 from call to _bfd_generic_link_add_one_symbol.
4342 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4343 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4344 instead of bitsize to add_to_set call back.
4345 (_bfd_generic_final_link): Account for link_order relocs when
4346 allocating space for relocations. Handle them in link_order loop.
4347 (_bfd_generic_reloc_link_order): New function.
4348 (_bfd_default_link_order): If a reloc_link_order is seen here,
4350 (_bfd_count_link_order_relocs): New function.
4351 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
4352 argument from declaration.
4353 (_bfd_generic_reloc_link_order): Declare.
4354 (_bfd_count_link_order_relocs): Declare.
4355 * libbfd.h: Rebuilt.
4356 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
4357 call to _bfd_generic_link_add_one_symbol.
4358 (NAME(aout,final_link)): Account for link_order relocs when
4359 allocating space for relocations. Handle them after handling all
4361 (aout_link_reloc_link_order): New function.
4362 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
4363 call to _bfd_generic_link_add_one_symbol.
4364 (ecoff_bfd_final_link): Account for link_order relocs when
4365 allocating space for relocations. Handle them in link_order loop.
4366 (ecoff_link_write_external): Set the storage class of a defined
4367 linker created symbol based on the section it is in. Correct
4368 bfd_link_hash_weak case to use .sc rather than .st.
4369 (ecoff_reloc_link_order): New function.
4370 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4372 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
4374 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
4377 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4378 bfd_zmalloc. Free a pointer, not a union.
4379 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4381 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4383 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4385 * som.c (bfd_section_from_som_symbol): Only to do the value
4386 comparison for function symbols within executables.
4388 * som.c (bfd_section_from_som_symbol): Renamed from
4389 som_section_from_subspace_index. Pass in a native SOM symbol.
4390 For executables, iterate through the sections to find out
4391 which contains the symbol's address rather than using the
4392 symbol_info field. (symbol_info has a different meaning for
4393 dynamicly linked executables.)
4395 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4398 * som.c (som_begin_writing): Fix braino (one call to align
4399 space/subspace data was done unconditionally rather than
4400 just for executables.)
4402 * som.c (som_begin_writing): Align text in all executables to
4403 make HPUX kernel happy. Fixes strip/objcopy for shared
4406 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4408 * som.c (som_begin_writing): Account for alignment needs of
4409 subspaces too when writing executables. Never request a negative
4410 bss size. Fixes some problems with demand paged executables,
4411 still having problems with pure executables and shared executables.
4413 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4415 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4416 bfd_zalloc for rawptr, because later on we may call free, not
4419 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4420 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4421 * cisco-core.c: New file.
4422 * Makefile.in: Change accordingly.
4423 * configure.in: Recognize cisco_core_vec.
4424 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4425 * targets.c: Add cisco_core_vec.
4426 * bfd-in2.h: Rebuilt.
4428 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4430 * som.h (som_copyable_section_data_struct): New structure
4431 containing all the private section information which needs
4432 to be copied from input section to output section during
4434 (som_section_data_struct): Remove several fields now in
4435 som_copyable_section_data_struct. Make the space and
4436 subspace dictionaries be pointers (to save space when
4437 only reading objects).
4439 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4440 some references changed. Allocate a copyable data stucture if
4441 none exists. Store info into the copyable data structure.
4442 (bfd_som_set_subsection_attributes): Likewise.
4443 (som_is_space, som_is_subspace, som_is_container): New functions.
4444 Use these instead of directly accessing private data.
4445 (som_prep_headers): Allocate space and subspace headers here.
4446 Fill in some fields in the space/subspace headers from the
4448 (som_bfd_copy_private_section_data): Only copy the stuff
4449 that we really need to make objcopy and strip work. Allocate
4450 the copy_data structure for the output bfd before copying.
4452 * som.h (struct som_exec_data): New structure to hold exec
4453 info that must be preserved when running objcopy/strip.
4454 (struct somdata): Add new "exec_data" field and accessor
4455 macro. Add some comments on how the various fields are used.
4456 (som_section_data_struct): Make is_space and is_subspace bitfields.
4457 Delete unused subspace_index. All references now use the
4458 target_index field within the section structure itself.
4460 * som.c (make_unique_section): Delete unused declaration.
4461 (som_bfd_copy_private_bfd_data): New function.
4462 (som_object_setup): Allocate space for and save exec information
4463 that needs to be copied during objcopy/strip.
4464 (som_mkobject): Do not allocate space for a file header here.
4465 It is not used when only reading SOM objects.
4466 (som_prep_headers): Allocate space for and attach a file header
4467 to the output bfd. For executables, use the saved system_id
4468 value rather than trying to guess the right value. Do not abort
4469 wwhen setting file_hdr->entry* for executables.
4470 (som_begin_writing): For executables, set the exec_entry and
4472 (som_copy_private_backend_section_data): Always return a value.
4474 * libhppa.h (PA_PAGESIZE): Define.
4476 * som.c (SOM_ALIGN): Define.
4477 (som_begin_writing): If writing an executable, initialize all
4478 fields in the exec header to zero. Update fields in the exec
4479 header as sizes of loadable subspaces are computed. Carefully
4480 preserve alignments when building executables. Actually write the
4481 exec after all the fields are filled in.
4483 * Better long-filename handling. Reads SOM ABI compliant extended
4484 names, but doesn't quite write compliant extended names yet.
4485 * som.c (som_slurp_extended_name_table): Delete function. The
4486 generic code will handle things correctly.
4487 (som_slurp_armap): Seek to the beginning of the next member.
4488 (normalize): New function.
4489 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4490 name table into account when computing the file offsets in the
4491 SOM dictionary. Make sure to align to an even boundary.
4492 (som_write_armap): Initialize the checksum to zero.
4493 (ar_maxchars): Fix. Opps.
4495 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4497 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4498 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4500 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4502 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4503 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4504 * bfd-in2.h: Regenerated.
4506 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4507 this was also named trad_unix_bfd_copy_private_bfd_data.
4509 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4511 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4512 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4513 returns NULL, it is not an error. It's possible that some of
4514 these checks are not necessary (because the size can never be
4515 zero), but putting in the checks is the conservative thing to do
4516 in light of the fact that some of these malloc calls replaced
4517 unchecked alloca calls, in which a zero argument would work fine.
4519 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4521 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4522 duplicate definition.
4523 (osf_core_bfd_is_local_label): Define.
4525 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4526 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4527 failure indication, it merely means there are no relocs.
4529 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4530 after NAME, since SunOS /bin/cc can't handle it.
4532 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4534 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4535 From sukes@glue.umd.edu (Tasuki Hirata).
4537 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4539 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4540 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4541 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4543 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4545 * som.c (som_prep_for_fixups): Detect section symbols based
4546 on either the lack of private data or the symbol flags. Do not
4547 munge section symbol names anymore -- they no longer confuse GDB.
4548 (som_begin_writing): Leave space for an exec header if writing
4550 (som_slurp_symbol_table): Recognize both forms of section symbol
4551 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4552 section symbols to be the name of the section they represent.
4553 Debugging symbols begin with "L$0\001", not just "L$".
4555 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4557 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4559 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4560 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4561 and bfd_is_local_label.
4563 * targets.c: Add new entries to the bfd_target structure.
4565 * bfd.c (bfd_copy_private_bfd_data): New definition.
4567 * section.c (bfd_copy_private_section_data): New definition.
4569 * syms.c (bfd_is_local_label): New definition.
4571 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4573 * libbfd.c (bfd_generic_is_local_label): New function.
4575 * *-core.c: Provide default definitions for new functions in
4576 the target vector which all point to bfd_false.
4578 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4579 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4580 Default new vectors for copying private backend data to bfd_true.
4581 Default new vector for determining if a symbol is a local label
4582 to bfd_generic_is_local_label.
4584 * som.c (som_bfd_copy_private_section_data): New function.
4585 (som_bfd_is_local_label): New function.
4586 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4588 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4590 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4592 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4594 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4597 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4598 Indent some of them to GNU standards.
4600 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4601 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4602 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4603 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4604 Update copyright years.
4606 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4608 * som.c (som_prep_for_fixups): A relocation involving the section
4609 symbol for the *ABS* section is really a relocation involving
4611 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4612 undefined symbols. Correctly distinguish between debugger symbols
4613 and section symbols.
4615 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4616 for spaces and subspaces.
4618 * som.c (som_bfd_count_ar_symbols): Fix typo.
4620 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4621 HAS_RELOC based on the object's magic number.
4622 (make_unique_section): Delete function. BFD and its users are
4623 prepared to handle multiple sections with the same name.
4624 (setup_sections): Allocate space on the BFD's obstack to hold
4625 section names. Use bfd_make_setion_anyway rather than the
4626 obsolete make_unique_section.
4627 (som_prep_headers): Choose the correct SOM magic number based
4629 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4631 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4633 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4634 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.

4641 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4643 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4644 is always located at the start of the data section to allow
4645 recovery of the dynamic info from a stripped executable.
4646 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4649 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4651 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4652 cruft (like the #pragma alloca for AIX).
4653 In addition to that problem, the C alloca calls xmalloc, which
4654 means checking for being out of memory can't work right. The
4655 following changes remove all uses of alloca from BFD.
4656 * hosts/solaris2.h: Remove alloca cruft.
4657 * som.c: Replace alloca with a fixed size auto array.
4658 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

4662 * linker.c: Replace alloca with obstack_alloc.
4663 * libbfd.h: Rebuilt.
4665 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4667 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4670 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4672 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4673 Elf*_Off typedefs by their expansion, the typedefs have been
4674 removed from include/elf/internal.h.
4675 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4676 SHT_PROGBITS section.
4678 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4680 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4684 * configure.host: Recognize i[34]86-sequent-*.
4686 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4687 return from bfd_seek indicates an error.
4688 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4689 TRAD_CORE_STACK_OFFSET.
4690 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4691 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4693 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4695 * som.[ch]: Do not include libhppa.h in som.c, instead include
4698 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4699 include it in elf32-hppa.h.
4701 * som.c (log2): Return -1 on error rather than aborting.
4702 (setup_sections): Bubble up an error from log2.
4704 * Changes to make HP C compiler happy in both traditional
4706 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4708 (bfd_som_set_section_attributes): Use unsigned int rather than
4709 unsigned char to avoid GNU-C extensions.
4710 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4711 or failure rather than aborting on failure.
4713 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4715 (bfd_som_attach_aux_hdr): Add prototype.
4716 (hppa_som-gen_reloc_type): Likewise.
4718 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4719 (hppa_look_for_stubs_in_section): Do not return false on failure
4720 until rest of code is ready to handle it. Abort for now.
4722 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4724 * bfd-in2.h: Rebuilt.

4744 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
4745 action in case where caller specified no argument relocation.
4746 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4747 right in the original relocation and the stub's relocation.
4749 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4750 unused symbols argument.
4752 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4753 than asymbol * for original target symbol. All callers changed.
4754 Set reloc->sym_ptr_ptr appropriately.
4755 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4756 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4757 argument. Use the output symbols when canonicalizing the relocs,
4758 creating them if necessary.
4760 * linker.c (_bfd_generic_link_output_symbols): Do not
4761 rebuild/clobber the output symbols if they already exist.
4763 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4765 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4766 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4767 * bfd-in2.h: Rebuilt.
4769 * srec.c (hex_value): Always set to a size of 256 bytes.
4770 (srec_init): Cosmetic changes.
4772 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4774 * elf32-hppa.c: Second half of major cleanup. More comments,
4775 PARAMize and staticize rest of functions. Delete unused
4776 functions. Delete unused/unnecessary arguments to some functions.
4777 Group static vars together. Abort for bad errors until we have
4778 error code propogation working. Work on spacing and indention.

4781 linker stubs into a single function (so they can easily share a
4782 ton of common code).

5005 (b_out_relax_section): If a section contains no relocations, don't
5006 bother processing them.
5007 (b_out_get_relocated_section_contents): Set reloc_done. Assert

5091 Make all callers of malloc or realloc (including via obstacks)
5092 check the result for NULL. Most set bfd_error to no_memory and

6980 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
6981 BFD_RELOC_MIPS_LITERAL.
6982 * elf32-mips.c (mips_reloc_map): Handle new relocs.
6983 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
6986 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
6987 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
6988 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
6989 MY_bfd_seclet_link): Define.
6990 (MY_bfd_reloc_type_lookup): Rename from
6991 MY_reloc_howto_type_lookup.
6992 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
6993 (MY(vec)): Use JUMP_TABLE rather than listing functions.
6994 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
6995 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
6996 terms of MY, because that causes a recusive invocation of CAT when
6997 expanded within JUMP_TABLE, and ANSI compilers don't expand
6999 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
7000 MY_reloc_howto_type_lookup, and don't define in terms of MY.
7001 (MY_canonicalize_reloc): Don't define in terms of MY.
7002 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
7003 than listing functions.
