4412 _bfd_generic_link_add_symbols but also collect constructors and
4413 destructors by name as collect2 does.
4414 (generic_link_add_symbols): New function, like old
4415 _bfd_generic_link_add_symbols but with collect argument.

4432 extended name table.
4434 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4436 Support for link_order types which generate relocs in order to
4437 support -Ur in the linker.
4438 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4439 from call to _bfd_generic_link_add_one_symbol.
4440 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4441 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4442 instead of bitsize to add_to_set call back.
4443 (_bfd_generic_final_link): Account for link_order relocs when
4444 allocating space for relocations. Handle them in link_order loop.
4445 (_bfd_generic_reloc_link_order): New function.

4463 allocating space for relocations. Handle them in link_order loop.
4464 (ecoff_link_write_external): Set the storage class of a defined
4465 linker created symbol based on the section it is in. Correct
4466 bfd_link_hash_weak case to use .sc rather than .st.

4479 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4481 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4483 * som.c (bfd_section_from_som_symbol): Only to do the value
4484 comparison for function symbols within executables.
4486 * som.c (bfd_section_from_som_symbol): Renamed from
4487 som_section_from_subspace_index. Pass in a native SOM symbol.
4488 For executables, iterate through the sections to find out
4489 which contains the symbol's address rather than using the
4490 symbol_info field. (symbol_info has a different meaning for
4491 dynamicly linked executables.)
4493 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4496 * som.c (som_begin_writing): Fix braino (one call to align
4497 space/subspace data was done unconditionally rather than
4498 just for executables.)
4500 * som.c (som_begin_writing): Align text in all executables to
4501 make HPUX kernel happy. Fixes strip/objcopy for shared
4504 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4506 * som.c (som_begin_writing): Account for alignment needs of
4507 subspaces too when writing executables. Never request a negative
4508 bss size. Fixes some problems with demand paged executables,
4509 still having problems with pure executables and shared executables.
4511 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4513 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4514 bfd_zalloc for rawptr, because later on we may call free, not
4517 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4518 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4519 * cisco-core.c: New file.
4520 * Makefile.in: Change accordingly.
4521 * configure.in: Recognize cisco_core_vec.
4522 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4523 * targets.c: Add cisco_core_vec.
4524 * bfd-in2.h: Rebuilt.
4526 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4528 * som.h (som_copyable_section_data_struct): New structure
4529 containing all the private section information which needs
4530 to be copied from input section to output section during
4532 (som_section_data_struct): Remove several fields now in
4533 som_copyable_section_data_struct. Make the space and
4534 subspace dictionaries be pointers (to save space when
4535 only reading objects).
4537 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4538 some references changed. Allocate a copyable data stucture if
4539 none exists. Store info into the copyable data structure.
4540 (bfd_som_set_subsection_attributes): Likewise.
4541 (som_is_space, som_is_subspace, som_is_container): New functions.
4542 Use these instead of directly accessing private data.
4543 (som_prep_headers): Allocate space and subspace headers here.
4544 Fill in some fields in the space/subspace headers from the
4546 (som_bfd_copy_private_section_data): Only copy the stuff
4547 that we really need to make objcopy and strip work. Allocate
4548 the copy_data structure for the output bfd before copying.
4550 * som.h (struct som_exec_data): New structure to hold exec
4551 info that must be preserved when running objcopy/strip.
4552 (struct somdata): Add new "exec_data" field and accessor
4553 macro. Add some comments on how the various fields are used.
4554 (som_section_data_struct): Make is_space and is_subspace bitfields.
4555 Delete unused subspace_index. All references now use the
4556 target_index field within the section structure itself.
4558 * som.c (make_unique_section): Delete unused declaration.
4559 (som_bfd_copy_private_bfd_data): New function.
4560 (som_object_setup): Allocate space for and save exec information
4561 that needs to be copied during objcopy/strip.
4562 (som_mkobject): Do not allocate space for a file header here.
4563 It is not used when only reading SOM objects.
4564 (som_prep_headers): Allocate space for and attach a file header
4565 to the output bfd. For executables, use the saved system_id
4566 value rather than trying to guess the right value. Do not abort
4567 wwhen setting file_hdr->entry* for executables.
4568 (som_begin_writing): For executables, set the exec_entry and
4570 (som_copy_private_backend_section_data): Always return a value.
4572 * libhppa.h (PA_PAGESIZE): Define.
4574 * som.c (SOM_ALIGN): Define.
4575 (som_begin_writing): If writing an executable, initialize all
4576 fields in the exec header to zero. Update fields in the exec
4577 header as sizes of loadable subspaces are computed. Carefully
4578 preserve alignments when building executables. Actually write the
4579 exec after all the fields are filled in.
4581 * Better long-filename handling. Reads SOM ABI compliant extended
4582 names, but doesn't quite write compliant extended names yet.
4583 * som.c (som_slurp_extended_name_table): Delete function. The
4584 generic code will handle things correctly.
4585 (som_slurp_armap): Seek to the beginning of the next member.
4586 (normalize): New function.
4587 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4588 name table into account when computing the file offsets in the
4589 SOM dictionary. Make sure to align to an even boundary.
4590 (som_write_armap): Initialize the checksum to zero.
4591 (ar_maxchars): Fix. Opps.
4593 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4595 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4596 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4598 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4600 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4601 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4602 * bfd-in2.h: Regenerated.
4604 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4605 this was also named trad_unix_bfd_copy_private_bfd_data.
4607 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4609 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4610 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4611 returns NULL, it is not an error. It's possible that some of
4612 these checks are not necessary (because the size can never be
4613 zero), but putting in the checks is the conservative thing to do
4614 in light of the fact that some of these malloc calls replaced
4615 unchecked alloca calls, in which a zero argument would work fine.
4617 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4619 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4620 duplicate definition.
4621 (osf_core_bfd_is_local_label): Define.
4623 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4624 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4625 failure indication, it merely means there are no relocs.
4627 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4628 after NAME, since SunOS /bin/cc can't handle it.
4630 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4632 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4633 From sukes@glue.umd.edu (Tasuki Hirata).
4635 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4637 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4638 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4639 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4641 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4643 * som.c (som_prep_for_fixups): Detect section symbols based
4644 on either the lack of private data or the symbol flags. Do not
4645 munge section symbol names anymore -- they no longer confuse GDB.
4646 (som_begin_writing): Leave space for an exec header if writing
4648 (som_slurp_symbol_table): Recognize both forms of section symbol
4649 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4650 section symbols to be the name of the section they represent.
4651 Debugging symbols begin with "L$0\001", not just "L$".
4653 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4655 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4657 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4658 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4659 and bfd_is_local_label.
4661 * targets.c: Add new entries to the bfd_target structure.
4663 * bfd.c (bfd_copy_private_bfd_data): New definition.
4665 * section.c (bfd_copy_private_section_data): New definition.
4667 * syms.c (bfd_is_local_label): New definition.
4669 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4671 * libbfd.c (bfd_generic_is_local_label): New function.
4673 * *-core.c: Provide default definitions for new functions in
4674 the target vector which all point to bfd_false.
4676 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4677 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4678 Default new vectors for copying private backend data to bfd_true.
4679 Default new vector for determining if a symbol is a local label
4680 to bfd_generic_is_local_label.
4682 * som.c (som_bfd_copy_private_section_data): New function.
4683 (som_bfd_is_local_label): New function.
4684 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4686 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4688 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4690 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4692 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4695 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4696 Indent some of them to GNU standards.
4698 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4699 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4700 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4701 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4702 Update copyright years.
4704 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4706 * som.c (som_prep_for_fixups): A relocation involving the section
4707 symbol for the *ABS* section is really a relocation involving
4709 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4710 undefined symbols. Correctly distinguish between debugger symbols
4711 and section symbols.
4713 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4714 for spaces and subspaces.
4716 * som.c (som_bfd_count_ar_symbols): Fix typo.
4718 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4719 HAS_RELOC based on the object's magic number.
4720 (make_unique_section): Delete function. BFD and its users are
4721 prepared to handle multiple sections with the same name.
4722 (setup_sections): Allocate space on the BFD's obstack to hold
4723 section names. Use bfd_make_setion_anyway rather than the
4724 obsolete make_unique_section.
4725 (som_prep_headers): Choose the correct SOM magic number based
4727 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4729 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4731 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4732 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4733 * Makefile.in, configure.in: Corresponding changes.

4737 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
4739 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4741 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4742 is always located at the start of the data section to allow
4743 recovery of the dynamic info from a stripped executable.
4744 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4747 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4749 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4750 cruft (like the #pragma alloca for AIX).
4751 In addition to that problem, the C alloca calls xmalloc, which
4752 means checking for being out of memory can't work right. The
4753 following changes remove all uses of alloca from BFD.
4754 * hosts/solaris2.h: Remove alloca cruft.
4755 * som.c: Replace alloca with a fixed size auto array.
4756 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

5104 bother processing them.
5105 (b_out_get_relocated_section_contents): Set reloc_done. Assert

5808 The sparc (and possibly other?) NLM format requires a different
5809 way to write exports, so add a write_export field to the backend
5810 data (and set it to NULL for everything but the sparc).

5976 sym_filepos as well.
5977 (ecoff_get_extr): Use ifdmap instead of ifdbase.

6054 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
6055 different, so there is no point to providing a generic one.
6056 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
6057 in the backend accessor macros; that should no longer be possible.
