4320 required by expansions. Set s and unset h when converting a reloc
4321 from undefined to section. Change handling of PC relative relocs:
4322 if against a section, they are correct in the object file, if
4323 against an external symbol they are pcrel_offset.

4453 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4455 Support for link_order types which generate relocs in order to
4456 support -Ur in the linker.
4457 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4458 from call to _bfd_generic_link_add_one_symbol.
4459 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4460 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4461 instead of bitsize to add_to_set call back.
4462 (_bfd_generic_final_link): Account for link_order relocs when
4463 allocating space for relocations. Handle them in link_order loop.

4482 allocating space for relocations. Handle them in link_order loop.
4483 (ecoff_link_write_external): Set the storage class of a defined
4484 linker created symbol based on the section it is in. Correct
4485 bfd_link_hash_weak case to use .sc rather than .st.

4503 comparison for function symbols within executables.
4505 * som.c (bfd_section_from_som_symbol): Renamed from
4506 som_section_from_subspace_index. Pass in a native SOM symbol.
4507 For executables, iterate through the sections to find out
4508 which contains the symbol's address rather than using the
4509 symbol_info field. (symbol_info has a different meaning for
4510 dynamicly linked executables.)
4512 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4515 * som.c (som_begin_writing): Fix braino (one call to align
4516 space/subspace data was done unconditionally rather than
4517 just for executables.)
4519 * som.c (som_begin_writing): Align text in all executables to
4520 make HPUX kernel happy. Fixes strip/objcopy for shared
4523 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4525 * som.c (som_begin_writing): Account for alignment needs of
4526 subspaces too when writing executables. Never request a negative
4527 bss size. Fixes some problems with demand paged executables,
4528 still having problems with pure executables and shared executables.
4530 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4532 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4533 bfd_zalloc for rawptr, because later on we may call free, not
4536 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4537 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4538 * cisco-core.c: New file.

4545 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4547 * som.h (som_copyable_section_data_struct): New structure
4548 containing all the private section information which needs
4549 to be copied from input section to output section during
4551 (som_section_data_struct): Remove several fields now in
4552 som_copyable_section_data_struct. Make the space and
4553 subspace dictionaries be pointers (to save space when
4554 only reading objects).
4556 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4557 some references changed. Allocate a copyable data stucture if
4558 none exists. Store info into the copyable data structure.
4559 (bfd_som_set_subsection_attributes): Likewise.
4560 (som_is_space, som_is_subspace, som_is_container): New functions.
4561 Use these instead of directly accessing private data.
4562 (som_prep_headers): Allocate space and subspace headers here.
4563 Fill in some fields in the space/subspace headers from the
4565 (som_bfd_copy_private_section_data): Only copy the stuff
4566 that we really need to make objcopy and strip work. Allocate
4567 the copy_data structure for the output bfd before copying.
4569 * som.h (struct som_exec_data): New structure to hold exec
4570 info that must be preserved when running objcopy/strip.
4571 (struct somdata): Add new "exec_data" field and accessor
4572 macro. Add some comments on how the various fields are used.
4573 (som_section_data_struct): Make is_space and is_subspace bitfields.
4574 Delete unused subspace_index. All references now use the
4575 target_index field within the section structure itself.
4577 * som.c (make_unique_section): Delete unused declaration.
4578 (som_bfd_copy_private_bfd_data): New function.
4579 (som_object_setup): Allocate space for and save exec information
4580 that needs to be copied during objcopy/strip.
4581 (som_mkobject): Do not allocate space for a file header here.
4582 It is not used when only reading SOM objects.
4583 (som_prep_headers): Allocate space for and attach a file header
4584 to the output bfd. For executables, use the saved system_id
4585 value rather than trying to guess the right value. Do not abort
4586 wwhen setting file_hdr->entry* for executables.
4587 (som_begin_writing): For executables, set the exec_entry and
4589 (som_copy_private_backend_section_data): Always return a value.
4591 * libhppa.h (PA_PAGESIZE): Define.
4593 * som.c (SOM_ALIGN): Define.
4594 (som_begin_writing): If writing an executable, initialize all
4595 fields in the exec header to zero. Update fields in the exec
4596 header as sizes of loadable subspaces are computed. Carefully
4597 preserve alignments when building executables. Actually write the
4598 exec after all the fields are filled in.
4600 * Better long-filename handling. Reads SOM ABI compliant extended
4601 names, but doesn't quite write compliant extended names yet.
4602 * som.c (som_slurp_extended_name_table): Delete function. The
4603 generic code will handle things correctly.
4604 (som_slurp_armap): Seek to the beginning of the next member.
4605 (normalize): New function.
4606 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4607 name table into account when computing the file offsets in the
4608 SOM dictionary. Make sure to align to an even boundary.
4609 (som_write_armap): Initialize the checksum to zero.
4610 (ar_maxchars): Fix. Opps.

4614 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4615 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

4619 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4620 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4621 * bfd-in2.h: Regenerated.
4623 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4624 this was also named trad_unix_bfd_copy_private_bfd_data.
4626 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4628 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4629 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4630 returns NULL, it is not an error. It's possible that some of
4631 these checks are not necessary (because the size can never be
4632 zero), but putting in the checks is the conservative thing to do
4633 in light of the fact that some of these malloc calls replaced
4634 unchecked alloca calls, in which a zero argument would work fine.
4636 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4638 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4639 duplicate definition.
4640 (osf_core_bfd_is_local_label): Define.
4642 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4643 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4644 failure indication, it merely means there are no relocs.
4646 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4647 after NAME, since SunOS /bin/cc can't handle it.
4649 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4651 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4652 From sukes@glue.umd.edu (Tasuki Hirata).
4654 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4656 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4657 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4658 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4660 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4662 * som.c (som_prep_for_fixups): Detect section symbols based
4663 on either the lack of private data or the symbol flags. Do not
4664 munge section symbol names anymore -- they no longer confuse GDB.
4665 (som_begin_writing): Leave space for an exec header if writing
4667 (som_slurp_symbol_table): Recognize both forms of section symbol
4668 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4669 section symbols to be the name of the section they represent.
4670 Debugging symbols begin with "L$0\001", not just "L$".
4672 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4674 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.

4677 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4678 and bfd_is_local_label.

4696 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4697 Default new vectors for copying private backend data to bfd_true.
4698 Default new vector for determining if a symbol is a local label
4699 to bfd_generic_is_local_label.
4701 * som.c (som_bfd_copy_private_section_data): New function.
4702 (som_bfd_is_local_label): New function.
4703 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4705 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4707 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4709 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4711 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4714 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4715 Indent some of them to GNU standards.
4717 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4718 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

4720 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4721 Update copyright years.
4723 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4725 * som.c (som_prep_for_fixups): A relocation involving the section
4726 symbol for the *ABS* section is really a relocation involving
4728 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4729 undefined symbols. Correctly distinguish between debugger symbols
4730 and section symbols.
4732 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4733 for spaces and subspaces.
4735 * som.c (som_bfd_count_ar_symbols): Fix typo.
4737 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4738 HAS_RELOC based on the object's magic number.
4739 (make_unique_section): Delete function. BFD and its users are
4740 prepared to handle multiple sections with the same name.
4741 (setup_sections): Allocate space on the BFD's obstack to hold
4742 section names. Use bfd_make_setion_anyway rather than the
4743 obsolete make_unique_section.
4744 (som_prep_headers): Choose the correct SOM magic number based
4746 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4760 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4761 is always located at the start of the data section to allow

4769 cruft (like the #pragma alloca for AIX).
4770 In addition to that problem, the C alloca calls xmalloc, which
4771 means checking for being out of memory can't work right. The
4772 following changes remove all uses of alloca from BFD.

5123 bother processing them.
5124 (b_out_get_relocated_section_contents): Set reloc_done. Assert
5125 that bfd_get_section_contents returns true. Check that relocs are

5208 Make all callers of malloc or realloc (including via obstacks)
5209 check the result for NULL. Most set bfd_error to no_memory and
5210 return in that case; a few are harder to fix, and are marked

5214 hppa_elf_build_long_branch_stub): Check bfd_make_empty_symbol return.

5827 The sparc (and possibly other?) NLM format requires a different
5828 way to write exports, so add a write_export field to the backend
5829 data (and set it to NULL for everything but the sparc).

5995 sym_filepos as well.
5996 (ecoff_get_extr): Use ifdmap instead of ifdbase.

6068 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

6071 * configure.in (nlm32_alpha_vec): Set target64 to true.
6073 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
6074 different, so there is no point to providing a generic one.
6075 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
6076 in the backend accessor macros; that should no longer be possible.
6077 * targets.c (target_vector): Removed nlm32_big_generic_vec,
