5286 required by expansions. Set s and unset h when converting a reloc
5287 from undefined to section. Change handling of PC relative relocs:
5288 if against a section, they are correct in the object file, if
5289 against an external symbol they are pcrel_offset.
5290 (mips_relax_section): New function.
5291 (mips_relax_pcrel16): New function.

5377 reloc, used in embedded PIC code.
5378 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

5417 extended name table.
5419 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5421 Support for link_order types which generate relocs in order to
5422 support -Ur in the linker.
5423 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5424 from call to _bfd_generic_link_add_one_symbol.
5425 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5426 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5427 instead of bitsize to add_to_set call back.
5428 (_bfd_generic_final_link): Account for link_order relocs when
5429 allocating space for relocations. Handle them in link_order loop.
5430 (_bfd_generic_reloc_link_order): New function.

5448 allocating space for relocations. Handle them in link_order loop.
5449 (ecoff_link_write_external): Set the storage class of a defined
5450 linker created symbol based on the section it is in. Correct
5451 bfd_link_hash_weak case to use .sc rather than .st.
5452 (ecoff_reloc_link_order): New function.
5453 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5455 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

5461 bfd_zmalloc. Free a pointer, not a union.
5462 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5464 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5466 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5468 * som.c (bfd_section_from_som_symbol): Only to do the value
5469 comparison for function symbols within executables.
5471 * som.c (bfd_section_from_som_symbol): Renamed from
5472 som_section_from_subspace_index. Pass in a native SOM symbol.
5473 For executables, iterate through the sections to find out
5474 which contains the symbol's address rather than using the
5475 symbol_info field. (symbol_info has a different meaning for
5476 dynamicly linked executables.)
5478 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5481 * som.c (som_begin_writing): Fix braino (one call to align
5482 space/subspace data was done unconditionally rather than
5483 just for executables.)
5485 * som.c (som_begin_writing): Align text in all executables to
5486 make HPUX kernel happy. Fixes strip/objcopy for shared
5489 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5491 * som.c (som_begin_writing): Account for alignment needs of
5492 subspaces too when writing executables. Never request a negative
5493 bss size. Fixes some problems with demand paged executables,
5494 still having problems with pure executables and shared executables.
5496 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5498 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5499 bfd_zalloc for rawptr, because later on we may call free, not
5502 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5503 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5504 * cisco-core.c: New file.

5511 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5513 * som.h (som_copyable_section_data_struct): New structure
5514 containing all the private section information which needs
5515 to be copied from input section to output section during
5517 (som_section_data_struct): Remove several fields now in
5518 som_copyable_section_data_struct. Make the space and
5519 subspace dictionaries be pointers (to save space when
5520 only reading objects).
5522 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5523 some references changed. Allocate a copyable data stucture if
5524 none exists. Store info into the copyable data structure.
5525 (bfd_som_set_subsection_attributes): Likewise.
5526 (som_is_space, som_is_subspace, som_is_container): New functions.
5527 Use these instead of directly accessing private data.
5528 (som_prep_headers): Allocate space and subspace headers here.
5529 Fill in some fields in the space/subspace headers from the
5531 (som_bfd_copy_private_section_data): Only copy the stuff
5532 that we really need to make objcopy and strip work. Allocate
5533 the copy_data structure for the output bfd before copying.
5535 * som.h (struct som_exec_data): New structure to hold exec
5536 info that must be preserved when running objcopy/strip.
5537 (struct somdata): Add new "exec_data" field and accessor
5538 macro. Add some comments on how the various fields are used.
5539 (som_section_data_struct): Make is_space and is_subspace bitfields.
5540 Delete unused subspace_index. All references now use the
5541 target_index field within the section structure itself.
5543 * som.c (make_unique_section): Delete unused declaration.
5544 (som_bfd_copy_private_bfd_data): New function.
5545 (som_object_setup): Allocate space for and save exec information
5546 that needs to be copied during objcopy/strip.
5547 (som_mkobject): Do not allocate space for a file header here.
5548 It is not used when only reading SOM objects.
5549 (som_prep_headers): Allocate space for and attach a file header
5550 to the output bfd. For executables, use the saved system_id
5551 value rather than trying to guess the right value. Do not abort
5552 wwhen setting file_hdr->entry* for executables.
5553 (som_begin_writing): For executables, set the exec_entry and
5555 (som_copy_private_backend_section_data): Always return a value.
5557 * libhppa.h (PA_PAGESIZE): Define.
5559 * som.c (SOM_ALIGN): Define.
5560 (som_begin_writing): If writing an executable, initialize all
5561 fields in the exec header to zero. Update fields in the exec
5562 header as sizes of loadable subspaces are computed. Carefully
5563 preserve alignments when building executables. Actually write the
5564 exec after all the fields are filled in.
5566 * Better long-filename handling. Reads SOM ABI compliant extended
5567 names, but doesn't quite write compliant extended names yet.
5568 * som.c (som_slurp_extended_name_table): Delete function. The
5569 generic code will handle things correctly.
5570 (som_slurp_armap): Seek to the beginning of the next member.
5571 (normalize): New function.
5572 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5573 name table into account when computing the file offsets in the
5574 SOM dictionary. Make sure to align to an even boundary.
5575 (som_write_armap): Initialize the checksum to zero.
5576 (ar_maxchars): Fix. Opps.
5578 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5580 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5581 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5583 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5585 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5586 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5587 * bfd-in2.h: Regenerated.
5589 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5590 this was also named trad_unix_bfd_copy_private_bfd_data.
5592 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5594 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5595 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5596 returns NULL, it is not an error. It's possible that some of
5597 these checks are not necessary (because the size can never be
5598 zero), but putting in the checks is the conservative thing to do
5599 in light of the fact that some of these malloc calls replaced
5600 unchecked alloca calls, in which a zero argument would work fine.
5602 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5604 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5605 duplicate definition.
5606 (osf_core_bfd_is_local_label): Define.
5608 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5609 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5610 failure indication, it merely means there are no relocs.
5612 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5613 after NAME, since SunOS /bin/cc can't handle it.
5615 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5617 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5618 From sukes@glue.umd.edu (Tasuki Hirata).
5620 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5622 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5623 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5624 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5626 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5628 * som.c (som_prep_for_fixups): Detect section symbols based
5629 on either the lack of private data or the symbol flags. Do not
5630 munge section symbol names anymore -- they no longer confuse GDB.
5631 (som_begin_writing): Leave space for an exec header if writing
5633 (som_slurp_symbol_table): Recognize both forms of section symbol
5634 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5635 section symbols to be the name of the section they represent.
5636 Debugging symbols begin with "L$0\001", not just "L$".
5638 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5640 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5642 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5643 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5644 and bfd_is_local_label.
5646 * targets.c: Add new entries to the bfd_target structure.
5648 * bfd.c (bfd_copy_private_bfd_data): New definition.

5659 the target vector which all point to bfd_false.
5661 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5662 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5663 Default new vectors for copying private backend data to bfd_true.
5664 Default new vector for determining if a symbol is a local label
5665 to bfd_generic_is_local_label.
5667 * som.c (som_bfd_copy_private_section_data): New function.
5668 (som_bfd_is_local_label): New function.
5669 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5671 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5673 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5675 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5677 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)

5735 cruft (like the #pragma alloca for AIX).
5736 In addition to that problem, the C alloca calls xmalloc, which

6793 The sparc (and possibly other?) NLM format requires a different
6794 way to write exports, so add a write_export field to the backend
6795 data (and set it to NULL for everything but the sparc).
