1856 symbol when no dynamic object was seen, initialize the contents of
1857 the .got section. For a R_386_GOT32 against a local symbol, only
1858 create a R_386_RELATIVE reloc when generating a shared object.

1867 (elf32_sparc_create_dynamic_sections): Don't set the size of the

1871 a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
1872 Only create the .rela.got section, and only make space for a
1873 reloc, for a global symbol or when generating a shared object.
1874 Set the alignment of the .rela.got section to 2. For a

1877 permit ELF_LINK_HASH_NEDS_PLT non dynamic symbols. Create a
1878 procedure linkage table for such symbols. But, if no dynamic
1879 objects were seen, never create a PLT entry. Initialize the size
1880 of the .plt section.

1886 symbol when no dynamic object was seen, initialize the contents of
1887 the .got section. For a GOT reloc against a local symbol, only

1889 Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
1890 create a PLT entry as a R_SPARC_WDISP30 reloc.
1891 (elf32_sparc_finish_dynamic_sections): Only fiddle with the
1892 dynamic entries and the PLT if we saw a dynamic object.

5277 in executables left by the HP linker. Does not rely on subspace
5278 alignments as subspaces are *NOT* guaranteed to be properly

5281 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5283 * som.c (som_get_section_contents): New function. Do not try

5329 required by expansions. Set s and unset h when converting a reloc
5330 from undefined to section. Change handling of PC relative relocs:
5331 if against a section, they are correct in the object file, if
5332 against an external symbol they are pcrel_offset.
5333 (mips_relax_section): New function.
5334 (mips_relax_pcrel16): New function.

5420 reloc, used in embedded PIC code.
5421 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
5422 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

5428 link_order loop. Use _bfd_generic_link_add_symbols_collect for
5429 add_symbls entry point.
5431 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
5432 counting relocs. Set SEC_RELOC flag for any section which has

5460 extended name table.
5462 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5464 Support for link_order types which generate relocs in order to
5465 support -Ur in the linker.
5466 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
5467 from call to _bfd_generic_link_add_one_symbol.
5468 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
5469 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
5470 instead of bitsize to add_to_set call back.
5471 (_bfd_generic_final_link): Account for link_order relocs when
5472 allocating space for relocations. Handle them in link_order loop.
5473 (_bfd_generic_reloc_link_order): New function.

5490 (ecoff_bfd_final_link): Account for link_order relocs when
5491 allocating space for relocations. Handle them in link_order loop.
5492 (ecoff_link_write_external): Set the storage class of a defined
5493 linker created symbol based on the section it is in. Correct
5494 bfd_link_hash_weak case to use .sc rather than .st.
5495 (ecoff_reloc_link_order): New function.
5496 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
5498 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

5503 * cisco-core.c (cisco_core_file_p): Only pass one argument to
5504 bfd_zmalloc. Free a pointer, not a union.
5505 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
5507 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5509 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
5511 * som.c (bfd_section_from_som_symbol): Only to do the value
5512 comparison for function symbols within executables.
5514 * som.c (bfd_section_from_som_symbol): Renamed from
5515 som_section_from_subspace_index. Pass in a native SOM symbol.
5516 For executables, iterate through the sections to find out
5517 which contains the symbol's address rather than using the
5518 symbol_info field. (symbol_info has a different meaning for
5519 dynamicly linked executables.)
5521 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
5524 * som.c (som_begin_writing): Fix braino (one call to align
5525 space/subspace data was done unconditionally rather than
5526 just for executables.)
5528 * som.c (som_begin_writing): Align text in all executables to
5529 make HPUX kernel happy. Fixes strip/objcopy for shared
5532 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5534 * som.c (som_begin_writing): Account for alignment needs of
5535 subspaces too when writing executables. Never request a negative
5536 bss size. Fixes some problems with demand paged executables,
5537 still having problems with pure executables and shared executables.
5539 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5541 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
5542 bfd_zalloc for rawptr, because later on we may call free, not
5545 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
5546 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
5547 * cisco-core.c: New file.
5548 * Makefile.in: Change accordingly.
5549 * configure.in: Recognize cisco_core_vec.
5550 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
5551 * targets.c: Add cisco_core_vec.
5552 * bfd-in2.h: Rebuilt.
5554 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5556 * som.h (som_copyable_section_data_struct): New structure
5557 containing all the private section information which needs
5558 to be copied from input section to output section during
5560 (som_section_data_struct): Remove several fields now in
5561 som_copyable_section_data_struct. Make the space and
5562 subspace dictionaries be pointers (to save space when
5563 only reading objects).
5565 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5566 some references changed. Allocate a copyable data stucture if
5567 none exists. Store info into the copyable data structure.
5568 (bfd_som_set_subsection_attributes): Likewise.
5569 (som_is_space, som_is_subspace, som_is_container): New functions.
5570 Use these instead of directly accessing private data.
5571 (som_prep_headers): Allocate space and subspace headers here.
5572 Fill in some fields in the space/subspace headers from the
5574 (som_bfd_copy_private_section_data): Only copy the stuff
5575 that we really need to make objcopy and strip work. Allocate
5576 the copy_data structure for the output bfd before copying.
5578 * som.h (struct som_exec_data): New structure to hold exec
5579 info that must be preserved when running objcopy/strip.
5580 (struct somdata): Add new "exec_data" field and accessor
5581 macro. Add some comments on how the various fields are used.
5582 (som_section_data_struct): Make is_space and is_subspace bitfields.
5583 Delete unused subspace_index. All references now use the
5584 target_index field within the section structure itself.
5586 * som.c (make_unique_section): Delete unused declaration.
5587 (som_bfd_copy_private_bfd_data): New function.
5588 (som_object_setup): Allocate space for and save exec information
5589 that needs to be copied during objcopy/strip.
5590 (som_mkobject): Do not allocate space for a file header here.
5591 It is not used when only reading SOM objects.
5592 (som_prep_headers): Allocate space for and attach a file header
5593 to the output bfd. For executables, use the saved system_id
5594 value rather than trying to guess the right value. Do not abort
5595 wwhen setting file_hdr->entry* for executables.
5596 (som_begin_writing): For executables, set the exec_entry and
5598 (som_copy_private_backend_section_data): Always return a value.
5600 * libhppa.h (PA_PAGESIZE): Define.
5602 * som.c (SOM_ALIGN): Define.
5603 (som_begin_writing): If writing an executable, initialize all
5604 fields in the exec header to zero. Update fields in the exec
5605 header as sizes of loadable subspaces are computed. Carefully
5606 preserve alignments when building executables. Actually write the
5607 exec after all the fields are filled in.
5609 * Better long-filename handling. Reads SOM ABI compliant extended
5610 names, but doesn't quite write compliant extended names yet.
5611 * som.c (som_slurp_extended_name_table): Delete function. The
5612 generic code will handle things correctly.
5613 (som_slurp_armap): Seek to the beginning of the next member.
5614 (normalize): New function.
5615 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5616 name table into account when computing the file offsets in the
5617 SOM dictionary. Make sure to align to an even boundary.
5618 (som_write_armap): Initialize the checksum to zero.
5619 (ar_maxchars): Fix. Opps.
5621 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5623 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5624 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5626 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5628 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5629 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5630 * bfd-in2.h: Regenerated.
5632 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5633 this was also named trad_unix_bfd_copy_private_bfd_data.
5635 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5637 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5638 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5639 returns NULL, it is not an error. It's possible that some of
5640 these checks are not necessary (because the size can never be
5641 zero), but putting in the checks is the conservative thing to do
5642 in light of the fact that some of these malloc calls replaced
5643 unchecked alloca calls, in which a zero argument would work fine.
5645 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5647 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5648 duplicate definition.
5649 (osf_core_bfd_is_local_label): Define.
5651 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5652 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5653 failure indication, it merely means there are no relocs.
5655 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5656 after NAME, since SunOS /bin/cc can't handle it.
5658 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5660 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5661 From sukes@glue.umd.edu (Tasuki Hirata).
5663 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5665 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5666 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5667 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5669 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5671 * som.c (som_prep_for_fixups): Detect section symbols based
5672 on either the lack of private data or the symbol flags. Do not
5673 munge section symbol names anymore -- they no longer confuse GDB.
5674 (som_begin_writing): Leave space for an exec header if writing
5676 (som_slurp_symbol_table): Recognize both forms of section symbol
5677 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"

6698 bfd_som_set_subsection_attributes): Change parameters from char
6699 to int. Following a prototype with an old-style function definition

6809 undefined, look it up in the linker hash table.
6811 * aoutx.h (translate_symbol_table): The string index 0 has a

6836 The sparc (and possibly other?) NLM format requires a different
6837 way to write exports, so add a write_export field to the backend
6838 data (and set it to NULL for everything but the sparc).
