1346 in executables left by the HP linker. Does not rely on subspace
1347 alignments as subspaces are *NOT* guaranteed to be properly

1399 from undefined to section. Change handling of PC relative relocs:
1400 if against a section, they are correct in the object file, if
1401 against an external symbol they are pcrel_offset.
1402 (mips_relax_section): New function.
1403 (mips_relax_pcrel16): New function.
1404 (ecoff_bfd_relax_section): Define.

1489 reloc, used in embedded PIC code.
1490 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

1497 link_order loop. Use _bfd_generic_link_add_symbols_collect for
1498 add_symbls entry point.
1500 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1501 counting relocs. Set SEC_RELOC flag for any section which has

1529 extended name table.
1531 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1533 Support for link_order types which generate relocs in order to
1534 support -Ur in the linker.
1535 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1536 from call to _bfd_generic_link_add_one_symbol.
1537 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1538 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1539 instead of bitsize to add_to_set call back.
1540 (_bfd_generic_final_link): Account for link_order relocs when
1541 allocating space for relocations. Handle them in link_order loop.
1542 (_bfd_generic_reloc_link_order): New function.

1559 (ecoff_bfd_final_link): Account for link_order relocs when
1560 allocating space for relocations. Handle them in link_order loop.
1561 (ecoff_link_write_external): Set the storage class of a defined
1562 linker created symbol based on the section it is in. Correct
1563 bfd_link_hash_weak case to use .sc rather than .st.
1564 (ecoff_reloc_link_order): New function.
1565 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1567 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1573 bfd_zmalloc. Free a pointer, not a union.
1574 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1576 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1578 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1580 * som.c (bfd_section_from_som_symbol): Only to do the value
1581 comparison for function symbols within executables.
1583 * som.c (bfd_section_from_som_symbol): Renamed from
1584 som_section_from_subspace_index. Pass in a native SOM symbol.
1585 For executables, iterate through the sections to find out
1586 which contains the symbol's address rather than using the
1587 symbol_info field. (symbol_info has a different meaning for
1588 dynamicly linked executables.)
1590 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1593 * som.c (som_begin_writing): Fix braino (one call to align
1594 space/subspace data was done unconditionally rather than
1595 just for executables.)
1597 * som.c (som_begin_writing): Align text in all executables to
1598 make HPUX kernel happy. Fixes strip/objcopy for shared
1601 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1603 * som.c (som_begin_writing): Account for alignment needs of
1604 subspaces too when writing executables. Never request a negative
1605 bss size. Fixes some problems with demand paged executables,
1606 still having problems with pure executables and shared executables.
1608 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1610 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1611 bfd_zalloc for rawptr, because later on we may call free, not
1614 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1615 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1616 * cisco-core.c: New file.
1617 * Makefile.in: Change accordingly.
1618 * configure.in: Recognize cisco_core_vec.
1619 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1620 * targets.c: Add cisco_core_vec.
1621 * bfd-in2.h: Rebuilt.
1623 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1625 * som.h (som_copyable_section_data_struct): New structure
1626 containing all the private section information which needs
1627 to be copied from input section to output section during
1629 (som_section_data_struct): Remove several fields now in
1630 som_copyable_section_data_struct. Make the space and
1631 subspace dictionaries be pointers (to save space when
1632 only reading objects).
1634 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1635 some references changed. Allocate a copyable data stucture if
1636 none exists. Store info into the copyable data structure.
1637 (bfd_som_set_subsection_attributes): Likewise.
1638 (som_is_space, som_is_subspace, som_is_container): New functions.
1639 Use these instead of directly accessing private data.
1640 (som_prep_headers): Allocate space and subspace headers here.
1641 Fill in some fields in the space/subspace headers from the
1643 (som_bfd_copy_private_section_data): Only copy the stuff
1644 that we really need to make objcopy and strip work. Allocate
1645 the copy_data structure for the output bfd before copying.
1647 * som.h (struct som_exec_data): New structure to hold exec
1648 info that must be preserved when running objcopy/strip.
1649 (struct somdata): Add new "exec_data" field and accessor
1650 macro. Add some comments on how the various fields are used.
1651 (som_section_data_struct): Make is_space and is_subspace bitfields.
1652 Delete unused subspace_index. All references now use the
1653 target_index field within the section structure itself.
1655 * som.c (make_unique_section): Delete unused declaration.
1656 (som_bfd_copy_private_bfd_data): New function.
1657 (som_object_setup): Allocate space for and save exec information
1658 that needs to be copied during objcopy/strip.
1659 (som_mkobject): Do not allocate space for a file header here.
1660 It is not used when only reading SOM objects.
1661 (som_prep_headers): Allocate space for and attach a file header
1662 to the output bfd. For executables, use the saved system_id
1663 value rather than trying to guess the right value. Do not abort
1664 wwhen setting file_hdr->entry* for executables.
1665 (som_begin_writing): For executables, set the exec_entry and
1667 (som_copy_private_backend_section_data): Always return a value.
1669 * libhppa.h (PA_PAGESIZE): Define.
1671 * som.c (SOM_ALIGN): Define.
1672 (som_begin_writing): If writing an executable, initialize all
1673 fields in the exec header to zero. Update fields in the exec
1674 header as sizes of loadable subspaces are computed. Carefully
1675 preserve alignments when building executables. Actually write the
1676 exec after all the fields are filled in.
1678 * Better long-filename handling. Reads SOM ABI compliant extended
1679 names, but doesn't quite write compliant extended names yet.
1680 * som.c (som_slurp_extended_name_table): Delete function. The
1681 generic code will handle things correctly.
1682 (som_slurp_armap): Seek to the beginning of the next member.
1683 (normalize): New function.
1684 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1685 name table into account when computing the file offsets in the
1686 SOM dictionary. Make sure to align to an even boundary.
1687 (som_write_armap): Initialize the checksum to zero.
1688 (ar_maxchars): Fix. Opps.
1690 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1692 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1693 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1695 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1697 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1698 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1699 * bfd-in2.h: Regenerated.
1701 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1702 this was also named trad_unix_bfd_copy_private_bfd_data.
1704 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1706 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1707 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1708 returns NULL, it is not an error. It's possible that some of
1709 these checks are not necessary (because the size can never be
1710 zero), but putting in the checks is the conservative thing to do
1711 in light of the fact that some of these malloc calls replaced
1712 unchecked alloca calls, in which a zero argument would work fine.
1714 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1716 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1717 duplicate definition.
1718 (osf_core_bfd_is_local_label): Define.
1720 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1721 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1722 failure indication, it merely means there are no relocs.
1724 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1725 after NAME, since SunOS /bin/cc can't handle it.
1727 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1729 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1730 From sukes@glue.umd.edu (Tasuki Hirata).
1732 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1734 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1735 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1736 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1738 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1740 * som.c (som_prep_for_fixups): Detect section symbols based
1741 on either the lack of private data or the symbol flags. Do not
1742 munge section symbol names anymore -- they no longer confuse GDB.
1743 (som_begin_writing): Leave space for an exec header if writing
1745 (som_slurp_symbol_table): Recognize both forms of section symbol
1746 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1747 section symbols to be the name of the section they represent.
1748 Debugging symbols begin with "L$0\001", not just "L$".

2878 undefined, look it up in the linker hash table.
2880 * aoutx.h (translate_symbol_table): The string index 0 has a

2905 The sparc (and possibly other?) NLM format requires a different
2906 way to write exports, so add a write_export field to the backend
2907 data (and set it to NULL for everything but the sparc).
