1354 in executables left by the HP linker. Does not rely on subspace
1355 alignments as subspaces are *NOT* guaranteed to be properly

1358 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1360 * som.c (som_get_section_contents): New function. Do not try

1406 required by expansions. Set s and unset h when converting a reloc
1407 from undefined to section. Change handling of PC relative relocs:
1408 if against a section, they are correct in the object file, if
1409 against an external symbol they are pcrel_offset.
1410 (mips_relax_section): New function.
1411 (mips_relax_pcrel16): New function.

1497 reloc, used in embedded PIC code.
1498 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

1505 link_order loop. Use _bfd_generic_link_add_symbols_collect for
1506 add_symbls entry point.
1508 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1509 counting relocs. Set SEC_RELOC flag for any section which has

1537 extended name table.
1539 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1541 Support for link_order types which generate relocs in order to
1542 support -Ur in the linker.
1543 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1544 from call to _bfd_generic_link_add_one_symbol.
1545 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1546 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1547 instead of bitsize to add_to_set call back.
1548 (_bfd_generic_final_link): Account for link_order relocs when
1549 allocating space for relocations. Handle them in link_order loop.
1550 (_bfd_generic_reloc_link_order): New function.

1567 (ecoff_bfd_final_link): Account for link_order relocs when
1568 allocating space for relocations. Handle them in link_order loop.
1569 (ecoff_link_write_external): Set the storage class of a defined
1570 linker created symbol based on the section it is in. Correct
1571 bfd_link_hash_weak case to use .sc rather than .st.
1572 (ecoff_reloc_link_order): New function.
1573 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

1584 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1586 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1588 * som.c (bfd_section_from_som_symbol): Only to do the value
1589 comparison for function symbols within executables.
1591 * som.c (bfd_section_from_som_symbol): Renamed from
1592 som_section_from_subspace_index. Pass in a native SOM symbol.
1593 For executables, iterate through the sections to find out
1594 which contains the symbol's address rather than using the
1595 symbol_info field. (symbol_info has a different meaning for
1596 dynamicly linked executables.)
1598 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1601 * som.c (som_begin_writing): Fix braino (one call to align
1602 space/subspace data was done unconditionally rather than
1603 just for executables.)
1605 * som.c (som_begin_writing): Align text in all executables to
1606 make HPUX kernel happy. Fixes strip/objcopy for shared
1609 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1611 * som.c (som_begin_writing): Account for alignment needs of
1612 subspaces too when writing executables. Never request a negative
1613 bss size. Fixes some problems with demand paged executables,
1614 still having problems with pure executables and shared executables.
1616 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1618 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1619 bfd_zalloc for rawptr, because later on we may call free, not
1622 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1623 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1624 * cisco-core.c: New file.
1625 * Makefile.in: Change accordingly.
1626 * configure.in: Recognize cisco_core_vec.
1627 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1628 * targets.c: Add cisco_core_vec.
1629 * bfd-in2.h: Rebuilt.
1631 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1633 * som.h (som_copyable_section_data_struct): New structure
1634 containing all the private section information which needs
1635 to be copied from input section to output section during
1637 (som_section_data_struct): Remove several fields now in
1638 som_copyable_section_data_struct. Make the space and
1639 subspace dictionaries be pointers (to save space when
1640 only reading objects).
1642 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1643 some references changed. Allocate a copyable data stucture if
1644 none exists. Store info into the copyable data structure.
1645 (bfd_som_set_subsection_attributes): Likewise.
1646 (som_is_space, som_is_subspace, som_is_container): New functions.
1647 Use these instead of directly accessing private data.
1648 (som_prep_headers): Allocate space and subspace headers here.
1649 Fill in some fields in the space/subspace headers from the
1651 (som_bfd_copy_private_section_data): Only copy the stuff
1652 that we really need to make objcopy and strip work. Allocate
1653 the copy_data structure for the output bfd before copying.
1655 * som.h (struct som_exec_data): New structure to hold exec
1656 info that must be preserved when running objcopy/strip.
1657 (struct somdata): Add new "exec_data" field and accessor
1658 macro. Add some comments on how the various fields are used.
1659 (som_section_data_struct): Make is_space and is_subspace bitfields.
1660 Delete unused subspace_index. All references now use the
1661 target_index field within the section structure itself.
1663 * som.c (make_unique_section): Delete unused declaration.
1664 (som_bfd_copy_private_bfd_data): New function.
1665 (som_object_setup): Allocate space for and save exec information
1666 that needs to be copied during objcopy/strip.
1667 (som_mkobject): Do not allocate space for a file header here.
1668 It is not used when only reading SOM objects.
1669 (som_prep_headers): Allocate space for and attach a file header
1670 to the output bfd. For executables, use the saved system_id
1671 value rather than trying to guess the right value. Do not abort
1672 wwhen setting file_hdr->entry* for executables.
1673 (som_begin_writing): For executables, set the exec_entry and
1675 (som_copy_private_backend_section_data): Always return a value.
1677 * libhppa.h (PA_PAGESIZE): Define.
1679 * som.c (SOM_ALIGN): Define.
1680 (som_begin_writing): If writing an executable, initialize all
1681 fields in the exec header to zero. Update fields in the exec
1682 header as sizes of loadable subspaces are computed. Carefully
1683 preserve alignments when building executables. Actually write the
1684 exec after all the fields are filled in.
1686 * Better long-filename handling. Reads SOM ABI compliant extended
1687 names, but doesn't quite write compliant extended names yet.
1688 * som.c (som_slurp_extended_name_table): Delete function. The
1689 generic code will handle things correctly.
1690 (som_slurp_armap): Seek to the beginning of the next member.
1691 (normalize): New function.
1692 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1693 name table into account when computing the file offsets in the
1694 SOM dictionary. Make sure to align to an even boundary.
1695 (som_write_armap): Initialize the checksum to zero.
1696 (ar_maxchars): Fix. Opps.
1698 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1700 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1701 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1703 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1705 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1706 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1707 * bfd-in2.h: Regenerated.
1709 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1710 this was also named trad_unix_bfd_copy_private_bfd_data.
1712 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1714 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1715 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1716 returns NULL, it is not an error. It's possible that some of
1717 these checks are not necessary (because the size can never be
1718 zero), but putting in the checks is the conservative thing to do
1719 in light of the fact that some of these malloc calls replaced
1720 unchecked alloca calls, in which a zero argument would work fine.
1722 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1724 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1725 duplicate definition.
1726 (osf_core_bfd_is_local_label): Define.
1728 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1729 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1730 failure indication, it merely means there are no relocs.
1732 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1733 after NAME, since SunOS /bin/cc can't handle it.
1735 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1737 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1738 From sukes@glue.umd.edu (Tasuki Hirata).
1740 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1742 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1743 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1744 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1746 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1748 * som.c (som_prep_for_fixups): Detect section symbols based
1749 on either the lack of private data or the symbol flags. Do not
1750 munge section symbol names anymore -- they no longer confuse GDB.

2697 _bfd_generic_link_write_global_symbol): Don't require that all
2698 references to a common symbol be themselves common symbols.

2775 bfd_som_set_subsection_attributes): Change parameters from char
2776 to int. Following a prototype with an old-style function definition

2886 undefined, look it up in the linker hash table.
2888 * aoutx.h (translate_symbol_table): The string index 0 has a

2913 The sparc (and possibly other?) NLM format requires a different
2914 way to write exports, so add a write_export field to the backend
2915 data (and set it to NULL for everything but the sparc).
