1342 * som.c (som_begin_writing): New approach at dealing with holes
1343 in executables left by the HP linker. Does not rely on subspace
1344 alignments as subspaces are *NOT* guaranteed to be properly

1395 required by expansions. Set s and unset h when converting a reloc
1396 from undefined to section. Change handling of PC relative relocs:
1397 if against a section, they are correct in the object file, if
1398 against an external symbol they are pcrel_offset.
1399 (mips_relax_section): New function.
1400 (mips_relax_pcrel16): New function.
1401 (ecoff_bfd_relax_section): Define.

1486 reloc, used in embedded PIC code.
1487 (mips_adjust_reloc_in): Change sanity check to permit new reloc.
1488 (mips_bfd_reloc_type_lookup): Turn BFD_RELOC_16_PCREL_S2 into

1494 link_order loop. Use _bfd_generic_link_add_symbols_collect for
1495 add_symbls entry point.
1497 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1498 counting relocs. Set SEC_RELOC flag for any section which has

1526 extended name table.
1528 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1530 Support for link_order types which generate relocs in order to
1531 support -Ur in the linker.
1532 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1533 from call to _bfd_generic_link_add_one_symbol.
1534 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1535 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1536 instead of bitsize to add_to_set call back.
1537 (_bfd_generic_final_link): Account for link_order relocs when
1538 allocating space for relocations. Handle them in link_order loop.
1539 (_bfd_generic_reloc_link_order): New function.

1544 argument from declaration.
1545 (_bfd_generic_reloc_link_order): Declare.

1556 (ecoff_bfd_final_link): Account for link_order relocs when
1557 allocating space for relocations. Handle them in link_order loop.
1558 (ecoff_link_write_external): Set the storage class of a defined
1559 linker created symbol based on the section it is in. Correct
1560 bfd_link_hash_weak case to use .sc rather than .st.
1561 (ecoff_reloc_link_order): New function.
1562 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1564 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1570 bfd_zmalloc. Free a pointer, not a union.
1571 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1573 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1575 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1577 * som.c (bfd_section_from_som_symbol): Only to do the value
1578 comparison for function symbols within executables.
1580 * som.c (bfd_section_from_som_symbol): Renamed from
1581 som_section_from_subspace_index. Pass in a native SOM symbol.
1582 For executables, iterate through the sections to find out
1583 which contains the symbol's address rather than using the
1584 symbol_info field. (symbol_info has a different meaning for
1585 dynamicly linked executables.)
1587 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1590 * som.c (som_begin_writing): Fix braino (one call to align
1591 space/subspace data was done unconditionally rather than
1592 just for executables.)
1594 * som.c (som_begin_writing): Align text in all executables to
1595 make HPUX kernel happy. Fixes strip/objcopy for shared
1598 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1600 * som.c (som_begin_writing): Account for alignment needs of
1601 subspaces too when writing executables. Never request a negative
1602 bss size. Fixes some problems with demand paged executables,
1603 still having problems with pure executables and shared executables.
1605 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1607 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1608 bfd_zalloc for rawptr, because later on we may call free, not
1611 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1612 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1613 * cisco-core.c: New file.
1614 * Makefile.in: Change accordingly.
1615 * configure.in: Recognize cisco_core_vec.
1616 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1617 * targets.c: Add cisco_core_vec.
1618 * bfd-in2.h: Rebuilt.
1620 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1622 * som.h (som_copyable_section_data_struct): New structure
1623 containing all the private section information which needs
1624 to be copied from input section to output section during
1626 (som_section_data_struct): Remove several fields now in
1627 som_copyable_section_data_struct. Make the space and
1628 subspace dictionaries be pointers (to save space when
1629 only reading objects).
1631 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1632 some references changed. Allocate a copyable data stucture if
1633 none exists. Store info into the copyable data structure.
1634 (bfd_som_set_subsection_attributes): Likewise.
1635 (som_is_space, som_is_subspace, som_is_container): New functions.
1636 Use these instead of directly accessing private data.
1637 (som_prep_headers): Allocate space and subspace headers here.
1638 Fill in some fields in the space/subspace headers from the
1640 (som_bfd_copy_private_section_data): Only copy the stuff
1641 that we really need to make objcopy and strip work. Allocate
1642 the copy_data structure for the output bfd before copying.
1644 * som.h (struct som_exec_data): New structure to hold exec
1645 info that must be preserved when running objcopy/strip.
1646 (struct somdata): Add new "exec_data" field and accessor
1647 macro. Add some comments on how the various fields are used.
1648 (som_section_data_struct): Make is_space and is_subspace bitfields.
1649 Delete unused subspace_index. All references now use the
1650 target_index field within the section structure itself.
1652 * som.c (make_unique_section): Delete unused declaration.
1653 (som_bfd_copy_private_bfd_data): New function.
1654 (som_object_setup): Allocate space for and save exec information
1655 that needs to be copied during objcopy/strip.
1656 (som_mkobject): Do not allocate space for a file header here.
1657 It is not used when only reading SOM objects.
1658 (som_prep_headers): Allocate space for and attach a file header
1659 to the output bfd. For executables, use the saved system_id
1660 value rather than trying to guess the right value. Do not abort
1661 wwhen setting file_hdr->entry* for executables.
1662 (som_begin_writing): For executables, set the exec_entry and
1664 (som_copy_private_backend_section_data): Always return a value.
1666 * libhppa.h (PA_PAGESIZE): Define.
1668 * som.c (SOM_ALIGN): Define.
1669 (som_begin_writing): If writing an executable, initialize all
1670 fields in the exec header to zero. Update fields in the exec
1671 header as sizes of loadable subspaces are computed. Carefully
1672 preserve alignments when building executables. Actually write the
1673 exec after all the fields are filled in.
1675 * Better long-filename handling. Reads SOM ABI compliant extended
1676 names, but doesn't quite write compliant extended names yet.
1677 * som.c (som_slurp_extended_name_table): Delete function. The
1678 generic code will handle things correctly.
1679 (som_slurp_armap): Seek to the beginning of the next member.
1680 (normalize): New function.
1681 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1682 name table into account when computing the file offsets in the
1683 SOM dictionary. Make sure to align to an even boundary.
1684 (som_write_armap): Initialize the checksum to zero.
1685 (ar_maxchars): Fix. Opps.
1687 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1689 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1690 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1692 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1694 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1695 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1696 * bfd-in2.h: Regenerated.
1698 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1699 this was also named trad_unix_bfd_copy_private_bfd_data.
1701 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1703 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1704 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1705 returns NULL, it is not an error. It's possible that some of
1706 these checks are not necessary (because the size can never be
1707 zero), but putting in the checks is the conservative thing to do
1708 in light of the fact that some of these malloc calls replaced
1709 unchecked alloca calls, in which a zero argument would work fine.
1711 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1713 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1714 duplicate definition.
1715 (osf_core_bfd_is_local_label): Define.
1717 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1718 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1719 failure indication, it merely means there are no relocs.
1721 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1722 after NAME, since SunOS /bin/cc can't handle it.
1724 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1726 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1727 From sukes@glue.umd.edu (Tasuki Hirata).
1729 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1731 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1732 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1733 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1735 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1737 * som.c (som_prep_for_fixups): Detect section symbols based
1738 on either the lack of private data or the symbol flags. Do not
1739 munge section symbol names anymore -- they no longer confuse GDB.
1740 (som_begin_writing): Leave space for an exec header if writing
1742 (som_slurp_symbol_table): Recognize both forms of section symbol
1743 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1744 section symbols to be the name of the section they represent.
1745 Debugging symbols begin with "L$0\001", not just "L$".

2764 bfd_som_set_subsection_attributes): Change parameters from char
2765 to int. Following a prototype with an old-style function definition

2875 undefined, look it up in the linker hash table.
2877 * aoutx.h (translate_symbol_table): The string index 0 has a

2902 The sparc (and possibly other?) NLM format requires a different
2903 way to write exports, so add a write_export field to the backend
2904 data (and set it to NULL for everything but the sparc).
