1567 support -Ur in the linker.
1568 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1569 from call to _bfd_generic_link_add_one_symbol.
1570 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1571 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1572 instead of bitsize to add_to_set call back.
1573 (_bfd_generic_final_link): Account for link_order relocs when
1574 allocating space for relocations. Handle them in link_order loop.

1614 comparison for function symbols within executables.
1616 * som.c (bfd_section_from_som_symbol): Renamed from
1617 som_section_from_subspace_index. Pass in a native SOM symbol.
1618 For executables, iterate through the sections to find out
1619 which contains the symbol's address rather than using the
1620 symbol_info field. (symbol_info has a different meaning for
1621 dynamicly linked executables.)
1623 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1626 * som.c (som_begin_writing): Fix braino (one call to align
1627 space/subspace data was done unconditionally rather than
1628 just for executables.)
1630 * som.c (som_begin_writing): Align text in all executables to
1631 make HPUX kernel happy. Fixes strip/objcopy for shared
1634 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1636 * som.c (som_begin_writing): Account for alignment needs of
1637 subspaces too when writing executables. Never request a negative
1638 bss size. Fixes some problems with demand paged executables,
1639 still having problems with pure executables and shared executables.
1641 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1643 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1644 bfd_zalloc for rawptr, because later on we may call free, not
1647 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1648 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.

1658 * som.h (som_copyable_section_data_struct): New structure
1659 containing all the private section information which needs
1660 to be copied from input section to output section during
1662 (som_section_data_struct): Remove several fields now in
1663 som_copyable_section_data_struct. Make the space and
1664 subspace dictionaries be pointers (to save space when
1665 only reading objects).
1667 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1668 some references changed. Allocate a copyable data stucture if
1669 none exists. Store info into the copyable data structure.
1670 (bfd_som_set_subsection_attributes): Likewise.
1671 (som_is_space, som_is_subspace, som_is_container): New functions.
1672 Use these instead of directly accessing private data.
1673 (som_prep_headers): Allocate space and subspace headers here.
1674 Fill in some fields in the space/subspace headers from the
1676 (som_bfd_copy_private_section_data): Only copy the stuff
1677 that we really need to make objcopy and strip work. Allocate
1678 the copy_data structure for the output bfd before copying.
1680 * som.h (struct som_exec_data): New structure to hold exec
1681 info that must be preserved when running objcopy/strip.
1682 (struct somdata): Add new "exec_data" field and accessor
1683 macro. Add some comments on how the various fields are used.
1684 (som_section_data_struct): Make is_space and is_subspace bitfields.
1685 Delete unused subspace_index. All references now use the
1686 target_index field within the section structure itself.
1688 * som.c (make_unique_section): Delete unused declaration.
1689 (som_bfd_copy_private_bfd_data): New function.
1690 (som_object_setup): Allocate space for and save exec information
1691 that needs to be copied during objcopy/strip.
1692 (som_mkobject): Do not allocate space for a file header here.
1693 It is not used when only reading SOM objects.
1694 (som_prep_headers): Allocate space for and attach a file header
1695 to the output bfd. For executables, use the saved system_id
1696 value rather than trying to guess the right value. Do not abort
1697 wwhen setting file_hdr->entry* for executables.
1698 (som_begin_writing): For executables, set the exec_entry and
1700 (som_copy_private_backend_section_data): Always return a value.
1702 * libhppa.h (PA_PAGESIZE): Define.
1704 * som.c (SOM_ALIGN): Define.
1705 (som_begin_writing): If writing an executable, initialize all
1706 fields in the exec header to zero. Update fields in the exec
1707 header as sizes of loadable subspaces are computed. Carefully
1708 preserve alignments when building executables. Actually write the
1709 exec after all the fields are filled in.
1711 * Better long-filename handling. Reads SOM ABI compliant extended
1712 names, but doesn't quite write compliant extended names yet.
1713 * som.c (som_slurp_extended_name_table): Delete function. The
1714 generic code will handle things correctly.
1715 (som_slurp_armap): Seek to the beginning of the next member.
1716 (normalize): New function.
1717 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1718 name table into account when computing the file offsets in the
1719 SOM dictionary. Make sure to align to an even boundary.
1720 (som_write_armap): Initialize the checksum to zero.
1721 (ar_maxchars): Fix. Opps.
1723 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1725 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1726 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1728 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

1731 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1732 * bfd-in2.h: Regenerated.
1734 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1735 this was also named trad_unix_bfd_copy_private_bfd_data.
1737 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1739 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1740 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1741 returns NULL, it is not an error. It's possible that some of
1742 these checks are not necessary (because the size can never be
1743 zero), but putting in the checks is the conservative thing to do
1744 in light of the fact that some of these malloc calls replaced
1745 unchecked alloca calls, in which a zero argument would work fine.
1747 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1749 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1750 duplicate definition.

1753 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1754 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1755 failure indication, it merely means there are no relocs.
1757 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1758 after NAME, since SunOS /bin/cc can't handle it.

1767 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1768 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1769 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).

1773 * som.c (som_prep_for_fixups): Detect section symbols based

1836 * som.c (som_prep_for_fixups): A relocation involving the section
1837 symbol for the *ABS* section is really a relocation involving
1839 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1840 undefined symbols. Correctly distinguish between debugger symbols
1841 and section symbols.

1844 for spaces and subspaces.
1846 * som.c (som_bfd_count_ar_symbols): Fix typo.

1880 cruft (like the #pragma alloca for AIX).
1881 In addition to that problem, the C alloca calls xmalloc, which
1882 means checking for being out of memory can't work right. The
1883 following changes remove all uses of alloca from BFD.

1927 include it in elf32-hppa.h.
1929 * som.c (log2): Return -1 on error rather than aborting.
1930 (setup_sections): Bubble up an error from log2.
1932 * Changes to make HP C compiler happy in both traditional
1934 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

2218 Tue Feb 15 19:39:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2220 * section.c (bfd_get_section_contents): Since this function reads
2221 unrelocated contents, the section's raw size is always the one to
2222 use for bounds checking.

2225 link_order size field against cooked size, not raw size, of input
2228 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just

2231 current offset in the section plus the number of bytes of padding
2232 that will actually be retained.
2233 (b_out_relax_section): If a section contains no relocations, don't
2234 bother processing them.
2235 (b_out_get_relocated_section_contents): Set reloc_done. Assert

2239 that reloc->addend falls between the current source offset and the
2240 raw size of the input section.
2242 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
2243 bout. Default with no version number is still bout. Support

2673 fields to bitfields. Added fields fix_value and fix_scnlen.
2674 (sec_to_styp_flags): If STYP_DEBUG is defined, use it rather than
2675 STYP_INFO for the type of a section named .debug.
2676 (coff_add_missing_symbols): Don't define if RS6000COFF_C.
2677 (coff_write_object_contents): If RS6000COFF_C, don't call

2694 debug_string_size is not 0, check that it matches the size of the
2696 (coff_get_normalized_symtab): Clear new fix_value and fix_scnlen
2697 fields. If the string offset is 0, always use an empty string as
2699 (coff_make_empty_symbol): Zero out the symbol structure.

2718 symbol has a value in the ECOFF symbol but not in the BFD symbol,
2719 keep the value in the ECOFF symbol. This helps gas.
2721 * linker.c (_bfd_generic_link_output_symbols,
2722 _bfd_generic_link_write_global_symbol): Don't require that all
2723 references to a common symbol be themselves common symbols.

2767 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
2768 (only testing for m68k and vax at the moment); do verify that the
2769 preprocessor didn't trash the arch name inside the string version.
2770 Don't print out "pagesize =" line that prevents output from
2771 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
2773 * Makefile.in (aout-params.h): Pass gen-aout a dummy target name.

2800 bfd_som_set_subsection_attributes): Change parameters from char
2801 to int. Following a prototype with an old-style function definition

2908 use get_value to get the symbol value and check for undefined
2910 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
2911 undefined, look it up in the linker hash table.
2913 * aoutx.h (translate_symbol_table): The string index 0 has a

2938 The sparc (and possibly other?) NLM format requires a different
2939 way to write exports, so add a write_export field to the backend
2940 data (and set it to NULL for everything but the sparc).
