1578 from call to _bfd_generic_link_add_one_symbol.
1579 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.

1627 For executables, iterate through the sections to find out
1628 which contains the symbol's address rather than using the
1629 symbol_info field. (symbol_info has a different meaning for
1630 dynamicly linked executables.)
1632 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1635 * som.c (som_begin_writing): Fix braino (one call to align
1636 space/subspace data was done unconditionally rather than
1637 just for executables.)
1639 * som.c (som_begin_writing): Align text in all executables to
1640 make HPUX kernel happy. Fixes strip/objcopy for shared
1643 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1645 * som.c (som_begin_writing): Account for alignment needs of
1646 subspaces too when writing executables. Never request a negative
1647 bss size. Fixes some problems with demand paged executables,

1668 containing all the private section information which needs
1669 to be copied from input section to output section during
1671 (som_section_data_struct): Remove several fields now in
1672 som_copyable_section_data_struct. Make the space and
1673 subspace dictionaries be pointers (to save space when
1674 only reading objects).
1676 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1677 some references changed. Allocate a copyable data stucture if
1678 none exists. Store info into the copyable data structure.
1679 (bfd_som_set_subsection_attributes): Likewise.
1680 (som_is_space, som_is_subspace, som_is_container): New functions.
1681 Use these instead of directly accessing private data.
1682 (som_prep_headers): Allocate space and subspace headers here.
1683 Fill in some fields in the space/subspace headers from the
1685 (som_bfd_copy_private_section_data): Only copy the stuff
1686 that we really need to make objcopy and strip work. Allocate
1687 the copy_data structure for the output bfd before copying.
1689 * som.h (struct som_exec_data): New structure to hold exec
1690 info that must be preserved when running objcopy/strip.
1691 (struct somdata): Add new "exec_data" field and accessor
1692 macro. Add some comments on how the various fields are used.
1693 (som_section_data_struct): Make is_space and is_subspace bitfields.
1694 Delete unused subspace_index. All references now use the
1695 target_index field within the section structure itself.
1697 * som.c (make_unique_section): Delete unused declaration.
1698 (som_bfd_copy_private_bfd_data): New function.
1699 (som_object_setup): Allocate space for and save exec information
1700 that needs to be copied during objcopy/strip.
1701 (som_mkobject): Do not allocate space for a file header here.
1702 It is not used when only reading SOM objects.
1703 (som_prep_headers): Allocate space for and attach a file header
1704 to the output bfd. For executables, use the saved system_id
1705 value rather than trying to guess the right value. Do not abort
1706 wwhen setting file_hdr->entry* for executables.
1707 (som_begin_writing): For executables, set the exec_entry and
1709 (som_copy_private_backend_section_data): Always return a value.
1711 * libhppa.h (PA_PAGESIZE): Define.
1713 * som.c (SOM_ALIGN): Define.
1714 (som_begin_writing): If writing an executable, initialize all
1715 fields in the exec header to zero. Update fields in the exec
1716 header as sizes of loadable subspaces are computed. Carefully
1717 preserve alignments when building executables. Actually write the
1718 exec after all the fields are filled in.
1720 * Better long-filename handling. Reads SOM ABI compliant extended
1721 names, but doesn't quite write compliant extended names yet.
1722 * som.c (som_slurp_extended_name_table): Delete function. The
1723 generic code will handle things correctly.
1724 (som_slurp_armap): Seek to the beginning of the next member.
1725 (normalize): New function.
1726 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1727 name table into account when computing the file offsets in the
1728 SOM dictionary. Make sure to align to an even boundary.
1729 (som_write_armap): Initialize the checksum to zero.
1730 (ar_maxchars): Fix. Opps.

1741 * bfd-in2.h: Regenerated.
1743 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1744 this was also named trad_unix_bfd_copy_private_bfd_data.
1746 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1748 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1749 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1750 returns NULL, it is not an error. It's possible that some of
1751 these checks are not necessary (because the size can never be
1752 zero), but putting in the checks is the conservative thing to do
1753 in light of the fact that some of these malloc calls replaced
1754 unchecked alloca calls, in which a zero argument would work fine.
1756 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1758 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1759 duplicate definition.

1763 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1764 failure indication, it merely means there are no relocs.
1766 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1767 after NAME, since SunOS /bin/cc can't handle it.
1769 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1771 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

1776 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1777 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1778 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1780 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1782 * som.c (som_prep_for_fixups): Detect section symbols based
1783 on either the lack of private data or the symbol flags. Do not
1784 munge section symbol names anymore -- they no longer confuse GDB.
1785 (som_begin_writing): Leave space for an exec header if writing
1787 (som_slurp_symbol_table): Recognize both forms of section symbol
1788 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1789 section symbols to be the name of the section they represent.
1790 Debugging symbols begin with "L$0\001", not just "L$".

1816 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1817 Default new vectors for copying private backend data to bfd_true.

1819 to bfd_generic_is_local_label.
1821 * som.c (som_bfd_copy_private_section_data): New function.
1822 (som_bfd_is_local_label): New function.

1831 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1834 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1835 Indent some of them to GNU standards.
1837 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1838 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

1843 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1845 * som.c (som_prep_for_fixups): A relocation involving the section
1846 symbol for the *ABS* section is really a relocation involving
1848 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1849 undefined symbols. Correctly distinguish between debugger symbols
1850 and section symbols.
1852 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1853 for spaces and subspaces.
1855 * som.c (som_bfd_count_ar_symbols): Fix typo.
1857 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1858 HAS_RELOC based on the object's magic number.
1859 (make_unique_section): Delete function. BFD and its users are
1860 prepared to handle multiple sections with the same name.
1861 (setup_sections): Allocate space on the BFD's obstack to hold
1862 section names. Use bfd_make_setion_anyway rather than the

1886 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1888 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1889 cruft (like the #pragma alloca for AIX).
1890 In addition to that problem, the C alloca calls xmalloc, which
1891 means checking for being out of memory can't work right. The
1892 following changes remove all uses of alloca from BFD.
1893 * hosts/solaris2.h: Remove alloca cruft.
1894 * som.c: Replace alloca with a fixed size auto array.

1935 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1936 include it in elf32-hppa.h.
1938 * som.c (log2): Return -1 on error rather than aborting.
1939 (setup_sections): Bubble up an error from log2.
1941 * Changes to make HP C compiler happy in both traditional
1943 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

2227 Tue Feb 15 19:39:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2229 * section.c (bfd_get_section_contents): Since this function reads
2230 unrelocated contents, the section's raw size is always the one to
2231 use for bounds checking.

2234 link_order size field against cooked size, not raw size, of input
2237 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
2239 (aligncode): When shrinking, the addend should be set to the
2240 current offset in the section plus the number of bytes of padding
2241 that will actually be retained.
2242 (b_out_relax_section): If a section contains no relocations, don't
2243 bother processing them.
2244 (b_out_get_relocated_section_contents): Set reloc_done. Assert

2247 (b_out_get_relocated_section_contents, case ALIGNDONE): Assert
2248 that reloc->addend falls between the current source offset and the
2249 raw size of the input section.
2251 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
2252 bout. Default with no version number is still bout. Support

2777 (only testing for m68k and vax at the moment); do verify that the
2778 preprocessor didn't trash the arch name inside the string version.

2809 bfd_som_set_subsection_attributes): Change parameters from char
2810 to int. Following a prototype with an old-style function definition

2917 use get_value to get the symbol value and check for undefined
2919 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
2920 undefined, look it up in the linker hash table.
2922 * aoutx.h (translate_symbol_table): The string index 0 has a

2947 The sparc (and possibly other?) NLM format requires a different
2948 way to write exports, so add a write_export field to the backend
2949 data (and set it to NULL for everything but the sparc).
