1654 * elf32-mips.c (mips_elf_final_link): Account for link_order
1655 relocs when allocating space for relocations. Set SEC_RELOC flag
1656 for any section which has relocs. Handle link_order relocs in
1657 link_order loop. Use _bfd_generic_link_add_symbols_collect for
1658 add_symbls entry point.
1659
1660 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before

1664 * linker.c (_bfd_default_link_order): Handle bfd_data_link_order.
1665
1666 * linker.c (_bfd_generic_link_add_symbols): Just call
1667 generic_link_add_symbols.

1683 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1684
1685 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
1686 for first character in an extended name.
1687 (_bfd_write_archive_contents): If ar_padchar == '/', then use
1688 "//" as the name of the special archive member holding the
1689 extended name table.
1690
1691 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1692
1693 Support for link_order types which generate relocs in order to
1694 support -Ur in the linker.

1696 from call to _bfd_generic_link_add_one_symbol.
1697 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.

1699 instead of bitsize to add_to_set call back.
1700 (_bfd_generic_final_link): Account for link_order relocs when
1701 allocating space for relocations. Handle them in link_order loop.
1702 (_bfd_generic_reloc_link_order): New function.
1703 (_bfd_default_link_order): If a reloc_link_order is seen here,
1704 abort.

1712 call to _bfd_generic_link_add_one_symbol.
1713 (NAME(aout,final_link)): Account for link_order relocs when
1714 allocating space for relocations. Handle them after handling all
1715 input BFDs.
1716 (aout_link_reloc_link_order): New function.

1735
1736 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1737
1738 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1739
1740 * som.c (bfd_section_from_som_symbol): Only to do the value
1741 comparison for function symbols within executables.
1742
1743 * som.c (bfd_section_from_som_symbol): Renamed from
1744 som_section_from_subspace_index. Pass in a native SOM symbol.
1745 For executables, iterate through the sections to find out
1746 which contains the symbol's address rather than using the
1747 symbol_info field. (symbol_info has a different meaning for
1748 dynamicly linked executables.)
1749
1750 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1751 bfd_zmalloc.
1752
1753 * som.c (som_begin_writing): Fix braino (one call to align
1754 space/subspace data was done unconditionally rather than
1755 just for executables.)
1756
1757 * som.c (som_begin_writing): Align text in all executables to
1758 make HPUX kernel happy. Fixes strip/objcopy for shared
1759 executables.
1760
1761 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1762
1763 * som.c (som_begin_writing): Account for alignment needs of
1764 subspaces too when writing executables. Never request a negative
1765 bss size. Fixes some problems with demand paged executables,
1766 still having problems with pure executables and shared executables.
1767
1768 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1769
1770 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1771 bfd_zalloc for rawptr, because later on we may call free, not
1772 bfd_release, on it.
1773
1774 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1775 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1776 * cisco-core.c: New file.
1777 * Makefile.in: Change accordingly.

1782
1783 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1784
1785 * som.h (som_copyable_section_data_struct): New structure
1786 containing all the private section information which needs
1787 to be copied from input section to output section during
1788 objcopy or strip.
1789 (som_section_data_struct): Remove several fields now in
1790 som_copyable_section_data_struct. Make the space and
1791 subspace dictionaries be pointers (to save space when
1792 only reading objects).
1793
1794 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1795 some references changed. Allocate a copyable data stucture if
1796 none exists. Store info into the copyable data structure.
1797 (bfd_som_set_subsection_attributes): Likewise.
1798 (som_is_space, som_is_subspace, som_is_container): New functions.
1799 Use these instead of directly accessing private data.
1800 (som_prep_headers): Allocate space and subspace headers here.
1801 Fill in some fields in the space/subspace headers from the
1802 copyable data.
1803 (som_bfd_copy_private_section_data): Only copy the stuff
1804 that we really need to make objcopy and strip work. Allocate
1805 the copy_data structure for the output bfd before copying.
1806
1807 * som.h (struct som_exec_data): New structure to hold exec
1808 info that must be preserved when running objcopy/strip.
1809 (struct somdata): Add new "exec_data" field and accessor
1810 macro. Add some comments on how the various fields are used.
1811 (som_section_data_struct): Make is_space and is_subspace bitfields.
1812 Delete unused subspace_index. All references now use the
1813 target_index field within the section structure itself.
1814
1815 * som.c (make_unique_section): Delete unused declaration.
1816 (som_bfd_copy_private_bfd_data): New function.
1817 (som_object_setup): Allocate space for and save exec information
1818 that needs to be copied during objcopy/strip.
1819 (som_mkobject): Do not allocate space for a file header here.
1820 It is not used when only reading SOM objects.
1821 (som_prep_headers): Allocate space for and attach a file header
1822 to the output bfd. For executables, use the saved system_id
1823 value rather than trying to guess the right value. Do not abort
1824 wwhen setting file_hdr->entry* for executables.
1825 (som_begin_writing): For executables, set the exec_entry and
1826 exec_flags fields.
1827 (som_copy_private_backend_section_data): Always return a value.
1828
1829 * libhppa.h (PA_PAGESIZE): Define.
1830
1831 * som.c (SOM_ALIGN): Define.
1832 (som_begin_writing): If writing an executable, initialize all
1833 fields in the exec header to zero. Update fields in the exec
1834 header as sizes of loadable subspaces are computed. Carefully
1835 preserve alignments when building executables. Actually write the
1836 exec after all the fields are filled in.
1837
1838 * Better long-filename handling. Reads SOM ABI compliant extended
1839 names, but doesn't quite write compliant extended names yet.
1840 * som.c (som_slurp_extended_name_table): Delete function. The
1841 generic code will handle things correctly.
1842 (som_slurp_armap): Seek to the beginning of the next member.
1843 (normalize): New function.
1844 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1845 name table into account when computing the file offsets in the
1846 SOM dictionary. Make sure to align to an even boundary.
1847 (som_write_armap): Initialize the checksum to zero.
1848 (ar_maxchars): Fix. Opps.
1849
1850 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1851
1852 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1853 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1854
1855 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1856
1857 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1858 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1859 * bfd-in2.h: Regenerated.
1860
1861 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1862 this was also named trad_unix_bfd_copy_private_bfd_data.
1863
1864 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1865
1866 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1867 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1868 returns NULL, it is not an error. It's possible that some of
1869 these checks are not necessary (because the size can never be
1870 zero), but putting in the checks is the conservative thing to do
1871 in light of the fact that some of these malloc calls replaced
1872 unchecked alloca calls, in which a zero argument would work fine.
1873
1874 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1875
1876 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1877 duplicate definition.
1878 (osf_core_bfd_is_local_label): Define.
1879
1880 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1881 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1882 failure indication, it merely means there are no relocs.
1883
1884 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1885 after NAME, since SunOS /bin/cc can't handle it.
1886
1887 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1888
1889 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1890 From sukes@glue.umd.edu (Tasuki Hirata).
1891
1892 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1893
1894 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1895 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1896 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1897
1898 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1899
1900 * som.c (som_prep_for_fixups): Detect section symbols based
1901 on either the lack of private data or the symbol flags. Do not
1902 munge section symbol names anymore -- they no longer confuse GDB.
1903 (som_begin_writing): Leave space for an exec header if writing
1904 an executable.
1905 (som_slurp_symbol_table): Recognize both forms of section symbol
1906 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1907 section symbols to be the name of the section they represent.
1908 Debugging symbols begin with "L$0\001", not just "L$".
1909
1910 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1911
1912 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1913
1914 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1915 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,

1934 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1935 Default new vectors for copying private backend data to bfd_true.
1936 Default new vector for determining if a symbol is a local label
1937 to bfd_generic_is_local_label.
1938
1939 * som.c (som_bfd_copy_private_section_data): New function.
1940 (som_bfd_is_local_label): New function.
1941 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1942
1943 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1944
1945 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1946
1947 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1948
1949 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1950
1951 * Most files:
1952 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1953 Indent some of them to GNU standards.
1954
1955 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1956 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

1958 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1959 Update copyright years.
1960
1961 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1962
1963 * som.c (som_prep_for_fixups): A relocation involving the section
1964 symbol for the *ABS* section is really a relocation involving
1965 no symbol.
1966 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1967 undefined symbols. Correctly distinguish between debugger symbols
1968 and section symbols.
1969
1970 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1971 for spaces and subspaces.
1972
1973 * som.c (som_bfd_count_ar_symbols): Fix typo.

1976 HAS_RELOC based on the object's magic number.
1977 (make_unique_section): Delete function. BFD and its users are
1978 prepared to handle multiple sections with the same name.
1979 (setup_sections): Allocate space on the BFD's obstack to hold
1980 section names. Use bfd_make_setion_anyway rather than the
1981 obsolete make_unique_section.

1983 on the BFD's flags.
1984 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

1996 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1997
1998 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info

2005
2006 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2007 cruft (like the #pragma alloca for AIX).
2008 In addition to that problem, the C alloca calls xmalloc, which
2009 means checking for being out of memory can't work right. The
2010 following changes remove all uses of alloca from BFD.
2011 * hosts/solaris2.h: Remove alloca cruft.
2012 * som.c: Replace alloca with a fixed size auto array.

2105 unused symbols argument.
2106
2107 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

2133 error code propogation working. Work on spacing and indention.
2134 Add FIXMEs for unresolved problems. Use enums rather than
2135 #defines for lots of things. Merge two functions which build
2136 linker stubs into a single function (so they can easily share a

2182 each case separately. Abort for bad errors until we get error
2183 code propogation working. Work on spacing and indention problems.

2347 * section.c (bfd_get_section_contents): Since this function reads
2348 unrelocated contents, the section's raw size is always the one to
2349 use for bounds checking.

2807 entry has type STY_LD change the x_scnlen into a pointer to a
2808 symbol and set fix_scnlen. Also, for a C_BSTAT symbol, change the
2809 value into a pointer to a symbol and set fix_value.
2810 * libcoff.h: Rebuilt.
2811 * coffgen.c (coff_mangle_symbols): Reindent. If fix_value is set,
2812 get the symbol offset. Likewise for fix_scnlen.

2818 (coff_write_symbols): Initialize debug_string_size to 0. If
2819 bfd_coff_symname_in_debug returns true, don't put symbol name in
2820 usual string table. After writing out all symbols, if

2822 .debug section.
2823 (coff_get_normalized_symtab): Clear new fix_value and fix_scnlen
2824 fields. If the string offset is 0, always use an empty string as
2825 the name.
2826 (coff_make_empty_symbol): Zero out the symbol structure.
2827 * reloc.c (bfd_perform_relocation): Work around one gross hack

2831 BFD_RELOC_PPC_BA26 and BFD_RELOC_PPC_TOC16.

2845 symbol has a value in the ECOFF symbol but not in the BFD symbol,
2846 keep the value in the ECOFF symbol. This helps gas.

2893
2894 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
2895 (only testing for m68k and vax at the moment); do verify that the

2910
2911 * hosts/vaxbsd.h (HOST_STACK_END_ADDR): Vax BSD doesn't define

2925
2926 * som.c, som.h (bfd_som_set_section_attributes,
2927 bfd_som_set_subsection_attributes): Change parameters from char

2939
2940 * archive.c (do_slurp_bsd_armap, bfd_slurp_bsd_armap_f2): Do not
2941 try to overlay the internal carsyms on the external symdefs. That
2942 can not work if the size of a host pointer is larger than 4 bytes.

3038 undefined, look it up in the linker hash table.
3039

3111 return value.
3112 * aoutf1.h (NAME(aout,sunos4_write_object_contents)): Don't write
3113 out dynamic symbols or relocs against reloc symbols, since they
3114 are already in the .text section and we wouldn't know where to
3115 write them anyhow.
3116 (sunos4_aout_backend): Initialize read_dynamic_symbols and
3117 read_dynamic_relocs fields.
3118 * aout-target.h (MY(backend_data)): Initialize

3310
3311 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
