1763 from undefined to section. Change handling of PC relative relocs:
1764 if against a section, they are correct in the object file, if
1765 against an external symbol they are pcrel_offset.

1893 extended name table.
1895 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1897 Support for link_order types which generate relocs in order to
1898 support -Ur in the linker.
1899 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1900 from call to _bfd_generic_link_add_one_symbol.
1901 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1902 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1903 instead of bitsize to add_to_set call back.
1904 (_bfd_generic_final_link): Account for link_order relocs when
1905 allocating space for relocations. Handle them in link_order loop.
1906 (_bfd_generic_reloc_link_order): New function.

1924 allocating space for relocations. Handle them in link_order loop.
1925 (ecoff_link_write_external): Set the storage class of a defined
1926 linker created symbol based on the section it is in. Correct
1927 bfd_link_hash_weak case to use .sc rather than .st.
1928 (ecoff_reloc_link_order): New function.
1929 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1931 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1937 bfd_zmalloc. Free a pointer, not a union.
1938 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1940 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1942 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1944 * som.c (bfd_section_from_som_symbol): Only to do the value
1945 comparison for function symbols within executables.
1947 * som.c (bfd_section_from_som_symbol): Renamed from
1948 som_section_from_subspace_index. Pass in a native SOM symbol.
1949 For executables, iterate through the sections to find out
1950 which contains the symbol's address rather than using the
1951 symbol_info field. (symbol_info has a different meaning for
1952 dynamicly linked executables.)
1954 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1957 * som.c (som_begin_writing): Fix braino (one call to align
1958 space/subspace data was done unconditionally rather than
1959 just for executables.)
1961 * som.c (som_begin_writing): Align text in all executables to
1962 make HPUX kernel happy. Fixes strip/objcopy for shared
1965 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1967 * som.c (som_begin_writing): Account for alignment needs of
1968 subspaces too when writing executables. Never request a negative
1969 bss size. Fixes some problems with demand paged executables,
1970 still having problems with pure executables and shared executables.
1972 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1974 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1975 bfd_zalloc for rawptr, because later on we may call free, not
1978 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1979 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1980 * cisco-core.c: New file.

1987 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1989 * som.h (som_copyable_section_data_struct): New structure
1990 containing all the private section information which needs
1991 to be copied from input section to output section during
1993 (som_section_data_struct): Remove several fields now in
1994 som_copyable_section_data_struct. Make the space and
1995 subspace dictionaries be pointers (to save space when
1996 only reading objects).
1998 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1999 some references changed. Allocate a copyable data stucture if
2000 none exists. Store info into the copyable data structure.
2001 (bfd_som_set_subsection_attributes): Likewise.
2002 (som_is_space, som_is_subspace, som_is_container): New functions.
2003 Use these instead of directly accessing private data.
2004 (som_prep_headers): Allocate space and subspace headers here.
2005 Fill in some fields in the space/subspace headers from the
2007 (som_bfd_copy_private_section_data): Only copy the stuff
2008 that we really need to make objcopy and strip work. Allocate
2009 the copy_data structure for the output bfd before copying.
2011 * som.h (struct som_exec_data): New structure to hold exec
2012 info that must be preserved when running objcopy/strip.
2013 (struct somdata): Add new "exec_data" field and accessor
2014 macro. Add some comments on how the various fields are used.
2015 (som_section_data_struct): Make is_space and is_subspace bitfields.
2016 Delete unused subspace_index. All references now use the
2017 target_index field within the section structure itself.
2019 * som.c (make_unique_section): Delete unused declaration.
2020 (som_bfd_copy_private_bfd_data): New function.
2021 (som_object_setup): Allocate space for and save exec information
2022 that needs to be copied during objcopy/strip.
2023 (som_mkobject): Do not allocate space for a file header here.
2024 It is not used when only reading SOM objects.
2025 (som_prep_headers): Allocate space for and attach a file header
2026 to the output bfd. For executables, use the saved system_id
2027 value rather than trying to guess the right value. Do not abort
2028 wwhen setting file_hdr->entry* for executables.
2029 (som_begin_writing): For executables, set the exec_entry and
2031 (som_copy_private_backend_section_data): Always return a value.
2033 * libhppa.h (PA_PAGESIZE): Define.
2035 * som.c (SOM_ALIGN): Define.
2036 (som_begin_writing): If writing an executable, initialize all
2037 fields in the exec header to zero. Update fields in the exec
2038 header as sizes of loadable subspaces are computed. Carefully
2039 preserve alignments when building executables. Actually write the
2040 exec after all the fields are filled in.
2042 * Better long-filename handling. Reads SOM ABI compliant extended
2043 names, but doesn't quite write compliant extended names yet.
2044 * som.c (som_slurp_extended_name_table): Delete function. The
2045 generic code will handle things correctly.
2046 (som_slurp_armap): Seek to the beginning of the next member.
2047 (normalize): New function.
2048 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2049 name table into account when computing the file offsets in the
2050 SOM dictionary. Make sure to align to an even boundary.
2051 (som_write_armap): Initialize the checksum to zero.
2052 (ar_maxchars): Fix. Opps.

2056 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2057 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2059 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2061 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2062 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2063 * bfd-in2.h: Regenerated.
2065 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2066 this was also named trad_unix_bfd_copy_private_bfd_data.
2068 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2070 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2071 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2072 returns NULL, it is not an error. It's possible that some of
2073 these checks are not necessary (because the size can never be
2074 zero), but putting in the checks is the conservative thing to do
2075 in light of the fact that some of these malloc calls replaced
2076 unchecked alloca calls, in which a zero argument would work fine.
2078 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2080 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2081 duplicate definition.
2082 (osf_core_bfd_is_local_label): Define.
2084 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2085 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2086 failure indication, it merely means there are no relocs.
2088 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2089 after NAME, since SunOS /bin/cc can't handle it.
2091 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2093 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2094 From sukes@glue.umd.edu (Tasuki Hirata).
2096 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2098 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2099 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2100 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2102 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2104 * som.c (som_prep_for_fixups): Detect section symbols based
2105 on either the lack of private data or the symbol flags. Do not
2106 munge section symbol names anymore -- they no longer confuse GDB.
2107 (som_begin_writing): Leave space for an exec header if writing
2109 (som_slurp_symbol_table): Recognize both forms of section symbol
2110 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2111 section symbols to be the name of the section they represent.
2112 Debugging symbols begin with "L$0\001", not just "L$".
2114 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2116 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2118 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2119 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2120 and bfd_is_local_label.
2122 * targets.c: Add new entries to the bfd_target structure.

2138 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2139 Default new vectors for copying private backend data to bfd_true.
2140 Default new vector for determining if a symbol is a local label
2141 to bfd_generic_is_local_label.
2143 * som.c (som_bfd_copy_private_section_data): New function.
2144 (som_bfd_is_local_label): New function.
2145 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2147 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2149 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2151 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2153 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2156 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2157 Indent some of them to GNU standards.
2159 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2160 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

2162 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2163 Update copyright years.
2165 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2167 * som.c (som_prep_for_fixups): A relocation involving the section
2168 symbol for the *ABS* section is really a relocation involving
2170 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2171 undefined symbols. Correctly distinguish between debugger symbols
2172 and section symbols.
2174 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2175 for spaces and subspaces.

2211 cruft (like the #pragma alloca for AIX).
2212 In addition to that problem, the C alloca calls xmalloc, which

3269 The sparc (and possibly other?) NLM format requires a different
3270 way to write exports, so add a write_export field to the backend
3271 data (and set it to NULL for everything but the sparc).

4407 * elfcode.h (elf_object_p): Rather than looking through an array
4408 of architectures, get the ELF EM_xxx code from the backend
4409 information. Let the generic ELF target match any EM_xxx code not
