1756 * som.c (som_begin_writing): New approach at dealing with holes
1757 in executables left by the HP linker. Does not rely on subspace
1758 alignments as subspaces are *NOT* guaranteed to be properly

1810 from undefined to section. Change handling of PC relative relocs:
1811 if against a section, they are correct in the object file, if
1812 against an external symbol they are pcrel_offset.
1813 (mips_relax_section): New function.
1814 (mips_relax_pcrel16): New function.

1909 add_symbls entry point.
1911 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1912 counting relocs. Set SEC_RELOC flag for any section which has

1940 extended name table.
1942 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1944 Support for link_order types which generate relocs in order to
1945 support -Ur in the linker.
1946 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1947 from call to _bfd_generic_link_add_one_symbol.
1948 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1949 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1950 instead of bitsize to add_to_set call back.
1951 (_bfd_generic_final_link): Account for link_order relocs when
1952 allocating space for relocations. Handle them in link_order loop.
1953 (_bfd_generic_reloc_link_order): New function.

1971 allocating space for relocations. Handle them in link_order loop.
1972 (ecoff_link_write_external): Set the storage class of a defined
1973 linker created symbol based on the section it is in. Correct
1974 bfd_link_hash_weak case to use .sc rather than .st.
1975 (ecoff_reloc_link_order): New function.
1976 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1978 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1984 bfd_zmalloc. Free a pointer, not a union.
1985 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1987 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1989 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1991 * som.c (bfd_section_from_som_symbol): Only to do the value
1992 comparison for function symbols within executables.
1994 * som.c (bfd_section_from_som_symbol): Renamed from
1995 som_section_from_subspace_index. Pass in a native SOM symbol.
1996 For executables, iterate through the sections to find out
1997 which contains the symbol's address rather than using the
1998 symbol_info field. (symbol_info has a different meaning for
1999 dynamicly linked executables.)
2001 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2004 * som.c (som_begin_writing): Fix braino (one call to align
2005 space/subspace data was done unconditionally rather than
2006 just for executables.)
2008 * som.c (som_begin_writing): Align text in all executables to
2009 make HPUX kernel happy. Fixes strip/objcopy for shared
2012 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2014 * som.c (som_begin_writing): Account for alignment needs of
2015 subspaces too when writing executables. Never request a negative
2016 bss size. Fixes some problems with demand paged executables,
2017 still having problems with pure executables and shared executables.
2019 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2021 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2022 bfd_zalloc for rawptr, because later on we may call free, not
2025 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2026 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2027 * cisco-core.c: New file.

2029 * configure.in: Recognize cisco_core_vec.
2030 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2031 * targets.c: Add cisco_core_vec.
2032 * bfd-in2.h: Rebuilt.
2034 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2036 * som.h (som_copyable_section_data_struct): New structure
2037 containing all the private section information which needs
2038 to be copied from input section to output section during
2040 (som_section_data_struct): Remove several fields now in
2041 som_copyable_section_data_struct. Make the space and
2042 subspace dictionaries be pointers (to save space when
2043 only reading objects).
2045 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2046 some references changed. Allocate a copyable data stucture if
2047 none exists. Store info into the copyable data structure.
2048 (bfd_som_set_subsection_attributes): Likewise.
2049 (som_is_space, som_is_subspace, som_is_container): New functions.
2050 Use these instead of directly accessing private data.
2051 (som_prep_headers): Allocate space and subspace headers here.
2052 Fill in some fields in the space/subspace headers from the
2054 (som_bfd_copy_private_section_data): Only copy the stuff
2055 that we really need to make objcopy and strip work. Allocate
2056 the copy_data structure for the output bfd before copying.
2058 * som.h (struct som_exec_data): New structure to hold exec
2059 info that must be preserved when running objcopy/strip.
2060 (struct somdata): Add new "exec_data" field and accessor
2061 macro. Add some comments on how the various fields are used.
2062 (som_section_data_struct): Make is_space and is_subspace bitfields.
2063 Delete unused subspace_index. All references now use the
2064 target_index field within the section structure itself.
2066 * som.c (make_unique_section): Delete unused declaration.
2067 (som_bfd_copy_private_bfd_data): New function.
2068 (som_object_setup): Allocate space for and save exec information
2069 that needs to be copied during objcopy/strip.
2070 (som_mkobject): Do not allocate space for a file header here.
2071 It is not used when only reading SOM objects.
2072 (som_prep_headers): Allocate space for and attach a file header
2073 to the output bfd. For executables, use the saved system_id
2074 value rather than trying to guess the right value. Do not abort
2075 wwhen setting file_hdr->entry* for executables.
2076 (som_begin_writing): For executables, set the exec_entry and
2078 (som_copy_private_backend_section_data): Always return a value.
2080 * libhppa.h (PA_PAGESIZE): Define.
2082 * som.c (SOM_ALIGN): Define.
2083 (som_begin_writing): If writing an executable, initialize all
2084 fields in the exec header to zero. Update fields in the exec
2085 header as sizes of loadable subspaces are computed. Carefully
2086 preserve alignments when building executables. Actually write the
2087 exec after all the fields are filled in.
2089 * Better long-filename handling. Reads SOM ABI compliant extended
2090 names, but doesn't quite write compliant extended names yet.
2091 * som.c (som_slurp_extended_name_table): Delete function. The
2092 generic code will handle things correctly.
2093 (som_slurp_armap): Seek to the beginning of the next member.
2094 (normalize): New function.
2095 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2096 name table into account when computing the file offsets in the
2097 SOM dictionary. Make sure to align to an even boundary.
2098 (som_write_armap): Initialize the checksum to zero.
2099 (ar_maxchars): Fix. Opps.
2101 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2103 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2104 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2106 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2108 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2109 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2110 * bfd-in2.h: Regenerated.
2112 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2113 this was also named trad_unix_bfd_copy_private_bfd_data.
2115 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2117 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2118 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2119 returns NULL, it is not an error. It's possible that some of
2120 these checks are not necessary (because the size can never be
2121 zero), but putting in the checks is the conservative thing to do
2122 in light of the fact that some of these malloc calls replaced
2123 unchecked alloca calls, in which a zero argument would work fine.
2125 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2127 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2128 duplicate definition.
2129 (osf_core_bfd_is_local_label): Define.
2131 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2132 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2133 failure indication, it merely means there are no relocs.
2135 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2136 after NAME, since SunOS /bin/cc can't handle it.
2138 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2140 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2141 From sukes@glue.umd.edu (Tasuki Hirata).
2143 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2145 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2146 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2147 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2149 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2151 * som.c (som_prep_for_fixups): Detect section symbols based
2152 on either the lack of private data or the symbol flags. Do not
2153 munge section symbol names anymore -- they no longer confuse GDB.
2154 (som_begin_writing): Leave space for an exec header if writing
2156 (som_slurp_symbol_table): Recognize both forms of section symbol
2157 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2158 section symbols to be the name of the section they represent.
2159 Debugging symbols begin with "L$0\001", not just "L$".
2161 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2163 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2165 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2166 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2167 and bfd_is_local_label.
2169 * targets.c: Add new entries to the bfd_target structure.
2171 * bfd.c (bfd_copy_private_bfd_data): New definition.

2258 cruft (like the #pragma alloca for AIX).
2259 In addition to that problem, the C alloca calls xmalloc, which

3178 bfd_som_set_subsection_attributes): Change parameters from char

3289 undefined, look it up in the linker hash table.
3291 * aoutx.h (translate_symbol_table): The string index 0 has a

3316 The sparc (and possibly other?) NLM format requires a different
3317 way to write exports, so add a write_export field to the backend
3318 data (and set it to NULL for everything but the sparc).
