1770 in executables left by the HP linker. Does not rely on subspace
1771 alignments as subspaces are *NOT* guaranteed to be properly

1822 required by expansions. Set s and unset h when converting a reloc
1823 from undefined to section. Change handling of PC relative relocs:
1824 if against a section, they are correct in the object file, if
1825 against an external symbol they are pcrel_offset.
1826 (mips_relax_section): New function.
1827 (mips_relax_pcrel16): New function.
1828 (ecoff_bfd_relax_section): Define.

1922 add_symbls entry point.
1924 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before

1953 extended name table.
1955 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1957 Support for link_order types which generate relocs in order to
1958 support -Ur in the linker.
1959 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1960 from call to _bfd_generic_link_add_one_symbol.
1961 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1962 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1963 instead of bitsize to add_to_set call back.
1964 (_bfd_generic_final_link): Account for link_order relocs when
1965 allocating space for relocations. Handle them in link_order loop.
1966 (_bfd_generic_reloc_link_order): New function.

1984 allocating space for relocations. Handle them in link_order loop.
1985 (ecoff_link_write_external): Set the storage class of a defined
1986 linker created symbol based on the section it is in. Correct
1987 bfd_link_hash_weak case to use .sc rather than .st.
1988 (ecoff_reloc_link_order): New function.
1989 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

1998 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2000 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2002 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2004 * som.c (bfd_section_from_som_symbol): Only to do the value
2005 comparison for function symbols within executables.
2007 * som.c (bfd_section_from_som_symbol): Renamed from
2008 som_section_from_subspace_index. Pass in a native SOM symbol.
2009 For executables, iterate through the sections to find out
2010 which contains the symbol's address rather than using the
2011 symbol_info field. (symbol_info has a different meaning for
2012 dynamicly linked executables.)
2014 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2017 * som.c (som_begin_writing): Fix braino (one call to align
2018 space/subspace data was done unconditionally rather than
2019 just for executables.)
2021 * som.c (som_begin_writing): Align text in all executables to
2022 make HPUX kernel happy. Fixes strip/objcopy for shared
2025 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2027 * som.c (som_begin_writing): Account for alignment needs of
2028 subspaces too when writing executables. Never request a negative
2029 bss size. Fixes some problems with demand paged executables,
2030 still having problems with pure executables and shared executables.
2032 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2034 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2035 bfd_zalloc for rawptr, because later on we may call free, not
2038 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2039 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2040 * cisco-core.c: New file.

2047 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2049 * som.h (som_copyable_section_data_struct): New structure
2050 containing all the private section information which needs
2051 to be copied from input section to output section during
2053 (som_section_data_struct): Remove several fields now in
2054 som_copyable_section_data_struct. Make the space and
2055 subspace dictionaries be pointers (to save space when
2056 only reading objects).
2058 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2059 some references changed. Allocate a copyable data stucture if
2060 none exists. Store info into the copyable data structure.
2061 (bfd_som_set_subsection_attributes): Likewise.
2062 (som_is_space, som_is_subspace, som_is_container): New functions.
2063 Use these instead of directly accessing private data.
2064 (som_prep_headers): Allocate space and subspace headers here.
2065 Fill in some fields in the space/subspace headers from the
2067 (som_bfd_copy_private_section_data): Only copy the stuff
2068 that we really need to make objcopy and strip work. Allocate
2069 the copy_data structure for the output bfd before copying.
2071 * som.h (struct som_exec_data): New structure to hold exec
2072 info that must be preserved when running objcopy/strip.
2073 (struct somdata): Add new "exec_data" field and accessor
2074 macro. Add some comments on how the various fields are used.
2075 (som_section_data_struct): Make is_space and is_subspace bitfields.
2076 Delete unused subspace_index. All references now use the
2077 target_index field within the section structure itself.
2079 * som.c (make_unique_section): Delete unused declaration.
2080 (som_bfd_copy_private_bfd_data): New function.
2081 (som_object_setup): Allocate space for and save exec information
2082 that needs to be copied during objcopy/strip.
2083 (som_mkobject): Do not allocate space for a file header here.
2084 It is not used when only reading SOM objects.
2085 (som_prep_headers): Allocate space for and attach a file header
2086 to the output bfd. For executables, use the saved system_id
2087 value rather than trying to guess the right value. Do not abort
2088 wwhen setting file_hdr->entry* for executables.
2089 (som_begin_writing): For executables, set the exec_entry and
2091 (som_copy_private_backend_section_data): Always return a value.
2093 * libhppa.h (PA_PAGESIZE): Define.
2095 * som.c (SOM_ALIGN): Define.
2096 (som_begin_writing): If writing an executable, initialize all
2097 fields in the exec header to zero. Update fields in the exec
2098 header as sizes of loadable subspaces are computed. Carefully
2099 preserve alignments when building executables. Actually write the
2100 exec after all the fields are filled in.
2102 * Better long-filename handling. Reads SOM ABI compliant extended
2103 names, but doesn't quite write compliant extended names yet.
2104 * som.c (som_slurp_extended_name_table): Delete function. The
2105 generic code will handle things correctly.
2106 (som_slurp_armap): Seek to the beginning of the next member.
2107 (normalize): New function.
2108 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2109 name table into account when computing the file offsets in the
2110 SOM dictionary. Make sure to align to an even boundary.
2111 (som_write_armap): Initialize the checksum to zero.
2112 (ar_maxchars): Fix. Opps.
2114 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2116 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2117 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2119 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2121 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2122 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2123 * bfd-in2.h: Regenerated.
2125 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2126 this was also named trad_unix_bfd_copy_private_bfd_data.
2128 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2130 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2131 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2132 returns NULL, it is not an error. It's possible that some of
2133 these checks are not necessary (because the size can never be
2134 zero), but putting in the checks is the conservative thing to do
2135 in light of the fact that some of these malloc calls replaced
2136 unchecked alloca calls, in which a zero argument would work fine.
2138 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2140 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2141 duplicate definition.
2142 (osf_core_bfd_is_local_label): Define.
2144 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2145 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2146 failure indication, it merely means there are no relocs.
2148 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2149 after NAME, since SunOS /bin/cc can't handle it.
2151 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2153 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2154 From sukes@glue.umd.edu (Tasuki Hirata).
2156 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2158 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2159 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2160 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2162 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2164 * som.c (som_prep_for_fixups): Detect section symbols based
2165 on either the lack of private data or the symbol flags. Do not
2166 munge section symbol names anymore -- they no longer confuse GDB.
2167 (som_begin_writing): Leave space for an exec header if writing
2169 (som_slurp_symbol_table): Recognize both forms of section symbol
2170 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2171 section symbols to be the name of the section they represent.
2172 Debugging symbols begin with "L$0\001", not just "L$".

3191 bfd_som_set_subsection_attributes): Change parameters from char
3192 to int. Following a prototype with an old-style function definition

3302 undefined, look it up in the linker hash table.
3304 * aoutx.h (translate_symbol_table): The string index 0 has a

3329 The sparc (and possibly other?) NLM format requires a different
3330 way to write exports, so add a write_export field to the backend
3331 data (and set it to NULL for everything but the sparc).
