1771 from undefined to section. Change handling of PC relative relocs:
1772 if against a section, they are correct in the object file, if
1773 against an external symbol they are pcrel_offset.

1901 extended name table.
1903 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1905 Support for link_order types which generate relocs in order to
1906 support -Ur in the linker.
1907 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1908 from call to _bfd_generic_link_add_one_symbol.
1909 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1910 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1911 instead of bitsize to add_to_set call back.
1912 (_bfd_generic_final_link): Account for link_order relocs when
1913 allocating space for relocations. Handle them in link_order loop.
1914 (_bfd_generic_reloc_link_order): New function.

1932 allocating space for relocations. Handle them in link_order loop.
1933 (ecoff_link_write_external): Set the storage class of a defined
1934 linker created symbol based on the section it is in. Correct
1935 bfd_link_hash_weak case to use .sc rather than .st.
1936 (ecoff_reloc_link_order): New function.
1937 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1939 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1945 bfd_zmalloc. Free a pointer, not a union.
1946 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1948 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1950 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1952 * som.c (bfd_section_from_som_symbol): Only to do the value
1953 comparison for function symbols within executables.
1955 * som.c (bfd_section_from_som_symbol): Renamed from
1956 som_section_from_subspace_index. Pass in a native SOM symbol.
1957 For executables, iterate through the sections to find out
1958 which contains the symbol's address rather than using the
1959 symbol_info field. (symbol_info has a different meaning for
1960 dynamicly linked executables.)
1962 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1965 * som.c (som_begin_writing): Fix braino (one call to align
1966 space/subspace data was done unconditionally rather than
1967 just for executables.)
1969 * som.c (som_begin_writing): Align text in all executables to
1970 make HPUX kernel happy. Fixes strip/objcopy for shared
1973 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1975 * som.c (som_begin_writing): Account for alignment needs of
1976 subspaces too when writing executables. Never request a negative
1977 bss size. Fixes some problems with demand paged executables,
1978 still having problems with pure executables and shared executables.
1980 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1982 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1983 bfd_zalloc for rawptr, because later on we may call free, not
1986 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1987 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1988 * cisco-core.c: New file.

1990 * configure.in: Recognize cisco_core_vec.
1991 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.

1995 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1997 * som.h (som_copyable_section_data_struct): New structure
1998 containing all the private section information which needs
1999 to be copied from input section to output section during
2001 (som_section_data_struct): Remove several fields now in
2002 som_copyable_section_data_struct. Make the space and
2003 subspace dictionaries be pointers (to save space when
2004 only reading objects).
2006 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2007 some references changed. Allocate a copyable data stucture if
2008 none exists. Store info into the copyable data structure.
2009 (bfd_som_set_subsection_attributes): Likewise.
2010 (som_is_space, som_is_subspace, som_is_container): New functions.
2011 Use these instead of directly accessing private data.
2012 (som_prep_headers): Allocate space and subspace headers here.
2013 Fill in some fields in the space/subspace headers from the
2015 (som_bfd_copy_private_section_data): Only copy the stuff
2016 that we really need to make objcopy and strip work. Allocate
2017 the copy_data structure for the output bfd before copying.
2019 * som.h (struct som_exec_data): New structure to hold exec
2020 info that must be preserved when running objcopy/strip.
2021 (struct somdata): Add new "exec_data" field and accessor
2022 macro. Add some comments on how the various fields are used.
2023 (som_section_data_struct): Make is_space and is_subspace bitfields.
2024 Delete unused subspace_index. All references now use the
2025 target_index field within the section structure itself.
2027 * som.c (make_unique_section): Delete unused declaration.
2028 (som_bfd_copy_private_bfd_data): New function.
2029 (som_object_setup): Allocate space for and save exec information
2030 that needs to be copied during objcopy/strip.
2031 (som_mkobject): Do not allocate space for a file header here.
2032 It is not used when only reading SOM objects.
2033 (som_prep_headers): Allocate space for and attach a file header
2034 to the output bfd. For executables, use the saved system_id
2035 value rather than trying to guess the right value. Do not abort
2036 wwhen setting file_hdr->entry* for executables.
2037 (som_begin_writing): For executables, set the exec_entry and
2039 (som_copy_private_backend_section_data): Always return a value.
2041 * libhppa.h (PA_PAGESIZE): Define.
2043 * som.c (SOM_ALIGN): Define.
2044 (som_begin_writing): If writing an executable, initialize all
2045 fields in the exec header to zero. Update fields in the exec
2046 header as sizes of loadable subspaces are computed. Carefully
2047 preserve alignments when building executables. Actually write the
2048 exec after all the fields are filled in.
2050 * Better long-filename handling. Reads SOM ABI compliant extended
2051 names, but doesn't quite write compliant extended names yet.
2052 * som.c (som_slurp_extended_name_table): Delete function. The
2053 generic code will handle things correctly.
2054 (som_slurp_armap): Seek to the beginning of the next member.
2055 (normalize): New function.
2056 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2057 name table into account when computing the file offsets in the
2058 SOM dictionary. Make sure to align to an even boundary.
2059 (som_write_armap): Initialize the checksum to zero.
2060 (ar_maxchars): Fix. Opps.
2062 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2064 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2065 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2067 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2069 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2070 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2071 * bfd-in2.h: Regenerated.
2073 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2074 this was also named trad_unix_bfd_copy_private_bfd_data.
2076 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2078 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2079 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2080 returns NULL, it is not an error. It's possible that some of
2081 these checks are not necessary (because the size can never be
2082 zero), but putting in the checks is the conservative thing to do
2083 in light of the fact that some of these malloc calls replaced
2084 unchecked alloca calls, in which a zero argument would work fine.
2086 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2088 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2089 duplicate definition.
2090 (osf_core_bfd_is_local_label): Define.
2092 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2093 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2094 failure indication, it merely means there are no relocs.
2096 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2097 after NAME, since SunOS /bin/cc can't handle it.
2099 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2101 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2102 From sukes@glue.umd.edu (Tasuki Hirata).
2104 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2106 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2107 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2108 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2110 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2112 * som.c (som_prep_for_fixups): Detect section symbols based
2113 on either the lack of private data or the symbol flags. Do not
2114 munge section symbol names anymore -- they no longer confuse GDB.
2115 (som_begin_writing): Leave space for an exec header if writing
2117 (som_slurp_symbol_table): Recognize both forms of section symbol
2118 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2119 section symbols to be the name of the section they represent.
2120 Debugging symbols begin with "L$0\001", not just "L$".
2122 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2124 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2126 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2127 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2128 and bfd_is_local_label.
2130 * targets.c: Add new entries to the bfd_target structure.

2143 the target vector which all point to bfd_false.
2145 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2146 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2147 Default new vectors for copying private backend data to bfd_true.
2148 Default new vector for determining if a symbol is a local label
2149 to bfd_generic_is_local_label.
2151 * som.c (som_bfd_copy_private_section_data): New function.
2152 (som_bfd_is_local_label): New function.
2153 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2155 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2157 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2159 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2161 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2164 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2165 Indent some of them to GNU standards.
2167 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2168 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

2170 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2171 Update copyright years.

2219 cruft (like the #pragma alloca for AIX).
2220 In addition to that problem, the C alloca calls xmalloc, which

3277 The sparc (and possibly other?) NLM format requires a different
3278 way to write exports, so add a write_export field to the backend
3279 data (and set it to NULL for everything but the sparc).
