1784 required by expansions. Set s and unset h when converting a reloc
1785 from undefined to section. Change handling of PC relative relocs:
1786 if against a section, they are correct in the object file, if
1787 against an external symbol they are pcrel_offset.
1788 (mips_relax_section): New function.
1789 (mips_relax_pcrel16): New function.
1790 (ecoff_bfd_relax_section): Define.

1875 reloc, used in embedded PIC code.
1876 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

1884 add_symbls entry point.
1886 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1887 counting relocs. Set SEC_RELOC flag for any section which has

1915 extended name table.
1917 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1919 Support for link_order types which generate relocs in order to
1920 support -Ur in the linker.
1921 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1922 from call to _bfd_generic_link_add_one_symbol.
1923 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1924 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1925 instead of bitsize to add_to_set call back.
1926 (_bfd_generic_final_link): Account for link_order relocs when
1927 allocating space for relocations. Handle them in link_order loop.
1928 (_bfd_generic_reloc_link_order): New function.

1945 (ecoff_bfd_final_link): Account for link_order relocs when
1946 allocating space for relocations. Handle them in link_order loop.
1947 (ecoff_link_write_external): Set the storage class of a defined
1948 linker created symbol based on the section it is in. Correct
1949 bfd_link_hash_weak case to use .sc rather than .st.
1950 (ecoff_reloc_link_order): New function.
1951 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1953 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1959 bfd_zmalloc. Free a pointer, not a union.
1960 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1962 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1964 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1966 * som.c (bfd_section_from_som_symbol): Only to do the value
1967 comparison for function symbols within executables.
1969 * som.c (bfd_section_from_som_symbol): Renamed from
1970 som_section_from_subspace_index. Pass in a native SOM symbol.
1971 For executables, iterate through the sections to find out
1972 which contains the symbol's address rather than using the
1973 symbol_info field. (symbol_info has a different meaning for
1974 dynamicly linked executables.)
1976 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1979 * som.c (som_begin_writing): Fix braino (one call to align
1980 space/subspace data was done unconditionally rather than
1981 just for executables.)
1983 * som.c (som_begin_writing): Align text in all executables to
1984 make HPUX kernel happy. Fixes strip/objcopy for shared
1987 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1989 * som.c (som_begin_writing): Account for alignment needs of
1990 subspaces too when writing executables. Never request a negative
1991 bss size. Fixes some problems with demand paged executables,
1992 still having problems with pure executables and shared executables.
1994 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1996 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1997 bfd_zalloc for rawptr, because later on we may call free, not
2000 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2001 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2002 * cisco-core.c: New file.

2004 * configure.in: Recognize cisco_core_vec.
2005 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2006 * targets.c: Add cisco_core_vec.
2007 * bfd-in2.h: Rebuilt.
2009 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2011 * som.h (som_copyable_section_data_struct): New structure
2012 containing all the private section information which needs
2013 to be copied from input section to output section during
2015 (som_section_data_struct): Remove several fields now in
2016 som_copyable_section_data_struct. Make the space and
2017 subspace dictionaries be pointers (to save space when
2018 only reading objects).
2020 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2021 some references changed. Allocate a copyable data stucture if
2022 none exists. Store info into the copyable data structure.
2023 (bfd_som_set_subsection_attributes): Likewise.
2024 (som_is_space, som_is_subspace, som_is_container): New functions.
2025 Use these instead of directly accessing private data.
2026 (som_prep_headers): Allocate space and subspace headers here.
2027 Fill in some fields in the space/subspace headers from the
2029 (som_bfd_copy_private_section_data): Only copy the stuff
2030 that we really need to make objcopy and strip work. Allocate
2031 the copy_data structure for the output bfd before copying.
2033 * som.h (struct som_exec_data): New structure to hold exec
2034 info that must be preserved when running objcopy/strip.
2035 (struct somdata): Add new "exec_data" field and accessor
2036 macro. Add some comments on how the various fields are used.
2037 (som_section_data_struct): Make is_space and is_subspace bitfields.
2038 Delete unused subspace_index. All references now use the
2039 target_index field within the section structure itself.
2041 * som.c (make_unique_section): Delete unused declaration.
2042 (som_bfd_copy_private_bfd_data): New function.
2043 (som_object_setup): Allocate space for and save exec information
2044 that needs to be copied during objcopy/strip.
2045 (som_mkobject): Do not allocate space for a file header here.
2046 It is not used when only reading SOM objects.
2047 (som_prep_headers): Allocate space for and attach a file header
2048 to the output bfd. For executables, use the saved system_id
2049 value rather than trying to guess the right value. Do not abort
2050 wwhen setting file_hdr->entry* for executables.
2051 (som_begin_writing): For executables, set the exec_entry and
2053 (som_copy_private_backend_section_data): Always return a value.
2055 * libhppa.h (PA_PAGESIZE): Define.
2057 * som.c (SOM_ALIGN): Define.
2058 (som_begin_writing): If writing an executable, initialize all
2059 fields in the exec header to zero. Update fields in the exec
2060 header as sizes of loadable subspaces are computed. Carefully
2061 preserve alignments when building executables. Actually write the
2062 exec after all the fields are filled in.
2064 * Better long-filename handling. Reads SOM ABI compliant extended
2065 names, but doesn't quite write compliant extended names yet.
2066 * som.c (som_slurp_extended_name_table): Delete function. The
2067 generic code will handle things correctly.
2068 (som_slurp_armap): Seek to the beginning of the next member.
2069 (normalize): New function.
2070 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2071 name table into account when computing the file offsets in the
2072 SOM dictionary. Make sure to align to an even boundary.
2073 (som_write_armap): Initialize the checksum to zero.
2074 (ar_maxchars): Fix. Opps.

2078 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2079 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2081 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2083 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2084 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2085 * bfd-in2.h: Regenerated.
2087 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2088 this was also named trad_unix_bfd_copy_private_bfd_data.
2090 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2092 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2093 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2094 returns NULL, it is not an error. It's possible that some of
2095 these checks are not necessary (because the size can never be
2096 zero), but putting in the checks is the conservative thing to do
2097 in light of the fact that some of these malloc calls replaced
2098 unchecked alloca calls, in which a zero argument would work fine.
2100 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2102 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2103 duplicate definition.
2104 (osf_core_bfd_is_local_label): Define.
2106 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2107 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2108 failure indication, it merely means there are no relocs.
2110 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2111 after NAME, since SunOS /bin/cc can't handle it.
2113 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2115 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2116 From sukes@glue.umd.edu (Tasuki Hirata).
2118 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2120 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2121 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2122 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2124 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2126 * som.c (som_prep_for_fixups): Detect section symbols based
2127 on either the lack of private data or the symbol flags. Do not
2128 munge section symbol names anymore -- they no longer confuse GDB.
2129 (som_begin_writing): Leave space for an exec header if writing
2131 (som_slurp_symbol_table): Recognize both forms of section symbol
2132 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2133 section symbols to be the name of the section they represent.
2134 Debugging symbols begin with "L$0\001", not just "L$".
2136 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2138 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2140 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2141 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2142 and bfd_is_local_label.
2144 * targets.c: Add new entries to the bfd_target structure.
2146 * bfd.c (bfd_copy_private_bfd_data): New definition.

2157 the target vector which all point to bfd_false.
2159 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2160 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2161 Default new vectors for copying private backend data to bfd_true.
2162 Default new vector for determining if a symbol is a local label
2163 to bfd_generic_is_local_label.
2165 * som.c (som_bfd_copy_private_section_data): New function.
2166 (som_bfd_is_local_label): New function.
2167 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2169 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2171 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

2233 cruft (like the #pragma alloca for AIX).
2234 In addition to that problem, the C alloca calls xmalloc, which

3291 The sparc (and possibly other?) NLM format requires a different
3292 way to write exports, so add a write_export field to the backend
3293 data (and set it to NULL for everything but the sparc).
