1781 required by expansions. Set s and unset h when converting a reloc
1782 from undefined to section. Change handling of PC relative relocs:
1783 if against a section, they are correct in the object file, if
1784 against an external symbol they are pcrel_offset.
1785 (mips_relax_section): New function.
1786 (mips_relax_pcrel16): New function.
1787 (ecoff_bfd_relax_section): Define.

1872 reloc, used in embedded PIC code.
1873 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

1912 extended name table.
1914 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1916 Support for link_order types which generate relocs in order to
1917 support -Ur in the linker.
1918 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1919 from call to _bfd_generic_link_add_one_symbol.
1920 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1921 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1922 instead of bitsize to add_to_set call back.
1923 (_bfd_generic_final_link): Account for link_order relocs when
1924 allocating space for relocations. Handle them in link_order loop.
1925 (_bfd_generic_reloc_link_order): New function.

1943 allocating space for relocations. Handle them in link_order loop.
1944 (ecoff_link_write_external): Set the storage class of a defined
1945 linker created symbol based on the section it is in. Correct
1946 bfd_link_hash_weak case to use .sc rather than .st.
1947 (ecoff_reloc_link_order): New function.
1948 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1950 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1955 * cisco-core.c (cisco_core_file_p): Only pass one argument to
1956 bfd_zmalloc. Free a pointer, not a union.
1957 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1959 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1961 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1963 * som.c (bfd_section_from_som_symbol): Only to do the value
1964 comparison for function symbols within executables.
1966 * som.c (bfd_section_from_som_symbol): Renamed from
1967 som_section_from_subspace_index. Pass in a native SOM symbol.
1968 For executables, iterate through the sections to find out
1969 which contains the symbol's address rather than using the
1970 symbol_info field. (symbol_info has a different meaning for
1971 dynamicly linked executables.)
1973 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1976 * som.c (som_begin_writing): Fix braino (one call to align
1977 space/subspace data was done unconditionally rather than
1978 just for executables.)
1980 * som.c (som_begin_writing): Align text in all executables to
1981 make HPUX kernel happy. Fixes strip/objcopy for shared
1984 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1986 * som.c (som_begin_writing): Account for alignment needs of
1987 subspaces too when writing executables. Never request a negative
1988 bss size. Fixes some problems with demand paged executables,
1989 still having problems with pure executables and shared executables.
1991 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1993 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1994 bfd_zalloc for rawptr, because later on we may call free, not
1997 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1998 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1999 * cisco-core.c: New file.

2001 * configure.in: Recognize cisco_core_vec.
2002 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2003 * targets.c: Add cisco_core_vec.

2006 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2008 * som.h (som_copyable_section_data_struct): New structure
2009 containing all the private section information which needs
2010 to be copied from input section to output section during
2012 (som_section_data_struct): Remove several fields now in
2013 som_copyable_section_data_struct. Make the space and
2014 subspace dictionaries be pointers (to save space when
2015 only reading objects).
2017 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2018 some references changed. Allocate a copyable data stucture if
2019 none exists. Store info into the copyable data structure.
2020 (bfd_som_set_subsection_attributes): Likewise.
2021 (som_is_space, som_is_subspace, som_is_container): New functions.
2022 Use these instead of directly accessing private data.
2023 (som_prep_headers): Allocate space and subspace headers here.
2024 Fill in some fields in the space/subspace headers from the
2026 (som_bfd_copy_private_section_data): Only copy the stuff
2027 that we really need to make objcopy and strip work. Allocate
2028 the copy_data structure for the output bfd before copying.
2030 * som.h (struct som_exec_data): New structure to hold exec
2031 info that must be preserved when running objcopy/strip.
2032 (struct somdata): Add new "exec_data" field and accessor
2033 macro. Add some comments on how the various fields are used.
2034 (som_section_data_struct): Make is_space and is_subspace bitfields.
2035 Delete unused subspace_index. All references now use the
2036 target_index field within the section structure itself.
2038 * som.c (make_unique_section): Delete unused declaration.
2039 (som_bfd_copy_private_bfd_data): New function.
2040 (som_object_setup): Allocate space for and save exec information
2041 that needs to be copied during objcopy/strip.
2042 (som_mkobject): Do not allocate space for a file header here.
2043 It is not used when only reading SOM objects.
2044 (som_prep_headers): Allocate space for and attach a file header
2045 to the output bfd. For executables, use the saved system_id
2046 value rather than trying to guess the right value. Do not abort
2047 wwhen setting file_hdr->entry* for executables.
2048 (som_begin_writing): For executables, set the exec_entry and
2050 (som_copy_private_backend_section_data): Always return a value.
2052 * libhppa.h (PA_PAGESIZE): Define.
2054 * som.c (SOM_ALIGN): Define.
2055 (som_begin_writing): If writing an executable, initialize all
2056 fields in the exec header to zero. Update fields in the exec
2057 header as sizes of loadable subspaces are computed. Carefully
2058 preserve alignments when building executables. Actually write the
2059 exec after all the fields are filled in.
2061 * Better long-filename handling. Reads SOM ABI compliant extended
2062 names, but doesn't quite write compliant extended names yet.
2063 * som.c (som_slurp_extended_name_table): Delete function. The
2064 generic code will handle things correctly.
2065 (som_slurp_armap): Seek to the beginning of the next member.
2066 (normalize): New function.
2067 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2068 name table into account when computing the file offsets in the
2069 SOM dictionary. Make sure to align to an even boundary.
2070 (som_write_armap): Initialize the checksum to zero.
2071 (ar_maxchars): Fix. Opps.

2075 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2076 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2078 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2080 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2081 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2082 * bfd-in2.h: Regenerated.
2084 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2085 this was also named trad_unix_bfd_copy_private_bfd_data.
2087 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2089 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2090 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2091 returns NULL, it is not an error. It's possible that some of
2092 these checks are not necessary (because the size can never be
2093 zero), but putting in the checks is the conservative thing to do
2094 in light of the fact that some of these malloc calls replaced
2095 unchecked alloca calls, in which a zero argument would work fine.
2097 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2099 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2100 duplicate definition.
2101 (osf_core_bfd_is_local_label): Define.
2103 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2104 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2105 failure indication, it merely means there are no relocs.
2107 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2108 after NAME, since SunOS /bin/cc can't handle it.
2110 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2112 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2113 From sukes@glue.umd.edu (Tasuki Hirata).
2115 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2117 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2118 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2119 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2121 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2123 * som.c (som_prep_for_fixups): Detect section symbols based
2124 on either the lack of private data or the symbol flags. Do not
2125 munge section symbol names anymore -- they no longer confuse GDB.
2126 (som_begin_writing): Leave space for an exec header if writing
2128 (som_slurp_symbol_table): Recognize both forms of section symbol
2129 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2130 section symbols to be the name of the section they represent.
2131 Debugging symbols begin with "L$0\001", not just "L$".
2133 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2135 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2137 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2138 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2139 and bfd_is_local_label.
2141 * targets.c: Add new entries to the bfd_target structure.
2143 * bfd.c (bfd_copy_private_bfd_data): New definition.

2154 the target vector which all point to bfd_false.
2156 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2157 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2158 Default new vectors for copying private backend data to bfd_true.
2159 Default new vector for determining if a symbol is a local label
2160 to bfd_generic_is_local_label.
2162 * som.c (som_bfd_copy_private_section_data): New function.
2163 (som_bfd_is_local_label): New function.
2164 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2166 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2168 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2170 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.

2230 cruft (like the #pragma alloca for AIX).
2231 In addition to that problem, the C alloca calls xmalloc, which
