1740 * som.c (som_begin_writing): New approach at dealing with holes
1741 in executables left by the HP linker. Does not rely on subspace
1742 alignments as subspaces are *NOT* guaranteed to be properly
1743 aligned in an executable (can you believe that!).
1745 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1747 * som.c (som_get_section_contents): New function. Do not try

1793 required by expansions. Set s and unset h when converting a reloc
1794 from undefined to section. Change handling of PC relative relocs:
1795 if against a section, they are correct in the object file, if
1796 against an external symbol they are pcrel_offset.
1797 (mips_relax_section): New function.
1798 (mips_relax_pcrel16): New function.

1884 reloc, used in embedded PIC code.
1885 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

1893 add_symbls entry point.
1895 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1896 counting relocs. Set SEC_RELOC flag for any section which has

1924 extended name table.
1926 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1928 Support for link_order types which generate relocs in order to
1929 support -Ur in the linker.
1930 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1931 from call to _bfd_generic_link_add_one_symbol.
1932 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1933 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1934 instead of bitsize to add_to_set call back.
1935 (_bfd_generic_final_link): Account for link_order relocs when
1936 allocating space for relocations. Handle them in link_order loop.
1937 (_bfd_generic_reloc_link_order): New function.

1955 allocating space for relocations. Handle them in link_order loop.
1956 (ecoff_link_write_external): Set the storage class of a defined
1957 linker created symbol based on the section it is in. Correct
1958 bfd_link_hash_weak case to use .sc rather than .st.
1959 (ecoff_reloc_link_order): New function.
1960 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1962 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1968 bfd_zmalloc. Free a pointer, not a union.
1969 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1971 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1973 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1975 * som.c (bfd_section_from_som_symbol): Only to do the value
1976 comparison for function symbols within executables.
1978 * som.c (bfd_section_from_som_symbol): Renamed from
1979 som_section_from_subspace_index. Pass in a native SOM symbol.
1980 For executables, iterate through the sections to find out
1981 which contains the symbol's address rather than using the
1982 symbol_info field. (symbol_info has a different meaning for
1983 dynamicly linked executables.)
1985 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1988 * som.c (som_begin_writing): Fix braino (one call to align
1989 space/subspace data was done unconditionally rather than
1990 just for executables.)
1992 * som.c (som_begin_writing): Align text in all executables to
1993 make HPUX kernel happy. Fixes strip/objcopy for shared
1996 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1998 * som.c (som_begin_writing): Account for alignment needs of
1999 subspaces too when writing executables. Never request a negative
2000 bss size. Fixes some problems with demand paged executables,
2001 still having problems with pure executables and shared executables.
2003 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2005 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2006 bfd_zalloc for rawptr, because later on we may call free, not
2009 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2010 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2011 * cisco-core.c: New file.

2013 * configure.in: Recognize cisco_core_vec.
2014 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2015 * targets.c: Add cisco_core_vec.
2016 * bfd-in2.h: Rebuilt.
2018 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2020 * som.h (som_copyable_section_data_struct): New structure
2021 containing all the private section information which needs
2022 to be copied from input section to output section during
2024 (som_section_data_struct): Remove several fields now in
2025 som_copyable_section_data_struct. Make the space and
2026 subspace dictionaries be pointers (to save space when
2027 only reading objects).
2029 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2030 some references changed. Allocate a copyable data stucture if
2031 none exists. Store info into the copyable data structure.
2032 (bfd_som_set_subsection_attributes): Likewise.
2033 (som_is_space, som_is_subspace, som_is_container): New functions.
2034 Use these instead of directly accessing private data.
2035 (som_prep_headers): Allocate space and subspace headers here.
2036 Fill in some fields in the space/subspace headers from the
2038 (som_bfd_copy_private_section_data): Only copy the stuff
2039 that we really need to make objcopy and strip work. Allocate
2040 the copy_data structure for the output bfd before copying.
2042 * som.h (struct som_exec_data): New structure to hold exec
2043 info that must be preserved when running objcopy/strip.
2044 (struct somdata): Add new "exec_data" field and accessor
2045 macro. Add some comments on how the various fields are used.
2046 (som_section_data_struct): Make is_space and is_subspace bitfields.
2047 Delete unused subspace_index. All references now use the
2048 target_index field within the section structure itself.
2050 * som.c (make_unique_section): Delete unused declaration.
2051 (som_bfd_copy_private_bfd_data): New function.
2052 (som_object_setup): Allocate space for and save exec information
2053 that needs to be copied during objcopy/strip.
2054 (som_mkobject): Do not allocate space for a file header here.
2055 It is not used when only reading SOM objects.
2056 (som_prep_headers): Allocate space for and attach a file header
2057 to the output bfd. For executables, use the saved system_id
2058 value rather than trying to guess the right value. Do not abort
2059 wwhen setting file_hdr->entry* for executables.
2060 (som_begin_writing): For executables, set the exec_entry and
2062 (som_copy_private_backend_section_data): Always return a value.
2064 * libhppa.h (PA_PAGESIZE): Define.
2066 * som.c (SOM_ALIGN): Define.
2067 (som_begin_writing): If writing an executable, initialize all
2068 fields in the exec header to zero. Update fields in the exec
2069 header as sizes of loadable subspaces are computed. Carefully
2070 preserve alignments when building executables. Actually write the
2071 exec after all the fields are filled in.
2073 * Better long-filename handling. Reads SOM ABI compliant extended
2074 names, but doesn't quite write compliant extended names yet.
2075 * som.c (som_slurp_extended_name_table): Delete function. The
2076 generic code will handle things correctly.
2077 (som_slurp_armap): Seek to the beginning of the next member.
2078 (normalize): New function.
2079 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2080 name table into account when computing the file offsets in the
2081 SOM dictionary. Make sure to align to an even boundary.
2082 (som_write_armap): Initialize the checksum to zero.
2083 (ar_maxchars): Fix. Opps.

2087 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2088 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2090 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2092 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2093 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2094 * bfd-in2.h: Regenerated.
2096 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2097 this was also named trad_unix_bfd_copy_private_bfd_data.
2099 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2101 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2102 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2103 returns NULL, it is not an error. It's possible that some of
2104 these checks are not necessary (because the size can never be
2105 zero), but putting in the checks is the conservative thing to do
2106 in light of the fact that some of these malloc calls replaced
2107 unchecked alloca calls, in which a zero argument would work fine.
2109 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2111 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2112 duplicate definition.
2113 (osf_core_bfd_is_local_label): Define.
2115 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2116 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2117 failure indication, it merely means there are no relocs.
2119 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2120 after NAME, since SunOS /bin/cc can't handle it.
2122 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2124 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2125 From sukes@glue.umd.edu (Tasuki Hirata).
2127 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2129 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2130 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2131 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2133 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2135 * som.c (som_prep_for_fixups): Detect section symbols based
2136 on either the lack of private data or the symbol flags. Do not
2137 munge section symbol names anymore -- they no longer confuse GDB.
2138 (som_begin_writing): Leave space for an exec header if writing
2140 (som_slurp_symbol_table): Recognize both forms of section symbol
2141 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2142 section symbols to be the name of the section they represent.
2143 Debugging symbols begin with "L$0\001", not just "L$".
2145 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2147 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2149 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2150 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2151 and bfd_is_local_label.
2153 * targets.c: Add new entries to the bfd_target structure.

2169 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2170 Default new vectors for copying private backend data to bfd_true.
2171 Default new vector for determining if a symbol is a local label
2172 to bfd_generic_is_local_label.
2174 * som.c (som_bfd_copy_private_section_data): New function.

2242 cruft (like the #pragma alloca for AIX).
2243 In addition to that problem, the C alloca calls xmalloc, which

3273 undefined, look it up in the linker hash table.
3275 * aoutx.h (translate_symbol_table): The string index 0 has a

3300 The sparc (and possibly other?) NLM format requires a different
3301 way to write exports, so add a write_export field to the backend
3302 data (and set it to NULL for everything but the sparc).
