1747 * som.c (som_begin_writing): New approach at dealing with holes
1748 in executables left by the HP linker. Does not rely on subspace
1749 alignments as subspaces are *NOT* guaranteed to be properly
1750 aligned in an executable (can you believe that!).
1752 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1754 * som.c (som_get_section_contents): New function. Do not try

1800 required by expansions. Set s and unset h when converting a reloc
1801 from undefined to section. Change handling of PC relative relocs:
1802 if against a section, they are correct in the object file, if
1803 against an external symbol they are pcrel_offset.
1804 (mips_relax_section): New function.
1805 (mips_relax_pcrel16): New function.
1806 (ecoff_bfd_relax_section): Define.

1899 link_order loop. Use _bfd_generic_link_add_symbols_collect for
1900 add_symbls entry point.
1902 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1903 counting relocs. Set SEC_RELOC flag for any section which has

1931 extended name table.
1933 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1935 Support for link_order types which generate relocs in order to
1936 support -Ur in the linker.
1937 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1938 from call to _bfd_generic_link_add_one_symbol.
1939 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1940 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1941 instead of bitsize to add_to_set call back.
1942 (_bfd_generic_final_link): Account for link_order relocs when
1943 allocating space for relocations. Handle them in link_order loop.
1944 (_bfd_generic_reloc_link_order): New function.

1962 allocating space for relocations. Handle them in link_order loop.
1963 (ecoff_link_write_external): Set the storage class of a defined
1964 linker created symbol based on the section it is in. Correct
1965 bfd_link_hash_weak case to use .sc rather than .st.
1966 (ecoff_reloc_link_order): New function.
1967 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

1975 bfd_zmalloc. Free a pointer, not a union.
1976 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1978 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1980 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1982 * som.c (bfd_section_from_som_symbol): Only to do the value
1983 comparison for function symbols within executables.
1985 * som.c (bfd_section_from_som_symbol): Renamed from
1986 som_section_from_subspace_index. Pass in a native SOM symbol.
1987 For executables, iterate through the sections to find out
1988 which contains the symbol's address rather than using the
1989 symbol_info field. (symbol_info has a different meaning for
1990 dynamicly linked executables.)
1992 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1995 * som.c (som_begin_writing): Fix braino (one call to align
1996 space/subspace data was done unconditionally rather than
1997 just for executables.)
1999 * som.c (som_begin_writing): Align text in all executables to
2000 make HPUX kernel happy. Fixes strip/objcopy for shared
2003 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2005 * som.c (som_begin_writing): Account for alignment needs of
2006 subspaces too when writing executables. Never request a negative
2007 bss size. Fixes some problems with demand paged executables,
2008 still having problems with pure executables and shared executables.
2010 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2012 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2013 bfd_zalloc for rawptr, because later on we may call free, not
2016 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2017 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2018 * cisco-core.c: New file.

2020 * configure.in: Recognize cisco_core_vec.
2021 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2022 * targets.c: Add cisco_core_vec.
2023 * bfd-in2.h: Rebuilt.
2025 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2027 * som.h (som_copyable_section_data_struct): New structure
2028 containing all the private section information which needs
2029 to be copied from input section to output section during
2031 (som_section_data_struct): Remove several fields now in
2032 som_copyable_section_data_struct. Make the space and
2033 subspace dictionaries be pointers (to save space when
2034 only reading objects).
2036 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2037 some references changed. Allocate a copyable data stucture if
2038 none exists. Store info into the copyable data structure.
2039 (bfd_som_set_subsection_attributes): Likewise.
2040 (som_is_space, som_is_subspace, som_is_container): New functions.
2041 Use these instead of directly accessing private data.
2042 (som_prep_headers): Allocate space and subspace headers here.
2043 Fill in some fields in the space/subspace headers from the
2045 (som_bfd_copy_private_section_data): Only copy the stuff
2046 that we really need to make objcopy and strip work. Allocate
2047 the copy_data structure for the output bfd before copying.
2049 * som.h (struct som_exec_data): New structure to hold exec
2050 info that must be preserved when running objcopy/strip.
2051 (struct somdata): Add new "exec_data" field and accessor
2052 macro. Add some comments on how the various fields are used.
2053 (som_section_data_struct): Make is_space and is_subspace bitfields.
2054 Delete unused subspace_index. All references now use the
2055 target_index field within the section structure itself.
2057 * som.c (make_unique_section): Delete unused declaration.
2058 (som_bfd_copy_private_bfd_data): New function.
2059 (som_object_setup): Allocate space for and save exec information
2060 that needs to be copied during objcopy/strip.
2061 (som_mkobject): Do not allocate space for a file header here.
2062 It is not used when only reading SOM objects.
2063 (som_prep_headers): Allocate space for and attach a file header
2064 to the output bfd. For executables, use the saved system_id
2065 value rather than trying to guess the right value. Do not abort
2066 wwhen setting file_hdr->entry* for executables.
2067 (som_begin_writing): For executables, set the exec_entry and
2069 (som_copy_private_backend_section_data): Always return a value.
2071 * libhppa.h (PA_PAGESIZE): Define.
2073 * som.c (SOM_ALIGN): Define.
2074 (som_begin_writing): If writing an executable, initialize all
2075 fields in the exec header to zero. Update fields in the exec
2076 header as sizes of loadable subspaces are computed. Carefully
2077 preserve alignments when building executables. Actually write the
2078 exec after all the fields are filled in.
2080 * Better long-filename handling. Reads SOM ABI compliant extended
2081 names, but doesn't quite write compliant extended names yet.
2082 * som.c (som_slurp_extended_name_table): Delete function. The
2083 generic code will handle things correctly.
2084 (som_slurp_armap): Seek to the beginning of the next member.
2085 (normalize): New function.
2086 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2087 name table into account when computing the file offsets in the
2088 SOM dictionary. Make sure to align to an even boundary.
2089 (som_write_armap): Initialize the checksum to zero.
2090 (ar_maxchars): Fix. Opps.
2092 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2094 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2095 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2097 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2099 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2100 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2101 * bfd-in2.h: Regenerated.
2103 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2104 this was also named trad_unix_bfd_copy_private_bfd_data.
2106 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2108 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2109 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2110 returns NULL, it is not an error. It's possible that some of
2111 these checks are not necessary (because the size can never be
2112 zero), but putting in the checks is the conservative thing to do
2113 in light of the fact that some of these malloc calls replaced
2114 unchecked alloca calls, in which a zero argument would work fine.
2116 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2118 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2119 duplicate definition.
2120 (osf_core_bfd_is_local_label): Define.
2122 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2123 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2124 failure indication, it merely means there are no relocs.
2126 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2127 after NAME, since SunOS /bin/cc can't handle it.
2129 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2131 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2132 From sukes@glue.umd.edu (Tasuki Hirata).
2134 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2136 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2137 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2138 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2140 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2142 * som.c (som_prep_for_fixups): Detect section symbols based
2143 on either the lack of private data or the symbol flags. Do not
2144 munge section symbol names anymore -- they no longer confuse GDB.
2145 (som_begin_writing): Leave space for an exec header if writing
2147 (som_slurp_symbol_table): Recognize both forms of section symbol
2148 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2149 section symbols to be the name of the section they represent.
2150 Debugging symbols begin with "L$0\001", not just "L$".
2152 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2154 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2156 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2157 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2158 and bfd_is_local_label.
2160 * targets.c: Add new entries to the bfd_target structure.

2173 the target vector which all point to bfd_false.
2175 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c

3280 undefined, look it up in the linker hash table.
3282 * aoutx.h (translate_symbol_table): The string index 0 has a

3307 The sparc (and possibly other?) NLM format requires a different
3308 way to write exports, so add a write_export field to the backend
3309 data (and set it to NULL for everything but the sparc).
