1987 from call to _bfd_generic_link_add_one_symbol.
1988 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1989 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR

2036 For executables, iterate through the sections to find out
2037 which contains the symbol's address rather than using the
2038 symbol_info field. (symbol_info has a different meaning for
2039 dynamicly linked executables.)
2041 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2044 * som.c (som_begin_writing): Fix braino (one call to align
2045 space/subspace data was done unconditionally rather than
2046 just for executables.)
2048 * som.c (som_begin_writing): Align text in all executables to
2049 make HPUX kernel happy. Fixes strip/objcopy for shared
2052 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2054 * som.c (som_begin_writing): Account for alignment needs of
2055 subspaces too when writing executables. Never request a negative
2056 bss size. Fixes some problems with demand paged executables,

2059 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2061 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not

2076 * som.h (som_copyable_section_data_struct): New structure
2077 containing all the private section information which needs
2078 to be copied from input section to output section during
2080 (som_section_data_struct): Remove several fields now in
2081 som_copyable_section_data_struct. Make the space and
2082 subspace dictionaries be pointers (to save space when
2083 only reading objects).
2085 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2086 some references changed. Allocate a copyable data stucture if
2087 none exists. Store info into the copyable data structure.
2088 (bfd_som_set_subsection_attributes): Likewise.
2089 (som_is_space, som_is_subspace, som_is_container): New functions.
2090 Use these instead of directly accessing private data.
2091 (som_prep_headers): Allocate space and subspace headers here.
2092 Fill in some fields in the space/subspace headers from the
2094 (som_bfd_copy_private_section_data): Only copy the stuff
2095 that we really need to make objcopy and strip work. Allocate
2096 the copy_data structure for the output bfd before copying.
2098 * som.h (struct som_exec_data): New structure to hold exec
2099 info that must be preserved when running objcopy/strip.
2100 (struct somdata): Add new "exec_data" field and accessor
2101 macro. Add some comments on how the various fields are used.
2102 (som_section_data_struct): Make is_space and is_subspace bitfields.
2103 Delete unused subspace_index. All references now use the
2104 target_index field within the section structure itself.
2106 * som.c (make_unique_section): Delete unused declaration.
2107 (som_bfd_copy_private_bfd_data): New function.
2108 (som_object_setup): Allocate space for and save exec information
2109 that needs to be copied during objcopy/strip.
2110 (som_mkobject): Do not allocate space for a file header here.
2111 It is not used when only reading SOM objects.
2112 (som_prep_headers): Allocate space for and attach a file header
2113 to the output bfd. For executables, use the saved system_id
2114 value rather than trying to guess the right value. Do not abort
2115 wwhen setting file_hdr->entry* for executables.
2116 (som_begin_writing): For executables, set the exec_entry and
2118 (som_copy_private_backend_section_data): Always return a value.
2120 * libhppa.h (PA_PAGESIZE): Define.
2122 * som.c (SOM_ALIGN): Define.
2123 (som_begin_writing): If writing an executable, initialize all
2124 fields in the exec header to zero. Update fields in the exec
2125 header as sizes of loadable subspaces are computed. Carefully
2126 preserve alignments when building executables. Actually write the
2127 exec after all the fields are filled in.
2129 * Better long-filename handling. Reads SOM ABI compliant extended
2130 names, but doesn't quite write compliant extended names yet.
2131 * som.c (som_slurp_extended_name_table): Delete function. The
2132 generic code will handle things correctly.
2133 (som_slurp_armap): Seek to the beginning of the next member.
2134 (normalize): New function.
2135 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2136 name table into account when computing the file offsets in the
2137 SOM dictionary. Make sure to align to an even boundary.
2138 (som_write_armap): Initialize the checksum to zero.
2139 (ar_maxchars): Fix. Opps.

2150 * bfd-in2.h: Regenerated.
2152 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2153 this was also named trad_unix_bfd_copy_private_bfd_data.
2155 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2157 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2158 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2159 returns NULL, it is not an error. It's possible that some of
2160 these checks are not necessary (because the size can never be
2161 zero), but putting in the checks is the conservative thing to do
2162 in light of the fact that some of these malloc calls replaced
2163 unchecked alloca calls, in which a zero argument would work fine.
2165 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

2172 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2173 failure indication, it merely means there are no relocs.
2175 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2176 after NAME, since SunOS /bin/cc can't handle it.
2178 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2180 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

2185 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2186 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2187 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2189 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2191 * som.c (som_prep_for_fixups): Detect section symbols based
2192 on either the lack of private data or the symbol flags. Do not
2193 munge section symbol names anymore -- they no longer confuse GDB.

2196 (som_slurp_symbol_table): Recognize both forms of section symbol
2197 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2198 section symbols to be the name of the section they represent.
2199 Debugging symbols begin with "L$0\001", not just "L$".

2254 * som.c (som_prep_for_fixups): A relocation involving the section
2255 symbol for the *ABS* section is really a relocation involving
2257 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2258 undefined symbols. Correctly distinguish between debugger symbols
2259 and section symbols.
2261 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2262 for spaces and subspaces.
2264 * som.c (som_bfd_count_ar_symbols): Fix typo.
2266 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2267 HAS_RELOC based on the object's magic number.
2268 (make_unique_section): Delete function. BFD and its users are
2269 prepared to handle multiple sections with the same name.
2270 (setup_sections): Allocate space on the BFD's obstack to hold
2271 section names. Use bfd_make_setion_anyway rather than the

2298 cruft (like the #pragma alloca for AIX).
2299 In addition to that problem, the C alloca calls xmalloc, which
2300 means checking for being out of memory can't work right. The
2301 following changes remove all uses of alloca from BFD.

2344 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2345 include it in elf32-hppa.h.
2347 * som.c (log2): Return -1 on error rather than aborting.
2348 (setup_sections): Bubble up an error from log2.
2350 * Changes to make HP C compiler happy in both traditional
2352 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

2355 unsigned char to avoid GNU-C extensions.
2356 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2357 or failure rather than aborting on failure.
2359 * som.h (bfd_som_set_section_attributes): Fix prototype to match

2636 Tue Feb 15 19:39:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2638 * section.c (bfd_get_section_contents): Since this function reads
2639 unrelocated contents, the section's raw size is always the one to
2640 use for bounds checking.

2643 link_order size field against cooked size, not raw size, of input
2646 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
2648 (aligncode): When shrinking, the addend should be set to the
2649 current offset in the section plus the number of bytes of padding
2650 that will actually be retained.
2651 (b_out_relax_section): If a section contains no relocations, don't
2652 bother processing them.
2653 (b_out_get_relocated_section_contents): Set reloc_done. Assert

2657 that reloc->addend falls between the current source offset and the
2658 raw size of the input section.
2660 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
2661 bout. Default with no version number is still bout. Support

3078 Fri Feb 4 23:55:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3080 Add basic support for writing RS/6000 XCOFF files.

3091 fields to bitfields. Added fields fix_value and fix_scnlen.
3092 (sec_to_styp_flags): If STYP_DEBUG is defined, use it rather than
3093 STYP_INFO for the type of a section named .debug.
3094 (coff_add_missing_symbols): Don't define if RS6000COFF_C.
3095 (coff_write_object_contents): If RS6000COFF_C, don't call

3098 entry has type STY_LD change the x_scnlen into a pointer to a
3099 symbol and set fix_scnlen. Also, for a C_BSTAT symbol, change the
3100 value into a pointer to a symbol and set fix_value.
3101 * libcoff.h: Rebuilt.

3115 fields. If the string offset is 0, always use an empty string as
3117 (coff_make_empty_symbol): Zero out the symbol structure.

3137 keep the value in the ECOFF symbol. This helps gas.
3139 * linker.c (_bfd_generic_link_output_symbols,
3140 _bfd_generic_link_write_global_symbol): Don't require that all
3141 references to a common symbol be themselves common symbols.

3181 new arguments to swap_aux functions.
3183 Sun Jan 30 15:14:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3185 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
3186 (only testing for m68k and vax at the moment); do verify that the
3187 preprocessor didn't trash the arch name inside the string version.

3217 * som.c, som.h (bfd_som_set_section_attributes,
3218 bfd_som_set_subsection_attributes): Change parameters from char
3219 to int. Following a prototype with an old-style function definition

3326 use get_value to get the symbol value and check for undefined
3328 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
3329 undefined, look it up in the linker hash table.
3331 * aoutx.h (translate_symbol_table): The string index 0 has a

3356 The sparc (and possibly other?) NLM format requires a different
3357 way to write exports, so add a write_export field to the backend
3358 data (and set it to NULL for everything but the sparc).
