2056 dynamicly linked executables.)
2058 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2061 * som.c (som_begin_writing): Fix braino (one call to align

2098 som_copyable_section_data_struct. Make the space and
2099 subspace dictionaries be pointers (to save space when
2100 only reading objects).
2102 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2103 some references changed. Allocate a copyable data stucture if
2104 none exists. Store info into the copyable data structure.

2106 (som_is_space, som_is_subspace, som_is_container): New functions.
2107 Use these instead of directly accessing private data.
2108 (som_prep_headers): Allocate space and subspace headers here.
2109 Fill in some fields in the space/subspace headers from the
2111 (som_bfd_copy_private_section_data): Only copy the stuff
2112 that we really need to make objcopy and strip work. Allocate
2113 the copy_data structure for the output bfd before copying.

2116 info that must be preserved when running objcopy/strip.

2118 macro. Add some comments on how the various fields are used.
2119 (som_section_data_struct): Make is_space and is_subspace bitfields.

2128 It is not used when only reading SOM objects.
2129 (som_prep_headers): Allocate space for and attach a file header
2130 to the output bfd. For executables, use the saved system_id
2131 value rather than trying to guess the right value. Do not abort
2132 wwhen setting file_hdr->entry* for executables.
2133 (som_begin_writing): For executables, set the exec_entry and
2135 (som_copy_private_backend_section_data): Always return a value.
2137 * libhppa.h (PA_PAGESIZE): Define.

2140 (som_begin_writing): If writing an executable, initialize all
2141 fields in the exec header to zero. Update fields in the exec
2142 header as sizes of loadable subspaces are computed. Carefully
2143 preserve alignments when building executables. Actually write the
2144 exec after all the fields are filled in.
2146 * Better long-filename handling. Reads SOM ABI compliant extended
2147 names, but doesn't quite write compliant extended names yet.
2148 * som.c (som_slurp_extended_name_table): Delete function. The
2149 generic code will handle things correctly.
2150 (som_slurp_armap): Seek to the beginning of the next member.
2151 (normalize): New function.
2152 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2153 name table into account when computing the file offsets in the
2154 SOM dictionary. Make sure to align to an even boundary.
2155 (som_write_armap): Initialize the checksum to zero.
2156 (ar_maxchars): Fix. Opps.

2174 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2175 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2176 returns NULL, it is not an error. It's possible that some of
2177 these checks are not necessary (because the size can never be
2178 zero), but putting in the checks is the conservative thing to do
2179 in light of the fact that some of these malloc calls replaced
2180 unchecked alloca calls, in which a zero argument would work fine.
2182 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2184 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2185 duplicate definition.

2188 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2189 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2190 failure indication, it merely means there are no relocs.
2192 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2193 after NAME, since SunOS /bin/cc can't handle it.
2195 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2197 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2198 From sukes@glue.umd.edu (Tasuki Hirata).
2200 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2202 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2203 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2204 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2206 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2208 * som.c (som_prep_for_fixups): Detect section symbols based
2209 on either the lack of private data or the symbol flags. Do not
2210 munge section symbol names anymore -- they no longer confuse GDB.
2211 (som_begin_writing): Leave space for an exec header if writing
2213 (som_slurp_symbol_table): Recognize both forms of section symbol
2214 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2215 section symbols to be the name of the section they represent.
2216 Debugging symbols begin with "L$0\001", not just "L$".

2242 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2243 Default new vectors for copying private backend data to bfd_true.

2245 to bfd_generic_is_local_label.
2247 * som.c (som_bfd_copy_private_section_data): New function.
2248 (som_bfd_is_local_label): New function.

2253 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2255 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2257 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2260 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2261 Indent some of them to GNU standards.
2263 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2264 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

2266 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2267 Update copyright years.
2269 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2271 * som.c (som_prep_for_fixups): A relocation involving the section
2272 symbol for the *ABS* section is really a relocation involving
2274 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2275 undefined symbols. Correctly distinguish between debugger symbols
2276 and section symbols.
2278 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2279 for spaces and subspaces.
2281 * som.c (som_bfd_count_ar_symbols): Fix typo.
2283 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2284 HAS_RELOC based on the object's magic number.
2285 (make_unique_section): Delete function. BFD and its users are
2286 prepared to handle multiple sections with the same name.
2287 (setup_sections): Allocate space on the BFD's obstack to hold
2288 section names. Use bfd_make_setion_anyway rather than the
2289 obsolete make_unique_section.

2312 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2314 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2315 cruft (like the #pragma alloca for AIX).
2316 In addition to that problem, the C alloca calls xmalloc, which
2317 means checking for being out of memory can't work right. The
2318 following changes remove all uses of alloca from BFD.
2319 * hosts/solaris2.h: Remove alloca cruft.
2320 * som.c: Replace alloca with a fixed size auto array.

2335 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2336 Elf*_Off typedefs by their expansion, the typedefs have been
2337 removed from include/elf/internal.h.
2338 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2339 SHT_PROGBITS section.

2358 * som.[ch]: Do not include libhppa.h in som.c, instead include
2361 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2362 include it in elf32-hppa.h.
2364 * som.c (log2): Return -1 on error rather than aborting.
2365 (setup_sections): Bubble up an error from log2.
2367 * Changes to make HP C compiler happy in both traditional
2369 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2371 (bfd_som_set_section_attributes): Use unsigned int rather than
2372 unsigned char to avoid GNU-C extensions.
2373 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2374 or failure rather than aborting on failure.
2376 * som.h (bfd_som_set_section_attributes): Fix prototype to match

2419 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2420 argument. Use the output symbols when canonicalizing the relocs,
2421 creating them if necessary.
2423 * linker.c (_bfd_generic_link_output_symbols): Do not
2424 rebuild/clobber the output symbols if they already exist.

2443 #defines for lots of things. Merge two functions which build
2444 linker stubs into a single function (so they can easily share a
2445 ton of common code).

2493 COMPLEX relocation support (it's never used anyway).
2494 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
2495 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
2496 (elf_hppa_tc_make_sections): Likewise.

2668 (b_out_relax_section): If a section contains no relocations, don't
2669 bother processing them.
2670 (b_out_get_relocated_section_contents): Set reloc_done. Assert

2674 that reloc->addend falls between the current source offset and the
2675 raw size of the input section.
2677 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
2678 bout. Default with no version number is still bout. Support

2698 * Finish basic read-write support for SOM archive libraries. Bugs
2699 surely remain as this hasn't been tested all that much.
2700 * som.c (SOM_LST_HASH_SIZE, SOM_LST_MODULE_LIMIT): Define.
2701 (struct som_misc_symbol_info): New structure to hold info necessary

3203 (only testing for m68k and vax at the moment); do verify that the
3204 preprocessor didn't trash the arch name inside the string version.

3235 bfd_som_set_subsection_attributes): Change parameters from char
3236 to int. Following a prototype with an old-style function definition

3343 use get_value to get the symbol value and check for undefined
3345 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
3346 undefined, look it up in the linker hash table.
3348 * aoutx.h (translate_symbol_table): The string index 0 has a

3373 The sparc (and possibly other?) NLM format requires a different
3374 way to write exports, so add a write_export field to the backend
3375 data (and set it to NULL for everything but the sparc).
