3995 from undefined to section. Change handling of PC relative relocs:
3996 if against a section, they are correct in the object file, if
3997 against an external symbol they are pcrel_offset.

4130 support -Ur in the linker.
4131 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4132 from call to _bfd_generic_link_add_one_symbol.
4133 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4134 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4135 instead of bitsize to add_to_set call back.
4136 (_bfd_generic_final_link): Account for link_order relocs when
4137 allocating space for relocations. Handle them in link_order loop.

4181 For executables, iterate through the sections to find out
4182 which contains the symbol's address rather than using the
4183 symbol_info field. (symbol_info has a different meaning for
4184 dynamicly linked executables.)
4186 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4189 * som.c (som_begin_writing): Fix braino (one call to align
4190 space/subspace data was done unconditionally rather than
4191 just for executables.)
4193 * som.c (som_begin_writing): Align text in all executables to
4194 make HPUX kernel happy. Fixes strip/objcopy for shared
4197 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4199 * som.c (som_begin_writing): Account for alignment needs of
4200 subspaces too when writing executables. Never request a negative
4201 bss size. Fixes some problems with demand paged executables,
4202 still having problems with pure executables and shared executables.
4204 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4206 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not

4221 * som.h (som_copyable_section_data_struct): New structure
4222 containing all the private section information which needs
4223 to be copied from input section to output section during
4225 (som_section_data_struct): Remove several fields now in
4226 som_copyable_section_data_struct. Make the space and
4227 subspace dictionaries be pointers (to save space when
4228 only reading objects).
4230 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4231 some references changed. Allocate a copyable data stucture if
4232 none exists. Store info into the copyable data structure.
4233 (bfd_som_set_subsection_attributes): Likewise.
4234 (som_is_space, som_is_subspace, som_is_container): New functions.
4235 Use these instead of directly accessing private data.
4236 (som_prep_headers): Allocate space and subspace headers here.
4237 Fill in some fields in the space/subspace headers from the
4239 (som_bfd_copy_private_section_data): Only copy the stuff
4240 that we really need to make objcopy and strip work. Allocate
4241 the copy_data structure for the output bfd before copying.
4243 * som.h (struct som_exec_data): New structure to hold exec
4244 info that must be preserved when running objcopy/strip.
4245 (struct somdata): Add new "exec_data" field and accessor
4246 macro. Add some comments on how the various fields are used.
4247 (som_section_data_struct): Make is_space and is_subspace bitfields.
4248 Delete unused subspace_index. All references now use the
4249 target_index field within the section structure itself.
4251 * som.c (make_unique_section): Delete unused declaration.
4252 (som_bfd_copy_private_bfd_data): New function.
4253 (som_object_setup): Allocate space for and save exec information
4254 that needs to be copied during objcopy/strip.
4255 (som_mkobject): Do not allocate space for a file header here.
4256 It is not used when only reading SOM objects.
4257 (som_prep_headers): Allocate space for and attach a file header
4258 to the output bfd. For executables, use the saved system_id
4259 value rather than trying to guess the right value. Do not abort
4260 wwhen setting file_hdr->entry* for executables.
4261 (som_begin_writing): For executables, set the exec_entry and
4263 (som_copy_private_backend_section_data): Always return a value.
4265 * libhppa.h (PA_PAGESIZE): Define.
4267 * som.c (SOM_ALIGN): Define.
4268 (som_begin_writing): If writing an executable, initialize all
4269 fields in the exec header to zero. Update fields in the exec
4270 header as sizes of loadable subspaces are computed. Carefully
4271 preserve alignments when building executables. Actually write the
4272 exec after all the fields are filled in.
4274 * Better long-filename handling. Reads SOM ABI compliant extended
4275 names, but doesn't quite write compliant extended names yet.
4276 * som.c (som_slurp_extended_name_table): Delete function. The
4277 generic code will handle things correctly.
4278 (som_slurp_armap): Seek to the beginning of the next member.
4279 (normalize): New function.
4280 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4281 name table into account when computing the file offsets in the
4282 SOM dictionary. Make sure to align to an even boundary.
4283 (som_write_armap): Initialize the checksum to zero.
4284 (ar_maxchars): Fix. Opps.
4286 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4288 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4289 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4291 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

4294 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4295 * bfd-in2.h: Regenerated.
4297 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4298 this was also named trad_unix_bfd_copy_private_bfd_data.
4300 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4302 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4303 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4304 returns NULL, it is not an error. It's possible that some of
4305 these checks are not necessary (because the size can never be
4306 zero), but putting in the checks is the conservative thing to do
4307 in light of the fact that some of these malloc calls replaced
4308 unchecked alloca calls, in which a zero argument would work fine.
4310 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4312 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove

4316 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4317 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4318 failure indication, it merely means there are no relocs.
4320 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4321 after NAME, since SunOS /bin/cc can't handle it.
4323 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4325 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

4330 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4331 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4332 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4334 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4336 * som.c (som_prep_for_fixups): Detect section symbols based
4337 on either the lack of private data or the symbol flags. Do not
4338 munge section symbol names anymore -- they no longer confuse GDB.

4341 (som_slurp_symbol_table): Recognize both forms of section symbol
4342 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4343 section symbols to be the name of the section they represent.
4344 Debugging symbols begin with "L$0\001", not just "L$".

4399 * som.c (som_prep_for_fixups): A relocation involving the section
4400 symbol for the *ABS* section is really a relocation involving
4402 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4403 undefined symbols. Correctly distinguish between debugger symbols
4404 and section symbols.

4407 for spaces and subspaces.
4409 * som.c (som_bfd_count_ar_symbols): Fix typo.

4443 cruft (like the #pragma alloca for AIX).
4444 In addition to that problem, the C alloca calls xmalloc, which
4445 means checking for being out of memory can't work right. The
4446 following changes remove all uses of alloca from BFD.

4490 include it in elf32-hppa.h.
4492 * som.c (log2): Return -1 on error rather than aborting.
4493 (setup_sections): Bubble up an error from log2.
4495 * Changes to make HP C compiler happy in both traditional
4497 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

4502 or failure rather than aborting on failure.
4504 * som.h (bfd_som_set_section_attributes): Fix prototype to match

4547 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4548 argument. Use the output symbols when canonicalizing the relocs,
4549 creating them if necessary.
4551 * linker.c (_bfd_generic_link_output_symbols): Do not
4552 rebuild/clobber the output symbols if they already exist.

4781 Tue Feb 15 19:39:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4783 * section.c (bfd_get_section_contents): Since this function reads
4784 unrelocated contents, the section's raw size is always the one to
4785 use for bounds checking.
4787 * linker.c (default_indirect_link_order): In assertion, compare
4788 link_order size field against cooked size, not raw size, of input
4791 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
4793 (aligncode): When shrinking, the addend should be set to the
4794 current offset in the section plus the number of bytes of padding
4795 that will actually be retained.
4796 (b_out_relax_section): If a section contains no relocations, don't
4797 bother processing them.
4798 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4802 that reloc->addend falls between the current source offset and the
4803 raw size of the input section.
4805 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
4806 bout. Default with no version number is still bout. Support

5331 (only testing for m68k and vax at the moment); do verify that the
5332 preprocessor didn't trash the arch name inside the string version.

5363 bfd_som_set_subsection_attributes): Change parameters from char
5364 to int. Following a prototype with an old-style function definition

5471 use get_value to get the symbol value and check for undefined
5473 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5474 undefined, look it up in the linker hash table.
5476 * aoutx.h (translate_symbol_table): The string index 0 has a

5501 The sparc (and possibly other?) NLM format requires a different
5502 way to write exports, so add a write_export field to the backend
5503 data (and set it to NULL for everything but the sparc).
