3985 from undefined to section. Change handling of PC relative relocs:
3986 if against a section, they are correct in the object file, if
3987 against an external symbol they are pcrel_offset.

4120 support -Ur in the linker.
4121 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4122 from call to _bfd_generic_link_add_one_symbol.
4123 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4124 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4125 instead of bitsize to add_to_set call back.
4126 (_bfd_generic_final_link): Account for link_order relocs when
4127 allocating space for relocations. Handle them in link_order loop.

4167 comparison for function symbols within executables.
4169 * som.c (bfd_section_from_som_symbol): Renamed from
4170 som_section_from_subspace_index. Pass in a native SOM symbol.
4171 For executables, iterate through the sections to find out
4172 which contains the symbol's address rather than using the
4173 symbol_info field. (symbol_info has a different meaning for
4174 dynamicly linked executables.)
4176 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4179 * som.c (som_begin_writing): Fix braino (one call to align
4180 space/subspace data was done unconditionally rather than
4181 just for executables.)
4183 * som.c (som_begin_writing): Align text in all executables to
4184 make HPUX kernel happy. Fixes strip/objcopy for shared
4187 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4189 * som.c (som_begin_writing): Account for alignment needs of
4190 subspaces too when writing executables. Never request a negative
4191 bss size. Fixes some problems with demand paged executables,
4192 still having problems with pure executables and shared executables.
4194 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4196 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4197 bfd_zalloc for rawptr, because later on we may call free, not
4200 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4201 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.

4211 * som.h (som_copyable_section_data_struct): New structure
4212 containing all the private section information which needs
4213 to be copied from input section to output section during
4215 (som_section_data_struct): Remove several fields now in
4216 som_copyable_section_data_struct. Make the space and
4217 subspace dictionaries be pointers (to save space when
4218 only reading objects).
4220 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4221 some references changed. Allocate a copyable data stucture if
4222 none exists. Store info into the copyable data structure.
4223 (bfd_som_set_subsection_attributes): Likewise.
4224 (som_is_space, som_is_subspace, som_is_container): New functions.
4225 Use these instead of directly accessing private data.
4226 (som_prep_headers): Allocate space and subspace headers here.
4227 Fill in some fields in the space/subspace headers from the
4229 (som_bfd_copy_private_section_data): Only copy the stuff
4230 that we really need to make objcopy and strip work. Allocate
4231 the copy_data structure for the output bfd before copying.
4233 * som.h (struct som_exec_data): New structure to hold exec
4234 info that must be preserved when running objcopy/strip.
4235 (struct somdata): Add new "exec_data" field and accessor
4236 macro. Add some comments on how the various fields are used.
4237 (som_section_data_struct): Make is_space and is_subspace bitfields.
4238 Delete unused subspace_index. All references now use the
4239 target_index field within the section structure itself.
4241 * som.c (make_unique_section): Delete unused declaration.
4242 (som_bfd_copy_private_bfd_data): New function.
4243 (som_object_setup): Allocate space for and save exec information
4244 that needs to be copied during objcopy/strip.
4245 (som_mkobject): Do not allocate space for a file header here.
4246 It is not used when only reading SOM objects.
4247 (som_prep_headers): Allocate space for and attach a file header
4248 to the output bfd. For executables, use the saved system_id
4249 value rather than trying to guess the right value. Do not abort
4250 wwhen setting file_hdr->entry* for executables.
4251 (som_begin_writing): For executables, set the exec_entry and
4253 (som_copy_private_backend_section_data): Always return a value.
4255 * libhppa.h (PA_PAGESIZE): Define.
4257 * som.c (SOM_ALIGN): Define.
4258 (som_begin_writing): If writing an executable, initialize all
4259 fields in the exec header to zero. Update fields in the exec
4260 header as sizes of loadable subspaces are computed. Carefully
4261 preserve alignments when building executables. Actually write the
4262 exec after all the fields are filled in.
4264 * Better long-filename handling. Reads SOM ABI compliant extended
4265 names, but doesn't quite write compliant extended names yet.
4266 * som.c (som_slurp_extended_name_table): Delete function. The
4267 generic code will handle things correctly.
4268 (som_slurp_armap): Seek to the beginning of the next member.
4269 (normalize): New function.
4270 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4271 name table into account when computing the file offsets in the
4272 SOM dictionary. Make sure to align to an even boundary.
4273 (som_write_armap): Initialize the checksum to zero.
4274 (ar_maxchars): Fix. Opps.
4276 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4278 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4279 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4281 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4283 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4284 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4285 * bfd-in2.h: Regenerated.
4287 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4288 this was also named trad_unix_bfd_copy_private_bfd_data.
4290 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4292 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4293 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4294 returns NULL, it is not an error. It's possible that some of
4295 these checks are not necessary (because the size can never be
4296 zero), but putting in the checks is the conservative thing to do
4297 in light of the fact that some of these malloc calls replaced
4298 unchecked alloca calls, in which a zero argument would work fine.
4300 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4302 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4303 duplicate definition.
4304 (osf_core_bfd_is_local_label): Define.
4306 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4307 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4308 failure indication, it merely means there are no relocs.
4310 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4311 after NAME, since SunOS /bin/cc can't handle it.

4315 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

4320 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4321 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4322 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4324 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4326 * som.c (som_prep_for_fixups): Detect section symbols based

4331 (som_slurp_symbol_table): Recognize both forms of section symbol
4332 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4333 section symbols to be the name of the section they represent.
4334 Debugging symbols begin with "L$0\001", not just "L$".

4389 * som.c (som_prep_for_fixups): A relocation involving the section
4390 symbol for the *ABS* section is really a relocation involving
4392 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4393 undefined symbols. Correctly distinguish between debugger symbols
4394 and section symbols.
4396 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4397 for spaces and subspaces.
4399 * som.c (som_bfd_count_ar_symbols): Fix typo.

4404 prepared to handle multiple sections with the same name.
4405 (setup_sections): Allocate space on the BFD's obstack to hold

4433 cruft (like the #pragma alloca for AIX).
4434 In addition to that problem, the C alloca calls xmalloc, which
4435 means checking for being out of memory can't work right. The
4436 following changes remove all uses of alloca from BFD.
4437 * hosts/solaris2.h: Remove alloca cruft.
4438 * som.c: Replace alloca with a fixed size auto array.

4480 include it in elf32-hppa.h.
4482 * som.c (log2): Return -1 on error rather than aborting.
4483 (setup_sections): Bubble up an error from log2.
4485 * Changes to make HP C compiler happy in both traditional
4487 * som.c (hppa_som_gen_reloc_type): Use correct enum type for

4773 * section.c (bfd_get_section_contents): Since this function reads
4774 unrelocated contents, the section's raw size is always the one to
4775 use for bounds checking.

4784 current offset in the section plus the number of bytes of padding
4785 that will actually be retained.
4786 (b_out_relax_section): If a section contains no relocations, don't
4787 bother processing them.
4788 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4792 that reloc->addend falls between the current source offset and the
4793 raw size of the input section.

5275 _bfd_generic_link_write_global_symbol): Don't require that all
5276 references to a common symbol be themselves common symbols.

5321 (only testing for m68k and vax at the moment); do verify that the
5322 preprocessor didn't trash the arch name inside the string version.

5353 bfd_som_set_subsection_attributes): Change parameters from char
5354 to int. Following a prototype with an old-style function definition

5461 use get_value to get the symbol value and check for undefined
5463 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5464 undefined, look it up in the linker hash table.
5466 * aoutx.h (translate_symbol_table): The string index 0 has a

5491 The sparc (and possibly other?) NLM format requires a different
5492 way to write exports, so add a write_export field to the backend
5493 data (and set it to NULL for everything but the sparc).
