1559 an empty .plt section.
1560 (elf32_sparc_relocate_section): For a GOT reloc against a global
1561 symbol when no dynamic object was seen, initialize the contents of

5229 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5231 * som.h (som_copyable_section_data_struct): New structure
5232 containing all the private section information which needs
5233 to be copied from input section to output section during
5235 (som_section_data_struct): Remove several fields now in
5236 som_copyable_section_data_struct. Make the space and
5237 subspace dictionaries be pointers (to save space when
5238 only reading objects).
5240 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
5241 some references changed. Allocate a copyable data stucture if
5242 none exists. Store info into the copyable data structure.
5243 (bfd_som_set_subsection_attributes): Likewise.
5244 (som_is_space, som_is_subspace, som_is_container): New functions.
5245 Use these instead of directly accessing private data.
5246 (som_prep_headers): Allocate space and subspace headers here.
5247 Fill in some fields in the space/subspace headers from the
5249 (som_bfd_copy_private_section_data): Only copy the stuff
5250 that we really need to make objcopy and strip work. Allocate
5251 the copy_data structure for the output bfd before copying.
5253 * som.h (struct som_exec_data): New structure to hold exec
5254 info that must be preserved when running objcopy/strip.
5255 (struct somdata): Add new "exec_data" field and accessor
5256 macro. Add some comments on how the various fields are used.
5257 (som_section_data_struct): Make is_space and is_subspace bitfields.
5258 Delete unused subspace_index. All references now use the
5259 target_index field within the section structure itself.
5261 * som.c (make_unique_section): Delete unused declaration.
5262 (som_bfd_copy_private_bfd_data): New function.
5263 (som_object_setup): Allocate space for and save exec information
5264 that needs to be copied during objcopy/strip.
5265 (som_mkobject): Do not allocate space for a file header here.
5266 It is not used when only reading SOM objects.
5267 (som_prep_headers): Allocate space for and attach a file header
5268 to the output bfd. For executables, use the saved system_id
5269 value rather than trying to guess the right value. Do not abort
5270 wwhen setting file_hdr->entry* for executables.
5271 (som_begin_writing): For executables, set the exec_entry and
5273 (som_copy_private_backend_section_data): Always return a value.
5275 * libhppa.h (PA_PAGESIZE): Define.
5277 * som.c (SOM_ALIGN): Define.
5278 (som_begin_writing): If writing an executable, initialize all
5279 fields in the exec header to zero. Update fields in the exec
5280 header as sizes of loadable subspaces are computed. Carefully
5281 preserve alignments when building executables. Actually write the
5282 exec after all the fields are filled in.
5284 * Better long-filename handling. Reads SOM ABI compliant extended
5285 names, but doesn't quite write compliant extended names yet.
5286 * som.c (som_slurp_extended_name_table): Delete function. The
5287 generic code will handle things correctly.
5288 (som_slurp_armap): Seek to the beginning of the next member.
5289 (normalize): New function.
5290 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
5291 name table into account when computing the file offsets in the
5292 SOM dictionary. Make sure to align to an even boundary.
5293 (som_write_armap): Initialize the checksum to zero.
5294 (ar_maxchars): Fix. Opps.
5296 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5298 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
5299 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
5301 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5303 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5304 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5305 * bfd-in2.h: Regenerated.
5307 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5308 this was also named trad_unix_bfd_copy_private_bfd_data.
5310 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5312 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5313 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5314 returns NULL, it is not an error. It's possible that some of
5315 these checks are not necessary (because the size can never be
5316 zero), but putting in the checks is the conservative thing to do
5317 in light of the fact that some of these malloc calls replaced
5318 unchecked alloca calls, in which a zero argument would work fine.
5320 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5322 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5323 duplicate definition.
5324 (osf_core_bfd_is_local_label): Define.
5326 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5327 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5328 failure indication, it merely means there are no relocs.
5330 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5331 after NAME, since SunOS /bin/cc can't handle it.
5333 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5335 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5336 From sukes@glue.umd.edu (Tasuki Hirata).
5338 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5340 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5341 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5342 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5344 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5346 * som.c (som_prep_for_fixups): Detect section symbols based
5347 on either the lack of private data or the symbol flags. Do not
5348 munge section symbol names anymore -- they no longer confuse GDB.
5349 (som_begin_writing): Leave space for an exec header if writing
5351 (som_slurp_symbol_table): Recognize both forms of section symbol
5352 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5353 section symbols to be the name of the section they represent.
5354 Debugging symbols begin with "L$0\001", not just "L$".
5356 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5358 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5360 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5361 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5362 and bfd_is_local_label.
5364 * targets.c: Add new entries to the bfd_target structure.
5366 * bfd.c (bfd_copy_private_bfd_data): New definition.
5368 * section.c (bfd_copy_private_section_data): New definition.
5370 * syms.c (bfd_is_local_label): New definition.
5372 * libbfd-in.h (bfd_generic_is_local_label): Declare.
5374 * libbfd.c (bfd_generic_is_local_label): New function.
5376 * *-core.c: Provide default definitions for new functions in
5377 the target vector which all point to bfd_false.
5379 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5380 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5381 Default new vectors for copying private backend data to bfd_true.
5382 Default new vector for determining if a symbol is a local label
5383 to bfd_generic_is_local_label.
5385 * som.c (som_bfd_copy_private_section_data): New function.
5386 (som_bfd_is_local_label): New function.
5387 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5389 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5391 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5393 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5395 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5398 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5399 Indent some of them to GNU standards.
5401 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5402 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5403 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5404 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5405 Update copyright years.
5407 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5409 * som.c (som_prep_for_fixups): A relocation involving the section
5410 symbol for the *ABS* section is really a relocation involving
5412 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5413 undefined symbols. Correctly distinguish between debugger symbols
5414 and section symbols.
5416 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5417 for spaces and subspaces.
5419 * som.c (som_bfd_count_ar_symbols): Fix typo.
5421 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5422 HAS_RELOC based on the object's magic number.
5423 (make_unique_section): Delete function. BFD and its users are
5424 prepared to handle multiple sections with the same name.
5425 (setup_sections): Allocate space on the BFD's obstack to hold
5426 section names. Use bfd_make_setion_anyway rather than the
5427 obsolete make_unique_section.
5428 (som_prep_headers): Choose the correct SOM magic number based
5430 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5432 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5434 * elf32-ppc.c: Renamed from elf32-powerpc.c.

5444 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5445 is always located at the start of the data section to allow
5446 recovery of the dynamic info from a stripped executable.

5450 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5452 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5453 cruft (like the #pragma alloca for AIX).
5454 In addition to that problem, the C alloca calls xmalloc, which
5455 means checking for being out of memory can't work right. The
5456 following changes remove all uses of alloca from BFD.
5457 * hosts/solaris2.h: Remove alloca cruft.
5458 * som.c: Replace alloca with a fixed size auto array.
5459 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

5461 sunos.c: Replace alloca with malloc and appropriate error checking and
5463 * linker.c: Replace alloca with obstack_alloc.
5464 * libbfd.h: Rebuilt.
5466 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5468 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5471 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5473 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5474 Elf*_Off typedefs by their expansion, the typedefs have been
5475 removed from include/elf/internal.h.
5476 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5477 SHT_PROGBITS section.
5479 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5481 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5487 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5488 return from bfd_seek indicates an error.
5489 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5490 TRAD_CORE_STACK_OFFSET.
5491 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5492 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5494 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5496 * som.[ch]: Do not include libhppa.h in som.c, instead include
5499 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5500 include it in elf32-hppa.h.
5502 * som.c (log2): Return -1 on error rather than aborting.
5503 (setup_sections): Bubble up an error from log2.
5505 * Changes to make HP C compiler happy in both traditional
5507 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5509 (bfd_som_set_section_attributes): Use unsigned int rather than
5510 unsigned char to avoid GNU-C extensions.
5511 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5512 or failure rather than aborting on failure.
5514 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5516 (bfd_som_attach_aux_hdr): Add prototype.
5517 (hppa_som-gen_reloc_type): Likewise.
5519 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5520 (hppa_look_for_stubs_in_section): Do not return false on failure
5521 until rest of code is ready to handle it. Abort for now.

5546 action in case where caller specified no argument relocation.
5547 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
5548 right in the original relocation and the stub's relocation.

5551 unused symbols argument.
5553 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

5555 Set reloc->sym_ptr_ptr appropriately.
5556 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
5557 (hppa_elf_look_for_stubs_in_section): No longer need symbols
5558 argument. Use the output symbols when canonicalizing the relocs,
5559 creating them if necessary.
5561 * linker.c (_bfd_generic_link_output_symbols): Do not
5562 rebuild/clobber the output symbols if they already exist.
5564 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
5566 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

5568 * bfd-in2.h: Rebuilt.
5570 * srec.c (hex_value): Always set to a size of 256 bytes.
5571 (srec_init): Cosmetic changes.
5573 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

5576 PARAMize and staticize rest of functions. Delete unused
5577 functions. Delete unused/unnecessary arguments to some functions.
5578 Group static vars together. Abort for bad errors until we have
5579 error code propogation working. Work on spacing and indention.
5580 Add FIXMEs for unresolved problems. Use enums rather than
5581 #defines for lots of things. Merge two functions which build
5582 linker stubs into a single function (so they can easily share a
5583 ton of common code).
5585 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
5587 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
5588 avoid depending upon right shifts of signed numbers, and to
5589 correct handling of src_mask with lower bits zero.
5591 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.

5619 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
5620 (elf_hppa_tc_make_sections): Likewise.
5621 (elf_hppa_final_processing): Add extern decl.
5623 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
5624 comments. PARAMize some static functions. Delete unused functions.
5625 Delete unused/unnecessary arguments to many functions. Group
5626 static vars together. Collapse common case statements together
5627 in many places. Use default case when possible instead of listing
5628 each case separately. Abort for bad errors until we get error
5629 code propogation working. Work on spacing and indention problems.
5630 Add FIXMEs for some unresolved problems. Delete hopelessly broken
5631 COMPLEX relocation support (it's never used anyway).
5632 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
5633 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
5634 (elf_hppa_tc_make_sections): Likewise.

5647 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
5649 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

5675 * elfcode.h (alloca): Delete declaration.
5677 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
5678 number rather than HP9000S800_ID. Note som.c is careful
5679 to make sure CPU_PA_RISC1_0 is always defined.
5681 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
5683 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply
5684 flags to explicit compile actions.

6481 use get_value to get the symbol value and check for undefined
6483 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
6484 undefined, look it up in the linker hash table.
6486 * aoutx.h (translate_symbol_table): The string index 0 has a

6511 The sparc (and possibly other?) NLM format requires a different
6512 way to write exports, so add a write_export field to the backend
6513 data (and set it to NULL for everything but the sparc).
