4295 Fill in some fields in the space/subspace headers from the
4297 (som_bfd_copy_private_section_data): Only copy the stuff
4298 that we really need to make objcopy and strip work. Allocate

4317 value rather than trying to guess the right value. Do not abort
4318 wwhen setting file_hdr->entry* for executables.
4319 (som_begin_writing): For executables, set the exec_entry and
4321 (som_copy_private_backend_section_data): Always return a value.
4323 * libhppa.h (PA_PAGESIZE): Define.
4325 * som.c (SOM_ALIGN): Define.
4326 (som_begin_writing): If writing an executable, initialize all
4327 fields in the exec header to zero. Update fields in the exec
4328 header as sizes of loadable subspaces are computed. Carefully
4329 preserve alignments when building executables. Actually write the
4330 exec after all the fields are filled in.
4332 * Better long-filename handling. Reads SOM ABI compliant extended
4333 names, but doesn't quite write compliant extended names yet.
4334 * som.c (som_slurp_extended_name_table): Delete function. The
4335 generic code will handle things correctly.
4336 (som_slurp_armap): Seek to the beginning of the next member.
4337 (normalize): New function.
4338 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4339 name table into account when computing the file offsets in the
4340 SOM dictionary. Make sure to align to an even boundary.
4341 (som_write_armap): Initialize the checksum to zero.
4342 (ar_maxchars): Fix. Opps.
4344 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4346 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4347 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4349 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4351 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4352 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4353 * bfd-in2.h: Regenerated.
4355 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4356 this was also named trad_unix_bfd_copy_private_bfd_data.
4358 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4360 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4361 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4362 returns NULL, it is not an error. It's possible that some of
4363 these checks are not necessary (because the size can never be
4364 zero), but putting in the checks is the conservative thing to do
4365 in light of the fact that some of these malloc calls replaced
4366 unchecked alloca calls, in which a zero argument would work fine.
4368 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4370 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4371 duplicate definition.
4372 (osf_core_bfd_is_local_label): Define.
4374 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4375 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4376 failure indication, it merely means there are no relocs.
4378 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4379 after NAME, since SunOS /bin/cc can't handle it.
4381 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4383 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4384 From sukes@glue.umd.edu (Tasuki Hirata).
4386 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4388 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4389 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4390 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4392 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4394 * som.c (som_prep_for_fixups): Detect section symbols based
4395 on either the lack of private data or the symbol flags. Do not
4396 munge section symbol names anymore -- they no longer confuse GDB.
4397 (som_begin_writing): Leave space for an exec header if writing
4399 (som_slurp_symbol_table): Recognize both forms of section symbol
4400 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4401 section symbols to be the name of the section they represent.
4402 Debugging symbols begin with "L$0\001", not just "L$".
4404 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4406 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4408 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4409 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4410 and bfd_is_local_label.
4412 * targets.c: Add new entries to the bfd_target structure.
4414 * bfd.c (bfd_copy_private_bfd_data): New definition.

4425 the target vector which all point to bfd_false.
4427 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4428 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4429 Default new vectors for copying private backend data to bfd_true.
4430 Default new vector for determining if a symbol is a local label
4431 to bfd_generic_is_local_label.
4433 * som.c (som_bfd_copy_private_section_data): New function.
4434 (som_bfd_is_local_label): New function.
4435 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4437 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4439 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4441 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4443 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4446 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4447 Indent some of them to GNU standards.
4449 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4450 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4451 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4452 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4453 Update copyright years.
4455 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4457 * som.c (som_prep_for_fixups): A relocation involving the section
4458 symbol for the *ABS* section is really a relocation involving
4460 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4461 undefined symbols. Correctly distinguish between debugger symbols
4462 and section symbols.
4464 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4465 for spaces and subspaces.
4467 * som.c (som_bfd_count_ar_symbols): Fix typo.
4469 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4470 HAS_RELOC based on the object's magic number.
4471 (make_unique_section): Delete function. BFD and its users are
4472 prepared to handle multiple sections with the same name.
4473 (setup_sections): Allocate space on the BFD's obstack to hold
4474 section names. Use bfd_make_setion_anyway rather than the
4475 obsolete make_unique_section.
4476 (som_prep_headers): Choose the correct SOM magic number based
4478 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4498 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4500 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4501 cruft (like the #pragma alloca for AIX).
4502 In addition to that problem, the C alloca calls xmalloc, which
4503 means checking for being out of memory can't work right. The
4504 following changes remove all uses of alloca from BFD.
4505 * hosts/solaris2.h: Remove alloca cruft.
4506 * som.c: Replace alloca with a fixed size auto array.

4511 * linker.c: Replace alloca with obstack_alloc.
4512 * libbfd.h: Rebuilt.
4514 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)

4519 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4521 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4522 Elf*_Off typedefs by their expansion, the typedefs have been
4523 removed from include/elf/internal.h.
4524 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4525 SHT_PROGBITS section.
4527 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4529 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4535 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4536 return from bfd_seek indicates an error.
4537 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4538 TRAD_CORE_STACK_OFFSET.
4539 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4540 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4542 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4544 * som.[ch]: Do not include libhppa.h in som.c, instead include
4547 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4548 include it in elf32-hppa.h.
4550 * som.c (log2): Return -1 on error rather than aborting.
4551 (setup_sections): Bubble up an error from log2.
4553 * Changes to make HP C compiler happy in both traditional
4555 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4557 (bfd_som_set_section_attributes): Use unsigned int rather than
4558 unsigned char to avoid GNU-C extensions.
4559 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4560 or failure rather than aborting on failure.
4562 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4564 (bfd_som_attach_aux_hdr): Add prototype.
4565 (hppa_som-gen_reloc_type): Likewise.

4603 Set reloc->sym_ptr_ptr appropriately.
4604 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4605 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4606 argument. Use the output symbols when canonicalizing the relocs,
4607 creating them if necessary.
4609 * linker.c (_bfd_generic_link_output_symbols): Do not
4610 rebuild/clobber the output symbols if they already exist.

4624 PARAMize and staticize rest of functions. Delete unused
4625 functions. Delete unused/unnecessary arguments to some functions.

4627 error code propogation working. Work on spacing and indention.
4628 Add FIXMEs for unresolved problems. Use enums rather than
4629 #defines for lots of things. Merge two functions which build
4630 linker stubs into a single function (so they can easily share a
4631 ton of common code).
4633 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4635 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4636 avoid depending upon right shifts of signed numbers, and to
4637 correct handling of src_mask with lower bits zero.

4669 (elf_hppa_final_processing): Add extern decl.
4671 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4672 comments. PARAMize some static functions. Delete unused functions.

4674 static vars together. Collapse common case statements together
4675 in many places. Use default case when possible instead of listing
4676 each case separately. Abort for bad errors until we get error
4677 code propogation working. Work on spacing and indention problems.
4678 Add FIXMEs for some unresolved problems. Delete hopelessly broken
4679 COMPLEX relocation support (it's never used anyway).
4680 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4681 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4682 (elf_hppa_tc_make_sections): Likewise.

4725 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
4726 number rather than HP9000S800_ID. Note som.c is careful
4727 to make sure CPU_PA_RISC1_0 is always defined.
4729 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
4731 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

4748 * coff-alpha.c (alpha_relocate_section): Rewrite mask and shift
4749 operation to avoid OSF 1.3 cc bug.
4750 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
4751 and bss_size bfd_size_type instead of unsigned long. Make
4752 text_start and data_start bfd_vma instead of unsigned long.

5269 * srec.c (srec_write_record): Put CONST keyword for "src" before
5270 "unsigned", some compilers don't like it after "unsigned".
5271 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

5343 _bfd_generic_link_write_global_symbol): Don't require that all

5421 bfd_som_set_subsection_attributes): Change parameters from char
5422 to int. Following a prototype with an old-style function definition

5529 use get_value to get the symbol value and check for undefined
5531 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5532 undefined, look it up in the linker hash table.
5534 * aoutx.h (translate_symbol_table): The string index 0 has a

5559 The sparc (and possibly other?) NLM format requires a different
5560 way to write exports, so add a write_export field to the backend
5561 data (and set it to NULL for everything but the sparc).
