4300 Fill in some fields in the space/subspace headers from the
4302 (som_bfd_copy_private_section_data): Only copy the stuff
4303 that we really need to make objcopy and strip work. Allocate
4304 the copy_data structure for the output bfd before copying.

4307 info that must be preserved when running objcopy/strip.

4309 macro. Add some comments on how the various fields are used.
4310 (som_section_data_struct): Make is_space and is_subspace bitfields.

4319 It is not used when only reading SOM objects.
4320 (som_prep_headers): Allocate space for and attach a file header
4321 to the output bfd. For executables, use the saved system_id
4322 value rather than trying to guess the right value. Do not abort
4323 wwhen setting file_hdr->entry* for executables.
4324 (som_begin_writing): For executables, set the exec_entry and
4326 (som_copy_private_backend_section_data): Always return a value.
4328 * libhppa.h (PA_PAGESIZE): Define.
4330 * som.c (SOM_ALIGN): Define.
4331 (som_begin_writing): If writing an executable, initialize all
4332 fields in the exec header to zero. Update fields in the exec
4333 header as sizes of loadable subspaces are computed. Carefully
4334 preserve alignments when building executables. Actually write the
4335 exec after all the fields are filled in.
4337 * Better long-filename handling. Reads SOM ABI compliant extended
4338 names, but doesn't quite write compliant extended names yet.
4339 * som.c (som_slurp_extended_name_table): Delete function. The
4340 generic code will handle things correctly.
4341 (som_slurp_armap): Seek to the beginning of the next member.
4342 (normalize): New function.
4343 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4344 name table into account when computing the file offsets in the
4345 SOM dictionary. Make sure to align to an even boundary.
4346 (som_write_armap): Initialize the checksum to zero.
4347 (ar_maxchars): Fix. Opps.
4349 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4351 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4352 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4354 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4356 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4357 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4358 * bfd-in2.h: Regenerated.
4360 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4361 this was also named trad_unix_bfd_copy_private_bfd_data.
4363 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4365 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4366 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4367 returns NULL, it is not an error. It's possible that some of
4368 these checks are not necessary (because the size can never be
4369 zero), but putting in the checks is the conservative thing to do
4370 in light of the fact that some of these malloc calls replaced
4371 unchecked alloca calls, in which a zero argument would work fine.
4373 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4375 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4376 duplicate definition.
4377 (osf_core_bfd_is_local_label): Define.
4379 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4380 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4381 failure indication, it merely means there are no relocs.
4383 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4384 after NAME, since SunOS /bin/cc can't handle it.
4386 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4388 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4389 From sukes@glue.umd.edu (Tasuki Hirata).
4391 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4393 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4394 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4395 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4397 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4399 * som.c (som_prep_for_fixups): Detect section symbols based
4400 on either the lack of private data or the symbol flags. Do not
4401 munge section symbol names anymore -- they no longer confuse GDB.
4402 (som_begin_writing): Leave space for an exec header if writing
4404 (som_slurp_symbol_table): Recognize both forms of section symbol
4405 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4406 section symbols to be the name of the section they represent.
4407 Debugging symbols begin with "L$0\001", not just "L$".
4409 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4411 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4413 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4414 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4415 and bfd_is_local_label.
4417 * targets.c: Add new entries to the bfd_target structure.
4419 * bfd.c (bfd_copy_private_bfd_data): New definition.

4427 * libbfd.c (bfd_generic_is_local_label): New function.
4429 * *-core.c: Provide default definitions for new functions in
4430 the target vector which all point to bfd_false.
4432 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4433 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4434 Default new vectors for copying private backend data to bfd_true.
4435 Default new vector for determining if a symbol is a local label
4436 to bfd_generic_is_local_label.
4438 * som.c (som_bfd_copy_private_section_data): New function.
4439 (som_bfd_is_local_label): New function.
4440 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4442 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4444 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4446 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4448 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4451 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4452 Indent some of them to GNU standards.
4454 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4455 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4456 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4457 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4458 Update copyright years.
4460 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4462 * som.c (som_prep_for_fixups): A relocation involving the section
4463 symbol for the *ABS* section is really a relocation involving
4465 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4466 undefined symbols. Correctly distinguish between debugger symbols
4467 and section symbols.
4469 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4470 for spaces and subspaces.
4472 * som.c (som_bfd_count_ar_symbols): Fix typo.
4474 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4475 HAS_RELOC based on the object's magic number.
4476 (make_unique_section): Delete function. BFD and its users are
4477 prepared to handle multiple sections with the same name.
4478 (setup_sections): Allocate space on the BFD's obstack to hold
4479 section names. Use bfd_make_setion_anyway rather than the
4480 obsolete make_unique_section.
4481 (som_prep_headers): Choose the correct SOM magic number based
4483 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4485 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4487 * elf32-ppc.c: Renamed from elf32-powerpc.c.

4497 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4498 is always located at the start of the data section to allow
4499 recovery of the dynamic info from a stripped executable.

4503 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4505 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4506 cruft (like the #pragma alloca for AIX).
4507 In addition to that problem, the C alloca calls xmalloc, which
4508 means checking for being out of memory can't work right. The
4509 following changes remove all uses of alloca from BFD.
4510 * hosts/solaris2.h: Remove alloca cruft.
4511 * som.c: Replace alloca with a fixed size auto array.

4514 sunos.c: Replace alloca with malloc and appropriate error checking and
4516 * linker.c: Replace alloca with obstack_alloc.
4517 * libbfd.h: Rebuilt.
4519 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4521 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4524 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4526 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4527 Elf*_Off typedefs by their expansion, the typedefs have been
4528 removed from include/elf/internal.h.
4529 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4530 SHT_PROGBITS section.
4532 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4534 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4540 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4541 return from bfd_seek indicates an error.
4542 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4543 TRAD_CORE_STACK_OFFSET.
4544 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4545 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4547 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4549 * som.[ch]: Do not include libhppa.h in som.c, instead include
4552 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4553 include it in elf32-hppa.h.
4555 * som.c (log2): Return -1 on error rather than aborting.
4556 (setup_sections): Bubble up an error from log2.
4558 * Changes to make HP C compiler happy in both traditional
4560 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4562 (bfd_som_set_section_attributes): Use unsigned int rather than
4563 unsigned char to avoid GNU-C extensions.
4564 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4565 or failure rather than aborting on failure.
4567 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4569 (bfd_som_attach_aux_hdr): Add prototype.
4570 (hppa_som-gen_reloc_type): Likewise.

4604 unused symbols argument.
4606 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

4608 Set reloc->sym_ptr_ptr appropriately.
4609 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4610 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4611 argument. Use the output symbols when canonicalizing the relocs,
4612 creating them if necessary.
4614 * linker.c (_bfd_generic_link_output_symbols): Do not
4615 rebuild/clobber the output symbols if they already exist.
4617 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4619 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

4629 PARAMize and staticize rest of functions. Delete unused
4630 functions. Delete unused/unnecessary arguments to some functions.

4632 error code propogation working. Work on spacing and indention.
4633 Add FIXMEs for unresolved problems. Use enums rather than
4634 #defines for lots of things. Merge two functions which build
4635 linker stubs into a single function (so they can easily share a
4636 ton of common code).
4638 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4640 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4641 avoid depending upon right shifts of signed numbers, and to
4642 correct handling of src_mask with lower bits zero.

4674 (elf_hppa_final_processing): Add extern decl.
4676 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4677 comments. PARAMize some static functions. Delete unused functions.

4679 static vars together. Collapse common case statements together
4680 in many places. Use default case when possible instead of listing
4681 each case separately. Abort for bad errors until we get error
4682 code propogation working. Work on spacing and indention problems.
4683 Add FIXMEs for some unresolved problems. Delete hopelessly broken
4684 COMPLEX relocation support (it's never used anyway).
4685 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4686 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4687 (elf_hppa_tc_make_sections): Likewise.

4728 * elfcode.h (alloca): Delete declaration.
4730 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
4731 number rather than HP9000S800_ID. Note som.c is careful
4732 to make sure CPU_PA_RISC1_0 is always defined.
4734 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
4736 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

4753 * coff-alpha.c (alpha_relocate_section): Rewrite mask and shift
4754 operation to avoid OSF 1.3 cc bug.
4755 * ecoff.c (ecoff_write_object_contents): Make text_size, data_size
4756 and bss_size bfd_size_type instead of unsigned long. Make
4757 text_start and data_start bfd_vma instead of unsigned long.
4758 * ecofflink.c (ecoff_add_string): Remove incorrect cast of return
4761 Sun Feb 20 16:06:54 1994 Ian Lance Taylor (ian@lisa.cygnus.com)

5274 * srec.c (srec_write_record): Put CONST keyword for "src" before
5275 "unsigned", some compilers don't like it after "unsigned".
5276 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to

5426 bfd_som_set_subsection_attributes): Change parameters from char
5427 to int. Following a prototype with an old-style function definition

5534 use get_value to get the symbol value and check for undefined
5536 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
5537 undefined, look it up in the linker hash table.
5539 * aoutx.h (translate_symbol_table): The string index 0 has a

5564 The sparc (and possibly other?) NLM format requires a different
5565 way to write exports, so add a write_export field to the backend
5566 data (and set it to NULL for everything but the sparc).

5616 read_dynamic_relocs fields.
5617 * aout-target.h (MY(backend_data)): Initialize
