4318 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4320 * som.h (som_copyable_section_data_struct): New structure
4321 containing all the private section information which needs
4322 to be copied from input section to output section during
4324 (som_section_data_struct): Remove several fields now in
4325 som_copyable_section_data_struct. Make the space and
4326 subspace dictionaries be pointers (to save space when
4327 only reading objects).
4329 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4330 some references changed. Allocate a copyable data stucture if
4331 none exists. Store info into the copyable data structure.
4332 (bfd_som_set_subsection_attributes): Likewise.
4333 (som_is_space, som_is_subspace, som_is_container): New functions.
4334 Use these instead of directly accessing private data.
4335 (som_prep_headers): Allocate space and subspace headers here.
4336 Fill in some fields in the space/subspace headers from the
4338 (som_bfd_copy_private_section_data): Only copy the stuff
4339 that we really need to make objcopy and strip work. Allocate
4340 the copy_data structure for the output bfd before copying.
4342 * som.h (struct som_exec_data): New structure to hold exec
4343 info that must be preserved when running objcopy/strip.
4344 (struct somdata): Add new "exec_data" field and accessor
4345 macro. Add some comments on how the various fields are used.
4346 (som_section_data_struct): Make is_space and is_subspace bitfields.
4347 Delete unused subspace_index. All references now use the
4348 target_index field within the section structure itself.
4350 * som.c (make_unique_section): Delete unused declaration.
4351 (som_bfd_copy_private_bfd_data): New function.
4352 (som_object_setup): Allocate space for and save exec information
4353 that needs to be copied during objcopy/strip.
4354 (som_mkobject): Do not allocate space for a file header here.
4355 It is not used when only reading SOM objects.
4356 (som_prep_headers): Allocate space for and attach a file header
4357 to the output bfd. For executables, use the saved system_id
4358 value rather than trying to guess the right value. Do not abort
4359 wwhen setting file_hdr->entry* for executables.
4360 (som_begin_writing): For executables, set the exec_entry and
4362 (som_copy_private_backend_section_data): Always return a value.
4364 * libhppa.h (PA_PAGESIZE): Define.
4366 * som.c (SOM_ALIGN): Define.
4367 (som_begin_writing): If writing an executable, initialize all
4368 fields in the exec header to zero. Update fields in the exec
4369 header as sizes of loadable subspaces are computed. Carefully
4370 preserve alignments when building executables. Actually write the
4371 exec after all the fields are filled in.
4373 * Better long-filename handling. Reads SOM ABI compliant extended
4374 names, but doesn't quite write compliant extended names yet.
4375 * som.c (som_slurp_extended_name_table): Delete function. The
4376 generic code will handle things correctly.
4377 (som_slurp_armap): Seek to the beginning of the next member.
4378 (normalize): New function.
4379 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4380 name table into account when computing the file offsets in the
4381 SOM dictionary. Make sure to align to an even boundary.
4382 (som_write_armap): Initialize the checksum to zero.
4383 (ar_maxchars): Fix. Opps.
4385 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4387 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4388 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4390 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4392 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4393 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4394 * bfd-in2.h: Regenerated.
4396 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4397 this was also named trad_unix_bfd_copy_private_bfd_data.
4399 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4401 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4402 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4403 returns NULL, it is not an error. It's possible that some of
4404 these checks are not necessary (because the size can never be
4405 zero), but putting in the checks is the conservative thing to do
4406 in light of the fact that some of these malloc calls replaced
4407 unchecked alloca calls, in which a zero argument would work fine.
4409 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4411 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4412 duplicate definition.
4413 (osf_core_bfd_is_local_label): Define.
4415 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4416 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4417 failure indication, it merely means there are no relocs.
4419 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4420 after NAME, since SunOS /bin/cc can't handle it.
4422 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4424 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4425 From sukes@glue.umd.edu (Tasuki Hirata).
4427 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4429 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4430 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4431 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4433 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4435 * som.c (som_prep_for_fixups): Detect section symbols based
4436 on either the lack of private data or the symbol flags. Do not
4437 munge section symbol names anymore -- they no longer confuse GDB.
4438 (som_begin_writing): Leave space for an exec header if writing
4440 (som_slurp_symbol_table): Recognize both forms of section symbol
4441 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4442 section symbols to be the name of the section they represent.
4443 Debugging symbols begin with "L$0\001", not just "L$".
4445 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4447 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4449 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4450 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4451 and bfd_is_local_label.
4453 * targets.c: Add new entries to the bfd_target structure.
4455 * bfd.c (bfd_copy_private_bfd_data): New definition.
4457 * section.c (bfd_copy_private_section_data): New definition.
4459 * syms.c (bfd_is_local_label): New definition.
4461 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4463 * libbfd.c (bfd_generic_is_local_label): New function.
4465 * *-core.c: Provide default definitions for new functions in
4466 the target vector which all point to bfd_false.
4468 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4469 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4470 Default new vectors for copying private backend data to bfd_true.
4471 Default new vector for determining if a symbol is a local label
4472 to bfd_generic_is_local_label.
4474 * som.c (som_bfd_copy_private_section_data): New function.
4475 (som_bfd_is_local_label): New function.
4476 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4478 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4480 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4482 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4484 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4487 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4488 Indent some of them to GNU standards.
4490 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4491 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4492 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4493 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4494 Update copyright years.
4496 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4498 * som.c (som_prep_for_fixups): A relocation involving the section
4499 symbol for the *ABS* section is really a relocation involving
4501 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4502 undefined symbols. Correctly distinguish between debugger symbols
4503 and section symbols.
4505 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4506 for spaces and subspaces.
4508 * som.c (som_bfd_count_ar_symbols): Fix typo.
4510 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4511 HAS_RELOC based on the object's magic number.
4512 (make_unique_section): Delete function. BFD and its users are
4513 prepared to handle multiple sections with the same name.
4514 (setup_sections): Allocate space on the BFD's obstack to hold
4515 section names. Use bfd_make_setion_anyway rather than the
4516 obsolete make_unique_section.
4517 (som_prep_headers): Choose the correct SOM magic number based
4519 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4521 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4523 * elf32-ppc.c: Renamed from elf32-powerpc.c.

4533 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4534 is always located at the start of the data section to allow
4535 recovery of the dynamic info from a stripped executable.

4539 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4541 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4542 cruft (like the #pragma alloca for AIX).
4543 In addition to that problem, the C alloca calls xmalloc, which
4544 means checking for being out of memory can't work right. The
4545 following changes remove all uses of alloca from BFD.
4546 * hosts/solaris2.h: Remove alloca cruft.
4547 * som.c: Replace alloca with a fixed size auto array.
4548 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4549 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4550 sunos.c: Replace alloca with malloc and appropriate error checking and
4552 * linker.c: Replace alloca with obstack_alloc.
4553 * libbfd.h: Rebuilt.
4555 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4557 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4560 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4562 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4563 Elf*_Off typedefs by their expansion, the typedefs have been
4564 removed from include/elf/internal.h.
4565 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4566 SHT_PROGBITS section.
4568 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4570 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

4576 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4577 return from bfd_seek indicates an error.
4578 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4579 TRAD_CORE_STACK_OFFSET.
4580 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4581 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4583 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4585 * som.[ch]: Do not include libhppa.h in som.c, instead include
4588 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4589 include it in elf32-hppa.h.
4591 * som.c (log2): Return -1 on error rather than aborting.
4592 (setup_sections): Bubble up an error from log2.
4594 * Changes to make HP C compiler happy in both traditional
4596 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4598 (bfd_som_set_section_attributes): Use unsigned int rather than
4599 unsigned char to avoid GNU-C extensions.
4600 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4601 or failure rather than aborting on failure.
4603 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4605 (bfd_som_attach_aux_hdr): Add prototype.
4606 (hppa_som-gen_reloc_type): Likewise.
4608 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4609 (hppa_look_for_stubs_in_section): Do not return false on failure
4610 until rest of code is ready to handle it. Abort for now.

4635 action in case where caller specified no argument relocation.
4636 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4637 right in the original relocation and the stub's relocation.

4640 unused symbols argument.
4642 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

4644 Set reloc->sym_ptr_ptr appropriately.
4645 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4646 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4647 argument. Use the output symbols when canonicalizing the relocs,
4648 creating them if necessary.
4650 * linker.c (_bfd_generic_link_output_symbols): Do not
4651 rebuild/clobber the output symbols if they already exist.
4653 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4655 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

4657 * bfd-in2.h: Rebuilt.
4659 * srec.c (hex_value): Always set to a size of 256 bytes.
4660 (srec_init): Cosmetic changes.
4662 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

4665 PARAMize and staticize rest of functions. Delete unused
4666 functions. Delete unused/unnecessary arguments to some functions.
4667 Group static vars together. Abort for bad errors until we have
4668 error code propogation working. Work on spacing and indention.
4669 Add FIXMEs for unresolved problems. Use enums rather than
4670 #defines for lots of things. Merge two functions which build
4671 linker stubs into a single function (so they can easily share a
4672 ton of common code).
4674 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4676 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4677 avoid depending upon right shifts of signed numbers, and to
4678 correct handling of src_mask with lower bits zero.
4680 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.

4708 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
4709 (elf_hppa_tc_make_sections): Likewise.
4710 (elf_hppa_final_processing): Add extern decl.
4712 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
4713 comments. PARAMize some static functions. Delete unused functions.
4714 Delete unused/unnecessary arguments to many functions. Group
4715 static vars together. Collapse common case statements together
4716 in many places. Use default case when possible instead of listing
4717 each case separately. Abort for bad errors until we get error
4718 code propogation working. Work on spacing and indention problems.
4719 Add FIXMEs for some unresolved problems. Delete hopelessly broken
4720 COMPLEX relocation support (it's never used anyway).
4721 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
4722 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
4723 (elf_hppa_tc_make_sections): Likewise.

4736 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
4738 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

4764 * elfcode.h (alloca): Delete declaration.
4766 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
4767 number rather than HP9000S800_ID. Note som.c is careful
4768 to make sure CPU_PA_RISC1_0 is always defined.
4770 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
4772 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply
4773 flags to explicit compile actions.

5573 undefined, look it up in the linker hash table.
5575 * aoutx.h (translate_symbol_table): The string index 0 has a

5600 The sparc (and possibly other?) NLM format requires a different
5601 way to write exports, so add a write_export field to the backend
5602 data (and set it to NULL for everything but the sparc).
