4329 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4331 Support for link_order types which generate relocs in order to
4332 support -Ur in the linker.
4333 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4334 from call to _bfd_generic_link_add_one_symbol.
4335 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4336 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4337 instead of bitsize to add_to_set call back.
4338 (_bfd_generic_final_link): Account for link_order relocs when
4339 allocating space for relocations. Handle them in link_order loop.
4340 (_bfd_generic_reloc_link_order): New function.
4341 (_bfd_default_link_order): If a reloc_link_order is seen here,
4343 (_bfd_count_link_order_relocs): New function.
4344 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
4345 argument from declaration.
4346 (_bfd_generic_reloc_link_order): Declare.
4347 (_bfd_count_link_order_relocs): Declare.
4348 * libbfd.h: Rebuilt.
4349 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
4350 call to _bfd_generic_link_add_one_symbol.
4351 (NAME(aout,final_link)): Account for link_order relocs when
4352 allocating space for relocations. Handle them after handling all
4354 (aout_link_reloc_link_order): New function.
4355 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
4356 call to _bfd_generic_link_add_one_symbol.
4357 (ecoff_bfd_final_link): Account for link_order relocs when
4358 allocating space for relocations. Handle them in link_order loop.
4359 (ecoff_link_write_external): Set the storage class of a defined
4360 linker created symbol based on the section it is in. Correct
4361 bfd_link_hash_weak case to use .sc rather than .st.
4362 (ecoff_reloc_link_order): New function.
4363 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4365 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
4367 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
4370 * cisco-core.c (cisco_core_file_p): Only pass one argument to
4371 bfd_zmalloc. Free a pointer, not a union.
4372 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
4374 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4376 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4378 * som.c (bfd_section_from_som_symbol): Only to do the value
4379 comparison for function symbols within executables.
4381 * som.c (bfd_section_from_som_symbol): Renamed from
4382 som_section_from_subspace_index. Pass in a native SOM symbol.
4383 For executables, iterate through the sections to find out
4384 which contains the symbol's address rather than using the
4385 symbol_info field. (symbol_info has a different meaning for
4386 dynamicly linked executables.)
4388 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4391 * som.c (som_begin_writing): Fix braino (one call to align
4392 space/subspace data was done unconditionally rather than
4393 just for executables.)
4395 * som.c (som_begin_writing): Align text in all executables to
4396 make HPUX kernel happy. Fixes strip/objcopy for shared
4399 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4401 * som.c (som_begin_writing): Account for alignment needs of
4402 subspaces too when writing executables. Never request a negative
4403 bss size. Fixes some problems with demand paged executables,
4404 still having problems with pure executables and shared executables.
4406 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4408 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4409 bfd_zalloc for rawptr, because later on we may call free, not
4412 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4413 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4414 * cisco-core.c: New file.
4415 * Makefile.in: Change accordingly.
4416 * configure.in: Recognize cisco_core_vec.
4417 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4418 * targets.c: Add cisco_core_vec.
4419 * bfd-in2.h: Rebuilt.
4421 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4423 * som.h (som_copyable_section_data_struct): New structure
4424 containing all the private section information which needs
4425 to be copied from input section to output section during
4427 (som_section_data_struct): Remove several fields now in
4428 som_copyable_section_data_struct. Make the space and
4429 subspace dictionaries be pointers (to save space when
4430 only reading objects).
4432 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4433 some references changed. Allocate a copyable data stucture if
4434 none exists. Store info into the copyable data structure.
4435 (bfd_som_set_subsection_attributes): Likewise.
4436 (som_is_space, som_is_subspace, som_is_container): New functions.
4437 Use these instead of directly accessing private data.
4438 (som_prep_headers): Allocate space and subspace headers here.
4439 Fill in some fields in the space/subspace headers from the
4441 (som_bfd_copy_private_section_data): Only copy the stuff
4442 that we really need to make objcopy and strip work. Allocate
4443 the copy_data structure for the output bfd before copying.
4445 * som.h (struct som_exec_data): New structure to hold exec
4446 info that must be preserved when running objcopy/strip.
4447 (struct somdata): Add new "exec_data" field and accessor
4448 macro. Add some comments on how the various fields are used.
4449 (som_section_data_struct): Make is_space and is_subspace bitfields.
4450 Delete unused subspace_index. All references now use the
4451 target_index field within the section structure itself.
4453 * som.c (make_unique_section): Delete unused declaration.
4454 (som_bfd_copy_private_bfd_data): New function.
4455 (som_object_setup): Allocate space for and save exec information
4456 that needs to be copied during objcopy/strip.
4457 (som_mkobject): Do not allocate space for a file header here.
4458 It is not used when only reading SOM objects.
4459 (som_prep_headers): Allocate space for and attach a file header
4460 to the output bfd. For executables, use the saved system_id
4461 value rather than trying to guess the right value. Do not abort
4462 wwhen setting file_hdr->entry* for executables.
4463 (som_begin_writing): For executables, set the exec_entry and
4465 (som_copy_private_backend_section_data): Always return a value.
4467 * libhppa.h (PA_PAGESIZE): Define.
4469 * som.c (SOM_ALIGN): Define.
4470 (som_begin_writing): If writing an executable, initialize all
4471 fields in the exec header to zero. Update fields in the exec
4472 header as sizes of loadable subspaces are computed. Carefully
4473 preserve alignments when building executables. Actually write the
4474 exec after all the fields are filled in.
4476 * Better long-filename handling. Reads SOM ABI compliant extended
4477 names, but doesn't quite write compliant extended names yet.
4478 * som.c (som_slurp_extended_name_table): Delete function. The
4479 generic code will handle things correctly.
4480 (som_slurp_armap): Seek to the beginning of the next member.
4481 (normalize): New function.
4482 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4483 name table into account when computing the file offsets in the
4484 SOM dictionary. Make sure to align to an even boundary.
4485 (som_write_armap): Initialize the checksum to zero.
4486 (ar_maxchars): Fix. Opps.
4488 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4490 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4491 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4493 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4495 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4496 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4497 * bfd-in2.h: Regenerated.
4499 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4500 this was also named trad_unix_bfd_copy_private_bfd_data.
4502 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4504 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4505 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4506 returns NULL, it is not an error. It's possible that some of
4507 these checks are not necessary (because the size can never be
4508 zero), but putting in the checks is the conservative thing to do
4509 in light of the fact that some of these malloc calls replaced
4510 unchecked alloca calls, in which a zero argument would work fine.
4512 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4514 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4515 duplicate definition.
4516 (osf_core_bfd_is_local_label): Define.
4518 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4519 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4520 failure indication, it merely means there are no relocs.
4522 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4523 after NAME, since SunOS /bin/cc can't handle it.
4525 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4527 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4528 From sukes@glue.umd.edu (Tasuki Hirata).
4530 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4532 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4533 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4534 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4536 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4538 * som.c (som_prep_for_fixups): Detect section symbols based
4539 on either the lack of private data or the symbol flags. Do not
4540 munge section symbol names anymore -- they no longer confuse GDB.
4541 (som_begin_writing): Leave space for an exec header if writing
4543 (som_slurp_symbol_table): Recognize both forms of section symbol
4544 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4545 section symbols to be the name of the section they represent.
4546 Debugging symbols begin with "L$0\001", not just "L$".
4548 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4550 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4552 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4553 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4554 and bfd_is_local_label.
4556 * targets.c: Add new entries to the bfd_target structure.
4558 * bfd.c (bfd_copy_private_bfd_data): New definition.
4560 * section.c (bfd_copy_private_section_data): New definition.
4562 * syms.c (bfd_is_local_label): New definition.
4564 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4566 * libbfd.c (bfd_generic_is_local_label): New function.
4568 * *-core.c: Provide default definitions for new functions in
4569 the target vector which all point to bfd_false.
4571 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4572 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4573 Default new vectors for copying private backend data to bfd_true.
4574 Default new vector for determining if a symbol is a local label
4575 to bfd_generic_is_local_label.
4577 * som.c (som_bfd_copy_private_section_data): New function.
4578 (som_bfd_is_local_label): New function.
4579 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4581 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4583 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4585 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4587 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4590 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4591 Indent some of them to GNU standards.
4593 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4594 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4595 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4596 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4597 Update copyright years.
4599 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4601 * som.c (som_prep_for_fixups): A relocation involving the section
4602 symbol for the *ABS* section is really a relocation involving
4604 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4605 undefined symbols. Correctly distinguish between debugger symbols
4606 and section symbols.
4608 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4609 for spaces and subspaces.
4611 * som.c (som_bfd_count_ar_symbols): Fix typo.
4613 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4614 HAS_RELOC based on the object's magic number.
4615 (make_unique_section): Delete function. BFD and its users are
4616 prepared to handle multiple sections with the same name.
4617 (setup_sections): Allocate space on the BFD's obstack to hold
4618 section names. Use bfd_make_setion_anyway rather than the
4619 obsolete make_unique_section.
4620 (som_prep_headers): Choose the correct SOM magic number based
4622 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4624 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4626 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4627 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4628 * Makefile.in, configure.in: Corresponding changes.
4630 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4632 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
4634 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4636 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4637 is always located at the start of the data section to allow
4638 recovery of the dynamic info from a stripped executable.
4639 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4642 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4644 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4645 cruft (like the #pragma alloca for AIX).
4646 In addition to that problem, the C alloca calls xmalloc, which
4647 means checking for being out of memory can't work right. The
4648 following changes remove all uses of alloca from BFD.
4649 * hosts/solaris2.h: Remove alloca cruft.
4650 * som.c: Replace alloca with a fixed size auto array.
4651 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
4652 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
4653 sunos.c: Replace alloca with malloc and appropriate error checking and
4655 * linker.c: Replace alloca with obstack_alloc.
4656 * libbfd.h: Rebuilt.
4658 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
4660 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
4663 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4665 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
4666 Elf*_Off typedefs by their expansion, the typedefs have been
4667 removed from include/elf/internal.h.
4668 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
4669 SHT_PROGBITS section.
4671 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4673 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
4675 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4677 * configure.host: Recognize i[34]86-sequent-*.
4679 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
4680 return from bfd_seek indicates an error.
4681 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
4682 TRAD_CORE_STACK_OFFSET.
4683 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
4684 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
4686 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4688 * som.[ch]: Do not include libhppa.h in som.c, instead include
4691 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
4692 include it in elf32-hppa.h.
4694 * som.c (log2): Return -1 on error rather than aborting.
4695 (setup_sections): Bubble up an error from log2.
4697 * Changes to make HP C compiler happy in both traditional
4699 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
4701 (bfd_som_set_section_attributes): Use unsigned int rather than
4702 unsigned char to avoid GNU-C extensions.
4703 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
4704 or failure rather than aborting on failure.
4706 * som.h (bfd_som_set_section_attributes): Fix prototype to match
4708 (bfd_som_attach_aux_hdr): Add prototype.
4709 (hppa_som-gen_reloc_type): Likewise.
4711 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
4712 (hppa_look_for_stubs_in_section): Do not return false on failure
4713 until rest of code is ready to handle it. Abort for now.
4715 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
4717 * bfd-in2.h: Rebuilt.
4719 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
4721 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
4722 * Makefile.in: delete an extra blank.
4723 * configure.in : Add i396os9k_vec.
4725 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
4727 * config.bfd : Add i386-os9k.
4728 * config/i386-os9k.mt : Newly add os9k target makefile.
4730 * i386os9k.c : new file to handle os9k format bfd.
4731 * Makefile.in : Handle new file i386os9k.c
4732 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
4733 * cache.c : Initialize cache_sentinel to 0.
4735 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4737 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
4738 action in case where caller specified no argument relocation.
4739 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
4740 right in the original relocation and the stub's relocation.
4742 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
4743 unused symbols argument.
4745 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
4746 than asymbol * for original target symbol. All callers changed.
4747 Set reloc->sym_ptr_ptr appropriately.
4748 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
4749 (hppa_elf_look_for_stubs_in_section): No longer need symbols
4750 argument. Use the output symbols when canonicalizing the relocs,
4751 creating them if necessary.
4753 * linker.c (_bfd_generic_link_output_symbols): Do not
4754 rebuild/clobber the output symbols if they already exist.
4756 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
4758 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
4759 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
4760 * bfd-in2.h: Rebuilt.
4762 * srec.c (hex_value): Always set to a size of 256 bytes.
4763 (srec_init): Cosmetic changes.
4765 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4767 * elf32-hppa.c: Second half of major cleanup. More comments,
4768 PARAMize and staticize rest of functions. Delete unused
4769 functions. Delete unused/unnecessary arguments to some functions.
4770 Group static vars together. Abort for bad errors until we have
4771 error code propogation working. Work on spacing and indention.
4772 Add FIXMEs for unresolved problems. Use enums rather than
4773 #defines for lots of things. Merge two functions which build
4774 linker stubs into a single function (so they can easily share a
4775 ton of common code).
4777 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
4779 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
4780 avoid depending upon right shifts of signed numbers, and to

4999 bother processing them.

5703 The sparc (and possibly other?) NLM format requires a different
5704 way to write exports, so add a write_export field to the backend
5705 data (and set it to NULL for everything but the sparc).

6981 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
6982 MY_bfd_seclet_link): Define.
6983 (MY_bfd_reloc_type_lookup): Rename from
6984 MY_reloc_howto_type_lookup.
6985 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
6986 (MY(vec)): Use JUMP_TABLE rather than listing functions.
6987 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
6988 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
6989 terms of MY, because that causes a recusive invocation of CAT when
6990 expanded within JUMP_TABLE, and ANSI compilers don't expand
6992 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
6993 MY_reloc_howto_type_lookup, and don't define in terms of MY.
6994 (MY_canonicalize_reloc): Don't define in terms of MY.
6995 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
6996 than listing functions.
