4321 * aoutx.h (NAME(aout,find_nearest_line)): The caller expects
4322 functionname_ptr to be set to a symbol name, so prepend
4323 symbol_leading_char.

4397 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4399 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
4400 reloc, used in embedded PIC code.
4401 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

4420 _bfd_generic_link_add_symbols but also collect constructors and
4421 destructors by name as collect2 does.

4440 extended name table.
4442 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4444 Support for link_order types which generate relocs in order to
4445 support -Ur in the linker.
4446 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4447 from call to _bfd_generic_link_add_one_symbol.
4448 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4449 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4450 instead of bitsize to add_to_set call back.
4451 (_bfd_generic_final_link): Account for link_order relocs when
4452 allocating space for relocations. Handle them in link_order loop.
4453 (_bfd_generic_reloc_link_order): New function.

4471 allocating space for relocations. Handle them in link_order loop.
4472 (ecoff_link_write_external): Set the storage class of a defined
4473 linker created symbol based on the section it is in. Correct
4474 bfd_link_hash_weak case to use .sc rather than .st.

4487 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4489 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4491 * som.c (bfd_section_from_som_symbol): Only to do the value
4492 comparison for function symbols within executables.
4494 * som.c (bfd_section_from_som_symbol): Renamed from
4495 som_section_from_subspace_index. Pass in a native SOM symbol.
4496 For executables, iterate through the sections to find out
4497 which contains the symbol's address rather than using the
4498 symbol_info field. (symbol_info has a different meaning for
4499 dynamicly linked executables.)
4501 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4504 * som.c (som_begin_writing): Fix braino (one call to align
4505 space/subspace data was done unconditionally rather than
4506 just for executables.)
4508 * som.c (som_begin_writing): Align text in all executables to
4509 make HPUX kernel happy. Fixes strip/objcopy for shared
4512 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4514 * som.c (som_begin_writing): Account for alignment needs of
4515 subspaces too when writing executables. Never request a negative
4516 bss size. Fixes some problems with demand paged executables,
4517 still having problems with pure executables and shared executables.
4519 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4521 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4522 bfd_zalloc for rawptr, because later on we may call free, not
4525 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4526 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4527 * cisco-core.c: New file.
4528 * Makefile.in: Change accordingly.
4529 * configure.in: Recognize cisco_core_vec.
4530 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4531 * targets.c: Add cisco_core_vec.
4532 * bfd-in2.h: Rebuilt.
4534 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4536 * som.h (som_copyable_section_data_struct): New structure
4537 containing all the private section information which needs
4538 to be copied from input section to output section during
4540 (som_section_data_struct): Remove several fields now in
4541 som_copyable_section_data_struct. Make the space and
4542 subspace dictionaries be pointers (to save space when
4543 only reading objects).
4545 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4546 some references changed. Allocate a copyable data stucture if
4547 none exists. Store info into the copyable data structure.
4548 (bfd_som_set_subsection_attributes): Likewise.
4549 (som_is_space, som_is_subspace, som_is_container): New functions.
4550 Use these instead of directly accessing private data.
4551 (som_prep_headers): Allocate space and subspace headers here.
4552 Fill in some fields in the space/subspace headers from the
4554 (som_bfd_copy_private_section_data): Only copy the stuff
4555 that we really need to make objcopy and strip work. Allocate
4556 the copy_data structure for the output bfd before copying.
4558 * som.h (struct som_exec_data): New structure to hold exec
4559 info that must be preserved when running objcopy/strip.
4560 (struct somdata): Add new "exec_data" field and accessor
4561 macro. Add some comments on how the various fields are used.
4562 (som_section_data_struct): Make is_space and is_subspace bitfields.
4563 Delete unused subspace_index. All references now use the
4564 target_index field within the section structure itself.
4566 * som.c (make_unique_section): Delete unused declaration.
4567 (som_bfd_copy_private_bfd_data): New function.
4568 (som_object_setup): Allocate space for and save exec information
4569 that needs to be copied during objcopy/strip.
4570 (som_mkobject): Do not allocate space for a file header here.
4571 It is not used when only reading SOM objects.
4572 (som_prep_headers): Allocate space for and attach a file header
4573 to the output bfd. For executables, use the saved system_id
4574 value rather than trying to guess the right value. Do not abort
4575 wwhen setting file_hdr->entry* for executables.
4576 (som_begin_writing): For executables, set the exec_entry and
4578 (som_copy_private_backend_section_data): Always return a value.
4580 * libhppa.h (PA_PAGESIZE): Define.
4582 * som.c (SOM_ALIGN): Define.
4583 (som_begin_writing): If writing an executable, initialize all
4584 fields in the exec header to zero. Update fields in the exec
4585 header as sizes of loadable subspaces are computed. Carefully
4586 preserve alignments when building executables. Actually write the
4587 exec after all the fields are filled in.
4589 * Better long-filename handling. Reads SOM ABI compliant extended
4590 names, but doesn't quite write compliant extended names yet.
4591 * som.c (som_slurp_extended_name_table): Delete function. The
4592 generic code will handle things correctly.
4593 (som_slurp_armap): Seek to the beginning of the next member.
4594 (normalize): New function.
4595 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4596 name table into account when computing the file offsets in the
4597 SOM dictionary. Make sure to align to an even boundary.
4598 (som_write_armap): Initialize the checksum to zero.
4599 (ar_maxchars): Fix. Opps.
4601 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4603 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4604 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4606 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4608 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4609 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4610 * bfd-in2.h: Regenerated.
4612 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4613 this was also named trad_unix_bfd_copy_private_bfd_data.
4615 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4617 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4618 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4619 returns NULL, it is not an error. It's possible that some of
4620 these checks are not necessary (because the size can never be
4621 zero), but putting in the checks is the conservative thing to do
4622 in light of the fact that some of these malloc calls replaced
4623 unchecked alloca calls, in which a zero argument would work fine.
4625 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4627 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4628 duplicate definition.
4629 (osf_core_bfd_is_local_label): Define.
4631 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4632 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4633 failure indication, it merely means there are no relocs.
4635 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4636 after NAME, since SunOS /bin/cc can't handle it.
4638 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4640 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4641 From sukes@glue.umd.edu (Tasuki Hirata).
4643 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4645 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4646 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4647 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4649 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4651 * som.c (som_prep_for_fixups): Detect section symbols based
4652 on either the lack of private data or the symbol flags. Do not
4653 munge section symbol names anymore -- they no longer confuse GDB.
4654 (som_begin_writing): Leave space for an exec header if writing
4656 (som_slurp_symbol_table): Recognize both forms of section symbol
4657 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4658 section symbols to be the name of the section they represent.
4659 Debugging symbols begin with "L$0\001", not just "L$".
4661 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4663 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4665 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4666 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4667 and bfd_is_local_label.
4669 * targets.c: Add new entries to the bfd_target structure.
4671 * bfd.c (bfd_copy_private_bfd_data): New definition.
4673 * section.c (bfd_copy_private_section_data): New definition.
4675 * syms.c (bfd_is_local_label): New definition.
4677 * libbfd-in.h (bfd_generic_is_local_label): Declare.
4679 * libbfd.c (bfd_generic_is_local_label): New function.
4681 * *-core.c: Provide default definitions for new functions in
4682 the target vector which all point to bfd_false.
4684 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
4685 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4686 Default new vectors for copying private backend data to bfd_true.
4687 Default new vector for determining if a symbol is a local label
4688 to bfd_generic_is_local_label.
4690 * som.c (som_bfd_copy_private_section_data): New function.
4691 (som_bfd_is_local_label): New function.
4692 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4694 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4696 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4698 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4700 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4703 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4704 Indent some of them to GNU standards.
4706 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4707 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
4708 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
4709 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4710 Update copyright years.
4712 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4714 * som.c (som_prep_for_fixups): A relocation involving the section
4715 symbol for the *ABS* section is really a relocation involving
4717 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4718 undefined symbols. Correctly distinguish between debugger symbols
4719 and section symbols.
4721 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4722 for spaces and subspaces.
4724 * som.c (som_bfd_count_ar_symbols): Fix typo.
4726 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4727 HAS_RELOC based on the object's magic number.
4728 (make_unique_section): Delete function. BFD and its users are
4729 prepared to handle multiple sections with the same name.
4730 (setup_sections): Allocate space on the BFD's obstack to hold
4731 section names. Use bfd_make_setion_anyway rather than the
4732 obsolete make_unique_section.
4733 (som_prep_headers): Choose the correct SOM magic number based
4735 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
4737 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
4739 * elf32-ppc.c: Renamed from elf32-powerpc.c.
4740 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
4741 * Makefile.in, configure.in: Corresponding changes.
4743 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4745 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
4747 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
4749 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
4750 is always located at the start of the data section to allow
4751 recovery of the dynamic info from a stripped executable.
4752 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
4755 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4757 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
4758 cruft (like the #pragma alloca for AIX).
4759 In addition to that problem, the C alloca calls xmalloc, which
4760 means checking for being out of memory can't work right. The

5112 bother processing them.
5113 (b_out_get_relocated_section_contents): Set reloc_done. Assert

5117 that reloc->addend falls between the current source offset and the
5118 raw size of the input section.

5816 The sparc (and possibly other?) NLM format requires a different
5817 way to write exports, so add a write_export field to the backend
5818 data (and set it to NULL for everything but the sparc).

5984 sym_filepos as well.
5985 (ecoff_get_extr): Use ifdmap instead of ifdbase.

6057 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

6062 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
6063 different, so there is no point to providing a generic one.
6064 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
6065 in the backend accessor macros; that should no longer be possible.
