4325 required by expansions. Set s and unset h when converting a reloc
4326 from undefined to section. Change handling of PC relative relocs:
4327 if against a section, they are correct in the object file, if
4328 against an external symbol they are pcrel_offset.

4458 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4460 Support for link_order types which generate relocs in order to
4461 support -Ur in the linker.
4462 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4463 from call to _bfd_generic_link_add_one_symbol.
4464 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4465 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4466 instead of bitsize to add_to_set call back.
4467 (_bfd_generic_final_link): Account for link_order relocs when
4468 allocating space for relocations. Handle them in link_order loop.

4487 allocating space for relocations. Handle them in link_order loop.
4488 (ecoff_link_write_external): Set the storage class of a defined
4489 linker created symbol based on the section it is in. Correct
4490 bfd_link_hash_weak case to use .sc rather than .st.

4508 comparison for function symbols within executables.
4510 * som.c (bfd_section_from_som_symbol): Renamed from
4511 som_section_from_subspace_index. Pass in a native SOM symbol.
4512 For executables, iterate through the sections to find out
4513 which contains the symbol's address rather than using the
4514 symbol_info field. (symbol_info has a different meaning for
4515 dynamicly linked executables.)
4517 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4520 * som.c (som_begin_writing): Fix braino (one call to align
4521 space/subspace data was done unconditionally rather than
4522 just for executables.)
4524 * som.c (som_begin_writing): Align text in all executables to
4525 make HPUX kernel happy. Fixes strip/objcopy for shared
4528 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4530 * som.c (som_begin_writing): Account for alignment needs of
4531 subspaces too when writing executables. Never request a negative
4532 bss size. Fixes some problems with demand paged executables,
4533 still having problems with pure executables and shared executables.
4535 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4537 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4538 bfd_zalloc for rawptr, because later on we may call free, not
4541 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4542 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4543 * cisco-core.c: New file.

4550 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4552 * som.h (som_copyable_section_data_struct): New structure
4553 containing all the private section information which needs
4554 to be copied from input section to output section during
4556 (som_section_data_struct): Remove several fields now in
4557 som_copyable_section_data_struct. Make the space and
4558 subspace dictionaries be pointers (to save space when
4559 only reading objects).
4561 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4562 some references changed. Allocate a copyable data stucture if
4563 none exists. Store info into the copyable data structure.
4564 (bfd_som_set_subsection_attributes): Likewise.
4565 (som_is_space, som_is_subspace, som_is_container): New functions.
4566 Use these instead of directly accessing private data.
4567 (som_prep_headers): Allocate space and subspace headers here.
4568 Fill in some fields in the space/subspace headers from the
4570 (som_bfd_copy_private_section_data): Only copy the stuff
4571 that we really need to make objcopy and strip work. Allocate
4572 the copy_data structure for the output bfd before copying.
4574 * som.h (struct som_exec_data): New structure to hold exec
4575 info that must be preserved when running objcopy/strip.
4576 (struct somdata): Add new "exec_data" field and accessor
4577 macro. Add some comments on how the various fields are used.
4578 (som_section_data_struct): Make is_space and is_subspace bitfields.
4579 Delete unused subspace_index. All references now use the
4580 target_index field within the section structure itself.
4582 * som.c (make_unique_section): Delete unused declaration.
4583 (som_bfd_copy_private_bfd_data): New function.
4584 (som_object_setup): Allocate space for and save exec information
4585 that needs to be copied during objcopy/strip.
4586 (som_mkobject): Do not allocate space for a file header here.
4587 It is not used when only reading SOM objects.
4588 (som_prep_headers): Allocate space for and attach a file header
4589 to the output bfd. For executables, use the saved system_id
4590 value rather than trying to guess the right value. Do not abort
4591 wwhen setting file_hdr->entry* for executables.
4592 (som_begin_writing): For executables, set the exec_entry and
4594 (som_copy_private_backend_section_data): Always return a value.
4596 * libhppa.h (PA_PAGESIZE): Define.
4598 * som.c (SOM_ALIGN): Define.
4599 (som_begin_writing): If writing an executable, initialize all
4600 fields in the exec header to zero. Update fields in the exec
4601 header as sizes of loadable subspaces are computed. Carefully
4602 preserve alignments when building executables. Actually write the
4603 exec after all the fields are filled in.
4605 * Better long-filename handling. Reads SOM ABI compliant extended
4606 names, but doesn't quite write compliant extended names yet.
4607 * som.c (som_slurp_extended_name_table): Delete function. The
4608 generic code will handle things correctly.
4609 (som_slurp_armap): Seek to the beginning of the next member.
4610 (normalize): New function.
4611 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4612 name table into account when computing the file offsets in the
4613 SOM dictionary. Make sure to align to an even boundary.
4614 (som_write_armap): Initialize the checksum to zero.
4615 (ar_maxchars): Fix. Opps.

4619 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4620 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4622 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4624 * bfd-in.h (BFD_VERSION): Use @VERSION@.
4625 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
4626 * bfd-in2.h: Regenerated.
4628 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
4629 this was also named trad_unix_bfd_copy_private_bfd_data.
4631 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4633 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
4634 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
4635 returns NULL, it is not an error. It's possible that some of
4636 these checks are not necessary (because the size can never be
4637 zero), but putting in the checks is the conservative thing to do
4638 in light of the fact that some of these malloc calls replaced
4639 unchecked alloca calls, in which a zero argument would work fine.
4641 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4643 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
4644 duplicate definition.
4645 (osf_core_bfd_is_local_label): Define.
4647 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
4648 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
4649 failure indication, it merely means there are no relocs.
4651 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
4652 after NAME, since SunOS /bin/cc can't handle it.
4654 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
4656 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
4657 From sukes@glue.umd.edu (Tasuki Hirata).
4659 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4661 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
4662 all that convoluted stuff with NAME, CAT3, etc. The convoluted
4663 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
4665 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4667 * som.c (som_prep_for_fixups): Detect section symbols based
4668 on either the lack of private data or the symbol flags. Do not
4669 munge section symbol names anymore -- they no longer confuse GDB.
4670 (som_begin_writing): Leave space for an exec header if writing
4672 (som_slurp_symbol_table): Recognize both forms of section symbol
4673 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
4674 section symbols to be the name of the section they represent.
4675 Debugging symbols begin with "L$0\001", not just "L$".
4677 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4679 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
4681 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
4682 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
4683 and bfd_is_local_label.

4701 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
4702 Default new vectors for copying private backend data to bfd_true.
4703 Default new vector for determining if a symbol is a local label
4704 to bfd_generic_is_local_label.
4706 * som.c (som_bfd_copy_private_section_data): New function.
4707 (som_bfd_is_local_label): New function.
4708 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
4710 * elf32-hppa.c (hppa_elf_is_local_label): New function.
4712 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4714 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
4716 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
4719 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
4720 Indent some of them to GNU standards.
4722 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
4723 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,

4725 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
4726 Update copyright years.
4728 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4730 * som.c (som_prep_for_fixups): A relocation involving the section
4731 symbol for the *ABS* section is really a relocation involving
4733 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
4734 undefined symbols. Correctly distinguish between debugger symbols
4735 and section symbols.
4737 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
4738 for spaces and subspaces.
4740 * som.c (som_bfd_count_ar_symbols): Fix typo.
4742 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
4743 HAS_RELOC based on the object's magic number.
4744 (make_unique_section): Delete function. BFD and its users are
4745 prepared to handle multiple sections with the same name.
4746 (setup_sections): Allocate space on the BFD's obstack to hold
4747 section names. Use bfd_make_setion_anyway rather than the
4748 obsolete make_unique_section.
4749 (som_prep_headers): Choose the correct SOM magic number based
4751 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

4774 cruft (like the #pragma alloca for AIX).
4775 In addition to that problem, the C alloca calls xmalloc, which
4776 means checking for being out of memory can't work right. The
4777 following changes remove all uses of alloca from BFD.

5125 current offset in the section plus the number of bytes of padding
5126 that will actually be retained.
5127 (b_out_relax_section): If a section contains no relocations, don't
5128 bother processing them.
5129 (b_out_get_relocated_section_contents): Set reloc_done. Assert
5130 that bfd_get_section_contents returns true. Check that relocs are

5133 that reloc->addend falls between the current source offset and the
5134 raw size of the input section.
5136 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
5137 bout. Default with no version number is still bout. Support
5138 explicit i960-coff target too.

5213 Make all callers of malloc or realloc (including via obstacks)
5214 check the result for NULL. Most set bfd_error to no_memory and
5215 return in that case; a few are harder to fix, and are marked

5662 (only testing for m68k and vax at the moment); do verify that the
5663 preprocessor didn't trash the arch name inside the string version.

5832 The sparc (and possibly other?) NLM format requires a different
5833 way to write exports, so add a write_export field to the backend
5834 data (and set it to NULL for everything but the sparc).

6000 sym_filepos as well.
6001 (ecoff_get_extr): Use ifdmap instead of ifdbase.

6071 * targets.c (target_vector): Added nlm32_alpha_vec inside #ifdef
6073 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

6076 * configure.in (nlm32_alpha_vec): Set target64 to true.
6078 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
6079 different, so there is no point to providing a generic one.
6080 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
6081 in the backend accessor macros; that should no longer be possible.
6082 * targets.c (target_vector): Removed nlm32_big_generic_vec,

6971 of architectures, get the ELF EM_xxx code from the backend
6972 information. Let the generic ELF target match any EM_xxx code not
6973 matched by another ELF target. Call elf_backend_object_p to let
6974 the backend do more checks and set global information.
6975 * libelf.h (struct elf_backend_data): Added elf_machine_code and
6976 elf_backend_object_p fields.
6977 (struct bfd_elf_arch_map): Removed.

6979 * elf32-target.h, elf64-target.h: Initialize elf_machine_code
6980 field with ELF_MACHINE_CODE. Initialize elf_backend_object_p
6981 field with elf_backend_object_p (if it is defined).

6984 elf64-gen.c (ELF_MACHINE_CODE): Defined.
6985 * elf32-mips.c: Include ecoffswap.h to get ECOFF swapping
6987 (mips_elf_object_p): Set the right machine number.
6988 (mips_elf_ecoff_debug_swap): Defined.

6998 * elf32-mips.c (elf_mips_howto_table): Don't complain on overflow
6999 for R_MIPS_26. Correct overflow detection requires matching the
7000 upper four bits of the destination against the PC. From Ted Lemon
7001 <mellon@pepper.ncd.com>.
7003 * bout.c (b_out_reloc_type_lookup): Return type should point to
7005 * coff-i960.c (coff_i960_reloc_type_lookup): Likewise.
7006 * elf32-hppa.c (elf_hppa_reloc_type_lookup): Likewise.

7012 (struct elf_backend_data): Added elf_backend_ecoff_debug_swap
7013 field. Removed unused write_relocs field.
7014 * elf32-target.h: Adjusted elf_backend_data initialization
7016 * elf64-target.h: Corrected elf_backend_data initialization to
7017 fill in all fields and to set elf_64_p to 1.
7019 Mon Nov 8 18:13:14 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
