594 for first character in an extended name.
595 (_bfd_write_archive_contents): If ar_padchar == '/', then use
596 "//" as the name of the special archive member holding the
599 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
601 Support for link_order types which generate relocs in order to
602 support -Ur in the linker.
603 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
604 from call to _bfd_generic_link_add_one_symbol.
605 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
606 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
607 instead of bitsize to add_to_set call back.
608 (_bfd_generic_final_link): Account for link_order relocs when
609 allocating space for relocations. Handle them in link_order loop.
610 (_bfd_generic_reloc_link_order): New function.
611 (_bfd_default_link_order): If a reloc_link_order is seen here,
613 (_bfd_count_link_order_relocs): New function.

620 call to _bfd_generic_link_add_one_symbol.
621 (NAME(aout,final_link)): Account for link_order relocs when
622 allocating space for relocations. Handle them after handling all
624 (aout_link_reloc_link_order): New function.
625 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
626 call to _bfd_generic_link_add_one_symbol.

633 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
635 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
637 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
640 * cisco-core.c (cisco_core_file_p): Only pass one argument to
641 bfd_zmalloc. Free a pointer, not a union.

644 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
646 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
648 * som.c (bfd_section_from_som_symbol): Only to do the value
649 comparison for function symbols within executables.
651 * som.c (bfd_section_from_som_symbol): Renamed from
652 som_section_from_subspace_index. Pass in a native SOM symbol.
653 For executables, iterate through the sections to find out
654 which contains the symbol's address rather than using the
655 symbol_info field. (symbol_info has a different meaning for
656 dynamicly linked executables.)
658 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
661 * som.c (som_begin_writing): Fix braino (one call to align
662 space/subspace data was done unconditionally rather than
663 just for executables.)
665 * som.c (som_begin_writing): Align text in all executables to
666 make HPUX kernel happy. Fixes strip/objcopy for shared
669 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
671 * som.c (som_begin_writing): Account for alignment needs of
672 subspaces too when writing executables. Never request a negative
673 bss size. Fixes some problems with demand paged executables,
674 still having problems with pure executables and shared executables.
676 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
678 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
679 bfd_zalloc for rawptr, because later on we may call free, not
682 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
683 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
684 * cisco-core.c: New file.
685 * Makefile.in: Change accordingly.
686 * configure.in: Recognize cisco_core_vec.
687 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
688 * targets.c: Add cisco_core_vec.
689 * bfd-in2.h: Rebuilt.
691 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
693 * som.h (som_copyable_section_data_struct): New structure
694 containing all the private section information which needs
695 to be copied from input section to output section during
697 (som_section_data_struct): Remove several fields now in
698 som_copyable_section_data_struct. Make the space and
699 subspace dictionaries be pointers (to save space when
700 only reading objects).
702 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
703 some references changed. Allocate a copyable data stucture if
704 none exists. Store info into the copyable data structure.
705 (bfd_som_set_subsection_attributes): Likewise.
706 (som_is_space, som_is_subspace, som_is_container): New functions.
707 Use these instead of directly accessing private data.
708 (som_prep_headers): Allocate space and subspace headers here.
709 Fill in some fields in the space/subspace headers from the
711 (som_bfd_copy_private_section_data): Only copy the stuff
712 that we really need to make objcopy and strip work. Allocate
713 the copy_data structure for the output bfd before copying.
715 * som.h (struct som_exec_data): New structure to hold exec
716 info that must be preserved when running objcopy/strip.
717 (struct somdata): Add new "exec_data" field and accessor
718 macro. Add some comments on how the various fields are used.
719 (som_section_data_struct): Make is_space and is_subspace bitfields.
720 Delete unused subspace_index. All references now use the
721 target_index field within the section structure itself.
723 * som.c (make_unique_section): Delete unused declaration.
724 (som_bfd_copy_private_bfd_data): New function.
725 (som_object_setup): Allocate space for and save exec information
726 that needs to be copied during objcopy/strip.
727 (som_mkobject): Do not allocate space for a file header here.
728 It is not used when only reading SOM objects.
729 (som_prep_headers): Allocate space for and attach a file header
730 to the output bfd. For executables, use the saved system_id
731 value rather than trying to guess the right value. Do not abort
732 wwhen setting file_hdr->entry* for executables.
733 (som_begin_writing): For executables, set the exec_entry and
735 (som_copy_private_backend_section_data): Always return a value.
737 * libhppa.h (PA_PAGESIZE): Define.
739 * som.c (SOM_ALIGN): Define.
740 (som_begin_writing): If writing an executable, initialize all
741 fields in the exec header to zero. Update fields in the exec
742 header as sizes of loadable subspaces are computed. Carefully
743 preserve alignments when building executables. Actually write the
744 exec after all the fields are filled in.
746 * Better long-filename handling. Reads SOM ABI compliant extended
747 names, but doesn't quite write compliant extended names yet.
748 * som.c (som_slurp_extended_name_table): Delete function. The
749 generic code will handle things correctly.
750 (som_slurp_armap): Seek to the beginning of the next member.
751 (normalize): New function.
752 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
753 name table into account when computing the file offsets in the
754 SOM dictionary. Make sure to align to an even boundary.
755 (som_write_armap): Initialize the checksum to zero.
756 (ar_maxchars): Fix. Opps.
758 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
760 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
761 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
763 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
765 * bfd-in.h (BFD_VERSION): Use @VERSION@.
766 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
767 * bfd-in2.h: Regenerated.
769 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
770 this was also named trad_unix_bfd_copy_private_bfd_data.
772 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
774 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
775 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
776 returns NULL, it is not an error. It's possible that some of
777 these checks are not necessary (because the size can never be
778 zero), but putting in the checks is the conservative thing to do
779 in light of the fact that some of these malloc calls replaced
780 unchecked alloca calls, in which a zero argument would work fine.
782 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
784 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
785 duplicate definition.
786 (osf_core_bfd_is_local_label): Define.
788 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
789 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
790 failure indication, it merely means there are no relocs.
792 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
793 after NAME, since SunOS /bin/cc can't handle it.
795 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
797 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
798 From sukes@glue.umd.edu (Tasuki Hirata).
800 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
802 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
803 all that convoluted stuff with NAME, CAT3, etc. The convoluted
804 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
806 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
808 * som.c (som_prep_for_fixups): Detect section symbols based
809 on either the lack of private data or the symbol flags. Do not
810 munge section symbol names anymore -- they no longer confuse GDB.
811 (som_begin_writing): Leave space for an exec header if writing
813 (som_slurp_symbol_table): Recognize both forms of section symbol
814 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
815 section symbols to be the name of the section they represent.
816 Debugging symbols begin with "L$0\001", not just "L$".
818 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
820 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
822 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
823 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
824 and bfd_is_local_label.
826 * targets.c: Add new entries to the bfd_target structure.
828 * bfd.c (bfd_copy_private_bfd_data): New definition.

842 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
843 Default new vectors for copying private backend data to bfd_true.
844 Default new vector for determining if a symbol is a local label
845 to bfd_generic_is_local_label.
847 * som.c (som_bfd_copy_private_section_data): New function.
848 (som_bfd_is_local_label): New function.
849 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
851 * elf32-hppa.c (hppa_elf_is_local_label): New function.
853 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
855 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
857 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
860 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
861 Indent some of them to GNU standards.
863 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
864 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
865 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
866 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
867 Update copyright years.
869 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
871 * som.c (som_prep_for_fixups): A relocation involving the section
872 symbol for the *ABS* section is really a relocation involving
874 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
875 undefined symbols. Correctly distinguish between debugger symbols
878 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
879 for spaces and subspaces.

884 HAS_RELOC based on the object's magic number.
885 (make_unique_section): Delete function. BFD and its users are
886 prepared to handle multiple sections with the same name.
887 (setup_sections): Allocate space on the BFD's obstack to hold
888 section names. Use bfd_make_setion_anyway rather than the
889 obsolete make_unique_section.
890 (som_prep_headers): Choose the correct SOM magic number based
892 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
894 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)

916 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
917 cruft (like the #pragma alloca for AIX).
918 In addition to that problem, the C alloca calls xmalloc, which
919 means checking for being out of memory can't work right. The
920 following changes remove all uses of alloca from BFD.

1272 that will actually be retained.
1273 (b_out_relax_section): If a section contains no relocations, don't
1274 bother processing them.
1275 (b_out_get_relocated_section_contents): Set reloc_done. Assert

1359 Make all callers of malloc or realloc (including via obstacks)
1360 check the result for NULL. Most set bfd_error to no_memory and
1361 return in that case; a few are harder to fix, and are marked

1365 hppa_elf_build_long_branch_stub): Check bfd_make_empty_symbol return.

1808 (only testing for m68k and vax at the moment); do verify that the
1809 preprocessor didn't trash the arch name inside the string version.

1951 undefined, look it up in the linker hash table.
1953 * aoutx.h (translate_symbol_table): The string index 0 has a

1978 The sparc (and possibly other?) NLM format requires a different
1979 way to write exports, so add a write_export field to the backend
1980 data (and set it to NULL for everything but the sparc).

2146 sym_filepos as well.
2147 (ecoff_get_extr): Use ifdmap instead of ifdbase.

2219 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

2222 * configure.in (nlm32_alpha_vec): Set target64 to true.
2224 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
2225 different, so there is no point to providing a generic one.
2226 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
2227 in the backend accessor macros; that should no longer be possible.
2228 * targets.c (target_vector): Removed nlm32_big_generic_vec,
