560 for first character in an extended name.
561 (_bfd_write_archive_contents): If ar_padchar == '/', then use
562 "//" as the name of the special archive member holding the
565 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
567 Support for link_order types which generate relocs in order to
568 support -Ur in the linker.
569 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
570 from call to _bfd_generic_link_add_one_symbol.
571 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
572 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
573 instead of bitsize to add_to_set call back.
574 (_bfd_generic_final_link): Account for link_order relocs when
575 allocating space for relocations. Handle them in link_order loop.
576 (_bfd_generic_reloc_link_order): New function.

610 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
612 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
614 * som.c (bfd_section_from_som_symbol): Only to do the value
615 comparison for function symbols within executables.
617 * som.c (bfd_section_from_som_symbol): Renamed from
618 som_section_from_subspace_index. Pass in a native SOM symbol.
619 For executables, iterate through the sections to find out
620 which contains the symbol's address rather than using the
621 symbol_info field. (symbol_info has a different meaning for
622 dynamicly linked executables.)
624 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
627 * som.c (som_begin_writing): Fix braino (one call to align
628 space/subspace data was done unconditionally rather than
629 just for executables.)
631 * som.c (som_begin_writing): Align text in all executables to
632 make HPUX kernel happy. Fixes strip/objcopy for shared
635 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
637 * som.c (som_begin_writing): Account for alignment needs of
638 subspaces too when writing executables. Never request a negative
639 bss size. Fixes some problems with demand paged executables,
640 still having problems with pure executables and shared executables.
642 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
644 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
645 bfd_zalloc for rawptr, because later on we may call free, not
648 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.

655 * bfd-in2.h: Rebuilt.
657 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
659 * som.h (som_copyable_section_data_struct): New structure
660 containing all the private section information which needs
661 to be copied from input section to output section during
663 (som_section_data_struct): Remove several fields now in
664 som_copyable_section_data_struct. Make the space and
665 subspace dictionaries be pointers (to save space when
666 only reading objects).
668 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
669 some references changed. Allocate a copyable data stucture if
670 none exists. Store info into the copyable data structure.
671 (bfd_som_set_subsection_attributes): Likewise.
672 (som_is_space, som_is_subspace, som_is_container): New functions.
673 Use these instead of directly accessing private data.
674 (som_prep_headers): Allocate space and subspace headers here.
675 Fill in some fields in the space/subspace headers from the
677 (som_bfd_copy_private_section_data): Only copy the stuff
678 that we really need to make objcopy and strip work. Allocate
679 the copy_data structure for the output bfd before copying.
681 * som.h (struct som_exec_data): New structure to hold exec
682 info that must be preserved when running objcopy/strip.
683 (struct somdata): Add new "exec_data" field and accessor
684 macro. Add some comments on how the various fields are used.
685 (som_section_data_struct): Make is_space and is_subspace bitfields.
686 Delete unused subspace_index. All references now use the
687 target_index field within the section structure itself.
689 * som.c (make_unique_section): Delete unused declaration.
690 (som_bfd_copy_private_bfd_data): New function.
691 (som_object_setup): Allocate space for and save exec information
692 that needs to be copied during objcopy/strip.
693 (som_mkobject): Do not allocate space for a file header here.
694 It is not used when only reading SOM objects.
695 (som_prep_headers): Allocate space for and attach a file header
696 to the output bfd. For executables, use the saved system_id
697 value rather than trying to guess the right value. Do not abort
698 wwhen setting file_hdr->entry* for executables.
699 (som_begin_writing): For executables, set the exec_entry and
701 (som_copy_private_backend_section_data): Always return a value.
703 * libhppa.h (PA_PAGESIZE): Define.
705 * som.c (SOM_ALIGN): Define.
706 (som_begin_writing): If writing an executable, initialize all
707 fields in the exec header to zero. Update fields in the exec
708 header as sizes of loadable subspaces are computed. Carefully
709 preserve alignments when building executables. Actually write the
710 exec after all the fields are filled in.
712 * Better long-filename handling. Reads SOM ABI compliant extended
713 names, but doesn't quite write compliant extended names yet.
714 * som.c (som_slurp_extended_name_table): Delete function. The
715 generic code will handle things correctly.
716 (som_slurp_armap): Seek to the beginning of the next member.
717 (normalize): New function.
718 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
719 name table into account when computing the file offsets in the
720 SOM dictionary. Make sure to align to an even boundary.
721 (som_write_armap): Initialize the checksum to zero.
722 (ar_maxchars): Fix. Opps.
724 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
726 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
727 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
729 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
731 * bfd-in.h (BFD_VERSION): Use @VERSION@.
732 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
733 * bfd-in2.h: Regenerated.
735 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
736 this was also named trad_unix_bfd_copy_private_bfd_data.
738 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
740 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
741 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
742 returns NULL, it is not an error. It's possible that some of
743 these checks are not necessary (because the size can never be
744 zero), but putting in the checks is the conservative thing to do
745 in light of the fact that some of these malloc calls replaced
746 unchecked alloca calls, in which a zero argument would work fine.
748 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
750 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
751 duplicate definition.
752 (osf_core_bfd_is_local_label): Define.
754 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
755 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
756 failure indication, it merely means there are no relocs.
758 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
759 after NAME, since SunOS /bin/cc can't handle it.
761 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
763 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
764 From sukes@glue.umd.edu (Tasuki Hirata).
766 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
768 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
769 all that convoluted stuff with NAME, CAT3, etc. The convoluted
770 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
772 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
774 * som.c (som_prep_for_fixups): Detect section symbols based
775 on either the lack of private data or the symbol flags. Do not
776 munge section symbol names anymore -- they no longer confuse GDB.
777 (som_begin_writing): Leave space for an exec header if writing
779 (som_slurp_symbol_table): Recognize both forms of section symbol
780 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
781 section symbols to be the name of the section they represent.
782 Debugging symbols begin with "L$0\001", not just "L$".
784 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
786 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
788 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
789 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
790 and bfd_is_local_label.
792 * targets.c: Add new entries to the bfd_target structure.
794 * bfd.c (bfd_copy_private_bfd_data): New definition.

804 * *-core.c: Provide default definitions for new functions in
805 the target vector which all point to bfd_false.
807 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
808 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
809 Default new vectors for copying private backend data to bfd_true.
810 Default new vector for determining if a symbol is a local label
811 to bfd_generic_is_local_label.
813 * som.c (som_bfd_copy_private_section_data): New function.
814 (som_bfd_is_local_label): New function.
815 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
817 * elf32-hppa.c (hppa_elf_is_local_label): New function.
819 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
821 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
823 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
826 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
827 Indent some of them to GNU standards.
829 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
830 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
831 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
832 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
833 Update copyright years.
835 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
837 * som.c (som_prep_for_fixups): A relocation involving the section
838 symbol for the *ABS* section is really a relocation involving
840 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
841 undefined symbols. Correctly distinguish between debugger symbols
844 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
845 for spaces and subspaces.
847 * som.c (som_bfd_count_ar_symbols): Fix typo.
849 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
850 HAS_RELOC based on the object's magic number.
851 (make_unique_section): Delete function. BFD and its users are
852 prepared to handle multiple sections with the same name.
853 (setup_sections): Allocate space on the BFD's obstack to hold
854 section names. Use bfd_make_setion_anyway rather than the
855 obsolete make_unique_section.
856 (som_prep_headers): Choose the correct SOM magic number based
858 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
860 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
862 * elf32-ppc.c: Renamed from elf32-powerpc.c.

872 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
874 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
875 is always located at the start of the data section to allow
876 recovery of the dynamic info from a stripped executable.
877 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
880 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
882 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
883 cruft (like the #pragma alloca for AIX).
884 In addition to that problem, the C alloca calls xmalloc, which
885 means checking for being out of memory can't work right. The
886 following changes remove all uses of alloca from BFD.
887 * hosts/solaris2.h: Remove alloca cruft.
888 * som.c: Replace alloca with a fixed size auto array.
889 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

898 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
901 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
903 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
904 Elf*_Off typedefs by their expansion, the typedefs have been
905 removed from include/elf/internal.h.
906 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
907 SHT_PROGBITS section.

1240 bother processing them.

1944 The sparc (and possibly other?) NLM format requires a different
1945 way to write exports, so add a write_export field to the backend
1946 data (and set it to NULL for everything but the sparc).
