498 relocs when allocating space for relocations. Set SEC_RELOC flag
499 for any section which has relocs. Handle link_order relocs in
500 link_order loop. Use _bfd_generic_link_add_symbols_collect for
501 add_symbls entry point.

528 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
529 for first character in an extended name.
530 (_bfd_write_archive_contents): If ar_padchar == '/', then use
531 "//" as the name of the special archive member holding the
534 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
536 Support for link_order types which generate relocs in order to
537 support -Ur in the linker.

539 from call to _bfd_generic_link_add_one_symbol.
540 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
541 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
542 instead of bitsize to add_to_set call back.
543 (_bfd_generic_final_link): Account for link_order relocs when
544 allocating space for relocations. Handle them in link_order loop.
545 (_bfd_generic_reloc_link_order): New function.

576 bfd_zmalloc. Free a pointer, not a union.
577 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
579 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
581 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
583 * som.c (bfd_section_from_som_symbol): Only to do the value
584 comparison for function symbols within executables.
586 * som.c (bfd_section_from_som_symbol): Renamed from
587 som_section_from_subspace_index. Pass in a native SOM symbol.
588 For executables, iterate through the sections to find out
589 which contains the symbol's address rather than using the
590 symbol_info field. (symbol_info has a different meaning for
591 dynamicly linked executables.)
593 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
596 * som.c (som_begin_writing): Fix braino (one call to align
597 space/subspace data was done unconditionally rather than
598 just for executables.)
600 * som.c (som_begin_writing): Align text in all executables to
601 make HPUX kernel happy. Fixes strip/objcopy for shared
604 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
606 * som.c (som_begin_writing): Account for alignment needs of
607 subspaces too when writing executables. Never request a negative
608 bss size. Fixes some problems with demand paged executables,
609 still having problems with pure executables and shared executables.
611 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
613 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
614 bfd_zalloc for rawptr, because later on we may call free, not
617 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
618 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
619 * cisco-core.c: New file.

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

761 * targets.c: Add new entries to the bfd_target structure.
763 * bfd.c (bfd_copy_private_bfd_data): New definition.

773 * *-core.c: Provide default definitions for new functions in
774 the target vector which all point to bfd_false.
776 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
777 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
778 Default new vectors for copying private backend data to bfd_true.
779 Default new vector for determining if a symbol is a local label
780 to bfd_generic_is_local_label.
782 * som.c (som_bfd_copy_private_section_data): New function.
783 (som_bfd_is_local_label): New function.
784 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
786 * elf32-hppa.c (hppa_elf_is_local_label): New function.
788 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
790 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
792 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
795 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
796 Indent some of them to GNU standards.
798 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
799 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
800 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
801 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
802 Update copyright years.
804 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
806 * som.c (som_prep_for_fixups): A relocation involving the section
807 symbol for the *ABS* section is really a relocation involving
809 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
810 undefined symbols. Correctly distinguish between debugger symbols
813 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
814 for spaces and subspaces.
816 * som.c (som_bfd_count_ar_symbols): Fix typo.

819 HAS_RELOC based on the object's magic number.
820 (make_unique_section): Delete function. BFD and its users are
821 prepared to handle multiple sections with the same name.
822 (setup_sections): Allocate space on the BFD's obstack to hold
823 section names. Use bfd_make_setion_anyway rather than the
824 obsolete make_unique_section.
825 (som_prep_headers): Choose the correct SOM magic number based
827 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
829 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
831 * elf32-ppc.c: Renamed from elf32-powerpc.c.

841 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
843 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info

849 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
851 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
852 cruft (like the #pragma alloca for AIX).
853 In addition to that problem, the C alloca calls xmalloc, which
854 means checking for being out of memory can't work right. The
855 following changes remove all uses of alloca from BFD.
856 * hosts/solaris2.h: Remove alloca cruft.
857 * som.c: Replace alloca with a fixed size auto array.

870 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
872 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
873 Elf*_Off typedefs by their expansion, the typedefs have been
874 removed from include/elf/internal.h.
875 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
876 SHT_PROGBITS section.
878 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
880 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
882 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
884 * configure.host: Recognize i[34]86-sequent-*.
886 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
887 return from bfd_seek indicates an error.
888 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
889 TRAD_CORE_STACK_OFFSET.
890 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
891 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
893 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
895 * som.[ch]: Do not include libhppa.h in som.c, instead include
898 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
899 include it in elf32-hppa.h.
901 * som.c (log2): Return -1 on error rather than aborting.
902 (setup_sections): Bubble up an error from log2.
904 * Changes to make HP C compiler happy in both traditional
906 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
908 (bfd_som_set_section_attributes): Use unsigned int rather than
909 unsigned char to avoid GNU-C extensions.
910 (bfd_som_attach_aux_hdr): Return a boolean to indicate success

1913 The sparc (and possibly other?) NLM format requires a different
1914 way to write exports, so add a write_export field to the backend
1915 data (and set it to NULL for everything but the sparc).
