504 relocs when allocating space for relocations. Set SEC_RELOC flag
505 for any section which has relocs. Handle link_order relocs in
506 link_order loop. Use _bfd_generic_link_add_symbols_collect for
507 add_symbls entry point.

535 for first character in an extended name.
536 (_bfd_write_archive_contents): If ar_padchar == '/', then use
537 "//" as the name of the special archive member holding the
540 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
542 Support for link_order types which generate relocs in order to
543 support -Ur in the linker.
544 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
545 from call to _bfd_generic_link_add_one_symbol.
546 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
547 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
548 instead of bitsize to add_to_set call back.
549 (_bfd_generic_final_link): Account for link_order relocs when
550 allocating space for relocations. Handle them in link_order loop.
551 (_bfd_generic_reloc_link_order): New function.
552 (_bfd_default_link_order): If a reloc_link_order is seen here,

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

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

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

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

873 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
876 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
878 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
879 Elf*_Off typedefs by their expansion, the typedefs have been
880 removed from include/elf/internal.h.
881 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
882 SHT_PROGBITS section.
884 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
886 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
888 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
890 * configure.host: Recognize i[34]86-sequent-*.
892 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
893 return from bfd_seek indicates an error.
894 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
895 TRAD_CORE_STACK_OFFSET.
896 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
897 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
899 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
901 * som.[ch]: Do not include libhppa.h in som.c, instead include
904 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
905 include it in elf32-hppa.h.
907 * som.c (log2): Return -1 on error rather than aborting.

1919 The sparc (and possibly other?) NLM format requires a different
1920 way to write exports, so add a write_export field to the backend
1921 data (and set it to NULL for everything but the sparc).
