447 declaration to take boolean * rather than asymbol list.
448 (bfd_perform_slip): Change declaration to take BFD rather than
450 * coff-h8300.c (h300_reloc16_estimate): Take BFD argument rather
451 than asymbol list. Changed calls to bfd_perform_slip.

479 relocs when allocating space for relocations. Set SEC_RELOC flag
480 for any section which has relocs. Handle link_order relocs in
481 link_order loop. Use _bfd_generic_link_add_symbols_collect for
482 add_symbls entry point.
484 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
485 counting relocs. Set SEC_RELOC flag for any section which has

509 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
510 for first character in an extended name.
511 (_bfd_write_archive_contents): If ar_padchar == '/', then use
512 "//" as the name of the special archive member holding the
515 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
517 Support for link_order types which generate relocs in order to
518 support -Ur in the linker.
519 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
520 from call to _bfd_generic_link_add_one_symbol.
521 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
522 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
523 instead of bitsize to add_to_set call back.
524 (_bfd_generic_final_link): Account for link_order relocs when
525 allocating space for relocations. Handle them in link_order loop.
526 (_bfd_generic_reloc_link_order): New function.

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

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

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

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

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

851 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
853 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
854 Elf*_Off typedefs by their expansion, the typedefs have been
855 removed from include/elf/internal.h.
856 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
857 SHT_PROGBITS section.
859 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
861 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
863 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
865 * configure.host: Recognize i[34]86-sequent-*.
867 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
868 return from bfd_seek indicates an error.
869 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
870 TRAD_CORE_STACK_OFFSET.
871 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
872 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
874 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
876 * som.[ch]: Do not include libhppa.h in som.c, instead include
879 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
880 include it in elf32-hppa.h.
882 * som.c (log2): Return -1 on error rather than aborting.
883 (setup_sections): Bubble up an error from log2.
885 * Changes to make HP C compiler happy in both traditional
887 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
889 (bfd_som_set_section_attributes): Use unsigned int rather than
890 unsigned char to avoid GNU-C extensions.
891 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
892 or failure rather than aborting on failure.
894 * som.h (bfd_som_set_section_attributes): Fix prototype to match
896 (bfd_som_attach_aux_hdr): Add prototype.
897 (hppa_som-gen_reloc_type): Likewise.
899 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
900 (hppa_look_for_stubs_in_section): Do not return false on failure

903 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
905 * bfd-in2.h: Rebuilt.
907 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
909 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
910 * Makefile.in: delete an extra blank.
911 * configure.in : Add i396os9k_vec.

1894 The sparc (and possibly other?) NLM format requires a different
1895 way to write exports, so add a write_export field to the backend
1896 data (and set it to NULL for everything but the sparc).

3181 expanded within JUMP_TABLE, and ANSI compilers don't expand
3183 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
3184 MY_reloc_howto_type_lookup, and don't define in terms of MY.
