2617 in asymbol udata field.
2619 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2621 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
2622 reloc, used in embedded PIC code.
2623 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

2630 link_order loop. Use _bfd_generic_link_add_symbols_collect for
2631 add_symbls entry point.
2633 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
2634 counting relocs. Set SEC_RELOC flag for any section which has

2639 * linker.c (_bfd_generic_link_add_symbols): Just call
2640 generic_link_add_symbols.
2641 (_bfd_generic_link_add_symbols_collect): New function, like
2642 _bfd_generic_link_add_symbols but also collect constructors and
2643 destructors by name as collect2 does.
2644 (generic_link_add_symbols): New function, like old
2645 _bfd_generic_link_add_symbols but with collect argument.
2646 (generic_link_add_object_symbols): Take collect argument.

2658 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
2659 for first character in an extended name.
2660 (_bfd_write_archive_contents): If ar_padchar == '/', then use
2661 "//" as the name of the special archive member holding the
2662 extended name table.
2664 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2666 Support for link_order types which generate relocs in order to
2667 support -Ur in the linker.
2668 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2669 from call to _bfd_generic_link_add_one_symbol.
2670 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2671 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2672 instead of bitsize to add_to_set call back.
2673 (_bfd_generic_final_link): Account for link_order relocs when
2674 allocating space for relocations. Handle them in link_order loop.
2675 (_bfd_generic_reloc_link_order): New function.
2676 (_bfd_default_link_order): If a reloc_link_order is seen here,
2678 (_bfd_count_link_order_relocs): New function.
2679 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
2680 argument from declaration.
2681 (_bfd_generic_reloc_link_order): Declare.

2691 call to _bfd_generic_link_add_one_symbol.
2692 (ecoff_bfd_final_link): Account for link_order relocs when
2693 allocating space for relocations. Handle them in link_order loop.
2694 (ecoff_link_write_external): Set the storage class of a defined
2695 linker created symbol based on the section it is in. Correct
2696 bfd_link_hash_weak case to use .sc rather than .st.
2697 (ecoff_reloc_link_order): New function.
2698 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2700 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2705 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2706 bfd_zmalloc. Free a pointer, not a union.
2707 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2709 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2711 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2713 * som.c (bfd_section_from_som_symbol): Only to do the value
2714 comparison for function symbols within executables.
2716 * som.c (bfd_section_from_som_symbol): Renamed from
2717 som_section_from_subspace_index. Pass in a native SOM symbol.
2718 For executables, iterate through the sections to find out
2719 which contains the symbol's address rather than using the
2720 symbol_info field. (symbol_info has a different meaning for
2721 dynamicly linked executables.)
2723 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2726 * som.c (som_begin_writing): Fix braino (one call to align
2727 space/subspace data was done unconditionally rather than
2728 just for executables.)
2730 * som.c (som_begin_writing): Align text in all executables to
2731 make HPUX kernel happy. Fixes strip/objcopy for shared
2734 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2736 * som.c (som_begin_writing): Account for alignment needs of
2737 subspaces too when writing executables. Never request a negative
2738 bss size. Fixes some problems with demand paged executables,
2739 still having problems with pure executables and shared executables.
2741 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2743 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2744 bfd_zalloc for rawptr, because later on we may call free, not
2747 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2748 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2749 * cisco-core.c: New file.
2750 * Makefile.in: Change accordingly.
2751 * configure.in: Recognize cisco_core_vec.
2752 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2753 * targets.c: Add cisco_core_vec.
2754 * bfd-in2.h: Rebuilt.
2756 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2758 * som.h (som_copyable_section_data_struct): New structure
2759 containing all the private section information which needs
2760 to be copied from input section to output section during
2762 (som_section_data_struct): Remove several fields now in
2763 som_copyable_section_data_struct. Make the space and
2764 subspace dictionaries be pointers (to save space when
2765 only reading objects).
2767 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2768 some references changed. Allocate a copyable data stucture if
2769 none exists. Store info into the copyable data structure.
2770 (bfd_som_set_subsection_attributes): Likewise.
2771 (som_is_space, som_is_subspace, som_is_container): New functions.
2772 Use these instead of directly accessing private data.
2773 (som_prep_headers): Allocate space and subspace headers here.
2774 Fill in some fields in the space/subspace headers from the
2776 (som_bfd_copy_private_section_data): Only copy the stuff
2777 that we really need to make objcopy and strip work. Allocate
2778 the copy_data structure for the output bfd before copying.
2780 * som.h (struct som_exec_data): New structure to hold exec
2781 info that must be preserved when running objcopy/strip.
2782 (struct somdata): Add new "exec_data" field and accessor
2783 macro. Add some comments on how the various fields are used.
2784 (som_section_data_struct): Make is_space and is_subspace bitfields.
2785 Delete unused subspace_index. All references now use the
2786 target_index field within the section structure itself.
2788 * som.c (make_unique_section): Delete unused declaration.
2789 (som_bfd_copy_private_bfd_data): New function.
2790 (som_object_setup): Allocate space for and save exec information
2791 that needs to be copied during objcopy/strip.
2792 (som_mkobject): Do not allocate space for a file header here.
2793 It is not used when only reading SOM objects.
2794 (som_prep_headers): Allocate space for and attach a file header
2795 to the output bfd. For executables, use the saved system_id
2796 value rather than trying to guess the right value. Do not abort
2797 wwhen setting file_hdr->entry* for executables.
2798 (som_begin_writing): For executables, set the exec_entry and
2800 (som_copy_private_backend_section_data): Always return a value.
2802 * libhppa.h (PA_PAGESIZE): Define.
2804 * som.c (SOM_ALIGN): Define.
2805 (som_begin_writing): If writing an executable, initialize all
2806 fields in the exec header to zero. Update fields in the exec
2807 header as sizes of loadable subspaces are computed. Carefully
2808 preserve alignments when building executables. Actually write the
2809 exec after all the fields are filled in.
2811 * Better long-filename handling. Reads SOM ABI compliant extended
2812 names, but doesn't quite write compliant extended names yet.
2813 * som.c (som_slurp_extended_name_table): Delete function. The
2814 generic code will handle things correctly.
2815 (som_slurp_armap): Seek to the beginning of the next member.
2816 (normalize): New function.
2817 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2818 name table into account when computing the file offsets in the
2819 SOM dictionary. Make sure to align to an even boundary.
2820 (som_write_armap): Initialize the checksum to zero.
2821 (ar_maxchars): Fix. Opps.
2823 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2825 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2826 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2828 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2830 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2831 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2832 * bfd-in2.h: Regenerated.
2834 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2835 this was also named trad_unix_bfd_copy_private_bfd_data.
2837 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2839 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2840 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2841 returns NULL, it is not an error. It's possible that some of
2842 these checks are not necessary (because the size can never be
2843 zero), but putting in the checks is the conservative thing to do
2844 in light of the fact that some of these malloc calls replaced
2845 unchecked alloca calls, in which a zero argument would work fine.
2847 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2849 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2850 duplicate definition.
2851 (osf_core_bfd_is_local_label): Define.
2853 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2854 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2855 failure indication, it merely means there are no relocs.
2857 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2858 after NAME, since SunOS /bin/cc can't handle it.
2860 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2862 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2863 From sukes@glue.umd.edu (Tasuki Hirata).
2865 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2867 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2868 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2869 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2871 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2873 * som.c (som_prep_for_fixups): Detect section symbols based
2874 on either the lack of private data or the symbol flags. Do not
2875 munge section symbol names anymore -- they no longer confuse GDB.
2876 (som_begin_writing): Leave space for an exec header if writing
2878 (som_slurp_symbol_table): Recognize both forms of section symbol
2879 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2880 section symbols to be the name of the section they represent.
2881 Debugging symbols begin with "L$0\001", not just "L$".
2883 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2885 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2887 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2888 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2889 and bfd_is_local_label.
2891 * targets.c: Add new entries to the bfd_target structure.
2893 * bfd.c (bfd_copy_private_bfd_data): New definition.
2895 * section.c (bfd_copy_private_section_data): New definition.
2897 * syms.c (bfd_is_local_label): New definition.
2899 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2901 * libbfd.c (bfd_generic_is_local_label): New function.
2903 * *-core.c: Provide default definitions for new functions in
2904 the target vector which all point to bfd_false.
2906 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2907 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2908 Default new vectors for copying private backend data to bfd_true.
2909 Default new vector for determining if a symbol is a local label
2910 to bfd_generic_is_local_label.
2912 * som.c (som_bfd_copy_private_section_data): New function.
2913 (som_bfd_is_local_label): New function.
2914 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2916 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2918 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2920 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2922 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2925 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2926 Indent some of them to GNU standards.
2928 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2929 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2930 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2931 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2932 Update copyright years.
2934 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2936 * som.c (som_prep_for_fixups): A relocation involving the section
2937 symbol for the *ABS* section is really a relocation involving
2939 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2940 undefined symbols. Correctly distinguish between debugger symbols
2941 and section symbols.
2943 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2944 for spaces and subspaces.
2946 * som.c (som_bfd_count_ar_symbols): Fix typo.
2948 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2949 HAS_RELOC based on the object's magic number.
2950 (make_unique_section): Delete function. BFD and its users are
2951 prepared to handle multiple sections with the same name.
2952 (setup_sections): Allocate space on the BFD's obstack to hold
2953 section names. Use bfd_make_setion_anyway rather than the
2954 obsolete make_unique_section.
2955 (som_prep_headers): Choose the correct SOM magic number based
2957 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2959 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2961 * elf32-ppc.c: Renamed from elf32-powerpc.c.

2971 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2972 is always located at the start of the data section to allow
2973 recovery of the dynamic info from a stripped executable.
2974 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2977 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2979 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2980 cruft (like the #pragma alloca for AIX).
2981 In addition to that problem, the C alloca calls xmalloc, which
2982 means checking for being out of memory can't work right. The
2983 following changes remove all uses of alloca from BFD.
2984 * hosts/solaris2.h: Remove alloca cruft.
2985 * som.c: Replace alloca with a fixed size auto array.

2990 * linker.c: Replace alloca with obstack_alloc.
2991 * libbfd.h: Rebuilt.
2993 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2995 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2998 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3000 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
3001 Elf*_Off typedefs by their expansion, the typedefs have been
3002 removed from include/elf/internal.h.
3003 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
3004 SHT_PROGBITS section.
3006 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3008 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
3010 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3012 * configure.host: Recognize i[34]86-sequent-*.
3014 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
3015 return from bfd_seek indicates an error.
3016 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3017 TRAD_CORE_STACK_OFFSET.
3018 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3019 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3021 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3023 * som.[ch]: Do not include libhppa.h in som.c, instead include
3026 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3027 include it in elf32-hppa.h.
3029 * som.c (log2): Return -1 on error rather than aborting.

3334 bother processing them.
3335 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4038 The sparc (and possibly other?) NLM format requires a different
4039 way to write exports, so add a write_export field to the backend
4040 data (and set it to NULL for everything but the sparc).
