2596 (_bfd_generic_final_link): Likewise.
2597 (_bfd_generic_link_output_symbols): Likewise.

2600 in asymbol udata field.
2602 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2604 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
2605 reloc, used in embedded PIC code.
2606 (mips_adjust_reloc_in): Change sanity check to permit new reloc.

2613 link_order loop. Use _bfd_generic_link_add_symbols_collect for
2614 add_symbls entry point.
2616 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
2617 counting relocs. Set SEC_RELOC flag for any section which has

2622 * linker.c (_bfd_generic_link_add_symbols): Just call
2623 generic_link_add_symbols.
2624 (_bfd_generic_link_add_symbols_collect): New function, like
2625 _bfd_generic_link_add_symbols but also collect constructors and
2626 destructors by name as collect2 does.
2627 (generic_link_add_symbols): New function, like old
2628 _bfd_generic_link_add_symbols but with collect argument.
2629 (generic_link_add_object_symbols): Take collect argument.

2641 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
2642 for first character in an extended name.
2643 (_bfd_write_archive_contents): If ar_padchar == '/', then use
2644 "//" as the name of the special archive member holding the
2645 extended name table.
2647 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2649 Support for link_order types which generate relocs in order to
2650 support -Ur in the linker.
2651 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2652 from call to _bfd_generic_link_add_one_symbol.
2653 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2654 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2655 instead of bitsize to add_to_set call back.
2656 (_bfd_generic_final_link): Account for link_order relocs when
2657 allocating space for relocations. Handle them in link_order loop.
2658 (_bfd_generic_reloc_link_order): New function.
2659 (_bfd_default_link_order): If a reloc_link_order is seen here,
2661 (_bfd_count_link_order_relocs): New function.
2662 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
2663 argument from declaration.
2664 (_bfd_generic_reloc_link_order): Declare.
2665 (_bfd_count_link_order_relocs): Declare.
2666 * libbfd.h: Rebuilt.
2667 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
2668 call to _bfd_generic_link_add_one_symbol.
2669 (NAME(aout,final_link)): Account for link_order relocs when

2674 call to _bfd_generic_link_add_one_symbol.
2675 (ecoff_bfd_final_link): Account for link_order relocs when
2676 allocating space for relocations. Handle them in link_order loop.
2677 (ecoff_link_write_external): Set the storage class of a defined
2678 linker created symbol based on the section it is in. Correct
2679 bfd_link_hash_weak case to use .sc rather than .st.
2680 (ecoff_reloc_link_order): New function.
2681 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2683 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

2688 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2689 bfd_zmalloc. Free a pointer, not a union.
2690 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2692 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2694 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2696 * som.c (bfd_section_from_som_symbol): Only to do the value
2697 comparison for function symbols within executables.
2699 * som.c (bfd_section_from_som_symbol): Renamed from
2700 som_section_from_subspace_index. Pass in a native SOM symbol.
2701 For executables, iterate through the sections to find out
2702 which contains the symbol's address rather than using the
2703 symbol_info field. (symbol_info has a different meaning for
2704 dynamicly linked executables.)
2706 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2709 * som.c (som_begin_writing): Fix braino (one call to align
2710 space/subspace data was done unconditionally rather than
2711 just for executables.)
2713 * som.c (som_begin_writing): Align text in all executables to
2714 make HPUX kernel happy. Fixes strip/objcopy for shared
2717 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2719 * som.c (som_begin_writing): Account for alignment needs of
2720 subspaces too when writing executables. Never request a negative
2721 bss size. Fixes some problems with demand paged executables,
2722 still having problems with pure executables and shared executables.
2724 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2726 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2727 bfd_zalloc for rawptr, because later on we may call free, not
2730 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2731 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2732 * cisco-core.c: New file.
2733 * Makefile.in: Change accordingly.
2734 * configure.in: Recognize cisco_core_vec.
2735 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2736 * targets.c: Add cisco_core_vec.
2737 * bfd-in2.h: Rebuilt.
2739 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2741 * som.h (som_copyable_section_data_struct): New structure
2742 containing all the private section information which needs
2743 to be copied from input section to output section during
2745 (som_section_data_struct): Remove several fields now in
2746 som_copyable_section_data_struct. Make the space and
2747 subspace dictionaries be pointers (to save space when
2748 only reading objects).
2750 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2751 some references changed. Allocate a copyable data stucture if
2752 none exists. Store info into the copyable data structure.
2753 (bfd_som_set_subsection_attributes): Likewise.
2754 (som_is_space, som_is_subspace, som_is_container): New functions.
2755 Use these instead of directly accessing private data.
2756 (som_prep_headers): Allocate space and subspace headers here.
2757 Fill in some fields in the space/subspace headers from the
2759 (som_bfd_copy_private_section_data): Only copy the stuff
2760 that we really need to make objcopy and strip work. Allocate
2761 the copy_data structure for the output bfd before copying.
2763 * som.h (struct som_exec_data): New structure to hold exec
2764 info that must be preserved when running objcopy/strip.
2765 (struct somdata): Add new "exec_data" field and accessor
2766 macro. Add some comments on how the various fields are used.
2767 (som_section_data_struct): Make is_space and is_subspace bitfields.
2768 Delete unused subspace_index. All references now use the
2769 target_index field within the section structure itself.
2771 * som.c (make_unique_section): Delete unused declaration.
2772 (som_bfd_copy_private_bfd_data): New function.
2773 (som_object_setup): Allocate space for and save exec information
2774 that needs to be copied during objcopy/strip.
2775 (som_mkobject): Do not allocate space for a file header here.
2776 It is not used when only reading SOM objects.
2777 (som_prep_headers): Allocate space for and attach a file header
2778 to the output bfd. For executables, use the saved system_id
2779 value rather than trying to guess the right value. Do not abort
2780 wwhen setting file_hdr->entry* for executables.
2781 (som_begin_writing): For executables, set the exec_entry and
2783 (som_copy_private_backend_section_data): Always return a value.
2785 * libhppa.h (PA_PAGESIZE): Define.
2787 * som.c (SOM_ALIGN): Define.
2788 (som_begin_writing): If writing an executable, initialize all
2789 fields in the exec header to zero. Update fields in the exec
2790 header as sizes of loadable subspaces are computed. Carefully
2791 preserve alignments when building executables. Actually write the
2792 exec after all the fields are filled in.
2794 * Better long-filename handling. Reads SOM ABI compliant extended
2795 names, but doesn't quite write compliant extended names yet.
2796 * som.c (som_slurp_extended_name_table): Delete function. The
2797 generic code will handle things correctly.
2798 (som_slurp_armap): Seek to the beginning of the next member.
2799 (normalize): New function.
2800 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2801 name table into account when computing the file offsets in the
2802 SOM dictionary. Make sure to align to an even boundary.
2803 (som_write_armap): Initialize the checksum to zero.
2804 (ar_maxchars): Fix. Opps.
2806 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2808 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2809 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2811 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2813 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2814 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2815 * bfd-in2.h: Regenerated.
2817 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2818 this was also named trad_unix_bfd_copy_private_bfd_data.
2820 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2822 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2823 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2824 returns NULL, it is not an error. It's possible that some of
2825 these checks are not necessary (because the size can never be
2826 zero), but putting in the checks is the conservative thing to do
2827 in light of the fact that some of these malloc calls replaced
2828 unchecked alloca calls, in which a zero argument would work fine.
2830 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2832 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2833 duplicate definition.
2834 (osf_core_bfd_is_local_label): Define.
2836 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2837 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2838 failure indication, it merely means there are no relocs.
2840 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2841 after NAME, since SunOS /bin/cc can't handle it.
2843 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2845 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2846 From sukes@glue.umd.edu (Tasuki Hirata).
2848 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2850 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2851 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2852 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2854 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2856 * som.c (som_prep_for_fixups): Detect section symbols based
2857 on either the lack of private data or the symbol flags. Do not
2858 munge section symbol names anymore -- they no longer confuse GDB.
2859 (som_begin_writing): Leave space for an exec header if writing
2861 (som_slurp_symbol_table): Recognize both forms of section symbol
2862 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2863 section symbols to be the name of the section they represent.
2864 Debugging symbols begin with "L$0\001", not just "L$".
2866 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2868 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2870 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2871 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2872 and bfd_is_local_label.
2874 * targets.c: Add new entries to the bfd_target structure.
2876 * bfd.c (bfd_copy_private_bfd_data): New definition.
2878 * section.c (bfd_copy_private_section_data): New definition.
2880 * syms.c (bfd_is_local_label): New definition.
2882 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2884 * libbfd.c (bfd_generic_is_local_label): New function.
2886 * *-core.c: Provide default definitions for new functions in
2887 the target vector which all point to bfd_false.
2889 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2890 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2891 Default new vectors for copying private backend data to bfd_true.
2892 Default new vector for determining if a symbol is a local label
2893 to bfd_generic_is_local_label.
2895 * som.c (som_bfd_copy_private_section_data): New function.
2896 (som_bfd_is_local_label): New function.
2897 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2899 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2901 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2903 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2905 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2908 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2909 Indent some of them to GNU standards.
2911 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2912 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2913 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2914 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2915 Update copyright years.
2917 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2919 * som.c (som_prep_for_fixups): A relocation involving the section
2920 symbol for the *ABS* section is really a relocation involving
2922 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2923 undefined symbols. Correctly distinguish between debugger symbols
2924 and section symbols.
2926 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2927 for spaces and subspaces.
2929 * som.c (som_bfd_count_ar_symbols): Fix typo.
2931 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2932 HAS_RELOC based on the object's magic number.
2933 (make_unique_section): Delete function. BFD and its users are
2934 prepared to handle multiple sections with the same name.
2935 (setup_sections): Allocate space on the BFD's obstack to hold
2936 section names. Use bfd_make_setion_anyway rather than the
2937 obsolete make_unique_section.
2938 (som_prep_headers): Choose the correct SOM magic number based
2940 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2942 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2944 * elf32-ppc.c: Renamed from elf32-powerpc.c.

2954 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2955 is always located at the start of the data section to allow
2956 recovery of the dynamic info from a stripped executable.
2957 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2960 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2962 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2963 cruft (like the #pragma alloca for AIX).
2964 In addition to that problem, the C alloca calls xmalloc, which
2965 means checking for being out of memory can't work right. The
2966 following changes remove all uses of alloca from BFD.
2967 * hosts/solaris2.h: Remove alloca cruft.
2968 * som.c: Replace alloca with a fixed size auto array.

2973 * linker.c: Replace alloca with obstack_alloc.
2974 * libbfd.h: Rebuilt.
2976 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2978 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2981 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2983 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2984 Elf*_Off typedefs by their expansion, the typedefs have been
2985 removed from include/elf/internal.h.
2986 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2987 SHT_PROGBITS section.
2989 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2991 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2995 * configure.host: Recognize i[34]86-sequent-*.
2997 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2998 return from bfd_seek indicates an error.
2999 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
3000 TRAD_CORE_STACK_OFFSET.
3001 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
3002 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
3004 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3006 * som.[ch]: Do not include libhppa.h in som.c, instead include
3009 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
3010 include it in elf32-hppa.h.
3012 * som.c (log2): Return -1 on error rather than aborting.
3013 (setup_sections): Bubble up an error from log2.
3015 * Changes to make HP C compiler happy in both traditional
3017 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
3019 (bfd_som_set_section_attributes): Use unsigned int rather than
3020 unsigned char to avoid GNU-C extensions.
3021 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
3022 or failure rather than aborting on failure.
3024 * som.h (bfd_som_set_section_attributes): Fix prototype to match
3026 (bfd_som_attach_aux_hdr): Add prototype.
3027 (hppa_som-gen_reloc_type): Likewise.
3029 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
3030 (hppa_look_for_stubs_in_section): Do not return false on failure
3031 until rest of code is ready to handle it. Abort for now.

3141 COMPLEX relocation support (it's never used anyway).
3142 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3143 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3144 (elf_hppa_tc_make_sections): Likewise.

3316 (b_out_relax_section): If a section contains no relocations, don't
3317 bother processing them.
3318 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4021 The sparc (and possibly other?) NLM format requires a different
4022 way to write exports, so add a write_export field to the backend
4023 data (and set it to NULL for everything but the sparc).
