2583 bfd_link_hash_weak case to use .sc rather than .st.
2584 (ecoff_reloc_link_order): New function.
2585 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2587 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
2589 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
2592 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2593 bfd_zmalloc. Free a pointer, not a union.
2594 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2596 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2598 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2600 * som.c (bfd_section_from_som_symbol): Only to do the value
2601 comparison for function symbols within executables.
2603 * som.c (bfd_section_from_som_symbol): Renamed from
2604 som_section_from_subspace_index. Pass in a native SOM symbol.
2605 For executables, iterate through the sections to find out
2606 which contains the symbol's address rather than using the
2607 symbol_info field. (symbol_info has a different meaning for
2608 dynamicly linked executables.)
2610 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2613 * som.c (som_begin_writing): Fix braino (one call to align
2614 space/subspace data was done unconditionally rather than
2615 just for executables.)
2617 * som.c (som_begin_writing): Align text in all executables to
2618 make HPUX kernel happy. Fixes strip/objcopy for shared
2621 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2623 * som.c (som_begin_writing): Account for alignment needs of
2624 subspaces too when writing executables. Never request a negative
2625 bss size. Fixes some problems with demand paged executables,
2626 still having problems with pure executables and shared executables.
2628 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2630 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2631 bfd_zalloc for rawptr, because later on we may call free, not
2634 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2635 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2636 * cisco-core.c: New file.
2637 * Makefile.in: Change accordingly.
2638 * configure.in: Recognize cisco_core_vec.
2639 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2640 * targets.c: Add cisco_core_vec.
2641 * bfd-in2.h: Rebuilt.
2643 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2645 * som.h (som_copyable_section_data_struct): New structure
2646 containing all the private section information which needs
2647 to be copied from input section to output section during
2649 (som_section_data_struct): Remove several fields now in
2650 som_copyable_section_data_struct. Make the space and
2651 subspace dictionaries be pointers (to save space when
2652 only reading objects).
2654 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2655 some references changed. Allocate a copyable data stucture if
2656 none exists. Store info into the copyable data structure.
2657 (bfd_som_set_subsection_attributes): Likewise.
2658 (som_is_space, som_is_subspace, som_is_container): New functions.
2659 Use these instead of directly accessing private data.
2660 (som_prep_headers): Allocate space and subspace headers here.
2661 Fill in some fields in the space/subspace headers from the
2663 (som_bfd_copy_private_section_data): Only copy the stuff
2664 that we really need to make objcopy and strip work. Allocate
2665 the copy_data structure for the output bfd before copying.
2667 * som.h (struct som_exec_data): New structure to hold exec
2668 info that must be preserved when running objcopy/strip.
2669 (struct somdata): Add new "exec_data" field and accessor
2670 macro. Add some comments on how the various fields are used.
2671 (som_section_data_struct): Make is_space and is_subspace bitfields.
2672 Delete unused subspace_index. All references now use the
2673 target_index field within the section structure itself.
2675 * som.c (make_unique_section): Delete unused declaration.
2676 (som_bfd_copy_private_bfd_data): New function.
2677 (som_object_setup): Allocate space for and save exec information
2678 that needs to be copied during objcopy/strip.
2679 (som_mkobject): Do not allocate space for a file header here.
2680 It is not used when only reading SOM objects.
2681 (som_prep_headers): Allocate space for and attach a file header
2682 to the output bfd. For executables, use the saved system_id
2683 value rather than trying to guess the right value. Do not abort
2684 wwhen setting file_hdr->entry* for executables.
2685 (som_begin_writing): For executables, set the exec_entry and
2687 (som_copy_private_backend_section_data): Always return a value.
2689 * libhppa.h (PA_PAGESIZE): Define.
2691 * som.c (SOM_ALIGN): Define.
2692 (som_begin_writing): If writing an executable, initialize all
2693 fields in the exec header to zero. Update fields in the exec
2694 header as sizes of loadable subspaces are computed. Carefully
2695 preserve alignments when building executables. Actually write the
2696 exec after all the fields are filled in.
2698 * Better long-filename handling. Reads SOM ABI compliant extended
2699 names, but doesn't quite write compliant extended names yet.
2700 * som.c (som_slurp_extended_name_table): Delete function. The
2701 generic code will handle things correctly.
2702 (som_slurp_armap): Seek to the beginning of the next member.
2703 (normalize): New function.
2704 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2705 name table into account when computing the file offsets in the
2706 SOM dictionary. Make sure to align to an even boundary.
2707 (som_write_armap): Initialize the checksum to zero.
2708 (ar_maxchars): Fix. Opps.
2710 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2712 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2713 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2715 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2717 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2718 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2719 * bfd-in2.h: Regenerated.
2721 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2722 this was also named trad_unix_bfd_copy_private_bfd_data.
2724 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2726 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2727 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2728 returns NULL, it is not an error. It's possible that some of
2729 these checks are not necessary (because the size can never be
2730 zero), but putting in the checks is the conservative thing to do
2731 in light of the fact that some of these malloc calls replaced
2732 unchecked alloca calls, in which a zero argument would work fine.
2734 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2736 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2737 duplicate definition.
2738 (osf_core_bfd_is_local_label): Define.
2740 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2741 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2742 failure indication, it merely means there are no relocs.
2744 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2745 after NAME, since SunOS /bin/cc can't handle it.
2747 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2749 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2750 From sukes@glue.umd.edu (Tasuki Hirata).
2752 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2754 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2755 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2756 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2758 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2760 * som.c (som_prep_for_fixups): Detect section symbols based
2761 on either the lack of private data or the symbol flags. Do not
2762 munge section symbol names anymore -- they no longer confuse GDB.
2763 (som_begin_writing): Leave space for an exec header if writing
2765 (som_slurp_symbol_table): Recognize both forms of section symbol
2766 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2767 section symbols to be the name of the section they represent.
2768 Debugging symbols begin with "L$0\001", not just "L$".
2770 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2772 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2774 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2775 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2776 and bfd_is_local_label.
2778 * targets.c: Add new entries to the bfd_target structure.
2780 * bfd.c (bfd_copy_private_bfd_data): New definition.
2782 * section.c (bfd_copy_private_section_data): New definition.
2784 * syms.c (bfd_is_local_label): New definition.
2786 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2788 * libbfd.c (bfd_generic_is_local_label): New function.
2790 * *-core.c: Provide default definitions for new functions in
2791 the target vector which all point to bfd_false.
2793 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2794 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2795 Default new vectors for copying private backend data to bfd_true.
2796 Default new vector for determining if a symbol is a local label
2797 to bfd_generic_is_local_label.
2799 * som.c (som_bfd_copy_private_section_data): New function.
2800 (som_bfd_is_local_label): New function.
2801 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2803 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2805 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2807 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2809 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2812 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2813 Indent some of them to GNU standards.
2815 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2816 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2817 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2818 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2819 Update copyright years.
2821 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2823 * som.c (som_prep_for_fixups): A relocation involving the section
2824 symbol for the *ABS* section is really a relocation involving
2826 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2827 undefined symbols. Correctly distinguish between debugger symbols
2828 and section symbols.
2830 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2831 for spaces and subspaces.
2833 * som.c (som_bfd_count_ar_symbols): Fix typo.
2835 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2836 HAS_RELOC based on the object's magic number.
2837 (make_unique_section): Delete function. BFD and its users are
2838 prepared to handle multiple sections with the same name.
2839 (setup_sections): Allocate space on the BFD's obstack to hold
2840 section names. Use bfd_make_setion_anyway rather than the
2841 obsolete make_unique_section.
2842 (som_prep_headers): Choose the correct SOM magic number based
2844 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2846 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2848 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2849 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2850 * Makefile.in, configure.in: Corresponding changes.
2852 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2854 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
2856 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2858 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2859 is always located at the start of the data section to allow
2860 recovery of the dynamic info from a stripped executable.
2861 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2864 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2866 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2867 cruft (like the #pragma alloca for AIX).
2868 In addition to that problem, the C alloca calls xmalloc, which
2869 means checking for being out of memory can't work right. The
2870 following changes remove all uses of alloca from BFD.
2871 * hosts/solaris2.h: Remove alloca cruft.
2872 * som.c: Replace alloca with a fixed size auto array.
2873 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
2874 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
2875 sunos.c: Replace alloca with malloc and appropriate error checking and
2877 * linker.c: Replace alloca with obstack_alloc.
2878 * libbfd.h: Rebuilt.
2880 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2882 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2885 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2887 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2888 Elf*_Off typedefs by their expansion, the typedefs have been
2889 removed from include/elf/internal.h.
2890 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2891 SHT_PROGBITS section.
2893 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2895 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2901 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2902 return from bfd_seek indicates an error.
2903 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2904 TRAD_CORE_STACK_OFFSET.
2905 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2906 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2908 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2910 * som.[ch]: Do not include libhppa.h in som.c, instead include
2913 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2914 include it in elf32-hppa.h.
2916 * som.c (log2): Return -1 on error rather than aborting.
2917 (setup_sections): Bubble up an error from log2.
2919 * Changes to make HP C compiler happy in both traditional
2921 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2923 (bfd_som_set_section_attributes): Use unsigned int rather than
2924 unsigned char to avoid GNU-C extensions.
2925 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2926 or failure rather than aborting on failure.
2928 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2930 (bfd_som_attach_aux_hdr): Add prototype.
2931 (hppa_som-gen_reloc_type): Likewise.
2933 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2934 (hppa_look_for_stubs_in_section): Do not return false on failure
2935 until rest of code is ready to handle it. Abort for now.

2939 * bfd-in2.h: Rebuilt.
2941 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

2950 * config/i386-os9k.mt : Newly add os9k target makefile.
2952 * i386os9k.c : new file to handle os9k format bfd.
2953 * Makefile.in : Handle new file i386os9k.c
2954 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
2955 * cache.c : Initialize cache_sentinel to 0.

2959 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
2960 action in case where caller specified no argument relocation.
2961 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2962 right in the original relocation and the stub's relocation.
2964 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
2965 unused symbols argument.
2967 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
2968 than asymbol * for original target symbol. All callers changed.
2969 Set reloc->sym_ptr_ptr appropriately.
2970 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2971 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2972 argument. Use the output symbols when canonicalizing the relocs,
2973 creating them if necessary.
2975 * linker.c (_bfd_generic_link_output_symbols): Do not
2976 rebuild/clobber the output symbols if they already exist.
2978 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
2980 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
2981 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
2982 * bfd-in2.h: Rebuilt.
2984 * srec.c (hex_value): Always set to a size of 256 bytes.
2985 (srec_init): Cosmetic changes.
2987 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2989 * elf32-hppa.c: Second half of major cleanup. More comments,
2990 PARAMize and staticize rest of functions. Delete unused
2991 functions. Delete unused/unnecessary arguments to some functions.
2992 Group static vars together. Abort for bad errors until we have
2993 error code propogation working. Work on spacing and indention.
2994 Add FIXMEs for unresolved problems. Use enums rather than
2995 #defines for lots of things. Merge two functions which build
2996 linker stubs into a single function (so they can easily share a
2997 ton of common code).
2999 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3001 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3002 avoid depending upon right shifts of signed numbers, and to
3003 correct handling of src_mask with lower bits zero.
3005 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
3006 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

3026 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
3029 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3031 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
3033 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
3034 (elf_hppa_tc_make_sections): Likewise.
3035 (elf_hppa_final_processing): Add extern decl.
3037 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
3038 comments. PARAMize some static functions. Delete unused functions.
3039 Delete unused/unnecessary arguments to many functions. Group
3040 static vars together. Collapse common case statements together
3041 in many places. Use default case when possible instead of listing

3895 use get_value to get the symbol value and check for undefined
3897 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
3898 undefined, look it up in the linker hash table.
3900 * aoutx.h (translate_symbol_table): The string index 0 has a

3925 The sparc (and possibly other?) NLM format requires a different
3926 way to write exports, so add a write_export field to the backend
