2586 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2588 * som.c (bfd_section_from_som_symbol): Only to do the value
2589 comparison for function symbols within executables.
2591 * som.c (bfd_section_from_som_symbol): Renamed from
2592 som_section_from_subspace_index. Pass in a native SOM symbol.
2593 For executables, iterate through the sections to find out
2594 which contains the symbol's address rather than using the
2595 symbol_info field. (symbol_info has a different meaning for
2596 dynamicly linked executables.)
2598 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2601 * som.c (som_begin_writing): Fix braino (one call to align
2602 space/subspace data was done unconditionally rather than
2603 just for executables.)
2605 * som.c (som_begin_writing): Align text in all executables to
2606 make HPUX kernel happy. Fixes strip/objcopy for shared
2609 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2611 * som.c (som_begin_writing): Account for alignment needs of
2612 subspaces too when writing executables. Never request a negative
2613 bss size. Fixes some problems with demand paged executables,
2614 still having problems with pure executables and shared executables.
2616 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2618 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2619 bfd_zalloc for rawptr, because later on we may call free, not
2622 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2623 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2624 * cisco-core.c: New file.
2625 * Makefile.in: Change accordingly.
2626 * configure.in: Recognize cisco_core_vec.
2627 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2628 * targets.c: Add cisco_core_vec.
2629 * bfd-in2.h: Rebuilt.
2631 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2633 * som.h (som_copyable_section_data_struct): New structure
2634 containing all the private section information which needs
2635 to be copied from input section to output section during
2637 (som_section_data_struct): Remove several fields now in
2638 som_copyable_section_data_struct. Make the space and
2639 subspace dictionaries be pointers (to save space when
2640 only reading objects).
2642 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2643 some references changed. Allocate a copyable data stucture if
2644 none exists. Store info into the copyable data structure.
2645 (bfd_som_set_subsection_attributes): Likewise.
2646 (som_is_space, som_is_subspace, som_is_container): New functions.
2647 Use these instead of directly accessing private data.
2648 (som_prep_headers): Allocate space and subspace headers here.
2649 Fill in some fields in the space/subspace headers from the
2651 (som_bfd_copy_private_section_data): Only copy the stuff
2652 that we really need to make objcopy and strip work. Allocate
2653 the copy_data structure for the output bfd before copying.
2655 * som.h (struct som_exec_data): New structure to hold exec
2656 info that must be preserved when running objcopy/strip.
2657 (struct somdata): Add new "exec_data" field and accessor
2658 macro. Add some comments on how the various fields are used.
2659 (som_section_data_struct): Make is_space and is_subspace bitfields.
2660 Delete unused subspace_index. All references now use the
2661 target_index field within the section structure itself.
2663 * som.c (make_unique_section): Delete unused declaration.
2664 (som_bfd_copy_private_bfd_data): New function.
2665 (som_object_setup): Allocate space for and save exec information
2666 that needs to be copied during objcopy/strip.
2667 (som_mkobject): Do not allocate space for a file header here.
2668 It is not used when only reading SOM objects.
2669 (som_prep_headers): Allocate space for and attach a file header
2670 to the output bfd. For executables, use the saved system_id
2671 value rather than trying to guess the right value. Do not abort
2672 wwhen setting file_hdr->entry* for executables.
2673 (som_begin_writing): For executables, set the exec_entry and
2675 (som_copy_private_backend_section_data): Always return a value.
2677 * libhppa.h (PA_PAGESIZE): Define.
2679 * som.c (SOM_ALIGN): Define.
2680 (som_begin_writing): If writing an executable, initialize all
2681 fields in the exec header to zero. Update fields in the exec
2682 header as sizes of loadable subspaces are computed. Carefully
2683 preserve alignments when building executables. Actually write the
2684 exec after all the fields are filled in.
2686 * Better long-filename handling. Reads SOM ABI compliant extended
2687 names, but doesn't quite write compliant extended names yet.
2688 * som.c (som_slurp_extended_name_table): Delete function. The
2689 generic code will handle things correctly.
2690 (som_slurp_armap): Seek to the beginning of the next member.
2691 (normalize): New function.
2692 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2693 name table into account when computing the file offsets in the
2694 SOM dictionary. Make sure to align to an even boundary.
2695 (som_write_armap): Initialize the checksum to zero.
2696 (ar_maxchars): Fix. Opps.
2698 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2700 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2701 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2703 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2705 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2706 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2707 * bfd-in2.h: Regenerated.
2709 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2710 this was also named trad_unix_bfd_copy_private_bfd_data.
2712 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2714 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2715 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2716 returns NULL, it is not an error. It's possible that some of
2717 these checks are not necessary (because the size can never be
2718 zero), but putting in the checks is the conservative thing to do
2719 in light of the fact that some of these malloc calls replaced
2720 unchecked alloca calls, in which a zero argument would work fine.
2722 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2724 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2725 duplicate definition.
2726 (osf_core_bfd_is_local_label): Define.
2728 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2729 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2730 failure indication, it merely means there are no relocs.
2732 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2733 after NAME, since SunOS /bin/cc can't handle it.
2735 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2737 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2738 From sukes@glue.umd.edu (Tasuki Hirata).
2740 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2742 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2743 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2744 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2746 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2748 * som.c (som_prep_for_fixups): Detect section symbols based
2749 on either the lack of private data or the symbol flags. Do not
2750 munge section symbol names anymore -- they no longer confuse GDB.
2751 (som_begin_writing): Leave space for an exec header if writing
2753 (som_slurp_symbol_table): Recognize both forms of section symbol
2754 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2755 section symbols to be the name of the section they represent.
2756 Debugging symbols begin with "L$0\001", not just "L$".
2758 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2760 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2762 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2763 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2764 and bfd_is_local_label.
2766 * targets.c: Add new entries to the bfd_target structure.
2768 * bfd.c (bfd_copy_private_bfd_data): New definition.
2770 * section.c (bfd_copy_private_section_data): New definition.
2772 * syms.c (bfd_is_local_label): New definition.
2774 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2776 * libbfd.c (bfd_generic_is_local_label): New function.
2778 * *-core.c: Provide default definitions for new functions in
2779 the target vector which all point to bfd_false.
2781 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2782 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2783 Default new vectors for copying private backend data to bfd_true.
2784 Default new vector for determining if a symbol is a local label
2785 to bfd_generic_is_local_label.
2787 * som.c (som_bfd_copy_private_section_data): New function.
2788 (som_bfd_is_local_label): New function.
2789 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2791 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2793 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2795 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2797 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2800 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2801 Indent some of them to GNU standards.
2803 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2804 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2805 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2806 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2807 Update copyright years.
2809 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2811 * som.c (som_prep_for_fixups): A relocation involving the section
2812 symbol for the *ABS* section is really a relocation involving
2814 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2815 undefined symbols. Correctly distinguish between debugger symbols
2816 and section symbols.
2818 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2819 for spaces and subspaces.
2821 * som.c (som_bfd_count_ar_symbols): Fix typo.
2823 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2824 HAS_RELOC based on the object's magic number.
2825 (make_unique_section): Delete function. BFD and its users are
2826 prepared to handle multiple sections with the same name.
2827 (setup_sections): Allocate space on the BFD's obstack to hold
2828 section names. Use bfd_make_setion_anyway rather than the
2829 obsolete make_unique_section.
2830 (som_prep_headers): Choose the correct SOM magic number based
2832 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2834 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2836 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2837 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2838 * Makefile.in, configure.in: Corresponding changes.
2840 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2842 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
2844 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2846 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2847 is always located at the start of the data section to allow
2848 recovery of the dynamic info from a stripped executable.
2849 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2852 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2854 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2855 cruft (like the #pragma alloca for AIX).
2856 In addition to that problem, the C alloca calls xmalloc, which
2857 means checking for being out of memory can't work right. The
2858 following changes remove all uses of alloca from BFD.
2859 * hosts/solaris2.h: Remove alloca cruft.
2860 * som.c: Replace alloca with a fixed size auto array.
2861 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
2862 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
2863 sunos.c: Replace alloca with malloc and appropriate error checking and
2865 * linker.c: Replace alloca with obstack_alloc.
2866 * libbfd.h: Rebuilt.
2868 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2870 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2873 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2875 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2876 Elf*_Off typedefs by their expansion, the typedefs have been
2877 removed from include/elf/internal.h.
2878 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2879 SHT_PROGBITS section.
2881 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2883 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2887 * configure.host: Recognize i[34]86-sequent-*.
2889 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2890 return from bfd_seek indicates an error.
2891 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2892 TRAD_CORE_STACK_OFFSET.
2893 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2894 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2896 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2898 * som.[ch]: Do not include libhppa.h in som.c, instead include
2901 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2902 include it in elf32-hppa.h.
2904 * som.c (log2): Return -1 on error rather than aborting.
2905 (setup_sections): Bubble up an error from log2.
2907 * Changes to make HP C compiler happy in both traditional
2909 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2911 (bfd_som_set_section_attributes): Use unsigned int rather than
2912 unsigned char to avoid GNU-C extensions.
2913 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2914 or failure rather than aborting on failure.
2916 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2918 (bfd_som_attach_aux_hdr): Add prototype.
2919 (hppa_som-gen_reloc_type): Likewise.
2921 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2922 (hppa_look_for_stubs_in_section): Do not return false on failure
2923 until rest of code is ready to handle it. Abort for now.
2925 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2927 * bfd-in2.h: Rebuilt.
2929 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
2931 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.

2935 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
2937 * config.bfd : Add i386-os9k.
2938 * config/i386-os9k.mt : Newly add os9k target makefile.
2940 * i386os9k.c : new file to handle os9k format bfd.
2941 * Makefile.in : Handle new file i386os9k.c
2942 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
2943 * cache.c : Initialize cache_sentinel to 0.

2947 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
2948 action in case where caller specified no argument relocation.
2949 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2950 right in the original relocation and the stub's relocation.
2952 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
2953 unused symbols argument.
2955 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
2956 than asymbol * for original target symbol. All callers changed.
2957 Set reloc->sym_ptr_ptr appropriately.
2958 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2959 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2960 argument. Use the output symbols when canonicalizing the relocs,
2961 creating them if necessary.
2963 * linker.c (_bfd_generic_link_output_symbols): Do not
2964 rebuild/clobber the output symbols if they already exist.
2966 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
2968 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
2969 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
2970 * bfd-in2.h: Rebuilt.
2972 * srec.c (hex_value): Always set to a size of 256 bytes.
2973 (srec_init): Cosmetic changes.
2975 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2977 * elf32-hppa.c: Second half of major cleanup. More comments,
2978 PARAMize and staticize rest of functions. Delete unused
2979 functions. Delete unused/unnecessary arguments to some functions.
2980 Group static vars together. Abort for bad errors until we have
2981 error code propogation working. Work on spacing and indention.
2982 Add FIXMEs for unresolved problems. Use enums rather than
2983 #defines for lots of things. Merge two functions which build
2984 linker stubs into a single function (so they can easily share a
2985 ton of common code).
2987 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2989 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2990 avoid depending upon right shifts of signed numbers, and to
2991 correct handling of src_mask with lower bits zero.
2993 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
2994 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

3001 (write_shdrs_and_ehdr): Make count unsigned.
3002 (assign_file_positions_for_relocs): Make i unsigned.
3003 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
3004 (section_from_elf_index): Make index argument unsigned.
3006 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
3008 * elfcode.h: Don't include assert.h.
3009 (swap_out_syms): Use BFD_ASSERT rather than assert.

3014 * hosts/i386v4.h (qsort, strtol): Remove incorrect and useless
3017 Fri Feb 25 16:35:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3019 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
3021 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
3022 (elf_hppa_tc_make_sections): Likewise.
3023 (elf_hppa_final_processing): Add extern decl.
3025 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
3026 comments. PARAMize some static functions. Delete unused functions.
3027 Delete unused/unnecessary arguments to many functions. Group
3028 static vars together. Collapse common case statements together
3029 in many places. Use default case when possible instead of listing
3030 each case separately. Abort for bad errors until we get error
3031 code propogation working. Work on spacing and indention problems.
3032 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3033 COMPLEX relocation support (it's never used anyway).
3034 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3035 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3036 (elf_hppa_tc_make_sections): Likewise.
3038 * format.c (bfd_check_format_matches): Initialize matching_vector
3039 to keep gcc -Wall quiet.

3775 bfd_som_set_subsection_attributes): Change parameters from char
3776 to int. Following a prototype with an old-style function definition

3879 the symbol value and check for undefined symbols.
3880 (get_value): If the symbol is undefined, look it up in the linker
3882 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
3883 use get_value to get the symbol value and check for undefined
3885 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
3886 undefined, look it up in the linker hash table.
3888 * aoutx.h (translate_symbol_table): The string index 0 has a

3913 The sparc (and possibly other?) NLM format requires a different
3914 way to write exports, so add a write_export field to the backend
3915 data (and set it to NULL for everything but the sparc).
