2587 som_copyable_section_data_struct. Make the space and
2588 subspace dictionaries be pointers (to save space when
2589 only reading objects).
2591 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2592 some references changed. Allocate a copyable data stucture if
2593 none exists. Store info into the copyable data structure.
2594 (bfd_som_set_subsection_attributes): Likewise.
2595 (som_is_space, som_is_subspace, som_is_container): New functions.
2596 Use these instead of directly accessing private data.
2597 (som_prep_headers): Allocate space and subspace headers here.
2598 Fill in some fields in the space/subspace headers from the
2600 (som_bfd_copy_private_section_data): Only copy the stuff
2601 that we really need to make objcopy and strip work. Allocate
2602 the copy_data structure for the output bfd before copying.
2604 * som.h (struct som_exec_data): New structure to hold exec
2605 info that must be preserved when running objcopy/strip.
2606 (struct somdata): Add new "exec_data" field and accessor
2607 macro. Add some comments on how the various fields are used.
2608 (som_section_data_struct): Make is_space and is_subspace bitfields.
2609 Delete unused subspace_index. All references now use the
2610 target_index field within the section structure itself.
2612 * som.c (make_unique_section): Delete unused declaration.
2613 (som_bfd_copy_private_bfd_data): New function.
2614 (som_object_setup): Allocate space for and save exec information
2615 that needs to be copied during objcopy/strip.
2616 (som_mkobject): Do not allocate space for a file header here.
2617 It is not used when only reading SOM objects.
2618 (som_prep_headers): Allocate space for and attach a file header
2619 to the output bfd. For executables, use the saved system_id
2620 value rather than trying to guess the right value. Do not abort
2621 wwhen setting file_hdr->entry* for executables.
2622 (som_begin_writing): For executables, set the exec_entry and
2624 (som_copy_private_backend_section_data): Always return a value.
2626 * libhppa.h (PA_PAGESIZE): Define.
2628 * som.c (SOM_ALIGN): Define.
2629 (som_begin_writing): If writing an executable, initialize all
2630 fields in the exec header to zero. Update fields in the exec
2631 header as sizes of loadable subspaces are computed. Carefully
2632 preserve alignments when building executables. Actually write the
2633 exec after all the fields are filled in.
2635 * Better long-filename handling. Reads SOM ABI compliant extended
2636 names, but doesn't quite write compliant extended names yet.
2637 * som.c (som_slurp_extended_name_table): Delete function. The
2638 generic code will handle things correctly.
2639 (som_slurp_armap): Seek to the beginning of the next member.
2640 (normalize): New function.
2641 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2642 name table into account when computing the file offsets in the
2643 SOM dictionary. Make sure to align to an even boundary.
2644 (som_write_armap): Initialize the checksum to zero.
2645 (ar_maxchars): Fix. Opps.
2647 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2649 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2650 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2652 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2654 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2655 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2656 * bfd-in2.h: Regenerated.
2658 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2659 this was also named trad_unix_bfd_copy_private_bfd_data.
2661 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2663 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2664 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2665 returns NULL, it is not an error. It's possible that some of
2666 these checks are not necessary (because the size can never be
2667 zero), but putting in the checks is the conservative thing to do
2668 in light of the fact that some of these malloc calls replaced
2669 unchecked alloca calls, in which a zero argument would work fine.
2671 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2673 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2674 duplicate definition.

2677 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2678 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2679 failure indication, it merely means there are no relocs.
2681 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2682 after NAME, since SunOS /bin/cc can't handle it.
2684 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2686 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2687 From sukes@glue.umd.edu (Tasuki Hirata).
2689 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2691 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2692 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2693 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2695 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2697 * som.c (som_prep_for_fixups): Detect section symbols based
2698 on either the lack of private data or the symbol flags. Do not
2699 munge section symbol names anymore -- they no longer confuse GDB.
2700 (som_begin_writing): Leave space for an exec header if writing
2702 (som_slurp_symbol_table): Recognize both forms of section symbol
2703 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2704 section symbols to be the name of the section they represent.
2705 Debugging symbols begin with "L$0\001", not just "L$".
2707 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2709 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2711 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2712 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2713 and bfd_is_local_label.
2715 * targets.c: Add new entries to the bfd_target structure.
2717 * bfd.c (bfd_copy_private_bfd_data): New definition.

2725 * libbfd.c (bfd_generic_is_local_label): New function.
2727 * *-core.c: Provide default definitions for new functions in
2728 the target vector which all point to bfd_false.
2730 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2731 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2732 Default new vectors for copying private backend data to bfd_true.
2733 Default new vector for determining if a symbol is a local label
2734 to bfd_generic_is_local_label.
2736 * som.c (som_bfd_copy_private_section_data): New function.
2737 (som_bfd_is_local_label): New function.
2738 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2740 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2742 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2744 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2746 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2749 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2750 Indent some of them to GNU standards.
2752 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2753 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2754 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2755 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2756 Update copyright years.
2758 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2760 * som.c (som_prep_for_fixups): A relocation involving the section
2761 symbol for the *ABS* section is really a relocation involving
2763 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2764 undefined symbols. Correctly distinguish between debugger symbols
2765 and section symbols.
2767 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2768 for spaces and subspaces.
2770 * som.c (som_bfd_count_ar_symbols): Fix typo.
2772 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2773 HAS_RELOC based on the object's magic number.
2774 (make_unique_section): Delete function. BFD and its users are
2775 prepared to handle multiple sections with the same name.
2776 (setup_sections): Allocate space on the BFD's obstack to hold
2777 section names. Use bfd_make_setion_anyway rather than the
2778 obsolete make_unique_section.
2779 (som_prep_headers): Choose the correct SOM magic number based
2781 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

2795 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2796 is always located at the start of the data section to allow
2797 recovery of the dynamic info from a stripped executable.
2798 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2801 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2803 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2804 cruft (like the #pragma alloca for AIX).
2805 In addition to that problem, the C alloca calls xmalloc, which
2806 means checking for being out of memory can't work right. The
2807 following changes remove all uses of alloca from BFD.
2808 * hosts/solaris2.h: Remove alloca cruft.
2809 * som.c: Replace alloca with a fixed size auto array.
2810 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

2812 sunos.c: Replace alloca with malloc and appropriate error checking and
2814 * linker.c: Replace alloca with obstack_alloc.
2815 * libbfd.h: Rebuilt.
2817 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2819 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2822 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2824 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2825 Elf*_Off typedefs by their expansion, the typedefs have been
2826 removed from include/elf/internal.h.
2827 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2828 SHT_PROGBITS section.
2830 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2832 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2838 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2839 return from bfd_seek indicates an error.
2840 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2841 TRAD_CORE_STACK_OFFSET.
2842 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2843 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2845 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2847 * som.[ch]: Do not include libhppa.h in som.c, instead include
2850 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2851 include it in elf32-hppa.h.
2853 * som.c (log2): Return -1 on error rather than aborting.
2854 (setup_sections): Bubble up an error from log2.
2856 * Changes to make HP C compiler happy in both traditional
2858 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2860 (bfd_som_set_section_attributes): Use unsigned int rather than
2861 unsigned char to avoid GNU-C extensions.
2862 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2863 or failure rather than aborting on failure.
2865 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2867 (bfd_som_attach_aux_hdr): Add prototype.
2868 (hppa_som-gen_reloc_type): Likewise.
2870 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2871 (hppa_look_for_stubs_in_section): Do not return false on failure
2872 until rest of code is ready to handle it. Abort for now.

2898 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2899 right in the original relocation and the stub's relocation.

2902 unused symbols argument.
2904 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

2906 Set reloc->sym_ptr_ptr appropriately.
2907 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2908 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2909 argument. Use the output symbols when canonicalizing the relocs,
2910 creating them if necessary.
2912 * linker.c (_bfd_generic_link_output_symbols): Do not
2913 rebuild/clobber the output symbols if they already exist.
2915 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
2917 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

2927 PARAMize and staticize rest of functions. Delete unused
2928 functions. Delete unused/unnecessary arguments to some functions.

2930 error code propogation working. Work on spacing and indention.
2931 Add FIXMEs for unresolved problems. Use enums rather than
2932 #defines for lots of things. Merge two functions which build
2933 linker stubs into a single function (so they can easily share a
2934 ton of common code).
2936 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2938 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2939 avoid depending upon right shifts of signed numbers, and to
2940 correct handling of src_mask with lower bits zero.

2970 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
2971 (elf_hppa_tc_make_sections): Likewise.
2972 (elf_hppa_final_processing): Add extern decl.
2974 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
2975 comments. PARAMize some static functions. Delete unused functions.
2976 Delete unused/unnecessary arguments to many functions. Group
2977 static vars together. Collapse common case statements together
2978 in many places. Use default case when possible instead of listing
2979 each case separately. Abort for bad errors until we get error
2980 code propogation working. Work on spacing and indention problems.
2981 Add FIXMEs for some unresolved problems. Delete hopelessly broken
2982 COMPLEX relocation support (it's never used anyway).
2983 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
2984 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
2985 (elf_hppa_tc_make_sections): Likewise.
2987 * format.c (bfd_check_format_matches): Initialize matching_vector
2988 to keep gcc -Wall quiet.

2998 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
3000 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

3026 * elfcode.h (alloca): Delete declaration.
3028 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
3029 number rather than HP9000S800_ID. Note som.c is careful
3030 to make sure CPU_PA_RISC1_0 is always defined.
3032 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
3034 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

3724 bfd_som_set_subsection_attributes): Change parameters from char
3725 to int. Following a prototype with an old-style function definition

3832 use get_value to get the symbol value and check for undefined
3834 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
3835 undefined, look it up in the linker hash table.
3837 * aoutx.h (translate_symbol_table): The string index 0 has a

3862 The sparc (and possibly other?) NLM format requires a different
3863 way to write exports, so add a write_export field to the backend
3864 data (and set it to NULL for everything but the sparc).

3914 read_dynamic_relocs fields.
3915 * aout-target.h (MY(backend_data)): Initialize
