2585 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2587 Support for link_order types which generate relocs in order to
2588 support -Ur in the linker.
2589 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2590 from call to _bfd_generic_link_add_one_symbol.
2591 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2592 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2593 instead of bitsize to add_to_set call back.
2594 (_bfd_generic_final_link): Account for link_order relocs when
2595 allocating space for relocations. Handle them in link_order loop.
2596 (_bfd_generic_reloc_link_order): New function.
2597 (_bfd_default_link_order): If a reloc_link_order is seen here,
2599 (_bfd_count_link_order_relocs): New function.
2600 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
2601 argument from declaration.
2602 (_bfd_generic_reloc_link_order): Declare.
2603 (_bfd_count_link_order_relocs): Declare.
2604 * libbfd.h: Rebuilt.
2605 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
2606 call to _bfd_generic_link_add_one_symbol.
2607 (NAME(aout,final_link)): Account for link_order relocs when
2608 allocating space for relocations. Handle them after handling all
2610 (aout_link_reloc_link_order): New function.
2611 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
2612 call to _bfd_generic_link_add_one_symbol.
2613 (ecoff_bfd_final_link): Account for link_order relocs when
2614 allocating space for relocations. Handle them in link_order loop.
2615 (ecoff_link_write_external): Set the storage class of a defined
2616 linker created symbol based on the section it is in. Correct
2617 bfd_link_hash_weak case to use .sc rather than .st.
2618 (ecoff_reloc_link_order): New function.
2619 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2621 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
2623 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
2626 * cisco-core.c (cisco_core_file_p): Only pass one argument to
2627 bfd_zmalloc. Free a pointer, not a union.
2628 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
2630 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2632 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2634 * som.c (bfd_section_from_som_symbol): Only to do the value
2635 comparison for function symbols within executables.
2637 * som.c (bfd_section_from_som_symbol): Renamed from
2638 som_section_from_subspace_index. Pass in a native SOM symbol.
2639 For executables, iterate through the sections to find out
2640 which contains the symbol's address rather than using the
2641 symbol_info field. (symbol_info has a different meaning for
2642 dynamicly linked executables.)
2644 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2647 * som.c (som_begin_writing): Fix braino (one call to align
2648 space/subspace data was done unconditionally rather than
2649 just for executables.)
2651 * som.c (som_begin_writing): Align text in all executables to
2652 make HPUX kernel happy. Fixes strip/objcopy for shared
2655 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2657 * som.c (som_begin_writing): Account for alignment needs of
2658 subspaces too when writing executables. Never request a negative
2659 bss size. Fixes some problems with demand paged executables,
2660 still having problems with pure executables and shared executables.
2662 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2664 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2665 bfd_zalloc for rawptr, because later on we may call free, not
2668 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2669 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2670 * cisco-core.c: New file.
2671 * Makefile.in: Change accordingly.
2672 * configure.in: Recognize cisco_core_vec.
2673 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2674 * targets.c: Add cisco_core_vec.
2675 * bfd-in2.h: Rebuilt.
2677 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2679 * som.h (som_copyable_section_data_struct): New structure
2680 containing all the private section information which needs
2681 to be copied from input section to output section during
2683 (som_section_data_struct): Remove several fields now in
2684 som_copyable_section_data_struct. Make the space and
2685 subspace dictionaries be pointers (to save space when
2686 only reading objects).
2688 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2689 some references changed. Allocate a copyable data stucture if
2690 none exists. Store info into the copyable data structure.
2691 (bfd_som_set_subsection_attributes): Likewise.
2692 (som_is_space, som_is_subspace, som_is_container): New functions.
2693 Use these instead of directly accessing private data.
2694 (som_prep_headers): Allocate space and subspace headers here.
2695 Fill in some fields in the space/subspace headers from the
2697 (som_bfd_copy_private_section_data): Only copy the stuff
2698 that we really need to make objcopy and strip work. Allocate
2699 the copy_data structure for the output bfd before copying.
2701 * som.h (struct som_exec_data): New structure to hold exec
2702 info that must be preserved when running objcopy/strip.
2703 (struct somdata): Add new "exec_data" field and accessor
2704 macro. Add some comments on how the various fields are used.
2705 (som_section_data_struct): Make is_space and is_subspace bitfields.
2706 Delete unused subspace_index. All references now use the
2707 target_index field within the section structure itself.
2709 * som.c (make_unique_section): Delete unused declaration.
2710 (som_bfd_copy_private_bfd_data): New function.
2711 (som_object_setup): Allocate space for and save exec information
2712 that needs to be copied during objcopy/strip.
2713 (som_mkobject): Do not allocate space for a file header here.
2714 It is not used when only reading SOM objects.
2715 (som_prep_headers): Allocate space for and attach a file header
2716 to the output bfd. For executables, use the saved system_id
2717 value rather than trying to guess the right value. Do not abort
2718 wwhen setting file_hdr->entry* for executables.
2719 (som_begin_writing): For executables, set the exec_entry and
2721 (som_copy_private_backend_section_data): Always return a value.
2723 * libhppa.h (PA_PAGESIZE): Define.
2725 * som.c (SOM_ALIGN): Define.
2726 (som_begin_writing): If writing an executable, initialize all
2727 fields in the exec header to zero. Update fields in the exec
2728 header as sizes of loadable subspaces are computed. Carefully
2729 preserve alignments when building executables. Actually write the
2730 exec after all the fields are filled in.
2732 * Better long-filename handling. Reads SOM ABI compliant extended
2733 names, but doesn't quite write compliant extended names yet.
2734 * som.c (som_slurp_extended_name_table): Delete function. The
2735 generic code will handle things correctly.
2736 (som_slurp_armap): Seek to the beginning of the next member.
2737 (normalize): New function.
2738 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2739 name table into account when computing the file offsets in the
2740 SOM dictionary. Make sure to align to an even boundary.
2741 (som_write_armap): Initialize the checksum to zero.
2742 (ar_maxchars): Fix. Opps.
2744 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2746 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2747 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2749 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2751 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2752 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2753 * bfd-in2.h: Regenerated.
2755 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2756 this was also named trad_unix_bfd_copy_private_bfd_data.
2758 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2760 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2761 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2762 returns NULL, it is not an error. It's possible that some of
2763 these checks are not necessary (because the size can never be
2764 zero), but putting in the checks is the conservative thing to do
2765 in light of the fact that some of these malloc calls replaced
2766 unchecked alloca calls, in which a zero argument would work fine.
2768 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2770 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2771 duplicate definition.
2772 (osf_core_bfd_is_local_label): Define.
2774 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2775 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2776 failure indication, it merely means there are no relocs.
2778 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2779 after NAME, since SunOS /bin/cc can't handle it.
2781 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2783 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2784 From sukes@glue.umd.edu (Tasuki Hirata).
2786 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2788 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2789 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2790 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2792 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2794 * som.c (som_prep_for_fixups): Detect section symbols based
2795 on either the lack of private data or the symbol flags. Do not
2796 munge section symbol names anymore -- they no longer confuse GDB.
2797 (som_begin_writing): Leave space for an exec header if writing
2799 (som_slurp_symbol_table): Recognize both forms of section symbol
2800 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2801 section symbols to be the name of the section they represent.
2802 Debugging symbols begin with "L$0\001", not just "L$".
2804 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2806 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2808 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2809 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2810 and bfd_is_local_label.
2812 * targets.c: Add new entries to the bfd_target structure.
2814 * bfd.c (bfd_copy_private_bfd_data): New definition.
2816 * section.c (bfd_copy_private_section_data): New definition.
2818 * syms.c (bfd_is_local_label): New definition.
2820 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2822 * libbfd.c (bfd_generic_is_local_label): New function.
2824 * *-core.c: Provide default definitions for new functions in
2825 the target vector which all point to bfd_false.
2827 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2828 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2829 Default new vectors for copying private backend data to bfd_true.
2830 Default new vector for determining if a symbol is a local label
2831 to bfd_generic_is_local_label.
2833 * som.c (som_bfd_copy_private_section_data): New function.
2834 (som_bfd_is_local_label): New function.
2835 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2837 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2839 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2841 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2843 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2846 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2847 Indent some of them to GNU standards.
2849 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2850 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2851 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2852 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2853 Update copyright years.
2855 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2857 * som.c (som_prep_for_fixups): A relocation involving the section
2858 symbol for the *ABS* section is really a relocation involving
2860 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2861 undefined symbols. Correctly distinguish between debugger symbols
2862 and section symbols.
2864 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2865 for spaces and subspaces.
2867 * som.c (som_bfd_count_ar_symbols): Fix typo.
2869 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2870 HAS_RELOC based on the object's magic number.
2871 (make_unique_section): Delete function. BFD and its users are
2872 prepared to handle multiple sections with the same name.
2873 (setup_sections): Allocate space on the BFD's obstack to hold
2874 section names. Use bfd_make_setion_anyway rather than the
2875 obsolete make_unique_section.
2876 (som_prep_headers): Choose the correct SOM magic number based
2878 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2880 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2882 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2883 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2884 * Makefile.in, configure.in: Corresponding changes.
2886 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2888 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
2890 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2892 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2893 is always located at the start of the data section to allow
2894 recovery of the dynamic info from a stripped executable.
2895 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2898 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2900 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2901 cruft (like the #pragma alloca for AIX).
2902 In addition to that problem, the C alloca calls xmalloc, which
2903 means checking for being out of memory can't work right. The
2904 following changes remove all uses of alloca from BFD.
2905 * hosts/solaris2.h: Remove alloca cruft.
2906 * som.c: Replace alloca with a fixed size auto array.
2907 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
2908 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
2909 sunos.c: Replace alloca with malloc and appropriate error checking and
2911 * linker.c: Replace alloca with obstack_alloc.
2912 * libbfd.h: Rebuilt.
2914 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2916 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2919 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2921 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2922 Elf*_Off typedefs by their expansion, the typedefs have been
2923 removed from include/elf/internal.h.
2924 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2925 SHT_PROGBITS section.
2927 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2929 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
2931 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2933 * configure.host: Recognize i[34]86-sequent-*.
2935 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2936 return from bfd_seek indicates an error.
2937 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2938 TRAD_CORE_STACK_OFFSET.
2939 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2940 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2942 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2944 * som.[ch]: Do not include libhppa.h in som.c, instead include
2947 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2948 include it in elf32-hppa.h.
2950 * som.c (log2): Return -1 on error rather than aborting.
2951 (setup_sections): Bubble up an error from log2.
2953 * Changes to make HP C compiler happy in both traditional
2955 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2957 (bfd_som_set_section_attributes): Use unsigned int rather than
2958 unsigned char to avoid GNU-C extensions.
2959 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2960 or failure rather than aborting on failure.
2962 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2964 (bfd_som_attach_aux_hdr): Add prototype.
2965 (hppa_som-gen_reloc_type): Likewise.
2967 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2968 (hppa_look_for_stubs_in_section): Do not return false on failure
2969 until rest of code is ready to handle it. Abort for now.
2971 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2973 * bfd-in2.h: Rebuilt.
2975 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
2977 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
2978 * Makefile.in: delete an extra blank.
2979 * configure.in : Add i396os9k_vec.
2981 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
2983 * config.bfd : Add i386-os9k.
2984 * config/i386-os9k.mt : Newly add os9k target makefile.
2986 * i386os9k.c : new file to handle os9k format bfd.
2987 * Makefile.in : Handle new file i386os9k.c
2988 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
2989 * cache.c : Initialize cache_sentinel to 0.
2991 Sun Feb 27 16:30:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2993 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
2994 action in case where caller specified no argument relocation.
2995 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2996 right in the original relocation and the stub's relocation.
2998 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
2999 unused symbols argument.
3001 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
3002 than asymbol * for original target symbol. All callers changed.
3003 Set reloc->sym_ptr_ptr appropriately.
3004 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
3005 (hppa_elf_look_for_stubs_in_section): No longer need symbols
3006 argument. Use the output symbols when canonicalizing the relocs,
3007 creating them if necessary.
3009 * linker.c (_bfd_generic_link_output_symbols): Do not
3010 rebuild/clobber the output symbols if they already exist.
3012 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
3014 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
3015 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
3016 * bfd-in2.h: Rebuilt.
3018 * srec.c (hex_value): Always set to a size of 256 bytes.
3019 (srec_init): Cosmetic changes.
3021 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3023 * elf32-hppa.c: Second half of major cleanup. More comments,
3024 PARAMize and staticize rest of functions. Delete unused
3025 functions. Delete unused/unnecessary arguments to some functions.
3026 Group static vars together. Abort for bad errors until we have
3027 error code propogation working. Work on spacing and indention.
3028 Add FIXMEs for unresolved problems. Use enums rather than
3029 #defines for lots of things. Merge two functions which build
3030 linker stubs into a single function (so they can easily share a
3031 ton of common code).
3033 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
3035 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
3036 avoid depending upon right shifts of signed numbers, and to

3959 The sparc (and possibly other?) NLM format requires a different
3960 way to write exports, so add a write_export field to the backend
3961 data (and set it to NULL for everything but the sparc).

5237 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
5238 MY_bfd_seclet_link): Define.
5239 (MY_bfd_reloc_type_lookup): Rename from
5240 MY_reloc_howto_type_lookup.
5241 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
5242 (MY(vec)): Use JUMP_TABLE rather than listing functions.
5243 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
5244 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
5245 terms of MY, because that causes a recusive invocation of CAT when
5246 expanded within JUMP_TABLE, and ANSI compilers don't expand
5248 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
5249 MY_reloc_howto_type_lookup, and don't define in terms of MY.
5250 (MY_canonicalize_reloc): Don't define in terms of MY.
5251 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
5252 than listing functions.
