2588 dynamicly linked executables.)
2590 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2593 * som.c (som_begin_writing): Fix braino (one call to align
2594 space/subspace data was done unconditionally rather than
2595 just for executables.)
2597 * som.c (som_begin_writing): Align text in all executables to
2598 make HPUX kernel happy. Fixes strip/objcopy for shared
2601 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2603 * som.c (som_begin_writing): Account for alignment needs of
2604 subspaces too when writing executables. Never request a negative
2605 bss size. Fixes some problems with demand paged executables,
2606 still having problems with pure executables and shared executables.
2608 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2610 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2611 bfd_zalloc for rawptr, because later on we may call free, not
2614 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2615 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2616 * cisco-core.c: New file.
2617 * Makefile.in: Change accordingly.
2618 * configure.in: Recognize cisco_core_vec.
2619 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2620 * targets.c: Add cisco_core_vec.
2621 * bfd-in2.h: Rebuilt.
2623 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2625 * som.h (som_copyable_section_data_struct): New structure
2626 containing all the private section information which needs
2627 to be copied from input section to output section during
2629 (som_section_data_struct): Remove several fields now in
2630 som_copyable_section_data_struct. Make the space and
2631 subspace dictionaries be pointers (to save space when
2632 only reading objects).
2634 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2635 some references changed. Allocate a copyable data stucture if
2636 none exists. Store info into the copyable data structure.
2637 (bfd_som_set_subsection_attributes): Likewise.
2638 (som_is_space, som_is_subspace, som_is_container): New functions.
2639 Use these instead of directly accessing private data.
2640 (som_prep_headers): Allocate space and subspace headers here.
2641 Fill in some fields in the space/subspace headers from the
2643 (som_bfd_copy_private_section_data): Only copy the stuff
2644 that we really need to make objcopy and strip work. Allocate
2645 the copy_data structure for the output bfd before copying.
2647 * som.h (struct som_exec_data): New structure to hold exec
2648 info that must be preserved when running objcopy/strip.
2649 (struct somdata): Add new "exec_data" field and accessor
2650 macro. Add some comments on how the various fields are used.
2651 (som_section_data_struct): Make is_space and is_subspace bitfields.
2652 Delete unused subspace_index. All references now use the
2653 target_index field within the section structure itself.
2655 * som.c (make_unique_section): Delete unused declaration.
2656 (som_bfd_copy_private_bfd_data): New function.
2657 (som_object_setup): Allocate space for and save exec information
2658 that needs to be copied during objcopy/strip.
2659 (som_mkobject): Do not allocate space for a file header here.
2660 It is not used when only reading SOM objects.
2661 (som_prep_headers): Allocate space for and attach a file header
2662 to the output bfd. For executables, use the saved system_id
2663 value rather than trying to guess the right value. Do not abort
2664 wwhen setting file_hdr->entry* for executables.
2665 (som_begin_writing): For executables, set the exec_entry and
2667 (som_copy_private_backend_section_data): Always return a value.
2669 * libhppa.h (PA_PAGESIZE): Define.
2671 * som.c (SOM_ALIGN): Define.
2672 (som_begin_writing): If writing an executable, initialize all
2673 fields in the exec header to zero. Update fields in the exec
2674 header as sizes of loadable subspaces are computed. Carefully
2675 preserve alignments when building executables. Actually write the
2676 exec after all the fields are filled in.
2678 * Better long-filename handling. Reads SOM ABI compliant extended
2679 names, but doesn't quite write compliant extended names yet.
2680 * som.c (som_slurp_extended_name_table): Delete function. The
2681 generic code will handle things correctly.
2682 (som_slurp_armap): Seek to the beginning of the next member.
2683 (normalize): New function.
2684 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2685 name table into account when computing the file offsets in the
2686 SOM dictionary. Make sure to align to an even boundary.
2687 (som_write_armap): Initialize the checksum to zero.
2688 (ar_maxchars): Fix. Opps.
2690 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2692 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2693 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2695 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2697 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2698 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2699 * bfd-in2.h: Regenerated.
2701 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2702 this was also named trad_unix_bfd_copy_private_bfd_data.
2704 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2706 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2707 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2708 returns NULL, it is not an error. It's possible that some of
2709 these checks are not necessary (because the size can never be
2710 zero), but putting in the checks is the conservative thing to do
2711 in light of the fact that some of these malloc calls replaced
2712 unchecked alloca calls, in which a zero argument would work fine.
2714 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2716 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2717 duplicate definition.
2718 (osf_core_bfd_is_local_label): Define.
2720 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2721 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2722 failure indication, it merely means there are no relocs.
2724 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2725 after NAME, since SunOS /bin/cc can't handle it.
2727 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2729 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2730 From sukes@glue.umd.edu (Tasuki Hirata).
2732 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2734 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2735 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2736 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2738 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2740 * som.c (som_prep_for_fixups): Detect section symbols based
2741 on either the lack of private data or the symbol flags. Do not
2742 munge section symbol names anymore -- they no longer confuse GDB.
2743 (som_begin_writing): Leave space for an exec header if writing
2745 (som_slurp_symbol_table): Recognize both forms of section symbol
2746 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2747 section symbols to be the name of the section they represent.
2748 Debugging symbols begin with "L$0\001", not just "L$".
2750 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2752 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2754 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2755 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2756 and bfd_is_local_label.
2758 * targets.c: Add new entries to the bfd_target structure.
2760 * bfd.c (bfd_copy_private_bfd_data): New definition.
2762 * section.c (bfd_copy_private_section_data): New definition.
2764 * syms.c (bfd_is_local_label): New definition.
2766 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2768 * libbfd.c (bfd_generic_is_local_label): New function.
2770 * *-core.c: Provide default definitions for new functions in
2771 the target vector which all point to bfd_false.
2773 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2774 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2775 Default new vectors for copying private backend data to bfd_true.
2776 Default new vector for determining if a symbol is a local label
2777 to bfd_generic_is_local_label.
2779 * som.c (som_bfd_copy_private_section_data): New function.
2780 (som_bfd_is_local_label): New function.
2781 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2783 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2785 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2787 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2789 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2792 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2793 Indent some of them to GNU standards.
2795 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2796 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2797 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2798 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2799 Update copyright years.
2801 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2803 * som.c (som_prep_for_fixups): A relocation involving the section
2804 symbol for the *ABS* section is really a relocation involving
2806 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2807 undefined symbols. Correctly distinguish between debugger symbols
2808 and section symbols.
2810 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2811 for spaces and subspaces.
2813 * som.c (som_bfd_count_ar_symbols): Fix typo.
2815 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2816 HAS_RELOC based on the object's magic number.
2817 (make_unique_section): Delete function. BFD and its users are
2818 prepared to handle multiple sections with the same name.
2819 (setup_sections): Allocate space on the BFD's obstack to hold
2820 section names. Use bfd_make_setion_anyway rather than the
2821 obsolete make_unique_section.
2822 (som_prep_headers): Choose the correct SOM magic number based
2824 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2826 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2828 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2829 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2830 * Makefile.in, configure.in: Corresponding changes.
2832 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2834 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.

2838 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2839 is always located at the start of the data section to allow
2840 recovery of the dynamic info from a stripped executable.
2841 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2844 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2846 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2847 cruft (like the #pragma alloca for AIX).
2848 In addition to that problem, the C alloca calls xmalloc, which
2849 means checking for being out of memory can't work right. The
2850 following changes remove all uses of alloca from BFD.
2851 * hosts/solaris2.h: Remove alloca cruft.
2852 * som.c: Replace alloca with a fixed size auto array.
2853 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
2854 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
2855 sunos.c: Replace alloca with malloc and appropriate error checking and
2857 * linker.c: Replace alloca with obstack_alloc.
2858 * libbfd.h: Rebuilt.
2860 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2862 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2865 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2867 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2868 Elf*_Off typedefs by their expansion, the typedefs have been
2869 removed from include/elf/internal.h.
2870 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2871 SHT_PROGBITS section.
2873 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2875 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2881 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2882 return from bfd_seek indicates an error.
2883 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2884 TRAD_CORE_STACK_OFFSET.
2885 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2886 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2888 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2890 * som.[ch]: Do not include libhppa.h in som.c, instead include
2893 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2894 include it in elf32-hppa.h.
2896 * som.c (log2): Return -1 on error rather than aborting.
2897 (setup_sections): Bubble up an error from log2.
2899 * Changes to make HP C compiler happy in both traditional
2901 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2903 (bfd_som_set_section_attributes): Use unsigned int rather than
2904 unsigned char to avoid GNU-C extensions.
2905 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2906 or failure rather than aborting on failure.
2908 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2910 (bfd_som_attach_aux_hdr): Add prototype.
2911 (hppa_som-gen_reloc_type): Likewise.
2913 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2914 (hppa_look_for_stubs_in_section): Do not return false on failure
2915 until rest of code is ready to handle it. Abort for now.

2919 * bfd-in2.h: Rebuilt.
2921 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

2939 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
2940 action in case where caller specified no argument relocation.
2941 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2942 right in the original relocation and the stub's relocation.
2944 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
2945 unused symbols argument.
2947 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
2948 than asymbol * for original target symbol. All callers changed.
2949 Set reloc->sym_ptr_ptr appropriately.
2950 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2951 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2952 argument. Use the output symbols when canonicalizing the relocs,
2953 creating them if necessary.
2955 * linker.c (_bfd_generic_link_output_symbols): Do not
2956 rebuild/clobber the output symbols if they already exist.
2958 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
2960 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
2961 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
2962 * bfd-in2.h: Rebuilt.
2964 * srec.c (hex_value): Always set to a size of 256 bytes.
2965 (srec_init): Cosmetic changes.
2967 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2969 * elf32-hppa.c: Second half of major cleanup. More comments,
2970 PARAMize and staticize rest of functions. Delete unused
2971 functions. Delete unused/unnecessary arguments to some functions.
2972 Group static vars together. Abort for bad errors until we have
2973 error code propogation working. Work on spacing and indention.
2974 Add FIXMEs for unresolved problems. Use enums rather than
2975 #defines for lots of things. Merge two functions which build
2976 linker stubs into a single function (so they can easily share a
2977 ton of common code).
2979 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2981 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2982 avoid depending upon right shifts of signed numbers, and to
2983 correct handling of src_mask with lower bits zero.
2985 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
2986 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

2996 (section_from_elf_index): Make index argument unsigned.
2998 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
3000 * elfcode.h: Don't include assert.h.

3011 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
3013 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
3014 (elf_hppa_tc_make_sections): Likewise.
3015 (elf_hppa_final_processing): Add extern decl.
3017 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
3018 comments. PARAMize some static functions. Delete unused functions.
3019 Delete unused/unnecessary arguments to many functions. Group
3020 static vars together. Collapse common case statements together
3021 in many places. Use default case when possible instead of listing
3022 each case separately. Abort for bad errors until we get error
3023 code propogation working. Work on spacing and indention problems.
3024 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3025 COMPLEX relocation support (it's never used anyway).
3026 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3027 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3028 (elf_hppa_tc_make_sections): Likewise.
3030 * format.c (bfd_check_format_matches): Initialize matching_vector
3031 to keep gcc -Wall quiet.
3033 * elfcode.h (elf_slurp_reloca_table): Fix typo.

3036 not "sizeof (som_symbol_type *)".
3038 * elfcode.h (elf_get_symtab_upper_bound): Use "sizeof (asymbol *)"
3039 not "sizeof (asymbol"). Opps.
3041 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
3043 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

3871 the symbol value and check for undefined symbols.
3872 (get_value): If the symbol is undefined, look it up in the linker
3874 (b_out_get_relocated_section_contents): For PCREL24 and PCREL13
3875 use get_value to get the symbol value and check for undefined
3877 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
3878 undefined, look it up in the linker hash table.
3880 * aoutx.h (translate_symbol_table): The string index 0 has a

3905 The sparc (and possibly other?) NLM format requires a different
3906 way to write exports, so add a write_export field to the backend
3907 data (and set it to NULL for everything but the sparc).
