2592 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2594 * som.c (som_begin_writing): Account for alignment needs of
2595 subspaces too when writing executables. Never request a negative
2596 bss size. Fixes some problems with demand paged executables,
2597 still having problems with pure executables and shared executables.
2599 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2601 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2602 bfd_zalloc for rawptr, because later on we may call free, not
2605 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2606 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2607 * cisco-core.c: New file.
2608 * Makefile.in: Change accordingly.
2609 * configure.in: Recognize cisco_core_vec.
2610 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2611 * targets.c: Add cisco_core_vec.
2612 * bfd-in2.h: Rebuilt.
2614 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2616 * som.h (som_copyable_section_data_struct): New structure
2617 containing all the private section information which needs
2618 to be copied from input section to output section during
2620 (som_section_data_struct): Remove several fields now in
2621 som_copyable_section_data_struct. Make the space and
2622 subspace dictionaries be pointers (to save space when
2623 only reading objects).
2625 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2626 some references changed. Allocate a copyable data stucture if
2627 none exists. Store info into the copyable data structure.
2628 (bfd_som_set_subsection_attributes): Likewise.
2629 (som_is_space, som_is_subspace, som_is_container): New functions.
2630 Use these instead of directly accessing private data.
2631 (som_prep_headers): Allocate space and subspace headers here.
2632 Fill in some fields in the space/subspace headers from the
2634 (som_bfd_copy_private_section_data): Only copy the stuff
2635 that we really need to make objcopy and strip work. Allocate
2636 the copy_data structure for the output bfd before copying.
2638 * som.h (struct som_exec_data): New structure to hold exec
2639 info that must be preserved when running objcopy/strip.
2640 (struct somdata): Add new "exec_data" field and accessor
2641 macro. Add some comments on how the various fields are used.
2642 (som_section_data_struct): Make is_space and is_subspace bitfields.
2643 Delete unused subspace_index. All references now use the
2644 target_index field within the section structure itself.
2646 * som.c (make_unique_section): Delete unused declaration.
2647 (som_bfd_copy_private_bfd_data): New function.
2648 (som_object_setup): Allocate space for and save exec information
2649 that needs to be copied during objcopy/strip.
2650 (som_mkobject): Do not allocate space for a file header here.
2651 It is not used when only reading SOM objects.
2652 (som_prep_headers): Allocate space for and attach a file header
2653 to the output bfd. For executables, use the saved system_id
2654 value rather than trying to guess the right value. Do not abort
2655 wwhen setting file_hdr->entry* for executables.
2656 (som_begin_writing): For executables, set the exec_entry and
2658 (som_copy_private_backend_section_data): Always return a value.
2660 * libhppa.h (PA_PAGESIZE): Define.
2662 * som.c (SOM_ALIGN): Define.
2663 (som_begin_writing): If writing an executable, initialize all
2664 fields in the exec header to zero. Update fields in the exec
2665 header as sizes of loadable subspaces are computed. Carefully
2666 preserve alignments when building executables. Actually write the
2667 exec after all the fields are filled in.
2669 * Better long-filename handling. Reads SOM ABI compliant extended
2670 names, but doesn't quite write compliant extended names yet.
2671 * som.c (som_slurp_extended_name_table): Delete function. The
2672 generic code will handle things correctly.
2673 (som_slurp_armap): Seek to the beginning of the next member.
2674 (normalize): New function.
2675 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2676 name table into account when computing the file offsets in the
2677 SOM dictionary. Make sure to align to an even boundary.
2678 (som_write_armap): Initialize the checksum to zero.
2679 (ar_maxchars): Fix. Opps.
2681 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2683 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2684 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2686 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2688 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2689 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2690 * bfd-in2.h: Regenerated.
2692 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2693 this was also named trad_unix_bfd_copy_private_bfd_data.
2695 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2697 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2698 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2699 returns NULL, it is not an error. It's possible that some of
2700 these checks are not necessary (because the size can never be
2701 zero), but putting in the checks is the conservative thing to do
2702 in light of the fact that some of these malloc calls replaced
2703 unchecked alloca calls, in which a zero argument would work fine.
2705 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2707 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2708 duplicate definition.
2709 (osf_core_bfd_is_local_label): Define.
2711 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2712 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2713 failure indication, it merely means there are no relocs.
2715 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2716 after NAME, since SunOS /bin/cc can't handle it.
2718 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2720 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2721 From sukes@glue.umd.edu (Tasuki Hirata).
2723 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2725 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2726 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2727 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2729 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2731 * som.c (som_prep_for_fixups): Detect section symbols based
2732 on either the lack of private data or the symbol flags. Do not
2733 munge section symbol names anymore -- they no longer confuse GDB.
2734 (som_begin_writing): Leave space for an exec header if writing
2736 (som_slurp_symbol_table): Recognize both forms of section symbol
2737 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2738 section symbols to be the name of the section they represent.
2739 Debugging symbols begin with "L$0\001", not just "L$".
2741 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2743 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2745 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2746 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2747 and bfd_is_local_label.
2749 * targets.c: Add new entries to the bfd_target structure.
2751 * bfd.c (bfd_copy_private_bfd_data): New definition.
2753 * section.c (bfd_copy_private_section_data): New definition.
2755 * syms.c (bfd_is_local_label): New definition.
2757 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2759 * libbfd.c (bfd_generic_is_local_label): New function.
2761 * *-core.c: Provide default definitions for new functions in
2762 the target vector which all point to bfd_false.
2764 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2765 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2766 Default new vectors for copying private backend data to bfd_true.
2767 Default new vector for determining if a symbol is a local label
2768 to bfd_generic_is_local_label.
2770 * som.c (som_bfd_copy_private_section_data): New function.
2771 (som_bfd_is_local_label): New function.
2772 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2774 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2776 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2778 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2780 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2783 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2784 Indent some of them to GNU standards.
2786 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2787 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2788 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2789 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2790 Update copyright years.
2792 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2794 * som.c (som_prep_for_fixups): A relocation involving the section
2795 symbol for the *ABS* section is really a relocation involving
2797 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2798 undefined symbols. Correctly distinguish between debugger symbols
2799 and section symbols.
2801 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2802 for spaces and subspaces.
2804 * som.c (som_bfd_count_ar_symbols): Fix typo.
2806 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2807 HAS_RELOC based on the object's magic number.
2808 (make_unique_section): Delete function. BFD and its users are
2809 prepared to handle multiple sections with the same name.
2810 (setup_sections): Allocate space on the BFD's obstack to hold
2811 section names. Use bfd_make_setion_anyway rather than the
2812 obsolete make_unique_section.
2813 (som_prep_headers): Choose the correct SOM magic number based
2815 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2817 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2819 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2820 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2821 * Makefile.in, configure.in: Corresponding changes.

2829 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2830 is always located at the start of the data section to allow
2831 recovery of the dynamic info from a stripped executable.
2832 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2835 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2837 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2838 cruft (like the #pragma alloca for AIX).
2839 In addition to that problem, the C alloca calls xmalloc, which
2840 means checking for being out of memory can't work right. The
2841 following changes remove all uses of alloca from BFD.
2842 * hosts/solaris2.h: Remove alloca cruft.
2843 * som.c: Replace alloca with a fixed size auto array.
2844 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
2845 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
2846 sunos.c: Replace alloca with malloc and appropriate error checking and
2848 * linker.c: Replace alloca with obstack_alloc.
2849 * libbfd.h: Rebuilt.
2851 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2853 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2856 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2858 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2859 Elf*_Off typedefs by their expansion, the typedefs have been
2860 removed from include/elf/internal.h.
2861 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2862 SHT_PROGBITS section.
2864 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2866 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2872 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2873 return from bfd_seek indicates an error.
2874 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2875 TRAD_CORE_STACK_OFFSET.
2876 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2877 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2879 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2881 * som.[ch]: Do not include libhppa.h in som.c, instead include
2884 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2885 include it in elf32-hppa.h.
2887 * som.c (log2): Return -1 on error rather than aborting.
2888 (setup_sections): Bubble up an error from log2.
2890 * Changes to make HP C compiler happy in both traditional
2892 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2894 (bfd_som_set_section_attributes): Use unsigned int rather than
2895 unsigned char to avoid GNU-C extensions.
2896 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2897 or failure rather than aborting on failure.
2899 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2901 (bfd_som_attach_aux_hdr): Add prototype.
2902 (hppa_som-gen_reloc_type): Likewise.

2931 action in case where caller specified no argument relocation.
2932 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2933 right in the original relocation and the stub's relocation.
2935 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
2936 unused symbols argument.
2938 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
2939 than asymbol * for original target symbol. All callers changed.
2940 Set reloc->sym_ptr_ptr appropriately.
2941 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2942 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2943 argument. Use the output symbols when canonicalizing the relocs,
2944 creating them if necessary.
2946 * linker.c (_bfd_generic_link_output_symbols): Do not
2947 rebuild/clobber the output symbols if they already exist.
2949 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
2951 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
2952 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
2953 * bfd-in2.h: Rebuilt.
2955 * srec.c (hex_value): Always set to a size of 256 bytes.
2956 (srec_init): Cosmetic changes.
2958 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2960 * elf32-hppa.c: Second half of major cleanup. More comments,
2961 PARAMize and staticize rest of functions. Delete unused
2962 functions. Delete unused/unnecessary arguments to some functions.
2963 Group static vars together. Abort for bad errors until we have
2964 error code propogation working. Work on spacing and indention.
2965 Add FIXMEs for unresolved problems. Use enums rather than
2966 #defines for lots of things. Merge two functions which build
2967 linker stubs into a single function (so they can easily share a
2968 ton of common code).
2970 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2972 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2973 avoid depending upon right shifts of signed numbers, and to
2974 correct handling of src_mask with lower bits zero.
2976 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
2977 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

3002 * libhppa.h (hppa_rebuild_insn): Moved here from elf32-hppa.c.
3004 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
3005 (elf_hppa_tc_make_sections): Likewise.
3006 (elf_hppa_final_processing): Add extern decl.
3008 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
3009 comments. PARAMize some static functions. Delete unused functions.
3010 Delete unused/unnecessary arguments to many functions. Group
3011 static vars together. Collapse common case statements together
3012 in many places. Use default case when possible instead of listing
3013 each case separately. Abort for bad errors until we get error
3014 code propogation working. Work on spacing and indention problems.
3015 Add FIXMEs for some unresolved problems. Delete hopelessly broken
3016 COMPLEX relocation support (it's never used anyway).
3017 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
3018 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
3019 (elf_hppa_tc_make_sections): Likewise.
3021 * format.c (bfd_check_format_matches): Initialize matching_vector
3022 to keep gcc -Wall quiet.

3032 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
3034 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

3866 use get_value to get the symbol value and check for undefined
3868 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
3869 undefined, look it up in the linker hash table.
3871 * aoutx.h (translate_symbol_table): The string index 0 has a

3896 The sparc (and possibly other?) NLM format requires a different
3897 way to write exports, so add a write_export field to the backend
3898 data (and set it to NULL for everything but the sparc).
