2584 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2586 * som.h (som_copyable_section_data_struct): New structure
2587 containing all the private section information which needs
2588 to be copied from input section to output section during
2590 (som_section_data_struct): Remove several fields now in
2591 som_copyable_section_data_struct. Make the space and
2592 subspace dictionaries be pointers (to save space when
2593 only reading objects).
2595 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2596 some references changed. Allocate a copyable data stucture if
2597 none exists. Store info into the copyable data structure.
2598 (bfd_som_set_subsection_attributes): Likewise.
2599 (som_is_space, som_is_subspace, som_is_container): New functions.
2600 Use these instead of directly accessing private data.
2601 (som_prep_headers): Allocate space and subspace headers here.
2602 Fill in some fields in the space/subspace headers from the
2604 (som_bfd_copy_private_section_data): Only copy the stuff
2605 that we really need to make objcopy and strip work. Allocate
2606 the copy_data structure for the output bfd before copying.
2608 * som.h (struct som_exec_data): New structure to hold exec
2609 info that must be preserved when running objcopy/strip.
2610 (struct somdata): Add new "exec_data" field and accessor
2611 macro. Add some comments on how the various fields are used.
2612 (som_section_data_struct): Make is_space and is_subspace bitfields.
2613 Delete unused subspace_index. All references now use the
2614 target_index field within the section structure itself.
2616 * som.c (make_unique_section): Delete unused declaration.
2617 (som_bfd_copy_private_bfd_data): New function.
2618 (som_object_setup): Allocate space for and save exec information
2619 that needs to be copied during objcopy/strip.
2620 (som_mkobject): Do not allocate space for a file header here.
2621 It is not used when only reading SOM objects.
2622 (som_prep_headers): Allocate space for and attach a file header
2623 to the output bfd. For executables, use the saved system_id
2624 value rather than trying to guess the right value. Do not abort
2625 wwhen setting file_hdr->entry* for executables.
2626 (som_begin_writing): For executables, set the exec_entry and
2628 (som_copy_private_backend_section_data): Always return a value.
2630 * libhppa.h (PA_PAGESIZE): Define.
2632 * som.c (SOM_ALIGN): Define.
2633 (som_begin_writing): If writing an executable, initialize all
2634 fields in the exec header to zero. Update fields in the exec
2635 header as sizes of loadable subspaces are computed. Carefully
2636 preserve alignments when building executables. Actually write the
2637 exec after all the fields are filled in.
2639 * Better long-filename handling. Reads SOM ABI compliant extended
2640 names, but doesn't quite write compliant extended names yet.
2641 * som.c (som_slurp_extended_name_table): Delete function. The
2642 generic code will handle things correctly.
2643 (som_slurp_armap): Seek to the beginning of the next member.
2644 (normalize): New function.
2645 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2646 name table into account when computing the file offsets in the
2647 SOM dictionary. Make sure to align to an even boundary.
2648 (som_write_armap): Initialize the checksum to zero.
2649 (ar_maxchars): Fix. Opps.
2651 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2653 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2654 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2656 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2658 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2659 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2660 * bfd-in2.h: Regenerated.
2662 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2663 this was also named trad_unix_bfd_copy_private_bfd_data.
2665 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2667 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2668 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2669 returns NULL, it is not an error. It's possible that some of
2670 these checks are not necessary (because the size can never be
2671 zero), but putting in the checks is the conservative thing to do
2672 in light of the fact that some of these malloc calls replaced
2673 unchecked alloca calls, in which a zero argument would work fine.
2675 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2677 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2678 duplicate definition.
2679 (osf_core_bfd_is_local_label): Define.
2681 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2682 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2683 failure indication, it merely means there are no relocs.
2685 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2686 after NAME, since SunOS /bin/cc can't handle it.
2688 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2690 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2691 From sukes@glue.umd.edu (Tasuki Hirata).
2693 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2695 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2696 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2697 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2699 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2701 * som.c (som_prep_for_fixups): Detect section symbols based
2702 on either the lack of private data or the symbol flags. Do not
2703 munge section symbol names anymore -- they no longer confuse GDB.
2704 (som_begin_writing): Leave space for an exec header if writing
2706 (som_slurp_symbol_table): Recognize both forms of section symbol
2707 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2708 section symbols to be the name of the section they represent.
2709 Debugging symbols begin with "L$0\001", not just "L$".
2711 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2713 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2715 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2716 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2717 and bfd_is_local_label.
2719 * targets.c: Add new entries to the bfd_target structure.
2721 * bfd.c (bfd_copy_private_bfd_data): New definition.
2723 * section.c (bfd_copy_private_section_data): New definition.

2727 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2729 * libbfd.c (bfd_generic_is_local_label): New function.
2731 * *-core.c: Provide default definitions for new functions in
2732 the target vector which all point to bfd_false.
2734 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2735 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2736 Default new vectors for copying private backend data to bfd_true.
2737 Default new vector for determining if a symbol is a local label
2738 to bfd_generic_is_local_label.
2740 * som.c (som_bfd_copy_private_section_data): New function.
2741 (som_bfd_is_local_label): New function.
2742 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2744 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2746 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2748 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2750 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2753 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2754 Indent some of them to GNU standards.
2756 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2757 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2758 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2759 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2760 Update copyright years.
2762 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2764 * som.c (som_prep_for_fixups): A relocation involving the section
2765 symbol for the *ABS* section is really a relocation involving
2767 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2768 undefined symbols. Correctly distinguish between debugger symbols
2769 and section symbols.
2771 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2772 for spaces and subspaces.
2774 * som.c (som_bfd_count_ar_symbols): Fix typo.
2776 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2777 HAS_RELOC based on the object's magic number.
2778 (make_unique_section): Delete function. BFD and its users are
2779 prepared to handle multiple sections with the same name.
2780 (setup_sections): Allocate space on the BFD's obstack to hold
2781 section names. Use bfd_make_setion_anyway rather than the
2782 obsolete make_unique_section.
2783 (som_prep_headers): Choose the correct SOM magic number based
2785 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.

2799 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2800 is always located at the start of the data section to allow
2801 recovery of the dynamic info from a stripped executable.
2802 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2805 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2807 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2808 cruft (like the #pragma alloca for AIX).
2809 In addition to that problem, the C alloca calls xmalloc, which
2810 means checking for being out of memory can't work right. The
2811 following changes remove all uses of alloca from BFD.
2812 * hosts/solaris2.h: Remove alloca cruft.
2813 * som.c: Replace alloca with a fixed size auto array.
2814 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
2815 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
2816 sunos.c: Replace alloca with malloc and appropriate error checking and
2818 * linker.c: Replace alloca with obstack_alloc.
2819 * libbfd.h: Rebuilt.
2821 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2823 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2826 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2828 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2829 Elf*_Off typedefs by their expansion, the typedefs have been
2830 removed from include/elf/internal.h.
2831 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2832 SHT_PROGBITS section.
2834 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2836 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

2842 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2843 return from bfd_seek indicates an error.
2844 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2845 TRAD_CORE_STACK_OFFSET.
2846 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2847 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2849 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2851 * som.[ch]: Do not include libhppa.h in som.c, instead include
2854 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2855 include it in elf32-hppa.h.
2857 * som.c (log2): Return -1 on error rather than aborting.
2858 (setup_sections): Bubble up an error from log2.
2860 * Changes to make HP C compiler happy in both traditional
2862 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2864 (bfd_som_set_section_attributes): Use unsigned int rather than
2865 unsigned char to avoid GNU-C extensions.
2866 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2867 or failure rather than aborting on failure.
2869 * som.h (bfd_som_set_section_attributes): Fix prototype to match
2871 (bfd_som_attach_aux_hdr): Add prototype.
2872 (hppa_som-gen_reloc_type): Likewise.
2874 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2875 (hppa_look_for_stubs_in_section): Do not return false on failure
2876 until rest of code is ready to handle it. Abort for now.

2902 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2903 right in the original relocation and the stub's relocation.

2906 unused symbols argument.
2908 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

2910 Set reloc->sym_ptr_ptr appropriately.
2911 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2912 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2913 argument. Use the output symbols when canonicalizing the relocs,
2914 creating them if necessary.
2916 * linker.c (_bfd_generic_link_output_symbols): Do not
2917 rebuild/clobber the output symbols if they already exist.
2919 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
2921 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that

2931 PARAMize and staticize rest of functions. Delete unused
2932 functions. Delete unused/unnecessary arguments to some functions.
2933 Group static vars together. Abort for bad errors until we have
2934 error code propogation working. Work on spacing and indention.
2935 Add FIXMEs for unresolved problems. Use enums rather than
2936 #defines for lots of things. Merge two functions which build
2937 linker stubs into a single function (so they can easily share a
2938 ton of common code).
2940 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2942 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2943 avoid depending upon right shifts of signed numbers, and to
2944 correct handling of src_mask with lower bits zero.
2946 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.

2974 * elf32-hppa.h (elf_hppa_tc_symbol): Add new arguments.
2975 (elf_hppa_tc_make_sections): Likewise.
2976 (elf_hppa_final_processing): Add extern decl.
2978 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
2979 comments. PARAMize some static functions. Delete unused functions.
2980 Delete unused/unnecessary arguments to many functions. Group
2981 static vars together. Collapse common case statements together
2982 in many places. Use default case when possible instead of listing
2983 each case separately. Abort for bad errors until we get error
2984 code propogation working. Work on spacing and indention problems.
2985 Add FIXMEs for some unresolved problems. Delete hopelessly broken
2986 COMPLEX relocation support (it's never used anyway).
2987 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
2988 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
2989 (elf_hppa_tc_make_sections): Likewise.

3002 Fri Feb 25 13:19:04 1994 Ted Lemon (mellon@pepper.ncd.com)
3004 * bfd.c (bfd_get_gp_size): Can't return gp value on an archive.

3030 * elfcode.h (alloca): Delete declaration.
3032 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
3033 number rather than HP9000S800_ID. Note som.c is careful
3034 to make sure CPU_PA_RISC1_0 is always defined.
3036 Mon Feb 21 10:12:02 1994 Stan Shebs (shebs@andros.cygnus.com)
3038 * Makefile.in (targets.o, archures.o): Use ALL_CFLAGS to supply

3836 use get_value to get the symbol value and check for undefined
3838 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
3839 undefined, look it up in the linker hash table.
3841 * aoutx.h (translate_symbol_table): The string index 0 has a

3866 The sparc (and possibly other?) NLM format requires a different
3867 way to write exports, so add a write_export field to the backend
3868 data (and set it to NULL for everything but the sparc).
