2371
2372 * som.c (som_get_section_contents): New function. Do not try
2373 to actually read data from a section that doesn't have either
2374 SEC_LOAD or SEC_DEBUGGING set (eg $BSS$) just return true.
2375
2376 * libbfd.c (bfd_read): Set bfd_error as appropriate for a short
2377 read. (bfd_error_system_call or bfd_error_file_truncated).
2378
2379 * som.c: Do not blindly set bfd_error_system_call after a
2380 failing bfd_read, bfd_write, or bfd_seek. In a few places
2381 (like som_object_p) override the error status set by bfd_read.
2382
2383 * aix386-core.c, aout-encap,c archive.c, bout.c: Likewise.
2384 * coff-rs6000.c, coffgen.c ecoff.c, elf.c: Likewise.

2419 from undefined to section. Change handling of PC relative relocs:
2420 if against a section, they are correct in the object file, if
2421 against an external symbol they are pcrel_offset.
2422 (mips_relax_section): New function.

2514 * elf32-mips.c (mips_elf_final_link): Account for link_order
2515 relocs when allocating space for relocations. Set SEC_RELOC flag
2516 for any section which has relocs. Handle link_order relocs in
2517 link_order loop. Use _bfd_generic_link_add_symbols_collect for
2518 add_symbls entry point.
2519
2520 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before

2524 * linker.c (_bfd_default_link_order): Handle bfd_data_link_order.
2525

2527 generic_link_add_symbols.
2528 (_bfd_generic_link_add_symbols_collect): New function, like
2529 _bfd_generic_link_add_symbols but also collect constructors and
2530 destructors by name as collect2 does.

2543 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2544
2545 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
2546 for first character in an extended name.

2548 "//" as the name of the special archive member holding the
2549 extended name table.
2550
2551 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

2556 from call to _bfd_generic_link_add_one_symbol.
2557 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.

2559 instead of bitsize to add_to_set call back.
2560 (_bfd_generic_final_link): Account for link_order relocs when
2561 allocating space for relocations. Handle them in link_order loop.
2562 (_bfd_generic_reloc_link_order): New function.
2563 (_bfd_default_link_order): If a reloc_link_order is seen here,
2564 abort.
2565 (_bfd_count_link_order_relocs): New function.

2572 call to _bfd_generic_link_add_one_symbol.
2573 (NAME(aout,final_link)): Account for link_order relocs when
2574 allocating space for relocations. Handle them after handling all
2575 input BFDs.
2576 (aout_link_reloc_link_order): New function.

2585 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
2586 BFD_RELOC_CTOR.

2595
2596 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2597
2598 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2599
2600 * som.c (bfd_section_from_som_symbol): Only to do the value
2601 comparison for function symbols within executables.
2602
2603 * som.c (bfd_section_from_som_symbol): Renamed from
2604 som_section_from_subspace_index. Pass in a native SOM symbol.
2605 For executables, iterate through the sections to find out
2606 which contains the symbol's address rather than using the
2607 symbol_info field. (symbol_info has a different meaning for
2608 dynamicly linked executables.)
2609
2610 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2611 bfd_zmalloc.
2612
2613 * som.c (som_begin_writing): Fix braino (one call to align
2614 space/subspace data was done unconditionally rather than
2615 just for executables.)
2616
2617 * som.c (som_begin_writing): Align text in all executables to
2618 make HPUX kernel happy. Fixes strip/objcopy for shared
2619 executables.
2620
2621 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2622
2623 * som.c (som_begin_writing): Account for alignment needs of
2624 subspaces too when writing executables. Never request a negative
2625 bss size. Fixes some problems with demand paged executables,
2626 still having problems with pure executables and shared executables.
2627
2628 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2629
2630 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2631 bfd_zalloc for rawptr, because later on we may call free, not
2632 bfd_release, on it.
2633
2634 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2635 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2636 * cisco-core.c: New file.
2637 * Makefile.in: Change accordingly.
2638 * configure.in: Recognize cisco_core_vec.
2639 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2640 * targets.c: Add cisco_core_vec.
2641 * bfd-in2.h: Rebuilt.
2642
2643 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2644
2645 * som.h (som_copyable_section_data_struct): New structure
2646 containing all the private section information which needs
2647 to be copied from input section to output section during
2648 objcopy or strip.
2649 (som_section_data_struct): Remove several fields now in
2650 som_copyable_section_data_struct. Make the space and
2651 subspace dictionaries be pointers (to save space when
2652 only reading objects).
2653
2654 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2655 some references changed. Allocate a copyable data stucture if
2656 none exists. Store info into the copyable data structure.
2657 (bfd_som_set_subsection_attributes): Likewise.
2658 (som_is_space, som_is_subspace, som_is_container): New functions.
2659 Use these instead of directly accessing private data.
2660 (som_prep_headers): Allocate space and subspace headers here.
2661 Fill in some fields in the space/subspace headers from the
2662 copyable data.
2663 (som_bfd_copy_private_section_data): Only copy the stuff
2664 that we really need to make objcopy and strip work. Allocate
2665 the copy_data structure for the output bfd before copying.
2666
2667 * som.h (struct som_exec_data): New structure to hold exec
2668 info that must be preserved when running objcopy/strip.
2669 (struct somdata): Add new "exec_data" field and accessor
2670 macro. Add some comments on how the various fields are used.
2671 (som_section_data_struct): Make is_space and is_subspace bitfields.
2672 Delete unused subspace_index. All references now use the
2673 target_index field within the section structure itself.
2674
2675 * som.c (make_unique_section): Delete unused declaration.
2676 (som_bfd_copy_private_bfd_data): New function.
2677 (som_object_setup): Allocate space for and save exec information
2678 that needs to be copied during objcopy/strip.
2679 (som_mkobject): Do not allocate space for a file header here.
2680 It is not used when only reading SOM objects.
2681 (som_prep_headers): Allocate space for and attach a file header
2682 to the output bfd. For executables, use the saved system_id
2683 value rather than trying to guess the right value. Do not abort
2684 wwhen setting file_hdr->entry* for executables.
2685 (som_begin_writing): For executables, set the exec_entry and
2686 exec_flags fields.
2687 (som_copy_private_backend_section_data): Always return a value.
2688
2689 * libhppa.h (PA_PAGESIZE): Define.
2690
2691 * som.c (SOM_ALIGN): Define.
2692 (som_begin_writing): If writing an executable, initialize all
2693 fields in the exec header to zero. Update fields in the exec
2694 header as sizes of loadable subspaces are computed. Carefully
2695 preserve alignments when building executables. Actually write the
2696 exec after all the fields are filled in.
2697
2698 * Better long-filename handling. Reads SOM ABI compliant extended
2699 names, but doesn't quite write compliant extended names yet.
2700 * som.c (som_slurp_extended_name_table): Delete function. The
2701 generic code will handle things correctly.
2702 (som_slurp_armap): Seek to the beginning of the next member.
2703 (normalize): New function.
2704 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2705 name table into account when computing the file offsets in the
2706 SOM dictionary. Make sure to align to an even boundary.
2707 (som_write_armap): Initialize the checksum to zero.
2708 (ar_maxchars): Fix. Opps.
2709
2710 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2711
2712 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2713 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2714
2715 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2716
2717 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2718 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2719 * bfd-in2.h: Regenerated.
2720
2721 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2722 this was also named trad_unix_bfd_copy_private_bfd_data.
2723
2724 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2725
2726 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2727 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2728 returns NULL, it is not an error. It's possible that some of
2729 these checks are not necessary (because the size can never be
2730 zero), but putting in the checks is the conservative thing to do
2731 in light of the fact that some of these malloc calls replaced
2732 unchecked alloca calls, in which a zero argument would work fine.
2733
2734 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2735
2736 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2737 duplicate definition.
2738 (osf_core_bfd_is_local_label): Define.
2739
2740 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2741 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2742 failure indication, it merely means there are no relocs.
2743
2744 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2745 after NAME, since SunOS /bin/cc can't handle it.
2746
2747 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2748
2749 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2750 From sukes@glue.umd.edu (Tasuki Hirata).
2751
2752 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2753
2754 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2755 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2756 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2757
2758 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2759
2760 * som.c (som_prep_for_fixups): Detect section symbols based
2761 on either the lack of private data or the symbol flags. Do not
2762 munge section symbol names anymore -- they no longer confuse GDB.
2763 (som_begin_writing): Leave space for an exec header if writing
2764 an executable.
2765 (som_slurp_symbol_table): Recognize both forms of section symbol
2766 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2767 section symbols to be the name of the section they represent.

2865
2866 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2867 cruft (like the #pragma alloca for AIX).
2868 In addition to that problem, the C alloca calls xmalloc, which

2965 unused symbols argument.
2966
2967 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather

2994 Add FIXMEs for unresolved problems. Use enums rather than
2995 #defines for lots of things. Merge two functions which build
2996 linker stubs into a single function (so they can easily share a

3634
3635 * srec.c (srec_write_record): Put CONST keyword for "src" before
3636 "unsigned", some compilers don't like it after "unsigned".
3637 * libcoff.h, libcoff-in.h (bfd_perform_slip): Rename "value" to
3638 "val" in prototype declaration because some compilers don't like
3639 arguments whose names are the same as types.

3662 STYP_INFO for the type of a section named .debug.
3663 (coff_add_missing_symbols): Don't define if RS6000COFF_C.
3664 (coff_write_object_contents): If RS6000COFF_C, don't call

3667 entry has type STY_LD change the x_scnlen into a pointer to a
3668 symbol and set fix_scnlen. Also, for a C_BSTAT symbol, change the
3669 value into a pointer to a symbol and set fix_value.
3670 * libcoff.h: Rebuilt.

3682 .debug section.
3683 (coff_get_normalized_symtab): Clear new fix_value and fix_scnlen

3744 accordingly.
3745 * libcoff.h: Rebuilt.
3746 * coffswap.h (coff_swap_aux_in, coff_swap_aux_out): Accept new
3747 arguments. If RS6000COFF_C, only treat C_EXT and C_HIDEXT

3753
3754 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
3755 (only testing for m68k and vax at the moment); do verify that the
3756 preprocessor didn't trash the arch name inside the string version.
3757 Don't print out "pagesize =" line that prevents output from
3758 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
3759 results.

3785
3786 * som.c, som.h (bfd_som_set_section_attributes,
3787 bfd_som_set_subsection_attributes): Change parameters from char

3799
3800 * archive.c (do_slurp_bsd_armap, bfd_slurp_bsd_armap_f2): Do not
3801 try to overlay the internal carsyms on the external symdefs. That
3802 can not work if the size of a host pointer is larger than 4 bytes.

3898 undefined, look it up in the linker hash table.
3899
3900 * aoutx.h (translate_symbol_table): The string index 0 has a

3925 The sparc (and possibly other?) NLM format requires a different
3926 way to write exports, so add a write_export field to the backend
3927 data (and set it to NULL for everything but the sparc).
3928

4169 * configure.in (nlm32_alpha_vec): Set target64 to true.
4170
4171 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are

5210 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
5211 terms of MY, because that causes a recusive invocation of CAT when
