2362
2363 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2364 bfd_zalloc for rawptr, because later on we may call free, not
2365 bfd_release, on it.
2366
2367 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2368 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.

2383 som_copyable_section_data_struct. Make the space and
2384 subspace dictionaries be pointers (to save space when
2385 only reading objects).
2386
2387 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2388 some references changed. Allocate a copyable data stucture if
2389 none exists. Store info into the copyable data structure.
2390 (bfd_som_set_subsection_attributes): Likewise.
2391 (som_is_space, som_is_subspace, som_is_container): New functions.
2392 Use these instead of directly accessing private data.
2393 (som_prep_headers): Allocate space and subspace headers here.
2394 Fill in some fields in the space/subspace headers from the
2395 copyable data.
2396 (som_bfd_copy_private_section_data): Only copy the stuff
2397 that we really need to make objcopy and strip work. Allocate
2398 the copy_data structure for the output bfd before copying.
2399
2400 * som.h (struct som_exec_data): New structure to hold exec
2401 info that must be preserved when running objcopy/strip.
2402 (struct somdata): Add new "exec_data" field and accessor
2403 macro. Add some comments on how the various fields are used.
2404 (som_section_data_struct): Make is_space and is_subspace bitfields.
2405 Delete unused subspace_index. All references now use the
2406 target_index field within the section structure itself.
2407
2408 * som.c (make_unique_section): Delete unused declaration.
2409 (som_bfd_copy_private_bfd_data): New function.
2410 (som_object_setup): Allocate space for and save exec information
2411 that needs to be copied during objcopy/strip.
2412 (som_mkobject): Do not allocate space for a file header here.
2413 It is not used when only reading SOM objects.
2414 (som_prep_headers): Allocate space for and attach a file header
2415 to the output bfd. For executables, use the saved system_id
2416 value rather than trying to guess the right value. Do not abort
2417 wwhen setting file_hdr->entry* for executables.
2418 (som_begin_writing): For executables, set the exec_entry and
2419 exec_flags fields.
2420 (som_copy_private_backend_section_data): Always return a value.
2421
2422 * libhppa.h (PA_PAGESIZE): Define.
2423
2424 * som.c (SOM_ALIGN): Define.
2425 (som_begin_writing): If writing an executable, initialize all
2426 fields in the exec header to zero. Update fields in the exec
2427 header as sizes of loadable subspaces are computed. Carefully
2428 preserve alignments when building executables. Actually write the
2429 exec after all the fields are filled in.
2430
2431 * Better long-filename handling. Reads SOM ABI compliant extended
2432 names, but doesn't quite write compliant extended names yet.
2433 * som.c (som_slurp_extended_name_table): Delete function. The
2434 generic code will handle things correctly.
2435 (som_slurp_armap): Seek to the beginning of the next member.
2436 (normalize): New function.
2437 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2438 name table into account when computing the file offsets in the
2439 SOM dictionary. Make sure to align to an even boundary.
2440 (som_write_armap): Initialize the checksum to zero.
2441 (ar_maxchars): Fix. Opps.
2442
2443 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2444
2445 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2446 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2447
2448 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2449
2450 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2451 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2452 * bfd-in2.h: Regenerated.
2453
2454 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2455 this was also named trad_unix_bfd_copy_private_bfd_data.
2456
2457 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2458
2459 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2460 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2461 returns NULL, it is not an error. It's possible that some of
2462 these checks are not necessary (because the size can never be
2463 zero), but putting in the checks is the conservative thing to do
2464 in light of the fact that some of these malloc calls replaced
2465 unchecked alloca calls, in which a zero argument would work fine.
2466
2467 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2468
2469 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2470 duplicate definition.
2471 (osf_core_bfd_is_local_label): Define.
2472
2473 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2474 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2475 failure indication, it merely means there are no relocs.
2476
2477 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2478 after NAME, since SunOS /bin/cc can't handle it.
2479
2480 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2481
2482 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

2486
2487 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2488 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2489 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2490
2491 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2492
2493 * som.c (som_prep_for_fixups): Detect section symbols based
2494 on either the lack of private data or the symbol flags. Do not
2495 munge section symbol names anymore -- they no longer confuse GDB.
2496 (som_begin_writing): Leave space for an exec header if writing
2497 an executable.
2498 (som_slurp_symbol_table): Recognize both forms of section symbol
2499 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2500 section symbols to be the name of the section they represent.
2501 Debugging symbols begin with "L$0\001", not just "L$".
2502
2503 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2504
2505 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2506
2507 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2508 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2509 and bfd_is_local_label.
2510
2511 * targets.c: Add new entries to the bfd_target structure.
2512

2516
2517 * syms.c (bfd_is_local_label): New definition.
2518
2519 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2520
2521 * libbfd.c (bfd_generic_is_local_label): New function.
2522
2523 * *-core.c: Provide default definitions for new functions in
2524 the target vector which all point to bfd_false.
2525
2526 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2527 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2528 Default new vectors for copying private backend data to bfd_true.
2529 Default new vector for determining if a symbol is a local label
2530 to bfd_generic_is_local_label.
2531
2532 * som.c (som_bfd_copy_private_section_data): New function.
2533 (som_bfd_is_local_label): New function.
2534 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2535
2536 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2537
2538 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2539
2540 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2541
2542 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2543
2544 * Most files:
2545 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2546 Indent some of them to GNU standards.
2547
2548 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2549 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2550 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2551 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2552 Update copyright years.
2553
2554 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2555
2556 * som.c (som_prep_for_fixups): A relocation involving the section
2557 symbol for the *ABS* section is really a relocation involving
2558 no symbol.
2559 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2560 undefined symbols. Correctly distinguish between debugger symbols
2561 and section symbols.
2562
2563 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2564 for spaces and subspaces.
2565
2566 * som.c (som_bfd_count_ar_symbols): Fix typo.
2567
2568 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2569 HAS_RELOC based on the object's magic number.
2570 (make_unique_section): Delete function. BFD and its users are
2571 prepared to handle multiple sections with the same name.
2572 (setup_sections): Allocate space on the BFD's obstack to hold
2573 section names. Use bfd_make_setion_anyway rather than the
2574 obsolete make_unique_section.
2575 (som_prep_headers): Choose the correct SOM magic number based
2576 on the BFD's flags.
2577 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
2578
2579 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
2580
2581 * elf32-ppc.c: Renamed from elf32-powerpc.c.
2582 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
2583 * Makefile.in, configure.in: Corresponding changes.
2584
2585 Fri Mar 11 22:27:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2586
2587 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
2588
2589 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2590
2591 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
2592 is always located at the start of the data section to allow
2593 recovery of the dynamic info from a stripped executable.
2594 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
2595 and STYP_COMMENT.
2596
2597 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2598
2599 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
2600 cruft (like the #pragma alloca for AIX).
2601 In addition to that problem, the C alloca calls xmalloc, which
2602 means checking for being out of memory can't work right. The
2603 following changes remove all uses of alloca from BFD.
2604 * hosts/solaris2.h: Remove alloca cruft.
2605 * som.c: Replace alloca with a fixed size auto array.
2606 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
2607 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
2608 sunos.c: Replace alloca with malloc and appropriate error checking and
2609 freeing.
2610 * linker.c: Replace alloca with obstack_alloc.
2611 * libbfd.h: Rebuilt.
2612
2613 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
2614
2615 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
2616 MIPS_R_GPREL.
2617
2618 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2619
2620 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
2621 Elf*_Off typedefs by their expansion, the typedefs have been
2622 removed from include/elf/internal.h.
2623 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
2624 SHT_PROGBITS section.
2625
2626 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2627
2628 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
2629
2630 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2631
2632 * configure.host: Recognize i[34]86-sequent-*.
2633
2634 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
2635 return from bfd_seek indicates an error.
2636 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
2637 TRAD_CORE_STACK_OFFSET.
2638 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
2639 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
2640
2641 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2642
2643 * som.[ch]: Do not include libhppa.h in som.c, instead include
2644 it in som.h.
2645
2646 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
2647 include it in elf32-hppa.h.
2648
2649 * som.c (log2): Return -1 on error rather than aborting.
2650 (setup_sections): Bubble up an error from log2.
2651
2652 * Changes to make HP C compiler happy in both traditional
2653 and ANSI mode.
2654 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
2655 field parameter.
2656 (bfd_som_set_section_attributes): Use unsigned int rather than
2657 unsigned char to avoid GNU-C extensions.
2658 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
2659 or failure rather than aborting on failure.

2662 som.c changes.
2663 (bfd_som_attach_aux_hdr): Add prototype.

2666 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
2667 (hppa_look_for_stubs_in_section): Do not return false on failure
2668 until rest of code is ready to handle it. Abort for now.
2669
2670 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2671
2672 * bfd-in2.h: Rebuilt.
2673
2674 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
2675
2676 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
2677 * Makefile.in: delete an extra blank.
2678 * configure.in : Add i396os9k_vec.
2679
2680 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)
2681
2682 * config.bfd : Add i386-os9k.
2683 * config/i386-os9k.mt : Newly add os9k target makefile.

2691
2692 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
2693 action in case where caller specified no argument relocation.
2694 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
2695 right in the original relocation and the stub's relocation.
2696
2697 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
2698 unused symbols argument.
2699
2700 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
2701 than asymbol * for original target symbol. All callers changed.
2702 Set reloc->sym_ptr_ptr appropriately.
2703 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
2704 (hppa_elf_look_for_stubs_in_section): No longer need symbols
2705 argument. Use the output symbols when canonicalizing the relocs,
2706 creating them if necessary.
2707
2708 * linker.c (_bfd_generic_link_output_symbols): Do not
2709 rebuild/clobber the output symbols if they already exist.
2710
2711 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)

2721
2722 * elf32-hppa.c: Second half of major cleanup. More comments,
2723 PARAMize and staticize rest of functions. Delete unused
2724 functions. Delete unused/unnecessary arguments to some functions.
2725 Group static vars together. Abort for bad errors until we have
2726 error code propogation working. Work on spacing and indention.
2727 Add FIXMEs for unresolved problems. Use enums rather than
2728 #defines for lots of things. Merge two functions which build
2729 linker stubs into a single function (so they can easily share a
2730 ton of common code).
2731
2732 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
2733
2734 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
2735 avoid depending upon right shifts of signed numbers, and to
2736 correct handling of src_mask with lower bits zero.

2739 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
2740 * elf32-i386.c: Likewise.
2741 * elfcode.h (bfd_section_from_shdr): Make i unsigned; remove old
2742 #if 0 code.
2743 (elf_write_phdrs): Make i unsigned.
2744 (map_program_segments): Make i and n_left unsigned.

2754 (swap_out_syms): Use BFD_ASSERT rather than assert.
2755
2756 * linker.c (_bfd_generic_link_write_global_symbol): Add missing
2757 break in switch.

2771 comments. PARAMize some static functions. Delete unused functions.
2772 Delete unused/unnecessary arguments to many functions. Group
2773 static vars together. Collapse common case statements together
2774 in many places. Use default case when possible instead of listing
2775 each case separately. Abort for bad errors until we get error
2776 code propogation working. Work on spacing and indention problems.
2777 Add FIXMEs for some unresolved problems. Delete hopelessly broken
2778 COMPLEX relocation support (it's never used anyway).
2779 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
2780 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
2781 (elf_hppa_tc_make_sections): Likewise.
2782
2783 * format.c (bfd_check_format_matches): Initialize matching_vector
2784 to keep gcc -Wall quiet.
2785
2786 * elfcode.h (elf_slurp_reloca_table): Fix typo.
2787
2788 * som.c (som_get_symtab_upper_bound): Use "sizeof (asymbol *)"
2789 not "sizeof (som_symbol_type *)".

3486
3487 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros

3704 return value.
3705 * aoutf1.h (NAME(aout,sunos4_write_object_contents)): Don't write
3706 out dynamic symbols or relocs against reloc symbols, since they
3707 are already in the .text section and we wouldn't know where to
3708 write them anyhow.
