451 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
454 * som.c (som_begin_writing): Fix braino (one call to align
455 space/subspace data was done unconditionally rather than
456 just for executables.)
458 * som.c (som_begin_writing): Align text in all executables to
459 make HPUX kernel happy. Fixes strip/objcopy for shared
462 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
464 * som.c (som_begin_writing): Account for alignment needs of
465 subspaces too when writing executables. Never request a negative
466 bss size. Fixes some problems with demand paged executables,
467 still having problems with pure executables and shared executables.
469 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
471 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
472 bfd_zalloc for rawptr, because later on we may call free, not
475 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
476 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
477 * cisco-core.c: New file.
478 * Makefile.in: Change accordingly.
479 * configure.in: Recognize cisco_core_vec.
480 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
481 * targets.c: Add cisco_core_vec.
482 * bfd-in2.h: Rebuilt.
484 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
486 * som.h (som_copyable_section_data_struct): New structure
487 containing all the private section information which needs
488 to be copied from input section to output section during
490 (som_section_data_struct): Remove several fields now in
491 som_copyable_section_data_struct. Make the space and
492 subspace dictionaries be pointers (to save space when
493 only reading objects).
495 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
496 some references changed. Allocate a copyable data stucture if
497 none exists. Store info into the copyable data structure.
498 (bfd_som_set_subsection_attributes): Likewise.
499 (som_is_space, som_is_subspace, som_is_container): New functions.
500 Use these instead of directly accessing private data.
501 (som_prep_headers): Allocate space and subspace headers here.
502 Fill in some fields in the space/subspace headers from the
504 (som_bfd_copy_private_section_data): Only copy the stuff
505 that we really need to make objcopy and strip work. Allocate
506 the copy_data structure for the output bfd before copying.
508 * som.h (struct som_exec_data): New structure to hold exec
509 info that must be preserved when running objcopy/strip.
510 (struct somdata): Add new "exec_data" field and accessor
511 macro. Add some comments on how the various fields are used.
512 (som_section_data_struct): Make is_space and is_subspace bitfields.
513 Delete unused subspace_index. All references now use the
514 target_index field within the section structure itself.
516 * som.c (make_unique_section): Delete unused declaration.
517 (som_bfd_copy_private_bfd_data): New function.
518 (som_object_setup): Allocate space for and save exec information
519 that needs to be copied during objcopy/strip.
520 (som_mkobject): Do not allocate space for a file header here.
521 It is not used when only reading SOM objects.
522 (som_prep_headers): Allocate space for and attach a file header
523 to the output bfd. For executables, use the saved system_id
524 value rather than trying to guess the right value. Do not abort
525 wwhen setting file_hdr->entry* for executables.
526 (som_begin_writing): For executables, set the exec_entry and
528 (som_copy_private_backend_section_data): Always return a value.
530 * libhppa.h (PA_PAGESIZE): Define.
532 * som.c (SOM_ALIGN): Define.
533 (som_begin_writing): If writing an executable, initialize all
534 fields in the exec header to zero. Update fields in the exec
535 header as sizes of loadable subspaces are computed. Carefully
536 preserve alignments when building executables. Actually write the
537 exec after all the fields are filled in.
539 * Better long-filename handling. Reads SOM ABI compliant extended
540 names, but doesn't quite write compliant extended names yet.
541 * som.c (som_slurp_extended_name_table): Delete function. The
542 generic code will handle things correctly.
543 (som_slurp_armap): Seek to the beginning of the next member.
544 (normalize): New function.
545 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
546 name table into account when computing the file offsets in the
547 SOM dictionary. Make sure to align to an even boundary.
548 (som_write_armap): Initialize the checksum to zero.
549 (ar_maxchars): Fix. Opps.
551 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
553 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
554 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
556 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
558 * bfd-in.h (BFD_VERSION): Use @VERSION@.
559 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
560 * bfd-in2.h: Regenerated.
562 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
563 this was also named trad_unix_bfd_copy_private_bfd_data.
565 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
567 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
568 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
569 returns NULL, it is not an error. It's possible that some of
570 these checks are not necessary (because the size can never be
571 zero), but putting in the checks is the conservative thing to do
572 in light of the fact that some of these malloc calls replaced
573 unchecked alloca calls, in which a zero argument would work fine.
575 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
577 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
578 duplicate definition.
579 (osf_core_bfd_is_local_label): Define.
581 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
582 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
583 failure indication, it merely means there are no relocs.
585 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
586 after NAME, since SunOS /bin/cc can't handle it.
588 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
590 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
591 From sukes@glue.umd.edu (Tasuki Hirata).
593 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
595 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
596 all that convoluted stuff with NAME, CAT3, etc. The convoluted
597 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
599 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
601 * som.c (som_prep_for_fixups): Detect section symbols based
602 on either the lack of private data or the symbol flags. Do not
603 munge section symbol names anymore -- they no longer confuse GDB.
604 (som_begin_writing): Leave space for an exec header if writing
606 (som_slurp_symbol_table): Recognize both forms of section symbol
607 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
608 section symbols to be the name of the section they represent.
609 Debugging symbols begin with "L$0\001", not just "L$".
611 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
613 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
615 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
616 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
617 and bfd_is_local_label.
619 * targets.c: Add new entries to the bfd_target structure.
621 * bfd.c (bfd_copy_private_bfd_data): New definition.
623 * section.c (bfd_copy_private_section_data): New definition.

627 * libbfd-in.h (bfd_generic_is_local_label): Declare.
629 * libbfd.c (bfd_generic_is_local_label): New function.
631 * *-core.c: Provide default definitions for new functions in
632 the target vector which all point to bfd_false.
634 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
635 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
636 Default new vectors for copying private backend data to bfd_true.
637 Default new vector for determining if a symbol is a local label
638 to bfd_generic_is_local_label.
640 * som.c (som_bfd_copy_private_section_data): New function.
641 (som_bfd_is_local_label): New function.
642 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
644 * elf32-hppa.c (hppa_elf_is_local_label): New function.
646 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
648 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
650 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
653 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
654 Indent some of them to GNU standards.
656 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
657 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
658 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
659 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
660 Update copyright years.
662 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
664 * som.c (som_prep_for_fixups): A relocation involving the section
665 symbol for the *ABS* section is really a relocation involving
667 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
668 undefined symbols. Correctly distinguish between debugger symbols
671 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
672 for spaces and subspaces.
674 * som.c (som_bfd_count_ar_symbols): Fix typo.
676 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
677 HAS_RELOC based on the object's magic number.
678 (make_unique_section): Delete function. BFD and its users are
679 prepared to handle multiple sections with the same name.
680 (setup_sections): Allocate space on the BFD's obstack to hold
681 section names. Use bfd_make_setion_anyway rather than the
682 obsolete make_unique_section.
683 (som_prep_headers): Choose the correct SOM magic number based
685 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
687 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
689 * elf32-ppc.c: Renamed from elf32-powerpc.c.

707 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
709 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
710 cruft (like the #pragma alloca for AIX).
711 In addition to that problem, the C alloca calls xmalloc, which
712 means checking for being out of memory can't work right. The
713 following changes remove all uses of alloca from BFD.
714 * hosts/solaris2.h: Remove alloca cruft.
715 * som.c: Replace alloca with a fixed size auto array.
716 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,

730 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
731 Elf*_Off typedefs by their expansion, the typedefs have been
732 removed from include/elf/internal.h.
733 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
734 SHT_PROGBITS section.

744 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
745 return from bfd_seek indicates an error.
746 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
747 TRAD_CORE_STACK_OFFSET.
748 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
749 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
751 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
753 * som.[ch]: Do not include libhppa.h in som.c, instead include
756 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
757 include it in elf32-hppa.h.
759 * som.c (log2): Return -1 on error rather than aborting.
760 (setup_sections): Bubble up an error from log2.
762 * Changes to make HP C compiler happy in both traditional
764 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
766 (bfd_som_set_section_attributes): Use unsigned int rather than
767 unsigned char to avoid GNU-C extensions.
768 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
769 or failure rather than aborting on failure.
771 * som.h (bfd_som_set_section_attributes): Fix prototype to match
773 (bfd_som_attach_aux_hdr): Add prototype.
774 (hppa_som-gen_reloc_type): Likewise.

813 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
814 (hppa_elf_look_for_stubs_in_section): No longer need symbols
815 argument. Use the output symbols when canonicalizing the relocs,
816 creating them if necessary.
818 * linker.c (_bfd_generic_link_output_symbols): Do not
819 rebuild/clobber the output symbols if they already exist.
821 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
823 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
824 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
825 * bfd-in2.h: Rebuilt.
827 * srec.c (hex_value): Always set to a size of 256 bytes.
828 (srec_init): Cosmetic changes.
830 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
832 * elf32-hppa.c: Second half of major cleanup. More comments,
833 PARAMize and staticize rest of functions. Delete unused
834 functions. Delete unused/unnecessary arguments to some functions.
835 Group static vars together. Abort for bad errors until we have
836 error code propogation working. Work on spacing and indention.
837 Add FIXMEs for unresolved problems. Use enums rather than
838 #defines for lots of things. Merge two functions which build
839 linker stubs into a single function (so they can easily share a
842 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
844 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to

882 Delete unused/unnecessary arguments to many functions. Group
883 static vars together. Collapse common case statements together
884 in many places. Use default case when possible instead of listing
885 each case separately. Abort for bad errors until we get error
886 code propogation working. Work on spacing and indention problems.
887 Add FIXMEs for some unresolved problems. Delete hopelessly broken
888 COMPLEX relocation support (it's never used anyway).
889 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
890 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
891 (elf_hppa_tc_make_sections): Likewise.

1741 use get_value to get the symbol value and check for undefined
1743 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
1744 undefined, look it up in the linker hash table.
1746 * aoutx.h (translate_symbol_table): The string index 0 has a

1771 The sparc (and possibly other?) NLM format requires a different
1772 way to write exports, so add a write_export field to the backend
1773 data (and set it to NULL for everything but the sparc).
