452 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
454 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
456 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
458 * som.c (bfd_section_from_som_symbol): Only to do the value
459 comparison for function symbols within executables.
461 * som.c (bfd_section_from_som_symbol): Renamed from
462 som_section_from_subspace_index. Pass in a native SOM symbol.
463 For executables, iterate through the sections to find out
464 which contains the symbol's address rather than using the
465 symbol_info field. (symbol_info has a different meaning for
466 dynamicly linked executables.)
468 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
471 * som.c (som_begin_writing): Fix braino (one call to align
472 space/subspace data was done unconditionally rather than
473 just for executables.)
475 * som.c (som_begin_writing): Align text in all executables to
476 make HPUX kernel happy. Fixes strip/objcopy for shared
479 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
481 * som.c (som_begin_writing): Account for alignment needs of
482 subspaces too when writing executables. Never request a negative
483 bss size. Fixes some problems with demand paged executables,
484 still having problems with pure executables and shared executables.
486 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
488 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
489 bfd_zalloc for rawptr, because later on we may call free, not
492 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
493 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
494 * cisco-core.c: New file.
495 * Makefile.in: Change accordingly.
496 * configure.in: Recognize cisco_core_vec.
497 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
498 * targets.c: Add cisco_core_vec.
499 * bfd-in2.h: Rebuilt.
501 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
503 * som.h (som_copyable_section_data_struct): New structure
504 containing all the private section information which needs
505 to be copied from input section to output section during
507 (som_section_data_struct): Remove several fields now in
508 som_copyable_section_data_struct. Make the space and
509 subspace dictionaries be pointers (to save space when
510 only reading objects).
512 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
513 some references changed. Allocate a copyable data stucture if
514 none exists. Store info into the copyable data structure.
515 (bfd_som_set_subsection_attributes): Likewise.
516 (som_is_space, som_is_subspace, som_is_container): New functions.
517 Use these instead of directly accessing private data.
518 (som_prep_headers): Allocate space and subspace headers here.
519 Fill in some fields in the space/subspace headers from the
521 (som_bfd_copy_private_section_data): Only copy the stuff
522 that we really need to make objcopy and strip work. Allocate
523 the copy_data structure for the output bfd before copying.
525 * som.h (struct som_exec_data): New structure to hold exec
526 info that must be preserved when running objcopy/strip.
527 (struct somdata): Add new "exec_data" field and accessor
528 macro. Add some comments on how the various fields are used.
529 (som_section_data_struct): Make is_space and is_subspace bitfields.
530 Delete unused subspace_index. All references now use the
531 target_index field within the section structure itself.
533 * som.c (make_unique_section): Delete unused declaration.
534 (som_bfd_copy_private_bfd_data): New function.
535 (som_object_setup): Allocate space for and save exec information
536 that needs to be copied during objcopy/strip.
537 (som_mkobject): Do not allocate space for a file header here.
538 It is not used when only reading SOM objects.
539 (som_prep_headers): Allocate space for and attach a file header
540 to the output bfd. For executables, use the saved system_id
541 value rather than trying to guess the right value. Do not abort
542 wwhen setting file_hdr->entry* for executables.
543 (som_begin_writing): For executables, set the exec_entry and
545 (som_copy_private_backend_section_data): Always return a value.
547 * libhppa.h (PA_PAGESIZE): Define.
549 * som.c (SOM_ALIGN): Define.
550 (som_begin_writing): If writing an executable, initialize all
551 fields in the exec header to zero. Update fields in the exec
552 header as sizes of loadable subspaces are computed. Carefully
553 preserve alignments when building executables. Actually write the
554 exec after all the fields are filled in.
556 * Better long-filename handling. Reads SOM ABI compliant extended
557 names, but doesn't quite write compliant extended names yet.
558 * som.c (som_slurp_extended_name_table): Delete function. The
559 generic code will handle things correctly.
560 (som_slurp_armap): Seek to the beginning of the next member.
561 (normalize): New function.
562 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
563 name table into account when computing the file offsets in the
564 SOM dictionary. Make sure to align to an even boundary.
565 (som_write_armap): Initialize the checksum to zero.
566 (ar_maxchars): Fix. Opps.
568 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
570 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
571 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
573 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
575 * bfd-in.h (BFD_VERSION): Use @VERSION@.
576 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
577 * bfd-in2.h: Regenerated.
579 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
580 this was also named trad_unix_bfd_copy_private_bfd_data.
582 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
584 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
585 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
586 returns NULL, it is not an error. It's possible that some of
587 these checks are not necessary (because the size can never be
588 zero), but putting in the checks is the conservative thing to do
589 in light of the fact that some of these malloc calls replaced
590 unchecked alloca calls, in which a zero argument would work fine.
592 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
594 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
595 duplicate definition.
596 (osf_core_bfd_is_local_label): Define.
598 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
599 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
600 failure indication, it merely means there are no relocs.
602 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
603 after NAME, since SunOS /bin/cc can't handle it.
605 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
607 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
608 From sukes@glue.umd.edu (Tasuki Hirata).
610 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
612 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
613 all that convoluted stuff with NAME, CAT3, etc. The convoluted
614 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
616 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
618 * som.c (som_prep_for_fixups): Detect section symbols based
619 on either the lack of private data or the symbol flags. Do not
620 munge section symbol names anymore -- they no longer confuse GDB.
621 (som_begin_writing): Leave space for an exec header if writing
623 (som_slurp_symbol_table): Recognize both forms of section symbol
624 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
625 section symbols to be the name of the section they represent.
626 Debugging symbols begin with "L$0\001", not just "L$".
628 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
630 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
632 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
633 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
634 and bfd_is_local_label.
636 * targets.c: Add new entries to the bfd_target structure.
638 * bfd.c (bfd_copy_private_bfd_data): New definition.
640 * section.c (bfd_copy_private_section_data): New definition.
642 * syms.c (bfd_is_local_label): New definition.
644 * libbfd-in.h (bfd_generic_is_local_label): Declare.
646 * libbfd.c (bfd_generic_is_local_label): New function.
648 * *-core.c: Provide default definitions for new functions in
649 the target vector which all point to bfd_false.
651 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
652 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
653 Default new vectors for copying private backend data to bfd_true.
654 Default new vector for determining if a symbol is a local label
655 to bfd_generic_is_local_label.
657 * som.c (som_bfd_copy_private_section_data): New function.
658 (som_bfd_is_local_label): New function.
659 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
661 * elf32-hppa.c (hppa_elf_is_local_label): New function.
663 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
665 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
667 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
670 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
671 Indent some of them to GNU standards.
673 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
674 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
675 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
676 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
677 Update copyright years.
679 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
681 * som.c (som_prep_for_fixups): A relocation involving the section
682 symbol for the *ABS* section is really a relocation involving
684 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
685 undefined symbols. Correctly distinguish between debugger symbols
688 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
689 for spaces and subspaces.
691 * som.c (som_bfd_count_ar_symbols): Fix typo.
693 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
694 HAS_RELOC based on the object's magic number.
695 (make_unique_section): Delete function. BFD and its users are
696 prepared to handle multiple sections with the same name.
697 (setup_sections): Allocate space on the BFD's obstack to hold
698 section names. Use bfd_make_setion_anyway rather than the
699 obsolete make_unique_section.
700 (som_prep_headers): Choose the correct SOM magic number based
702 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
704 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
706 * elf32-ppc.c: Renamed from elf32-powerpc.c.

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

747 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
748 Elf*_Off typedefs by their expansion, the typedefs have been
749 removed from include/elf/internal.h.
750 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
751 SHT_PROGBITS section.
753 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
755 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
757 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
759 * configure.host: Recognize i[34]86-sequent-*.
761 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
762 return from bfd_seek indicates an error.
763 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
764 TRAD_CORE_STACK_OFFSET.
765 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
766 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
768 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
770 * som.[ch]: Do not include libhppa.h in som.c, instead include
773 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
774 include it in elf32-hppa.h.
776 * som.c (log2): Return -1 on error rather than aborting.
777 (setup_sections): Bubble up an error from log2.
779 * Changes to make HP C compiler happy in both traditional
781 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
783 (bfd_som_set_section_attributes): Use unsigned int rather than
784 unsigned char to avoid GNU-C extensions.
785 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
786 or failure rather than aborting on failure.
788 * som.h (bfd_som_set_section_attributes): Fix prototype to match
790 (bfd_som_attach_aux_hdr): Add prototype.
791 (hppa_som-gen_reloc_type): Likewise.

797 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
799 * bfd-in2.h: Rebuilt.
801 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

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

829 Set reloc->sym_ptr_ptr appropriately.
830 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
831 (hppa_elf_look_for_stubs_in_section): No longer need symbols
832 argument. Use the output symbols when canonicalizing the relocs,
833 creating them if necessary.
835 * linker.c (_bfd_generic_link_output_symbols): Do not
836 rebuild/clobber the output symbols if they already exist.
838 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
840 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
841 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
842 * bfd-in2.h: Rebuilt.
844 * srec.c (hex_value): Always set to a size of 256 bytes.
845 (srec_init): Cosmetic changes.
847 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
849 * elf32-hppa.c: Second half of major cleanup. More comments,
850 PARAMize and staticize rest of functions. Delete unused
851 functions. Delete unused/unnecessary arguments to some functions.
852 Group static vars together. Abort for bad errors until we have
853 error code propogation working. Work on spacing and indention.
854 Add FIXMEs for unresolved problems. Use enums rather than
855 #defines for lots of things. Merge two functions which build
856 linker stubs into a single function (so they can easily share a
859 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
861 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
862 avoid depending upon right shifts of signed numbers, and to
863 correct handling of src_mask with lower bits zero.

898 comments. PARAMize some static functions. Delete unused functions.
899 Delete unused/unnecessary arguments to many functions. Group
900 static vars together. Collapse common case statements together
901 in many places. Use default case when possible instead of listing
902 each case separately. Abort for bad errors until we get error
903 code propogation working. Work on spacing and indention problems.
904 Add FIXMEs for some unresolved problems. Delete hopelessly broken
905 COMPLEX relocation support (it's never used anyway).
906 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
907 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
908 (elf_hppa_tc_make_sections): Likewise.
910 * format.c (bfd_check_format_matches): Initialize matching_vector
911 to keep gcc -Wall quiet.
913 * elfcode.h (elf_slurp_reloca_table): Fix typo.

1758 use get_value to get the symbol value and check for undefined
1760 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
1761 undefined, look it up in the linker hash table.
1763 * aoutx.h (translate_symbol_table): The string index 0 has a

1788 The sparc (and possibly other?) NLM format requires a different
1789 way to write exports, so add a write_export field to the backend
1790 data (and set it to NULL for everything but the sparc).
