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

613 * *-core.c: Provide default definitions for new functions in
614 the target vector which all point to bfd_false.
616 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
617 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
618 Default new vectors for copying private backend data to bfd_true.
619 Default new vector for determining if a symbol is a local label
620 to bfd_generic_is_local_label.
622 * som.c (som_bfd_copy_private_section_data): New function.
623 (som_bfd_is_local_label): New function.
624 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
626 * elf32-hppa.c (hppa_elf_is_local_label): New function.
628 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
630 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
632 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
635 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
636 Indent some of them to GNU standards.
638 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
639 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
640 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
641 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
642 Update copyright years.
644 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
646 * som.c (som_prep_for_fixups): A relocation involving the section
647 symbol for the *ABS* section is really a relocation involving
649 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
650 undefined symbols. Correctly distinguish between debugger symbols
653 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
654 for spaces and subspaces.
656 * som.c (som_bfd_count_ar_symbols): Fix typo.

659 HAS_RELOC based on the object's magic number.
660 (make_unique_section): Delete function. BFD and its users are
661 prepared to handle multiple sections with the same name.
662 (setup_sections): Allocate space on the BFD's obstack to hold
663 section names. Use bfd_make_setion_anyway rather than the
664 obsolete make_unique_section.
665 (som_prep_headers): Choose the correct SOM magic number based
667 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
669 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
671 * elf32-ppc.c: Renamed from elf32-powerpc.c.

689 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
691 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
692 cruft (like the #pragma alloca for AIX).
693 In addition to that problem, the C alloca calls xmalloc, which
694 means checking for being out of memory can't work right. The
695 following changes remove all uses of alloca from BFD.
696 * hosts/solaris2.h: Remove alloca cruft.
697 * som.c: Replace alloca with a fixed size auto array.

712 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
713 Elf*_Off typedefs by their expansion, the typedefs have been
714 removed from include/elf/internal.h.
715 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
716 SHT_PROGBITS section.

726 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
727 return from bfd_seek indicates an error.
728 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
729 TRAD_CORE_STACK_OFFSET.
730 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
731 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
733 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
735 * som.[ch]: Do not include libhppa.h in som.c, instead include
738 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
739 include it in elf32-hppa.h.

742 (setup_sections): Bubble up an error from log2.
744 * Changes to make HP C compiler happy in both traditional
746 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
748 (bfd_som_set_section_attributes): Use unsigned int rather than
749 unsigned char to avoid GNU-C extensions.
750 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
751 or failure rather than aborting on failure.
753 * som.h (bfd_som_set_section_attributes): Fix prototype to match
755 (bfd_som_attach_aux_hdr): Add prototype.
756 (hppa_som-gen_reloc_type): Likewise.

815 PARAMize and staticize rest of functions. Delete unused
816 functions. Delete unused/unnecessary arguments to some functions.
817 Group static vars together. Abort for bad errors until we have
818 error code propogation working. Work on spacing and indention.
819 Add FIXMEs for unresolved problems. Use enums rather than
820 #defines for lots of things. Merge two functions which build
821 linker stubs into a single function (so they can easily share a

864 Delete unused/unnecessary arguments to many functions. Group
865 static vars together. Collapse common case statements together
866 in many places. Use default case when possible instead of listing
867 each case separately. Abort for bad errors until we get error
868 code propogation working. Work on spacing and indention problems.
869 Add FIXMEs for some unresolved problems. Delete hopelessly broken
870 COMPLEX relocation support (it's never used anyway).
871 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
872 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).

1615 bfd_som_set_subsection_attributes): Change parameters from char
1616 to int. Following a prototype with an old-style function definition

1723 use get_value to get the symbol value and check for undefined
1725 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
1726 undefined, look it up in the linker hash table.
1728 * aoutx.h (translate_symbol_table): The string index 0 has a

1753 The sparc (and possibly other?) NLM format requires a different
1754 way to write exports, so add a write_export field to the backend
1755 data (and set it to NULL for everything but the sparc).

1805 read_dynamic_relocs fields.
1806 * aout-target.h (MY(backend_data)): Initialize
