456 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
458 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
459 bfd_zalloc for rawptr, because later on we may call free, not
462 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
463 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
464 * cisco-core.c: New file.
465 * Makefile.in: Change accordingly.
466 * configure.in: Recognize cisco_core_vec.
467 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
468 * targets.c: Add cisco_core_vec.
469 * bfd-in2.h: Rebuilt.
471 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
473 * som.h (som_copyable_section_data_struct): New structure
474 containing all the private section information which needs
475 to be copied from input section to output section during
477 (som_section_data_struct): Remove several fields now in
478 som_copyable_section_data_struct. Make the space and
479 subspace dictionaries be pointers (to save space when
480 only reading objects).
482 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
483 some references changed. Allocate a copyable data stucture if
484 none exists. Store info into the copyable data structure.
485 (bfd_som_set_subsection_attributes): Likewise.
486 (som_is_space, som_is_subspace, som_is_container): New functions.
487 Use these instead of directly accessing private data.
488 (som_prep_headers): Allocate space and subspace headers here.
489 Fill in some fields in the space/subspace headers from the
491 (som_bfd_copy_private_section_data): Only copy the stuff
492 that we really need to make objcopy and strip work. Allocate
493 the copy_data structure for the output bfd before copying.
495 * som.h (struct som_exec_data): New structure to hold exec
496 info that must be preserved when running objcopy/strip.
497 (struct somdata): Add new "exec_data" field and accessor
498 macro. Add some comments on how the various fields are used.
499 (som_section_data_struct): Make is_space and is_subspace bitfields.
500 Delete unused subspace_index. All references now use the
501 target_index field within the section structure itself.
503 * som.c (make_unique_section): Delete unused declaration.
504 (som_bfd_copy_private_bfd_data): New function.
505 (som_object_setup): Allocate space for and save exec information
506 that needs to be copied during objcopy/strip.
507 (som_mkobject): Do not allocate space for a file header here.
508 It is not used when only reading SOM objects.
509 (som_prep_headers): Allocate space for and attach a file header
510 to the output bfd. For executables, use the saved system_id
511 value rather than trying to guess the right value. Do not abort
512 wwhen setting file_hdr->entry* for executables.
513 (som_begin_writing): For executables, set the exec_entry and
515 (som_copy_private_backend_section_data): Always return a value.
517 * libhppa.h (PA_PAGESIZE): Define.
519 * som.c (SOM_ALIGN): Define.
520 (som_begin_writing): If writing an executable, initialize all
521 fields in the exec header to zero. Update fields in the exec
522 header as sizes of loadable subspaces are computed. Carefully
523 preserve alignments when building executables. Actually write the
524 exec after all the fields are filled in.
526 * Better long-filename handling. Reads SOM ABI compliant extended
527 names, but doesn't quite write compliant extended names yet.
528 * som.c (som_slurp_extended_name_table): Delete function. The
529 generic code will handle things correctly.
530 (som_slurp_armap): Seek to the beginning of the next member.
531 (normalize): New function.
532 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
533 name table into account when computing the file offsets in the
534 SOM dictionary. Make sure to align to an even boundary.
535 (som_write_armap): Initialize the checksum to zero.
536 (ar_maxchars): Fix. Opps.
538 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
540 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
541 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

545 * bfd-in.h (BFD_VERSION): Use @VERSION@.
546 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
547 * bfd-in2.h: Regenerated.
549 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
550 this was also named trad_unix_bfd_copy_private_bfd_data.
552 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
554 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
555 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
556 returns NULL, it is not an error. It's possible that some of
557 these checks are not necessary (because the size can never be
558 zero), but putting in the checks is the conservative thing to do
559 in light of the fact that some of these malloc calls replaced
560 unchecked alloca calls, in which a zero argument would work fine.
562 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
564 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
565 duplicate definition.
566 (osf_core_bfd_is_local_label): Define.
568 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
569 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
570 failure indication, it merely means there are no relocs.
572 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
573 after NAME, since SunOS /bin/cc can't handle it.
575 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
577 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
578 From sukes@glue.umd.edu (Tasuki Hirata).
580 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
582 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
583 all that convoluted stuff with NAME, CAT3, etc. The convoluted
584 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
586 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
588 * som.c (som_prep_for_fixups): Detect section symbols based
589 on either the lack of private data or the symbol flags. Do not
590 munge section symbol names anymore -- they no longer confuse GDB.
591 (som_begin_writing): Leave space for an exec header if writing
593 (som_slurp_symbol_table): Recognize both forms of section symbol
594 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
595 section symbols to be the name of the section they represent.
596 Debugging symbols begin with "L$0\001", not just "L$".

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

664 HAS_RELOC based on the object's magic number.
665 (make_unique_section): Delete function. BFD and its users are
666 prepared to handle multiple sections with the same name.
667 (setup_sections): Allocate space on the BFD's obstack to hold
668 section names. Use bfd_make_setion_anyway rather than the
669 obsolete make_unique_section.
670 (som_prep_headers): Choose the correct SOM magic number based
672 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
674 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)

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

717 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
718 Elf*_Off typedefs by their expansion, the typedefs have been
719 removed from include/elf/internal.h.
720 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
721 SHT_PROGBITS section.

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

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

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

870 static vars together. Collapse common case statements together
871 in many places. Use default case when possible instead of listing
872 each case separately. Abort for bad errors until we get error
873 code propogation working. Work on spacing and indention problems.
874 Add FIXMEs for some unresolved problems. Delete hopelessly broken
875 COMPLEX relocation support (it's never used anyway).
876 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.

1728 use get_value to get the symbol value and check for undefined
1730 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
1731 undefined, look it up in the linker hash table.
1733 * aoutx.h (translate_symbol_table): The string index 0 has a

1758 The sparc (and possibly other?) NLM format requires a different
1759 way to write exports, so add a write_export field to the backend
1760 data (and set it to NULL for everything but the sparc).
