444 Tue Mar 22 10:04:00 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
446 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
447 for first character in an extended name.
448 (_bfd_write_archive_contents): If ar_padchar == '/', then use
449 "//" as the name of the special archive member holding the
452 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
454 Support for link_order types which generate relocs in order to
455 support -Ur in the linker.
456 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
457 from call to _bfd_generic_link_add_one_symbol.
458 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
459 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
460 instead of bitsize to add_to_set call back.
461 (_bfd_generic_final_link): Account for link_order relocs when
462 allocating space for relocations. Handle them in link_order loop.
463 (_bfd_generic_reloc_link_order): New function.
464 (_bfd_default_link_order): If a reloc_link_order is seen here,
466 (_bfd_count_link_order_relocs): New function.
467 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
468 argument from declaration.
469 (_bfd_generic_reloc_link_order): Declare.
470 (_bfd_count_link_order_relocs): Declare.
472 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
473 call to _bfd_generic_link_add_one_symbol.
474 (NAME(aout,final_link)): Account for link_order relocs when
475 allocating space for relocations. Handle them after handling all
477 (aout_link_reloc_link_order): New function.
478 * ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
479 call to _bfd_generic_link_add_one_symbol.
480 (ecoff_bfd_final_link): Account for link_order relocs when
481 allocating space for relocations. Handle them in link_order loop.
482 (ecoff_link_write_external): Set the storage class of a defined
483 linker created symbol based on the section it is in. Correct
484 bfd_link_hash_weak case to use .sc rather than .st.
485 (ecoff_reloc_link_order): New function.
486 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
488 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
490 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
493 * cisco-core.c (cisco_core_file_p): Only pass one argument to
494 bfd_zmalloc. Free a pointer, not a union.
495 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
497 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
499 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
501 * som.c (bfd_section_from_som_symbol): Only to do the value
502 comparison for function symbols within executables.
504 * som.c (bfd_section_from_som_symbol): Renamed from
505 som_section_from_subspace_index. Pass in a native SOM symbol.
506 For executables, iterate through the sections to find out
507 which contains the symbol's address rather than using the
508 symbol_info field. (symbol_info has a different meaning for
509 dynamicly linked executables.)
511 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
514 * som.c (som_begin_writing): Fix braino (one call to align
515 space/subspace data was done unconditionally rather than
516 just for executables.)
518 * som.c (som_begin_writing): Align text in all executables to
519 make HPUX kernel happy. Fixes strip/objcopy for shared
522 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
524 * som.c (som_begin_writing): Account for alignment needs of
525 subspaces too when writing executables. Never request a negative
526 bss size. Fixes some problems with demand paged executables,
527 still having problems with pure executables and shared executables.
529 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
531 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
532 bfd_zalloc for rawptr, because later on we may call free, not
535 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
536 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
537 * cisco-core.c: New file.
538 * Makefile.in: Change accordingly.
539 * configure.in: Recognize cisco_core_vec.
540 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
541 * targets.c: Add cisco_core_vec.
542 * bfd-in2.h: Rebuilt.
544 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
546 * som.h (som_copyable_section_data_struct): New structure
547 containing all the private section information which needs
548 to be copied from input section to output section during
550 (som_section_data_struct): Remove several fields now in
551 som_copyable_section_data_struct. Make the space and
552 subspace dictionaries be pointers (to save space when
553 only reading objects).
555 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
556 some references changed. Allocate a copyable data stucture if
557 none exists. Store info into the copyable data structure.
558 (bfd_som_set_subsection_attributes): Likewise.
559 (som_is_space, som_is_subspace, som_is_container): New functions.
560 Use these instead of directly accessing private data.
561 (som_prep_headers): Allocate space and subspace headers here.
562 Fill in some fields in the space/subspace headers from the
564 (som_bfd_copy_private_section_data): Only copy the stuff
565 that we really need to make objcopy and strip work. Allocate
566 the copy_data structure for the output bfd before copying.
568 * som.h (struct som_exec_data): New structure to hold exec
569 info that must be preserved when running objcopy/strip.
570 (struct somdata): Add new "exec_data" field and accessor
571 macro. Add some comments on how the various fields are used.
572 (som_section_data_struct): Make is_space and is_subspace bitfields.
573 Delete unused subspace_index. All references now use the
574 target_index field within the section structure itself.
576 * som.c (make_unique_section): Delete unused declaration.
577 (som_bfd_copy_private_bfd_data): New function.
578 (som_object_setup): Allocate space for and save exec information
579 that needs to be copied during objcopy/strip.
580 (som_mkobject): Do not allocate space for a file header here.
581 It is not used when only reading SOM objects.
582 (som_prep_headers): Allocate space for and attach a file header
583 to the output bfd. For executables, use the saved system_id
584 value rather than trying to guess the right value. Do not abort
585 wwhen setting file_hdr->entry* for executables.
586 (som_begin_writing): For executables, set the exec_entry and
588 (som_copy_private_backend_section_data): Always return a value.
590 * libhppa.h (PA_PAGESIZE): Define.
592 * som.c (SOM_ALIGN): Define.
593 (som_begin_writing): If writing an executable, initialize all
594 fields in the exec header to zero. Update fields in the exec
595 header as sizes of loadable subspaces are computed. Carefully
596 preserve alignments when building executables. Actually write the
597 exec after all the fields are filled in.
599 * Better long-filename handling. Reads SOM ABI compliant extended
600 names, but doesn't quite write compliant extended names yet.
601 * som.c (som_slurp_extended_name_table): Delete function. The
602 generic code will handle things correctly.
603 (som_slurp_armap): Seek to the beginning of the next member.
604 (normalize): New function.
605 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
606 name table into account when computing the file offsets in the
607 SOM dictionary. Make sure to align to an even boundary.
608 (som_write_armap): Initialize the checksum to zero.
609 (ar_maxchars): Fix. Opps.
611 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
613 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
614 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
616 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
618 * bfd-in.h (BFD_VERSION): Use @VERSION@.
619 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
620 * bfd-in2.h: Regenerated.
622 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
623 this was also named trad_unix_bfd_copy_private_bfd_data.
625 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
627 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
628 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
629 returns NULL, it is not an error. It's possible that some of
630 these checks are not necessary (because the size can never be
631 zero), but putting in the checks is the conservative thing to do
632 in light of the fact that some of these malloc calls replaced
633 unchecked alloca calls, in which a zero argument would work fine.
635 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
637 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
638 duplicate definition.
639 (osf_core_bfd_is_local_label): Define.
641 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
642 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
643 failure indication, it merely means there are no relocs.
645 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
646 after NAME, since SunOS /bin/cc can't handle it.
648 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
650 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
651 From sukes@glue.umd.edu (Tasuki Hirata).
653 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
655 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
656 all that convoluted stuff with NAME, CAT3, etc. The convoluted
657 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
659 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
661 * som.c (som_prep_for_fixups): Detect section symbols based
662 on either the lack of private data or the symbol flags. Do not
663 munge section symbol names anymore -- they no longer confuse GDB.
664 (som_begin_writing): Leave space for an exec header if writing
666 (som_slurp_symbol_table): Recognize both forms of section symbol
667 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
668 section symbols to be the name of the section they represent.
669 Debugging symbols begin with "L$0\001", not just "L$".
671 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
673 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
675 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
676 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
677 and bfd_is_local_label.
679 * targets.c: Add new entries to the bfd_target structure.
681 * bfd.c (bfd_copy_private_bfd_data): New definition.
683 * section.c (bfd_copy_private_section_data): New definition.
685 * syms.c (bfd_is_local_label): New definition.
687 * libbfd-in.h (bfd_generic_is_local_label): Declare.
689 * libbfd.c (bfd_generic_is_local_label): New function.
691 * *-core.c: Provide default definitions for new functions in
692 the target vector which all point to bfd_false.
694 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
695 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
696 Default new vectors for copying private backend data to bfd_true.
697 Default new vector for determining if a symbol is a local label
698 to bfd_generic_is_local_label.
700 * som.c (som_bfd_copy_private_section_data): New function.
701 (som_bfd_is_local_label): New function.
702 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
704 * elf32-hppa.c (hppa_elf_is_local_label): New function.
706 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
708 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
710 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
713 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
714 Indent some of them to GNU standards.
716 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
717 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
718 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
719 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
720 Update copyright years.
722 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
724 * som.c (som_prep_for_fixups): A relocation involving the section
725 symbol for the *ABS* section is really a relocation involving
727 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
728 undefined symbols. Correctly distinguish between debugger symbols
731 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
732 for spaces and subspaces.
734 * som.c (som_bfd_count_ar_symbols): Fix typo.
736 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
737 HAS_RELOC based on the object's magic number.
738 (make_unique_section): Delete function. BFD and its users are
739 prepared to handle multiple sections with the same name.
740 (setup_sections): Allocate space on the BFD's obstack to hold
741 section names. Use bfd_make_setion_anyway rather than the
742 obsolete make_unique_section.
743 (som_prep_headers): Choose the correct SOM magic number based
745 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
747 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
749 * elf32-ppc.c: Renamed from elf32-powerpc.c.

759 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
761 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
762 is always located at the start of the data section to allow
763 recovery of the dynamic info from a stripped executable.
764 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
767 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
769 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
770 cruft (like the #pragma alloca for AIX).
771 In addition to that problem, the C alloca calls xmalloc, which
772 means checking for being out of memory can't work right. The
773 following changes remove all uses of alloca from BFD.
774 * hosts/solaris2.h: Remove alloca cruft.
775 * som.c: Replace alloca with a fixed size auto array.
776 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
777 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,

788 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
790 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
791 Elf*_Off typedefs by their expansion, the typedefs have been
792 removed from include/elf/internal.h.
793 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
794 SHT_PROGBITS section.
796 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
798 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
800 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
802 * configure.host: Recognize i[34]86-sequent-*.
804 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
805 return from bfd_seek indicates an error.
806 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
807 TRAD_CORE_STACK_OFFSET.
808 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
809 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
811 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
813 * som.[ch]: Do not include libhppa.h in som.c, instead include
816 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
817 include it in elf32-hppa.h.
819 * som.c (log2): Return -1 on error rather than aborting.
820 (setup_sections): Bubble up an error from log2.
822 * Changes to make HP C compiler happy in both traditional
824 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
826 (bfd_som_set_section_attributes): Use unsigned int rather than
827 unsigned char to avoid GNU-C extensions.
828 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
829 or failure rather than aborting on failure.
831 * som.h (bfd_som_set_section_attributes): Fix prototype to match
833 (bfd_som_attach_aux_hdr): Add prototype.
834 (hppa_som-gen_reloc_type): Likewise.
836 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
837 (hppa_look_for_stubs_in_section): Do not return false on failure
838 until rest of code is ready to handle it. Abort for now.
840 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
842 * bfd-in2.h: Rebuilt.
844 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
846 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
847 * Makefile.in: delete an extra blank.
848 * configure.in : Add i396os9k_vec.
850 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)

856 * Makefile.in : Handle new file i386os9k.c
857 * targets.c : Add bfd_target_os9k_flavour and i386os9k_vec.
858 * cache.c : Initialize cache_sentinel to 0.

862 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
863 action in case where caller specified no argument relocation.
864 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr

868 unused symbols argument.
870 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
871 than asymbol * for original target symbol. All callers changed.
872 Set reloc->sym_ptr_ptr appropriately.
873 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
874 (hppa_elf_look_for_stubs_in_section): No longer need symbols
875 argument. Use the output symbols when canonicalizing the relocs,
876 creating them if necessary.
878 * linker.c (_bfd_generic_link_output_symbols): Do not
879 rebuild/clobber the output symbols if they already exist.
881 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
883 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
884 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
885 * bfd-in2.h: Rebuilt.
887 * srec.c (hex_value): Always set to a size of 256 bytes.
888 (srec_init): Cosmetic changes.
890 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
892 * elf32-hppa.c: Second half of major cleanup. More comments,
893 PARAMize and staticize rest of functions. Delete unused
894 functions. Delete unused/unnecessary arguments to some functions.
895 Group static vars together. Abort for bad errors until we have
896 error code propogation working. Work on spacing and indention.
897 Add FIXMEs for unresolved problems. Use enums rather than
898 #defines for lots of things. Merge two functions which build
899 linker stubs into a single function (so they can easily share a
902 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
904 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
905 avoid depending upon right shifts of signed numbers, and to
906 correct handling of src_mask with lower bits zero.
908 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
909 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.

911 * elfcode.h (bfd_section_from_shdr): Make i unsigned; remove old
913 (elf_write_phdrs): Make i unsigned.
914 (map_program_segments): Make i and n_left unsigned.
915 (assign_file_positions_except_relocs): Make i unsigned.
916 (write_shdrs_and_ehdr): Make count unsigned.

1831 The sparc (and possibly other?) NLM format requires a different
1832 way to write exports, so add a write_export field to the backend
1833 data (and set it to NULL for everything but the sparc).

3117 terms of MY, because that causes a recusive invocation of CAT when
3118 expanded within JUMP_TABLE, and ANSI compilers don't expand
3120 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
3121 MY_reloc_howto_type_lookup, and don't define in terms of MY.
3122 (MY_canonicalize_reloc): Don't define in terms of MY.
3123 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
3124 than listing functions.
