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

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

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

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

864 unused symbols argument.
866 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
867 than asymbol * for original target symbol. All callers changed.
868 Set reloc->sym_ptr_ptr appropriately.
869 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
870 (hppa_elf_look_for_stubs_in_section): No longer need symbols
871 argument. Use the output symbols when canonicalizing the relocs,
872 creating them if necessary.
874 * linker.c (_bfd_generic_link_output_symbols): Do not
875 rebuild/clobber the output symbols if they already exist.
877 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
879 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
880 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
881 * bfd-in2.h: Rebuilt.
883 * srec.c (hex_value): Always set to a size of 256 bytes.
884 (srec_init): Cosmetic changes.
886 Sun Feb 27 11:18:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
888 * elf32-hppa.c: Second half of major cleanup. More comments,
889 PARAMize and staticize rest of functions. Delete unused
890 functions. Delete unused/unnecessary arguments to some functions.
891 Group static vars together. Abort for bad errors until we have
892 error code propogation working. Work on spacing and indention.
893 Add FIXMEs for unresolved problems. Use enums rather than
894 #defines for lots of things. Merge two functions which build
895 linker stubs into a single function (so they can easily share a
898 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
900 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
901 avoid depending upon right shifts of signed numbers, and to
902 correct handling of src_mask with lower bits zero.
904 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
905 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
906 * elf32-i386.c: Likewise.
907 * elfcode.h (bfd_section_from_shdr): Make i unsigned; remove old
909 (elf_write_phdrs): Make i unsigned.
910 (map_program_segments): Make i and n_left unsigned.
911 (assign_file_positions_except_relocs): Make i unsigned.
912 (write_shdrs_and_ehdr): Make count unsigned.
913 (assign_file_positions_for_relocs): Make i unsigned.
914 (NAME(bfd,elf_write_object_contents)): Make count unsigned.
915 (section_from_elf_index): Make index argument unsigned.
917 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)

1827 The sparc (and possibly other?) NLM format requires a different
1828 way to write exports, so add a write_export field to the backend
1829 data (and set it to NULL for everything but the sparc).
