3 Changes to let BFD return an error indication from
4 get_symtab_upper_bound, bfd_canonicalize_symtab,
5 bfd_get_reloc_upper_bound, and bfd_canonicalize_reloc. They now
6 return long instead of unsigned int, and use -1 to indicate an
7 error. Along the way, rename get_symtab_upper_bound to
8 bfd_get_symtab_upper_bound.

412 * som.c (som_begin_writing): Align text in all executables to
413 make HPUX kernel happy. Fixes strip/objcopy for shared
414 executables.
415
416 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
417
418 * som.c (som_begin_writing): Account for alignment needs of
419 subspaces too when writing executables. Never request a negative
420 bss size. Fixes some problems with demand paged executables,
421 still having problems with pure executables and shared executables.
422
423 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
424
425 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
426 bfd_zalloc for rawptr, because later on we may call free, not
427 bfd_release, on it.
428
429 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
430 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
431 * cisco-core.c: New file.
432 * Makefile.in: Change accordingly.
433 * configure.in: Recognize cisco_core_vec.
434 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
435 * targets.c: Add cisco_core_vec.
436 * bfd-in2.h: Rebuilt.
437
438 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
439
440 * som.h (som_copyable_section_data_struct): New structure
441 containing all the private section information which needs
442 to be copied from input section to output section during
443 objcopy or strip.
444 (som_section_data_struct): Remove several fields now in
445 som_copyable_section_data_struct. Make the space and
446 subspace dictionaries be pointers (to save space when
447 only reading objects).
448
449 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
450 some references changed. Allocate a copyable data stucture if
451 none exists. Store info into the copyable data structure.
452 (bfd_som_set_subsection_attributes): Likewise.
453 (som_is_space, som_is_subspace, som_is_container): New functions.
454 Use these instead of directly accessing private data.
455 (som_prep_headers): Allocate space and subspace headers here.
456 Fill in some fields in the space/subspace headers from the
457 copyable data.
458 (som_bfd_copy_private_section_data): Only copy the stuff
459 that we really need to make objcopy and strip work. Allocate
460 the copy_data structure for the output bfd before copying.
461
462 * som.h (struct som_exec_data): New structure to hold exec
463 info that must be preserved when running objcopy/strip.
464 (struct somdata): Add new "exec_data" field and accessor
465 macro. Add some comments on how the various fields are used.
466 (som_section_data_struct): Make is_space and is_subspace bitfields.
467 Delete unused subspace_index. All references now use the
468 target_index field within the section structure itself.
469
470 * som.c (make_unique_section): Delete unused declaration.
471 (som_bfd_copy_private_bfd_data): New function.
472 (som_object_setup): Allocate space for and save exec information
473 that needs to be copied during objcopy/strip.
474 (som_mkobject): Do not allocate space for a file header here.
475 It is not used when only reading SOM objects.
476 (som_prep_headers): Allocate space for and attach a file header
477 to the output bfd. For executables, use the saved system_id
478 value rather than trying to guess the right value. Do not abort
479 wwhen setting file_hdr->entry* for executables.
480 (som_begin_writing): For executables, set the exec_entry and
481 exec_flags fields.
482 (som_copy_private_backend_section_data): Always return a value.
483
484 * libhppa.h (PA_PAGESIZE): Define.
485
486 * som.c (SOM_ALIGN): Define.
487 (som_begin_writing): If writing an executable, initialize all
488 fields in the exec header to zero. Update fields in the exec
489 header as sizes of loadable subspaces are computed. Carefully
490 preserve alignments when building executables. Actually write the
491 exec after all the fields are filled in.
492
493 * Better long-filename handling. Reads SOM ABI compliant extended
494 names, but doesn't quite write compliant extended names yet.
495 * som.c (som_slurp_extended_name_table): Delete function. The
496 generic code will handle things correctly.
497 (som_slurp_armap): Seek to the beginning of the next member.
498 (normalize): New function.
499 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
500 name table into account when computing the file offsets in the
501 SOM dictionary. Make sure to align to an even boundary.
502 (som_write_armap): Initialize the checksum to zero.
503 (ar_maxchars): Fix. Opps.
504
505 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
506
507 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
508 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
509
510 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
511
512 * bfd-in.h (BFD_VERSION): Use @VERSION@.
513 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
514 * bfd-in2.h: Regenerated.
515
516 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
517 this was also named trad_unix_bfd_copy_private_bfd_data.
518
519 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
520
521 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
522 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
523 returns NULL, it is not an error. It's possible that some of
524 these checks are not necessary (because the size can never be
525 zero), but putting in the checks is the conservative thing to do
526 in light of the fact that some of these malloc calls replaced
527 unchecked alloca calls, in which a zero argument would work fine.
528
529 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
530
531 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
532 duplicate definition.
533 (osf_core_bfd_is_local_label): Define.
534
535 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
536 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
537 failure indication, it merely means there are no relocs.
538
539 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
540 after NAME, since SunOS /bin/cc can't handle it.
541
542 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
543
544 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

546
547 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
548
549 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
550 all that convoluted stuff with NAME, CAT3, etc. The convoluted
551 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
552
553 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
554
555 * som.c (som_prep_for_fixups): Detect section symbols based
556 on either the lack of private data or the symbol flags. Do not
557 munge section symbol names anymore -- they no longer confuse GDB.
558 (som_begin_writing): Leave space for an exec header if writing
559 an executable.
560 (som_slurp_symbol_table): Recognize both forms of section symbol
561 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
562 section symbols to be the name of the section they represent.
563 Debugging symbols begin with "L$0\001", not just "L$".
564
565 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
566
567 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
568
569 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
570 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
571 and bfd_is_local_label.
572
573 * targets.c: Add new entries to the bfd_target structure.
574
575 * bfd.c (bfd_copy_private_bfd_data): New definition.
576
577 * section.c (bfd_copy_private_section_data): New definition.
578
579 * syms.c (bfd_is_local_label): New definition.
580
581 * libbfd-in.h (bfd_generic_is_local_label): Declare.
582
583 * libbfd.c (bfd_generic_is_local_label): New function.
584
585 * *-core.c: Provide default definitions for new functions in
586 the target vector which all point to bfd_false.
587
588 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
589 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
590 Default new vectors for copying private backend data to bfd_true.
591 Default new vector for determining if a symbol is a local label
592 to bfd_generic_is_local_label.
593
594 * som.c (som_bfd_copy_private_section_data): New function.
595 (som_bfd_is_local_label): New function.
596 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
597
598 * elf32-hppa.c (hppa_elf_is_local_label): New function.
599
600 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
601
602 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
603
604 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
605
606 * Most files:
607 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
608 Indent some of them to GNU standards.
609
610 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
611 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
612 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
613 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
614 Update copyright years.
615
616 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
617
618 * som.c (som_prep_for_fixups): A relocation involving the section
619 symbol for the *ABS* section is really a relocation involving
620 no symbol.
621 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
622 undefined symbols. Correctly distinguish between debugger symbols
623 and section symbols.
624
625 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
626 for spaces and subspaces.
627
628 * som.c (som_bfd_count_ar_symbols): Fix typo.
629
630 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
631 HAS_RELOC based on the object's magic number.
632 (make_unique_section): Delete function. BFD and its users are
633 prepared to handle multiple sections with the same name.
634 (setup_sections): Allocate space on the BFD's obstack to hold
635 section names. Use bfd_make_setion_anyway rather than the
636 obsolete make_unique_section.
637 (som_prep_headers): Choose the correct SOM magic number based
638 on the BFD's flags.
639 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
640
641 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
642
643 * elf32-ppc.c: Renamed from elf32-powerpc.c.
644 start-sanitize-powerpc-netware
645 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
646 end-sanitize-powerpc-netware
647 * Makefile.in, configure.in: Corresponding changes.

652
653 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
654
655 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
656 is always located at the start of the data section to allow
657 recovery of the dynamic info from a stripped executable.
658 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
659 and STYP_COMMENT.
660
661 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
662
663 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
664 cruft (like the #pragma alloca for AIX).
665 In addition to that problem, the C alloca calls xmalloc, which
666 means checking for being out of memory can't work right. The
667 following changes remove all uses of alloca from BFD.
668 * hosts/solaris2.h: Remove alloca cruft.
669 * som.c: Replace alloca with a fixed size auto array.
670 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
671 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
672 sunos.c: Replace alloca with malloc and appropriate error checking and
673 freeing.
674 * linker.c: Replace alloca with obstack_alloc.
675 * libbfd.h: Rebuilt.
676
677 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
678
679 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
680 MIPS_R_GPREL.
681
682 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
683
684 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
685 Elf*_Off typedefs by their expansion, the typedefs have been
686 removed from include/elf/internal.h.
687 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
688 SHT_PROGBITS section.
689
690 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
691
692 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.
693
694 Wed Mar 2 13:28:06 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
695
696 * configure.host: Recognize i[34]86-sequent-*.
697
698 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
699 return from bfd_seek indicates an error.
700 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
701 TRAD_CORE_STACK_OFFSET.
702 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
703 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
704
705 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
706
707 * som.[ch]: Do not include libhppa.h in som.c, instead include
708 it in som.h.
709
710 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
711 include it in elf32-hppa.h.
712
713 * som.c (log2): Return -1 on error rather than aborting.
714 (setup_sections): Bubble up an error from log2.
715
716 * Changes to make HP C compiler happy in both traditional
717 and ANSI mode.
718 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
719 field parameter.
720 (bfd_som_set_section_attributes): Use unsigned int rather than
721 unsigned char to avoid GNU-C extensions.
722 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
723 or failure rather than aborting on failure.

731 (hppa_look_for_stubs_in_section): Do not return false on failure
732 until rest of code is ready to handle it. Abort for now.
733
734 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
735
736 * bfd-in2.h: Rebuilt.
737
738 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)
739
740 * i386os9k.c: use new functions bfd_set_error and bfd_get_error.
741 * Makefile.in: delete an extra blank.
742 * configure.in : Add i396os9k_vec.
743
744 Mon Feb 28 15:41:01 1994 Kung Hsu (kung@mexican.cygnus.com)

755
756 * elf32-hppa.c (mismatches, retval_mismatches): Fix mismatch
757 action in case where caller specified no argument relocation.
758 (hppa_elf_build_linker_stub): Try again to get the sym_ptr_ptr
759 right in the original relocation and the stub's relocation.
760
761 * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
762 unused symbols argument.
763
764 * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
765 than asymbol * for original target symbol. All callers changed.
766 Set reloc->sym_ptr_ptr appropriately.
767 (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
768 (hppa_elf_look_for_stubs_in_section): No longer need symbols
769 argument. Use the output symbols when canonicalizing the relocs,
770 creating them if necessary.
771
772 * linker.c (_bfd_generic_link_output_symbols): Do not
773 rebuild/clobber the output symbols if they already exist.
774
775 Sun Feb 27 15:22:36 1994 Stan Shebs (shebs@andros.cygnus.com)
776
777 * targets.c (BFD_SEND, BFD_SEND_FMT): Add debugging versions that
778 check all the pointer dereferences. Enabled via DEBUG_BFD_SEND.
779 * bfd-in2.h: Rebuilt.

785
786 * elf32-hppa.c: Second half of major cleanup. More comments,
787 PARAMize and staticize rest of functions. Delete unused
788 functions. Delete unused/unnecessary arguments to some functions.
789 Group static vars together. Abort for bad errors until we have
790 error code propogation working. Work on spacing and indention.
791 Add FIXMEs for unresolved problems. Use enums rather than
792 #defines for lots of things. Merge two functions which build
793 linker stubs into a single function (so they can easily share a
794 ton of common code).
795
796 Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
797
798 * reloc.c (_bfd_relocate_contents): Adjust handling of overflow to
799 avoid depending upon right shifts of signed numbers, and to
800 correct handling of src_mask with lower bits zero.
801
802 * aoutx.h, archive.c: Add casts to avoid warnings from SVR4 cc.
803 * ecoff.c, ecofflink.c, ecoffswap.h, srec.c: Likewise.
804 * elf32-i386.c: Likewise.
805 * elfcode.h (bfd_section_from_shdr): Make i unsigned; remove old
806 #if 0 code.

814
815 Fri Feb 25 21:34:58 1994 Ian Lance Taylor (ian@cygnus.com)
816
817 * elfcode.h: Don't include assert.h.
818 (swap_out_syms): Use BFD_ASSERT rather than assert.
819
820 * linker.c (_bfd_generic_link_write_global_symbol): Add missing
821 break in switch.

834 * elf32-hppa.c: First half of major cleanup. Add/cleanup lots of
835 comments. PARAMize some static functions. Delete unused functions.
836 Delete unused/unnecessary arguments to many functions. Group
837 static vars together. Collapse common case statements together

1034 fixed some comments, removed some "#if 1" lines.

1107 check the result for NULL. Most set bfd_error to no_memory and

1553
1554 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros

1771 return value.
1772 * aoutf1.h (NAME(aout,sunos4_write_object_contents)): Don't write
1773 out dynamic symbols or relocs against reloc symbols, since they
1774 are already in the .text section and we wouldn't know where to
1775 write them anyhow.
