511 in executables left by the HP linker. Does not rely on subspace
512 alignments as subspaces are *NOT* guaranteed to be properly

515 Sat Mar 26 10:25:43 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
517 * som.c (som_get_section_contents): New function. Do not try

693 "//" as the name of the special archive member holding the
696 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
698 Support for link_order types which generate relocs in order to
699 support -Ur in the linker.
700 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
701 from call to _bfd_generic_link_add_one_symbol.
702 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
703 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
704 instead of bitsize to add_to_set call back.
705 (_bfd_generic_final_link): Account for link_order relocs when
706 allocating space for relocations. Handle them in link_order loop.
707 (_bfd_generic_reloc_link_order): New function.
708 (_bfd_default_link_order): If a reloc_link_order is seen here,
710 (_bfd_count_link_order_relocs): New function.

730 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
732 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
734 * sunos.c (sunos_read_dynamic_info): Remove unused locals dynsym
737 * cisco-core.c (cisco_core_file_p): Only pass one argument to
738 bfd_zmalloc. Free a pointer, not a union.
739 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
741 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
743 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
745 * som.c (bfd_section_from_som_symbol): Only to do the value
746 comparison for function symbols within executables.
748 * som.c (bfd_section_from_som_symbol): Renamed from
749 som_section_from_subspace_index. Pass in a native SOM symbol.
750 For executables, iterate through the sections to find out
751 which contains the symbol's address rather than using the
752 symbol_info field. (symbol_info has a different meaning for
753 dynamicly linked executables.)
755 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
758 * som.c (som_begin_writing): Fix braino (one call to align
759 space/subspace data was done unconditionally rather than
760 just for executables.)
762 * som.c (som_begin_writing): Align text in all executables to
763 make HPUX kernel happy. Fixes strip/objcopy for shared
766 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
768 * som.c (som_begin_writing): Account for alignment needs of
769 subspaces too when writing executables. Never request a negative
770 bss size. Fixes some problems with demand paged executables,
771 still having problems with pure executables and shared executables.
773 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
775 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
776 bfd_zalloc for rawptr, because later on we may call free, not
779 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
780 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
781 * cisco-core.c: New file.

783 * configure.in: Recognize cisco_core_vec.
784 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
785 * targets.c: Add cisco_core_vec.
786 * bfd-in2.h: Rebuilt.
788 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
790 * som.h (som_copyable_section_data_struct): New structure
791 containing all the private section information which needs
792 to be copied from input section to output section during
794 (som_section_data_struct): Remove several fields now in
795 som_copyable_section_data_struct. Make the space and
796 subspace dictionaries be pointers (to save space when
797 only reading objects).
799 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
800 some references changed. Allocate a copyable data stucture if
801 none exists. Store info into the copyable data structure.
802 (bfd_som_set_subsection_attributes): Likewise.
803 (som_is_space, som_is_subspace, som_is_container): New functions.
804 Use these instead of directly accessing private data.
805 (som_prep_headers): Allocate space and subspace headers here.
806 Fill in some fields in the space/subspace headers from the
808 (som_bfd_copy_private_section_data): Only copy the stuff
809 that we really need to make objcopy and strip work. Allocate
810 the copy_data structure for the output bfd before copying.
812 * som.h (struct som_exec_data): New structure to hold exec
813 info that must be preserved when running objcopy/strip.
814 (struct somdata): Add new "exec_data" field and accessor
815 macro. Add some comments on how the various fields are used.
816 (som_section_data_struct): Make is_space and is_subspace bitfields.
817 Delete unused subspace_index. All references now use the
818 target_index field within the section structure itself.
820 * som.c (make_unique_section): Delete unused declaration.
821 (som_bfd_copy_private_bfd_data): New function.
822 (som_object_setup): Allocate space for and save exec information
823 that needs to be copied during objcopy/strip.
824 (som_mkobject): Do not allocate space for a file header here.
825 It is not used when only reading SOM objects.
826 (som_prep_headers): Allocate space for and attach a file header
827 to the output bfd. For executables, use the saved system_id
828 value rather than trying to guess the right value. Do not abort
829 wwhen setting file_hdr->entry* for executables.
830 (som_begin_writing): For executables, set the exec_entry and
832 (som_copy_private_backend_section_data): Always return a value.
834 * libhppa.h (PA_PAGESIZE): Define.
836 * som.c (SOM_ALIGN): Define.
837 (som_begin_writing): If writing an executable, initialize all
838 fields in the exec header to zero. Update fields in the exec
839 header as sizes of loadable subspaces are computed. Carefully
840 preserve alignments when building executables. Actually write the
841 exec after all the fields are filled in.
843 * Better long-filename handling. Reads SOM ABI compliant extended
844 names, but doesn't quite write compliant extended names yet.
845 * som.c (som_slurp_extended_name_table): Delete function. The
846 generic code will handle things correctly.
847 (som_slurp_armap): Seek to the beginning of the next member.
848 (normalize): New function.
849 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
850 name table into account when computing the file offsets in the
851 SOM dictionary. Make sure to align to an even boundary.
852 (som_write_armap): Initialize the checksum to zero.
853 (ar_maxchars): Fix. Opps.
855 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
857 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
858 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
860 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
862 * bfd-in.h (BFD_VERSION): Use @VERSION@.
863 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
864 * bfd-in2.h: Regenerated.
866 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
867 this was also named trad_unix_bfd_copy_private_bfd_data.
869 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
871 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
872 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
873 returns NULL, it is not an error. It's possible that some of
874 these checks are not necessary (because the size can never be
875 zero), but putting in the checks is the conservative thing to do
876 in light of the fact that some of these malloc calls replaced
877 unchecked alloca calls, in which a zero argument would work fine.
879 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
881 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
882 duplicate definition.
883 (osf_core_bfd_is_local_label): Define.
885 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
886 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
887 failure indication, it merely means there are no relocs.
889 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
890 after NAME, since SunOS /bin/cc can't handle it.
892 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
894 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
895 From sukes@glue.umd.edu (Tasuki Hirata).
897 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
899 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
900 all that convoluted stuff with NAME, CAT3, etc. The convoluted
901 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).

1014 cruft (like the #pragma alloca for AIX).
1015 In addition to that problem, the C alloca calls xmalloc, which

1358 unrelocated contents, the section's raw size is always the one to
1359 use for bounds checking.

1362 link_order size field against cooked size, not raw size, of input
1365 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
1367 (aligncode): When shrinking, the addend should be set to the
1368 current offset in the section plus the number of bytes of padding
1369 that will actually be retained.
1370 (b_out_relax_section): If a section contains no relocations, don't
1371 bother processing them.
1372 (b_out_get_relocated_section_contents): Set reloc_done. Assert
1373 that bfd_get_section_contents returns true. Check that relocs are
1375 (b_out_get_relocated_section_contents, case ALIGNDONE): Assert
1376 that reloc->addend falls between the current source offset and the
1377 raw size of the input section.
1379 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
1380 bout. Default with no version number is still bout. Support
1381 explicit i960-coff target too.

1859 _bfd_generic_link_write_global_symbol): Don't require that all
1860 references to a common symbol be themselves common symbols.

1905 (only testing for m68k and vax at the moment); do verify that the
1906 preprocessor didn't trash the arch name inside the string version.

2048 undefined, look it up in the linker hash table.
2050 * aoutx.h (translate_symbol_table): The string index 0 has a

2075 The sparc (and possibly other?) NLM format requires a different
2076 way to write exports, so add a write_export field to the backend
2077 data (and set it to NULL for everything but the sparc).
