--- Comment #7 from Ingo Müller <2013.bugzilla.gcc.gnu.org at ingomueller dot net> ---
libiberty.a is still installed to /lib/libiberty.a in GCC 4.8.1, even with
--disable-install-libiberty set.

    * lto-cgraph.c (compute_ltrans_boundary): Add abstract origins into
    boundaries.
    * lto-streamer-out.c (tree_is_indexable): Results decls and
    parm decls are not indexable.
    (DFS_write_tree_body): Do not follow args and results.
    (hash_tree): Likewise.
    (output_functions): Rearrange so struct function is needed
    only when real body is output; be able to also ouptut abstract
    functions; output DECL_ARGUMENTS and DECL_RESULT.
    (lto_output): When not in WPA, ale store abstract functions.
    (write_symbol): Do not care about RESULT_DECL.
    (output_symbol_p): Handle correctly sbtract decls.
    * lto-streamer-in.c (input_function): Rearrange so struct
    function can be NULL at entry; allow streaming of
    functions w/o body; store DECL_ARGUMENTS and DECL_RESULT.
    * ipa.c (symtab_remove_unreachable_nodes): Silence confused
    sanity check during LTO.
    * tree-streamer-out.c (write_ts_decl_non_common_tree_pointers): Skip
    RESULT_DECl and DECL_ARGUMENTS.
    * tree-streamer-in.c (lto_input_ts_decl_non_common_tree_pointers):
    Likewise.
