    PR c++/55742
    * config/i386/i386.c (ix86_valid_target_attribute_inner_p): Diagnose
    invalid args instead of ICEing on it.
    (ix86_valid_target_attribute_tree): Return error_mark_node if
    ix86_valid_target_attribute_inner_p failed.
    (ix86_valid_target_attribute_p): Return false only if
    ix86_valid_target_attribute_tree returned error_mark_node.  Allow
    target("default") attribute.
    (sorted_attr_string): Change argument from const char * to tree,
    merge in all target attribute arguments rather than just one.
    Formatting fix.  Use XNEWVEC instead of xmalloc and XDELETEVEC
    instead of free.  Avoid using strcat.
    (ix86_mangle_function_version_assembler_name): Mangle
    target("default") as if no target attribute is present.  Adjust
    sorted_attr_string caller.  Avoid leaking memory.  Use XNEWVEC
    instead of xmalloc and XDELETEVEC instead of free.
    (ix86_function_versions): Don't return true if one of the decls
    doesn't have target attribute.  If they don't and one of the decls
    is DECL_FUNCTION_VERSIONED, report an error.  Adjust
    sorted_attr_string caller.  Use XDELETEVEC instead of free.
    (ix86_supports_function_versions): Remove.
    (make_name): Fix up formatting.
    (make_dispatcher_decl): Remove resolver_name and its initialization.
    Avoid leaking memory.
    (is_function_default_version): Return true if there is
    target("default") attribute rather than no target attribute at all.
    (make_resolver_func): Avoid leaking memory.
    (ix86_generate_version_dispatcher_body): Likewise.
    (TARGET_OPTION_SUPPORTS_FUNCTION_VERSIONS): Remove.
    * target.def (supports_function_versions): Remove.
    * doc/tm.texi.in (SUPPORTS_FUNCTION_VERSIONS): Remove.
    * doc/tm.texi: Regenerated.

    * c-common.c (handle_target_attribute): Revert 2012-12-26 change.
