        * tree-core.h (struct tree_decl_common): Document
        decl_nonshareable_flag for PARM_DECLs.
        * tree.h (DECL_HIDDEN_STRING_LENGTH): Define.
        * calls.c (expand_call): Don't try tail call if caller
        has any DECL_HIDDEN_STRING_LENGTH PARM_DECLs that are or might be
        passed on the stack and callee needs to pass any arguments on the
        stack.
        * tree-streamer-in.c (unpack_ts_decl_common_value_fields): Use
        else if instead of series of mutually exclusive ifs.  Handle
        DECL_HIDDEN_STRING_LENGTH for PARM_DECLs.
        * tree-streamer-out.c (pack_ts_decl_common_value_fields): Likewise.

        * trans-decl.c (create_function_arglist): Set
        DECL_HIDDEN_STRING_LENGTH on hidden string length PARM_DECLs if
        len is constant.
