        * function.c (purge_addressof_1): Instead of aborting when a
        bitfield insertion as a replacement for (MEM (ADDRESSOF)) does not
        work just put the ADDRESSOF on stack.  Otherwise remember all such
        successfull replacements, so that exactly the same replacements
        can be made on the REG_NOTEs.  Remove the special case for CALL
        insns again.
        (purge_addressof_replacements): New variable.
        (purge_addressof): Clear it at end.
