        * lra-eliminations.c (move_plus_up): Don't change anything if either
        the outer or inner subreg mode is not MODE_INT.
        * dwarf2out.c (mem_loc_descriptor): For SUBREG, if outer mode is
        integral <= DWARF2_ADDR_SIZE, convert to untyped afterwards.

        * gcc.dg/guality/pr69244.c: New test.
