--- Comment #6 from YunQiang Su <syq at gcc dot gnu.org> ---
In RTL (xx.c.256r.expand), there is=20

(insn 10 9 11 2 (set (zero_extract:DI (reg/v:DI 200 [ val ])
            (const_int 8 [0x8])
            (const_int 0 [0]))
        (subreg:DI (reg:QI 202) 0)) "xx.c":4:29 -1
     (nil))


Maybe, it wrong as the mode cannot show the real length of val.=
