[Bug rtl-optimization/32463] [4.1 Regression] bitwise shift optimization error



------- Comment #3 from rguenth at gcc dot gnu dot org  2008-01-13 12:53 -------
This is fixed in newer releases.  Note that while the code overflows the signed
bitfield, it is still valid as the bitfield is integer promoted before each
operation.

Maybe fixed by the fix for PR30274.
