--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
With ashift:QI pattern, the shifter is defined as truncated with
SHIFT_COUNT_TRUNCATED turned on.  But the instruction which the back-end uses
does not have that property so it is the back-end lying to the middle-end
again.  So a target bug.
