Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|rtl-optimization |target --- 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.
