      Description

        The AD matching for loadBarrierWeakSlowRegNoVec is incorrect. It should match against a LoadBarrierWeakSlowReg, not LoadBarrierSlowReg. This can lead to incorrect barrier slow path being generated (weak instead of strong), which is really bad.

        Also the format lines for loadBarrier*SlowRegXmmAndYmm are missing the "AndYmm" part.
