5 ; Although we have the ability to fold an unaligned load with AVX
6 ; and under special conditions with some SSE implementations, we
7 ; can not fold the load under any circumstances in these test
8 ; cases because they are not 16-byte loads. The load must be
9 ; executed as a scalar ('movs*') with a zero extension to
10 ; 128-bits and then used in the packed logical ('andp*') op.
