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