fn pshufb<'tcx>(
ecx: &mut MiriInterpCx<'tcx>,
left: &OpTy<'tcx>,
right: &OpTy<'tcx>,
dest: &MPlaceTy<'tcx>,
) -> InterpResult<'tcx, ()>Expand description
Shuffles bytes from left using right as pattern. Each 16-byte block is shuffled independently.
left and right are both vectors of type len x i8.
If the highest bit of a byte in right is not set, the corresponding byte in dest is taken
from the current 16-byte block of left at the position indicated by the lowest 4 bits of this
byte in right. If the highest bit of a byte in right is set, the corresponding byte in
dest is set to 0.
