arch:: x86_64:: _mm_sad_epu8
pub unsafe fn _mm_sad_epu8(a: __m128i, b: __m128i) -> __m128i
Sum the absolute differences of packed unsigned 8-bit integers.
Computes the absolute differences of packed unsigned 8-bit integers in
b, then horizontally sum each consecutive 8 differences to produce
two unsigned 16-bit integers, and pack these unsigned 16-bit integers in
the low 16 bits of 64-bit elements returned.
