pub unsafe fn _mm_hsubs_epi16(a: __m128i, b: __m128i) -> __m128i
This is supported on x86-64 and target feature
Horizontally subtract the adjacent pairs of values contained in 2
packed 128-bit vectors of
[8 x i16]. Positive differences greater than
7FFFh are saturated to 7FFFh. Negative differences less than 8000h are
saturated to 8000h.
