#[must_use]pub fn cmp_gt_mask_i64_m128i(a: m128i, b: m128i) -> m128i

This is supported with target feature sse4.2 only.

Lanewise a > b with lanes as i64.

All bits 1 for true (-1), all bit 0 for false (0).

let a = m128i::from([1_i64, 3]);
let b = m128i::from([0_i64, 3]);
let c: [i64; 2] = cmp_gt_mask_i64_m128i(a, b).into();
assert_eq!(c, [-1_i64, 0]);
