#[must_use]pub fn cmp_neq_mask_m128d_s(a: m128d, b: m128d) -> m128d

This is supported with target feature sse2 only.

Low lane a != b, other lane unchanged.

Mask output.

let a = m128d::from_array([2.0, 5.0]);
let b = m128d::from_array([1.0, 1.0]);
let c = cmp_neq_mask_m128d_s(a, b).to_bits();
assert_eq!(c, [u64::MAX, 5_f64.to_bits()]);
