Function safe_arch::shr_all_i32_m128i

#[must_use]pub fn shr_all_i32_m128i(a: m128i, count: m128i) -> m128i

This is supported with target feature sse2 only.

Shift each i32 lane to the right by the count in the lower i64 lane.

New bits are the sign bit.

let a = m128i::from([1_i32, 2, -3, -4]);
let b = m128i::from([3_i64, 0]);
let c: [i32; 4] = shr_all_i32_m128i(a, b).into();
assert_eq!(c, [1 >> 3, 2 >> 3, -3 >> 3, -4 >> 3]);
