Function safe_arch::insert_f32_imm_m128

pub fn insert_f32_imm_m128<const IMM: i32>(a: m128, b: m128) -> m128

Available with target feature sse4.1 only.

Inserts a lane from $b into $a, optionally at a new position.

Also, you can zero out any lanes you like for free as part of the same operation. If you don’t specify the mask argument then no lanes are zeroed.

let a = m128::from_array([1.0, 2.0, 3.0, 4.0]);
let b = m128::from_array([5.0, 6.0, 7.0, 8.0]);
//
let c = insert_f32_imm_m128::<0b00_11_0000>(a, b).to_array();
assert_eq!(c, [1.0, 2.0, 3.0, 5.0]);
//
let c = insert_f32_imm_m128::<0b00_11_0110>(a, b).to_array();
assert_eq!(c, [1.0, 0.0, 0.0, 5.0]);
