only.Shuffle the i32
lanes in $a
using an immediate control value.
Each lane selection value picks only within that 128-bit half of the overall register.
let a = m256i::from([5, 6, 7, 8, 9, 10, 11, 12]); let b: [i32; 8] = shuffle_ai_i32_half_m256i!(a, [3, 2, 1, 0]).into(); assert_eq!(b, [8, 7, 6, 5, 12, 11, 10, 9]);
