[−][src]Macro safe_arch::shuffle_ai_f32_half_m256

macro_rules! shuffle_ai_f32_half_m256 {
    ($a:expr, [$z:expr, $o:expr, $t:expr, $h:expr]) => { ... };
}
This is supported with target feature avx only.

Shuffle the f32 lanes in $a using an immediate control value.

Each lane selection value picks only within that 128-bit half of the overall register. The same selection pattern is simply used for both the upper and lower 128 bits.

let a = m256::from_array([1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0]);
//
let b = shuffle_ai_f32_half_m256!(a, [3, 1, 2, 0]).to_array();
assert_eq!(b, [4.0, 2.0, 3.0, 1.0, 8.0, 6.0, 7.0, 5.0]);
