Function core::arch::wasm32::v32x4_shuffle[][src]

pub unsafe fn v32x4_shuffle<const I0: usize, const I1: usize, const I2: usize, const I3: usize>(
    a: v128,
    b: v128
) -> v128
🔬 This is a nightly-only experimental API. (wasm_simd #74372)
This is supported on WebAssembly and target feature simd128 only.

Same as v8x16_shuffle, except operates as if the inputs were four 32-bit integers, only taking 4 indices to shuffle.

Indices in the range [0, 3] select from a while [4, 7] select from b. Note that this will generate the v8x16.shuffle instruction, since there is no native v32x4.shuffle instruction (there is no need for one since v8x16.shuffle suffices).
