pub fn u64x2_shuffle<const I0: usize, const I1: usize>(a: v128, b: v128) -> v128🔬This is a nightly-only experimental API. (
simd_wasm64 #90599)Available on
target_family="wasm" and target feature simd128 only.Expand description
Same as i8x16_shuffle, except operates as if the inputs were two
64-bit integers, only taking 2 indices to shuffle.
Indices in the range [0, 1] select from a while [2, 3] select from b.
Note that this will generate the v8x16.shuffle instruction, since there
is no native i64x2.shuffle instruction (there is no need for one since
i8x16.shuffle suffices).
