Function core::arch::wasm32::v64x2_shuffle [−][src]
pub unsafe fn v64x2_shuffle<const I0: usize, const I1: usize>(
a: v128,
b: v128
) -> v128
This is supported on WebAssembly and target feature
simd128
only.Same as v8x16_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 v64x2.shuffle
instruction (there is no need for one since
v8x16.shuffle
suffices).
