Available on
target_family="wasm"
and target feature simd128
and WebAssembly only.Expand description
Same as i8x16_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 i8x16.shuffle
instruction, since there
is no native i32x4.shuffle
instruction (there is no need for one since
i8x16.shuffle
suffices).
