29.10 Data-parallel types [simd]

29.10.8 basic_vec non-member operations [simd.nonmembers]

29.10.8.8 Dynamic permute [simd.permute.dynamic]

template<simd-vec-type V, simd-integral I>
  constexpr resize_t<I::size(), V> permute(const V& v, const I& indices);
template<simd-mask-type M, simd-integral I>
  constexpr resize_t<I::size(), M> permute(const M& v, const I& indices);

Returns: A data-parallel object where the

{i th element is initialized to the result of v [indices [i] for all i in the range [0, I ​::​ size ()) .}^{th element is initialized to the result of v [indices [i] for all i in the range [0, I ​::​ size ()) .}
