Function swap¶

`function` swap(const vec<T, N> &) simd ¶

template <size_t elements = 2, typename T, size_t N>
KFR_INTRINSIC vec<T, N> swap(const vec<T, N>& x)

Swaps adjacent groups of elements lanes.

For elements == 2, pairs of adjacent lanes are swapped. More generally, blocks of elements consecutive lanes are swapped pairwise.

Template parameters
elements	Number of lanes in each block to swap.
T	Element type of the vector.
N	Input vector length.

Parameters
x	Source vector.

Returns
	A vector of length `N` with adjacent `elements-sized` blocks swapped.

Fully qualified name: kfr::swap(const vec<T, N> &)
