Function rotatetwo¶
function rotatetwo(const vec<T, N> &, const vec<T, N> &) simd¶
template <size_t shift, typename T, size_t N>
KFR_INTRINSIC vec<T, N> rotatetwo(const vec<T, N>& lo, const vec<T, N>& hi)Combines two vectors lo and hi with a rotation by shift lanes.
The result is formed from the concatenation of lo (low) and hi (high), shifted right by shift positions. When shift == 0 the result is lo; when shift == N the result is hi.
| shift | Number of lanes to shift by, in [0, N]. |
| T | Element type of the vectors. |
| N | Length of each input vector. |
| lo | Low source vector. |
| hi | High source vector. |
A vector of length N drawn from the rotated concatenation of lo and hi. |
