+These nodes represent merging and interleaving of the high/low elements of the
+two input vectors, respectively. The operands and the result are vectors that
+contain the same number of elements (@code{N}) of the same type.
+In the case of @code{VEC_INTERLEAVE_HIGH_EXPR}, the high @code{N/2} elements of
+the first input vector are interleaved with the high @code{N/2} elements of the
+second input vector. In the case of @code{VEC_INTERLEAVE_LOW_EXPR}, the low
+@code{N/2} elements of the first input vector are interleaved with the low
+@code{N/2} elements of the second input vector.
