d = vec_mergeh(a, b)Merges
the most significant ("high") halves of two vectors.
Figure 1. Merge 2 high-order elements (32-bit)
Assume that the elements of each vector are numbered beginning with 0. The even-numbered elements of the result are taken, in order, from the elements in the most significant half of a. The odd-numbered elements of the result are taken, in order, from the elements in the most significant half of b.
