simdpp::shuffle4x2

template<unsigned s0, unsigned s1, unsigned s2, unsigned s3, unsigned N, class E1, class E2> Ret<N,_DETAIL_> shuffle4x2( const Vec1<N,E1>& a, const Vec2<N,E2& b );

Shuffles two vectors at 4x4 element block granularity.

The implementation behaves as if the following set of overloads is provided:

`Ret`	`Vec1`	`Vec2`
promoted 32-bit vector	any 32-bit vector	any 32-bit vector
promoted 64-bit vector	any 64-bit vector	any 64-bit vector

The type of the return vector is governed by the expression promotion rules. The return type is a vector expression.

The selectors s0, s1, s2 and s3 must be in range [0..7].

The vectors are shuffled at 4x4 block granularity as follows: the vectors are partitioned into N/4 groups. The n-th group in the return vector will contain:

elements only from n-th groups of a and b vectors
the 0-th, 1-st, 2-nd and 3-rd elements are selected by the s0, s1, s2 and s3 selectors respectively
values 0..3 correspond to the 0..3-th elements from n-th group from a, 4..7 correspond to the 0..3-th elements from n-th group from b.
