And, in addition to this, it might be good to see how it's vectorized for the interleaved accesses (especially how the intrinsics/shuffles "interaction" looks like), e.g (similar to interleaved-accesses-1.ll).

  struct S {
    int * restrict i;
    float * restrict f;
  };

  S *p1, *p2;
  for (int j = 0; j < N; ++j) {
    S t = p1[j];
    p2[j] = t;
  }
