--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
On GIMPLE there's nothing wrong I think.  There's some inconsistency in
representing a splat where when we have a scalar source we use a CONSTRUCTOR
but when we have a (multi-use) vector we use a VEC_PERM to splat its
first element (but I guess that's actually good in the end).
