--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Both functions get the same IL, the convertvector destination type is lost.

;; Function FI (null)
;; enabled by -tree-original


{
  return VIEW_CONVERT_EXPR<GV>(.VEC_CONVERT (x));
}


;; Function JI (null)
;; enabled by -tree-original


{
  return VIEW_CONVERT_EXPR<GV>(.VEC_CONVERT (x));
}
