--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
this was exposed by my commit (r14-3350-g47b833a9abe1) which added:
/* Likewise for view_convert of nop_conversions. */
(simplify
 (view_convert (vec_cond:s @0 @1 @2))
 (if (VECTOR_TYPE_P (type) && VECTOR_TYPE_P (TREE_TYPE (@1))
      && known_eq (TYPE_VECTOR_SUBPARTS (type),
                   TYPE_VECTOR_SUBPARTS (TREE_TYPE (@1)))
      && tree_nop_conversion_p (TREE_TYPE (type), TREE_TYPE (TREE_TYPE (@1))))
  (vec_cond @0 (view_convert! @1) (view_convert! @2))))

Before we have a VIEW_CONVERT around the vec_cond which prevented the infinite
loop but now we don't ...
