But the > execution doesn't even hit vect_init_vector. The patch wasn't supposed to make this case vectorized but fix the ICE. On targets where the vector mode is not supported it happens to also vectorize it. Making the vectorizer deal with existing vector types is a much harder task (I tried for a few hours but failed, there are too many rough spots to fix)
