--- Comment #11 from wilco at gcc dot gnu.org ---
Bin mentioned that the vectorizer could first try vectorizing loops and if that
fails unroll them given that vectorization is a special kind of unrolling. All
the infrastructure is already there given it can emit unrolled
alignment/trailing loops and has done the analysis already.
