--- Comment #6 from Ilya Enkovich <ienkovich at gcc dot gnu.org> --- I think we should disable vectorization of boolean comparison (except '==' and '!=') and handle them applying patterns. E.g. a > b ==> a & !b, a >= b ==> a | !b etc. Bitwise operations are better because work for both vector and scalar masks.
