--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Actually the vectorizer punts on the comparisons itself.  The pattern
recognizer handles some of them as

  patt_10 = _4 > 0.0 ? 1 : 0;

but not those feeding the BIT expressions which would need to be widened then
(though they are supported as bit-precision).
