--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
Complete peeling is known of not eliminating all unreachable code which is why
-Warray-bounds now runs _before_ unrolling only.  Note it's practically
impossible to cover all cases in peeling but there's some that could
(identified in some old PR I can't find right now).
