            Bug ID: 109605
           Summary: -fno-tree-vectorize does not disable vectorizer
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hubicka at gcc dot gnu.org
  Target Milestone: ---

-ftree-vectorize enables -ftree-slp-vectorize and -ftree-loop-vectorize how=
ever
-fno-tree-vectorize does not disable them.  This is quite counter-intuitive=
 and
at least I got caught in this trap while doing some benchmarking.=
