            Bug ID: 96694
           Summary: Failure to optimize min/max pattern using two binary
                    nots to min/max pattern using one binary not
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gabravier at gmail dot com
  Target Milestone: ---

int f(int x, int y)
{
    return ~((~x > y) ? ~x : y);
}

This can be optimized to `return ((~y <= x) ? ~y : x);`. This transformation is
done by LLVM, but not by GCC.
