            Bug ID: 95923
           Summary: Failure to optimize bool checks into and
           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: ---

bool f(bool a, bool b)
{
    if (!a && !b)
        return 0;
    if (!a && b)
        return 0;
    if (a && !b)
        return 0;
    return 1;
}

This can be optimized to `return a & b;`. This transformation is done by LLVM,
but not by GCC.
