            Bug ID: 99069
           Summary: Failure to optimize bool selection pattern
           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 x, bool y)
{
    return (x ? y : false) ? x : false;
}

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