            Bug ID: 96707
           Summary: Failure to optimize right shift+unsigned compare of
                    two variables optimally
           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(unsigned x, unsigned y)
{
    return (x >> y) <= x;
}

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