            Bug ID: 96695
           Summary: Failure to optimize combination of pointer comparison
                    to nullptr and another pointer
           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(char *x, char *y)
{
    return (x == 0) && (x > y);
}

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