 // There are several aspects to this library.  First is the representation of
 // scalar expressions, which are represented as subclasses of the SCEV class.
 // These classes are used to represent certain types of subexpressions that we
-// can handle.  These classes are reference counted, managed by the const SCEV *
-// class.  We only create one SCEV of a particular shape, so pointer-comparisons

 // One important aspect of the SCEV objects is that they are never cyclic, even
