// 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
-// for equality are legal.

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