class SCEVPtrToIntSinkingRewriter

Declaration

class SCEVPtrToIntSinkingRewriter : public SCEVRewriteVisitor { /* full declaration omitted */ };

Description

The SCEVPtrToIntSinkingRewriter takes a scalar evolution expression, which computes a pointer-typed value, and rewrites the whole expression tree so that *all* the computations are done on integers, and the only pointer-typed operands in the expression are SCEVUnknown.
