struct SCEVCouldNotCompute

Declaration

struct SCEVCouldNotCompute : public SCEV { /* full declaration omitted */ };

An object of this class is returned by queries that could not be answered. For example, if you ask for the number of iterations of a linked-list traversal loop, you will get one of these. None of the standard SCEV operations are valid on this class, it is just a marker.
