◆ getAddressAccessSCEV()

const SCEV * getAddressAccessSCEV	(	const VPValue *	Ptr,
		PredicatedScalarEvolution &	PSE,
		const Loop *	L )

static

Returns a SCEV expression for Ptr if it is a pointer computation for which the legacy cost model computes a SCEV expression when computing the address cost.

Computing SCEVs for VPValues is incomplete and returns SCEVCouldNotCompute in cases the legacy cost model can compute SCEVs. In those cases we fall back to the legacy cost model. Otherwise return nullptr.
