public class VerifyDeoptFrameStatesLIRPhase
extends org.graalvm.compiler.lir.phases.PostAllocationOptimizationPhase

Verification that deoptimization target frame states do not have live values that are not in the state, i.e., that do not correspond to a Java local variable or expression stack value. Such live values would not be restored during deoptimization, so the value would be undefined after deoptimization.
