Class RemoveUnwindPhase

java.lang.Object

org.graalvm.compiler.phases.BasePhase<Object>

org.graalvm.compiler.phases.Phase

com.oracle.svm.core.graal.phases.RemoveUnwindPhase

All Implemented Interfaces:

org.graalvm.compiler.phases.contract.PhaseSizeContract

public class RemoveUnwindPhase
extends org.graalvm.compiler.phases.Phase

The exception handling mechanism of Substrate VM is capable of jumping over methods that have no exception handler registered. That saves us from emitting boilerplate code in every call site in every method that just forwards the exception object from the WithExceptionNode to the UnwindNode.
