All Implemented Interfaces:

PhaseSizeContract

public final class TruffleSafepointInsertionPhase
extends Phase

Adds Truffle safepoints to loops and methods ends. Invocations of TruffleSafepoint.poll(com.oracle.truffle.api.nodes.Node) are removed during PE. This phase ensures that they are efficiently added again at method and loop ends.
