createRootNode

protected org.graalvm.compiler.truffle.runtime.OptimizedOSRLoopNode.AbstractLoopOSRRootNode createRootNode(com.oracle.truffle.api.frame.FrameDescriptor rootFrameDescriptor,
                                                                                                           Class<? extends com.oracle.truffle.api.frame.VirtualFrame> clazz)

Parameters:

rootFrameDescriptor - may be null.

copy

public final com.oracle.truffle.api.nodes.Node copy()

Overrides:

copy in class com.oracle.truffle.api.nodes.Node

execute

public Object execute(com.oracle.truffle.api.frame.VirtualFrame frame)

Overrides:

execute in class com.oracle.truffle.api.nodes.LoopNode

forceOSR

public final void forceOSR()

Forces OSR compilation for this loop.

getCompiledOSRLoop

public final OptimizedCallTarget getCompiledOSRLoop()

nodeReplaced

public final boolean nodeReplaced(com.oracle.truffle.api.nodes.Node oldNode,
                                  com.oracle.truffle.api.nodes.Node newNode,
                                  CharSequence reason)

Specified by:
