Class DynamicCounterNode

java.lang.Object

com.oracle.graal.graph.Node

com.oracle.graal.nodes.ValueNode

com.oracle.graal.nodes.FixedNode

com.oracle.graal.nodes.FixedWithNextNode

com.oracle.graal.nodes.debug.DynamicCounterNode

All Implemented Interfaces:

LIRLowerable, Cloneable, Formattable, KindProvider

Direct Known Subclasses:

WeakCounterNode

public class DynamicCounterNode
extends FixedWithNextNode
implements LIRLowerable

This node can be used to add a counter to the code that will estimate the dynamic number of calls by adding an increment to the compiled code. This should of course only be used for debugging/testing purposes. A unique counter will be created for each unique name passed to the constructor. Depending on the value of withContext, the name of the root method is added to the counter's name.
