Class ControlSplitNode

java.lang.Object

com.oracle.graal.graph.Node

com.oracle.graal.nodes.ValueNode

com.oracle.graal.nodes.FixedNode

com.oracle.graal.nodes.ControlSplitNode

All Implemented Interfaces:

IterableNodeType, Cloneable, Formattable, KindProvider

Direct Known Subclasses:

IfNode, IntegerExactArithmeticSplitNode, InvokeWithExceptionNode, SwitchNode

public abstract class ControlSplitNode
extends FixedNode
implements IterableNodeType

The ControlSplitNode is a base class for all instructions that split the control flow (ie. have more than one successor).

Method Detail

probability

public abstract double probability(AbstractBeginNode successor)

getPrimarySuccessor

public abstract AbstractBeginNode getPrimarySuccessor()

Primary successor of the control split. Data dependencies on the node have to be scheduled in the primary successor.

Returns:

the primary successor
