Method Detail

simplify

public void simplify(SimplifierTool tool)

Description copied from class: Node

Must be overridden by subclasses that implement Simplifiable. The implementation in Node exists to obviate the need to cast a node before invoking Simplifiable.simplify(SimplifierTool).

Specified by:

simplify in interface Simplifiable

Overrides:

simplify in class AbstractFixedGuardNode

lower

public void lower(LoweringTool tool)

Description copied from interface: Lowerable

Expand this node into lower level nodes expressing the same semantics. If the introduced nodes are themselves lowerable, they should be recursively lowered as part of this call.

Specified by:

lower in interface Lowerable

canDeoptimize

public boolean canDeoptimize()

Description copied from interface: DeoptimizingNode

Determines if this node needs deoptimization information.

Specified by:

canDeoptimize in interface DeoptimizingNode

Overrides:

canDeoptimize in class AbstractFixedGuardNode
