reason

public DeoptimizationReason reason()

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

getDebugId

public int getDebugId()

generate

public void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable

getActionAndReason

public ValueNode getActionAndReason(MetaAccessProvider metaAccess)

Specified by:

getActionAndReason in class AbstractDeoptimizeNode

getSpeculation

public ValueNode getSpeculation(MetaAccessProvider metaAccess)

Specified by:

getSpeculation in class AbstractDeoptimizeNode

getSpeculation

public JavaConstant getSpeculation()

deopt

public static void deopt(DeoptimizationAction action,
                         DeoptimizationReason reason)
