Method Detail

hasSideEffect

public boolean hasSideEffect()

Description copied from interface: StateSplit

Determines if this node has a side-effect. Such nodes cannot be safely re-executed because they modify state which is visible to other threads or modify state beyond what is captured in FrameState nodes.

Specified by:

hasSideEffect in interface StateSplit

Overrides:

hasSideEffect in class AbstractStateSplit

getDescriptor

public ForeignCallDescriptor getDescriptor()

getLocationIdentities

public LocationIdentity[] getLocationIdentities()

Description copied from interface: MemoryCheckpoint.Multi

This method is used to determine which set of memory locations is killed by this node. Returning the special value LocationIdentity.any() will kill all memory locations.

Specified by:

getLocationIdentities in interface MemoryCheckpoint.Multi

Returns:

the identities of all locations killed by this node.

operands

protected Value[] operands(NodeLIRBuilderTool gen)

generate

public void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable

setStateAfter

public void setStateAfter(FrameState x)

Description copied from interface: StateSplit

Sets the FrameState corresponding to the state of the JVM after execution of this node.

Specified by:

setStateAfter in interface StateSplit

Overrides:

setStateAfter in class AbstractStateSplit

stateDuring

public FrameState stateDuring()

Specified by:

stateDuring in interface DeoptimizingNode.DeoptDuring

setStateDuring

public void setStateDuring(FrameState stateDuring)

Description copied from interface: DeoptimizingNode.DeoptDuring

Sets the FrameState describing the program state during the execution of this node.

Specified by:

setStateDuring in interface DeoptimizingNode.DeoptDuring

setBci

public void setBci(int bci)

Set the bci of the invoke bytecode for use when converting a stateAfter into a stateDuring.

computeStateDuring

public void computeStateDuring(FrameState currentStateAfter)

Description copied from interface: DeoptimizingNode.DeoptDuring

Compute the FrameState describing the program state during the execution of this node from an input FrameState describing the program state after finishing the execution of this node.

Specified by:

computeStateDuring in interface DeoptimizingNode.DeoptDuring

toString

public String toString(Verbosity verbosity)

Description copied from class: Node

Creates a String representation for this node with a given Verbosity.

Overrides:

toString in class Node

canDeoptimize

public boolean canDeoptimize()

Description copied from interface: DeoptimizingNode

Determines if this node needs deoptimization information.

Specified by:

canDeoptimize in interface DeoptimizingNode
