Method Detail

getPrimarySuccessor

public AbstractBeginNode getPrimarySuccessor()

Description copied from class: ControlSplitNode

Primary successor of the control split. Data dependencies on the node have to be scheduled in the primary successor. Returns null if data dependencies are not expected.

Specified by:

getPrimarySuccessor in class ControlSplitNode

Returns:

the primary successor

probability

public double probability(AbstractBeginNode successor)

Specified by:

probability in class ControlSplitNode

setProbability

public boolean setProbability(AbstractBeginNode successor,
                              ProfileData.BranchProbabilityData profileData)

Description copied from class: ControlSplitNode

Attempts to set the probability for the given successor to the passed value (which has to be in the range of 0.0 and 1.0). Returns whether setting the probability was successful. When successful, sets the source of the knowledge about probabilities according to the profileData's profile source.

Specified by:

setProbability in class ControlSplitNode

getProfileData

public ProfileData.BranchProbabilityData getProfileData()

Description copied from class: ControlSplitNode

Returns the source of this node's knowledge about its successor probabilities.

Specified by:

getProfileData in class ControlSplitNode

getNext

public AbstractBeginNode getNext()

getOverflowSuccessor

public AbstractBeginNode getOverflowSuccessor()

setNext

public void setNext(AbstractBeginNode next)

generate

public void generate(NodeLIRBuilderTool generator)

Specified by:

generate in interface LIRLowerable

generateArithmetic

protected abstract Value generateArithmetic(NodeLIRBuilderTool generator)

getSuccessorCount

public int getSuccessorCount()

Description copied from class: ControlSplitNode

Returns the number of successors.

Specified by:

getSuccessorCount in class ControlSplitNode
