Constructor Detail

DefaultSimplifierTool

public DefaultSimplifierTool(MetaAccessProvider metaAccess,
                             ConstantReflectionProvider constantReflection,
                             boolean canonicalizeReads)

Method Detail

getMetaAccess

public MetaAccessProvider getMetaAccess()

Specified by:

getMetaAccess in interface CanonicalizerTool

getConstantReflection

public ConstantReflectionProvider getConstantReflection()

Specified by:

getConstantReflection in interface CanonicalizerTool

canonicalizeReads

public boolean canonicalizeReads()

Specified by:

canonicalizeReads in interface CanonicalizerTool

allUsagesAvailable

public boolean allUsagesAvailable()

Description copied from interface: CanonicalizerTool

If this method returns false, not all usages of a node are yet available. So a node must not be canonicalized base on, e.g., information returned from Node.hasNoUsages().

Specified by:

allUsagesAvailable in interface CanonicalizerTool

deleteBranch

public void deleteBranch(Node branch)

Specified by:

deleteBranch in interface SimplifierTool

removeIfUnused

public void removeIfUnused(Node node)

Specified by:

removeIfUnused in interface SimplifierTool

addToWorkList

public void addToWorkList(Node node)

Description copied from interface: SimplifierTool

Adds a node to the worklist independent of whether it has already been on the worklist.

Specified by:

addToWorkList in interface SimplifierTool

addToWorkList

public void addToWorkList(Iterable<? extends Node> nodes)
