Method Detail

isEmpty

public boolean isEmpty()

getLastLocationAccess

public MemoryKill getLastLocationAccess(org.graalvm.word.LocationIdentity locationIdentity)

Description copied from interface: MemoryMap

Gets the last node that (potentially) wrote to locationIdentity.

Specified by:

getLastLocationAccess in interface MemoryMap

getLocations

public Collection<org.graalvm.word.LocationIdentity> getLocations()

Description copied from interface: MemoryMap

Gets the location identities in the domain of this map.

Specified by:

getLocations in interface MemoryMap

toMap

public org.graalvm.collections.EconomicMap<org.graalvm.word.LocationIdentity,MemoryKill> toMap()

generate

public void generate(NodeLIRBuilderTool generator)

Specified by:

generate in interface LIRLowerable

getKilledLocationIdentity

public org.graalvm.word.LocationIdentity getKilledLocationIdentity()

Description copied from interface: SingleMemoryKill

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

Specified by:

getKilledLocationIdentity in interface SingleMemoryKill

Returns:

the identity of the location killed by this node.
