Method Detail

getLocationIdentity

public jdk.internal.jvmci.meta.LocationIdentity getLocationIdentity()

Description copied from interface: MemoryCheckpoint.Single

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:

getLocationIdentity in interface MemoryCheckpoint.Single

Returns:

the identity of the location killed by this node.

generate

public void generate(NodeLIRBuilderTool generator)

Specified by:

generate in interface LIRLowerable
