Method Detail

getLocationIdentity

public 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.

getSaveRegistersOp

generate

public void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable

uncommonTrap

public static Word uncommonTrap(long registerSaver,
                                int trapRequest)
