Method Detail

hasSideEffect

public boolean hasSideEffect()

Description copied from interface: StateSplit

Determines if this node has a side-effect. Such nodes cannot be safely re-executed because they modify state which is visible to other threads or modify state beyond what is captured in FrameState nodes.

Specified by:

hasSideEffect in interface StateSplit

Overrides:

hasSideEffect in class AbstractStateSplit

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.

generate

public void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable

endLockScope

public static void endLockScope()
