public interface FloatableThreadLocalAccess
extends FixedNodeInterface

Marker interface for fixed high-tier nodes involved in access to thread local variables. Nodes can implement this interface to signal that the VM-specific access to thread local information can be lowered to standard read nodes which may become floating.

Method Detail

canFloat

boolean canFloat()

Determine whether this node will float after high tier lowering and floating reads. It is the caller's responsibility to check whether floating reads are enabled at all.
