Method Detail

lower

public void lower(LoweringTool tool)

Description copied from interface: Lowerable

Expand this node into lower level nodes expressing the same semantics. If the introduced nodes are themselves lowerable, they should be recursively lowered as part of this call.

Specified by:

lower in interface Lowerable

getLocationIdentity

public org.graalvm.word.LocationIdentity getLocationIdentity()

Specified by:

getLocationIdentity in interface MemoryAccess

canFloat

public boolean canFloat()

Description copied from interface: FloatableThreadLocalAccess

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.

Specified by:

canFloat in interface FloatableThreadLocalAccess
