Method Detail

getKilledLocationIdentity

public org.graalvm.word.LocationIdentity getKilledLocationIdentity()

Description copied from interface: SingleMemoryKill

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:

getKilledLocationIdentity in interface SingleMemoryKill

Returns:

the identity of the location killed by this node.

hasSideEffect

public boolean hasSideEffect()

An exception handler is an entry point to a method from the runtime and so represents an instruction that cannot be re-executed. It therefore needs a frame state.

Specified by:

hasSideEffect in interface StateSplit

Overrides:

hasSideEffect in class BeginStateSplitNode

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

verify

public boolean verify()

Overrides:

verify in class AbstractBeginNode
