setBci

void setBci(int bci)

Description copied from interface: DeoptBciSupplier

Remember the byte code index (BCI) for code generation or lowering purposes. For example, nodes lowering to foreign calls that can safepoint require a valid BCI for computations of the during-state of such a foreign call.

Specified by:

setBci in interface DeoptBciSupplier

getDescriptor

ForeignCallDescriptor getDescriptor()

getKilledLocationIdentities

default org.graalvm.word.LocationIdentity[] getKilledLocationIdentities()

Description copied from interface: MultiMemoryKill

This method is used to determine which set of memory locations is killed by this node. Returning the special value LocationIdentity.any() will kill all memory locations.

Specified by:

getKilledLocationIdentities in interface MultiMemoryKill

Returns:

the identities of all locations killed by this node.

operands

default Value[] operands(NodeLIRBuilderTool gen)

computeStateDuring

default void computeStateDuring(FrameState currentStateAfter)

Description copied from interface: DeoptimizingNode.DeoptDuring

Compute the FrameState describing the program state during the execution of this node from an input FrameState describing the program state after finishing the execution of this node.

Specified by:

computeStateDuring in interface DeoptimizingNode.DeoptDuring

canDeoptimize

default boolean canDeoptimize()

Description copied from interface: DeoptimizingNode

Determines if this node needs deoptimization information.

Specified by:

canDeoptimize in interface DeoptimizingNode

isGuaranteedSafepoint

default boolean isGuaranteedSafepoint()

generate

default void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable
