Constructor Details

StringUTF16CompressNode

public StringUTF16CompressNode(ValueNode src,
 ValueNode dst,
 ValueNode len,
 jdk.vm.ci.meta.JavaKind readKind)

StringUTF16CompressNode

public StringUTF16CompressNode(ValueNode src,
 ValueNode dst,
 ValueNode len)

Constructor for stub compilation. We set locationIdentity to LocationIdentity.any() here, because we want to re-use the same stub for all call sites.

public StringUTF16CompressNode(ValueNode src,
 ValueNode dst,
 ValueNode len,
 EnumSet<?> runtimeCheckedCPUFeatures)

Method Details

getKilledLocationIdentities

public 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.

Returns:

the identities of all locations killed by this node.

getForeignCallDescriptor

public ForeignCallDescriptor getForeignCallDescriptor()

getForeignCallArguments

public ValueNode[] getForeignCallArguments()

emitIntrinsic

public void emitIntrinsic(NodeLIRBuilderTool gen)

Description copied from interface: IntrinsicMethodNodeInterface

Emit the method body.
