Constructor Details

StringLatin1InflateNode

 ValueNode dst,
 ValueNode len,
 jdk.vm.ci.meta.JavaKind writeKind)

StringLatin1InflateNode

public StringLatin1InflateNode(ValueNode src,
 ValueNode dst,
 ValueNode len)

Constructor for stub compilation. We set killedLocations to both char and byte array locations here, because we want to re-use the same stub for all call sites.

public StringLatin1InflateNode(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.
