Method Detail

register

public static void register(Architecture architecture,
                            InvocationPlugins plugins,
                            Replacements replacements)

arrayUtilsIndexOf

public static boolean arrayUtilsIndexOf(GraphBuilderContext b,
                                        JavaKind arrayKind,
                                        JavaKind stride,
                                        boolean findTwoConsecutive,
                                        boolean withMask,
                                        ValueNode array,
                                        ValueNode fromIndex,
                                        ValueNode maxIndex,
                                        ValueNode... values)

toByteOffset

public static ValueNode toByteOffset(MetaAccessProvider metaAccess,
                                     GraphBuilderContext graph,
                                     ValueNode offset,
                                     JavaKind stride)

constantStrideParam

public static JavaKind constantStrideParam(ValueNode param)

constantBooleanParam

public static boolean constantBooleanParam(ValueNode param)

inferLocationIdentity

public static org.graalvm.word.LocationIdentity inferLocationIdentity(ValueNode isNativeA,
                                                                      ValueNode isNativeB,
                                                                      boolean nativeToAny)

Infer the location identity of two TruffleString data pointers from boolean parameters isNativeA and isNativeB. If both parameters are constant and true, the resulting locationIdentity is NamedLocationIdentity.OFF_HEAP_LOCATION, except when nativeToAny is true: in that case, the result is LocationIdentity.any(). This is used for methods with an additional java array parameter that is never native. If both isNativeA and isNativeB are constant and false, the result is getArrayLocation(JavaKind.Byte). Otherwise, the result is LocationIdentity.any().

applyIndexOf

public static boolean applyIndexOf(GraphBuilderContext b,
                                   boolean findTwoConsecutive,
                                   boolean withMask,
                                   ValueNode array,
                                   ValueNode offset,
                                   ValueNode length,
                                   ValueNode stride,
                                   ValueNode isNative,
                                   ValueNode fromIndex,
                                   ValueNode... values)
