Method Detail

assertKind

public static ValueNode assertKind(Kind kind,
                                   ValueNode x)

shouldNotReachHere

public static RuntimeException shouldNotReachHere(String msg)

shouldNotReachHere

public static RuntimeException shouldNotReachHere()

assertLong

public static ValueNode assertLong(ValueNode x)

assertInt

public static ValueNode assertInt(ValueNode x)

assertFloat

public static ValueNode assertFloat(ValueNode x)

assertObject

public static ValueNode assertObject(ValueNode x)

assertDouble

public static ValueNode assertDouble(ValueNode x)

assertHigh

public static void assertHigh(ValueNode x)

filter

public static <T extends Node> Collection<T> filter(Iterable<Node> nodes,
                                                    Class<T> clazz)

valueString

public static String valueString(ValueNode value)

Converts a given instruction to a value string. The representation of an node as a value is formed by concatenating the character denoting its kind and its id. For example, "i13".

Parameters:

value - the instruction to convert to a value string. If value == null, then "-" is returned.

Returns:

the instruction representation as a string

asNode

public static ValueNode asNode(MemoryNode node)
