HCodeElement, CFGraphable<Quad,Edge>, UseDefable, Graph.Node<Quad,Edge>, Serializable, Cloneable, Comparable<Quad>

public class PMOFFSET
extends PCONST

PMOFFSET computes the POINTER offset needed to invoke a given virtual method. Non-virtual methods are invoked via the POINTER obtained from PMCONST.

Constructor Detail

PMOFFSET

public PMOFFSET(LowQuadFactory qf,
                HCodeElement source,
                Temp dst,
                HMethod method)

Creates a PMOFFSET representing the POINTER offset needed to invoke a given virtual method.

Parameters:

dst - the Temp in which to store the computed offset.

method - the HMethod whose offset to compute.

Method Detail

method

public HMethod method()

Returns the method whose offset is computed.

kind

public int kind()

Description copied from class: Quad

Return an integer enumeration of the kind of this Quad. The enumerated values are defined in QuadKind.

Specified by:

kind in class Quad

rename

public Quad rename(QuadFactory qf,
                   TempMap defMap,
                   TempMap useMap)

Description copied from class: Quad

Create a new Quad identical to the receiver, but with all Temps renamed according to a mapping. The new Quad will have no edges.

The new Quad will come from the specified QuadFactory.

Specified by:
