Constructor Detail

ASET

public ASET(QuadFactory qf,
            HCodeElement source,
            Temp objectref,
            Temp index,
            Temp src,
            HClass type)

Creates an ASET object representing an array element assignment.

Parameters:

objectref - the Temp holding the array reference.

index - the Temp holding the index of the element to get.

src - the Temp holding the new value for the array element.

type - the component type of the referenced array.

Method Detail

objectref

public Temp objectref()

Returns the Temp with the array reference.

index

public Temp index()

Returns the Temp with the index of the element to get.

src

public Temp src()

Returns the Temp holding the new value for the array element.

type

public HClass type()

Returns the component type of the referenced array. All non-primitive types become Object.

use

public Temp[] use()

Returns all the Temps used by this quad.

Specified by:

use in interface UseDefable

Overrides:

use in class Quad

Returns:

the objectref, index, and src fields.

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 qqf,
                   TempMap defMap,
                   TempMap useMap)

Description copied from class: Quad
