Constructor Detail

SET

public SET(QuadFactory qf,
           HCodeElement source,
           HField field,
           Temp objectref,
           Temp src)

Creates a SET representing a field assignment operation.

Parameters:

field - the description of the field to set.

objectref - null for static fields, or a Temp referencing the object containing the field otherwise.

src - the Temp containing the value to put into the field.

Method Detail

field

public HField field()

Returns the description of the field to set.

objectref

public Temp objectref()

Returns null if the SET is on a static field, or the Temp containing the field to set otherwise.

src

public Temp src()

Returns the Temp containing the desired new value of the field.

use

public Temp[] use()

Returns the Temps used by this Quad.

Specified by:

use in interface UseDefable

Overrides:

use in class Quad

Returns:

the objectref 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,
