Method Detail

makeAccessor

Exp makeAccessor(TreeFactory tf,
                 HCodeElement source)

Return a Tree.Exp which can be used to address the contents of this Location for a fetch or set operation. For a global register, the returned value will typically be an instance of Tree.TEMP; for a memory location one would expect an instance of Tree.MEM. The accessor may return any valid fragment of Tree code, though. As Tree form may not reuse subtrees, a new Tree.Exp object should be returned every time this method is called.

The given TreeFactory is used to create the accessor fragment.
