Package proguard.dexfile.ir.ts

Class RemoveLocalFromSSA

  • All Implemented Interfaces:
    Transformer
    public class RemoveLocalFromSSA
extends StatedTransformer
    This class attempts to remove SSA form and reduce the number of variables used by the program. This is an optimiser which does not need to be used as it does not change the semantics of a program but simply the number of variables it uses and therefore its performance. However not using this will lead to much larger memory requirements of the other optimisers as it requires them to process more variables and variable assignments.
