Class PrepareForCodeGen

java.lang.Object
jadx.core.dex.visitors.AbstractVisitor
jadx.core.dex.visitors.PrepareForCodeGen
All Implemented Interfaces:
IDexTreeVisitor
public class PrepareForCodeGen extends AbstractVisitor
Prepare instructions for code generation pass, most of this modification breaks register dependencies, so this pass must be just before CodeGen.
