question: public static int recompileWithOpt ( NormalMethod method ) { if ( VM . BuildForOptCompiler ) { CompilationPlan plan = new CompilationPlan ( method , ( OptimizationPlanElement [ ] ) optimizationPlan , null , ( OptOptions ) options ) ; return recompileWithOpt ( plan ) ; } else { if ( VM . VerifyAssertions ) VM . _assert ( VM . NOT_REACHED ) ; return - 1 ; } }
target:  A wrapper method for those callers who don't want to make optimization plans
