摘要: This paper presents a new approach to dependence testing in the presence of nonlinear and non-closed array index expressions pointer references. The chains recurrences formalism algebra is used analyze recurrence relations induction variables, for constructing forms We use these determine if references are free dependences loop nest. Our formulation enhances accuracy standard algorithms such as extreme value test range test. Because easily converted closed (when they exist), variable substitution recovery can be delayed until after analyzed
