| dc.description.abstract | This paper presents a technique for dependence analysis on programs with pointers or dynamic recursive data structures. It differs from previously proposed approaches in analyzing structure access conflicts between traversal patterns before gathering alias and connection information. Conflict analysis is conducted under the assumption that each unique path leads to a distinct storage location, and hence traversal patterns can be analytically compared to identify possible conflicts. The rationale of this assumption is that if statements are deemed to be dependent by this approach, they are inherently sequential regardless of the shapes of the data structures they traverse. Consequently, there is no need to perform alias/connection analysis on the statements that construct such data structures. Furthermore, the information of traversal patterns gathered in conflict analysis phase can direct alias/connection analysis algorithm to focus on statements that are crucial to optimizations or parallelization. A such {\em traversal-pattern-sensitive} pointer analysis algorithm will also be presented. | en_US |
