Even though my code has much improved abilities to resolve jump tables, it causes very large overhead compared to the Dyninst version you have. The time needed to parse a binary is almost doubled... I am optimizing this code. On the other hand, if you think the parsing overhead is bearable, I can create a new branch for you to get my current code. Let me know your opinion. Thanks --Xiaozhu
