| Abstract(in English) | In code optimization techniques of compilers, many local and global optimization methods have been proposed so far, but few works for inter-procedural optimization have been made. In this paper we propose a new inter-procedural optimization technique which is cosidered as an extension of the induction variable optimization one for loop programs: we regard the repetitive behavior of self recursive procedures as a kind of loops, find out arguments behaving like induction variables, and optimize expressions with these arguments. First, the notion of quasi-induction variables which is an extension of induction variables is introduced, then a new inter-procedural optimization algorithm based on the notion is presended and the correctness proof is given. By applying this method to a quick-sort program, we obtained the result that the code is 10% faster than that generated by gcc. |
