METHOD FOR TRANSFORMING LOOP INCLUDING RECURSIVE ARITHMETIC INTO VECTOR

摘要

PURPOSE:To shorten executing time by selecting a code transformed into a vector in case it is decided in an executing mode that transformation into a vector is possible. CONSTITUTION:A vector compiler having a vector transformation system is stored in a main memory 1 and a central processing unit 3 carries out a vector transforming job. Thus a source program stored in a large-capacity storage device 5 is converted into an objective program and stored in a large-capacity storage device 6. Then the unit 3 produces an objective program including such a recursive arithmetic code than can select a vector code or a non-vector code after possibility for transformation into a vector is decided in an execution mode.
