Vectorization device, vectorization method, and recording medium on which vectorization program is stored

摘要

Provided is a vectorization device 30 comprising: a unit 31 that detects a configuration in which the inner loop length depends on the outer loop variable, and in which a first array indicating the results of dual-loop processing does not contain the inner loop variable as an index value; an unit 32 that, when the configuration is detected, determines a fixed value as the inner loop length; an unit 33 that expands the array size of a second array used in the calculation of the first array value, and thereby enables dual-loop processing of the inner loop; an unit 34 that sets an element value for an added element of the second array, and thereby, before and after such processing is carried out, enables the results of the dual-loop processing to be made equal; and an unit 35 that updates the software on the basis of such processing results.
