Vectorize multiple loop processing including aggregation operations. In the vector double loop processing, the loop length of the inner loop depends on the loop variable of the outer loop, and the first array representing the result of the double loop processing uses the loop variable of the inner loop as an index value. A detection unit 31 that detects a configuration that is not included, a fixed value determination unit 32 that determines a fixed value as the loop length of the inner loop when the configuration is detected, and a second that is used to calculate the value of the first array By expanding the array size of the array, an extension unit 33 that allows the double loop processing to process the inner loop whose loop length is the fixed value, and an element value for the element of the added second array By setting the extension element setting unit 34 so that the results of the double loop processing are equal before and after these processes are performed, and based on the processing results, It comprises an updating unit 35 for updating the Towea, the.
