ABSTRACT:
A program transformation processing system comprises a syntax analyzing part receiving a source program for analyzing the syntax of the received source program and generating intermediate codes in a predetermined format, and an optimization processing part receiving the intermediate codes to perform a predetermined optimization processing for generating an object code having as small program size as possible and as short execution time as possible. The optimization processing part includes a candidate intermediate code selection part for selecting from the intermediate codes an optimization candidate intermediate code which meets with a predetermined selection condition and which has possibility of one being to be optimized, an optimized pattern extracting part for performing a searching using the candidate intermediate code as a starting point, to extract an optimized pattern which is a pattern of the intermediate codes to be optimized, and an optimized intermediate code outputting part for outputting an optimized intermediate code corresponding to the optimized pattern.
