LANGUAGE PROCESSING SYSTEM WHICH GENERATES DEBUGGING SOURCE FILE CORRESPONDING TO OPTIMIZATION IMAGE AND METHOD THEREFOR

A language processing system including a parsing unit for receiving input of a source file to be processed and conducting parsing processing of the same, an optimization unit for receiving input of intermediate data generated by the parsing unit and conducting optimization processing of the same, a debugging source program information generating unit for generating a debugging source file which reflects the contents of optimization and whose form is approximate to a source file based on optimized intermediate data, and further, adding debug information obtained in the course of the generation of a debugging source file to optimized intermediate data, and a code generating unit for receiving input of intermediate data with debug information added and coding the same to generate an object file.
