Abstract

A language processing system comprises an instruction parsing portion parsing instruction statement contained in a source program written by a high-level language and an assembler language in admixing manner, a register information discriminating portion discriminating if the instruction statement parsed by the instruction parsing portion is a register information indicative of a register value corresponding to a register operating instruction described by the assembler language, an intermediate code generating portion for generating an intermediate code of the instruction statement, a register information storage portion for storing the register information discriminated by the register information discriminating portion, a code optimizing portion for performing optimization by deleting a register operating instruction with respect to the register operating instruction code in the intermediate code when the register value indicated therein is the same as a register value indicated by an immediately preceding register information or an immediately preceding register operating instruction code, and code generating portion for generating a machine language code from the intermediate code optimized through the code optimization and outputting an object code.
