Research on Decompiling Technology

Decompiling,as a means of analysing and understanding software,has great practical value.This paper presents a kind of ecompiling method offered by the anthors,in which the techniques of library-function pattern recognition,intermediate language, symbolic execution, rule-based data type recovery,program transformation,and knowl edge engineering are separately applied to different phases of decompiling.Then it is discussed that the techniques of developing expert systems are adopted to build a decompiling system shell independent of the knowledge of language and program running environment.The shell will become a real decompiler,as long as the new knowledge of application environment is interactively acquired.
