Functional description extraction of code based on formal semantics of Clight

Abstract

Code function description extraction is the basic premise of functional integration.To address the problem of common low accuracy rate of extraction of code function,the mechanism of extracting code function description based on formal semantic of Clight was proposed,and it was realized by algorithm of Clight code function description.This mechanism was strictly based on Clight natural semantics inference rules,ignoring the details of code execution in the middle,only concerned with the memory states before and after implementation.And as a functional description of the code feature description,it improved the accuracy of functional extraction and the success rate of the key area in software development.
