针对C语言的面向方面语言设计与实现

Design and Implementation of Aspect-Oriented Language for C Language

C语言是使用率仅次于Java的编程语言,在实时控制、嵌入式系统、硬件驱动等领域有着广泛的应用.发展自面向对象的面向方面编程(AOP)思想是对横切关注点的有效模块化方法,如何将AOP的概念引入到面向过程的C语言中,提高开发效率和代码复用率,是一个非常有实际意义的课题.针对该课题,本文设计并实现一种针对C的AOP语言MOVEC.分析了AOP的基本概念并将现有针对C的AOP语言进行了对比;设计了更加完善的针对C的AOP语言MOVEC;给出了基于开源编译器Clang和源代码插桩的M OVEC语言实现;通过实验从时间和空间效率上证明了M OVEC语言的可行性.

As the second important language, C is widely used in areas such as real-time control, embedded system, hardware driver and so on. Developed from OOP, aspect-oriented programming（ AOP ） is an effective modularization of cross-cutting concerns. How to introduce the AOP concept into the C language is a meaningful issue for software development and code reuse. This paper designs and implements an AOP language called MOVEC for C language. It analyzes the basic concepts of AOP and compares the existing AOP languages for C, designs a better AOP language called MOVEC for C,implements MOVEC based on Clang compiler and source code instrumentation, and finally proves its feasibility by experiments of time and space efficiency.
