The Research & Implementation of Code Automatic Instrumentation Technology

This paper introduces the background of code instrumentation technology and gives a brief comparison between manual and automatic instrumentation at first. Then the paper puts the focus on the analysis and comparison of the feasibility and solution of implementing code instrumentation in different compiling phases. One CPU-independent syntax and lexical analysis phase with code instrumentation function based on the preprocessed file inserted between preprocessing and compiling phase is proposed and the implementation of one simple prototype is provided at last.
