Wetrp: A Platform for Recording of Windows Program Execution Traces

Recording execution traces is emerging as a promising approach to overcome many of the obstacles in software debugging. Facing the shortages of current technologies in recording program execution traces, we present an instruction-level recording platform in Windows, which enables user to record instruction and data flows of program dynamically with full fidelity. The platform is embedded in the flexible software layer between applications and Windows OS. While implementing the platform, execution intercepting technology, transparency technology, code cache management policy and instruction subdividing technology are mainly used. To demonstrate the usefulness and effectiveness of our platform, we implement several recording tasks on benchmarks. Our recording overheads are quite reasonable as demonstrated by experimental data.
