摘要： To monitor the execution path of executable code, only non-deterministic jump instructions of the executable code are instrumented by replacing them with respective recording instructions that record the results of executions of the non- deterministic jump instructions and then emulate those executions, thereby providing instrumented code, and the instrumented code is executed. Preferably, the recording instructions are one byte long and invoke an interrupt service routine that does the recording and the emulating. Optionally, selected instructions of the executable code are replaced with trigger instructions for turning the recording on and off. Preferably, after the instrumented code is executed, the addresses of the instrumented instructions and the results of their executions are played back either forward or backward. Optionally, the instrumented code is executed a second time and the results of the executions of the instrumented instructions in the two executions of the instrumented code are compared.
