Great thanks! I think you are right. We might kill the JIT perfomance by introducing such work. Another possible solution is we could do it at module level.
Is there a function smilar as " PyMODINIT_FUNC()" in Pypy? Here is the plan: 1. When the code try to import an external module, we invoke an inserted function doLog(). 2. doLog() function record the module name and all module's public function. In this way, I think we could greatly reduce the perfomance overhead.
