I'd like to collect the raw instruction flow in simulation state(non realtime). LTT(Linux Trace Toolkit) is a good tool, but I want more detailing tracing info. I tried UML, it doesn't work well on PowerPC so far. Is it possible at all? Thanks __________________________________________________ Do You Yahoo!? Yahoo!
