Hi: I would like to evaluate translation overhead from application memory to shadow memory only. In another word, no overhead for checking and propagation. Is there any simple way to do it, e.g. an switch to turn on and off for it? Best Regards Qin |

Nothing quite that easy, but it might be possible with a few code modifications. I recommend reading http://www.valgrind.org/docs/shadow-memory2007.pdf, it has lots of details about Memcheck's shadow memory including code snippets. Nick |
