Thanks for commenting. I feel like I have to justify why I don't want to use
QEMU, which is fine since my choice is not frozen actually.
QEMU is much more than what I need for dynamically instrumenting software.
My goal is automated testing to find bugs, which can quickly be intensive in
term of computational load. Thus I am trying to get the smallest (and
Even using QEMU, I am not sure the piece of code already exists. And if it
does, I can still extract it and put where I want. My question is really :
is it a long work (several months) or is it just a matter of two weeks? And
if it does not already exists, could it mean it is a nonsense, then why?
Finally about your proposition using valgrind, I think I will stick to
windows tools because this is what I know better. But it was ironic, wasn't
