Once upon a time we added some instruction counting and simple cache/tlb simulation to QEMU. You could take a look at git://brigitte.kvy.fi/git/qemu.git git://brigitte.kvy.fi/git/libqemu.git and compare the prof_qemu/* branches to origin/master. Unfortunately the changes are a bit old. -- Antti P Miettinen http://www.iki.fi/~ananaza/
