I think you should look into the tracing infrastructure that is gradually added to Qemu. I forgot the URL that provide the patch (since I am not sure whether it's fully merged with mainline). Please check this list archieve... NB: You're talking about qemu system emulation,right? not the user mode emulation, I assume? Because you said "executed in one step" (or something like that). AFAIK, although Qemu does lazy evalution, but for general registers it should be always updated. The one that gets lazy evalution for example is eflags. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
