* An app which set XMM registers, calls DoNothing() which does nothing and then check that the XMM state haven't changed.
|
|
* A Pin tool that is being used together with this application probe DoNothing() and calls another function from that
|
|
* analysis function which scrambles XMMS registers (not the native application XMM registers). After that Pin_Detach() is being
|
|
* called from the same analysis function.
|
|
* Since analysis function shouldn't effect the state of the application then this function shouldn't change the native XMM
|
|
* registers when going to native after detach
