Retpoline fix? #12

Open zwimer opened 6 years ago

zwimer commented 6 years ago

After spectre and meltdown, the retpoline fix was released. Intel CET does not play well with it, can an exception to the shadow stack be made to handle this?

This can be done by ignoring the next ret when the instructions push and ret are found in that order.
