* Add the ShadowCallStack passVlad Tsyrklevich2018-04-041-0/+325
Summary: The ShadowCallStack pass instruments functions marked with the shadowcallstack attribute. The instrumented prolog saves the return address to [gs:offset] where offset is stored and updated in [gs:0]. The instrumented epilog loads/updates the return address from [gs:0] and checks that it matches the return address on the stack before returning.
