Detailed Description

template<class TC>
class gem5::CheckerThreadContext< TC >

Derived ThreadContext class for use with the Checker.

The template parameter is the ThreadContext class used by the specific CPU being verified. This CheckerThreadContext is then used by the main CPU in place of its usual ThreadContext class. It handles updating the checker's state any time state is updated externally through the ThreadContext.
