CheckerCPU class.
Dynamically verifies instructions as they are completed by making sure that the instruction and its results match the independent execution of the benchmark inside the checker. The checker verifies instructions in order, regardless of the order in which instructions complete. There are certain results that can not be verified, specifically the result of a store conditional or the values of uncached accesses. In these cases, and with instructions marked as "IsUnverifiable", the checker assumes that the value from the main CPU's execution is correct and simply copies that value. It provides a CheckerThreadContext (see checker/thread_context.hh) that provides hooks for updating the Checker's state through any ThreadContext accesses. This allows the checker to be able to correctly verify instructions, even with external accesses to the ThreadContext that change state.
