Detailed Description

template<class DynInstPtr>
class gem5::Checker< DynInstPtr >

Templated Checker class.

This Checker class is templated on the DynInstPtr of the instruction type that will be verified. Proper template instantiations of the Checker must be placed at the bottom of checker/cpu.cc.
