Detailed Description

template<class Impl>
class O3ThreadContext< Impl >

Derived ThreadContext class for use with the O3CPU.

It provides the interface for any external objects to access a single thread's state and some general CPU state. Any time external objects try to update state through this interface, the CPU will create an event to squash all in-flight instructions in order to ensure state is maintained correctly. It must be defined specifically for the O3CPU because not all architectural state is located within the O3ThreadState (such as the commit PC, and registers), and specific actions must be taken when using this interface (such as squashing all in-flight instructions when doing a write to this interface).
