Detailed Description

template<class>
struct O3ThreadState< class >

Class that has various thread state, such as the status, the current instruction being processed, whether or not the thread has a trap pending or is being externally updated, the ThreadContext pointer, etc.

It also handles anything related to a specific thread's process, such as syscalls and checking valid addresses.
