Supporting classes

  • StaticInst - Used to hold static information and methods about specific binary instructions, such as addq's or subq's.
  • DynInst - Used to hold dynamic information about instructions in the pipeline, such as the PC or predicted target.
  • ThreadState - Used to store thread information that is generic across CPU models.
  • SimpleThread - Used by simple CPU models to store architected state and provide the ThreadContext interface.


  • ThreadContext - The ThreadContext class. Used to provide an interface for objects outside of the CPU to access the specific thread state.
  • ExecContext - The ExecContext interface. An implicit interface that is used by the ISA in order to access the CPU's architected state.
