  I am a wrapper around the Bochs C++ IA32 CPU emulator.  Note that currently I provide no access to the x87/mmx FPU state, only providing access to the SSE/xmm registers.
 
  Here is the configure script for the configuration this code assumes.  Offsets of fields will change with different configurations so they must agree.

  I am the superclass for the Simulation CPU instance wrappers. I ensure that methods used in both/all of them need not be copied.!

  I am a wrapper around the ARMulator CPU instance and emulator routines and I give access to disassembling using libopcodes. My C-part must be compiled with -DMODET, because otherwise my offsets are wrong by one field.!
