Bochs/bochs/cpu/resolve16.cc
Kevin Lawton 0cd7346b9c - Added an instruction cache. Size is fixed for the moment,
but if you hand edit cpu/cpu.h, and change BxICacheEntries,
  you can try different sizes.  I'll make this more flexible
  with configure.  For now, use "--enable-icache" with no parameters.

- Modified fetchdecode.cc/fetchdecode64.cc just enough so that
  instructions which encode a direct address now use a memory
  resolution function which just sticks the immediate address
  into rm_addr.  With cached instructions we need this.
