Bochs/bochs/cpu
History
Kevin Lawton 67721c48f4 The convience functions protected_mode(), v8086_mode() and real_mode() 
now simply return a cached value which is set upon mode changes.
  The biggest problem was protected_mode() which did something like:

    return CR0.PM && ! EFLAGS.VM

  This adds up when it was being executed many times in branch functions
  etc.  Now, cached values are set and sampled instead.
