  /* VEX can sometimes generate code which returns to the dispatcher
     with the guest state pointer set to VEX_TRC_JMP_EMWARN or 
     VEX_TRC_JMP_EMFAIL.  This means that VEX is trying to tell Valgrind
     something noteworthy about emulation progress. For example, that Valgrind
     is doing imprecise emulation in some sense.  The guest's pseudo-register
     "guest_EMNOTE" will hold a value of type VexEmNote, which describes
     the nature of the warning.  Currently the limitations that are
     warned about apply primarily to floating point support.
  
     All guest states must have a 32-bit (UInt) guest_EMNOTE pseudo-
     register, that emulation warnings can be written in to.
  
     Note that guest_EMNOTE only carries a valid value at the jump
     marked as VEX_TRC_JMP_EMWARN / VEX_TRC_JMP_EMFAIL.  You can't assume
     it will continue to carry a valid value from any amount of time after
     the jump.
