I got it :)  It is 1st April.  At least we see that the processor does 
nothing.  You will never see it in modern x86 and x86_64 processors.  It 
is a black box (with their mysterious micro-ops which could be combined 
producing other mysterious things) resulting in try and pray 
optimization approach.
