  peephole optimisation
  
     <compiler> A kind of code optimisation that considers only a
     few adjacent instructions at a time and looks for certain
     combinations which can be replaced with more efficient
     sequences.  E.g.
  
     	ADD R0, #1
     	ADD R0, #1
  
     (add one to register R0) could be replaced by
  
     	ADD R0, #2
