; Make sure that the use of the IV outside of the loop (the store) uses the 
; post incremented value of the IV, not the preincremented value.  This 
; prevents the loop from having to keep the post and pre-incremented value
; around for the duration of the loop, adding a copy and an extra register
; to the loop.
