Orchestra compiler code generation efficiency

	Hey hey everyone, I was wondering how well the Csound compiler can optimise code or how much this actually matters, since finally it's a question of how the Csound binary is optimised for the running system. Does it help to reorder expressions, use bit shift instead of multiplication by 2^x and the like? Can anyone enlighten me please? Thank you, any hint is much appreciated!

	There is basic constnt folding but you should remember that Csound works in floaing point so bit shift it slpw -- convert to integer, shift, convert bck so lots of actions. All operations are via sibroutine cll s well so this is not the usul C case/ On Fri, 12 Jun 2015, F.
