Sounds like the same performance win you get feeding a super scaler processor code ordered by a VLIW compiler. The super scaler design searches for parallelism among instructions at execution time, and being feed instuctions in a good ILP ordering by a VLIW compiler, of course it finds more. -- -- David (obrien@NUXI.ucdavis.edu -or- obrien@FreeBSD.org) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
