That's a good question, one that may be found our by adding it to just before the loop vectoriser and see how compile time increases proportional to the run-time performance benefits of standard benchmarks.

I'm adding some more people to chime in, just in case they have seen this before and have a plan we're not aware of. :)

cheers,
