[Dave Green via Phabricator via llvm-commits]

Thanks. Is that with -mcpu=native or -mcpu=generic, and on which type of machine was it run? It sounds like the noise level is pretty high, which is a perpetual problem.

There are more accurate results in the .csv file that it generates - the results are not rounded to whole numbers so can be a little more accurate.
