The source from this directory was copied from the PerformanceTests/StyleBench directory of the Webkit repository at: https://github.com/WebKit/WebKit/ The git commit used was: aac8c557da9ae65151ba533ba8d5b1c7841e741c The contents of this directory are intended for use to "train" the profile guided optimization (PGO) of Firefox and for benchmarking scenarios. The files inside this directory are not intended to ship with Firefox or any other product. If files inside this directory are useful for other purposes (e.g. JavaScript libraries), consumers should vendor those files separately, as it is not appropriate to pull in components of StyleBench for use outside of StyleBench.
