Pretty please? We now have a significant number of builders that test libc++. I really want those builders to be green.
Most of these failures are due to differences in locale data, including those in regex. I will continue working on fixing the locale and regex tests but there is no consensus on what the correct direction to go.
Since the builders display a list of XFAIL tests they are by no means hidden. It just means they are expected failures. Now unexpected failures won't get mixed in with well known and expected failures.
