Howard Hinnant ee7a0bf265 Andrew Morrow: Attached is a writeup of the current state of the libc++ test suite on Linux.

There are a few tests that are listed as failing here for which I have
a patch in the works. I'll be sending those along soon. There are
others where I know what is going on but don't yet have a solution,
and I've included some notes for those. Several still need to be
investigated, mostly in localization and the regex test suite. I think
that many of these failures are due to locale implementation
variations that make the expected test results not match the actual
results. I'm not sure what the best way to make the tests accomodate
this sort of variation might be.

The failures in the unique_ptr test suite are very new and are caused
by a clang crash which I've not yet looked into.

Implement [util.smartptr.shared.atomic]. This is the last unimplemented

lib

Allow libc++ to be built with CMake from within the LLVM tree. The libc++ part is just some renaming as the variable was already in use, conflicting with something else in the LLVM tree. Contributed by Ruben Van Boxem.

src

Despite my pathological distrust of spin locks, the number just don't lie. I've put a small spin in __sp_mut::lock() on std::mutex::try_lock(), which is testing quite well. In my experience, putting in a yield for every failed iteration is also a major performance booster. This change makes one of the performance tests I was using (a highly contended one) run about 20 times faster.
