[llvm-commits] [PATCH] Thread-safe ManagedStatic

[Owen Anderson]

So, now that we have the basic infrastructure more or less in place, here's another attempt at making a thread-safe version of ManagedStatic based on double-checked locking with explicit fences.  It also proved necessary to provide atomic update facilities for the global StaticList as well.

Please see the included block comment for more details on exactly what safety guarantees this code provides.
