Kamil Rytarowski 7160c2f770 Prevent Thread Exited/Joined events race 
Summary:
Add atomic verification to ensure that Thread is Joined after marking it
Finished.

It is required for NetBSD in order to prevent Thread Exited/Joined race,
that may occur when native system libpthread(3) cannot be reliably traced
in a way to guarantee that the mentioned events happen one after another.

This change fixes at least TSan and LSan on NetBSD.

clang Determine the attribute subject for diagnostics based on declarative information in DeclNodes.td. This greatly reduces the number of enumerated values used for more complex diagnostics; these are now only required when the "attribute only applies to" diagnostic needs to be generated manually as part of semantic processing. 2017-11-26 20:01:12 +00:00
