bcraig added a comment. Is there a benchmark where this demonstrates some performance improvement? I fear that the switch to condition_variable_any will swamp any performance gains from the switch to a spin lock.
Also, the spin lock is being held during allocating operations (the exception throws and at_thread_exit code). That's a little long to be holding a spin lock. https://reviews.llvm.org/D37677 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
