LLVM Clang 3.8 Compiler Performance Benchmarks

Not much difference with C-Ray.

With the OpenMP Smallpt test, Clang 3.8 appears to be handling that properly now with OpenMP across all of the available threads on this Intel Xeon E5 system.

In other common C/C++ benchmarks, there isn't much change in performance.

The Redis performance appears to regress slightly on Clang 3.8.

Apache also isn't at its best with Clang 3.8. Stay tuned for more Clang 3.8 compiler tests once its officially out to see if any of these regressions has been addressed, since this compiler testing did happen a few days ago. There will also be the Clang 3.8 vs. GCC 6 compiler benchmarks forthcoming on Phoronix. More of the LLVM Clang 3.6 vs. 3.7 vs. 3.8 SVN benchmarks can be found via this OpenBenchmarking.org result file.
