    Phoronix: LLVM Clang 6.0 vs. 5.0 Compiler Performance On Intel/AMD Linux

    Since last week's big release of LLVM 6.0 along with Clang 6.0, I have been carrying out some fresh compiler benchmarks of the previous Clang 5.0 to this new stable release that switches to C++14 by default, among many other changes to LLVM itself and this C/C++ compiler front-end.

    Was there some separate shader compiler benchmark or didn't I just spot it from this?

      Compile times seem to be ~30% slower with Clang 6 compared to GCC 7.3 for me. Anyone noticed that? I switched to GCC again for development and only build with Clang to check from time to time.
