GCC 6.2 vs. Clang 3.9 Compiler Performance On Clear Linux With Intel Kaby Lake

Clang 3.9 added in another win with the TSCP chess engine benchmark.

But GCC continues to do better with the Himeno pressure solver test.

It was a tight race with ebizzy.

While LLVM Clang once compiled code significantly faster than GCC, GCC has been working on improving its compilation times while we have seen Clang regress in recent releases as new functionality gets tacked on. At least for this Kaby Lake system on Clear Linux, GCC 6.2 is compiling code faster than Clang 3.9.
