Unrelated to this thread, it would be great for this web page to get updated. You may find it to be "a better-supported point of view", but it is also comparing against clang 3.2, which is from the end of 2012, and a lot has changed since then. Modern clang versions have its autovectorizor on by default (like GCC's) and generate much better code in general. http://www.phoronix.com/ has done some benchmarks across a wider range of code than just spec (which is notoriously "hacked" by compiler developers) and Clang generates better code (and faster) than GCC in many cases. -Chris
