Phoronix: LLVM Clang 3.5 Brings Some Compiler Performance Improvements

If all goes well, LLVM 3.5 will be released today. While we have already delivered some LLVM/Clang benchmarks of the 3.5 SVN code, over the days ahead we will be delivering more benchmarks of the updated compiler stack -- including looking at its performance against the in-development GCC 5.0. For getting this latest series of compiler benchmarking at Phoronix started, here's some fresh numbers of LLVM Clang 3.4 compared to a recent release candidate of LLVM Clang 3.5.

I would not call disabling asserts "their optimized mode", but to each his own. Just make sure you do the same for gcc when you compare clang to it ("--enable-checking=no"). Still, disabling the asserts might lead to unexpected results in cases where it should have resulted in a compiler error, and doing so with a brand new release or even a pre-release is foolish.
