GCC vs. LLVM-GCC Benchmarks

The chess performance with TSCP also dropped with the LLVM-GCC binary.

With the Tachyon ray-tracing engine, this was yet another area where LLVM-GCC was slower than the standalone GCC compiler.

Ending out our 12 LLVM tests, there is a second win for LLVM-GCC. With the C-Ray ray-tracing engine, the GCC-LLVM compiler produced a C-Ray binary was a few percentage points faster than one made by GCC. LLVM-GCC certainly has a ways to go to compete with GCC when it comes to the performance, but next up we will be testing LLVM/Clang to see how that performs.
