Ah, that would be wonderful :)

I'll definitely do that :)
I'm planning to run some of the other benchmarks we have here but I'm afraid I 
won't get to it until Friday. We have a few text decoding/manipulation 
benchmarks where GCC is generating suboptimal code (Visual C++ on identical 
machine manged to outperform it by almost two-fold) so I'm eager to see how 
LLVM stacks up. As soon as I have some results I'll post them here.
