FWIW, I just ported my ray tracer benchmark to C and found that llvm-gcc gives
much worse performance than gcc on x86

If anyone is motivated, please file bugs for the losing cases. Also,
it might make sense to incorporate the tests into our nightly tester

[LLVMdev] C++ ray tracer performance: gcc 4.3.2 vs llvm-gcc 4.2.1
On the off chance anyone here is interested in more performance results, I
compiled and ran the fastest of the implementations of the ray tracer in C++
from my language comparison:
http://www.ffconsultancy.com/languages/ray_tracer/
This is a small program with a relatively large hotpath. Specifically, around
30% of the time is spend in the ray sphere intersection but another 30% is
also spent in the intersect function that recursively traverses a
hierarchical scene.
This is on an (eight core) 2.1GHz Opteron 2352, compil...
