I believe one of the reason the benchmark numbers are totally bogus is that the compilation are done on ARM hosts.
Given the benchmarks are apparently compiled without -mcpu=cortex-a9, I suspect LLVM ended up generating code for "generic" ARMv4 cpu.
This article makes me sick in my stomach.

The bench marking was still being done from a PandaBoard ES with Texas Instruments OMAP4460 dual-core ARM Cortex-A9 development board. Via the CFLAGS/CXXFLAGS, -march=armv7-a was passed to each compiler. "
On the other hand once you sort out your flags war and reach consensus it might be interesting to see this test run on a
Calxeda quad-core ARM Cortex-A9 processor optimized for using in Servers over 10Gigabit/s internal fabric on each card
sample box with 2 or more cards installed for 32 Cortex A9 cores/8 SOC and greater etc and you really should go and get the latest Linaro GCC etc too.
Hmm i cant seem to get in post video link working, odd.
