We generated the IR modules for our experiments with clang, starting from the C version of the shootout suite. No LLVM optimization passes were performed on the code other than {\em mem2reg}, which promotes memory references to be register references and is typically used in SSA form construction.  Experiments were performed on an octa-core 2.3 Ghz Intel Xeon E5-4610 v2 with 256+256KB of L1 cache, 2MB of L2 cache, 16MB of shared L3 cache and 128 GB of DDR3 main memory, running Debian Wheezy 7, Linux kernel 3.2.0, LLVM 3.6.2 (Release build, compiled using gcc 4.7.2), 64 bit.  For each benchmark we performed 10 trials preceded by an initial warm-up iteration; reported confidence intervals are stated at $95%$ confidence level.  \subsection{Results}  \begin{itemize}
