The goal of these runs is to compare the performance of the latest versions of LLVM and GCC on x86_64. Most widely used common options -O2 and -O3 are taken for all runs.

The used machine is 2.93Ghz Intel Core I7 with 8GB memory under Fedora Core10.

GCC-4.5.0 is configured with --enable-checking=release and compiled by GCC-4.3.2. LLVM-2.7 x86_64 binaries are taken from LLVM download site. All changes are given relative to LLVM-2.7.
