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

The used machine is 3.0Ghz Intel Core2 with 4GB memory under Fedora Core8. The compilers are configured with --enable-checking=release.

All changes are given relative to LLVM-2.3.

We used -O0 for 176.gcc compilation by llvm-2.3 because 176.gcc crashes LLVM compiler in -O2 and -O3 mode.
