GCC 4.7.0 was faster than LLVM/Clang 3.1 and Open64 4.5.1 for the GraphicsMagick Blur test. LLVM/Clang still does not support OpenMP, which is largely why the LLVM/Clang-produced binaries are much slower than GCC. However, the only compiler that also benefited in this test from targeting "bdver1" rather than "k8" was also the GCC 4.7.0 release.

The other GraphicsMagick tests also produced similar results to the blur test.
