AMD Bulldozer Compiler Tests Testing GCC 4.6, GCC 4.7 snapshot, and Open64 4.2.4 compilers on an AMD FX-8150 Bulldozer CPU. Testing with stock compiler support and then when the CFLAGS/CXXFLAGS with having mtune/march options for Bulldozer (bdver1) set. For the GCC releases there's also -Ofast with the bdver1 tuning. Benchmarking by Michael Larabel for a future article on Phoronix.com.
