GCC, LLVM/Clang 3.0, AMD Open64

Compiler performance benchmarking of GCC 4.6.2 RC, LLVM 3.0, and latest Open64 from AMD. All phoronix test suite benchmarks were built with CFLAGS/CXXFLAGS of -march=native and -mtune=native under each compiler. Tests by Michael Larabel for a future Phoronix.com article.

Compare your own system(s) to this result file with the Phoronix Test Suite by running the command: phoronix-test-suite benchmark 1110220-AR-OPENLLVM254
