GCC 4.x Benchmarking - Intel, AMD 64-bit Benchmarking of GCC 4.2 through GCC 4.8 when building the compiler the same and setting CFLAGS/CXXFLAGS of -O3 and -march=native prior to test installation and execution. Benchmarking for a future article on Phoronix.com by Michael Larabel. Testing on an Intel Core i7 and AMD Opteron 2384 when using the 64-bit (x86_64 target) build of Ubuntu Linux.
