LLVM Clang 3.1 GCC 4.7 Intel Core i7 Benchmarks Benchmarking of GCC 4.6.3, GCC 4.7.0, LLVM Clang 3.0, and LLVM Clang 3.1 SVN compilers for a future article on Phoronix.com. Compilers built all test binaries with CFLAGS/CXXFLAGS of -O3 -march=native from this Intel Core i7 Clarksfield notebook. Ubuntu 12.04 LTS x86_64 was used with the Linux 3.2 kernel.
