Nonsense. As well as the builtins already mentioned, GCC has -ftree-vectorize which uses these SIMD instructions automatically when the compiler can deduce that the aliasing rules allow it. Dot product and matrix multiplication get a sizeable speed up when you use it. The 'restrict' keyword helps a lot, also
