I agree that the compiler needs help from time to time, especially in C/C++ because of pointer aliasing. But Intel compilers do a lot with automatic vectorization. Since you look french, here is a video I have done for Intel showing the optimization of a code that relies completely on automatic vectorization : https://www.youtube.com/watch?v=pJbo6Z4NrgM&feature=youtu.be .
