Hi, During compilation gcc prints vectorization information to vect_dump file. Ex: fprintf (vect_dump, "vectorized %u loops in function.\n", num_vectorized_loops); I want to see that file. What is the option I have to give while compiling to get it? And to what file it is written? ___________________________________________________________ Yahoo! Answers - Got a question?
