* [https://locklessinc.com/articles/vectorize/ Auto-vectorization with GCC 4.7] - Although based on an earlier version of GCC, (and a number of new features have been added to the GCC autovectorizer since this article was written), it discusses some of the techniques and code adjustments that may be required to get the GCC compiler to vectorize code. Note that the <code>-fopt-info-vec-all</code> or <code>-fopt-info-vec-missed</code> options are useful in conjunction with this technique, as they will cause the compiler to emit information about the vectorization decisions that it is making.
