GCC 4.3 (auto-vectorizing gcc with openmp) :

Compiled using source code from the GNU CVS servers. This contains current versions of gfortran (GNU F95, this is a version of the much awaited, free, open source, F95 compiler), gcc (GNU C) and g++ (GNU C++) compilers that can perform auto-vectorization (i.e. modify code to take advantage of AltiVec/SSE, automatically). Use flag -O3 -ftree-vectorize to enable that option. For more information, see this webpage. Download my binaries, and cd to the download folder. Then gunzip gcc-bin.tar.gz (if your browser didn't do so already) and sudo tar -xvf gcc-bin.tar -C /. It installs everything in /usr/local. You invoke F95 by typing gfortran. You will also need to have Apple's Developer Tools installed. They are included on a separate CD in the retail version of OS X and also available as a free download from Apple's Developer Site. Please install the most current version of Developer Tools, version 2.4.1. Finally, note that there is an alternate g95 project, that is not part of GCC. They seem to have recently released their own official version of g95 for OS X which you may wish to try. Again, note that that g95 is not the same as this version here. Some reports suggest that this alternate g95 is ahead in the implementation of F95 features, but there are mixed reports regarding its optimization capabilities.
