-maltivec allows acces to the Altivec ABI. But gcc cannot perform auto-vectorization on its own (yet). So compiling -maltivec won't change anything if the code does not contain Altivec instructions (in the form of assembly instructions or their C versions). And in that case, it would not even compile without -maltivec :) Guillaume. -- Guillaume Morin <[EMAIL PROTECTED]> Emacs, not just a way of life but a complete waste of disk space (Alan Cox)
