In supercollider. > In any case, perhaps the solution is to disable supernova in ppc64el > as well instead of adding custom flags. Simply disabling it for ppc64el did not do the work (completely), but you can test it if you want =) I think Konstantinos would be able to give you more accurate answers to your questions regarding altivec and simd in general. He knows a lot of that stuff. He is cc'ed (markos). Thanks!
