------- Comment #6 from rguenth at gcc dot gnu dot org 2008-08-18 15:20 ------- The problem for the GCC vectorizer is that there are no loads or stores left in the loop and it doesn't handle vectorizing "registers" only. This is a case where real vectorization of straight-line code would be necessary.
