------- Comment #7 from rguenth at gcc dot gnu dot org 2009-11-07 14:44 ------- Oh, there's no loop. Then it's the not implemented strength-reduction on scalar code that is the issue. In theory strength-reduction can be integrated into our global value-numbering / PRE code, but nobody has done that.
