--- Comment #42 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-12-05 10:19:11 UTC --- Argh. It seems LIM didn't get proper lifting both at tuplification and alias-improvements time. So it's memory handling (everything it does with VOPs) is a little very much conservative (read: it doesn't really work). I'll look into this.
