[Bug c/29833] gcc 4.1.2 on x86_64 Ubuntu Edgy generates incorrect prefetch instruction

[rguenth at gcc dot gnu dot org]

------- Comment #2 from rguenth at gcc dot gnu dot org  2006-11-14 15:54 -------
What does adding '-v' to the compile command say?  It seems Ubuntu is using a
default -march that enables 3dnow (k8 or opteron maybe) - it should use x86_64
instead.
