[Bug tree-optimization/34265] Missed optimizations

[rguenth at gcc dot gnu dot org]

------- Comment #4 from rguenth at gcc dot gnu dot org  2007-11-28 16:17 -------
I would in principle say no - we can instead improve the middle-end here.  But
it may pay off to not generate a loop for short vectors in case the resulting
IL is smaller for example.  Of course it would duplicate logic in the frontend
if that is not already available, so from a middle-end point of view we should
fix it there instead (the same problems happen for C and C++).  See PR34223.
