[Bug tree-optimization/42652] vectorizer created unaligned vector insns

[irar at il dot ibm dot com]

------- Comment #17 from irar at il dot ibm dot com  2010-02-22 09:01 -------
Is there a way to pass alignment information similar to PR 39954?

Otherwise, a proper fix would be some inter-procedural analysis... Meantime, we
can do intra-procedural analysis and fail when we reach function argument, i.e,
use runtime checks. We already have several types of versioning, so adding
another one will complicate the things even more, and will not always be
possible (because of code size constrains). 

Thanks,
Ira
