[LLVMdev] Help turn the vectorizer bot green

The vectorizer buildbot currently shows 4 miscompiles:


I had looked at the first one (oggenc) a couple of weeks ago, and because there is only one significant source file, it was straightforward to bugpoint the problem. It turns out that it was a codegen problem that had nothing to do with vectorization at all (see http://llvm.org/bugs/show_bug.cgi?id=14231)

I've yet to examine the others in detail, but I suspect CodeGen problems are likely as well. It would be nice to have a green vectorizer bot for 3.2, and I'd appreciate some help in tracking these down.

Thanks again,
