Please don't wait months to ping on a patch; if you haven't gotten any response in a week, please ping, and if you haven't gotten any response in a couple weeks, please email llvmdev.  We want to review patches in a timely fashion, but sometimes reviewers miss an email, or incorrectly expect someone else will review the patch.

I just tried your testcase, and it looks like it passes without your patch.  What new cases does this patch handle?
