That fixes the test case you reduced for me. If you have any other regressions that point to palignr, I'd be especially interested to have an actual test case. As I noted in my commit log, there seems to be a clear place where using this could be faster but it introduces domain crossing. I don't really have a good model for the cost there and so am hesitant to go down that route without good evidence of the need.</div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Sep 17, 2014 at 1:30 PM, Chandler Carruth <span dir="ltr"><<a href="mailto:chandlerc@google.com" target="_blank">chandlerc@google.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><span class=""><br><div class="gmail_quote">On Wed, Sep 17, 2014 at 12:51 PM, Quentin Colombet <span dir="ltr"><<a href="mailto:qcolombet@apple.com" target="_blank">qcolombet@apple.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">We use two shuffles instead of 1 palign.</blockquote></div><br></span>Doh!
