Friendly ping.<br>
<br>
Is there something left to improve in this patch? I'm asking this because a fix for <a href="https://bugs.llvm.org/show_bug.cgi?id=46940" rel="noreferrer" target="_blank">https://bugs.llvm.org/show_bug.cgi?id=46940</a> builds on this fix, so I'd like to see this patch checked in if there is no pending issues. Thanks!<br>
