This is what I thought too, but I realized I had commented on the<br>
the actual commit: <a href="https://reviews.llvm.org/rL339367" rel="noreferrer" target="_blank">https://reviews.llvm.org/rL339367</a> and not<br>
the phabricator review: <a href="https://reviews.llvm.org/D50296" rel="noreferrer" target="_blank">https://reviews.llvm.org/D50296</a>. According<br>
to the phabricator review you did review the patch.<br></blockquote><div><br>Ah, indeed - just bad reading on my part. Sorry about that.<br><br>Tom - while the bug's being discussed/resolved, would you prefer this be reverted? I don't have a strong opinion either way really.<br> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
