<div dir="ltr">(In addition to rnk's question: We build with -Werror, but Wliblto seems unaffected by this. Because of that, our bots didn't catch the new warning and we only noticed this when a human did a local build after we updated compilers and saw a wall of warnings. It'd be good if Wliblto was affected by -Werror too.)</div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Nov 21, 2016 at 4:18 PM, Reid Kleckner via cfe-commits <span dir="ltr"><<a href="mailto:cfe-commits@lists.llvm.org" target="_blank">cfe-commits@lists.llvm.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">rnk added a comment.<br>

This added a bunch of warnings to the Chromium build, which doesn't use LTO today, so we had to revert our clang roll:<br>

<br>
We currently don't use LTO on Mac, so we don't build or package the LTO plugin, and in the near term aren't planning to change that. For now, we really want the previous behavior: if the linker encounters a .bc file, it should error. How can we get that behavior today?<br>
