<div dir="ltr">I recognize these failures, and I think they should be fixed when building with clang 3.8.

Hi Krzysztof,<br>
<br>
If I understand correctly you're building LLVM top-of-tree with 3.7.0?<br>
Or is this a bug in 3.7.0?<br>
<br>
What operating system are you on?<br>
<br>
Cheers,<br>
Lang.<br>
