Hi all, I run a build bot which updates and builds trunk llvm on a variety of OSes once every four hours. The windows build has been broken since r246156: http://104.154.46.123:8010/builders/win-64-trunk. A full clean didn't seem to fix it. Neither did several more recent updates (I'm currently building at 246208). The specific error is at the end of this log: http://104.154.46.123:8010/builders/win-64-trunk/builds/75/steps/Build%20LLVM%20...
