Thanks, I think that's the problem. I can see the tablegen commands in #1341 but they aren't in #1331 or #1340.

I'll re-land this commit and we'll see if a clean build makes it work properly.

Thanks. My revert landed in http://lab.llvm.org:8011/builders/llvm-clang-x86_64-expensive-checks-win/builds/1340 <http://lab.llvm.org:8011/builders/llvm-clang-x86_64-expensive-checks-win/builds/1340> but it continued to fail so I was very confused.

Is forcing a clean build something I can do from the buildbot interface? I've got a few patches to commit that are likely to trigger this problem.

I had seen something similar before on MSVC so I tried fixing it in r300966 but with no luck. I then managed to reproduce it using an online MSVC compiler and fixed that issue in r300970 but still no luck. I'm going to revert the commit to make the bot green while I figure it out but I don't have a MSVC environment at the moment so I was wondering if anyone who does can reproduce the problem and tell me what it is that MSVC doesn't like.
