--- Comment #1 from Sanjay Patel <spatel+llvm at rotateright.com> ---
I stumbled into FP undef again recently (without finding the above threads or
this bug):

http://lists.llvm.org/pipermail/llvm-dev/2018-February/121444.html
http://lists.llvm.org/pipermail/llvm-dev/2018-March/121481.html

And I'm fixing the LangRef and code based on that thread:

https://reviews.llvm.org/D44258
https://reviews.llvm.org/D44216
https://reviews.llvm.org/D44308
https://reviews.llvm.org/D44318

This particular example should be fixed with:
https://reviews.llvm.org/rL327138 (LangRef)
https://reviews.llvm.org/rL327212
