Hi Tim,

I'm not sure yet, but this one looks yours:

http://lab.llvm.org:8011/builders/clang-cmake-aarch64-full/builds/421

ExpandIntegerOperand Op #0: t143: f128 = select t142, t159, t8

It went away on the next build, but came back on 428, so that's why
I'm not sure.

I'll bisect, but if you can have a look form your side, I appreciate the help.

cheers,
