<pre>Crashing should be fixed with:
<a href="https://reviews.llvm.org/rG8e34dd941cb3">https://reviews.llvm.org/rG8e34dd941cb3</a>
A couple of potential follow-ups:
1. There's an unfortunate overload of the word "simple" in LLVM that threw me
off for a second. We already have this check:
if (!Store->isSimple())
But that's about volatile/atomic. We also use "simple" for types meaning a type
"that is supported natively by some processor".
2. If performance matters for the source code in the description, that could be
a separate bug. We're transferring between scalar and vector registers, and
that seems unlikely to be optimal.</pre>
