```
target triple = "arm64-apple-macosx"
define <2 x i128> @crash(<2 x i128> %a, <4 x i128> %b) {
%r = call <2 x i128> @llvm.vector.partial.reduce.add.v2i128.v4i128(<2 x i128> %a, <4 x i128> %b)
ret <2 x i128> %r
}
```
Running through `llc` results in
```
ScalarizeVectorResult #0: t79: v1i128 = partial_reduce_umla t72, t75, t77
LLVM ERROR: Do not know how to scalarize the result of this operator!
