Bitcode file demonstrating bug
Enclosed is some bitcode that was generated using vector types. Building with
llc --mtriple=wasm32-unknown--wasm -mattr=simd128 < /tmp/mod.bc
works fine; building without simd128 like so:
llc --mtriple=wasm32-unknown--wasm < /tmp/mod.bc
fails with
ScalarizeVectorResult #0: t104: v1i8 = abs t97
LLVM ERROR: Do not know how to scalarize the result of this operator!</pre>
