@efriedma-quic @arsenm I do agree that this should not be needed and ideally the intrinsics should be covered in the standard GlobalISel flow, but we need those expanded prior to SPIRVEmitIntrinsics pass for special handling we have there for aggregates. Unfortunately, the problem is not as simple to solve, this patch simply extends the existing expansion we had for umul for the remaining operations.
