; This test intends to check vector promotion for scalable vector. Current target lowering
; rejects scalable vector before reaching getConstantVector() in CodeGenPrepare. This test
; will assert once target lowering is ready, then we can bring in implementation for non-splat
; codepath for scalable vector.
