3 ; The DAGCombiner tries to do following shrink:
4 ; Convert x+y to (VT)((SmallVT)x+(SmallVT)y)
5 ; But currently it can't handle vector type and will trigger an assertion failure
6 ; when it tries to generate an add mixed using vector type and scalar type.
7 ; This test checks that such assertion failur should not happen.
