; RUN: llc -march=arm64 < %s ; The DAGCombiner tries to do following shrink: ; Convert x+y to (VT)((SmallVT)x+(SmallVT)y) ; But currently it can't handle vector type and will trigger an assertion failure ; when it tries to generate an add mixed using vector type and scaler type. ; This test checks that such assertion failur should not happen. define <1 x i64> @dotest(<1 x i64> %in0) { entry: %0 = add <1 x i64> %in0, %in0 %vshl_n = shl <1 x i64> %0, <i64 32> %vsra_n = ashr <1 x i64> %vshl_n, <i64 32> ret <1 x i64> %vsra_n }
