; Revision 199135 introduced a wrong check in method
; DAGCombiner::SimplifyVBinOp in an attempt to refactor some code
; using the new method 'BuildVectorSDNode::isConstant' when possible.
;
; However the modified code in method SimplifyVBinOp now wrongly
; checks that the operands of a vector bin-op are both constants.
;
; With that wrong change, this test started failing because of a
; 'fatal error in the backend':
; Cannot select: 0x2e329d0: v4i32 = BUILD_VECTOR 0x2e2ea00, 0x2e2ea00, 0x2e2ea00, 0x2e2ea00
; 0x2e2ea00: i32 = Constant<1> [ID=4]
; 0x2e2ea00: i32 = Constant<1> [ID=4]
; 0x2e2ea00: i32 = Constant<1> [ID=4]
; 0x2e2ea00: i32 = Constant<1> [ID=4]
