; 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
