[API] Does the tvm has use-def chain?

I take a look at the function StmtSimplifier::VisitStmt_ in simplify.cc, it don’t use an api similar to getUser in llvm to get the user op of store op. so my question: Is there similar api in tvm to get the def-use chain ?

// eliminate useless stores
Stmt StmtSimplifier::VisitStmt_(const StoreNode* op) {
  Stmt stmt = Parent::VisitStmt_(op);
  op = stmt.as<StoreNode>();
  if (const LoadNode* load = op->value.as<LoadNode>()) {
    if (load->buffer_var.same_as(op->buffer_var) && ExprDeepEqual()(load->index, op->index)) {
      return Evaluate(0);
    }
  }
  return GetRef<Stmt>(op);
}
