/*
 * Summary: This macro is used to get Variable or internal type
 *   data (such as LoDTensor or SelectedRows) of the Input and
 *   Output in op, generally used when call scope.FindVar(Input/
 *   Output("Name")) or ctx.Input<LoDTensor>().
 *   Firstly this macro check whether the obtained pointer is null,
 *   and then return data if it is not null.
 *
 * Note: This macro is only suitable for specific scenarios and
 *   does not intended to be widely used. If it cannot meet the
 *   requirements, please use other PADDLE_ENFORCE** check macro.
 *
 * Parameters:
 *     __PTR: pointer
 *     __ROLE: (string), Input or Output
 *     __NAME: (string), Input or Output name
 *     __OP_TYPE: (string), the op type
 *  
 * Return: The data pointed to by the pointer.
 *
 * Examples:
 *    GET_DATA_SAFELY(ctx.Input<LoDTensor>("X"), "Input", "X", "Mul");

/*
 * Summary: This BOOST_GET(_**) series macros are used to call boost::get
 *   safely. boost::get is not a completely safe api, although it will not
 *   go wrong in most cases, but in extreme cases, it may fail and directly
 *   throw a boost::bad_get exception, without any stack information.
 *   This kind of problems is difficult to debug, so add these macros to
 *   enrich boost::get error information. At the same time, we restrict
 *   the direct use of boost::get by CI rule.
 *
 * Parameters:
 *     __TYPE: the target variable type
 *     __VALUE: the target variable to get
 *
 * Examples:
 *     - unsafe writing: int x = boost::get<int>(y);
 *     - safe writing: int x = BOOST_GET(int, y);
 *
 * Note: GCC 4.8 cannot select right overloaded function here, so need
 *    to define different functions and macros here, after we upgreade
 *    CI gcc version, we can only define one BOOST_GET macro.
