在hk32f030m_gpio.h中:
typedef struct
{
  uint32_t GPIO_Pin;             /*!< Specifies the GPIO pins to be configured.
                                    This parameter can be any value of @ref GPIO_pins_define */

  GPIOMode_TypeDef GPIO_Mode;    /*!< Specifies the operating mode for the selected pins.
                                    This parameter can be a value of @ref GPIOMode_TypeDef */

  GPIOSpeed_TypeDef GPIO_Speed; /*!< Specifies the speed for the selected pins.
                                    This parameter can be a value of @ref GPIOSpeed_TypeDef  */

  GPIOOType_TypeDef GPIO_OType; /*!< Specifies the operating output type for the selected pins.
                                    This parameter can be a value of @ref GPIOOType_TypeDef  */

  GPIOPuPd_TypeDef GPIO_PuPd;    /*!< Specifies the operating Pull-up/Pull down for the selected pins.
                                    This parameter can be a value of @ref GPIOPuPd_TypeDef */

  GPIOSchmit_TypeDef  GPIO_Schmit; /*!<GPIO Schmitt>*/

}GPIO_InitTypeDef;

在编译的时候提示如下:
../../HK32F030M/HK32F030M_Lib/inc\hk32f030m_gpio.h(119): warning: padding size of 'GPIO_InitTypeDef' with 3 bytes to alignment boundary [-Wpadded]

请问怎么消除啊?
