core_cmFunc.h中的enable_irq(void)在GNU编译器下才起作用吗？？

咸鱼打架

#elif defined ( __GNUC__ ) /*------------------ GNU Compiler ---------------------*/
/* GNU gcc specific functions */

/** \brief  Enable IRQ Interrupts

  This function enables IRQ interrupts by clearing the I-bit in the CPSR.
  Can only be executed in Privileged modes.
*/
__attribute__( ( always_inline ) ) __STATIC_INLINE void __enable_irq(void)
{
  __ASM volatile ("cpsie i" : : : "memory");
}


/** \brief  Disable IRQ Interrupts

__attribute__( ( always_inline ) ) __STATIC_INLINE void __disable_irq(void)

上面应该有其他编译器的汇编指令啊
