ARM工具链

ARM 系列目前支持三大主流的工具链,即ARM RealView (armcc), IAR EWARM (iccarm), and GNU Compiler Collection (gcc).

   core_cm3.h中有如下定义:
    /* define compiler specific symbols */
  #if defined ( __CC_ARM )
     #define __ASM __asm /*!< asm keyword for armcc */
     #define __INLINE __inline /*!< inline keyword for armcc */
 #elif defined ( __ICCARM__ )
     #define __ASM __asm /*!< asm keyword for iarcc */
     #define __INLINE inline /*!< inline keyword for iarcc. Only
                                   avaiable in High optimization mode! */
     #define __nop __no_operation /*!< no operation intrinsic in iarcc */
 #elif defined ( __GNUC__ )
     #define __ASM asm /*!< asm keyword for gcc */
     #define __INLINE inline /*!< inline keyword for gcc
