这个是CMSIS DSP库啊，，，我看开头
#if defined ( __CC_ARM ) /* Keil */
#define CODESECT AREA ||.text||, CODE, READONLY, ALIGN=2
#define LABEL
#elif defined ( __IASMARM__ ) /* IAR */
#define CODESECT SECTION `.text`:CODE
#define PROC
#define LABEL
#define ENDP
#define EXPORT PUBLIC
#elif defined ( __CSMC__ ) /* Cosmic */
#define CODESECT switch .text
#define THUMB
#define EXPORT xdef
#define PROC :
#define LABEL :
#define ENDP
#define arm_bitreversal_32 _arm_bitreversal_32
#elif defined ( __TI_ARM__ ) /* TI ARM */
#define THUMB .thumb
#define CODESECT .text
#define EXPORT .global
#define PROC : .asmfunc
#define LABEL :
#define ENDP .endasmfunc
#define END
#elif defined ( __GNUC__ ) /* GCC */
#define THUMB .thumb
#define CODESECT .section .text
#define EXPORT .global
#define PROC :
#define LABEL :
#define ENDP
#define END
.syntax unified
#endif
应该有考虑兼容GCC 语法。。。
