STM32F103固件库编程：关于core_cm3.c的错误

STM32F103固件库编程：关于core_cm3.c的错误。

解决方法有两种：

1。直接删除固件库中的core_cm3.c文件，keil已有替代文件。

2。ARM编译器版本从6，改回到5。

提示错误如下：

../Lib/CMSIS/CM3/CoreSupport/core_cm3.c(445): error: non-ASM statement in naked function is not supported
  uint32_t result=0;
  ^
../Lib/CMSIS/CM3/CoreSupport/core_cm3.c(442): note: attribute is here
