We just recently updated to Xcode6, and we a lot of errors in arm_neon.h we are using glkit framework to build our app.
我们刚刚更新到Xcode6，在arm_氖中有很多错误。我们正在使用glkit框架来构建我们的应用程序。
Here the error in arm_neon.h:
这里是arm_新生儿的错误。

It ONLY occurs when we tried to build it in device, it builds well on simulators.
它只发生在我们试图在设备中构建它时，它在模拟器上很好地构建。
Thanks.
谢谢。

i did a temporary fix for this, directly editing arm_neon.h changing the __fp16 to a short data type.
我做了一个临时修复，直接编辑arm_氖。将__fp16更改为一个短数据类型。

ultimately we found out that our project was defining __fp16 to something else causing the problem.
最终，我们发现我们的项目将__fp16定义为其他导致问题的原因。
