--- Comment #4 from hengxu010 <hengxu at bao dot ac.cn> --- Hi Iain , thank you very much! I'm very happy to hear that you have'd already implement the support for 16 bite float type in the development version of gcc, I can try that later. Hope the official version can be online soon. And thank you for taking time for answering these questions.
