[LLVMdev] how to do make a FP_ROUND need/operattion

[Zhang, Kewu]

Hi Guys,

I and trying to covert a float to a f16.
calling


 DAG.getNode(ISD::FP_ROUND, DL, Op->getValueType(0), FloatNode);


will get the error message:"Invalid method to make FP_ROUND node"


what is the "right" way to make this work?


best

Kevin
