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 -------------- next part -------------- An HTML attachment was scrubbed...
