Hi Eli, I would like to clarify generally what the difference is between returning SDValue() and Op (input argument unchanged) from LowerOperation()? My understanding is that returning SDValue() means that Target gives up, and the common code is supposed to handle it. Returning Op, the unchanged argument, means that the Target is happy with the node as it is, and the common code can move on

...This sounds backwards. Returning SDValue() means the node should be treated as legal. Returning the original operation should hit the expand path. -Matt -------------- next part -------------- An HTML attachment was scrubbed...
