Eli, I have a simple SplitVecRes function that implements what you mentioned, splitting the LHS just as in BinaryOp, but passing through the RHS. The problem is that the second operand is MVT::Other, but when casted to an VTSDNode reveals that it is a vector length of the same size as the LHS SDValue. This causes a split on the LHS side to work correctly, but then it fails instruction selection because of Other. I have not been able to figure out how to split the MVT::Other node yet, any idea how to do this? Instruction sel...

Thanks Eli, I'll see if I can get something working and submit a patch.

Eli, I don't see how this helps with the splitting of the Other node as it isn't the Dest that is the problem, but the second source value. Any place in the code that I can look at on how to split a VTSDNode?

Hello, in some operations there is a ty2 type, for example in truncate. What is the most right way to get it ? I have seen some EVT types, but this is connected to DAG... and I don't believe that there is no easy way to get ty2 with one call function. -------------- next part -------------- An HTML attachment was scrubbed...
