[LLVMdev] SplitVecRes with SIGN_EXTEND_INREG unsupported
Eli,
I think I was able to get it working. Thanks for the help, does this look correct to you?
void DAGTypeLegalizer::SplitVecRes_SIGN_EXTEND_INREG(SDNode *N, SDValue &Lo,
SDValue &Hi) {
SDValue LHSLo, LHSHi;
GetSplitVector(N->getOperand(0), LHSLo, LHSHi);
DebugLoc dl = N->getDebugLoc();
EVT LoVT, HiVT;
GetSplitDestVTs(N->getValueType(1), LoVT, HiVT);
Lo = DAG.getNode(N->getOpcode(), dl, LHSLo.getValueType(), LHSLo, DAG.getValueType(LoVT));
Hi = DAG.getNode(N->getOpcode(), dl, LHSHi.getValueT...

[LLVMdev] SplitVecRes with SIGN_EXTEND_INREG unsupported
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?
Thanks,
Micah

So, how would I be able to split the Other node so that it will match the resulting data type?
My function looks like this:
void DAGTypeLegalizer::SplitVecRes_SIGN_EXTEND_INREG(SDNode *N, SDValue &Lo,
SDValue &Hi) {
SDValue LHSLo, LHSHi;
GetSplitVector(N->getOperand(0), LHSLo, LHSHi);
SDValue RHS = N->getOperand(1);
DebugLoc dl = N->getDebugLoc();
Lo = DAG.getNode(N->getOpcode(), dl, LHSLo.getValueType(), LHSLo, RHS);
Hi = DAG.getNode(N->getOpcode(), dl, LHSHi.getValueType(), LHSHi, RHS);
}
Thanks,
Micah

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