Hey, I wanted to add an intrinsics to read MSRs. So I added the intrinsics and lowered it to a new ISD node I created ISD::RDMSR, its first operand is the MSR id. I added a case in X86DAGToDAGISel::Select for ISD::RDMSR. Now I know rdmsr works like so: mov r/ecx, <id> rdmsr r/eax holds the lower 32/64 bit >From what I understood this needs a Token Factor node, nodes which are
