As, I looked I think we need to make changes here to handle it : https://github.com/llvm/llvm-project/blob/e3ee6bbd384ef4c583b9f7bca4253ae0fba90a70/llvm/utils/TableGen/Common/CodeGenRegisters.cpp#L415

So, anyone taking care of it as of now, because its needed to be done for my work to move forward?
