Thanks for your reply Quentin. I do understand that the registers are allocated much later in the pipeline. I am assuming that the physical registers are allocated before MipsAsmPrinter class. I am doing something like if (MI->getOpcode() == Mips::OPCODE) { unsigned n = MI->getNumOperands(); for(unsigned i=0 ; i < n ; i++) { const MachineOperand &MO =
