[LLVMdev] LiveIntervals, replace register with representative register?
...gister with one of a virtual register (and this > real register will be the representative register of the set of > intervals joined together). I understand the representative register could be a physical (real) register if one of the coallescing register is a physical register. But the code _uncondtionally_ changes MachineOperand::optype to MO_MachineRegister, why?

[LLVMdev] LiveIntervals, replace register with representative register?
I don't understand the following code snippet in LiveIntervalAnalysis.cpp. Why changing the type of the opreand from a virtual register to a machine register? The register number (reg) is still a virtual register index (>1024). bool LiveIntervals::runOnMachineFunction(MachineFunction &fn) { // perform a final pass over the instructions and compute spill // weights, coalesce
