...9;m trying to rework this : I'd like that a "DST = FNEG SRC" custom Emitter lowering pass replaces every occurence of DST by SRC and set the corresponding TargetFlag in the process. Something like this : MachineOperand *MO = &(MI->getOperand(0)); while(MO) {   MachineOperand *next_MO = MO->getNextOperandForReg();   MO->addTargetFlag(MO_FLAG_NEG);   MO->setReg(MI->getOperand(1).getReg());   MO = next_MO; } As far as I can tell, this works as every register are still virtual when lowering custom Emitter instructions. However the RegisterCoalescer pass does not preser...
