static bool | shouldScheduleAdjacent (const TargetInstrInfo &TII, const TargetSubtargetInfo &TSI, const MachineInstr *FirstMI, const MachineInstr &SecondMI) |
Check if the instr pair, FirstMI and SecondMI, should be fused together. | |
std::unique_ptr< ScheduleDAGMutation > | llvm::createX86MacroFusionDAGMutation () |
Note that you have to add: DAG.addMutation(createX86MacroFusionDAGMutation()); to X86PassConfig::createMachineScheduler() to have an effect. | |

Check if the instr pair, FirstMI and SecondMI, should be fused together.
Given SecondMI, when FirstMI is unspecified, then check if SecondMI may be part of a fused pair at all.
