shouldScheduleVOPDAdjacent()

static bool shouldScheduleVOPDAdjacent ( const TargetInstrInfo &  TII, const TargetSubtargetInfo &  TSI, const MachineInstr *  FirstMI, const MachineInstr &  SecondMI  )

static

Check if the instr pair, FirstMI and SecondMI, should be scheduled together.

Given SecondMI, when FirstMI is unspecified, then check if SecondMI may be part of a fused pair at all.
