[Pipeliner] MachinePipeliner TargetInstrInfo hooks need more information?
...iables, comparisons and branches. So when it came to implementing
reduceLoopCount for our TargetInstrInfo, we found that we didn't have
enough information from analyzeLoop to reduce the loops.
Currently the signatures look like this:
bool analyzeLoop(MachineLoop &L, MachineInstr *&IndVarInst,
MachineInstr *&CmpInst)
unsigned TargetInstrInfo::reduceLoopCount(MachineBasicBlock &MBB,
MachineInstr *IndVar,
MachineInstr &Cmp,
SmallVectorImpl<MachineOperand> &Cond,
SmallVectorImpl<MachineInstr *> &Pr...
