[LLVMdev] [LLVMDev] Live Intervals and Finding the next usage
I am looking for the slot index of a register around the given slot index
Min. Is there a better way than the linear search:
...

...
for( MachineOperand * mo = MRI->getRegUseDefListHead(li->reg);
mo; mo = mo->getNextOperandForReg() )
{
SlotIndex si = SI->getInstructionIndex( use.getOperand().getParent() );
