[LLVMdev] Machine LICM and cheap instructions?
...ssure situations, it will refuse to hoist "cheap" instructions out of loops. By default, when an itinerary is available, this means that all of the defined operands are available in at most 1 cycle. ARM overrides this, and provides this more-customized definition:
bool ARMBaseInstrInfo::
hasLowDefLatency(const InstrItineraryData *ItinData,
const MachineInstr *DefMI, unsigned DefIdx) const {
if (!ItinData || ItinData->isEmpty())
return false;
unsigned DDomain = DefMI->getDesc().TSFlags & ARMII::DomainMask;
if (DDomain == ARMII::DomainGeneral) {
unsigned...
