Member Function Documentation

bool llvm::InstrItineraryData::isEmpty

(

)

const [inline]

isEmpty - Returns true if there are no itineraries.

Definition at line 61 of file TargetInstrItineraries.h.

References Itineratries.

Referenced by llvm::ScheduleDAGInstrs::ComputeLatency(), and getLatency().

const InstrStage* llvm::InstrItineraryData::begin

(

unsigned

ItinClassIndx

)

const [inline]

begin - Return the first stage of the itinerary.

const [inline]

end - Return the last+1 stage of the itinerary.

Definition at line 72 of file TargetInstrItineraries.h.

unsigned llvm::InstrItineraryData::getLatency

(

unsigned

ItinClassIndx

)

const [inline]

getLatency - Return the scheduling latency of the given class. A simple latency value for an instruction is an over-simplification for some architectures, but it's a reasonable first approximation.
