[LLVMdev] Out of tree targets: Possibly additional API to implement for out of tree targets using the IfConverter
...ange. Targets
that move over to the new schedule model will be able to use the new schedule
module for instruction latencies in the if-converter (the logic is such that if
there is no itinerary we will use the new sched model for the latencies).
Before, we queried "TTI->getInstructionLatency()" for the instruction latency
and the extra prediction cost. Now, we query the TargetSchedule abstraction for
the instruction latency and TargetInstrInfo for the extra predictation cost. The
TargetSchedule abstraction will internally call "TTI->getInstructionLatency"...
