...ather than a subclass of Subtarget. The following is what I observed: Both Subtarget constructor and initAsmInfo will eventually create a MCSubtargetInfo, which calls InitMCProcessorInfo. void MCSubtargetInfo::InitMCProcessorInfo(StringRef CPU, StringRef FS) { FeatureBits = getFeatures(CPU, FS, ProcDesc, ProcFeatures); if (!CPU.empty()) CPUSchedModel = &getSchedModelForCPU(CPU); else CPUSchedModel = &MCSchedModel::GetDefaultSchedModel(); } If you have -mcpu=help in your command line llc -march=<> -mcpu=help ...
