Subtarget Initialization in <ARCH>TargetMachine constructor
...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

Subtarget Initialization in <ARCH>TargetMachine constructor
Hi,
I found some different discrepancy on how Subtarget is created
between some arch specific TargetMachine constructor.
For example, for BPF/Lanai:
BPFTargetMachine::BPFTargetMachine(const Target &T, const Triple &TT,
StringRef CPU, StringRef FS,
const TargetOptions &Options,
