@sharkautarch Maybe I am reading it wrong, but doesn't Syklake inherit TuningLZCNTFalseDeps via Haswell and Broadwell tuning, hence it gets passed down to ADLTuning as well at the moment? At least TuningLZCNTFalseDeps is set in the Haswell section (https://github.com/llvm/llvm-project/blob/66a2d1b7580aab8ac2c171647c39fd85fe711013/llvm/lib/Target/X86/X86.td#L950) and cannot see it getting unset in the later models.
