--- Comment #4 from Simon Pilgrim <llvm-dev at redking.me.uk> ---
Resolving - we now have 'basic' (cycle/uops) counter coverage for most AMD CPUs
going back well over a decade, and FPU perf counters for btver/bdver/znver
targets (annoyingly AMD's perf counters for other ALUs is awful).

Even if the CPU doesn't have a scheduler model, llvm-exegesis will report the
counters we now specify, which should help anyone that wants to create the
missing models.
