LS,

Suppose I want to simulate, using qemu, a Ryzen znver3 processor, what -cpu flag do I set? The current list for qemu does not include any Ryzen/Threadripper cpu. So, I can optimize code using -mtune of -march for gcc, but these flags do not correspond with qemu's processor list.

Regards, Frans.
