[Qemu-devel] S/390 Host support status

[Qemu-devel] S/390 Host support status

[Thiemo Seufer]

This is the remaining bit of s390 host support code from your earlier
patch. Could you check if this bit is still needed?

Also, if it does something useful, I suspect that it is incomplete.
gen_setcc duplicates the same logic, wouldn't it need to stay in sync?
