[kvm-unit-tests PATCH v2 2/5] s390x: fix storing/loading fregs to right address

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



LARL is wrong here, as we specify an explicit address. Let's use LA
(we could also drop it and fixup all loads/stores, but this is easier).
