I'd like to see hard float to be landed:) If you want to see hardfloat for PPC then you should read the replies to=20 this patch which can be found here: http://patchwork.ozlabs.org/patch/1240235/ to understand what's needed then try to implement the solution with FP=20 exceptions cached in a global that maybe could work. I won't be able to d= o=20 that as said here: https://lists.nongnu.org/archive/html/qemu-ppc/2020-03/msg00006.html because I don't have time to learn all the details needed. I think others= =20 are in the same situation so unless somebody puts in the necessary effort= =20 this won't change. Regards, BALATON Zoltan --3866299591-1597789169-1586541893=:33850--
