If you want to see hardfloat for PPC then you should read the replies to 
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 
exceptions cached in a global that maybe could work. I won't be able to do 
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 
are in the same situation so unless somebody puts in the necessary effort 
this won't change.
