With this patchset, I can boot a kernel compiled for z14 (requiring
Miscellaneous-Instruction-Extensions Facility 2) (using -cpu max).
I am currently working on "vector-enhancements facility 1", I have most
stuff in place except:
- VECTOR FP (MAXIMUM|MINIMUM): needs some manual work to cover all types of
comparisons.
- VECTOR FP (NEGATIVE) MULTIPLY AND (ADD|SUBTRACT): needs float128_muladd()
Once we have that in place, we can convert the QEMU machine to a
stripped-down z14.
