Hi Doko,
to understand this right, the new will be -march=power9 then?
If yes, that implies that any power8 test machine won't be usable for >=jammy.
I just wanted to spell this out so that the implication is clear since
I think while
P8 machines are old they are in common use as test system AFAIK.
