What i don't see now is an obvious way of telling which register sets
are available for core files in PowerPC. You'd have to infer that based
on dynamic data.
It is my personal view on the change, really. I don't claim it is right
or wrong.
Also, why is the PowerPC backend being modified together with S390? Is
this a change to account for POWER8? The introductory mail does not
mention anything PowerPC-specific.
