We're looking at two different ifs here.
1) GPR Inside the PACA or not (volatile vs non-volatile)
This is constant. Volatile registers go to the PACA; non-volatiles go to
the vcpu struct.
Okay - so no if ().
Eh.
r[0 - 12] are volatile
r[13 - 31] are non-volatile
So if we want a common gpr access function we need an if. And we need
one, because the opcodes just use register numbers and doesn't care
where they are.
I see - we have something similar on x86 (where vmx keeps rsp/rip in a
register and lets us save everything else manually).
