Are you sure those arent the old POWER instructions as in pre-powerPC
architecture that 601 (and only 601) supports ?

All 32-bit hash based CPUs are arch 1.x and support rfi
All 64-bit hash based CPUs we support (ie, POWER4 and later) are
architecture 2.x and later.
So my test is correct in the context of what we emulate today.
Cheers,
Ben.
