No, those instructions simply do not exist.
Well the datasheet gives a list of the instructions that are
implemented, e.g. efsadd, efdadd, efvsadd (it even has vector
support).
Those are instructions belonging to some specific embedded extension
(BookE or so). Those instructions do not exist on a regular ppc
(they're also not altivec instructions).
I guess the fpu control instructions are missing.
I'm pretty sure all regular fpu instructions are missing.
