If you want to more seriously test the PPC instructions
it might be worth extending risu to cope with more than
just the ARM architecture...
That would be a moderate chunk of work -- about 300 lines
of C code in the client, plus refactoring the generator
perl script to separate out the architecture-dependent
bits and add ppc support. The advantage is that once
you've done it it's very easy to add support for testing
a single instruction, provided you have a known-good
hardware implementation to be the reference.

(one day soon I will have to make it cope with aarch64)
