PowerPC optional instructions

Hi,

while optimising my code, I came across a compiler warning that the 'fres' (reciprocal estimate) instruction is optional in the PowerPC architecture.

Can anyone point me at a list of which optional instructions are supported on which Apple processors?

I'm only really interested in supporting G3s and above.


cheers,
os.
