> Or we just don't care ? I think currently only the module loader worries about changing TOC pointers, but perhaps we should think about it in other places too. What do you do on 32-bit though? Still, I think that would be a new separate macro, so this stands on its own IMHO. cheers -- Michael Ellerman OzLabs, IBM Australia Development Lab wwweb: http://michael.ellerman.id.au phone: +61 2 6212 1183 (tie line 70 21183) We do not inherit the earth from our ancestors, we borrow it from our children. - S.M.A.R.T Person
