It *was* neatly defined:
"The types defined in this manner can be used with a subset of normal 
C operations. Currently, GCC will allow using the following operators on 
these types: +, -, *, /, unary minus, ^, |, &, ~.".


So can you, pretty please, also patch the documentation and maybe point 
to the Altivec spec as it's obviously the only one relevant no matter 
what platform you're on?
