I do not understand how your question follows from my comment.
The Altivec intrinsics are not actually function calls. No
arguments are passed and no results returned through any parameter passing
mechanism. Everything is within a single Altivec instruction. If GCC is
complaining about the intrinsic because it looks like a function call, GCC
