--- Comment #7 from David Edelsohn <dje at gcc dot gnu.org> ---
One can experiment with implementing libmvec against the VSX intrinsics. The
intrinsics are implemented in GCC, LLVM and XLC.
The mmintrin support in GCC is implemented on top of the VSX intrinsics.
One must look at the resulting code to see if it truly is optimized, and
whether the intrinsic could be improved or the particular function must be
implemented more directly in assembly language. The answer may be a
combination of the approaches.
