--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Well, libcpp isn't using the standard Altivec intrinsics, but their gcc
underlying implementation.  Looking at clang altivec.h, I see they use vect=
or
keyword everywhere and not sure what exactly they map it to under the hood,=
 but
clearly not to altivec attribute, and they have different __builtin_* calls=
 to
implement e.g. vsx_ld and the like.=
