Does anyone know an open-source C++ x86 SIMD intrinsics library?

Intel supplies exactly what I need in their integrated performance primitives library, but I can't use that because of the copyrights all over the place.

EDIT

I already know the intrinsics provided by the compilers. What I need is a convenient interface to use them.
