built in dot & cross products


Are there any built in intrinsics for dot & cross products ?
I don’t see any definitions of those in headers
Or the common way to do this is:
inline device float dot(float3 a, float3 b)
return a.x * b.x + a.y * b.y + a.z * b.z;
and let’s the compilator vectorize the code ?

I’v use a lot of dot & cross products (on float3 and float4 datatypes)
in my kernel, and i’m curious if there is any ‘optimized intrinsic’ for this.

An example library of vector functions is included in the SDK in “cutil_math.h”.

The G8x hardware is scalar, so there are no vector intrinsics.
