I was thinking of doing this in a separate patch, and we may want to have a different category for the GPU that indicates if it's implemented natively or if we rely on the vendor. Then we'd have some documentation about the considerations of GPU math, like reduced precision, ULP modes, linking to vendor documentation for those functions, etc.
