fp64 usage in kernel

I want to have one kernel for devices that supports double precision and another one for those who lack fp64.

 

Will

#ifdef cl_khr_fp64

// fp64 kernel

#else

//fp32 kernel

#endif

be enough in CL file for that?

Or I should enable corresponding extension via pragma?

If yes, how I could know for what device is legal and for what is not legal to enable fp64?
