#ifdef INCLUDE_KERNELFUNCTION_TABLES

/*! \brief Declare and define the kernel function pointer lookup tables.
 *
 * The minor index of the array goes over both the LJ combination rules,
 * which is only supported by plain cut-off, and the LJ switch/PME functions.
 * For the C reference kernels, unlike the SIMD kernels, there is not much
 * advantage in using combination rules, so we (re-)use the same kernel.
