The only non test user of the assembler prefetch functions is the heapBits.prefetch function which is itself unused. The runtime prefetch functions have no functionality on most platforms and are not inlineable since they are written in assembler. The function call overhead eliminates the performance gains that could be achieved with prefetching and would degrade performance for platforms where the functions are no-ops. If prefetch functions are needed back again later they can be improved by avoiding the function call overhead and implementing them as intrinsics.
