Could you please move the kernel source code to file instead of staying in host code?
You can refer to my pending patch "move enqueue_copy_image kernels outside of runtime code", thanks.

The one index indicate to one kernel string, because you add a new kernel for CL_ENQUEUE_COPY_BUFFER_RECT, you should also add a new index for it.
And the file mode change 100644 => 100755, I think it is not necessary.
