Oops! No need of Call Graph! In fact, what I want to do is to find which function is the kernel function and which function is called by that kernel. Since OpenCL will make all functions called by kernels inline, I can use function attribute: Noinline to distinguish them. Sorry for bothering you. Antony Yu -- View this message in context:

You shouldn't rely on that, its an implementation detail. Instead, you can trace back to the original Function object and check for kernel metadata.
