	- Use of ObjC blocks is disabled and therefore the ``enqueue_kernel`` builtin
	function is not supported currently. It is expected that if support for this
	feature is added in the future, it will utilize C++ lambdas instead of ObjC
	blocks.

	- IR generation for global destructors is incomplete (See:			- IR generation for global destructors is incomplete (See:
	`PR48047 <https://llvm.org/PR48047>`_).			`PR48047 <https://llvm.org/PR48047>`_).

	- There is no distinct file extension for sources that are to be compiled
	in C++ for OpenCL mode (See: `PR48097 <https://llvm.org/PR48097>`_)
