-Current state of this is that the generation of runtime structures is updated for the kernel module as well as the usage of integer-based selector.
+Current state of this is that the compiler emits the correct kernel runtime structures and the selector types have been updated to use the integer-based type.

+It is still missing some changes from libunwind-based stack unwinding and exception handling to the setjmp-longjmp-based one.
+
+An example of how the setjmp-longjmp-exception-handling-protected message calls should work is done in file CGObjCGNU - method callIMP. There's a few more places the libunwind-based invocations need to be replaced with similar calls (just search for IRBuilderCreateInvoke).

+
+Unfortunately, for reasons I haven't yet unraveled, the edlc process crashes in the callIMP function (on return from the function), failing a function cast assertion - however, only if the actual return type is void.

 An extension to this project is getting Smalltalk into the kernel. The Smalltalk runtime in included as well and it uses the ObjC runtime for all its features.
