...what I did). I’d be happy to help out someone who wants to do this. It would be nice to get this working without embedding any of Objective-C to the host process this is why I am particularly interested in knowing how to do the work that objc4 does in the methods such as: objc4/_objc_init, objc4/map_images_nolock and objc4/_read_images. My understanding of the goal is to make the lli example from this thread working: https://stackoverflow.com/questions/10375324/all-selectors-unrecognised-when-invoking-objective-c-methods-using-the-llvm-exec. I would be happy to get a hint on which functions of Objective-C...
