I think it should be ret. i'm pretty certain this should be lret. Basically either the osx assembler should support retf(which I have a patch for, but probably won't happen ever) or it should use lret, which is exactly the same instruction.

I gave up at this point. This is a major PITA. At this point my recommendation is to make a gcc 48 efi cross compiler. Andrew gave me some help for these too, but I don't think it's worth exploring. Even if you manage to this to compile somehow the emulator will crash. At least it did for me. Basically the osx linker does not support PIE(amongst other things). You can build an efi cross compiler with the code available here: https://github.com/STLVNUB/CloverGrower personally I modified the script for easier and stripped down use.
