-Some platforms like the iphone prohibit JITted code, using technical and/or legal means. This is a significant problem for the mono runtime, since it generates a lot of code dynamically, using either the JIT or more low-level code generation macros. To solve this, the AOT compiler is able to function in full-aot or aot-only mode, where it generates and saves all the neccesary code in the aot image, so at runtime, no code needs to be generated.

To solve this, the AOT compiler is able to function in full-aot or aot-only mode, where it generates and saves all the necessary code in the aot image, so at runtime, no code needs to be generated. There are two kinds of code which needs to be considered:
 
 -   wrapper methods, that is methods whose IL is generated dynamically by the runtime. They are handled by generating them in the add_wrappers () function, then emitting them as 'extra' methods.
 -   trampolines and other small hand generated pieces of code. They are handled in an ad-hoc way in the emit_trampolines () function.

 -   To allow mono_raise_exception () to unwind through native code, we need to save the LMF structures which can add a lot of overhead even in the common case when no exception is thrown. So this is not zero-cost exception handling.
 
-An alternative might be to use a JNI style set-pending-exception API. Runtime code could call mono_set_pending_exception (), then return to its caller with an error indication allowing the caller to clean up. When execution returns to managed code, then managed-\>native wrapper could check whenever there is a pending exception and throw it if neccesary. Since we already check for pending thread interruption, this would have no overhead, allowing us to drop the LMF saving/restoring code, or significant parts of it.

There is a separate pass, mono_handle_global_vregs (), which verifies this invariant and transforms lvregs into global vregs if neccesary.
