Unity compilation process - JIT and AOT?
In the docs, it seems Unity compiles all scripts to dlls, which are JIT compiled at runtime. http://docs.unity3d.com/Documentation/ScriptReference/index.Script_compilation_28Advanced29.html
Is JIT always used?
Where does AOT fit in, and is AOT done only for some platforms? Are both AOT and JIT used for each platform?
When AOT-compiled, do we lose any functionality?
Also, if you use generics, does that force your AOT to actually be JIT?
On iOS devices scripting languages are explicitly prohibited by Apple, so on that platform we AOT (ahead-of-time) compile the code into assembler during the build process. When you use AOT reflection is not supported, since this typically generates c# at run-time.
HI Graham, can you explain how components relate to AOT/JIT, i.e., are Unity components compiled to their own assembly http://answers.unity3d.com/questions/346501/unity-as-a-components-based-system.html
Here's possibly a better question - http://answers.unity3d.com/questions/346881/how-does-unity-compilation-work.html
On iOS, scripting languages aren't prohibited, you just aren't allowed to dynamically generate code. So you can use a scripting language with an interpreter, but you can't use a JIT interpreter or any kind of interpreter that dynamically compiles to native code.
