Oh, I see, well. There are a couple of things you guys should try:

Use linker/cecil to merge all assemblies before AOT'ng them. This should
save some bytes.

Improve the linker and your linker scripts to be more aggressive and make
more assumptions.

Improve the arm codegen to emit more compact code.

Move some code emitted by the full AOT mode to be fixed functionality of the
runtime.

Fix the runtime so it can be compiled with thumb.

Port the JIT to emit thumb.

Strip more functionality of the runtime.
