LLVM has a JIT for this purpose. You generate LLVM IR code (a sort of
generic assembler) and it produces optimized native code ready to be
executed.

x86-win32 is fine. I don't think so about arm-wince.

This is a list of some of the projects that uses LLVM:

The LLVM tutorial is worth a reading too:
