Some issues:


- The compiler should run on the target system. This implies, that the
compiler is an executable program for the target platform.


- Above dictates, which constraints apply to the conversion of the
input code (OS, instruction set...).


- You didn't specify the nature of the input code. An emulator takes
any program, executable on a different platform, and executes it on
the actual platform. That's the worst case, where nothing else is
known about the input, besides that it's a native program for a
specific platform. If your object of interest is less
platform-dependent, you should specify...
