There was some attention given to using the DragonEgg project for this purpose. I don't think it ever gained any traction, unfortunately. One unfortunate factor that inhibits the porting of Ada to new platforms is that the language's real power lies in it's runtime library. Whether or not your compiler can target a specific architecture is only part of the problem of cross-platform development. In order to use the compiler for development on the target platform you'll need a functioning RTS.
