Well, no. As Android targets any processor - not just ARM. Indeed, there
are Intel based versions. Native is bad, and only come in to existence
to compete with other platforms with purely native compilation - and
then purely to counteract criticisms on the performance of games and
multimedia apps. Davlik was created for a reason - compile once, run on
multiple targets. Would it not be a better solution to create a Dalvik
back-end? As I understand it, Dalvik is very, far from a traditional
stack based Java VM and closer to a traditional register based processor
in design. I know little about it, but the benefits of Android, as a
platform, are completely lost when one focuses on native compilation.
I don't see it that problematic to create a Dalvik code generator (or a
normal Java or CIL one). The biggest problem is to create a suitable RTL and
to be able to use the classes that are provided by the VM.
In fact I think this is one of the more easy things.
The main problem seems to me that you need to support things like pointers,
which is something deeply embedded in Pascal.
Michael.
