Dalvik seemed intentionally as different from a conventional JVM as possible .. register-based rather than stack-based That's because register IRs are easier to optimize than stack based ones. Have you heard of SSA? the canonical intermediate representation for high performance compilers; yeah, it's register based. And Dalvik wasn't the first recent VM to be that "different"; heard of Parrot? it's register based.
