About the dexopt language thing, I think there are relatively safe deductions
that can be made. dx and a version of dexopt are added to the JDK so that
developers can compile and optimise code before loading in on to a 'phone.
The JDK tools run on the SE Java run-time engine. I think it is safe to assume
that both dx and dexopt are written in Java if only because dexopt is called
from two java language programs (from the original Mitchell expert report).
As you rightly deduced, there is no way to run a java dexopt program on an
Android phone. As Josh Bloch explained (and as considered in your parent post)
dexopt, on the 'phone for the automatic installation of downloaded apps, needs
to process .dex files into optimised files.
In order to use components of the Dalvik run-time engine, I think it is a safe
conclusion that it is written in Dalvik byte code. My guess is that it is a .dex
file that only requires components rather than the full Dalvik run-time.
