"The best way to save power is to just optimize for overall execution time, to
reduce how long the CPU has to be active."

Perhaps not entirely true, but it may require the compiler to know
more about the whole system and is able disable parts of the system it
knows aren't necessary by code analysis. Not that I have any real data
to back that up.

This paper does seem to have some problems though.
