True, Google is working on LTO, but their focus is on *extremely* large
applications and to make them smaller. So, while I like to be optimistic about
the future of LTO, I'm reserving judgement until I see it actually working, and
see how it works on an AVR application. But that's the other main problem: LTO
is on a branch and is not ready for prime-time yet (but it's getting closer),
whereas -fwhole-program exists now.

I'm pretty sure that Atmel already knows that.

This is good to know! Thanks! :-)

There hasn't been much in the past, but that will change significantly in the
near future.
