--- Comment #2 from Max <f.mach4 at gmail dot com> ---
I am interested in working on this, because it would be a big shame to see AVR
support dropped from GCC. However, while I studied computer science at
university and of course have decent experience with the AVR platform, I do not
have a background in compilers nor have ever contributed to GCC before.

I have read some of the GCC internals manual and browsed around the source
tree, including gcc/config/avr, but I am still missing out on some foundational
understanding of how everything fits together inside GCC. 

Is there anyone more familiar with GCC internals and/or the AVR backend who I
would be able to consult or possibly work with on this?
