I happened help tilegx, because Adrian found someone with hw and tilegx
appeared to be very well maintained upstream. Very little needed to be
done to make it work in Debian. The patches I sent were pretty generic
and addressed issues that most ports face. What is there allows
constructing most of an essential package set and (unlike a number of
other architectures) bootstrapping tilegx works fairly well.  Debian has
a number of source-only ports and tilegx is now one of them.

That said, nobody has taken up the work to proceed a native bootstrap.
Like with nios2, progress is stalled, because the tooling for fully
automating the native phase is missing.

In any case, I won't be able to fix binutils/gcc/glibc/linux issues with
tilegx. So unless someone steps up to do that work, I won't object to
dropping it. It would be sad to see tilegx go, but it certainly isn't my
core interest either.

I'd appreciate a note if it gets dropped from any of these, because I'd
clean up outstanding bug reports then.

The reverse is also true: If you want to see an new architecture in
Debian, I also appreciate an early conversation to avoid duplicating
work.

Hope this helps

Helmut
