Yes .. but not in FSF gcc source. There is a separate sourceforge
project for it.

Ditto for gdb.

binutils builds.

This is a small architecture and a port would probably want to
use the msp430 C library. I didn't look at the license.

It appears to be divided into a "portable" and CPU model part.
Figuring out how to handle this in a general way would be required.

I came across one in Java which appears GUI heavy and didn't look
to be updated in 5 years. I saw another but the links died.

Small like the avr.  C library gets tailored to microcontroller model.

Cynthia's work to use avr-libc, disable POSIX etc. and use Classic API
only would be beneficial

My initial impression is that even though RedHat did the port, it is
in an unmerged and possibly out-dated state.

If someone wants to dig through source and find out who did the
work, I can contact them about what happened. But at this point,
those independently maintaining it would have to have FSF assignments
and want to do the work to get it merged.
