Maybe not, but we are in fact actively developing.  :-)

Good to hear.

The nanoMIPS toolchain we inherited is based on gcc 6.3.  We’ve been working on 
upgrading to gcc trunk since late February, but it's not a trivial task.  As 
soon as we're done (hopefully before the summer), we'll propose the changes to 
the gcc mailing list.

Ouch.  I understand that's a big job rebasing to mainline.

In sum, we're investing in open source nanoMIPS tools because it's an important 
technology for us, and QEMU is one of the key projects we want to have nanoMIPS 
supported in.

Well, hopefully that means you'll have made some progress by late summer, when qemu 6.1 is due.
