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. r~
