We have Jeff Dionne, founder of uclinux and developer of uc-libc (which Erik forked to make uClibc, do "git log | cat" and look at the next to last commit) contributing to the musl-sh2 discussion. I'm trying to get the thread restarted and the existing messages posted to the musl list so they're archived somewhere. Jeff's CEO of a tech start in Japan these days so _really_ busy, but still brilliant and the world's leading expert on a lot of nommu stuff if you can get his time. Not that I'm exactly unbiased here. He's my boss at $DAYJOB and I'm appearing on a panel with him and the original superh processor architect at linuxcon japan on thursday: http://lccojapan2015.sched.org/event/860288ccda595208a5d7337d31c6075c#.VWv3sR-1XVN Still, _that_ is the discussion you want to get in on...
