Cool, thanks for the details. I guess I should check who's asking before I respond the next time around. ;) It wasn't clear whether you're pulling my leg or you're interested in deep dive I can't provide. But you can. :] So, question then - wasn't it the case (at one point) that you had dependency on stack unwinding library or some external implementation of TLS? My feeling is that what I read about OS development at that point had also something to do with one of these two. Maybe. Unwind is native to Rust right now and is no longer a problem (on platforms supported), no?
:) It's all good, I was a little bit terse... I should consider that in the future.
We do use gcc's unwinding library, last I recall, but if you're writing an OS, you can implement the language items to do whatever you want, including just abort.
There's no inherent TLS implementation that I'm aware of.
