> Another big issue for Application Class systems IIRC -- unrelated to all this -- is that I don't think hardware implementing C can actually run binaries compiled without it. I believe this is incorrect? I believe RV{32,64}-with-C is simply a superset of RV{32,64}-without-C. Now I have only implemented RV32I, so I'm not that familiar with the C extension or other extensions for that matter, but in my digging through the various RV specs, I haven't found anything which suggests that implementing C requires breaking code compiled without the use of C. Do you have any details?

Nope, I was wrong! I was curious about a reference and went digging, and I was misremembering the details of a particular Linux-class system that didn't implement C (Shakti), so they needed an entirely new set of binary packages from distros to support them. Wish I could use strike-outs here, but oh well.

  No harm in emailing dang asking for a feature request. hn@ycombinator.com Perhaps if enough people asked for it then the <s> markdown equiv could be added ~~ in some apps.
