hmm, that's an interesting direction. We were discussing this internally, and we were outlining some ideas along these lines, but I think you've articulated this quite a bit better than we have so far. I really like this idea of a "no-builtins" world, and transitioning the IR. I also find the idea of "partial-builtins" to be quite compelling, though I agree the usefulness maybe limited to scenarios where you're supplying a libc to LTO. Given that we're often dealing w/ kernel and embedded code, though, I think this is worth exporing more. I plan to discuss this a bit more w/ my team today, and hopefully write up something a bit more cogent than my earlier rambling. @mysterymath and @frobtech may have more to say as well.
