Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      New C++ papers available ➡️ http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/2018-02-pre-Jacksonville.htm … What'll make it to C+20? 😯

      I'm especially looking forward to "Signed Integers are Two’s Complement" for C++20. I know it'll be controversial 😬 http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0907r0.html …pic.twitter.com/pJSwUTStyk

      While we're at it, should C++ also specify:

      I just presented “signed integers are two’s complement” http://wg21.link/p0907r0  to a joint session of C++ numerics and undefined behavior groups! Broad support, but they want to keep UB on overflow (and have separate type or operator for wrap). I’ll update the paper 📝

      Not only is the C++ standards committee happy to make signed integers two's complement in C++20 with http://wg21.link/p0907 , the *C standards committee* voted to do the same thing for the next version of C! 🤯 I just have to write the wording. 🎉

      Does this mean conversions to signed types will be well-defined as modular reduction (e.g. (int)-1U==-1)?

      For C++ yes, for C they asked for more targeted papers for ~each bullet point I had in C++. I think some of the effects of the C++ wording wasn’t clear to the C committee, and I’m not there in person to explain. So maybe? I’ll certainly try to get the same effects as C++.pic.twitter.com/N5lS9UkrWt

      That sounds backwards. Signed to unsigned was always well-defined as modular reduction. It's conversion to signed where the value is out of range (whether because it's a larger unsigned value or a higher-rank signed value) that was "implementation-defined conversion or signal".

      OK second try with wording instead (some documentation out of date 🙂)pic.twitter.com/iWYjzHmYbM

      Should probably read "for *destination* integral types other than bool". Source type being bool is not exceptional, and it *is* outside the range of one integral type: signed bitfield of width 1. :-)

          Hmm, interesting point. The bool change came in late in writing the paper update, and I didn’t consider it here.pic.twitter.com/WWcPE8iYYy
