<p>I have no objection to the end of March timeline for C++14. This will still be a bit of a pain for us, but at the moment, I think we're on target for the previously communicated dates. I'll note that having a lot of warning for this (Nov to March) was
a key factor in my no objection response. :)<o:p></o:p></p>

<p class="MsoNormal">I’m only proposing that we migrate to C++14 for now. If you want to propose C++17, please do the work required by the policy. In particular, document which toolchains this would require, and what features you’d unlock. As per policy, I
want to start soft-errors when building LLVM 8, so that LLVM 9 can use more than C++11.<o:p></o:p></p>

<p class="MsoNormal">At the LLVM dev meeting BoF, the room already agreed to move past C++11. Late March 2019 was proposed as a time when we’d start migrating, pending large contributors’ readiness. I’m sticking to that timeline, we’ll see if everyone is ready
at the end of March. I nonetheless want to get the soft-errors into the LLVM 8 branch so that we give a sufficient heads-up to developers who only compile releases.<o:p></o:p></p>
