That's not the right (implied) question. The correct question is: > Will libc++pessimize existing (non-constexpr) users in C++03-through-C++17 > ***who are using old compilers*** in order to support new constexpr features > that come down the pike? And the answer to that is yes - eventually. I don't know when that will be, since the //new compilers// don't yet exist. That's the point of https://bugs.llvm.org/show_bug.cgi?id=25165.
