2017-06-12Finish implementing P0426R1 "Constexpr for std::char_traits" for C++17Pedro Alves1-3/+2
As discussed in PR c++/80265 ("__builtin_{memcmp,memchr,strlen} are not usable in constexpr functions"), use __builtin_constant_p to tell whether we can defer to a constexpr algorithm. I used __always_inline__ just to be thorough. It isn't really really necessary as far as I could determine. Changes like these: if (__n == 0) return 0; - return wmemcmp(__s1, __s2, __n); + else + return wmemcmp(__s1, __s2, __n); are necessary otherwise G++ complains that we're calling a non-constexpr function, which looks like a a manifestation of PR67026 to me. libstdc++-v3: 2017-06-12 Pedro Alves <palves@redhat.com> * doc/xml/manual/status_cxx2017.xml: Update C++17 constexpr char_traits status. * doc/html/*: Regenerate. * include/bits/char_traits.h (_GLIBCXX_ALWAYS_INLINE): Define if not already defined.
