I'm mostly interested in whether `__declspec(nothrow)` is intended to be part of the type system in the same way `noexcept` specifiers are. @erichkeane -- can you see whether `__attribute__((nothrow))` is part of the type system as far as GCC is concerned (in C++17 mode, assuming GCC has implemented that functionality already)? https://reviews.llvm.org/D38209 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
