_HAS_CXX17 indicates whether MSVC's STL is in C++17 mode. In MSVC there's a distinction between CRT headers like stdlib.h and STL headers like cstdlib. Only the STL headers drag in yvals.h, our internal STL-wide header that defines internal macros like _HAS_CXX17. _HAS_CXX17 is an MSVC STL library macro, unconditionally defined. We centralize everything on this, because we have to ask different questions to determine whether C1XX, EDG, or Clang is in 14 or 17 mode, and we additionally permit users to override the detection in one way (it's okay to ask for 17 from the compiler, but only 14 from the libs, at least for the moment; only noexcept in the type system will give us a headache). As this header is for testing MSVC's STL, we can assume _HAS_CXX17 is defined. Fixes D32726. llvm-svn: 302104 |
