LLVM 14 does not have the analogous overall logic to ( /usr/include/c++/v1/__config ) : . . . # if __has_feature(experimental_library) # ifndef _LIBCPP_ENABLE_EXPERIMENTAL # define _LIBCPP_ENABLE_EXPERIMENTAL # endif # endif // Incomplete features get their own specific disabling flags. This makes it // easier to grep for target specific flags once the feature is complete. # if !defined(_LIBCPP_ENABLE_EXPERIMENTAL) && !defined(_LIBCPP_BUILDING_LIBRARY) # define _LIBCPP_HAS_NO_INCOMPLETE_FORMAT # define _LIBCPP_HAS_NO_INCOMPLETE_RANGES # endif . . . LLVM 14 just has ( /usr/include/c++/v1/__config_site ): /* #undef _LIBCPP_HAS_NO_INCOMPLETE_FORMAT */ /* #undef _LIBCPP_HAS_NO_INCOMPLETE_RANGES */ with no more-overall logic involved. --=20 You are receiving this mail because: You are on the CC list for the bug.=
