Based on this it appears that for the llvm16 __cpp_lib_... feature test macros vs. the existing main Freebsd ones: If fully adopted, the libc++ would go from having undefined status to having the modern values for: __cpp_lib_constexpr_complex __cpp_lib_constexpr_vector __cpp_lib_memory_resource __cpp_lib_polymorphic_allocator __cpp_lib_source_location Also, __cpp_lib_ranges would go from undefined to 202106 . C++20 also has a later 202110 . C++23 has 3 later values, the last being 202211 . (I'm generally omitting the L suffixes in my materials.) It does not appear that any other __cpp_lib_... macros would change values. These notes are based on using -std=3Dc++20 . Other notes: __cpp_lib_int_pow2 in my prior note turned out to be from it not being in the sort order position for the join operation in the material that I copied/genrated and processed. It is in fact up to date in main FreeBSD. --=20 You are receiving this mail because: You are on the CC list for the bug.=
