Jonathan Wakely bd81327b03 libstdc++: Fix feature test macros in <version> for freestanding ... Some C++17 and C++20 feature test macros are only defined in <version> for hosted builds, even though the features are supported for freestanding. All C++23 feature test macros are defined in <version> for freestanding, but most of the features are only supported for hosted. libstdc++-v3/ChangeLog: * include/std/version [!_GLIBCXX_HOSTED] (__cpp_lib_hardware_interference_size): Define for freestanding. (__cpp_lib_bit_cast): Likewise. (__cpp_lib_is_layout_compatible): Likewise. (__cpp_lib_is_pointer_interconvertible): Likewise. (__cpp_lib_adaptor_iterator_pair_constructor): Do not define for freestanding. (__cpp_lib_invoke_r): Likewise. (__cpp_lib_ios_noreplace): Likewise. (__cpp_lib_monadic_optional): Likewise. (__cpp_lib_move_only_function): Likewise. (__cpp_lib_spanstream): Likewise. (__cpp_lib_stacktrace): Likewise. (__cpp_lib_string_contains): Likewise. (__cpp_lib_string_resize_and_overwrite): Likewise. (__cpp_lib_to_underlying): Likewise.		2022-03-23 10:03:03 +00:00
