  • Support for many previously unavailable features in freestanding mode, + thanks to Arsen Arsenović. For example, std::tuple is + now available for freestanding compilation. The freestanding subset + contains all the components made freestanding by + P1642, + but libstdc++ adds more components to the freestanding subset, + such as std::array and std::string_view. + Additionally, libstdc++ now respects the -ffreestanding + compiler option and so it is not necessary to build a separate + freestanding installation of libstdc++. Compiling with + -ffreestanding will restrict the available features to + the freestanding subset, even if libstdc++ was built as a full, hosted + implementation. +
