Runtime Library (libstdc++)

+ +
    +
  • + The libstdc++exp.a library now includes all the Filesystem TS + symbols from the libstdc++fs.a library. + The experimental symbols for the C++23 std::stacktrace class + are also in libstdc++exp.a, replacing the + libstdc++_libbacktrace.a library that GCC 13 provides. + This means that -lstdc++exp is the only library needed for + all experimental libstdc++ features. +
    • +
  • Improved experimental support for C++20, including: +
      +
    • std::chrono::parse.
      • +
    +
    • +
  • Improved experimental support for C++23, including: +
      +
    • The <stacktrace> header is supported by default. +
      • +
    • Formatters for std::thread::id and + std::stacktrace. +
      • +
    • Some range adaptors now support move-only types.
      • +
    +
    • +
  • Experimental support for C++26, including: +
      +
    • Native handles for filebuf, fstream, etc.
      • +
    • std::to_string now uses std::format.
      • +
    • Enhanced formatting of pointers with std::format.
      • +
    • Testable result types for <charconv> functions.
      • +
    +
    • +
  • Faster numeric conversions using std::to_string and + std::to_wstring. +
    • +
  • Updated parallel algorithms that are compatible with oneTBB.
    • +
  • std::numeric_limits<_Float32> and + std::numeric_limits<_Float64> are now defined + for all standard modes, not only for C++23. +
    • +
  • Using the std::setfill manipulator with + std::istream is deprecated. +
    • +
