LLVM\n\n- [libc++ 14](https://releases.llvm.org/14.0.0/projects/libcxx/docs/ReleaseNotes.html) \"Floating-point support for std::to_chars support has been added. Thanks to Stephan T. Lavavej and Microsoft for providing their implementation to libc++.\"\n- [libc++15](https://releases.llvm.org/15.0.0/projects/libcxx/docs/ReleaseNotes.html) \"The functions std::from_chars and std::to_chars now have 128-bit integral support.\"\n- [P0067R3: Elementary string conversions #103643](https://github.com/llvm/llvm-project/issues/103643) is marked as closed.\n- [libc++16](https://releases.llvm.org/16.0.0/projects/libcxx/docs/ReleaseNotes.html) \"P2291R3 - Add Constexpr Modifiers to Functions to_chars and from_chars for Integral Types in \u003ccharconv\u003e Header\"\n\n2. Xcode support came in three folds.\n\n- [integral types](https://developer.apple.com/xcode/cpp/) - macOS 10.15 -\u003e Xcode ???\n- [floating-point types](https://developer.apple.com/xcode/cpp/) - macOS 13.3 -\u003e Xcode 14.3??\n- [Xcode 15](https://developer.apple.com/documentation/xcode-release-notes/xcode-15-release-notes) \"P2291R3 - Add constexpr modifiers to functions to_chars and from_chars for integral types in \u003ccharconv\u003e header\"\n\n## Note\n\nIt seems to me, LLVM15 finalized the implementation of P0067R3 without saying so in the release note because the following paper, P2291R3 `constexpr`-ification, gets implemented in LLVM16. Similar story for Xcode14 and Xcode 15. Need to be verified, though.\n\nThanks.","author":{"url":"https://github.com/ByunghoonKim","@type":"Person","name":"ByunghoonKim"},"datePublished":"2026-01-16T08:00:43.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/53/cppstat/issues/53"}
