Izaron added a comment. libc++ doesn't support constexpr-related patches from C++20 in `<complex>`: see issue https://github.com/llvm/llvm-project/issues/55370
I reviewed the code in `<complex>` and found out that since we use a dozen of math functions, we need to support more constexpr builtin math function. I implemented constexpr versions for five functions. This will be enough to implement a 2017 paper: https://www.open-std.org/JTC1/SC22/WG21/docs/papers/2017/p0415r1.html (in a new pull request) (Also there is a 2019 paper with more constexpr functions for `<complex>`: https://www.open-std.org/JTC1/SC22/WG21/docs/papers/2019/p1383r0.pdf) Also builtin implementations will be useful for new C++23 constexpr functions: for example https://en.cppreference.com/w/cpp/numeric/math/scalbn Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D134136/new/ https://reviews.llvm.org/D134136 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
