[libc++] Replace 'tags' in CSV status pages by inline notes (#105581) This patch replaces 'tags' in the CSV status pages by inline notes that optionally describe more details about the paper/LWG issue. Tags were not really useful anymore because we have a vastly superior tagging system via Github issues, and keeping the tags up-to-date between CSV files and Github is going to be really challenging. This patch also adds support for encoding custom notes in the CSV files via Github issues. To encode a note in the CSV file, the body (initial description) of a Github issue can be edited to contain the following markers: BEGIN-RST-NOTES text that will be added as a note in the RST END-RST-NOTES Amongst other things, this solves the problem of conveying that a paper has been implemented as a DR, and it gives a unified way to add notes to the status pages from Github.

[libc++] Replace 'tags' in CSV status pages by inline notes (#105581) This patch replaces 'tags' in the CSV status pages by inline notes that optionally describe more details about the paper/LWG issue. Tags were not really useful anymore because we have a vastly superior tagging system via Github issues, and keeping the tags up-to-date between CSV files and Github is going to be really challenging. This patch also adds support for encoding custom notes in the CSV files via Github issues. To encode a note in the CSV file, the body (initial description) of a Github issue can be edited to contain the following markers: BEGIN-RST-NOTES text that will be added as a note in the RST END-RST-NOTES Amongst other things, this solves the problem of conveying that a paper has been implemented as a DR, and it gives a unified way to add notes to the status pages from Github.

[libc++][chono] Use hidden friends for leap_second comparison. (#104713) The function template<class Duration> requires three_way_comparable_with<sys_seconds, sys_time<Duration>> constexpr auto operator<=>(const leap_second& x, const sys_time<Duration>& y) noexcept; Has a recursive constrained. This caused an infinite loop in GCC and is now hit by https://github.com/llvm/llvm-project/pull/102857. A fix would be to make this function a hidden friend, this solution is propsed in LWG4139. For consistency all comparisons are made hidden friends. Since the issue causes compilation failures no additional test are needed. Fixes: https://github.com/llvm/llvm-project/issues/104700
