<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Vlad Serebrennikov (Endilll) <details> <summary>Changes</summary> Following [recent discussion](http://lists.isocpp.org/core/2025/10/18637.php) on CWG reflector, `cwg_index.html` now contains section number and stable name of that section for each Core issue. I thought that this would be a useful information to have on our C++ DR status page for that handful of experts who actually open it, so here we are. This PR consists of 3 parts: 1. Rewrite of a small routine that parses `cwg_index.html` from splits and indicies to a single regular expression with named groups, adding section information. 2. Changes to the rest of the `make_cxx_dr_status` to accommodate for the first part. 3. Regenerated `cxx_dr_status.html`. Ideally this PR would only add lines to `cxx_dr_status.html`, but previously we've been leaving some newlines in issue titles (which never affected how this page is rendered), which are now properly replaced with whitespaces — hence a couple of deletions in that file. --- Patch is 1.01 MiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/165749.diff 2 Files
