URL: https://github.com/llvm/llvm-project/commit/3f526756827fecd80111d1f065b879d292518480 DIFF: https://github.com/llvm/llvm-project/commit/3f526756827fecd80111d1f065b879d292518480.diff LOG: [clang] Update C++ DR status page (#205342) The post-Brno draft will not be out for three more weeks, but Brno updates for Core issues statuses are already trickling in. Notably, [CWG507](https://cplusplus.github.io/CWG/issues/507.html) "Ambiguity with built-in binary operator candidates for class object convertible to built-in type", which used to be marked as a duplicate of [CWG260](https://cplusplus.github.io/CWG/issues/260.html) "User-defined conversions and built-in `operator=`", is open again, presumably because it contains an example that goes beyond the scope of CWG260. Relatively recent CWG thread that might be related (WG21 access required): [link](https://lists.isocpp.org/core/2025/08/18478.php).
