I would rephrase and put "If nothing is specified" first, so the reader knows immediately what the point of this is. Also tab it in to be part of the `SupportedWatchpointTypes` block. https://github.com/llvm/llvm-project/pull/80376 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
