| What's New in Extra Clang Tools 13.0.0? |
| ======================================= |

| infrastructure are described first, followed by tool-specific sections. |
| |
| Major New Features |
| ------------------ |
| |
| ... |
| |
| Improvements to clangd |
| ---------------------- |
| |

| |
| Improvements to clang-doc |

| |
| Improvements to clang-query |

| |
| Improvements to clang-tidy |
| -------------------------- |
| |
| - The `run-clang-tidy.py` helper script is now installed in `bin/` as |
| `run-clang-tidy`. It was previously installed in `share/clang/`. |
| |
| - Added command line option `--fix-notes` to apply fixes found in notes |
| attached to warnings. These are typically cases where we are less confident |
| the fix will have the desired effect. |
| |
| - libToolingCore and Clang-Tidy was refactored and now checks can produce |
| highlights (`^~~~~` under fragments of the source code) in diagnostics. |
| Existing and new checks in the future can be expected to start implementing |
| this functionality. |
| This change only affects the visual rendering of diagnostics, and does not |
| alter the behavior of generated fixes. |
| |
| New checks |
| ^^^^^^^^^^ |
| |
| - New :doc:`concurrency-thread-canceltype-asynchronous |
| <clang-tidy/checks/concurrency-thread-canceltype-asynchronous>` check. |
| |
| Finds ``pthread_setcanceltype`` function calls where a thread's cancellation |
| type is set to asynchronous. |
| |
| - New :doc:`altera-unroll-loops |
| <clang-tidy/checks/altera-unroll-loops>` check. |
| |
| Finds inner loops that have not been unrolled, as well as fully unrolled |
| loops with unknown loops bounds or a large number of iterations. |
| |
| - New :doc:`cppcoreguidelines-prefer-member-initializer |
| <clang-tidy/checks/cppcoreguidelines-prefer-member-initializer>` check. |
| |
| Finds member initializations in the constructor body which can be placed into |
| the initialization list instead. |
| |
| New check aliases |
| ^^^^^^^^^^^^^^^^^ |
| |
| - New alias :doc:`cert-pos47-c |
| <clang-tidy/checks/cert-pos47-c>` to |
| :doc:`concurrency-thread-canceltype-asynchronous |
| <clang-tidy/checks/concurrency-thread-canceltype-asynchronous>` was added. |
| |
| Changes in existing checks |
| ^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| |
| - Improved :doc:`bugprone-signal-handler |
| <clang-tidy/checks/bugprone-signal-handler>` check. |
| |
| Added an option to choose the set of allowed functions. |
| |
| - Improved :doc:`readability-uniqueptr-delete-release |
| <clang-tidy/checks/readability-uniqueptr-delete-release>` check. |
| |
| Added an option to choose whether to refactor by calling the ``reset`` member |
| function or assignment to ``nullptr``. |
| Added support for pointers to ``std::unique_ptr``. |
| |
| Removed checks |
| ^^^^^^^^^^^^^^ |
| |
| - The readability-deleted-default check has been removed. |
| |
| The clang warning `Wdefaulted-function-deleted |
| <https://clang.llvm.org/docs/DiagnosticsReference.html#wdefaulted-function-deleted>`_ |
| will diagnose the same issues and is enabled by default. |
