 Introduction
 ============

 This document contains the release notes for the Extra Clang Tools, part of the
 Clang release |release|. Here we describe the status of the Extra Clang Tools in
 some detail, including major improvements from the previous release and new
 feature work. All LLVM releases may be downloaded from the `LLVM releases web
 site <https://llvm.org/releases/>`_.

 For more information about Clang or LLVM, including information about
 the latest release, please see the `Clang Web Site <https://clang.llvm.org>`_ or
 the `LLVM Web Site <https://llvm.org>`_.

 Note that if you are reading this file from a Git checkout or the
 main Clang web page, this document applies to the *next* release, not
 the current one. To see the release notes for a specific release, please
 see the `releases page <https://llvm.org/releases/>`_.

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

 Some of the major new features and improvements to Extra Clang Tools are listed
 here. Generic improvements to Extra Clang Tools as a whole or to its underlying
 infrastructure are described first, followed by tool-specific sections.

 Major New Features
 ------------------

 Potentially Breaking Changes
 ----------------------------

 - Removed :program:`clang-tidy`'s global options `IgnoreMacros` and
   `StrictMode`, which were documented as deprecated since
   :program:`clang-tidy-20`. Users should use the check-specific options of the
   same name instead.

 - Renamed :program:`clang-tidy`'s option name of check
   :doc:`bugprone-easily-swappable-parameters
   <clang-tidy/checks/bugprone/easily-swappable-parameters>` from
   ``NamePrefixSuffixSilenceDissimilarityTreshold`` to
   ``NamePrefixSuffixSilenceDissimilarityThreshold``,
   correcting a spelling mistake.

 Improvements to clangd
 ----------------------

 Inlay hints
 ^^^^^^^^^^^

 Diagnostics
 ^^^^^^^^^^^

 Semantic Highlighting
 ^^^^^^^^^^^^^^^^^^^^^

 Compile flags
 ^^^^^^^^^^^^^

 Hover
 ^^^^^

 Code completion
 ^^^^^^^^^^^^^^^

 Code actions
 ^^^^^^^^^^^^

 - New ``Override pure virtual methods`` code action. When invoked on a class
   definition, this action automatically generates C++ ``override`` declarations
   for all pure virtual methods inherited from its base classes that have not yet
   been implemented. The generated method stubs prompts the user for the actual
   implementation. The overrides are intelligently grouped under their original
   access specifiers (e.g., ``public``, ``protected``), creating new access
   specifier blocks if necessary.

 Signature help
 ^^^^^^^^^^^^^^

 Cross-references
 ^^^^^^^^^^^^^^^^

 Objective-C
 ^^^^^^^^^^^

 Miscellaneous
 ^^^^^^^^^^^^^

 Improvements to clang-doc
 -------------------------

 Improvements to clang-query
 ---------------------------

 - Matcher queries interpreted by clang-query are now support trailing comma (,)
   in matcher arguments. Note that C++ still doesn't allow this in function
   arguments. So when porting a query to C++, remove all instances of trailing
   comma (otherwise C++ compiler will just complain about "expected expression").

 Improvements to clang-tidy
 --------------------------

 - The :program:`check_clang_tidy.py` tool now recognizes the ``-std`` argument
   when run over C files. If ``-std`` is not specified, it defaults to
   ``c99-or-later``.

 - :program:`clang-tidy` no longer attemps to analyze code from system headers
   by default, greatly improving performance. This behavior is disabled if the
   `SystemHeaders` option is enabled.

 - :program:`clang-tidy` now supports query based custom checks by `CustomChecks`
   configuration option.
   :doc:`Query Based Custom Check Document <clang-tidy/QueryBasedCustomChecks>`

 - The :program:`run-clang-tidy.py` and :program:`clang-tidy-diff.py` scripts
   now run checks in parallel by default using all available hardware threads.
   Both scripts display the number of threads being used in their output.

 - Improved :program:`run-clang-tidy.py` by adding a new option
   `enable-check-profile` to enable per-check timing profiles and print a
   report based on all analyzed files.

 - Improved documentation of the `-line-filter` command-line flag of
   :program:`clang-tidy` and :program:`run-clang-tidy.py`.

 - Improved :program:`clang-tidy` option `-quiet` by suppressing diagnostic
   count messages.

 - Improved :program:`clang-tidy` by not crashing when an empty `directory`
   field is used in a compilation database; the current working directory
   will be used instead, and an error message will be printed.

 - Removed :program:`clang-tidy`'s global options `IgnoreMacros` and
   `StrictMode`, which were documented as deprecated since
   :program:`clang-tidy-20`. Users should use the check-specific options of the
   same name instead.

 - Improved :program:`run-clang-tidy.py` and :program:`clang-tidy-diff.py`
   scripts by adding the `-hide-progress` option to suppress progress and
   informational messages.

 New checks
 ^^^^^^^^^^

 - New :doc:`bugprone-invalid-enum-default-initialization
   <clang-tidy/checks/bugprone/invalid-enum-default-initialization>` check.

   Detects default initialization (to 0) of variables with ``enum`` type where
   the enum has no enumerator with value of 0.

 - New :doc:`bugprone-derived-method-shadowing-base-method
   <clang-tidy/checks/bugprone/derived-method-shadowing-base-method>` check.

   Finds derived class methods that shadow a (non-virtual) base class method.

 - New :doc:`cppcoreguidelines-pro-bounds-avoid-unchecked-container-access
   <clang-tidy/checks/cppcoreguidelines/pro-bounds-avoid-unchecked-container-access>`
   check.

   Finds calls to ``operator[]`` in STL containers and suggests replacing them
   with safe alternatives.

 - New :doc:`google-runtime-float
   <clang-tidy/checks/google/runtime-float>` check.

   Finds uses of ``long double`` and suggests against their use due to lack of
   portability.

 - New :doc:`llvm-mlir-op-builder
   <clang-tidy/checks/llvm/use-new-mlir-op-builder>` check.

   Checks for uses of MLIR's old/to be deprecated ``OpBuilder::create<T>`` form
   and suggests using ``T::create`` instead.

 - New :doc:`llvm-use-ranges
   <clang-tidy/checks/llvm/use-ranges>` check.

   Finds calls to STL library iterator algorithms that could be replaced with
   LLVM range-based algorithms from ``llvm/ADT/STLExtras.h``.

 - New :doc:`misc-override-with-different-visibility
   <clang-tidy/checks/misc/override-with-different-visibility>` check.

   Finds virtual function overrides with different visibility than the function
   in the base class.

 New check aliases
 ^^^^^^^^^^^^^^^^^

 - Renamed :doc:`cert-err34-c <clang-tidy/checks/cert/err34-c>` to
   :doc:`bugprone-unchecked-string-to-number-conversion
   <clang-tidy/checks/bugprone/unchecked-string-to-number-conversion>`
   keeping initial check as an alias to the new one.

 Changes in existing checks
 ^^^^^^^^^^^^^^^^^^^^^^^^^^

   <clang-tidy/checks/bugprone/sizeof-expression>` check by fixing
   a crash on ``sizeof`` of an array of dependent type.

 - Improved :doc:`bugprone-tagged-union-member-count
   <clang-tidy/checks/bugprone/tagged-union-member-count>` by fixing a false
   positive when enums or unions from system header files or the ``std``
   namespace are treated as the tag or the data part of a user-defined
   tagged union respectively.

 - Improved :doc:`bugprone-unchecked-optional-access
   <clang-tidy/checks/bugprone/unchecked-optional-access>` check by supporting
   ``NullableValue::makeValue`` and ``NullableValue::makeValueInplace`` to

   <clang-tidy/checks/misc/header-include-cycle>` check performance.

 - Improved :doc:`modernize-avoid-c-arrays
   <clang-tidy/checks/modernize/avoid-c-arrays>` to not diagnose array types
   which are part of an implicit instantiation of a template.

 - Improved :doc:`modernize-use-constraints
   <clang-tidy/checks/modernize/use-constraints>` check by fixing a crash on
   uses of non-standard ``enable_if`` with a signature different from
   ``std::enable_if`` (such as ``boost::enable_if``).

 - Improved :doc:`modernize-use-designated-initializers
   <clang-tidy/checks/modernize/use-designated-initializers>` check to
   suggest using designated initializers for aliased aggregate types.

   detection in container's method except ``empty``.

 - Improved :doc:`readability-identifier-naming
   <clang-tidy/checks/readability/identifier-naming>` check by ignoring
   declarations and macros in system headers. The documentation is also improved
