New module
|
|
^^^^^^^^^^
|
|
- New module `llvmlibc`.
|
|
|
|
This module contains checks related to the LLVM-libc coding standards.
|
|
|
|
New checks
|
|
^^^^^^^^^^
|
|
|
|
- New :doc:`bugprone-misplaced-pointer-arithmetic-in-alloc
|
|
<clang-tidy/checks/bugprone-misplaced-pointer-arithmetic-in-alloc>` check.
|
|
|
|
Finds cases where an integer expression is added to or subtracted from the
|
|
result of a memory allocation function (``malloc()``, ``calloc()``,
|
|
``realloc()``, ``alloca()``) instead of its argument.
|
|
|
|
- New :doc:`bugprone-reserved-identifier
|
|
<clang-tidy/checks/bugprone-reserved-identifier>` check.
|
|
|
|
Checks for usages of identifiers reserved for use by the implementation.
|
|
|
|
- New :doc:`bugprone-suspicious-include
|
|
<clang-tidy/checks/bugprone-suspicious-include>` check.
|
|
|
|
Finds cases where an include refers to what appears to be an implementation
|
|
file, which often leads to hard-to-track-down ODR violations, and diagnoses
|
|
them.
|
|
|
|
- New :doc:`cert-oop57-cpp
|
|
<clang-tidy/checks/cert-oop57-cpp>` check.
|
|
|
|
Flags use of the `C` standard library functions ``memset``, ``memcpy`` and
|
|
``memcmp`` and similar derivatives on non-trivial types.
|
|
|
|
- New :doc:`llvmlibc-restrict-system-libc-headers
|
|
<clang-tidy/checks/llvmlibc-restrict-system-libc-headers>` check.
|
|
|
|
Finds includes of system libc headers not provided by the compiler within
|
|
llvm-libc implementations.
|
|
|
|
- New :doc:`objc-dealloc-in-category
|
|
<clang-tidy/checks/objc-dealloc-in-category>` check.
|
|
|
|
Finds implementations of -dealloc in Objective-C categories.
|
|
|
|
- New :doc:`misc-no-recursion
|
|
<clang-tidy/checks/misc-no-recursion>` check.
|
|
|
|
Finds recursive functions and diagnoses them.
|
|
|
|
New check aliases
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
- New alias :doc:`cert-dcl37-c
|
|
<clang-tidy/checks/cert-dcl37-c>` to
|
|
:doc:`bugprone-reserved-identifier
|
|
<clang-tidy/checks/bugprone-reserved-identifier>` was added.
|
|
|
|
- New alias :doc:`cert-dcl51-cpp
|
|
<clang-tidy/checks/cert-dcl51-cpp>` to
|
|
:doc:`bugprone-reserved-identifier
|
|
<clang-tidy/checks/bugprone-reserved-identifier>` was added.
|
|
|
|
Changes in existing checks
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
- Improved :doc:`readability-qualified-auto
|
|
<clang-tidy/checks/readability-qualified-auto>` check now supports a
|
|
`AddConstToQualified` to enable adding ``const`` qualifiers to variables
|
|
typed with ``auto *`` and ``auto &``.
|
|
|
|
- Improved :doc:`readability-redundant-string-init
|
|
<clang-tidy/checks/readability-redundant-string-init>` check now supports a
|
|
`StringNames` option enabling its application to custom string classes. The
|
|
check now detects in class initializers and constructor initializers which
|
|
are deemed to be redundant.
|
|
|
|
- Checks supporting the ``HeaderFileExtensions`` flag now support ``;`` as a
|
|
delimiter in addition to ``,``, with the latter being deprecated as of this
|
|
release. This simplifies how one specifies the options on the command line:
|
|
``--config="{CheckOptions: [{ key: HeaderFileExtensions, value: h;;hpp;hxx }]}"``
|
|
|
|
Renamed checks
|
|
^^^^^^^^^^^^^^
|
|
|
|
- The 'fuchsia-restrict-system-headers' check was renamed to :doc:`portability-restrict-system-includes
|
|
<clang-tidy/checks/portability-restrict-system-includes>`
|
|
|
