Improvements to clang-tidy
|
|
--------------------------
|
|
|
|
- New module `abseil` for checks related to the `Abseil <https://abseil.io>`_
|
|
library.
|
|
|
|
- New module ``portability``.
|
|
|
|
- New module ``zircon`` for checks related to Fuchsia's Zircon kernel.
|
|
|
|
- New :doc:`bugprone-throw-keyword-missing
|
|
<clang-tidy/checks/bugprone-throw-keyword-missing>` check
|
|
|
|
Diagnoses when a temporary object that appears to be an exception is
|
|
constructed but not thrown.
|
|
|
|
- New :doc:`bugprone-unused-return-value
|
|
<clang-tidy/checks/bugprone-unused-return-value>` check
|
|
|
|
Warns on unused function return values.
|
|
|
|
- New :doc:`cppcoreguidelines-avoid-goto
|
|
<clang-tidy/checks/cppcoreguidelines-avoid-goto>` check
|
|
|
|
The usage of ``goto`` for control flow is error prone and should be replaced
|
|
with looping constructs. Every backward jump is rejected. Forward jumps are
|
|
only allowed in nested loops.
|
|
|
|
- New :doc:`fuchsia-multiple-inheritance
|
|
<clang-tidy/checks/fuchsia-multiple-inheritance>` check
|
|
|
|
Warns if a class inherits from multiple classes that are not pure virtual.
|
|
|
|
- New :doc:`abseil-string-find-startswith
|
|
<clang-tidy/checks/abseil-string-find-startswith>` check
|
|
|
|
Checks whether a ``std::string::find()`` result is compared with 0, and
|
|
suggests replacing with ``absl::StartsWith()``.
|
|
|
|
- New :doc:`fuchsia-statically-constructed-objects
|
|
<clang-tidy/checks/fuchsia-statically-constructed-objects>` check
|
|
|
|
Warns if global, non-trivial objects with static storage are constructed,
|
|
unless the object is statically initialized with a ``constexpr`` constructor
|
|
or has no explicit constructor.
|
|
|
|
- New :doc:`fuchsia-trailing-return
|
|
<clang-tidy/checks/fuchsia-trailing-return>` check
|
|
|
|
Functions that have trailing returns are disallowed, except for those
|
|
using ``decltype`` specifiers and lambda with otherwise unutterable
|
|
return types.
|
|
|
|
- New :doc:`hicpp-multiway-paths-covered
|
|
<clang-tidy/checks/hicpp-multiway-paths-covered>` check
|
|
|
|
Checks on ``switch`` and ``if`` - ``else if`` constructs that do not cover all possible code paths.
|
|
|
|
- New :doc:`modernize-use-uncaught-exceptions
|
|
<clang-tidy/checks/modernize-use-uncaught-exceptions>` check
|
|
|
|
Finds and replaces deprecated uses of ``std::uncaught_exception`` to
|
|
``std::uncaught_exceptions``.
|
|
|
|
- New :doc:`portability-simd-intrinsics
|
|
<clang-tidy/checks/portability-simd-intrinsics>` check
|
|
|
|
Warns or suggests alternatives if SIMD intrinsics are used which can be replaced by
|
|
``std::experimental::simd`` operations.
|
|
|
|
- New :doc:`zircon-temporary-objects
|
|
<clang-tidy/checks/zircon-temporary-objects>` check
|
|
|
|
Warns on construction of specific temporary objects in the Zircon kernel.
