Improvements to clang-tidy¶

• New cppcoreguidelines-slicing check

  Flags slicing of member variables or vtable.

• New cppcoreguidelines-special-member-functions check

  Flags classes where some, but not all, special member functions are user-defined.

• The UseCERTSemantics option for the misc-move-constructor-init check has been removed as it duplicated the modernize-pass-by-value check.

• New misc-move-forwarding-reference check

  Warns when std::move is applied to a forwarding reference instead of std::forward.

• misc-pointer-and-integral-operation check was removed.

• New misc-string-compare check

  Warns about using compare to test for string equality or inequality.

• New misc-use-after-move check

  Warns if an object is used after it has been moved, without an intervening reinitialization.

• New cppcoreguidelines-no-malloc check warns if C-style memory management is used and suggests the use of RAII.

• modernize-make-unique and modernize-make-shared now handle calls to the smart pointer’s reset() method.

• The modernize-pass-by-value check now has a ValuesOnly option to only warn about parameters that are passed by value but not moved.

• The modernize-use-auto check now warns about variable declarations that are initialized with a cast, or by calling a templated function that behaves as a cast.

• The modernize-use-default check has been renamed to modernize-use-equals-default.

• New modernize-use-default-member-init check

  Converts a default constructor’s member initializers into default member initializers. Removes member initializers that are the same as a default member initializer.

• New modernize-use-equals-delete check

  Adds = delete to unimplemented private special member functions.

• New modernize-use-transparent-functors check

  Replaces uses of non-transparent functors with transparent ones where applicable.

• New mpi-buffer-deref check

  Flags buffers which are insufficiently dereferenced when passed to an MPI function call.

• New mpi-type-mismatch check

  Flags MPI function calls with a buffer type and MPI data type mismatch.

• New performance-inefficient-string-concatenation check

  Warns about the performance overhead arising from concatenating strings using the operator+, instead of operator+=.

• New performance-type-promotion-in-math-fn check

  Replaces uses of C-style standard math functions with double parameters and float arguments with an equivalent function that takes a float parameter.

• readability-container-size-empty check supports arbitrary containers with with suitable empty() and size() methods.

• New readability-misplaced-array-index check

  Warns when there is array index before the [] instead of inside it.

• New readability-non-const-parameter check

  Flags function parameters of a pointer type that could be changed to point to a constant type instead.

• New readability-redundant-declaration check

  Finds redundant variable and function declarations.

• New readability-redundant-function-ptr-dereference check

  Finds redundant function pointer dereferences.

• New readability-redundant-member-init check

  Flags member initializations that are unnecessary because the same default constructor would be called if they were not present.

• The readability-redundant-string-cstr check now warns about redundant calls to data() too.

• The google-explicit-constructor check now warns about conversion operators not marked explicit.

Fixed bugs:

• modernize-make-unique and modernize-make-shared Calling make_{unique|shared} from within a member function of a type with a private or protected constructor would be ill-formed.

Improvements to include-fixer¶

• Emacs integration was added.
