+- ``-Wstrict-prototypes`` is a new warning that warns about non-prototype

+
+- ``-Wunguarded-availability`` is a new warning that warns about uses of new
+ APIs that were introduced in a system whose version is newer than the
+ deployment target version. A new Objective-C expression ``@available`` has
+ been introduced to perform system version checking at runtime. This warning
+ is off by default to prevent unexpected warnings in existing projects.
+ However, its less strict sibling ``-Wunguarded-availability-new`` is on by
+ default. It warns about unguarded uses of APIs only when they were introduced
+ in or after macOS 10.13, iOS 11, tvOS 11 or watchOS 4.
+
+- The ``-Wdocumentation`` warning now allows the use of ``\param`` and
+ ``\returns`` documentation directives in the documentation comments for
+ declarations with a function or a block pointer type.
+
+- The compiler no longer warns about unreachable ``__builtin_unreachable``
+ statements.

C Language Changes in Clang

+- Added near complete support for implicit scalar to vector conversion, a GNU
+ C/C++ language extension. With this extension, the following code is
+ considered valid:
+
+.. code-block:: c
+
+ typedef unsigned v4i32 __attribute__((vector_size(16)));
-...
+ v4i32 foo(v4i32 a) {
+ // Here 5 is implicitly casted to an unsigned value and replicated into a
+ // vector with as many elements as 'a'.
+ return a + 5;
+ }
+
+The implicit conversion of a scalar value to a vector value--in the context of
+a vector expression--occurs when:
-C11 Feature Support
-^^^^^^^^^^^^^^^^^^^
+- The type of the vector is that of a ``__attribute__((vector_size(size)))``
+ vector, not an OpenCL ``__attribute__((ext_vector_type(size)))`` vector type.
+
+- The scalar value can be casted to that of the vector element's type without
+ the loss of precision based on the type of the scalar and the type of the
+ vector's elements.
-...
+- For compile time constant values, the above rule is weakened to consider the
+ value of the scalar constant rather than the constant's type. However,
+ for compatibility with GCC, floating point constants with precise integral
+ representations are not implicitly converted to integer values.
+
+Currently the basic integer and floating point types with the following
+operators are supported: ``+``, ``/``, ``-``, ``*``, ``%``, ``>``, ``<``,
+``>=``, ``<=``, ``==``, ``!=``, ``&``, ``|``, ``^`` and the corresponding
+assignment operators where applicable.

C++ Language Changes in Clang
-----------------------------
-...
+- We expect this to be the last Clang release that defaults to ``-std=gnu++98``
+ when using the GCC-compatible ``clang++`` driver. From Clang 6 onwards we
+ expect to use ``-std=gnu++14`` or a later standard by default, to match the
+ behavior of recent GCC releases. Users are encouraged to change their build
+ files to explicitly specify their desired C++ standard.
+
+- Support for the C++17 standard has been completed. This mode can be enabled
+ using ``-std=c++17`` (the old flag ``-std=c++1z`` is still supported for
+ compatibility).
-C++1z Feature Support
-^^^^^^^^^^^^^^^^^^^^^
+- When targeting a platform that uses the Itanium C++ ABI, Clang implements a
+ `recent change to the ABI`__ that passes objects of class type indirectly if they
+ have a non-trivial move constructor. Previous versions of Clang only
+ considered the copy constructor, resulting in an ABI change in rare cases,
+ but GCC has already implemented this change for several releases.
+ This affects all targets other than Windows and PS4. You can opt out of this
+ ABI change with ``-fclang-abi-compat=4.0``.
-...
+- As mentioned in `C Language Changes in Clang`_, Clang's support for
+ implicit scalar to vector conversions also applies to C++. Additionally
+ the following operators are also supported: ``&&`` and ``||``.
