^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-- ``-Wpragma-pack`` is a new warning that warns in the following cases:
-
- - When a translation unit is missing terminating ``#pragma pack (pop)``
- directives.
-
- - When leaving an included file that changes the current alignment value,
- i.e. when the alignment before ``#include`` is different to the alignment
- after ``#include``.
-
- - ``-Wpragma-pack-suspicious-include`` (disabled by default) warns on an
- ``#include`` when the included file contains structures or unions affected by
- a non-default alignment that has been specified using a ``#pragma pack``
- directive prior to the ``#include``.
-
-- ``-Wobjc-messaging-id`` is a new, non-default warning that warns about
- message sends to unqualified ``id`` in Objective-C. This warning is useful
- for projects that would like to avoid any potential future compiler
- errors/warnings, as the system frameworks might add a method with the same
- selector which could make the message send to ``id`` ambiguous.
-
-- ``-Wtautological-compare`` now warns when comparing an unsigned integer and 0
- regardless of whether the constant is signed or unsigned."
-
-- ``-Wtautological-compare`` now warns about comparing a signed integer and 0
- when the signed integer is coerced to an unsigned type for the comparison.
- ``-Wsign-compare`` was adjusted not to warn in this case.
-
-- ``-Wtautological-constant-compare`` is a new warning that warns on
- tautological comparisons between integer variable of the type ``T`` and the
- largest/smallest possible integer constant of that same type.
-
-- For C code, ``-Wsign-compare``, ``-Wsign-conversion``,
- ``-Wtautological-constant-compare`` and
- ``-Wtautological-constant-out-of-range-compare`` were adjusted to use the
- underlying datatype of ``enum``.
-
-- ``-Wnull-pointer-arithmetic`` now warns about performing pointer arithmetic
- on a null pointer. Such pointer arithmetic has an undefined behavior if the
- offset is nonzero. It also now warns about arithmetic on a null pointer
- treated as a cast from integer to pointer (GNU extension).
-
-- ``-Wzero-as-null-pointer-constant`` was adjusted not to warn on null pointer
- constants that originate from system macros, except ``NULL`` macro.

Non-comprehensive list of changes in this release
-------------------------------------------------
-- Bitrig OS was merged back into OpenBSD, so Bitrig support has been
- removed from Clang/LLVM.
-
-- The default value of _MSC_VER was raised from 1800 to 1911, making it
- compatible with the Visual Studio 2015 and 2017 C++ standard library headers.
- Users should generally expect this to be regularly raised to match the most
- recently released version of the Visual C++ compiler.
-
-- clang now defaults to ``.init_array`` if no gcc installation can be found.
- If a gcc installation is found, it still prefers ``.ctors`` if the found
- gcc is older than 4.7.0.
-
-- The new builtin preprocessor macros ``__is_target_arch``,
- ``__is_target_vendor``, ``__is_target_os``, and ``__is_target_environment``
- can be used to to examine the individual components of the target triple.
+- ...
New Compiler Flags
------------------
-- --autocomplete was implemented to obtain a list of flags and its arguments. This is used for shell autocompletion.
-
-- The ``-fdouble-square-bracket-attributes`` and corresponding
- ``-fno-double-square-bracket-attributes`` flags were added to enable or
- disable [[]] attributes in any language mode. Currently, only a limited
- number of attributes are supported outside of C++ mode. See the Clang
- attribute documentation for more information about which attributes are
- supported for each syntax.
-
-- Added the ``-std=c17``, ``-std=gnu17``, and ``-std=iso9899:2017`` language
- mode flags for compatibility with GCC. This enables support for the next
- version of the C standard, expected to be published by ISO in 2018. The only
- difference between the ``-std=c17`` and ``-std=c11`` language modes is the
- value of the ``__STDC_VERSION__`` macro, as C17 is a bug fix release.

Attribute Changes in Clang
--------------------------
-- Clang now supports the majority of its attributes under both the GNU-style
- spelling (``__attribute((name))``) and the double square-bracket spelling
- in the ``clang`` vendor namespace (``[[clang::name]]``). Attributes whose
- syntax is specified by some other standard (such as CUDA and OpenCL
- attributes) continue to follow their respective specification.
-
-- Added the ``__has_c_attribute()`` builtin preprocessor macro which allows
- users to dynamically detect whether a double square-bracket attribute is
- supported in C mode. This attribute syntax can be enabled with the
- ``-fdouble-square-bracket-attributes`` flag.

C++ Language Changes in Clang

AST Matchers
------------
-The hasDeclaration matcher now works the same for Type and QualType and only
-ever looks through one level of sugaring in a limited number of cases.
-
-There are two main patterns affected by this:
-
-- qualType(hasDeclaration(recordDecl(...))): previously, we would look through
- sugar like TypedefType to get at the underlying recordDecl; now, we need
- to explicitly remove the sugaring:
- qualType(hasUnqualifiedDesugaredType(hasDeclaration(recordDecl(...))))
-
-- hasType(recordDecl(...)): hasType internally uses hasDeclaration; previously,
- this matcher used to match for example TypedefTypes of the RecordType, but
- after the change they don't; to fix, use:
-
-::
- hasType(hasUnqualifiedDesugaredType(
- recordType(hasDeclaration(recordDecl(...)))))
-
-- templateSpecializationType(hasDeclaration(classTemplateDecl(...))):
- previously, we would directly match the underlying ClassTemplateDecl;
- now, we can explicitly match the ClassTemplateSpecializationDecl, but that
- requires to explicitly get the ClassTemplateDecl:
-
-::
- templateSpecializationType(hasDeclaration(
- classTemplateSpecializationDecl(
