 Improvements to clang-tidy
 --------------------------
 
-- New global configuration file options `HeaderFileExtensions` and
-  `ImplementationFileExtensions`, replacing the check-local options of the
-  same name.
-
-- Support specifying `Checks` as a YAML list in the `.clang-tidy` configuration
-  file.
-
-- Fix a potential crash when using the `--dump-config` option.
-
-- Support specifying `SystemHeaders` in the `.clang-tidy` configuration file,
-  with the same functionality as the command-line option `--system-headers`.
-
-- `WarningsAsErrors` (`--warnings-as-errors=`) no longer promotes unlisted
-  warnings to errors. Only the warnings listed in `Checks` (`--checks=`) will
-  be promoted to errors. For custom error promotion, use `-Werror=<warning>`
-  on the compiler command-line, irrespective of `Checks` (`--checks=`) settings.
-
-- Fixed an issue where compiler warnings couldn't be suppressed using
-  `-Wno-<warning>` under C++20 and above.
-

 C/C++ Language Potentially Breaking Changes
 -------------------------------------------
-- Indirect edges of asm goto statements under certain circumstances may now be
-  split. In previous releases of clang, that means for the following code the
-  two inputs may have compared equal in the inline assembly.  This is no longer
-  guaranteed (and necessary to support outputs along indirect edges, which is
-  now supported as of this release). This change is more consistent with the
-  behavior of GCC.

-
-- ``__builtin_object_size`` and ``__builtin_dynamic_object_size`` now add the
-  ``sizeof`` the elements specified in designated initializers of flexible
-  array members for structs that contain them. This change is more consistent
-  with the behavior of GCC.
 
 C++ Specific Potentially Breaking Changes
 -----------------------------------------
-- Clang won't search for coroutine_traits in std::experimental namespace any more.
-  Clang will only search for std::coroutine_traits for coroutines then.
-- Clang no longer allows dereferencing of a ``void *`` as an extension. Clang 16
-  converted this to a default-error as ``-Wvoid-ptr-dereference``, as well as a
-  SFINAE error. This flag is still valid however, as it disables the equivalent
-  warning in C.
 
 ABI Changes in This Version
 ---------------------------
-- A bug in evaluating the ineligibility of some special member functions has been fixed. This can
-  make some classes trivially copyable that were not trivially copyable before. (`#62555 <https://github.com/llvm/llvm-project/issues/62555>`_)
 
 What's New in Clang |release|?
 ==============================
@@ -79,1032 +56,128 @@ sections with improvements to Clang's support for those languages.
 
 C++ Language Changes
 --------------------
-- Improved ``-O0`` code generation for calls to ``std::forward_like``. Similarly to
-  ``std::move, std::forward`` et al. it is now treated as a compiler builtin and implemented
-  directly rather than instantiating the definition from the standard library.
-- Implemented `CWG2518 <https://wg21.link/CWG2518>`_ which allows ``static_assert(false)``
-  to not be ill-formed when its condition is evaluated in the context of a template definition.
-- Declaring namespace std to be an inline namespace is now prohibited, `[namespace.std]p7`.
 
 C++20 Feature Support
 ^^^^^^^^^^^^^^^^^^^^^
-- Implemented the rule introduced by `CA104 <https://wg21.link/P2103R0>`_  for comparison of
-  constraint-expressions. Improved support for out-of-line definitions of constrained templates.
-  This fixes:
-  `#49620 <https://github.com/llvm/llvm-project/issues/49620>`_,
-  `#60231 <https://github.com/llvm/llvm-project/issues/60231>`_,
-  `#61414 <https://github.com/llvm/llvm-project/issues/61414>`_,
-  `#61809 <https://github.com/llvm/llvm-project/issues/61809>`_.
-- Lambda templates with a requires clause directly after the template parameters now parse
-  correctly if the requires clause consists of a variable with a dependent type.
-  (`#61278 <https://github.com/llvm/llvm-project/issues/61278>`_)
-- Announced C++20 Coroutines is fully supported on all targets except Windows, which
-  still has some stability and ABI issues.
-- Downgraded use of a reserved identifier in a module export declaration from
-  an error to a warning under the ``-Wreserved-module-identifier`` warning
-  group. This warning is enabled by default. This addresses `#61446
-  <https://github.com/llvm/llvm-project/issues/61446>`_ and allows easier
-  building of standard modules. This diagnostic may be strengthened into an
-  error again in the future once there is a less fragile way to mark a module
-  as being part of the implementation rather than a user module.
-- Clang now implements `[temp.deduct]p9`. Substitution failures inside lambdas from
-  unevaluated contexts will be surfaced as errors. They were previously handled as
-  SFINAE.
-- Clang now supports `requires cplusplus20` for module maps.
-- Implemented missing parts of `P2002R1: Consistent comparison operators <https://wg21.link/P2002R1>`_
-- Clang now defines `__cpp_consteval` macro.
-- Implemented `P1816R0: <https://wg21.link/p1816r0>`_ and `P2082R1: <https://wg21.link/p2082r1>`_,
-  which allows CTAD for aggregates.
 
 C++23 Feature Support
 ^^^^^^^^^^^^^^^^^^^^^
 
-- Implemented `P2036R3: Change scope of lambda trailing-return-type <https://wg21.link/P2036R3>`_
-  and `P2579R0 Mitigation strategies for P2036 <https://wg21.link/P2579R0>`_.
-  These proposals modify how variables captured in lambdas can appear in trailing return type
-  expressions and how their types are deduced therein, in all C++ language versions.
-- Implemented partial support for `P2448R2: Relaxing some constexpr restrictions <https://wg21.link/p2448r2>`_
-  Explicitly defaulted functions no longer have to be constexpr-compatible but merely constexpr suitable.
-  We do not support outside of defaulted special memeber functions the change that constexpr functions no
-  longer have to be constexpr compatible but rather support a less restricted requirements for constexpr
-  functions. Which include allowing non-literal types as return values and parameters, allow calling of
-  non-constexpr functions and constructors.
-- Clang now supports `requires cplusplus23` for module maps.
-- Implemented `P2564R3: consteval needs to propagate up <https://wg21.link/P2564R3>`_.
-
 C++2c Feature Support
 ^^^^^^^^^^^^^^^^^^^^^
-- Compiler flags ``-std=c++2c`` and ``-std=gnu++2c`` have been added for experimental C++2c implementation work.
-- Implemented `P2738R1: constexpr cast from void* <https://wg21.link/P2738R1>`_.
-- Partially implemented `P2361R6: Unevaluated strings <https://wg21.link/P2361R6>`_.
-  The changes to attributes declarations are not part of this release.
-- Implemented `P2741R3: user-generated static_assert messages  <https://wg21.link/P2741R3>`_.
 
 Resolutions to C++ Defect Reports
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-- Implemented `DR2397 <https://wg21.link/CWG2397>`_ which allows ``auto`` specifier for pointers
-  and reference to arrays.
-- Implemented `CWG2521 <https://wg21.link/CWG2521>`_ which reserves using ``__`` in user-defined
-  literal suffixes and deprecates literal operator function declarations using an identifier.
-  Taught ``-Wuser-defined-literals`` for the former, on by default, and added
-  ``-Wdeprecated-literal-operator`` for the latter, off by default for now.
-
-  .. code-block:: c++
-
-    // What follows is warned by -Wuser-defined-literals
-    // albeit "ill-formed, no diagnostic required".
-    // Its behavior is undefined, [reserved.names.general]p2.
-    string operator ""__i18n(const char*, std::size_t);
-
-    // Assume this declaration is not in the global namespace.
-    // -Wdeprecated-literal-operator diagnoses the extra space.
-    string operator "" _i18n(const char*, std::size_t);
-    //                ^ an extra space
 
 C Language Changes
 ------------------
-- Support for outputs from asm goto statements along indirect edges has been
-  added. (`#53562 <https://github.com/llvm/llvm-project/issues/53562>`_)
-- Fixed a bug that prevented initialization of an ``_Atomic``-qualified pointer
-  from a null pointer constant.
-- Fixed a bug that prevented casting to an ``_Atomic``-qualified type.
-  (`#39596 <https://github.com/llvm/llvm-project/issues/39596>`_)
-- Added an extension to ``_Generic`` which allows the first operand to be a
-  type rather than an expression. The type does not undergo any conversions,
-  which makes this feature suitable for matching qualified types, incomplete
-  types, and function or array types.
-
-  .. code-block:: c
-
-    const int i = 12;
-    _Generic(i, int : 0, const int : 1); // Warns about unreachable code, the
-                                         // result is 0, not 1.
-    _Generic(typeof(i), int : 0, const int : 1); // Result is 1, not 0.
 
 C2x Feature Support
 ^^^^^^^^^^^^^^^^^^^
-- Implemented the ``unreachable`` macro in freestanding ``<stddef.h>`` for
-  `WG14 N2826 <https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2826.pdf>`_
-
-- Removed the ``ATOMIC_VAR_INIT`` macro in C2x and later standards modes, which
-  implements `WG14 N2886 <https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2886.htm>`_
-
-- Implemented `WG14 N2934 <https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2934.pdf>`_
-  which introduces the ``bool``, ``static_assert``, ``alignas``, ``alignof``,
-  and ``thread_local`` keywords in C2x.
-
-- Implemented `WG14 N2900 <https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2900.htm>`_
-  and `WG14 N3011 <https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3011.htm>`_
-  which allows for empty braced initialization in C.
-
-  .. code-block:: c
-
-    struct S { int x, y } s = {}; // Initializes s.x and s.y to 0
-
-  As part of this change, the ``-Wgnu-empty-initializer`` warning group was
-  removed, as this is no longer a GNU extension but a C2x extension. You can
-  use ``-Wno-c2x-extensions`` to silence the extension warning instead.
-
-- Updated the implementation of
-  `WG14 N3042 <https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3042.htm>`_
-  based on decisions reached during the WG14 CD Ballot Resolution meetings held
-  in Jan and Feb 2023. This should complete the implementation of ``nullptr``
-  and ``nullptr_t`` in C. The specific changes are:
-
-  .. code-block:: c
-
-    void func(nullptr_t);
-    func(0); // Previously required to be rejected, is now accepted.
-    func((void *)0); // Previously required to be rejected, is now accepted.
-
-    nullptr_t val;
-    val = 0; // Previously required to be rejected, is now accepted.
-    val = (void *)0; // Previously required to be rejected, is now accepted.
-
-    bool b = nullptr; // Was incorrectly rejected by Clang, is now accepted.
-
-- Implemented `WG14 N3124 <https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3124.pdf>_`,
-  which allows any universal character name to appear in character and string literals.
-
 
 Non-comprehensive list of changes in this release
 -------------------------------------------------
-- Clang now saves the address of ABI-indirect function parameters on the stack,
-  improving the debug information available in programs compiled without
-  optimizations.
-- Clang now supports ``__builtin_nondeterministic_value`` that returns a
-  nondeterministic value of the same type as the provided argument.
-- Clang now supports ``__builtin_FILE_NAME()`` which returns the same
-  information as the ``__FILE_NAME__`` macro (the presumed file name
-  from the invocation point, with no path components included).
-- Clang now supports ``__builtin_assume_separate_storage`` that indicates that
-  its arguments point to objects in separate storage allocations.
-- Clang now supports expressions in ``#pragma clang __debug dump``.
-- Clang now supports declaration of multi-dimensional arrays with
-  ``__declspec(property)``.
-- A new builtin type trait ``__is_trivially_equality_comparable`` has been added,
-  which checks whether comparing two instances of a type is equivalent to
-  ``memcmp(&lhs, &rhs, sizeof(T)) == 0``.
-- Clang now ignores null directives outside of the include guard when deciding
-  whether a file can be enabled for the multiple-include optimization.
-- Clang now support ``__builtin_FUNCSIG()`` which returns the same information
-  as the ``__FUNCSIG__`` macro (available only with ``-fms-extensions`` flag).
-  This fixes (`#58951 <https://github.com/llvm/llvm-project/issues/58951>`_).
-- Clang now supports the `NO_COLOR <https://no-color.org/>`_ environment
-  variable as a way to disable color diagnostics.
-- Clang now supports ``__builtin_isfpclass``, which checks if the specified
-  floating-point value falls into any of the specified data classes.
-- Added ``__builtin_elementwise_round`` for  builtin for floating
-  point types. This allows access to ``llvm.round`` for
-  arbitrary floating-point and vector of floating-point types.
-- Added ``__builtin_elementwise_rint`` for floating point types. This
-  allows access to ``llvm.rint`` for arbitrary floating-point and
-  vector of floating-point types.
-- Added ``__builtin_elementwise_nearbyint`` for floating point
-  types. This allows access to ``llvm.nearbyint`` for arbitrary
-  floating-point and vector of floating-point types.
-- Clang AST matcher now matches concept declarations with `conceptDecl`.
 
 New Compiler Flags
 ------------------
-- The flag ``-std=c++23`` has been added. This behaves the same as the existing
-  flag ``-std=c++2b``.
-- ``-dumpdir`` has been implemented to specify auxiliary and dump output
-  filenames for features like ``-gsplit-dwarf``.
-- ``-fcaret-diagnostics-max-lines=`` has been added as a driver options, which
-  lets users control the maximum number of source lines printed for a
-  caret diagnostic.
-- ``-fkeep-persistent-storage-variables`` has been implemented to keep all
-  variables that have a persistent storage duration—including global, static
-  and thread-local variables—to guarantee that they can be directly addressed.
-  Since this inhibits the merging of the affected variables, the number of
-  individual relocations in the program will generally increase.
 
 Deprecated Compiler Flags
 -------------------------
 
-- ``-fdouble-square-bracket-attributes`` has been deprecated. It is ignored now
-  and will be removed in Clang 18.
-
 Modified Compiler Flags
 -----------------------
 
-- ``clang -g -gsplit-dwarf a.c -o obj/x`` (compile and link) now generates the
-  ``.dwo`` file at ``obj/x-a.dwo``, instead of a file in the temporary
-  directory (``/tmp`` on \*NIX systems, if none of the environment variables
-  TMPDIR, TMP, and TEMP are specified).
-
-- ``-ffat-lto-objects`` can now be used to emit object files with both object
-  code and LLVM bitcode. Previously this flag was ignored for GCC compatibility.
-  (`See related patch <https://reviews.llvm.org/D146777>`_).
-
 Removed Compiler Flags
 -------------------------
-- The deprecated flag `-fmodules-ts` is removed. Please use ``-std=c++20``
-  or higher to use standard C++ modules instead.
-- The deprecated flag `-fcoroutines-ts` is removed. Please use ``-std=c++20``
-  or higher to use standard C++ coroutines instead.
-- The CodeGen flag `-lower-global-dtors-via-cxa-atexit` which affects how global
-  destructors are lowered for MachO is removed without replacement. The default
-  of `-lower-global-dtors-via-cxa-atexit=true` is now the only supported way.
-- The cc1 flag ``-no-opaque-pointers`` has been removed.
 
 Attribute Changes in Clang
 --------------------------
-- Introduced a new function attribute ``__attribute__((unsafe_buffer_usage))``
-  to be worn by functions containing buffer operations that could cause out of
-  bounds memory accesses. It emits warnings at call sites to such functions when
-  the flag ``-Wunsafe-buffer-usage`` is enabled.
-- ``__declspec`` attributes can now be used together with the using keyword. Before
-  the attributes on ``__declspec`` was ignored, while now it will be forwarded to the
-  point where the alias is used.
-- Introduced a new ``USR`` (unified symbol resolution) clause inside of the
-  existing ``__attribute__((external_source_symbol))`` attribute. Clang's indexer
-  uses the optional USR value when indexing Clang's AST. This value is expected
-  to be generated by an external compiler when generating C++ bindings during
-  the compilation of the foreign language sources (e.g. Swift).
-- The ``__has_attribute``, ``__has_c_attribute`` and ``__has_cpp_attribute``
-  preprocessor operators now return 1 also for attributes defined by plugins.
-- Improve the AST fidelity of ``alignas`` and ``_Alignas`` attribute. Before, we
-  model ``alignas(type-id)`` as though the user wrote ``alignas(alignof(type-id))``,
-  now we directly use ``alignas(type-id)``.
 
 Improvements to Clang's diagnostics
 -----------------------------------
-- We now generate a diagnostic for signed integer overflow due to unary minus
-  in a non-constant expression context.
-  (`#31643 <https://github.com/llvm/llvm-project/issues/31643>`_)
-- Clang now warns by default for C++20 and later about deprecated capture of
-  ``this`` with a capture default of ``=``. This warning can be disabled with
-  ``-Wno-deprecated-this-capture``.
-- Clang had failed to emit some ``-Wundefined-internal`` for members of a local
-  class if that class was first introduced with a forward declaration.
-- Diagnostic notes and fix-its are now generated for ``ifunc``/``alias`` attributes
-  which point to functions whose names are mangled.
-- Diagnostics relating to macros on the command line of a preprocessed assembly
-  file or precompiled header are now reported as coming from the file
-  ``<command line>`` instead of ``<built-in>``.
-- Clang constexpr evaluator now provides a more concise diagnostic when calling
-  function pointer that is known to be null.
-- Clang now avoids duplicate warnings on unreachable ``[[fallthrough]];`` statements
-  previously issued from ``-Wunreachable-code`` and ``-Wunreachable-code-fallthrough``
-  by prioritizing ``-Wunreachable-code-fallthrough``.
-- Clang now correctly diagnoses statement attributes ``[[clang::always_inline]]`` and
-  ``[[clang::noinline]]`` when used on a statement with dependent call expressions.
-- Clang now checks for completeness of the second and third arguments in the
-  conditional operator.
-  (`#59718 <https://github.com/llvm/llvm-project/issues/59718>`_)
-- There were some cases in which the diagnostic for the unavailable attribute
-  might not be issued, this fixes those cases.
-  (`61815 <https://github.com/llvm/llvm-project/issues/61815>`_)
-- Clang now avoids unnecessary diagnostic warnings for obvious expressions in
-  the case of binary operators with logical OR operations.
-  (`#57906 <https://github.com/llvm/llvm-project/issues/57906>`_)
-- Clang's "static assertion failed" diagnostic now points to the static assertion
-  expression instead of pointing to the ``static_assert`` token.
-  (`#61951 <https://github.com/llvm/llvm-project/issues/61951>`_)
-- ``-Wformat`` now recognizes ``%lb`` for the ``printf``/``scanf`` family of
-  functions.
-  (`#62247: <https://github.com/llvm/llvm-project/issues/62247>`_).
-- Clang now diagnoses shadowing of lambda's template parameter by a capture.
-  (`#61105: <https://github.com/llvm/llvm-project/issues/61105>`_).
-- Address a false positive in ``-Wpacked`` when applied to a non-pod type using
-  Clang ABI >= 15.
-  (`#62353: <https://github.com/llvm/llvm-project/issues/62353>`_,
-  fallout from the non-POD packing ABI fix in LLVM 15).
-- Clang constexpr evaluator now prints subobject's name instead of its type in notes
-  when a constexpr variable has uninitialized subobjects after its constructor call.
-  (`#58601 <https://github.com/llvm/llvm-project/issues/58601>`_)
-- Clang's `-Wshadow` warning now warns about shadowings by static local variables
-  (`#62850: <https://github.com/llvm/llvm-project/issues/62850>`_).
-- Clang now warns when any predefined macro is undefined or redefined, instead
-  of only some of them.
-- Clang now correctly diagnoses when the argument to ``alignas`` or ``_Alignas``
-  is an incomplete type.
-  (`#55175: <https://github.com/llvm/llvm-project/issues/55175>`_, and fixes an
-  incorrect mention of ``alignof`` in a diagnostic about ``alignas``).
-- Clang will now show a margin with line numbers to the left of each line
-  of code it prints for diagnostics. This can be disabled using
-  ``-fno-diagnostics-show-line-numbers``. At the same time, the maximum
-  number of code lines it prints has been increased from 1 to 16. This
-  can be controlled using ``-fcaret-diagnostics-max-lines=``.
-- Clang no longer emits ``-Wunused-variable`` warnings for variables declared
-  with ``__attribute__((cleanup(...)))`` to match GCC's behavior.
-- Clang now issues expected warnings for situations of comparing with NULL pointers.
-  (`#42992: <https://github.com/llvm/llvm-project/issues/42992>`_)
-- Clang now diagnoses unused const-qualified variable template as
-  "unused variable template" rather than "unused variable".
-- When diagnosing a constant expression where an enum without a fixed underlying
-  type is set to a value outside the range of the enum's values, clang will now
-  print the name of the enum in question.
-- Clang no longer diagnoses a read of an empty structure as use of an
-  uninitialized variable.
-  (`#26842: <https://github.com/llvm/llvm-project/issues/26842>`_)
-- The Fix-It emitted for unused labels used to expand to the next line, which caused
-  visual oddities now that Clang shows more than one line of code snippet. This has
-  been fixed and the Fix-It now only spans to the end of the ``:``.
-- Clang now underlines the parameter list of function declaration when emitting
-  a note about the mismatch in the number of arguments.
-- Clang now diagnoses unexpected tokens after a
-  ``#pragma clang|GCC diagnostic push|pop`` directive.
-  (`#13920: <https://github.com/llvm/llvm-project/issues/13920>`_)
-- Clang now does not try to analyze cast validity on variables with dependent alignment (`#63007: <https://github.com/llvm/llvm-project/issues/63007>`_).
-- Clang constexpr evaluator now displays member function calls more precisely
-  by making use of the syntactical structure of function calls. This avoids display
-  of syntactically invalid codes in diagnostics.
-  (`#57081: <https://github.com/llvm/llvm-project/issues/57081>`_)
-- Clang no longer emits inappropriate notes about the loss of ``__unaligned`` qualifier
-  on overload resolution, when the actual reason for the failure is loss of other qualifiers.
-- The note emitted when an ``operator==`` was defaulted as deleted used to refer to
-  the lack of a data member's "three-way comparison operator". It now refers correctly
-  to the data member's ``operator==``.
-  (`#63960: <https://github.com/llvm/llvm-project/issues/63960>`_)
-- Clang's notes about unconvertible types in overload resolution failure now covers
-  the source range of parameter declaration of the candidate function declaration.
-
-  *Example Code*:
-
-  .. code-block:: c++
-
-     void func(int aa, int bb);
-     void test() { func(1, "two"); }
-
-  *BEFORE*:
-
-  .. code-block:: text
-
-    source:2:15: error: no matching function for call to 'func'
-    void test() { func(1, "two");  }
-                  ^~~~
-    source:1:6: note: candidate function not viable: no known conversion from 'const char[4]' to 'int' for 2nd argument
-    void func(int aa, int bb);
-         ^
-
-  *AFTER*:
-
-  .. code-block:: text
-
-    source:2:15: error: no matching function for call to 'func'
-    void test() { func(1, "two");  }
-                  ^~~~
-    source:1:6: note: candidate function not viable: no known conversion from 'const char[4]' to 'int' for 2nd argument
-    void func(int aa, int bb);
-         ^            ~~~~~~
-
-- ``-Wformat`` cast fix-its will now suggest ``static_cast`` instead of C-style casts
-  for C++ code.
-- ``-Wformat`` will no longer suggest a no-op fix-it for fixing scoped enum format
-  warnings. Instead, it will suggest casting the enum object to the type specified
-  in the format string.
-- Clang now emits ``-Wconstant-logical-operand`` warning even when constant logical
-  operand is on left side.
-  (`#37919 <https://github.com/llvm/llvm-project/issues/37919>`_)
 
 Bug Fixes in This Version
 -------------------------
 
-- Added a new diagnostic warning group
-  ``-Wdeprecated-redundant-constexpr-static-def``, under the existing
-  ``-Wdeprecated`` group. This controls warnings about out-of-line definitions
-  of 'static constexpr' data members that are unnecessary from C++17 onwards.
-- Fix segfault while running clang-rename on a non existing file.
-  (`#36471 <https://github.com/llvm/llvm-project/issues/36471>`_)
-- Fix crash when diagnosing incorrect usage of ``_Nullable`` involving alias
-  templates.
-  (`#60344 <https://github.com/llvm/llvm-project/issues/60344>`_)
-- Fix confusing warning message when ``/clang:-x`` is passed in ``clang-cl``
-  driver mode and emit an error which suggests using ``/TC`` or ``/TP``
-  ``clang-cl`` options instead.
-  (`#59307 <https://github.com/llvm/llvm-project/issues/59307>`_)
-- Fix assert that fails when the expression causing the this pointer to be
-  captured by a block is part of a constexpr if statement's branch and
-  instantiation of the enclosing method causes the branch to be discarded.
-- Fix __VA_OPT__ implementation so that it treats the concatenation of a
-  non-placemaker token and placemaker token as a non-placemaker token.
-  (`#60268 <https://github.com/llvm/llvm-project/issues/60268>`_)
-- Fix crash when taking the address of a consteval lambda call operator.
-  (`#57682 <https://github.com/llvm/llvm-project/issues/57682>`_)
-- Clang now support export declarations in the language linkage.
-  (`#60405 <https://github.com/llvm/llvm-project/issues/60405>`_)
-- Fix aggregate initialization inside lambda constexpr.
-  (`#60936 <https://github.com/llvm/llvm-project/issues/60936>`_)
-- No longer issue a false positive diagnostic about a catch handler that cannot
-  be reached despite being reachable. This fixes
-  `#61177 <https://github.com/llvm/llvm-project/issues/61177>`_ in anticipation
-  of `CWG2699 <https://wg21.link/CWG2699>_` being accepted by WG21.
-- Fix crash when parsing fold expression containing a delayed typo correction.
-  (`#61326 <https://github.com/llvm/llvm-project/issues/61326>`_)
-- Fix crash when dealing with some member accesses outside of class or member
-  function context.
-  (`#37792 <https://github.com/llvm/llvm-project/issues/37792>`_) and
-  (`#48405 <https://github.com/llvm/llvm-project/issues/48405>`_)
-- Fix crash when using ``[[clang::always_inline]]`` or ``[[clang::noinline]]``
-  statement attributes on a call to a template function in the body of a
-  template function.
-- Fix coroutines issue where ``get_return_object()`` result was always eagerly
-  converted to the return type. Eager initialization (allowing RVO) is now only
-  performed when these types match, otherwise deferred initialization is used,
-  enabling short-circuiting coroutines use cases. This fixes
-  (`#56532 <https://github.com/llvm/llvm-project/issues/56532>`_) in
-  anticipation of `CWG2563 <https://cplusplus.github.io/CWG/issues/2563.html>_`.
-- Fix highlighting issue with ``_Complex`` and initialization list with more than
-  2 items. (`#61518 <https://github.com/llvm/llvm-project/issues/61518>`_)
-- Fix  ``getSourceRange`` on  ``VarTemplateSpecializationDecl`` and
-  ``VarTemplatePartialSpecializationDecl``, which represents variable with
-  the initializer, so it behaves consistently with other ``VarDecls`` and ends
-  on the last token of initializer, instead of right angle bracket of
-  the template argument list.
-- Fix false-positive diagnostic issued for consteval initializers of temporary
-  objects.
-  (`#60286 <https://github.com/llvm/llvm-project/issues/60286>`_)
-- Correct restriction of trailing requirements clauses on a templated function.
-  Previously we only rejected non-'templated' things, but the restrictions ALSO need
-  to limit non-defined/non-member functions as well. Additionally, we now diagnose
-  requires on lambdas when not allowed, which we previously missed.
-  (`#61748 <https://github.com/llvm/llvm-project/issues/61748>`_)
-- Fix confusing diagnostic for incorrect use of qualified concepts names.
-- Fix handling of comments in function like macros so they are ignored in -CC
-  mode.
-  (`#60887 <https://github.com/llvm/llvm-project/issues/60887>`_)
-- Fix incorrect merging of lambdas across modules.
-  (`#60985 <https://github.com/llvm/llvm-project/issues/60985>`_)
-- Fix crash when handling nested immediate invocations in initializers of global
-  variables.
-  (`#58207 <https://github.com/llvm/llvm-project/issues/58207>`_)
-- Fix crash when generating code coverage information for `PseudoObjectExpr` in
-  Clang AST.
-  (`#45481 <https://github.com/llvm/llvm-project/issues/45481>`_)
-- Fix the assertion hit when a template consteval function appears in a nested
-  consteval/constexpr call chain.
-  (`#61142 <https://github.com/llvm/llvm-project/issues/61142>`_)
-- Clang now better diagnose placeholder types constrained with a concept that is
-  not a type concept.
-- Fix crash when a doc comment contains a line splicing.
-  (`#62054 <https://github.com/llvm/llvm-project/issues/62054>`_)
-- Work around with a clang coverage crash which happens when visiting
-  expressions/statements with invalid source locations in non-assert builds.
-  Assert builds may still see assertions triggered from this.
-- Fix a failed assertion due to an invalid source location when trying to form
-  a coverage report for an unresolved constructor expression.
-  (`#62105 <https://github.com/llvm/llvm-project/issues/62105>`_)
-- Fix defaulted equality operator so that it does not attempt to compare unnamed
-  bit-fields. This fixes:
-  (`#61355 <https://github.com/llvm/llvm-project/issues/61335>`_) and
-  (`#61417 <https://github.com/llvm/llvm-project/issues/61417>`_)
-- Fix crash after suggesting typo correction to constexpr if condition.
-  (`#61885 <https://github.com/llvm/llvm-project/issues/61885>`_)
-- Clang constexpr evaluator now treats comparison of [[gnu::weak]]-attributed
-  member pointer as an invalid expression.

 Bug Fixes to Compiler Builtins
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
 Bug Fixes to Attribute Support
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-- Fixed a bug where attribute annotations on type specifiers (enums, classes,
-  structs, unions, and scoped enums) were not properly ignored, resulting in
-  misleading warning messages. Now, such attribute annotations are correctly
-  ignored. (`#61660 <https://github.com/llvm/llvm-project/issues/61660>`_)
-- GNU attributes preceding C++ style attributes on templates were not properly
-  handled, resulting in compilation error. This has been corrected to match the
-  behavior exhibited by GCC, which permits mixed ordering of GNU and C++
-  attributes.

 Target Specific Changes
 -----------------------
 
 AMDGPU Support
 ^^^^^^^^^^^^^^
 
-- Linking for AMDGPU now uses ``--no-undefined`` by default. This causes
-  undefined symbols in the created module to be a linker error. To prevent this,
-  pass ``-Wl,--undefined`` if compiling directly, or ``-Xoffload-linker
-  --undefined`` if using an offloading language.
-- The deprecated ``-mcode-object-v3`` and ``-mno-code-object-v3`` command-line
-  options have been removed.
-- A new option ``-mprintf-kind`` has been introduced that controls printf lowering
-  scheme. It is currently supported only for HIP and takes following values,
-  ``hostcall`` - printing happens during kernel execution via series of hostcalls,
-  The scheme requires the system to support pcie atomics.(default)
-  ``buffered`` - Scheme uses a debug buffer to populate printf varargs, does not
-  rely on pcie atomics support.
-
 X86 Support
 ^^^^^^^^^^^
 
-- Add ISA of ``AMX-COMPLEX`` which supports ``tcmmimfp16ps`` and
-  ``tcmmrlfp16ps``.
-- Support ISA of ``SHA512``.
-  * Support intrinsic of ``_mm256_sha512msg1_epi64``.
-  * Support intrinsic of ``_mm256_sha512msg2_epi64``.
-  * Support intrinsic of ``_mm256_sha512rnds2_epi64``.
-- Support ISA of ``SM3``.
-  * Support intrinsic of ``_mm_sm3msg1_epi32``.
-  * Support intrinsic of ``_mm_sm3msg2_epi32``.
-  * Support intrinsic of ``_mm_sm3rnds2_epi32``.
-- Support ISA of ``SM4``.
-  * Support intrinsic of ``_mm(256)_sm4key4_epi32``.
-  * Support intrinsic of ``_mm(256)_sm4rnds4_epi32``.
-- Support ISA of ``AVX-VNNI-INT16``.
-  * Support intrinsic of ``_mm(256)_dpwsud(s)_epi32``.
-  * Support intrinsic of ``_mm(256)_dpwusd(s)_epi32``.
-  * Support intrinsic of ``_mm(256)_dpwuud(s)_epi32``.
-- ``-march=graniterapids-d`` is now supported.
-
 Arm and AArch64 Support
 ^^^^^^^^^^^^^^^^^^^^^^^
 
-- The hard-float ABI is now available in Armv8.1-M configurations that
-  have integer MVE instructions (and therefore have FP registers) but
-  no scalar or vector floating point computation. Previously, trying
-  to select the hard-float ABI on such a target (via
-  ``-mfloat-abi=hard`` or a triple ending in ``hf``) would silently
-  use the soft-float ABI instead.
-
-- Clang builtin ``__arithmetic_fence`` and the command line option ``-fprotect-parens``
-  are now enabled for AArch64.
-
-- Clang supports flag output operands by which conditions in the NZCV could be outputs
-  of inline assembly for AArch64. This change is more consistent with the behavior of
-  GCC.
-
-   .. code-block:: c
-
-     // int a = foo(); int* b = bar();
-     asm("ands %w[a], %w[a], #3" : [a] "+r"(a), "=@cceq"(*b));
-
-- Fix a crash when ``preserve_all`` calling convention is used on AArch64.
-  `Issue 58145 <https://github.com/llvm/llvm-project/issues/58145>`_
-
 Windows Support
 ^^^^^^^^^^^^^^^
 
 LoongArch Support
 ^^^^^^^^^^^^^^^^^
 
-- Patchable function entry (``-fpatchable-function-entry``) is now supported
-  on LoongArch.
-- Unaligned memory accesses can be toggled by ``-m[no-]unaligned-access`` or the
-  aliases ``-m[no-]strict-align``.
-- Non ``$``-prefixed GPR names (e.g. ``r4`` and ``a0``) are allowed in inlineasm
-  like GCC does.
-
 RISC-V Support
 ^^^^^^^^^^^^^^
-- Added ``-mrvv-vector-bits=`` option to give an upper and lower bound on vector
-  length. Valid values are powers of 2 between 64 and 65536. A value of 32
-  should eventually be supported. We also accept "zvl" to use the Zvl*b
-  extension from ``-march`` or ``-mcpu`` to the be the upper and lower bound.
-- Fixed incorrect ABI lowering of ``_Float16`` in the case of structs
-  containing ``_Float16`` that are eligible for passing via GPR+FPR or
-  FPR+FPR.
-- Removed support for ``__attribute__((interrupt("user")))``. User-level
-  interrupts are not in version 1.12 of the privileged specification.
-- Added ``attribute(riscv_rvv_vector_bits(__riscv_v_fixed_vlen))`` to allow
-  the size of a RVV (RISC-V Vector) scalable type to be specified. This allows
-  RVV scalable vector types to be used in structs or in global variables.
-- The rules for ordering of extensions in ``-march`` strings were relaxed. A
-  canonical ordering is no longer enforced on ``z*``, ``s*``, and ``x*``
-  prefixed extensions.
 
 CUDA/HIP Language Changes
 ^^^^^^^^^^^^^^^^^^^^^^^^^
-- Clang has been updated to align its default language standard for CUDA/HIP with
-  that of C++. The standard has now been enhanced to gnu++17, supplanting the
-  previously used c++14.
 
 CUDA Support
 ^^^^^^^^^^^^
-- Clang now supports CUDA SDK up to 12.1
 
 AIX Support
 ^^^^^^^^^^^
-- Add an AIX-only link-time option, `-mxcoff-build-id=0xHEXSTRING`, to allow users
-  to embed a hex id in their binary such that it's readable by the program itself.
-  This option is an alternative to the `--build-id=0xHEXSTRING` GNU linker option
-  which is currently not supported by the AIX linker.
-
-- Introduced the ``-mxcoff-roptr`` option to place constant objects with
-  relocatable address values in the read-only data section. This option should
-  be used with the ``-fdata-sections`` option, and is not supported with
-  ``-fno-data-sections``. When ``-mxcoff-roptr`` is in effect at link time,
-  read-only data sections with relocatable address values that resolve to
-  imported symbols are made writable.
 
 WebAssembly Support
 ^^^^^^^^^^^^^^^^^^^
-- Shared library support (and PIC code generation) for WebAssembly is no longer
-  limited to the Emscripten target OS and now works with other targets such as
-  wasm32-wasi.  Note that the `format
-  <https://github.com/WebAssembly/tool-conventions/blob/main/DynamicLinking.md>`_
-  is not yet stable and may change between LLVM versions.  Also, WASI does not
-  yet have facilities to load dynamic libraries.
 
 AVR Support
 ^^^^^^^^^^^
-- The definition of ``USHRT_MAX`` in the freestanding ``<limits.h>`` no longer
-  overflows on AVR (where ``sizeof(int) == sizeof(unsigned short)``).  The type
-  of ``USHRT_MAX`` is now ``unsigned int`` instead of ``int``, as required by
-  the C standard.
 
 DWARF Support in Clang
 ----------------------
 
 Floating Point Support in Clang
 -------------------------------
-- Add ``__builtin_elementwise_log`` builtin for floating point types only.
-- Add ``__builtin_elementwise_log10`` builtin for floating point types only.
-- Add ``__builtin_elementwise_log2`` builtin for floating point types only.
-- Add ``__builtin_elementwise_exp`` builtin for floating point types only.
-- Add ``__builtin_elementwise_exp2`` builtin for floating point types only.
-- Add ``__builtin_set_flt_rounds`` builtin for X86, x86_64, Arm and AArch64 only.
-- Add ``__builtin_elementwise_pow`` builtin for floating point types only.
 
 AST Matchers
 ------------
 
-- Add ``coroutineBodyStmt`` matcher.
-
-- The ``hasBody`` matcher now matches coroutine body nodes in
-  ``CoroutineBodyStmts``.
-
-- Add ``arrayInitIndexExpr`` and ``arrayInitLoopExpr`` matchers.
-
 clang-format
 ------------
 
-- Add ``NextLineOnly`` style to option ``PackConstructorInitializers``.
-  Compared to ``NextLine`` style, ``NextLineOnly`` style will not try to
-  put the initializers on the current line first, instead, it will try to
-  put the initializers on the next line only.
-- Add additional Qualifier Ordering support for special cases such
-  as templates, requires clauses, long qualified names.
-- Fix all known issues associated with ``LambdaBodyIndentation: OuterScope``.
-- Add ``BracedInitializerIndentWidth`` which can be used to configure
-  the indentation level of the contents of braced init lists.
-- Add ``KeepEmptyLinesAtEOF`` to keep empty lines at end of file.
-- Add ``RemoveParentheses`` to remove redundant parentheses.
-- Add ``TypeNames`` to treat listed non-keyword identifiers as type names.
-- Add ``AlignConsecutiveShortCaseStatements`` which can be used to align case
-  labels in conjunction with ``AllowShortCaseLabelsOnASingleLine``.
-- Add ``SpacesInParens`` style with ``SpacesInParensOptions`` to replace
-  ``SpacesInConditionalStatement``, ``SpacesInCStyleCastParentheses``,
-  ``SpaceInEmptyParentheses``, and ``SpacesInParentheses``.
-
 libclang
 --------
 
-- Introduced the new function ``clang_CXXMethod_isExplicit``,
-  which identifies whether a constructor or conversion function cursor
-  was marked with the explicit identifier.
-
-- Introduced the new ``CXIndex`` constructor function
-  ``clang_createIndexWithOptions``, which allows storing precompiled preambles
-  in memory or overriding the precompiled preamble storage path.
-
-- Deprecated two functions ``clang_CXIndex_setGlobalOptions`` and
-  ``clang_CXIndex_setInvocationEmissionPathOption`` in favor of the new
-  function ``clang_createIndexWithOptions`` in order to improve thread safety.
-
-- Added check in ``clang_getFieldDeclBitWidth`` for whether a bit-field
-  has an evaluable bit width. Fixes undefined behavior when called on a
-  bit-field whose width depends on a template parameter.
-
-- Added ``CXBinaryOperatorKind`` and ``CXUnaryOperatorKind``.

-  (`#60465 <https://github.com/llvm/llvm-project/issues/60465>`_)
-
-- Removed the deprecated

-
-- Better modeling of lifetime-extended memory regions. As a result, the
-  ``MoveChecker`` raises more true-positive reports.
-
-- Fixed some bugs (including crashes) around the handling of constant global
-  arrays and their initializer expressions.
-
-- The ``CStringChecker`` will invalidate less if the copy operation is
-  inferable to be bounded. For example, if the arguments of ``strcpy`` are
-  known to be of certain lengths and that are in-bounds.

-    // extent of 'arr' is 4, and writing "hi\n" (4 characters),
-    // thus no buffer overflow can happen
-    strcpy(x.arr, "hi\n");
-    free(x.ptr); // no longer reports memory leak here
-
-  Similarly, functions like ``strsep`` now won't invalidate the object
-  containing the destination buffer, because it can never overflow.
-  Note that, ``std::copy`` is still not modeled, and as such, it will still
-  invalidate the enclosing object on call.
-  (`#55019 <https://github.com/llvm/llvm-project/issues/55019>`_)
-
-- Implement ``BufferOverlap`` check for ``sprint``/``snprintf``
-  The ``CStringChecker`` checks for buffer overlaps for ``sprintf`` and
-  ``snprintf``.
-
-- Objective-C support was improved around checking ``_Nonnull`` and
-  ``_Nullable`` including block pointers and literal objects.
-
-- Let the ``StreamChecker`` detect ``NULL`` streams instead of by
-  ``StdCLibraryFunctions``.
-  ``StreamChecker`` improved on the ``fseek`` modeling for the ``SEEK_SET``,
-  ``SEEK_END``, ``SEEK_CUR`` arguments.
-
-- ``StdCLibraryFunctionArgs`` was merged into the ``StdCLibraryFunctions``.
-  The diagnostics of the ``StdCLibraryFunctions`` was improved.
-
-- ``QTimer::singleShot`` now doesn't raise false-positives for memory leaks by
-  the ``MallocChecker``.
-  (`#39713 <https://github.com/llvm/llvm-project/issues/39713>`_)
-
-- Fixed the infamous unsigned index false-positives in the
-  ``ArrayBoundCheckerV2`` checker.
-  (`#44493 <https://github.com/llvm/llvm-project/issues/44493>`_)
-
-- Now, taint propagations are tracked further back until the real taint source.
-  This improves all taint-related diagnostics.
-
-- Fixed a null-pointer dereference crash inside the ``MoveChecker``.

 ## Major New Features
 
-* Flang now supports loading LLVM pass plugins with the `-fpass-plugin` option
-  which is also available in clang. The option mimics the behavior of the
-  corresponding option in clang and has the same capabilities and limitations.
-* Flang also supports statically linked LLVM pass extensions. Projects can be
-  linked statically into `flang-new` if the cmake command includes
-  `-DLLVM_${NAME}_LINK_INTO_TOOLS=ON`. This behavior is also similar to clang.
-
 ## Bug Fixes
 
 ## Non-comprehensive list of changes in this release
-* The bash wrapper script, `flang`, is renamed as `flang-to-external-fc`.
-* In contrast to Clang, Flang will not default to using `-fpie` when linking
-  executables. This is only a temporary solution and the goal is to align with
-  Clang in the near future. First, however, the frontend driver needs to be
-  extended so that it can generate position independent code (that requires
-  adding support for e.g. `-fpic` and `-mrelocation-model` in `flang-new
-  -fc1`). Once that is available, support for the `-fpie` can officially be
-  added and the default behaviour updated.
 
 ## New Compiler Flags
-* Refined how `-f{no-}color-diagnostics` is treated to better align with Clang.
-  In particular, both `-fcolor-diagnostics` and `-fno-color-diagnostics` are
-  now available in `flang-new` (the diagnostics are formatted by default). In
-  the frontend driver, `flang-new -fc1`, only `-fcolor-diagnostics` is
-  available (by default, the diagnostics are not formatted).

 Update on required toolchains to build LLVM
 -------------------------------------------
 
-With LLVM 17.x we raised the version requirement of CMake used to build LLVM.
-The new requirements are as follows:
-
-* CMake >= 3.20.0
-
 Changes to the LLVM IR
 ----------------------
 
-* Typed pointers are no longer supported and the ``-opaque-pointers`` option
-  has been removed. See the `opaque pointers <OpaquePointers.html>`__
-  documentation for migration instructions.
-
-* The ``nofpclass`` attribute was introduced. This allows more
-  optimizations around special floating point value comparisons.
-
-* Introduced new ``llvm.ldexp`` and ``llvm.experimental.constrained.ldexp`` intrinsics.
-
-* Introduced new ``llvm.frexp`` intrinsic.
-
-* The constant expression variants of the following instructions have been
-  removed:
-
-  * ``select``
-
-* Introduced a set of experimental `convergence control intrinsics
-  <ConvergentOperations.html>`__ to explicitly define the semantics of convergent
-  operations.
-
 Changes to LLVM infrastructure
 ------------------------------
 
-* The legacy optimization pipeline has been removed.
-
-* Alloca merging in the inliner has been removed, since it only worked with the
-  legacy inliner pass. Backend stack coloring should handle cases alloca
-  merging initially set out to handle.
-
-* InstructionSimplify APIs now require instructions be inserted into a
-  parent function.
-
-* A new FatLTO pipeline was added to support generating object files that have
-  both machine code and LTO compatible bitcode. See the :doc:`FatLTO`
-  documentation and the original
-  `RFC  <https://discourse.llvm.org/t/rfc-ffat-lto-objects-support/63977>`_
-  for more details.
-
 Changes to building LLVM
 ------------------------
 
 Changes to TableGen
 -------------------
 
-* Named arguments are supported. Arguments can be specified in the form of
-  ``name=value``.
-
 Changes to Interprocedural Optimizations
 ----------------------------------------
 
 Changes to the AArch64 Backend
 ------------------------------
 
-* Added Assembly Support for the 2022 A-profile extensions FEAT_GCS (Guarded
-  Control Stacks), FEAT_CHK (Check Feature Status), and FEAT_ATS1A.
-* Support for preserve_all calling convention is added.
-* Added support for missing arch extensions in the assembly directives
-  ``.arch <level>+<ext>`` and ``.arch_extension``.
-* Fixed handling of ``.arch <level>`` in assembly, without using any ``+<ext>``
-  suffix. Previously this had no effect at all if no extensions were supplied.
-  Now ``.arch <level>`` can be used to enable all the extensions that are
-  included in a higher level than what is specified on the command line,
-  or for disabling unwanted extensions if setting it to a lower level.
-  This fixes `PR32873 <https://github.com/llvm/llvm-project/issues/32220>`.
-
 Changes to the AMDGPU Backend
 -----------------------------
-* More fine-grained synchronization around barriers for newer architectures
-  (gfx90a+, gfx10+). The AMDGPU backend now omits previously automatically
-  generated waitcnt instructions before barriers, allowing for more precise
-  control. Users must now use memory fences to implement fine-grained
-  synchronization strategies around barriers. Refer to `AMDGPU memory model
-  <AMDGPUUsage.html#memory-model>`__.
-
-* Address space 7, used for *buffer fat pointers* has been added.
-  It is non-integral and has 160-bit pointers (a 128-bit raw buffer resource and a
-  32-bit offset) and 32-bit indices. This is part of ongoing work to improve
-  the usability of buffer operations. Refer to `AMDGPU address spaces
-  <AMDGPUUsage.html#address-spaces>`__.
-
-* Address space 8, used for *buffer resources* has been added.
-  It is non-integral and has 128-bit pointers, which correspond to buffer
-  resources in the underlying hardware. These pointers should not be used with
-  `getelementptr` or other LLVM memory instructions, and can be created with
-  the `llvm.amdgcn.make.buffer.rsrc` intrinsic. Refer to `AMDGPU address spaces
-  <AMDGPUUsage.html#address_spaces>`__.
-
-* New versions of the intrinsics for working with buffer resources have been added.
-  These `llvm.amdgcn.*.ptr.[t]buffer.*` intrinsics have the same semantics as
-  the old `llvm.amdgcn.*.[t]buffer.*` intrinsics, except that their `rsrc`
-  arguments are represented by a `ptr addrspace(8)` instead of a `<4 x i32>`. This
-  improves the interaction between AMDGPU buffer operations and the LLVM memory
-  model, and so the non `.ptr` intrinsics are deprecated.
-
-* Removed ``llvm.amdgcn.atomic.inc`` and ``llvm.amdgcn.atomic.dec``
-  intrinsics. :ref:`atomicrmw <i_atomicrmw>` should be used instead
-  with ``uinc_wrap`` and ``udec_wrap``.
-
-* Added llvm.amdgcn.log.f32 intrinsic. This provides direct access to
-  v_log_f32.
-
-* Added llvm.amdgcn.exp2.f32 intrinsic. This provides direct access to
-  v_exp_f32.
-
-* llvm.log2.f32, llvm.log10.f32, and llvm.log.f32 are now lowered
-  accurately. Use llvm.amdgcn.log.f32 to access the old behavior for
-  llvm.log2.f32.
-
-* llvm.exp2.f32 and llvm.exp.f32 are now lowered accurately. Use
-  llvm.amdgcn.exp2.f32 to access the old behavior for llvm.exp2.f32.
-
-* Implemented new 1ulp IEEE lowering strategy for float reciprocal
-  which saves 2 instructions. This is used by default for OpenCL on
-  gfx9+. With ``contract`` flags, this will fold into a 1 ulp rsqrt.
-
-* Implemented new 2ulp IEEE lowering strategy for float

-  defaulted template parameters. (`D142268 <https://reviews.llvm.org/D142268>`_)
-
-* The experimental ``@llvm.dbg.addr`` intrinsic has been removed (`D144801
-  <https://reviews.llvm.org/D144801>`_). IR inputs with this intrinsic are
-  auto-upgraded to ``@llvm.dbg.value`` with ``DW_OP_deref`` appended to the
-  ``DIExpression`` (`D144793 <https://reviews.llvm.org/D144793>`_).
-
-* When a template class annotated with the ``[[clang::preferred_name]]`` attribute
-  were to appear in a ``DW_AT_type``, the type will now be that of the preferred_name
-  instead. This change is only enabled when compiling with `-glldb`.

 Changes to the LLVM tools
 ---------------------------------
-* llvm-lib now supports the /def option for generating a Windows import library from a definition file.
-
-* Made significant changes to JSON output format of `llvm-readobj`/`llvm-readelf`
-  to improve correctness and clarity.
 
 Changes to LLDB
 ---------------------------------
 
-* In the results of commands such as ``expr`` and ``frame var``, type summaries will now
-  omit defaulted template parameters. The full template parameter list can still be
-  viewed with ``expr --raw-output``/``frame var --raw-output``. (`D141828 <https://reviews.llvm.org/D141828>`_)
-
-* LLDB is now able to show the subtype of signals found in a core file. For example
-  memory tagging specific segfaults such as ``SIGSEGV: sync tag check fault``.
-
-* LLDB can now display register fields if they are described in target XML sent
-  by a debug server such as ``gdbserver`` (``lldb-server`` does not currently produce
-  this information). Fields are only printed when reading named registers, for
-  example ``register read cpsr``. They are not shown when reading a register set,
-  ``register read -s 0``.
-
-* A new command ``register info`` was added. This command will tell you everything that
-  LLDB knows about a register. Based on what LLDB already knows and what the debug
-  server tells it. Including but not limited to, the size, where it is read from and
-  the fields that the register contains.
-
 Changes to Sanitizers
 ---------------------
-* For Darwin users that override weak symbols, note that the dynamic linker will
-  only consider symbols in other mach-o modules which themselves contain at
-  least one weak symbol. A consequence is that if your program or dylib contains
-  an intended override of a weak symbol, then it must contain at least one weak
-  symbol as well for the override to take effect.
-
-  Example:
-
-  .. code-block:: c
-
-    // Add this to make sure your override takes effect
-    __attribute__((weak,unused)) unsigned __enableOverrides;
-
-    // Example override
-    extern "C" const char *__asan_default_options() { ... }
 
 Other Changes
 -------------
 
-* ``llvm::demangle`` now takes a ``std::string_view`` rather than a
-  ``const std::string&``. Be careful passing temporaries into
-  ``llvm::demangle`` that don't outlive the expression using
-  ``llvm::demangle``.

 Non-comprehensive list of changes in this release
 =================================================
-
-- Removed the "old" device plugins along with support for the ``remote`` and
-  ``ve`` plugins
-- Added basic experimental support for ``libc`` functions on the GPU via the
-  `LLVM C Library for GPUs <https://libc.llvm.org/gpu/>`_.
-- Added minimal support for calling host functions from the device using the
-  ``libc`` interface, see this `example
-  <https://github.com/llvm/llvm-project/blob/main/openmp/libomptarget/test/libc/host_call.c>`_.
-- Fixed the implementation of ``omp_get_wtime`` for AMDGPU targets.
-- Added vendor agnostic OMPT callback support for OpenMP-based device offload.

-
-- Support for -polly-vectorizer=polly has been removed. Polly's internal
-  vectorizer is not well maintained and is known to not work in some cases
-  such as region ScopStmts. Unlike LLVM's LoopVectorize pass it also does
-  not have a target-dependent cost heuristics, and we recommend using
-  LoopVectorize instead of -polly-vectorizer=polly.
-
-  In the future we hope that Polly can collaborate better with LoopVectorize,
-  like Polly marking a loop is safe to vectorize with a specific simd width,
-  instead of replicating its functionality.
-
-- Polly-ACC has been removed.
