clang/docs/ReleaseNotes.rst

- Improved the diagnostic when accessing a member of an atomic structure or
   union object in C; was previously an unhelpful error, but now issues a
   `-Watomic-access` warning which defaults to an error. Fixes
   `Issue 54563 <https://github.com/llvm/llvm-project/issues/54563>`_.
 - Unevaluated lambdas in dependant contexts no longer result in clang crashing.
   This fixes Issues `50376 <https://github.com/llvm/llvm-project/issues/50376>`_,
   `51414 <https://github.com/llvm/llvm-project/issues/51414>`_,
   `51416 <https://github.com/llvm/llvm-project/issues/51416>`_,
   and `51641 <https://github.com/llvm/llvm-project/issues/51641>`_.

+- The builtin function __builtin_dump_struct would crash clang when the target 
+  struct contains a bitfield. It now correctly handles bitfields.
+  This fixes Issue `Issue 54462 <https://github.com/llvm/llvm-project/issues/54462>`_.
 
 Improvements to Clang's diagnostics
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 - ``-Wliteral-range`` will warn on floating-point equality comparisons with
   constants that are not representable in a casted value. For example,
   ``(float) f == 0.1`` is always false.
 - ``-Winline-namespace-reopened-noninline`` now takes into account that the
   ``inline`` keyword must appear on the original but not necessarily all
   extension definitions of an inline namespace and therefore points its note
   at the original definition. This fixes `Issue 50794 (PR51452)
   <https://github.com/llvm/llvm-project/issues/50794>`_.
 - ``-Wunused-but-set-variable`` now also warns if the variable is only used
   by unary operators.
 
 Non-comprehensive list of changes in this release
 -------------------------------------------------
-- The builtin function __builtin_dump_struct would crash clang when the target 
-  struct have bitfield. Now it fixed, and __builtin_dump_struct support dump
-  the bitwidth of bitfields.
-  This fixes `Issue 54462 <https://github.com/llvm/llvm-project/issues/54462>`_.
+- Improve __builtin_dump_struct:
+  - Support bitfields in struct and union.
+  - Improve the dump format, dump both bitwidth(if its a bitfield) and field value.
 
 New Compiler Flags
 ------------------
 
 Deprecated Compiler Flags
 -------------------------
 
 Modified Compiler Flags

 - Statement attributes ``[[clang::noinline]]`` and  ``[[clang::always_inline]]``
   can be used to control inlining decisions at callsites.
 
 - ``#pragma clang attribute push`` now supports multiple attributes within a single directive.
 
 - The ``__declspec(naked)`` attribute can no longer be written on a member
   function in Microsoft compatibility mode, matching the behavior of cl.exe.
 
-- Improve __builtin_dump_struct:
-
-  - Support bitfields in struct and union.
-  
-  - Improve the dump format, dump both bitwidth(if its a bitfield) and field value.
-
 Windows Support
 ---------------
 
 - Add support for MSVC-compatible ``/JMC``/``/JMC-`` flag in clang-cl (supports
   X86/X64/ARM/ARM64). ``/JMC`` could only be used when ``/Zi`` or ``/Z7`` is
   turned on. With this addition, clang-cl can be used in Visual Studio for the
   JustMyCode feature. Note, you may need to manually add ``/JMC`` as additional
   compile options in the Visual Studio since it currently assumes clang-cl does not support ``/JMC``.
