Improvements to clangd
----------------------
-The improvements are...
+Code Completion
+^^^^^^^^^^^^^^^
+
+- ML based model is used by default for ranking completion candidates.
+
+- Support for completion of attributes.
+
+- Improved handling of Objective-C(++) constructs.
+
+
+Hover
+^^^^^
+
+- Shows documentation for Attributes.
+
+- Displays resolved paths for includes.
+
+- Shows padding for fields.
+
+Document Outline
+^^^^^^^^^^^^^^^^
+
+- Contains information in detail field about extra type information
+
+- Macro expansions now show up in the tree
+
+- Improved handling of Objective-C(++) constructs.
+
+Code Navigation
+^^^^^^^^^^^^^^^^
+
+- Cross references surfaces occurrences for calls to overridden methods and
+ declarations.
+
+Semantic Highlighting
+^^^^^^^^^^^^^^^^^^^^^
+
+- Support for legacy semantic tokens extension is dropped.
+
+- Better support for Objective-C(++) constructs and dependent code.
+
+
+Diagnostics
+^^^^^^^^^^^
+
+- Diagnostics for unused/deprecated code are tagged according to LSP.
+
+- Clang-tidy checks that operate at translation-unit level are now available.
+
+System Integration
+^^^^^^^^^^^^^^^^^^
+
+- Compile flag parsing has been improved to be more resilient against multiple
+ jobs.
+
+- Better error reporting when compile flags are unusable.
+
+
+Miscellaneous
+^^^^^^^^^^^^^
+
+- Better support for TUs with circular includes (e.g. templated header vs
+ implementation file).
+
+- Compile flags for headers are inferred from files known to be including them
+ when possible.
+
+- Version info contains information about compile-time setup of clangd
+
+- FeatureModule mechanism has been introduced to make contribution of vertical
+ features to clangd easier, by making it possible to write features that can
+ interact with clangd-core without touching it.
+
+- There's an extension for inlay-hints for deduced types and parameter names,
+ hidden behind -inlay-hints flag.
+
+- Rename is more robust:
+
+ - Won't trigger on non-identifiers.
+ - Makes use of dirty buffers for open files.
+
+- Improvements to dex query latency.
+
+- There's a remote-index service for LLVM at http://clangd-index.llvm.org/.
+
+- There's a remote-index service for Chromium at
+ https://linux.clangd-index.chromium.org/.

+- The C++20 type ``std::counted_semaphore<N>`` is now based on ``std::atomic``
+ on all platforms, and does not use "native" semaphores such as pthreads
+ ``sem_t`` even on platforms that would support them. This changes the layout

+-z start-stop-gc
+================
+
+If your ``-Wl,--gc-sections`` build fail with a linker error like this:
+
+ error: undefined symbol: __start_meta
+ >>> referenced by {{.*}}
+ >>> the encapsulation symbol needs to be retained under --gc-sections
properly; consider -z nostart-stop-gc (see
https://lld.llvm.org/ELF/start-stop-gc)
+
+it is likely your C identifier name sections are not properly annotated to
+suffice under ``--gc-sections``.
+
+``__start_meta`` and ``__stop_meta`` are sometimed called encapsulation
+symbols. In October 2015, GNU ld switched behavior and made a ``__start_meta``
+reference from a live section retain all ``meta`` input sections. This
+conservative behavior works for existing code which does not take GC into fair
+consideration, but unnecessarily increases sizes for modern metadata section
+usage which desires precise GC.
+
+GNU ld 2.37 added ``-z start-stop-gc`` to restore the traditional behavior
+ld.lld 13.0.0 defaults to ``-z start-stop-gc`` and supports ``-z
nostart-stop-gc``
+to switch to the conservative behavior.
+
+The Apple ld64 linker has a similar ``section$start`` feature and always
+allowed GC (like ``-z start-stop-gc``).
+
+Annotate C identifier name sections
+-----------------------------------
+
+A C identifier name section (``meta``) sometimes depends on another section.
+Let that section reference ``meta`` via a relocation.
+
+.. code-block:: c
+
+ asm(".pushsection .init_array,\"aw\",%init_array\n" \
+ ".reloc ., BFD_RELOC_NONE, meta\n" \
+ ".popsection\n")
+
+If a relocation is inconvenient, consider using ``__attribute__((retain))``
+(GCC 11 with modern binutils, Clang 13).
+
+.. code-block:: c
+
+ #pragma GCC diagnostic push
+ #pragma GCC diagnostic ignored "-Wattributes"
+ __attribute__((retain,used,section("meta")))
+ static const char dummy[0];
+ #pragma GCC diagnostic pop
+
+GCC before 11 and Clang before 13 do not recognize ``__attribute__((retain))``,
+so ``-Wattributes`` may need to be ignored. On ELF targets,
+``__attribute__((used))`` prevents compiler discarding, but does not affect
+linker ``--gc-sections``.
+
+In a macro, you may use:
+
+.. code-block:: c
+
+ _Pragma("GCC diagnostic push")
+ _Pragma("GCC diagnostic ignored \"-Wattributes\"")
+ ...
+ _Pragma("GCC diagnostic pop")
+
+If you use the ``SECTIONS`` command in a linker script, use
+`the ``KEEP`` keyword
<https://sourceware.org/binutils/docs/ld/Input-Section-Keep.html>`_, e.g.
+``meta : { KEEP(*(meta)) }``
