Non-comprehensive list of changes in this release

ELF Improvements

|
----------------

|
|
(`D129406 <https://reviews.llvm.org/D129406>`_)

|

Breaking changes

----------------

|
|
|
COFF Improvements
|
|
-----------------
|
|
|
|
* ...
|
|
|
|
MinGW Improvements
|
|
------------------
|
|
|
|
* The lld-specific options ``--guard-cf``, ``--no-guard-cf``,
|
|
``--guard-longjmp`` and ``--no-guard-longjmp`` has been added to allow
|
|
enabling Control Flow Guard and long jump hardening. These options are
|
|
disabled by default, but enabling ``--guard-cf`` will also enable
|
|
``--guard-longjmp`` unless ``--no-guard-longjmp`` is also specified.
|
|
``--guard-longjmp`` depends on ``--guard-cf`` and cannot be used by itself.
|
|
Note that these features require the ``_load_config_used`` symbol to contain
|
|
the load config directory and be filled with the required symbols.
