Changes to the C API
--------------------
* The C API functions ``LLVMGetAlignment`` and ``LLVMSetAlignment`` now allow
changing alignment on atomicrmw and cmpxchg instructions
* A new entry ``LLVMDIArgListMetadataKind`` was added to the
``LLVMMetadataKind`` enum, representing DIArgLists
(`D88175 <https://reviews.llvm.org/D88175>`_)
* Type attributes have been added to LLVM-C, introducing
LLVMCreateTypeAttribute, LLVMGetTypeAttributeValue and LLVMIsTypeAttribute.
(`D977763' <https://reviews.llvm.org/D97763>`_)
* The ``LTO_API_VERSION`` was bumped to 28, introducing a new function
``lto_set_debug_options`` for parsing LTO debug options
(`D92611 <https://reviews.llvm.org/D92611>`_)
* ``LLVMJITTargetSymbolFlags`` was renamed to ``LLVMJITSymbolTargetFlags``
(`rG8d718a0bff73af066675a6258c01307937c33cf9
<https://reviews.llvm.org/rG8d718a0bff73af066675a6258c01307937c33cf9>`_)
* The C API received support for creating custom ORCv2 MaterializationUnits and
APIs to retrieve an LLJIT instance's linking layers. An ABI breaking change
for ``LLVMOrcAbsoluteSymbols`` was introduced to make it consistent with
``LLVMOrcCreateCustomMaterializationUnit``.
(`rGc8fc5e3ba942057d6c4cdcd1faeae69a28e7b671
<https://reviews.llvm.org/rGc8fc5e3ba942057d6c4cdcd1faeae69a28e7b671>`_)
* The C API received support for adding ORCv2 object buffers directly to an object
layer. (`rG7b73cd684a8d5fb44d34064200f10e2723085c33
<https://reviews.llvm.org/rG7b73cd684a8d5fb44d34064200f10e2723085c33>`_)
* A breaking change to ``LLVMGetInlineAsm`` was introduced, adding a ninth
argument ``LLVMBool CanThrow`` (`D95745 <https://reviews.llvm.org/D95745>`_)
* The C API received support for calling into the new pass manager.
(`D102136 <https://reviews.llvm.org/D102136>`_)
* The C API function ``LLVMIntrinsicCopyOverloadedName`` has been deprecated.
Please migrate to ``LLVMIntrinsicCopyOverloadedName2`` which takes an extra
module argument and which also handles unnamed types.
('D99173' <https://reviews.llvm.org/D99173>'_)
(`D99173 <https://reviews.llvm.org/D99173>`_)
* The C API received support for dumping objects from ORCv2
(`rGcec8e69f01c3374cb38c6683058381b96fab8f89
<https://reviews.llvm.org/rGcec8e69f01c3374cb38c6683058381b96fab8f89>`_)
* A breaking change to ``LLVMOrcObjectTransformLayerTransformFunction`` was
introduced, changing the order of the function pointer's arguments.
(`rG8962c68ad007a525f9daa987c99eda57e0d0069a
<https://reviews.llvm.org/rG8962c68ad007a525f9daa987c99eda57e0d0069a>`_)
* The C API received support for accessing utilities from the LLJIT
``IRTransformLayer`` and ``ThreadSafeModule`` classes. (`D103855
<https://reviews.llvm.org/D103855>`_)
* The C API received support for creating lazy-export MaterializationUnits
(`D104672 <https://reviews.llvm.org/D104672>`_)
* The C API function ``LLVMPassBuilderOptionsSetCoroutines`` was removed because
couroutine passes have been enabled by default. (`D105877
<https://reviews.llvm.org/D105877>`_)
* ``comdat noduplicates`` was renamed to ``comdat nodeduplicate`` and as a
result, ``LLVMNoDuplicatesComdatSelectionKind`` was renamed to
``LLVMNoDeduplicateComdatSelectionKind``. (`D106319
<https://reviews.llvm.org/D106319>`_)
