Changes to the AMDGPU Backend
-----------------------------
+* Initial support for gfx950
+
+* Improved ``llvm.memcpy``, ``llvm.memmove`` and ``llvm.memset`` lowering
+
+* Fixed expansion of 64-bit flat address space ``atomicrmw`` and
+ ``cmpxchg`` operations which may access private
+ memory. `noalias.addrspace` metadat may be used to avoid the
+ expansion if the target address is known to not be on the stack.
+
+* Fix compile failures when emitting unreachable functions.
+
* Removed `llvm.amdgcn.flat.atomic.fadd` and
`llvm.amdgcn.global.atomic.fadd` intrinsics. Users should use the
{ref}`atomicrmw <i_atomicrmw>` instruction with `fadd` and
