+<li>Preliminary support for processors, such as the Cortex-A8 and Cortex-A9,
+that implement version 7 of the ARM architecture.  The ARM backend now
+supports both the Thumb2 and Advanced SIMD (Neon) instruction sets.
+These features are still somewhat experimental and subject to change.
+The Neon intrinsics, in particular, may change in future releases of LLVM.
