-* The CellSPU port has been removed. It can still be found in older versions.
-
-* The IR-level extended linker APIs (for example, to link bitcode files out of
- archives) have been removed. Any existing clients of these features should
- move to using a linker with integrated LTO support.
-
-* LLVM and Clang's documentation has been migrated to the `Sphinx
- <http://sphinx-doc.org/>`_ documentation generation system which uses
- easy-to-write reStructuredText. See `llvm/docs/README.txt` for more
- information.

- Loop Vectorizer
- ---------------
- We've continued the work on the loop vectorizer. The loop vectorizer now has the following features:
- # Loops with unknown trip count.
- # Runtime checks of pointers
- # Reductions, Inductions
- # If Conversion
- # Pointer induction variables
- # Reverse iterators
- # Vectorization of mixed types
- # Vectorization of function calls
- # Partial unrolling during vectorization
-
- We've also improved the X86 and ARM cost model.
