-* The CellSPU port has been removed.  It can still be found in older versions.
+* Support for exception handling has been removed from the old JIT. Use MCJIT

-* The IR-level extended linker APIs (for example, to link bitcode files out of

-  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.
-
-* TargetTransformInfo (TTI) is a new interface that can be used by IR-level
-  passes to obtain target-specific information, such as the costs of
-  instructions. Only "Lowering" passes such as LSR and the vectorizer are
-  allowed to use the TTI infrastructure.
-
-* We've improved the X86 and ARM cost model.
-
-* The Attributes classes have been completely rewritten and expanded. They now
-  support not only enumerated attributes and alignments, but "string"
-  attributes, which are useful for passing information to code generation. See
-  :doc:`HowToUseAttributes` for more details.
-
-* TableGen's syntax for instruction selection patterns has been simplified.
-  Instead of specifying types indirectly with register classes, you should now
-  specify types directly in the input patterns. See ``SparcInstrInfo.td`` for
-  examples of the new syntax. The old syntax using register classes still
-  works, but it will be removed in a future LLVM release.
-
-* MCJIT now supports exception handling. Support for it in the old jit will be
-  removed in the 3.4 release.
-
-* Command line options can now be grouped into categories which are shown in
-  the output of ``-help``. See :ref:`grouping options into categories`.
-
-* The appearance of command line options in ``-help`` that are inherited by
-  linking with libraries that use the LLVM Command line support library can now
-  be modified at runtime. See :ref:`cl::getRegisteredOptions`.

    Makes programs 10x faster by doing Special New Thing.
 
-AArch64 target
---------------
-
-We've added support for AArch64, ARM's 64-bit architecture. Development is still
-in fairly early stages, but we expect successful compilation when:
-
-- compiling standard compliant C99 and C++03 with Clang;
-- using Linux as a target platform;
-- where code + static data doesn't exceed 4GB in size (heap allocated data has
-  no limitation).
-
-Some additional functionality is also implemented, notably DWARF debugging,
-GNU-style thread local storage and inline assembly.
-
-Hexagon Target
---------------
-
-- Removed support for legacy hexagonv2 and hexagonv3 processor
-  architectures which are no longer in use. Currently supported
-  architectures are hexagonv4 and hexagonv5.
 
-Loop Vectorizer
----------------
-
-We've continued the work on the loop vectorizer. The loop vectorizer now
-has the following features:
-
-- Loops with unknown trip counts.
-- Runtime checks of pointers.
-- Reductions, Inductions.
-- Min/Max reductions of integers.
-- If Conversion.
-- Pointer induction variables.
-- Reverse iterators.
-- Vectorization of mixed types.
-- Vectorization of function calls.
-- Partial unrolling during vectorization.
-
-The loop vectorizer is now enabled by default for -O3.
-
-SLP Vectorizer
---------------
-
-LLVM now has a new SLP vectorizer. The new SLP vectorizer is not enabled by
-default but can be enabled using the clang flag -fslp-vectorize. The BB-vectorizer
-can also be enabled using the command line flag -fslp-vectorize-aggressive.
-
-R600 Backend
-------------
-
-The R600 backend was added in this release, it supports AMD GPUs
-(HD2XXX - HD7XXX).  This backend is used in AMD's Open Source
-graphics / compute drivers which are developed as part of the `Mesa3D
-<http://www.mesa3d.org>`_ project.
-
-SystemZ/s390x Backend
----------------------
-
-LLVM and clang now support IBM's z/Architecture.  At present this support
-is restricted to GNU/Linux (GNU triplet s390x-linux-gnu) and requires
-z10 or greater.
-
-
-Sub-project Status Update
-============================================
-
-In addition to the core LLVM 3.3 distribution of production-quality compiler
-infrastructure, the LLVM project includes sub-projects that use the LLVM core
-and share the same distribution license.  This section provides updates on
-these sub-projects.
-
-
-LLDB: Low Level Debugger
-------------------------
-
-`LLDB <http://lldb.llvm.org/>`_ is a ground-up implementation of a command-line
-debugger, as well as a debugger API that can be used from scripts and other
-applications. LLDB uses the following components of the LLVM core distribution
-to support the latest language features and target support:
-
-- the Clang parser for high-quality parsing of C, C++ and Objective C
-- the LLVM disassembler
-- the LLVM JIT compiler (MCJIT) for expression evaluation
-
-The `3.3 release <http://llvm.org/apt/>`_ has the following notable changes.
-
-Linux Features:
-
-- Support for watchpoints
-- vim integration for lldb commands and program status using a `vim plug-in <http://llvm.org/svn/llvm-project/lldb/trunk/utils/vim-lldb/README>`_
-- Improved register support including vector registers
-- Builds with cmake/ninja/auto-tools/clang 3.3/gcc 4.6
-
-Linux Improvements:
-
-- Debugging multi-threaded programs
-- Debugging i386 programs
-- Process list, attach and fork
-- Expression evaluation

-External Open Source Projects Using LLVM 3.3
+External Open Source Projects Using LLVM 3.4
 ============================================
 
 An exciting aspect of LLVM is that it is used as an enabling technology for
 a lot of other language and tools projects. This section lists some of the
-projects that have already been updated to work with LLVM 3.3.
-
-
-Portable Computing Language (pocl)
-----------------------------------
-
-In addition to producing an easily portable open source OpenCL
-implementation, another major goal of `pocl <http://pocl.sourceforge.net/>`_ 
-is improving performance portability of OpenCL programs with
-compiler optimizations, reducing the need for target-dependent manual
-optimizations. An important part of pocl is a set of LLVM passes used to
-statically parallelize multiple work-items with the kernel compiler, even in
-the presence of work-group barriers. This enables static parallelization of
-the fine-grained static concurrency in the work groups in multiple ways.
-
-TTA-based Co-design Environment (TCE)
--------------------------------------
-
-`TCE <http://tce.cs.tut.fi/>`_ is a toolset for designing new 
-processors based on the Transport triggered architecture (TTA). 
-The toolset provides a complete co-design flow from C/C++
-programs down to synthesizable VHDL/Verilog and parallel program binaries.
-Processor customization points include the register files, function units,
-supported operations, and the interconnection network.
-
-TCE uses Clang and LLVM for C/C++/OpenCL C language support, target independent
-optimizations and also for parts of code generation. It generates new
-LLVM-based code generators "on the fly" for the designed TTA processors and
-loads them in to the compiler backend as runtime libraries to avoid
-per-target recompilation of larger parts of the compiler chain.
-
-Just-in-time Adaptive Decoder Engine (Jade)
--------------------------------------------
-
-`Jade <https://github.com/orcc/jade>`_ (Just-in-time Adaptive Decoder Engine)
-is a generic video decoder engine using LLVM for just-in-time compilation of
-video decoder configurations. Those configurations are designed by MPEG
-Reconfigurable Video Coding (RVC) committee. MPEG RVC standard is built on a
-stream-based dataflow representation of decoders. It is composed of a standard
-library of coding tools written in RVC-CAL language and a dataflow
-configuration --- block diagram --- of a decoder.
-
-Jade project is hosted as part of the Open RVC-CAL Compiler
-(`Orcc <http://orcc.sf.net>`_) and requires it to translate the RVC-CAL standard
-library of video coding tools into an LLVM assembly code.
-
-LDC - the LLVM-based D compiler
--------------------------------
-
-`D <http://dlang.org>`_ is a language with C-like syntax and static typing. It
-pragmatically combines efficiency, control, and modeling power, with safety and
-programmer productivity. D supports powerful concepts like Compile-Time Function
-Execution (CTFE) and Template Meta-Programming, provides an innovative approach
-to concurrency and offers many classical paradigms.
-
-`LDC <http://wiki.dlang.org/LDC>`_ uses the frontend from the reference compiler
-combined with LLVM as backend to produce efficient native code. LDC targets
-x86/x86_64 systems like Linux, OS X and Windows and also Linux/PPC64. Ports to
-other architectures like ARM are underway.
