14Introduction
15============
16
17This document contains the release notes for the LLVM Compiler Infrastructure,
18release 3.5.  Here we describe the status of LLVM, including major improvements
19from the previous release, improvements in various subprojects of LLVM, and
20some of the current users of the code.  All LLVM releases may be downloaded
21from the `LLVM releases web site <http://llvm.org/releases/>`_.
22
23For more information about LLVM, including information about the latest
24release, please check out the `main LLVM web site <http://llvm.org/>`_.  If you
25have questions or comments, the `LLVM Developer's Mailing List
26<http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev>`_ is a good place to send
27them.

29Note that if you are reading this file from a Subversion checkout or the main
30LLVM web page, this document applies to the *next* release, not the current
31one.  To see the release notes for a specific release, please see the `releases
32page <http://llvm.org/releases/>`_.

34Non-comprehensive list of changes in this release
35=================================================
36
37* All backends have been changed to use the MC asm printer and support for the
38  non MC one has been removed.
39
40* The ARM back-end now has the EHABI exception handling enabled by default. Use
41  `-arm-disable-ehabi` to turn it off (both landing pads and unwind tables).
42
43* Clang can now successfully self-host itself on Linux/Sparc64 and on
44  FreeBSD/Sparc64.
45
46* LLVM now assumes the assembler supports ``.loc`` for generating debug line
47  numbers. The old support for printing the debug line info directly was only
48  used by ``llc`` and has been removed.
49
50.. NOTE
51   For small 1-3 sentence descriptions, just add an entry at the end of
52   this list. If your description won't fit comfortably in one bullet
53   point (e.g. maybe you would like to give an example of the
54   functionality, or simply have a lot to talk about), see the `NOTE` below
55   for adding a new subsection.
56
57* ... next change ...
58
59.. NOTE
60   If you would like to document a larger change, then you can add a
61   subsection about it right here. You can copy the following boilerplate
62   and un-indent it (the indentation causes it to be inside this comment).

69External Open Source Projects Using LLVM 3.5
70============================================
71
72An exciting aspect of LLVM is that it is used as an enabling technology for
73a lot of other language and tools projects. This section lists some of the
74projects that have already been updated to work with LLVM 3.5.

77Additional Information

80A wide variety of additional information is available on the `LLVM web page
81<http://llvm.org/>`_, in particular in the `documentation
82<http://llvm.org/docs/>`_ section.  The web page also contains versions of the
83API documentation which is up-to-date with the Subversion version of the source
