17 This document contains the release notes for the LLVM Compiler Infrastructure,
18 release 3.8. Here we describe the status of LLVM, including major improvements
19 from the previous release, improvements in various subprojects of LLVM, and
20 some of the current users of the code. All LLVM releases may be downloaded
21 from the `LLVM releases web site <http://llvm.org/releases/>`_.
23 For more information about LLVM, including information about the latest
24 release, please check out the `main LLVM web site <http://llvm.org/>`_. If you
25 have questions or comments, the `LLVM Developer's Mailing List
26 <http://lists.llvm.org/mailman/listinfo/llvm-dev>`_ is a good place to send
29 Note that if you are reading this file from a Subversion checkout or the main
30 LLVM web page, this document applies to the *next* release, not the current
31 one. To see the release notes for a specific release, please see the `releases

34 Non-comprehensive list of changes in this release
35 =================================================
36 * With this release, the minimum Windows version required for running LLVM is
37 Windows 7. Earlier versions, including Windows Vista and XP are no longer
40 * With this release, the autoconf build system is deprecated. It will be removed
41 in the 3.9 release. Please migrate to using CMake. For more information see:
42 `Building LLVM with CMake <CMake.html>`_
44 * The C API function LLVMLinkModules is deprecated. It will be removed in the
45 3.9 release. Please migrate to LLVMLinkModules2. Unlike the old function the
48 * Doesn't take an unused parameter.
49 * Destroys the source instead of only damaging it.
50 * Does not record a message. Use the diagnostic handler instead.
52 * The C API functions LLVMParseBitcode, LLVMParseBitcodeInContext,
53 LLVMGetBitcodeModuleInContext and LLVMGetBitcodeModule have been deprecated.
54 They will be removed in 3.9. Please migrate to the versions with a 2 suffix.
55 Unlike the old ones the new ones do not record a diagnostic message. Use
56 the diagnostic handler instead.
58 * The deprecated C APIs LLVMGetBitcodeModuleProviderInContext and
59 LLVMGetBitcodeModuleProvider have been removed.
61 * With this release, the C API headers have been reorganized to improve build
62 time. Type specific declarations have been moved to Type.h, and error
63 handling routines have been moved to ErrorHandling.h. Both are included in
64 Core.h so nothing should change for projects directly including the headers,
65 but transitive dependencies may be affected.
68 For small 1-3 sentence descriptions, just add an entry at the end of
69 this list. If your description won't fit comfortably in one bullet
70 point (e.g. maybe you would like to give an example of the
71 functionality, or simply have a lot to talk about), see the `NOTE` below
72 for adding a new subsection.
77 If you would like to document a larger change, then you can add a
78 subsection about it right here. You can copy the following boilerplate
79 and un-indent it (the indentation causes it to be inside this comment).

113 External Open Source Projects Using LLVM 3.8
114 ============================================
116 An exciting aspect of LLVM is that it is used as an enabling technology for
117 a lot of other language and tools projects. This section lists some of the
118 projects that have already been updated to work with LLVM 3.8.
123 Additional Information
124 ======================
126 A wide variety of additional information is available on the `LLVM web page
127 <http://llvm.org/>`_, in particular in the `documentation
128 <http://llvm.org/docs/>`_ section. The web page also contains versions of the
129 API documentation which is up-to-date with the Subversion version of the source
