1 ====================== 2 LLVM 3.7 Release Notes 3 ====================== 4 5 .. contents:: 6 :local: 7 8 .. warning:: 9 These are in-progress notes for the upcoming LLVM 3.7 release. You may 10 prefer the `LLVM 3.6 Release Notes <http://llvm.org/releases/3.6.0/docs 11 /ReleaseNotes.html>`_. 12 13 14 Introduction 15 ============ 16 17 This document contains the release notes for the LLVM Compiler Infrastructure, 18 release 3.7. 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/>`_. 22 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.cs.uiuc.edu/mailman/listinfo/llvmdev>`_ is a good place to send 27 them. 28 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 32 page <http://llvm.org/releases/>`_. 33 34 Non-comprehensive list of changes in this release 35 ================================================= 36 37 .. NOTE 38 For small 1-3 sentence descriptions, just add an entry at the end of 39 this list. If your description won't fit comfortably in one bullet 40 point (e.g. maybe you would like to give an example of the 41 functionality, or simply have a lot to talk about), see the `NOTE` below 42 for adding a new subsection. 43 44 * The minimum required Visual Studio version for building LLVM is now 2013 45 Update 4. 46 47 * A new documentation page, :doc:`Frontend/PerformanceTips`, contains a 48 collection of tips for frontend authors on how to generate IR which LLVM is 49 able to effectively optimize. 50 51 * The DataLayout is no longer optional. All the IR level optimizations expects 52 it to be present and the API has been changed to use a reference instead of 53 a pointer to make it explicit. The Module owns the datalayout and it has to 54 match the one attached to the TargetMachine for generating code. 55 56 * ... next change ... 57 58 .. NOTE 59 If you would like to document a larger change, then you can add a 60 subsection about it right here. You can copy the following boilerplate 61 and un-indent it (the indentation causes it to be inside this comment). 62 63 Special New Feature 64 ------------------- 65 66 Makes programs 10x faster by doing Special New Thing. 67 68 Changes to the ARM Backend 69 -------------------------- 70 71 During this release ... 72 73 74 Changes to the MIPS Target 75 -------------------------- 76 77 During this release ... 78 79 80 Changes to the PowerPC Target 81 ----------------------------- 82 83 During this release ... 84 85 86 Changes to the OCaml bindings 87 ----------------------------- 88 89 During this release ... 90 91 92 External Open Source Projects Using LLVM 3.7 93 ============================================ 94 95 An exciting aspect of LLVM is that it is used as an enabling technology for 96 a lot of other language and tools projects. This section lists some of the 97 projects that have already been updated to work with LLVM 3.7. 98 99 * A project 100 101 102 Additional Information 103 ====================== 104 105 A wide variety of additional information is available on the `LLVM web page 106 <http://llvm.org/>`_, in particular in the `documentation 107 <http://llvm.org/docs/>`_ section. The web page also contains versions of the 108 API documentation which is up-to-date with the Subversion version of the source 109 code. You can access versions of these documents specific to this release by 110 going into the ``llvm/docs/`` directory in the LLVM tree. 111 112 If you have any questions or comments about LLVM, please feel free to contact 113 us via the `mailing lists <http://llvm.org/docs/#maillist>`_. 114 115
