14Introduction
15============
16
17This document contains the release notes for the LLVM Compiler Infrastructure,
18release 8.0.0.  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 <https://llvm.org/releases/>`_.
22
23For more information about LLVM, including information about the latest
24release, please check out the `main LLVM web site <https://llvm.org/>`_.  If you
25have questions or comments, the `LLVM Developer's Mailing List
26<https://lists.llvm.org/mailman/listinfo/llvm-dev>`_ 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 <https://llvm.org/releases/>`_.

34Non-comprehensive list of changes in this release
35=================================================
36.. NOTE
37   For small 1-3 sentence descriptions, just add an entry at the end of
38   this list. If your description won't fit comfortably in one bullet
39   point (e.g. maybe you would like to give an example of the
40   functionality, or simply have a lot to talk about), see the `NOTE` below
41   for adding a new subsection.
42
43* The **llvm-cov** tool can now export lcov trace files using the
44  `-format=lcov` option of the `export` command.
45
46* The add_llvm_loadable_module CMake macro has been removed.  The
47  add_llvm_library macro with the MODULE argument now provides the same
48  functionality.  See `Writing an LLVM Pass
49  <WritingAnLLVMPass.html#setting-up-the-build-environment>`_.
50
51.. NOTE
52   If you would like to document a larger change, then you can add a
53   subsection about it right here. You can copy the following boilerplate
54   and un-indent it (the indentation causes it to be inside this comment).
