Introduction
|
|
============
|
|
|
|
This document contains the release notes for the LLVM Compiler Infrastructure,
|
|
release 7.0.0. Here we describe the status of LLVM, including major improvements
|
|
from the previous release, improvements in various subprojects of LLVM, and
|
|
some of the current users of the code. All LLVM releases may be downloaded
|
|
from the `LLVM releases web site <http://llvm.org/releases/>`_.
|
|
|
|
For more information about LLVM, including information about the latest
|
|
release, please check out the `main LLVM web site <http://llvm.org/>`_. If you
|
|
have questions or comments, the `LLVM Developer's Mailing List
|
|
<http://lists.llvm.org/mailman/listinfo/llvm-dev>`_ is a good place to send
|
|
them.
|
|
|
|
Note that if you are reading this file from a Subversion checkout or the main
|
|
LLVM web page, this document applies to the *next* release, not the current
|
|
one. To see the release notes for a specific release, please see the `releases
|
|
page <http://llvm.org/releases/>`_.

For small 1-3 sentence descriptions, just add an entry at the end of
|
|
this list. If your description won't fit comfortably in one bullet
|
|
point (e.g. maybe you would like to give an example of the
|
|
functionality, or simply have a lot to talk about), see the `NOTE` below
|
|
for adding a new subsection.

.. NOTE
|
|
If you would like to document a larger change, then you can add a
