Introduction

|
============
|
|
|
|
|
|
|
|
|
|
This document contains the release notes for the LLVM Compiler Infrastructure,
|
2017-01-13 05:50:22 +08:00
|
|
|
release 5.0.0. Here we describe the status of LLVM, including major improvements
|
2012-12-10 07:14:26 +08:00
|
|
|
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/>`_.
|
|
|
|
|
|
|
|
|
|

|
|
|

release, please check out the `main LLVM web site <http://llvm.org/>`_. If you
|
|
|
|
|
have questions or comments, the `LLVM Developer's Mailing List
|
2015-08-05 11:51:17 +08:00
|
|
|
<http://lists.llvm.org/mailman/listinfo/llvm-dev>`_ is a good place to send

|
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

Non-comprehensive list of changes in this release
|
|
|
|
|
=================================================
|
|
|
|
|
.. NOTE
|
|
|
|
|
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.
|
2012-12-10 07:14:26 +08:00
|
|
|
|
2017-05-09 03:15:06 +08:00
|
|
|
* LLVM's ``WeakVH`` has been renamed to ``WeakTrackingVH`` and a new ``WeakVH``
|
|
|
|
|
has been introduced. The new ``WeakVH`` nulls itself out on deletion, but
|
|
|
|
|
does not track values across RAUW.
|
2017-06-09 01:47:22 +08:00
|
|
|
|
|
|
|
|
* A new library named ``BinaryFormat`` has been created which holds a collection
|
|
|
|
|
of code which previously lived in ``Support``. This includes the
|
|
|
|
|
``file_magic`` structure and ``identify_magic`` functions, as well as all the
|
|
|
|
|
structure and type definitions for DWARF, ELF, COFF, WASM, and MachO file
|
|
|
|
|
formats.
|
|
|
|
|
|
2017-06-10 04:46:17 +08:00
|
|
|
* The tool ``llvm-pdbdump`` has been renamed ``llvm-pdbutil`` to better reflect
|
|
|
|
|
its nature as a general purpose PDB manipulation / diagnostics tool that does
|
|
|
|
|
more than just dumping contents.
|
|
|
|
|
|
2017-06-30 15:09:08 +08:00
|
|
|
* The ``BBVectorize`` pass has been removed. It was fully replaced and no
|
|
|
|
|
longer used back in 2014 but we didn't get around to removing it. Now it is
|
|
|
|
|
gone. The SLP vectorizer is the suggested non-loop vectorization pass.

|
|
|
.. NOTE
|
|
|
|
|
If you would like to document a larger change, then you can add a
|
|
|
|
|
subsection about it right here. You can copy the following boilerplate
|
|
|
|
|
and un-indent it (the indentation causes it to be inside this comment).

* Deprecated the ``LLVMAddBBVectorizePass`` interface since the ``BBVectorize``
|
|
|
|
|
pass has been removed. It is now a no-op and will be removed in the next
|
|
|
|
|
release. Use ``LLVMAddSLPVectorizePass`` instead to get the supported SLP
|
|
|
|
|
vectorizer.
