This document contains the release notes for the LLVM Compiler Infrastructure,
|
2020-01-15 10:02:56 +01:00
|
|
|
release 11.0.0. Here we describe the status of LLVM, including major improvements
|
2012-12-10 00:14:26 +01:00
|
|
|
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
|
2018-09-10 10:50:31 +02:00
|
|
|
from the `LLVM releases web site <https://llvm.org/releases/>`_.

.. 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.

subsection about it right here. You can copy the following boilerplate

|
|
|

and un-indent it (the indentation causes it to be inside this comment).

* The callsite attribute `vector-function-abi-variant
|
|
|
|
|
<https://llvm.org/docs/LangRef.html#call-site-attributes>`_ has been
|
|
|
|
|
added to describe the mapping between scalar functions and vector
|
|
|
|
|
functions, to enable vectorization of call sites. The information
|
|
|
|
|
provided by the attribute is interfaced via the API provided by the
|
|
|
|
|
``VFDatabase`` class.
