This indicates an intrinsic parameter is required to be a constant, and should not be replaced with a non-constant value. Add the attribute to all AMDGPU and generic intrinsics that comments indicate it should apply to. I scanned other target intrinsics, but I don't see any obvious comments indicating which arguments are intended to be only immediates. This breaks one questionable testcase for the autoupgrade. I'm unclear on whether the autoupgrade is supposed to really handle declarations which were never valid. The verifier fails because the attributes now refer to a parameter past the end of the argument list. llvm-svn: 355981

Introduction
|
|
============
|
|
|
|
This document contains the release notes for the LLVM Compiler Infrastructure,
|
|
release 9.0.0. 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 <https://llvm.org/releases/>`_.
|
|
|
|
For more information about LLVM, including information about the latest
|
|
release, please check out the `main LLVM web site <https://llvm.org/>`_. If you
|
|
have questions or comments, the `LLVM Developer's Mailing List
|
|
<https://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 <https://llvm.org/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.
|
|
|
|
* The optimizer will now convert calls to memcmp into a calls to bcmp in some
|
|
circumstances. Users who are building freestanding code (not depending on the
|
|
platform's libc) without specifying -ffreestanding may need to either pass
|
|
-fno-builtin-bcmp, or provide a bcmp function.
|
|
|
|
.. 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).

Changes to the LLVM IR

parameter is required to be a simple constant. This annotation must
|
|
be accurate to avoid possible miscompiles.
