Braces around single-line statement inside control flow statement body is
occasionally not welcome in LLVM Codebase.
There are actually both many braces around single-line statement inside cfs
body here and many cfs's without braces around single-line body inside a single
file, which isn't good in terms of consistency at least inside the project.

This patch is just a mess, because I tried to push everything at once while most of the stuff is not related to clang-refactor part at all. I pushed 3 very basic cleanup patches (namely https://reviews.llvm.org/rL280638, https://reviews.llvm.org/rL280639 and https://reviews.llvm.org/rL280640), which don't really need reviewing (and also for the sake of development speed). And I also kept clang-rename improvements separate in https://reviews.llvm.org/D24224, which is up for review. I'll update this patch tomorrow. What I'm about to do after is to either: 1. Make two patches, one of which would basically create "empty" `clang-refactor` and introduce dummy submodule to show how it works (as you proposed), and the other would merge `clang-rename` as a submodule. 2. Make one patch, which both creates `clang-refactor` binary and merges `clang-rename` as a submodule. The first variant seems better to me while I see a couple of issues with that, which makes sticking to the second variant a bit less challenging. We can discuss it tomorr..today and come up with a solution.

Pls, double check me. Sorry, can you please elaborate? Also, this might be unrelated to this exact patch, but if there is an issue it's good to fix it in another patch.

[PATCH] D24224: [clang-rename] Merge rename-{ at | all } and optimise USRFindingAction.
omtcyfz created this revision.
omtcyfz added reviewers: alexfh, ioeric, vmiklos.
omtcyfz added subscribers: cfe-commits, Eugene.Zelenko.
Having both rename-at and rename-all both seems confusing and introduces
unneeded difficulties. Allowing to use both -qualified-name and -offset at once
while performing efficient renamings seems like a feature, too. Maintaining
`main` function wrappers and custom `help` becomes redundant while CLI becomes
less confusing.
This is basically D23651 done right.
This patch belongs to a sequence of patches needed for painless migration to
clang-refactor, see D24192.

[clang-tools-extra] r280640 - [clang-rename] Enforce LLVM policy about braces around single line control flow statement body.
Author: omtcyfz
Date: Sun Sep 4 17:50:41 2016
New Revision: 280640
URL: http://llvm.org/viewvc/llvm-project?rev=280640&view=rev
Log:
[clang-rename] Enforce LLVM policy about braces around single line control flow
statement body.
Although it is not explicitly stated in LLVM Coding Standards, LLVM developers
prefer to omit braces around flow control statements with single line body.
For example the following piece of code
```
if (condition)
std::cout << "Hello, world!" << std::endl;
```
is preferred to
```
if (condition) {
std::cout << "Hello, world!" << std::endl;
}
```
So far clang-rename has ignored this. This patch makes clang-rename more
"LLVM-ish".

r280635 - [AVX-512] Remove 128-bit and 256-bit masked floating point add/sub/mul/div builtins and replace with native operations.
Author: ctopper

Log:
[AVX-512] Remove 128-bit and 256-bit masked floating point add/sub/mul/div
builtins and replace with native operations.
We can't do the 512-bit ones because they take a rounding mode argument that we
can't represent.

There are still downstream consumers of 3.8, so merging fixes generally make it easier for them.

[libcxx] r280621 - [libcxx] Fix a data race in call_once

Log:
[libcxx] Fix a data race in call_once
call_once is using relaxed atomic load to perform double-checked locking, which
contains a data race. The fast-path load has to be an acquire atomic load.
