Summary:
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.
Patch produced by
for i in $(git grep -l '\\brief'); do perl -pi -e 's/\\brief //g' $i & done
[This is analogous to LLVM r331272 and CFE r331834]

Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

Summary:
If there is no comment, place it at the closing brace of a namespace
definition. Previously it was placed at the next character after the
closing brace.
The new position produces a better location for highlighting in clangd
and does not seem to make matters worse for clang-tidy.

Summary:
Finds non-static member functions that can be made ``static``.
I have run this check (repeatedly) over llvm-project. It made 1708 member functions
``static``. Out of those, I had to exclude 22 via ``NOLINT`` because their address
was taken and stored in a variable of pointer-to-member type (e.g. passed to
llvm::StringSwitch).
It also made 243 member functions ``const``. (This is currently very conservative
to have no false-positives and can hopefully be extended in the future.)

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

When a warning is issued in a template instantiation, the check would previously
use template arguments in a note, which would result in inconsistent or

Removed the uses of the allOf() matcher inside node matchers that are implicit

Summary:
This patch introduces a new clang-tidy check that matches on all `declStmt` that declare more then one variable
and transform them into one statement per declaration if possible.
It currently only focusses on variable declarations but should be extended to cover more kinds of declarations in the future.
It is related to https://reviews.llvm.org/D27621 and does use it's extensive test-suite. Thank you to firolino for his work!

This is a re-commit, the original was reverted by me in

Tests were added, and the bugs were fixed.
I'm unable to find any further bugs, hopefully there aren't any..

Summary:
The goal is to reduce false positives when the difference is intentional, like:
foo(StringRef name);
foo(StringRef name_ref) {
string name = cleanup(name_ref);
...
}
Or semantically unimportant, like:
foo(StringRef full_name);
foo(StringRef name) { ... }
There are other matching names we won't recognise (e.g. syns vs synonyms) but
this catches many that we see in practice, and gives people a systematic
workaround.
The old behavior is available as a 'Strict' option.
