This patch applies clang-tidy's bugprone-argument-comment tool

Francois Ferrand e8a301f87f clang-format: better handle namespace macros
Summary:
Other macros are used to declare namespaces, and should thus be handled
similarly. This is the case for crpcut's TESTSUITE macro, or for
unittest-cpp's SUITE macro:

      TESTSUITE(Foo) {
      TEST(MyFirstTest) {
        assert(0);
      }
      } // TESTSUITE(Foo)

This patch deals with this cases by introducing a new option to specify
lists of namespace macros. Internally, it re-uses the system already in
place for foreach and statement macros, to ensure there is no impact on
performance.

Paul Hoad cbb726d0c5 [clang-format] Add basic support for formatting C# files
Summary:

This revision adds basic support for formatting C# files with clang-format, I know the barrier to entry is high here  so I'm sending this revision in to test the water as to whether this might be something we'd consider landing.

Tracking in Bugzilla as:
https://bugs.llvm.org/show_bug.cgi?id=40850

Justification:
C# code just looks ugly in comparison to the C++ code in our source tree which is clang-formatted.

I've struggled with Visual Studio reformatting to get a clean and consistent style, I want to format our C# code on saving like I do now for C++ and i want it to have the same style as defined in our .clang-format file, so it consistent as it can be with C++.  (Braces/Breaking/Spaces/Indent etc..)

Using clang format without this patch leaves the code in a bad state, sometimes when the BreakStringLiterals is set, it  fails to compile.

Mostly the C# is similar to Java, except instead of JavaAnnotations I try to reuse the TT_AttributeSquare.

Almost the most valuable portion is to have a new Language in order to partition the configuration for C# within a common .clang-format file, with the auto detection on the .cs extension. But there are other C# specific styles that could be added later if this is accepted. in particular how  `{ set;get }` is formatted.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
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.

Krasimir Georgiev 5528cace04 [clang-format] tweaked another case of lambda formatting
Summary:
This is done in order to improve cases where the lambda's body is moved too far to the right. Consider the following snippet with column limit set to 79:

```
void f() {
  leader::MakeThisCallHere(&leader_service_,
                           cq_.get(),
                           [this, liveness](const leader::ReadRecordReq& req,
                                            std::function<void()> done) {
                             logger_->HandleReadRecord(
                                 req, resp, std::move(done));
                           });

  leader::MakeAnother(&leader_service_,
                      cq_.get(),
                      [this, liveness](const leader::ReadRecordReq& req,
                                       std::function<void()> done) {
                        logger_->HandleReadRecord(
                            req, resp, std::move(done), a);
                      });
}
```

The tool favors extra indentation for the lambda body and so the code incurs extra wrapping and adjacent calls are indented to a different level. I find this behavior annoying and I'd like the tool to favor new lines and, thus, use the extra width.

The fix, reduced, brings the following formatting.

Before:

    function(1,
             [] {
               DoStuff();
               //
             },
             1);

After:

    function(
        1,
        [] {
          DoStuff();
          //
        },
        1);

Refer to the new tests in FormatTest.cpp

Sam McCall 6f3778c372 clang-format: Fix formatting C++ namespaces with preceding 'inline' or 'export' specifier
This fixes formatting namespaces with preceding 'inline' and 'export' (Modules TS) specifiers.

This change fixes namespaces not being identified as such with preceding 'inline' or 'export' specifiers.

Motivation: I was experimenting with the Modules TS (-fmodules-ts) and found it would be useful if clang-format would correctly format 'export namespace'. While making the changes, I noticed that similar issues still exist with 'inline namespace', and addressed them as well.

Manuel Klimek 0dddcf78b8 Format closing braces when reformatting the line containing the opening brace.
This required a couple of yaks to be shaved:
1. MatchingOpeningBlockLineIndex was misused to also store the
   closing index; instead, use a second variable, as this doesn't
   work correctly for "} else {".
2. We needed to change the API of AffectedRangeManager to not
   use iterators; we always passed in begin / end for the whole
   container before, so there was no mismatch in generality.
3. We need an extra check to discontinue formatting at the top
   level, as we now sometimes change the indent of the closing
   brace, but want to bail out immediately afterwards, for
   example:
     void f() {
       if (a) {
     }
     void g();
   Previously:
     void f() {

Krasimir Georgiev 3b0b50bac5 [clang-format] Fixed one-line if statement
Summary:
**Short overview:**

Fixed bug: https://bugs.llvm.org/show_bug.cgi?id=34001
Clang-format bug resulting in a strange behavior of control statements short blocks. Different flags combinations do not guarantee expected result. Turned on option AllowShortBlocksOnASingleLine does not work as intended.

**Description of the problem:**

Cpp source file UnwrappedLineFormatter does not handle AllowShortBlocksOnASingleLine flag as it should. Putting a single-line control statement without any braces, clang-format works as expected (depending on AllowShortIfStatementOnASingleLine or AllowShortLoopsOnASingleLine value). Putting a single-line control statement in braces, we can observe strange and incorrect behavior.
Our short block is intercepted by tryFitMultipleLinesInOne function. The function returns a number of lines to be merged. Unfortunately, our control statement block is not covered properly. There are several if-return statements, but none of them handles our block. A block is identified by the line first token and by left and right braces. A function block works as expected, there is such an if-return statement doing proper job. A control statement block, from the other hand, falls into strange conditional construct, which depends on BraceWrapping.AfterFunction flag (with condition that the line’s last token is left brace, what is possible in our case) or goes even further. That should definitely not happen.

**Description of the patch:**

By adding three different if statements, we guarantee that our short control statement block, however it looks like (different brace wrapping flags may be turned on), is handled properly and does not fall into wrong conditional construct. Depending on appropriate options we return either 0 (when something disturbs our merging attempt) or let another function (tryMergeSimpleBlock) take the responsibility of returned result (number of merged lines). Nevertheless, one more correction is required in mentioned tryMergeSimpleBlock function. The function, previously, returned either 0 or 2. The problem was that this did not handle the case when our block had the left brace in a separate line, not the header one. After change, after adding condition, we return the result compatible with block’s structure. In case of left brace in the header’s line we do everything as before the patch. In case of left brace in a separate line we do the job similar to the one we do in case of a “non-header left brace” function short block. To be precise, we try to merge the block ignoring the header line. Then, if success, we increment our returned result.

**After fix:**

**CONFIG:**
```
AllowShortBlocksOnASingleLine: true
AllowShortIfStatementsOnASingleLine: true
BreakBeforeBraces: Custom
BraceWrapping: {
AfterClass: true, AfterControlStatement: true, AfterEnum: true, AfterFunction: true, AfterNamespace: false, AfterStruct: true, AfterUnion: true, BeforeCatch: true, BeforeElse: true
}
```
**BEFORE:**
```
if (statement) doSomething();
if (statement) { doSomething(); }
if (statement) {
    doSomething();
}
if (statement)
{
    doSomething();
}
if (statement)
    doSomething();
if (statement) {
    doSomething1();
    doSomething2();
}
```
**AFTER:**
```

if (statement) { doSomething(); }
if (statement) { doSomething(); }
if (statement) { doSomething(); }
if (statement) doSomething();
if (statement)

The context of this patch is that I'm a VMware intern, and I implemented this because VMware needs the feature. As such, some decisions were made based on what VMware wants, and I would appreciate suggestions on expanding this if necessary to use-cases other people may want.

This adds a new enum config option, `IndentPPDirectives`. Values are:

* `PPDIS_None` (in config: `None`):
```
    #if FOO
    #if BAR
    #include <foo>
    #endif
    #endif
```
* `PPDIS_AfterHash` (in config: `AfterHash`):
```
    #if FOO
    #  if BAR
    #    include <foo>
    #  endif
    #endif
```
This is meant to work whether spaces or tabs are used for indentation. Preprocessor indentation is independent of indentation for non-preprocessor lines.

Preprocessor indentation also attempts to ignore include guards with the checks:
1. Include guards cover the entire file
2. Include guards don't have `#else`
3. Include guards begin with
```
#ifndef <var>
#define <var>
```

This patch allows `UnwrappedLineParser::PPBranchLevel` to be decremented to -1 (the initial value is -1) so the variable can be used for indent tracking.

Defects:
* This patch does not handle the case where there's code between the `#ifndef` and `#define` but all other conditions hold. This is because when the #define line is parsed, `UnwrappedLineParser::Lines` doesn't hold the previous code line yet, so we can't detect it. This is out of the scope of this patch.

* This patch does not handle cases where legitimate lines may be outside an include guard. Examples are `#pragma once` and `#pragma GCC diagnostic`, or anything else that does not change the meaning of the file if it's included multiple times.

* This does not detect when there is a single non-preprocessor line in front of an include-guard-like structure where other conditions hold because `ScopedLineState` hides the line.

* Preprocessor indentation throws off `TokenAnnotator::setCommentLineLevels` so the indentation of comments immediately before indented preprocessor lines is toggled on each run. Fixing this issue appears to be a major change and too much complexity for this patch.

Francois Ferrand a64ba70183 clang-format: merge short case labels with trailing comments
Summary:
Allow merging short case labels when they actually end with a comment
(like a comment after the ``break``) and when followed by switch-level
comments (e.g. aligned with next case):

  switch(a) {
  case 0: break; // comment at end of case
  case 1: return value;
  // comment related to next case
  // comment related to next case
  case 2:
  }

Francois Ferrand ad72256daa clang-format: add options to merge empty record body
Summary:
This patch introduces a few extra BraceWrapping options, similar to
`SplitEmptyFunction`, to allow merging empty 'record' bodies (e.g.
class, struct, union and namespace):
* SplitEmptyClass
* SplitEmptyStruct
* SplitEmptyUnion
* SplitEmptyNamespace

The `SplitEmptyFunction` option name has also been simplified/
shortened (from `SplitEmptyFunctionBody`).

These options are helpful when the correspond AfterXXX option is
enabled, to allow merging the empty record:

  class Foo
  {};

In addition, this fixes an unexpected merging of short records, when
the AfterXXXX options are used, which caused to be formatted like
this:

  class Foo
  { void Foo(); };

This is now properly formatted as:

  class Foo
  {
     void Foo();
  };

Francois Ferrand d3f0e3dee0 clang-format: introduce InlineOnly short function style
Summary:
This is the same as Inline, except it does not imply all empty
functions are merged: with this style, empty functions are merged only
if they also match the 'inline' criteria (i.e. defined in a class).

This is helpful to avoid inlining functions in implementations files.

With this option, consecutive namespace declarations are kept on the
same line:

  namespace foo { namespace bar {

Daniel Jasper 7d42f3f746 [clang-format] Refactor WhitespaceManager and friends
The main motivation behind this is to cleanup the WhitespaceManager and
make it more extensible for future alignment etc. features.
Specifically, WhitespaceManager has started to copy more and more code
that is already present in FormatToken. Instead, I think it makes more
sense to actually store a reference to each FormatToken for each change.

This has as a consequence led to a change in the calculation of indent
levels. Now, we actually compute them for each Token ahead of time,
which should be more efficient as it removes an unsigned value for the
ParenState, which is used during the combinatorial exploration of the
solution space.

No functional changes intended.

temporary solution, I need to look at this more closely a) to find a
fundamentally better approach and b) to look at whether the more recent
usage of NoLineBreak makes us visit stuff in an unfortunate order
where clang-format waste many states in dead ends.
