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 bd8a1ce7bb [clang-format] [PR41170] Break after return type ignored with certain comments positions
Summary:
Addresses https://bugs.llvm.org/show_bug.cgi?id=41170

The AlwaysBreakAfterReturn type setting can go wrong if the line ends with a comment
```
void foo() /* comment */
```
or

```
void foo() // comment
```

It will incorrectly see such functions as Declarations and not Definitions

The following code addresses this by looking for function which end with `; <comment>` rather than just `;` or `<comment>`

Reuben Thomas 08a940d629 [clang-format]: Add NonEmptyParentheses spacing option
This patch aims to add support for the following rules from the JUCE coding standards:

- Always put a space before an open parenthesis that contains text - e.g. foo (123);
- Never put a space before an empty pair of open/close parenthesis - e.g. foo();

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.

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.

Adrian Prantl 9fc8faf9e6 Remove \brief commands from doxygen comments.
This is similar to the LLVM change https://reviews.llvm.org/D46290.

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.

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() {
       if (a) {
     }
     void g();
   Now:
     void f() {
       if (a) {

     void g();

Manuel Klimek 4fe43002f8 Makes whitespace management more consistent.
Instead of selectively storing some changes and directly generating
replacements for others, we now notify the WhitespaceManager of the
whitespace before every token (and optionally with more changes inside
tokens).

Then, we run over all whitespace in the very end in original source
order, where we have all information available to correctly align
comments and escaped newlines.

The future direction is to pull more of the comment alignment
implementation that is now in the BreakableToken into the
WhitespaceManager.

This fixes a bug when aligning comments or escaped newlines in unwrapped
lines that are handled out of order:
  #define A \
    f({     \
      g();  \
    });
... now gets correctly layouted.

Daniel Jasper f8114cf621 Cut-off clang-format analysis.
If clang-format is confronted with long and deeply nested lines (e.g.
complex static initializers or function calls), it can currently try too
hard to find the optimal solution and never finish. The reason is that
the memoization does not work effectively for deeply nested lines.

This patch removes an earlier workaround and instead opts for
accepting a non-optimal solution in rare cases. However, it only does
so only in cases where it would have to analyze an excessive number of
states (currently set to 10000 - the most complex line in Format.cpp
requires ~800 states) so this should not change the behavior in a
relevant way.

Daniel Jasper 8e35769b24 Change indentation when breaking after a type.
clang-format did not indent any declarations/definitions when breaking
after the type. With this change, it indents for all declarations but
does not indent for function definitions, i.e.:

Before:
const SomeLongTypeName&
some_long_variable_name;
typedef SomeLongTypeName
SomeLongTypeAlias;
const SomeLongReturnType*
SomeLongFunctionName();
const SomeLongReturnType*
SomeLongFunctionName() { ... }

After:
const SomeLongTypeName&
    some_long_variable_name;
typedef SomeLongTypeName
    SomeLongTypeAlias;
const SomeLongReturnType*
    SomeLongFunctionName();
const SomeLongReturnType*
SomeLongFunctionName() { ... }

While it might seem inconsistent to indent function declarations, but
not definitions, there are two reasons for that:
- Function declarations are very similar to declarations of function
type variables, so there is another side to consistency to consider.
- There can be many function declarations on subsequent lines and not
indenting can make them harder to identify. Function definitions
are already separated by their body and not indenting
makes the function name slighly easier to find.
