cc918e90c0 [clang-format] [PR33890] Add support for Microsoft C++/CLI non standard for each looping extension
Summary:
https://bugs.llvm.org/show_bug.cgi?id=33890

This revision allow the microsoft `for each(.... in ...` nonstandard C++ extension which can be used in C++/CLI to be handled as a ForEach macro.

This prevents the breaking between the for and each onto a new line

b99bf0e08b [clang-format][PR45816] Add AlignConsecutiveBitFields
Summary:
The following revision follows D80115 since @MyDeveloperDay and I apparently both had the same idea at the same time, for https://bugs.llvm.org/show_bug.cgi?id=45816 and my efforts on tooling support for AMDVLK, respectively.

This option aligns adjacent bitfield separators across lines, in a manner similar to AlignConsecutiveAssignments and friends.

Example:
```
struct RawFloat {
  uint32_t sign : 1;
  uint32_t exponent : 8;
  uint32_t mantissa : 23;
};
```
would become
```
struct RawFloat {
  uint32_t sign     : 1;
  uint32_t exponent : 8;
  uint32_t mantissa : 23;
};
```

This also handles c++2a style bitfield-initializers with AlignConsecutiveAssignments.
```
struct RawFloat {
  uint32_t sign     : 1  = 0;
  uint32_t exponent : 8  = 127;
  uint32_t mantissa : 23 = 0;
}; // defaults to 1.0f
```

Things this change does not do:
 - Align multiple comma-chained bitfield variables. None of the other
   AlignConsecutive* options seem to implement that either.
 - Detect bitfields that have a width specified with something other
   than a numeric literal (ie, `int a : SOME_MACRO;`). That'd be fairly
   difficult to parse and is rare.

e71c537a48 [clang-format] Fix line lengths w/ comments in align
Summary:
https://bugs.llvm.org/show_bug.cgi?id=43845

When a '//comment' trails a consecutive alignment, it adds a whitespace
replacement within the comment token. This wasn't handled correctly in
the alignment code, which treats it as a whole token and thus double
counts it.

This can wrongly trigger the "line too long, it'll wrap" alignment-break
condition with specific lengths, causing the alignment to break for
seemingly no reason.

clang-format leaves the code a little messy afterwards..

```
if (argc > 5)
  [[unlikely]] {
    // ...
  }
else if (argc < 0)
  [[likely]] {
    // ...
  }
else
  [[likely]] {
    // ...
  }
```

try to improve the situation

```
if (argc > 5) [[unlikely]] {
  // ...
} else if (argc < 0) [[likely]] {
  // ...
} else [[likely]] {
  // ...

575c59cf6a [clang-format] [PR45614] Incorrectly indents [[nodiscard]] attribute funtions after a macro without semicolon
Summary:
https://bugs.llvm.org/show_bug.cgi?id=45614

`[[nodiscard]]` after a macro doesn't behave the same as an __attribute__ resulting in incorrect indentation

This revision corrects that behavior

See original Mozilla bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=1629756

Before:

```
class FooWidget : public nsBaseWidget {
public:
  FooWidget();

  NS_DECL_ISUPPORTS_INHERITED

      [[nodiscard]] nsresult
      FunctionOne();
  [[nodiscard]] nsresult FunctionTwo();
};
```

After:
```
class FooWidget : public nsBaseWidget {
public:
  FooWidget();

  NS_DECL_ISUPPORTS_INHERITED

  [[nodiscard]] nsresult FunctionOne();
  [[nodiscard]] nsresult FunctionTwo();
};
```

6189dd06ad [clang-format] [PR45942] [[nodiscard]] causes && to be miss interpreted as BinaryOperators
Summary:
https://bugs.llvm.org/show_bug.cgi?id=45942

With Chromium style (although that is not important) its just it defines PointerAligmment: Left

The following arguments `S&&` are formatted differently depending on if the class has an attribute between it and the class identifier

```
class S {
  S(S&&) = default;
};

class [[nodiscard]] S {
  S(S &&) = default;
};
```

The prescense of [[nodiscard]] between the `class/struct` and the `{` causes the `{` to be incorrectly seen as a `TT_FunctionLBrace` which in turn transforms all the && to be `TT_BinaryOperators` rather than `TT_PointerOrReference`, as binary operators other spacing rules come into play causing a miss format

This revision resolves this by allowing the parseRecord to consider the [[nodisscard]]

e8ea35e63f [clang-format] [PR44345] Long namespace closing comment is duplicated endlessly
Summary:

When namespaces get long the namespace end comment wraps onto the next line

```

void bar();
} // namespace
  // would:🇮🇹:save::you:🅰️:lot::of::time::if_::i::just::gave:🆙:and_::went::mad::now

If clang-format it applied successively it will duplicate the end comment

    went::mad::now {

Even when BreakBeforeBinaryOperators is set, AlignOperands kept

actual operands (e.g. after an assignment).

With this patch, the operands are actually aligned, and the operator

  int aaaaa = bbbbbb
            + cccccc;

This not happen in tests, to avoid 'breaking' the indentation:

4db94094b4 clang-format: support aligned nested conditionals formatting
Summary:
When multiple ternary operators are chained, e.g. like an if/else-if/
else-if/.../else sequence, clang-format will keep aligning the colon
with the question mark, which increases the indent for each
conditionals:

  int a = condition1 ? result1
                     : condition2 ? result2
                                  : condition3 ? result3
                                               : result4;

This patch detects the situation (e.g. conditionals used in false branch
of another conditional), to avoid indenting in that case:

  int a = condition1 ? result1
        : condition2 ? result2
        : condition3 ? result3
                     : result4;

When BreakBeforeTernaryOperators is false, this will format like this:

  int a = condition1 ? result1 :
          condition2 ? result2 :
          conditino3 ? result3 :
                       result4;

b2eb439317 [clang-format] Fix AlignConsecutive on PP blocks
Summary:
Currently the 'AlignConsecutive*' options incorrectly align across
elif and else statements, even if they are very far away and across
unrelated preprocessor macros.

This failed since on preprocessor run 2+, there is not enough context
about the #ifdefs to actually differentiate one block from another,
causing them to align across different blocks or even large sections of
the file.

Eg, with AlignConsecutiveAssignments:

```
\#if FOO      // Run 1
\#else        // Run 1
int a   = 1;  // Run 2, wrong
\#endif       // Run 1

\#if FOO      // Run 1
\#else        // Run 1
int bar = 1;  // Run 2
\#endif       // Run 1
```

is read as

```
int a   = 1;  // Run 2, wrong
int bar = 1;  // Run 2
```

The approach taken to fix this was to add a new flag to Token that
forces breaking alignment across groups of lines (MustBreakAlignBefore)
in a similar manner to the existing flag that forces a line break
(MustBreakBefore). This flag is set for the first Token after a
preprocessor statement or diff conflict marker.

f21c704553 clang-format: Add ControlStatementsExceptForEachMacros option to SpaceBeforeParens
Summary: systemd recently added a clang-format file. One issue I
encountered in using clang-format on systemd is that systemd does
not add a space before the parens of their foreach macros but
clang-format always adds a space. This does not seem to be
configurable in clang-format. This revision adds the
ControlStatementsExceptForEachMacros option to SpaceBeforeParens
which puts a space before all control statement parens except
ForEach macros. This drastically reduces the amount of changes
when running clang-format on systemd's source code.

072ae7c1e6 [clang-format] Always break line after enum opening brace
Summary:
clang-format currently puts the first enumerator on the same line as the
enum keyword and opening brace if it fits (for example, for anonymous
enums if IndentWidth is 8):

  $ echo "enum { RED, GREEN, BLUE };" | clang-format -style="{BasedOnStyle: llvm, ColumnLimit: 15, IndentWidth: 8}"
  enum { RED,
         GREEN,
         BLUE };

This doesn't seem to be intentional, as I can't find any style guide that
suggests wrapping enums this way. Always force the enumerator to be on a new
line, which gets us the desired result:

  $ echo "enum { RED, GREEN, BLUE };" | ./bin/clang-format -style="{BasedOnStyle: llvm, ColumnLimit: 15, IndentWidth: 8}"
  enum {
          RED,
          GREEN,
          BLUE
  };

a324fcf1ae clang-format: insert trailing commas into containers.
Summary:
This change adds an option to insert trailing commas into container
literals. For example, in JavaScript:

    const x = [
      a,
      b,
       ^~~~~ inserted if missing.
    ]

This is implemented as a seperate post-processing pass after formatting
(because formatting might change whether the container literal does or
does not wrap). This keeps the code relatively simple and orthogonal,
though it has the notable drawback that the newly inserted comma is not
taken into account for formatting decisions (e.g. it might exceed the 80
char limit). To avoid exceeding the ColumnLimit, a comma is only
inserted if it fits into the limit.

Trailing comma insertion conceptually conflicts with argument
bin-packing: inserting a comma disables bin-packing, so we cannot do
both. clang-format rejects FormatStyle configurations that do both with
this change.

14c044756e [clang-format] Add IndentCaseBlocks option
Summary:
The documentation for IndentCaseLabels claimed that the "Switch
statement body is always indented one level more than case labels". This
is technically false for the code block immediately following the label.
Its closing bracket aligns with the start of the label.

If the case label are not indented, it leads to a style where the
closing bracket of the block aligns with the closing bracket of the
switch statement, which can be hard to parse.

This change introduces a new option, IndentCaseBlocks, which when true
treats the block as a scope block (which it technically is).

(Note: regenerated ClangFormatStyleOptions.rst using tools/dump_style.py)

33463cfba2 clang-format: fix spacing in operator const char*()
Summary:
Revision a75f8d98d7ac9e557b238a229a9a2647c71feed1 fixed spacing for operators,
but caused the const and non-const versions to diverge:
```
// With Style.PointerAlignment = FormatStyle::PAS_Left:

struct A {
  operator char*() { return ""; }
  operator const char *() const { return ""; }
};

```
The code was checking if the type specifier was directly preceded by `operator`.
However there could be comments and `const/volatile` in between.

d45aafa2fb [clang-format] fix conflict between FormatStyle::BWACS_MultiLine and BeforeCatch/BeforeElse
Summary:
Found a bug introduced with BraceWrappingFlags AfterControlStatement MultiLine. This feature conflicts with the existing BeforeCatch and BeforeElse flags.

For example, our team uses BeforeElse.

if (foo ||
    bar) {
  doSomething();
}
else {
  doSomethingElse();
}

If we enable MultiLine (which we'd really love to do) we expect it to work like this:

if (foo ||
    bar)
{
  doSomething();
}
else {
  doSomethingElse();
}

What we actually get is:

if (foo ||
    bar)
{
  doSomething();
}
else
{
  doSomethingElse();
}

Summary:
By additional regex match, grouping of main include can be enabled in files that are not normally considered as a C/C++ source code.
For example, this might be useful in templated code, where template implementations are being held in *Impl.hpp files.
On the occassion, 'assume-filename' option description was reworded as it was misleading. It has nothing to do with `style=file` option and it does not influence sourced style filename.

For context, I am looking into a related bug in the clang-formatting of
coroutine keywords: `co_yield -1;` is also reformatted in this manner
as `co_yield - 1;`. A later diff will add these changes and tests for the
`co_yield` and `co_return` keywords.
