Summary:
Add two new options,
AllowAllArgumentsOnNextLine and
AllowAllConstructorInitializersOnNextLine. These mirror the existing
AllowAllParametersOfDeclarationOnNextLine and allow me to support an
internal style guide where I work. I think this would be generally
useful, some have asked for it on stackoverflow:

Summary:
Sometime after 6.0.0 and the current trunk 9.0.0 the following code would be considered as objective C and not C++
Reported by: https://twitter.com/mattgodbolt/status/1096188576503644160
$ clang-format.exe test.h
Configuration file(s) do(es) not support Objective-C: C:\clang\build\.clang-format
--- test.h --
```
std::vector<std::pair<std::string,std::string>> C;
void foo()
{
for (auto && [A,B] : C)
{
std::string D = A + B;
}
}
```

rC355158 added an optional language parameter to getLLVMStyle(), but this parameter was not used in getPredefinedStyle(). Because unit tests directly specify the style, this codepath wasn't tested. Add an additional unit test for getStyle().

Summary:
getLLVMStyle() sets the default style, but doesn't take the language as a parameter, so can't set default parameters when they differ from C++. This change adds LanguageKind as an input to getLLVMStyle so that we can start doing that.
See D55964 as a motivation for this, where we want Tablegen to be formatted differently than C++.

Trailing comments are not always aligned properly when UseTab is set to Always.
Consider:
int a; // x
int bbbbbbbb; // x
With .clang-format:
---
Language: Cpp
BasedOnStyle: LLVM
UseTab: Always
...
The trailing comments of this code block should be aligned, but aren't
To align the first trailing comment it needs to insert 8 spaces. This should be
one tab plus six spaces. It skips the logic of the first partial tab in
FirstTabWidth (=2) + Style.TabWidth (=8) <= Spaces (=8) and only inserts one
tab. Proposed fix and test is attached.

What was happening is that the split penalty before `operator` was being set to
a smaller value by a prior if block. Moved checks around to fix this and added a
regression test.

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.

Summary:
r346756 refined clang-format to not treat the `[` in `asm (...: [] ..)` as an
ObjCExpr. However that's not enough, as we might have a comma-separated list of
such clobbers as in the newly added test.
This updates the detection to instead look at the Line's first token being `asm`
and not mark `[`-s as ObjCExprs in this case.

ClangFormat will recognize it as C++11 attribute syntax and put a space between 'arr' and first '[', like:

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);

This patch moves the virtual file system form clang to llvm so it can be
used by more projects.
Concretely the patch:
- Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
- Moves the corresponding unit test from clang to llvm.
- Moves the vfs namespace from clang::vfs to llvm::vfs.
- Formats the lines affected by this change, mostly this is the result of
the added llvm namespace.

Summary:
Some macros are used in the body of function, and actually contain the trailing semicolon: they should thus be automatically followed by a new line, and not get merged with the next line. This is for example the case with Qt's Q_UNUSED macro:
void foo(int a, int b) {
Q_UNUSED(a)
return b;
}
This patch deals with these cases by introducing a new option to specify list of statement macros. This re-uses the system already in place for foreach macros, to ensure there is no impact on performance.

'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.

Summary:
Bug was caused due to comments at the start of scope. For a code like:
```
int func() { //
int b;
int c;
}
```
the comment at the first line gets IndentAndNestingLevel (1,1) whereas
the following declarations get only (0,1) which prevents them from insertion
of a new scope. So, I changed the AlignTokenSequence to look at previous
*non-comment* token when deciding whether to introduce a new scope into
stack or not.

WebKit C++ style for object initialization is as follows:
Foo foo { bar };
Yet using clang-format -style=webkit changes this to:
Foo foo{ bar };
As there is no existing combination of rules that will ensure a space
before a braced list in this fashion, this patch adds a new
SpaceBeforeCpp11BracedList rule.

Summary:
This option replaces the BreakBeforeInheritanceComma option with an
enum, thus introducing a mode where the colon stays on the same line as
constructor declaration:
// When it fits on line:
class A : public B, public C {
...
};
// When it does not fit:
class A :
public B,
public C {
...
};
This matches the behavior of the `BreakConstructorInitializers` option,
introduced in https://reviews.llvm.org/D32479.

Summary:
Introduce `PenaltyBreakTemplateDeclaration` to control the penalty,
and change `AlwaysBreakTemplateDeclarations` to an enum with 3 modes:
* `No` for regular, penalty based, wrapping of template declaration
* `MultiLine` for always wrapping before multi-line declarations (e.g.
same as legacy behavior when `AlwaysBreakTemplateDeclarations=false`)
* `Yes` for always wrapping (e.g. same as legacy behavior when
`AlwaysBreakTemplateDeclarations=true`)

Summary:
This patch changes the behavior of PenaltyBreakBeforeFirstCallParameter
so that is does not apply after a brace, when Cpp11BracedListStyle is
false.
This way, variable initialization is wrapped more like an initializer
than like a function call, which is more consistent with user
expectations for this braced list style.
With PenaltyBreakBeforeFirstCallParameter=200, this gives the following
code: (with Cpp11BracedListStyle=false)
Before :
const std::unordered_map<std::string, int> Something::MyHashTable =
{ { "aaaaaaaaaaaaaaaaaaaaa", 0 },
{ "bbbbbbbbbbbbbbbbbbbbb", 1 },
{ "ccccccccccccccccccccc", 2 } };
After :
const std::unordered_set<std::string> Something::MyUnorderedSet = {
{ "aaaaaaaaaaaaaaaaaaaaa", 0 },
{ "bbbbbbbbbbbbbbbbbbbbb", 1 },
{ "ccccccccccccccccccccc", 2 }
};

The DEBUG() macro is very generic so it might clash with other projects.
The renaming was done as follows:
- git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g'
- git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM
Explicitly avoided changing the strings in the clang-format tests.

Summary:
This diff improves the Objective-C guessing heuristic by
replacing the hard-coded list of a subset of Objective-C @keywords
with a general check which supports all @keywords.
I also added a few more Foundation keywords which were missing from
the heuristic.

Summary:
Currently, indentation of Objective-C method names which are wrapped
onto the next line due to a long return type is controlled by the
style option `IndentWrappedFunctionNames`.
This diff changes the behavior so we always indent wrapped Objective-C
selector names.
NOTE: I partially reverted https://github.com/llvm-mirror/clang/commit/6159c0fbd1876c7f5f984b4830c664cc78f16e2e / rL242484, as it was causing wrapped selectors to be double-indented. Its tests in FormatTestObjC.cpp still pass.

Previously, we would format:
int a() { ... }
[[unused]] int b() { ... }
as...
int a() {} [[unused] int b() {}
Now we correctly format each on its own line.
Similarly, we would detect:
[[unused]] int b() { return 42; }
As a lambda and leave it on a single line, even if that was disallowed
by the format style.

Summary: Extend various verifyFormat helper functions to check that the
expected text is "stable". This provides some protection against bugs
where formatting results are ocilating between two forms, or continually
change in some other way.
Testing Done:
* Ran unit tests.
* Reproduced a known instability in preprocessor indentation which was
caught by this new check.

Summary:
The following C++ code was being detected by
`guessLanguage()` as Objective-C:
#define FOO(...) auto bar = [] __VA_ARGS__;
This was because `[] __VA_ARGS__` is not currently detected as a C++
lambda expression (it has no parens or braces), so
`TokenAnnotator::parseSquare()` incorrectly treats the opening square
as an ObjC method expression.
We have two options to fix this:
1. Parse `[] __VA_ARGS__` explicitly as a C++ lambda
2. Make it so `[]` is never parsed as an Objective-C method expression
This diff implements option 2, which causes the `[` to be parsed
as `TT_ArraySubscriptLSquare` instead of `TT_ObjCMethodExpr`.
Note that when I fixed this, it caused one change in formatting
behavior, where the following was implicitly relying on the `[`
being parsed as `TT_ObjCMethodExpr`:
A<int * []> a;
becomes:
A<int *[]> a;
with `Style.PointerAlignment = Middle`.
I don't really know what the desired format is for this syntax; the
test was added by Janusz Sobczak and integrated by @djasper in
https://github.com/llvm-mirror/clang/commit/b511fe9818829d7ece0cc0b2ce1fbe04a1f0739a
.
I went ahead and changed the test for now.

Summary:
This fixes an issue brought up by djasper@ in his review of D44790. We
handled top-level child lines, but if those child lines themselves
had child lines, we didn't handle them.
Rather than use recursion (which could blow out the stack), I use a
DenseSet to hold the set of lines we haven't yet checked (since order
doesn't matter), and update the set to add the children of each
line as we check it.
Test Plan: New tests added. Confirmed tests failed before fix
and passed after fix.

Summary:
When I wrote `ObjCHeaderStyleGuesser`, I incorrectly assumed the
correct way to iterate over all tokens in `AnnotatedLine` was to
iterate over the linked list tokens starting with
`AnnotatedLine::First`.
However, `AnnotatedLine` also contains a vector
`AnnotedLine::Children` with child `AnnotedLine`s which have their own
tokens which we need to iterate over.
Because I didn't iterate over the tokens in the children lines, the
ObjC style guesser would fail on syntax like:
#define FOO ({ NSString *s = ... })
as the statement(s) inside { ... } are child lines.
This fixes the bug and adds a test. I confirmed the test
failed before the fix, and passed after the fix.
Test Plan: New tests added. Ran tests with:

For multiline raw string literals, we generally want to respect the
author's choice of linebreak before the 'R"(' as the rest of the raw
string might be aligned to it and we cannot (commonly) modify the
content.
For single-line raw string literals, this doesn't make any sense and so
we should just treat them as regular string literals in this regard.
