Summary:
This patch adds tooling::deduplicate() which removes duplicates from and
looks for conflicts in a vector of Replacements.

In particular, left braces after an enum declaration now occur on their
own line. Further, when short ifs/whiles are allowed these no longer
cause the left brace to be on the same line as the if/while when a
brace is included.

This removes a formatting choice that was added at one point, but is
not generally liked by users. Specifically, in builder-type calls, do
(easily) break if the object before the ./-> is either a field or a
parameter-less function call. I.e., don't break after "aa.aa.aa" or
"aa.aa.aa()". In general, these sequences in builder-type calls are
seen as a single entity and thus breaking them up is a bad idea.

- pull out function to drill to the CXXRecordDecl from the type,
to allow recursive resolution
- make the analysis more robust by rather skipping values we don't
understand

Before, clang-format would not break overly long string literals
following a "<<" with FormatStyle::AlwaysBreakBeforeMultilineStrings
being set.

This unifies the unix and windows versions of FileManager::UniqueDirContainer
and FileManager::UniqueFileContainer by using UniqueID.
We cannot just replace "struct stat" with llvm::sys::fs::file_status, since we
want to be able to construct fake ones, and file_status has different members
on unix and windows.
What the patch does is:
* Record only the information that clang is actually using.
* Use llvm::sys::fs::status instead of stat and fstat.
* Use llvm::sys::fs::UniqueID
* Delete the old windows versions of UniqueDirContainer and
UniqueFileContainer since the "unix" one now works on windows too.

Before:
template <bool B, bool C>
class A {
static_assert(B &&C, "Something is wrong");
};
After:
template <bool B, bool C>
class A {
static_assert(B && C, "Something is wrong");
};
(Note the spacing around '&&'). Also change the identifier table to always
understand all C++11 keywords (which seems like the right thing to do).
llvm-svn: 187589
With this patch, clang-format can be configured to:
* not indent in namespace at all (former behavior).
* indent in namespace as in other blocks.
* indent only in inner namespaces (as required by WebKit style).
Also fix alignment of access specifiers in WebKit style.
Patch started by Marek Kurdej. Thank you!

On windows, c:foo is a valid file path, but stat fails on just "c:". This
causes a problem for clang since its file manager wants to cache data about
the parent directory.
There are refactorings to be done in here, but this gives clang the correct
behavior and testing first.

New options:
* Break before the commas of constructor initializers and align
the commas with the colon.
* Break before binary operators
Additionally, for styles without column limit, don't just accept
linebreaks done by the user, but instead remove 'invalid' (according
to the current style) linebreaks and add 'required' ones.

Summary:
Add support for Adaptative matchers on the dynamic registry.
Each adaptative matcher is created with a function template. We instantiate the function N times, one for each possible From type and apply the techniques used on argument overloaded and polymorphic matchers to add them to the registry.

This is far from implementing all the rules given by
http://www.webkit.org/coding/coding-style.html
The important new feature is the support for styles that don't have a
column limit. For such styles, clang-format will (at the moment) simply
respect the input's formatting decisions within statements.

Summary:
Add support for overloaded matchers.
This composes with other features, like supporting polymorphic matchers.

Motivating example:
// column limit ------------------->
void ffffffffffff(int aaaaaa /* test */);
Formatting before the patch:
void ffffffffffff(int aaaaaa /* test
*/);
Formatting after the patch:
void
ffffffffffff(int aaaaaa /* test */);

Summary:
These can appear when comments contain command lines with quoted line
breaks. As the text (including escaped newlines and '//' from consecutive lines)
is a single line comment, we used to break it even when it didn't exceed column
limit. This is a temporary solution, in the future we may want to support this
case completely - at least adjust leading whitespace when changing indentation
of the first line.

The fundamental concept is:
Format as if the braced init list was a function call (with parentheses
replaced by braces). If there is no name/type before the opening brace
(e.g. if the braced list is nested), assume a zero-length identifier
just before the opening brace.
This behavior is gated on a new style flag, which for now replaces the
SpacesInBracedLists style flag. Activate this style flag for Google
style to reflect recent style guide changes.

Fix some uninstantiable code in ASTVector::insert. I've added a
cheap-and-dirty compile test for this, because I don't have the time to
figure out a nice way to get a real ASTContext to implement executable
tests - but we probably should have them for this ADT.

Before this patch, it did not cooperate with
Style::AlwaysBreakBeforeMultilineStrings. Thus, it would turn
aaaaaaaaaaaa(aaaaaaaaaaaaa, "aaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaa");
into:
aaaaaaaaaaaa(aaaaaaaaaaaaa, "aaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaa "
"aaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaa");
and only a second format step would lead to the desired (with that
option):
aaaaaaaaaaaa(aaaaaaaaaaaaa,
"aaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaa "
"aaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaa");
This could even lead to clang-format breaking the string at a different
character and thus leading to a completely different end result.
llvm-svn: 186154
clang-format used to treat array subscript expressions much like
function call (just replacing () with []). However, this is not really
appropriate especially for expressions with multiple subscripts.
Although it might seem counter-intuitive, the most consistent solution
seems to be to always (if necessary) break before a square bracket,
never after it. Also, multiple subscripts of the same expression should
be aligned if they are on subsequent lines.
Before:
aaaaaaaaaaaaaaaaaaaaaaaaa[aaaaaaaaaaaaaaaaaaaaaaaaa][
bbbbbbbbbbbbbbbbbbbbbbbbb] = c;
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa[
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa][
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb] = ccccccccccc;
After:
aaaaaaaaaaaaaaaaaaaaaaaaa[aaaaaaaaaaaaaaaaaaaaaaaaa]
[bbbbbbbbbbbbbbbbbbbbbbbbb] = c;
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
[aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa]
[bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb] = ccccccccccc;
