1) Supported by Clang, and
2) Supported by GCC, and
3) Documented in GCC's manual.
g++ allows its C++11-style attributes to appertain only to the entity being

clang-format should not change whether or not there is a line break

In ArrayRef<T>(X), X should not be temporary value. It could be rewritten more redundantly;
llvm::Type *XTy = X->getType();
ArrayRef<llvm::Type *> Ty(XTy);
llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, Ty);
Since it is safe if both XTy and Ty are temporary value in one statement, it could be shorten;
llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, ArrayRef<llvm::Type*>(X->getType()));
ArrayRef<T> has an implicit constructor to create uni-entry of T;
llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, X->getType());

canBreakBefore() does not allow breaking after ':' for LT_ObjCMethodDecl lines,

The testcase in pr14929 shows that this is extremely hard to do. If we choose
to apply the attribute, that causes the visibility of some decls to change and
that can happen really late (during codegen).
Current gcc warns and ignores the attribute in this testcase with a warning.
This suggest that the correct solution is to find a point in the compilation
where we can compute the visibility and
* assert it was never computed before
* reject any attempts to compute it again in the future (with warnings).

This follows the approach suggested by djasper in PR14911: When a '[' is
seen that's at the start of a line, follows a binary operator, or follows one
of : [ ( return throw, that '[' and its closing ']' are marked as
TT_ObjCMethodExpr and every ':' in that range that isn't part of a ternary
?: is marked as TT_ObjCMethodExpr as well.
Update the layout routines to not output spaces around ':' tokens that are
marked TT_ObjCMethodExpr, and only allow breaking after such tokens, not
before.

which a particular declaration resides. Use this information to
customize the "definition of 'blah' must be imported from another

Still TODO: coming up with decent Fix-Its for these cases, and expand

Previously, -Wunused-comparison ignored comparisons in both macro bodies and

RefactoringTool::run() always writes the result of rewrites to disk.
Instead, make this optional and provide a method for getting the
refactoring results in a memory buffer instead.
Also made ClangTool polymorphic so RefactoringTool could inherit from it
to properly express the IS-A relationship. This change also provides
access to ClangTool's public interface, e.g. mapVirtualFile() which is
important once refactored buffers start living in memory instead of on
disk.

It's better to show no caret/ranges/fixits than to show them misaligned.

To ensure that custom assertions/conditional would also be supported,

Objective-C method declarations look like this:
- (returntype)name:(type)argname anothername:(type)arg2name;
In google style, there's no space after the leading '-' but one after
"(returntype)" instead (but none after the argument types), see
http://google-styleguide.googlecode.com/svn/trunk/objcguide.xml#Method_Declarations_and_Definitions
Not inserting the space after '-' is easy, but to insert the space after the
return type, the formatter needs to know that a closing parenthesis ends the
return type. To do this, I tweaked the code in parse() to check for this, which
in turn required moving detection of TT_ObjCMethodSpecifier from annotate() to
parse(), because parse() runs before annotate().
(To keep things interesting, the return type is optional, but it's almost
always there in practice.)

In some cases, we just pick any ivar that needs invalidation and attach

Restructured the checker so that it could easily find two new classes of
issues:
- when a class contains an invalidatable ivar, but no declaration of an
invalidation method
- when a class contains an invalidatable ivar, but no definition of an
invalidation method in the @implementation.
The second case might trigger some false positives, for example, when
the method is defined in a category.

Don't do this in Google style though:
http://google-styleguide.googlecode.com/svn/trunk/objcguide.xml#Protocols
Most other places (function declarations, variable declarations) still get
this wrong, and since this looks very similiar to template instantiations to
the lexer (`id <MyProtocol> a = ...`), it's going to be hard to fix in some
places.

This will be a new style requirement going forwards: a diagnostic can only
use the implicit InGroup<DiagGroup<"foo">> syntax if "foo" is not used by
any other diagnostics; as soon as it is, it needs an explicit group.
This also brings some stray "conversion" diagnostics into the
"Value Conversion Issue" category, instead of the more generic
"Semantic Issue" category. I consider this an improvement!

Not only is this inefficient for TableGen, it's annoying for maintenance
when renaming warning flags (unusual) or adding those flags to a group
(more likely).
This uses the new fix-it infrastructure for LLVM's SourceMgr/SMDiagnostic,
as well as a few changes to TableGen to track more source information.
llvm-svn: 172087
This prepares the code for single line optimizations and changes the
dependencies between single-line-formats to the indent of the first
token.
Conceptually, the first token is "between" the lines anyway, as the
whitespace for the first token includes the previous end-of-line, which
needs to be escaped when inside a preprocessor directive.
llvm-svn: 172083
We now decide whether a newline should go before the closing brace
depending on whether a newline was inserted after the opening brace.
For example, we now insert a newline before '};' in:
static SomeClass WithALoooooooooooooooooooongName = {
100000000, \"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\"
};
... while not inserting a newline here:
static SomeClass = { a, b, c, d, e, f, g, h, i, j,
looooooooooooooooooooooooooooooooooongname,
looooooooooooooooooooooooooooooong };
Also fixes the formating of (column limit 25):
int x = {
avariable,
b(alongervariable)
};
llvm-svn: 172076
We're now formatting (column limit 25):
int x = {
avariable,
b(alongervariable) };
This also fixes:
Aaa({
int i;
}, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb,
ccccccccccccccccc));
... where we would previously break after the '},'.
Putting the closing curly into an extra line when there's a break
directly after the first curly will be done in a subsequent patch.
Paired with djasper.

Before: int (^myBlock) (int) = ^(int num) {}

For function types and function pointer types, this patch only makes
the behavior consistent (for types that are keywords and other types).
For the latter function pointer type declarations, we'll probably
want to add a space after "int".
Also added LangOpts.Bool = 1, so we handle "A<bool()>" appropriately
Moved the LangOpts-settings to a public place for use by tests
and clang-format binary.
llvm-svn: 172065
Previously, we would not indent:
SOME_MACRO({
int i;
});
correctly. This is fixed by adding the trailing }); to the unwrapped
line starting with SOME_MACRO({, so the formatter can correctly match
the braces and indent accordingly.
Also fixes incorrect parsing of initializer lists, like:
int a[] = { 1 };

Previously, we'd always start at indent level 0 after a preprocessor

follows:
functionCallTo(someOtherFunction(

areLongerThanALine(andAnotherCall,
B
withMoreParamters,
whichStronglyInfluenceTheLayout),

Note that the different jumping indent is a different issue that will be
addressed separately.
This is the first step towards handling #ifdef->#else->#endif chains
correctly.

This fixes llvm.org/PR14870 and we no longer mess up:
template <typename T1, typename T2 = char, typename T3 = char,

It removes the nice aligment for assignments inside other expressions,
but I am not sure those are actually practically relevant. If so, we can
fix those later.
llvm-svn: 171966
This addresses llvm.org/PR14847.
We can now format something like:
int aaaaaaaaaaaaaaaaaaaaaaaaaaa =

clang-format unavoidably exceeds the column limit, but does not just
flush everything into a single line. Moreover, it tries to minimize the
number of characters beyond the column limit.
llvm-svn: 171964
This fixes llvm.org/PR14860.

In the source
static void f();
static void f();
template<typename T>
static void g() {

the call to f refers to the second decl, but it is only marked used at the end
of the translation unit during instantiation, after the third f decl has been
linked in.
With this patch we mark all subsequent decls used, so that it is easy to check
if a symbol is used or not.

This is because we can't set "FirstInDeclGroup" consistently; for example, when visiting a DeclStmt we will set

This is a first step towards supporting more complex structures such

The issue here is that if we have 2 leaks reported at the same line for
which we cannot print the corresponding region info, they will get
treated as the same by issue_hash+description. We need to AUGMENT the
issue_hash with the allocation info to differentiate the two issues.
Add the "hash" (offset from the beginning of a function) representing
allocation site to solve the issue.
We might want to generalize solution in the future when we decide to
track more than just the 2 locations from the diagnostics.

This is in preparation for using this to construct the function type for

this was ever a macro name and return a specific CXCursor_MacroExpansion cursor in such a case,
instead of the generic CXCursor_MacroDefinition.
Checking for macro name makes sure the identifier is not part of the identifier list in a

While, in general, resolving identifiers in macro definitions to other macros may not be completely accurate,
it greatly improves functionality such as give-me-the-definition-of-this, which was not working at all
inside macro definitions.
