assertions.
To ensure that custom assertions/conditional would also be supported,
just check if the ivar that needs to be invalidated or set to nil is
compared against 0.
Unfortunately, this will not work for code containing 'assert(IvarName)'

storage and thus is implicitly zero-initialized, no need to
do C++11 memory model. This patch unconditionally detects
such condition and zeroinitializer's the variable.
Patch has been commented on and OKed by Doug off-line.

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
the warning to it. Picking the first from DenseMap of pointer keys was
triggering non-deterministic output.

Truncation happens regularly when find_first_not_of returns npos,
strings long enough to trigger bug here are implausible.
No functionality change intended (ignoring absurd string lengths).

Before:
@property(assign, getter = isEditable) BOOL editable;
Now:
@property(assign, getter=isEditable) BOOL editable;
It'd be nice if some Apple person could let me know if spaces are preferred
around '=' in @synthesize lines (see FIXME in the test).
llvm-svn: 172110
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.

The first token in @implementation, @interface, and @protocol lines is now
marked TT_ObjCDecl, and lines starting with a TT_ObjCDecl token are now marked
LT_ObjCMethodDecl.
llvm-svn: 172093
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) {}
A<void ()>;
int (*b)(int);
After: int (^myBlock)(int) = ^(int num) {}
A<void()>;
int(*b)(int);
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 };
llvm-svn: 172058
This fixes llvm.org/PR14684.
Before: int *pa = (int *) & a;
After: int *pa = (int *)&a;
We still don't understand all kinds of casts. I added a FIXME to
address that.

difference between type widths of a vector and the width of one of its elements

Just reuse the @interface code for this. It accepts slightly more than
necessary (@implementation cannot have protocol lists), but that's ok.

Previously:
@interface Foo + (id)init; @end
Now:
@interface Foo
+ (id)init;
@end
Some tweaking remains, but this is a good first step.

Previously, we'd always start at indent level 0 after a preprocessor
directive, now we layout the following snippet (column limit 69) as
follows:
functionCallTo(someOtherFunction(
withSomeParameters, whichInSequence,
areLongerThanALine(andAnotherCall,
B
withMoreParamters,
whichStronglyInfluenceTheLayout),
andMoreParameters),
trailing);
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.
