Ted Kremenek 26a6d498ee Implement clang_getDiagnosticCategoryText() to provide a way for a client of libclang to accurately
get the diagnostic category name from a serialized diagnostic when the version of libclang used
to read the diagnostic file is newer than the clang that emitted the diagnostic file.

CXCursor clang_Cursor_getArgument(CXCursor C, unsigned i);

Argyrios Kyrtzidis 9d7c0fef65 [code-complete] Introduce CodeCompletionTUInfo which will be used for caching
code-completion related strings specific to a translation unit (ASTContext and related data)

CodeCompletionAllocator does such limited caching, by caching the name assigned
to a DeclContext*, but that is not the appropriate place since that object has
a lifetime that can extend beyond that of an ASTContext.

Introduce CodeCompletionTUInfo which will be always tied to a translation unit
to do this kind of caching and move the caching of CodeCompletionAllocator into this
object, and propagate it to all the places where it will be needed.

The plan is to extend the caching where appropriate, using CodeCompletionTUInfo,
to avoid re-calculating code-completion strings.

Argyrios Kyrtzidis 210f29f44b [libclang] Introduce clang_Cursor_getObjCSelectorIndex() function.
After getting a cursor with clang_getCursor for a particular source location,

selector identifier in an objc method or message expression, and which selector index it is.

Argyrios Kyrtzidis 191a6a86ad [libclang] Introduce clang_Cursor_getSpellingNameRange().
It retrieves a source range for a piece that forms the cursors spelling name.
Most of the times there is only one range for the complete spelling but for
objc methods and objc message expressions, there are multiple pieces for each
selector identifier.

Argyrios Kyrtzidis ab468b0381 Add info to ObjCPropertyRefExpr to indicate whether the dot syntax property
reference is going to message the setter, the getter, or both.

Having this info on the ObjCPropertyRefExpr node makes it easier for AST
clients (like libclang) to reason about the meaning of the property reference.

[AST/Sema]
-Use 2 bits (with a PointerIntPair) in ObjCPropertyRefExpr to record the above info
-Have ObjCPropertyOpBuilder set the info appropriately.

[libclang]
-When there is an implicit property reference (property syntax using methods)
have clang_getCursorReferenced return a cursor for the method. If the property
reference is going to result in messaging both the getter and the setter choose
to return a cursor for the setter because it is less obvious from source inspection
that the setter is getting called.

The general idea has the seal of approval by John.

Argyrios Kyrtzidis bfb2425c71 [libclang] Enhance clang_getOverriddenCursors.
Basically the current design is:
-for an implementation method, show as overridden the interface method.
  This is not useful, and is inconsistent with the C++ side
-for an interface method, show as overridden the protocols methods (this is desirable)
  and the methods from the categories; methods from categories are not useful
  since they are considered the same method (same USR).
-If there is a protocol method or category method reported, it does not check the
  super class for overridden methods. This is really problematic since
  overridden methods from super class is what we want to give back.

Change clang_getOverriddenCursors to show as overridden any method in the class's
base class, its protocols, or its categories' protocols, that has the same
selector and is of the same kind (class or instance).
If no such method exists, the search continues to the class's superclass,
its protocols, and its categories, and so on. A method from an Objective-C
implementation is considered to override the same methods as its
corresponding method in the interface.

Richard Smith c67fdd4eb9 AST representation for user-defined literals, plus just enough of semantic
analysis to make the AST representation testable. They are represented by a
new UserDefinedLiteral AST node, which is a sugared CallExpr. All semantic
properties, including full CodeGen support, are achieved for free by this
representation.

UserDefinedLiterals can never be dependent, so no custom instantiation
behavior is required. They are mangled as if they were direct calls to the
underlying literal operator. This matches g++'s apparent behavior (but not its
actual mangling, which is broken for literal-operator-ids).

User-defined *string* literals are now fully-operational, but the semantic
analysis is quite hacky and needs more work. No other forms of user-defined
literal are created yet, but the AST support for them is present.

This patch committed after midnight because we had already hit the quota for
new kinds of literal yesterday.

Argyrios Kyrtzidis 4a280ff48f [PCH] Mark a PCH file with a flag to indicate if the serialized AST had
compiler errors or not.

-Control whether ASTReader should reject such a PCH by a boolean flag at ASTReader's creation time.
By default, such a PCH file will be rejected with an error when trying to load it.

[libclang] Allow clang_saveTranslationUnit to create a PCH file even if compiler errors
occurred.
-Have libclang API calls accept a PCH that had compiler errors.

The general idea is that we want libclang to stay functional even if a PCH had a compiler error.

Ted Kremenek f7639e1b4a Add new code migrator support for migrating existing Objective-C code to use
the new Objective-C NSArray/NSDictionary/NSNumber literal syntax.

This introduces a new library, libEdit, which provides a new way to support

that most of its functionality can be refactored into the existing libraries,
and thus this new library may shortly disappear.

that provides the behavior of the C++11 library trait
std::is_trivially_constructible<T, Args...>, which can't be

Since __is_trivially_constructible can have zero or more arguments, I

handling arbitrary arguments. The next step will be to migrate
UnaryTypeTrait and BinaryTypeTrait over to this new, more general
TypeTrait class.

Sebastian Redl 86fab844bb Make CXXNewExpr contain only a single initialier, and not hold the used constructor itself.
Holding the constructor directly makes no sense when list-initialized arrays come into play. The constructor is now held in a CXXConstructExpr, if construction is what is done. The new design can also distinguish properly between list-initialization and direct-initialization, as well as implicit default-initialization constructors and explicit value-initialization constructors. Finally, doing it this way removes redundance from the AST because CXXNewExpr doesn't try to handle both the allocation and the initialization responsibilities.

This breaks the static analysis of new expressions. I've filed PR12014 to track this.
