Fix two rewriter bugs:

- For @class, don't generate multiple typedefs.
- Handle the following edge case interface...

@interface NSMiddleSpecifier : NSObject {}

@end

...which was incorrectly being rewritten to...

struct _interface_NSMiddleSpecifier {
        struct _interface_NSObject _NSObject;
};
{}

Checking in some code that is still under construction.

I need to (finally) change the way Class/id/SEL/IMP are built-in...the current approach of doing it in the preprocessor is "broken". The other problem is Sema::GetObjcIdType/GetObjcSelType/GetObjcClassType, the hooks that initialize ASTContext lazily. These built-in types need to be done up front...

llvm-svn: 43557

Add some plumbing to help cope with rewriting "id<p>", "Class<p>*".

llvm-svn: 43543

Stop pre-defining objc_msgSend/objc_getClass in the preprocessor. Instead, I generate these declaration on the fly when rewriting a message expression.

llvm-svn: 43529

Rewrite protocols.

llvm-svn: 43503

- Add location info to category/protocol AST's
- Rewrite categories.

llvm-svn: 43501

Remove a couple FIXME's for rewriting ObjC interfaces (which are now being rewritten properly).

llvm-svn: 43494

More support for rewriting ObjC intefaces. Still some edge cases to handle...

Start rewriting ObjC interfaces. As a start, we comment out all the methods. This involved refining how the parser/AST passes/manages SourceLocations for ObjcMethodDecl's. 

llvm-svn: 43404

Thanks to Steve N. to point out using of offsetof for this.

llvm-svn: 43391

Changed the entire rewrite of metadata to write to std::string
object instead of stdout.

llvm-svn: 43360

printf as an example.

llvm-svn: 43346

instance/class methods metadata.

llvm-svn: 43320

Still to do:

- Chris will fix a bug in the rewriting engine for nested stmts. For example, the following:

    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; 

tranlates to:

    NSAutoreleasePool * pool = objc_msgSend(objc_msgSend(objc_getClass("NSAutoreleasePool"), sel_getUid("alloc")), sel_getUid("init"))utoreleasePool"), sel_getUid("alloc")) init];

...which is correct, except there is garbage after sel_getUid("init"). This is because the rewriter isn't updating the extent of the containing message expression. 

- Do the crazy cast thang.

protocol meta-data (unlike what documentation says). 2) Include objc.h so,
we can compile the generated metadata with both gcc and clang.

llvm-svn: 43311

Implemented emission of category metadata,

llvm-svn: 43308

llvm-svn: 43299

This will make nested subexprs work.

llvm-svn: 43296

Incorporate some feedback from Chris...

llvm-svn: 43285

Add some plumbing to rewrite message expressions (still under construction).

llvm-svn: 43274

- Add rewrite rule for @class.
- Add setter/getter to ObjcClassDecl.
- Predefined key runtime functions.

we currently turn:

    c = @encode(char *)[2] + 4;

into:

    c = "foo"[2] + 4;

Right now the foo string is hard coded, but you can imagine a world
where it wouldn't be :)

llvm-svn: 43093

@selector probably gets this wrong also.

llvm-svn: 43048

Rename SourceRange::Begin()/End() to getBegin()/getEnd() for
consistency with other code.
Start building the rewriter towards handling @encode.

llvm-svn: 43047

#import to #include's as a test.

llvm-svn: 43041

$ clang rewrite.c -rewrite-test
prints:

int foo() {
        b:      foo();
f:      foo();
    foo();
}

for:

int foo() {
	b:	foo();
f:	foo();
    foo();
}

amazing.
