Finishing touches on code generation for @try and friends.

- declare functions we use.
- cast arguments to objc_exception_match().
- don't take the & of _stack.buf.

Implement rewrite for @throw.

llvm-svn: 43820

Rewrite ObjC @try/@catch/@finally. Some minor tweaks to the AST nodes...

Still need to rewrite @throw (and do more testing)...

llvm-svn: 43803

llvm-svn: 43791

2) Fixed a regression in meta-data generation caused by removal of '_interface' prefix from synthesize class name.
3) Added stubs for @try/@catch/@finally statements.

llvm-svn: 43716

Declare objc_selector outside the prototype for objc_msgSend(), removing a silly warning.

llvm-svn: 43706

Rewrite @selector(sel).

llvm-svn: 43705

- change the synthesized typedef (for classes) to be of type "objc_object".
- fix a couple bugs in RewriteObjCStringLiteral.
- convert "Class" -> "id" in RewriteMessageExpr.

llvm-svn: 43704

Remove HandleObjcMetaDataEmission(), I inadvertantly resurrected it.

llvm-svn: 43690

Two additions...

- Synthesize the funky cast for objc_msgSend(). For the basic case, it looks like...

((id (*)(id, SEL))(void *)objc_msgSend)(obj, sel);

The "void *" cast is needed to workaround a GCC "bandaid" (Chris says it has something to do with the inliner). Without the extra "void *" cast, we get spurious warnings/notes that look like...

xx.m:17: warning: function called through a non-compatible type
xx.m:17: note: if this code is reached, the program will abort

- Add prototypes for the ObjC functions we call, objc_msgSend/objc_getClass for now (don't depend on them being included).

llvm-svn: 43685

Implement rewrite rules for ObjC string constants.

llvm-svn: 43665

ASTConsumer to process the AST before it is destroyed.
This allows elimination of HandleObjcMetaDataEmission.

llvm-svn: 43659

- Remove _interface_ prefix for the synthesized tag names.
- Also removed a tab from the generated struct (minor).

llvm-svn: 43616

Implement rewrite rule for commenting out protocol references. For example:

extern id /*<NSObject>*/ NSAllocateObject(Class aClass, unsigned extraBytes, NSZone *zone);

extern void NSDeallocateObject(id /*<NSObject>*/object);

extern id /*<NSObject>*/ NSCopyObject(id /*<NSObject>*/object, unsigned extraBytes, NSZone *zone);

llvm-svn: 43612

Tweak RewriteInterfaceDecl() to generate a typedef (if one hasn't already been generated).

llvm-svn: 43600

2) Fixed a test failure (which should have failed all along!).

llvm-svn: 43589

llvm-svn: 43586

llvm-svn: 43585

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;
};
{}

llvm-svn: 43582

llvm-svn: 43560

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...

llvm-svn: 43493

llvm-svn: 43481

llvm-svn: 43454

llvm-svn: 43439

llvm-svn: 43409

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.

llvm-svn: 43316

llvm-svn: 43313

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