floating point comparisons using == or != an opt-in rather than a default
warning.

Updated test case to use -Wfloat-equal.

- Minor cleanup to yesterday's changes to Sema::ObjcActOnStartOfMethodDef();
- Add Sema::CurMethodDecl, in preparation for adding ObjcIvarRefExpr.
- Add ObjcInterfaceDecl::lookupInstanceVariable(), in prep for adding ivars.
- A couple renames in ObjcInterfaceDecl, while I was in the vicinity:-)

llvm-svn: 44015

This is the last 5% of the solution to teaching Sema::ActOnInstanceMessage() about private methods (r43989).

While the diff is large, the idea is very simple. When we parse method definitions (in an @implementation), we need to add them incrementally (rather than wait until the @end).

Other details...

- Renamed Sema::ActOnAddMethodsToObjcDecl() to Sema::ActOnAtEnd(). The methods are now optional arguments.
- Removed Parser::AllImplMethods (a nice cleanup).
- Added location info to ObjcImplementationDecl (since we will need it very soon:-)
- Modified message.m test to no longer allow the bogus diagnostic.

(1) serialize out top-level decls BEFORE serializing out translation unit
structures like ASTContext.

(2) deserialize out translation unit structures like ASTContext before
top-level decls by first skipping the decls in the bitstream, deserializing
ASTContext and friends, and then jumping back to the bitstream block with the
decls and then deserializing them.

Change (1) allows us to utilize the pointer-tracking system in the Serializer
to only serialize out metadata that is actually referenced by the ASTS.

Change (2) allows us to deserialize the metadata first as before, which
signficantly reduces the amount of pointer backpatching the deserializer
would have to do if the decls were deserialized first.

Rewrite global variable initializers. 

llvm-svn: 43947

- add typedef guards.
- tweak scanForProtocolRefs heuristic.
- disable RewriteInclude() for now.

llvm-svn: 43942

Rewrite RewriteObjCStringLiteral(). This version is simpler (and unlike the previous one, works:-)

llvm-svn: 43890

llvm-svn: 43882

Disable rewrite-tabs.  This speeds up processing of the commentified huge
crazy testcase steve gave me from 20s to 6.6s in a release build.

llvm-svn: 43880

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.

llvm-svn: 43831

llvm-svn: 43830

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

llvm-svn: 43790

file had the correct preamble.

llvm-svn: 43785

llvm-svn: 43778

Revampled Serialization Tester to serialize and deserialize out an entire ASTContext and top-level decls.

llvm-svn: 43773

llvm-svn: 43738

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!).
