Chris Lattner 9fecd743ca add a new Sema::CurFunctionNeedsScopeChecking bool that is used to avoid
calling into the jump checker when a function or method is known to contain
no VLAs or @try blocks.

Fariborz Jahanian 47b21081cb Patch to remove a bogus warning which pointed to underlying AST
gen. issue for property in continuation class declared readwrite 
but which did not generate the declaration for the setter. Fix also
removed a FIXME and resulted in code cleanup.

Daniel Dunbar 0ca1660129 Audit __private_extern__ handling.
- Exposed quite a few Sema issues and a CodeGen crash.

 - See FIXMEs in test case, and in SemaDecl.cpp (PR3983).

I'm skeptical that __private_extern__ should actually be a storage
class value. I think that __private_extern__ basically amounts to
  extern A __attribute__((visibility("hidden")))
and would be better off handled (a) as that, or (b) with an extra bit
in the VarDecl.

Steve Naroff 42959b2660 Change diagnostic as a result of researching <rdar://problem/6779809> missing interface name in "error: cannot declare variable inside a class, protocol or category ''.
Since ObjC 2.0 class "extensions" have a null name, the diagnostic above is actually "correct". Nevertheless, it is confusing. Decided to remove the name entirely (from my perspective, it didn't add any value). Also simplified the text of the diagnostic a bit.

Chris Lattner dac168d2a6 Fix rdar://6771034: don't warn on use of forward declared protocol in protocol
list of another protocol definition.  This warning is very noisy and GCC doesn't
produce it so existing code doesn't expect it.

Chris Lattner 5300accc7a improve location info for property stuff. In a property like this:
@property int x;

associate the location of X with the property decl, not the location
of the @.  Also, pass this info along to the synthesized ParmVarDecls
so that redefinition and other diagnostics can use it.  This eliminates
a fixme.

Chris Lattner 67f35b051b improve the 'conflicting types' diagnostics to include correct location info, now
that it is plumbed through Sema.  On a file from growl, we used to emit:

t.mi:107059:1: warning: conflicting types for 'removePluginHandler:forPluginTypes:'
- (void) removePluginHandler:(id <GrowlPluginHandler>)handler forPluginTypes:(NSSet *)extensions {
^
t.mi:105280:1: note: previous definition is here
- (void) removePluginHandler:(id <NSObject>)handler forPluginTypes:(NSSet *)types;
^

now we produce:

t.mi:107059:55: warning: conflicting parameter types in implementation of 'removePluginHandler:forPluginTypes:': 'id<NSObject>' vs 'id<GrowlPluginHandler>'
- (void) removePluginHandler:(id <GrowlPluginHandler>)handler forPluginTypes:(NSSet *)extensions {
                                                      ^
t.mi:105280:45: note: previous definition is here
- (void) removePluginHandler:(id <NSObject>)handler forPluginTypes:(NSSet *)types;
                                            ^

We still don't have proper loc info for properties, hence the FIXME.

Chris Lattner 5bbb3c8ad9 Push DeclGroup much farther throughout the compiler. Now the various
productions (except the already broken ObjC cases like @class X,Y;) in 
the parser that can produce more than one Decl return a DeclGroup instead
of a Decl, etc.

This allows elimination of the Decl::NextDeclarator field, and exposes
various clients that should look at all decls in a group, but which were
only looking at one (such as the dumper, printer, etc).  These have been
fixed.

Still TODO:

1) there are some FIXME's in the code about potentially using
DeclGroup for better location info.
2) ParseObjCAtDirectives should return a DeclGroup due to @class etc.
3) I'm not sure what is going on with StmtIterator.cpp, or if it can
   be radically simplified now.
4) I put a truly horrible hack in ParseTemplate.cpp.

I plan to bring up #3/4 on the mailing list, but don't plan to tackle
#1/2 in the short term.

Chris Lattner 83f095cc7e Introduce a new OpaquePtr<N> struct type, which is a simple POD wrapper for a
pointer.  Its purpose in life is to be a glorified void*, but which does not
implicitly convert to void* or other OpaquePtr's with a different UID.

Introduce Action::DeclPtrTy which is a typedef for OpaquePtr<0>.  Change the 
entire parser/sema interface to use DeclPtrTy instead of DeclTy*.  This
makes the C++ compiler enforce that these aren't convertible to other opaque
types.

We should also convert ExprTy, StmtTy, TypeTy, AttrTy, BaseTy, etc,
but I don't plan to do that in the short term.

The one outstanding known problem with this patch is that we lose the 
bitmangling optimization where ActionResult<DeclPtrTy> doesn't know how to
bitmangle the success bit into the low bit of DeclPtrTy.  I will rectify
this with a subsequent patch.

Ted Kremenek 9a46804ca8 Make Selector::getIdentifierInfo() private. I took a first attempt at this last
week in:

http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20090302/013580.html

That patch caused the output of the diagnostics to change. Since
'DeclarationName' can already reason about Selectors and the Diagnostics logic
reasons about DeclarationName, there is no additional code needed to get the
diagnostics working by making Selector::getIdentifierInfo() private.

Ted Kremenek 0666a6ce70 Selector: (changes made after discussing this more with Steve Naroff)
- Make Selector::getAsIdentifierInfo() private.  Using IdentifierInfo* in
  Selector is an implementation detail that clients shouldn't think about.
- Modify diagnostic emission in Sema::ProcessPropertyDecl to not use
  Selector::getAsIdentifierInfo() (which could crash when IdentifierInfo* is
  null) and instead use Selector::getAsString().
- Tidy up Selector::getAsString() implementation.

Chris Lattner 9ef10f4638 "This patch uses the new ObjCImplDecl class to merge Sema::ImplMethodsVsClassMethods and Sema::ImplCategoryMethodsVsIntfMethods methods.
And now, when clang check a class implementation to find unimplemented methods, it also checks all methods from the class extensions (unnamed categories).

There is also a test case to check this warning.

This patch contains also a minor update for ObjCImplDecl . getNameAsCString and getNameAsString now returns an empty string instead of crashing for unnamed categories."

Steve Naroff d123bd05ca Fix <rdar://problem/6451399> problems with labels and blocks.
- Move the 'LabelMap' from Sema to Scope. To avoid layering problems, the second element is now a 'StmtTy *', which makes the LabelMap a bit more verbose to deal with.
- Add 'ActiveScope' to Sema. Managed by ActOnStartOfFunctionDef(), ObjCActOnStartOfMethodDef(), ActOnBlockStmtExpr().
- Changed ActOnLabelStmt(), ActOnGotoStmt(), ActOnAddrLabel(), and ActOnFinishFunctionBody() to use the new ActiveScope.
- Added FIXME to workaround in ActOnFinishFunctionBody() (for dealing with C++ nested functions).
