Zaffanella, with tweaks from Abramo Bagnara.

llvm-svn: 76576

Use ObjCInterfaceDecl::getCategoryClassMethod() and ObjCInterfaceDecl::getCategoryInstanceMethod() for the same functionality.

llvm-svn: 76510

Remove Sema::LookupObjCImplementation and replace it with just calling ObjCInterfaceDecl::getImplementation().

llvm-svn: 76509

- Introduce ASTContext::getObjCImplementation() and ASTContext::setObjCImplementation() which use a DenseMap to associate
  an interface/category with its implementation (if one exists).

- Introduce ObjCInterfaceDecl::get/setImplementation() and ObjCCategoryDecl::get/setImplementation() that use the above methods.

- Add a compiler error for when a category is reimplemented.

don't replace the type of the field with 'int', from Enea Zaffanella!

llvm-svn: 76454

incomplete type (with a warning), from Enea Zaffanella!

llvm-svn: 76451

- Remove Sema::CheckPointeeTypesForAssignment(), a temporary API I added to ease migration to ObjCObjectPointerType. Convert Sema::CheckAssignmentConstraints() to no longer depend on the temporary API.
- Sema::ConvertDeclSpecToType(): Replace a couple FIXME's with an important comment/example.
- Sema::GetTypeForDeclarator(): Get the protocol's from the interface, NOT the declspec (to support the following C typedef idiom: "typedef C<P> T; T *obj").
- Sema::ObjCQualifiedIdTypesAreCompatible(): Removed some dead code.
- ASTContext::getObjCEncodingForTypeImpl(): Some minor cleanups.

until Doug Gregor's Type smart pointer code lands (or more discussion occurs).
These methods just call the new Type::getAs<XXX> methods, so we still have
reduced implementation redundancy. Having explicit getAsXXXType() methods makes
it easier to set breakpoints in the debugger.

llvm-svn: 76193

Replaced Type::getAsLValueReferenceType(), Type::getAsRValueReferenceType(), Type::getAsMemberPointerType(), Type::getAsTagType(), and Type::getAsRecordType() with their Type::getAs<XXX> equivalents.

This method is intended to eventually replace the individual
Type::getAsXXXType<> methods.

The motivation behind this change is twofold:

1) Reduce redundant implementations of Type::getAsXXXType() methods. Most of
them are basically copy-and-paste.

2) By centralizing the implementation of the getAs<Type> logic we can more
smoothly move over to Doug Gregor's proposed canonical type smart pointer
scheme.

Along with this patch:

a) Removed 'Type::getAsPointerType()'; now clients use getAs<PointerType>.
b) Removed 'Type::getAsBlockPointerTypE()'; now clients use getAs<BlockPointerType>.

llvm-svn: 76098

nonfragile abi, instead of crashing.

llvm-svn: 76088

Convert all clients to use the new predicate on Type.

Patch by Ryan Flynn

This is fallout from the recent ObjCObjectPointerType rework. I'll work on fixing this tomorrow.

llvm-svn: 75870

Objective-C pointers to using ObjCObjectPointerType.

Now the checking for 'attribute ((nonnull))' in Sema doesn't emit an error when
trying to apply that attribute to a parameter that is an Objective-C pointer
(this is a regression).

To prevent this regression from occuring in the future, the 'nonnull.c' test was
moved to test/SemaObjC and renamed 'nonnull.m'. I also enhanced the tests to
show that function calls involved a NULL Objective-C pointer constant does not
trigger a warning. This is consistent with GCC, but should likely be fixed.

llvm-svn: 75856

base/members.

llvm-svn: 75849

llvm-svn: 75832

Implement the ObjC pseudo built-in types as clang "BuiltinType's". I say pseudo built-in types, since Sema still injects a typedef for recognition (i.e. they aren't truly built-ins from a parser perspective).

This removes the static data/methods on ObjCObjectPointerType while preserving the nice API (no need to fiddle with ASTContext:-).

This patch also adds Type::isObjCBuiltinType().

This should be the last fairly large patch related to recrafting the ObjC type system. The follow-on patches should be fairly small.

I don't love the name, however it simplifies the code and is a worthwhile change. If/when we come up with a better name, we can do a search/replace.

semantics of order of construction [class.init].

Note: One day, it might be useful to consider adding this info to DeclGroup (as the comments in FunctionDecl/VarDecl suggest). For now, I think this works fine. I considered moving this to ValueDecl (a common ancestor of FunctionDecl/VarDecl/FieldDecl), however this would add overhead to EnumConstantDecl (which would burn memory and isn't necessary).

For C++ overloaded operator calls, set the source location of the DeclRefExpr to the location of the operator.

- Declaration context of ParmVarDecls (that we got from the Declarator) was not their containing function.
- C++ out-of-line method definitions didn't get an access specifier.

Both were exposed by a crash when emitting a C++ method to a PCH file (assert at Decl::CheckAccessDeclContext()).

- Remove a couple redundant casts/returns.
- Fix 80 column violations for all getAsStringInternal() methods.

llvm-svn: 75485

Still more to come...just wanted to get the no-brainers out of the way.

llvm-svn: 75477

Implement more of C++0x 'auto'. A variable with an auto type specifier must have an initializer. Also, move some tests around to match the C++0x draft better.

llvm-svn: 75322

  warning: ‘OPT’ may be used uninitialized in this function

Now OPT is initialized to NULL. I'm not certain if this is the correct fix;
others please review.
