2009-07-27Make ObjCImplDecl inherit from ObjCContainerDecl.Argyrios Kyrtzidis
ObjCContainerDecl now is the root class for objc decls that contain methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77235 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23Remove a bunch of FIXME's related to ObjC type checking.Steve Naroff
- Move Sema::ObjCQualifiedIdTypesAreCompatible(), Sema::QualifiedIdConformsQualifiedId(), and a couple helper functions to ASTContext. - Change ASTContext::canAssignObjCInterfaces() to use ASTContext:: ObjCQualifiedIdTypesAreCompatible(). - Tweak several test cases to accommodate the new/improved type checking. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76830 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-21- Introduce ASTContext::getObjCImplementation() and ↵Argyrios Kyrtzidis
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76508 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Remove ASTContext::isObjCObjectPointerType().Steve Naroff

2009-07-10This patch includes a conceptually simple, but very intrusive/pervasive change. Steve Naroff
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches. This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic. By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75314 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-30De-ASTContext-ify DeclContext.Argyrios Kyrtzidis
Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating". Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74506 91177308-0d34-0410-b5e6-96231b3b80d8

and objects of this class are derived from 'NSProxy'. Under such conditions, which means that every method possible is implemented in the class, we should not issue "Method definition not found" warnings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72267 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-04Remove support for ObjCMethodDecl attributes that appear between theTed Kremenek
return type and the selector. This is inconsistent with C functions (where such attributes would be placed on the return type, not the the FunctionDecl), and is inconsistent with what people are use to seeing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70878 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-30Hook up Sema support for attributes on Objective-C method declarations thatTed Kremenek
appear between the return type and the selector. This is a separate code path from regular attribute processing, as we only want to (a) accept only a specific set of attributes in this place and (b) want to distinguish to clients the context in which an attribute was added to an ObjCMethodDecl. Currently, the attribute 'objc_ownership_returns' is the only attribute that uses this new feature. Shortly I will add a warning for 'objc_ownership_returns' to be placed at the end of a method declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70504 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-24PCH support for the global method pool (= instance and factory methodDouglas Gregor
pools, combined). The methods in the global method pool are lazily loaded from an on-disk hash table when Sema looks into its version of the hash tables. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69989 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-24Eliminate Sema::ObjCImplementations, relying instead on name lookup. What's ↵Douglas Gregor
good for uniformity is good for PCH (or is it the other way around?). As part of this, make ObjCImplDecl inherit from NamedDecl (since ObjCImplementationDecls now need to have names so that they can be found). This brings ObjCImplDecl very, very close to ObjCContainerDecl; we may be able to merge them soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69941 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Eliminate Sema::ObjCProtocols. Instead, we place ObjCProtocolDecls inDouglas Gregor
their own namespace (IDNS_Protocol) and use the normal name-lookup routines to find them. Aside from the simplification this provides (one less DenseMap!), it means that protocols will be lazily deserialized from PCH files. Make the code size of the selector table block match the code size of the type and decl blocks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69939 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-23Sema::ActOnStartClassInterface(): Use PushOnScopeChains().Steve Naroff
This enables class recognition to work with PCH. I believe this means we can remove Sema::ObjCInterfaceDecls and it's usage within Sema::LookupName(). Will investigate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69891 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Eliminate the three SmallVectors in ObjCImplDecl (for instanceDouglas Gregor
methods, class methods, and property implementations) and instead place all of these entities into the DeclContext. This eliminates more linear walks when looking for class or instance methods and should make PCH (de-)serialization of ObjCDecls trivial (and lazy). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69849 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-14Audit __private_extern__ handling.Daniel Dunbar
- 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69020 91177308-0d34-0410-b5e6-96231b3b80d8
