2009-04-24Fix a pasto in the lookup of instance methods in the global poolDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69996 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::ObjCAliasDecls. This is based on Steve's fix, but alsoDouglas Gregor
updates name lookup so that we see through @compatibility_alias declarations to their underlying interfaces. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69950 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-24Eliminate Sema::ObjCInterfaceDeclsDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69942 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

@implementation that closes a @class delcaration. - I don't know how to make a test case for this, but this strengthens the invariants that hold internally.

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

2009-04-13Change diagnostic as a result of researching <rdar://problem/6779809> ↵Steve Naroff
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68967 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-12Fix rdar://6771034: don't warn on use of forward declared protocol in protocolChris Lattner
list of another protocol definition. This warning is very noisy and GCC doesn't produce it so existing code doesn't expect it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68894 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-11improve location info for property stuff. In a property like this:Chris Lattner
@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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68880 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-29Push DeclGroup much farther throughout the compiler. Now the variousChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68002 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-28Introduce a new OpaquePtr<N> struct type, which is a simple POD wrapper for aChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67952 91177308-0d34-0410-b5e6-96231b3b80d8
