2009-01-09When we see a reference to a struct, class, or union like "struct X"Douglas Gregor
that is neither a definition nor a forward declaration and where X has not yet been declared as a tag, introduce a declaration into the appropriate scope (which is likely *not* to be the current scope). The rules for the placement of the declaration differ slightly in C and C++, so we implement both and test the various corner cases. This implementation isn't 100% correct due to some lingering issues with the function prototype scope (for a function parameter list) not being the same scope as the scope of the function definition. Testcase is FIXME'd; this probably isn't an important issue. Addresses <rdar://problem/6484805>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62014 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-09Replace DeclContext's vector of ScopedDecl pointers with a linked listDouglas Gregor
of ScopedDecls (using the new ScopedDecl::NextDeclInScope pointer). Performance-wise: - It's a net win in memory utilization, since DeclContext is now one pointer smaller than it used to be (std::vectors are typically 3 pointers; we now use 2 pointers) and - Parsing Cocoa.h with -fsyntax-only (with a Release-Asserts Clang) is about 1.9% faster than before, most likely because we no longer have the memory allocations and copying associated with the std::vector. I'll re-enable serialization of DeclContexts once I've sorted out the NextDeclarator/NextDeclInScope question. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62001 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-09Provide a new kind of iterator, the specific_decl_iterator, thatDouglas Gregor
filters the decls seen by decl_iterator with two criteria: the dynamic type of the declaration and a run-time predicate described by a member function. This simplifies EnumDecl, RecordDecl, and ObjCContainerDecl considerably. It has no measurable performance impact. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61994 91177308-0d34-0410-b5e6-96231b3b80d8

Add isa/cast/dyncast support for ObjCContainerDecl. Renamed classprop_iterator/begin/end to prop_iterator/begin/end (the class prefix was confusing). More simplifications to Sema::ActOnAtEnd()... Added/changed some FIXME's as a result of the above work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61988 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-09Addressed the issue in <rdar://problem/6479085>, where we failed toDouglas Gregor
rewrite @class declarations that showed up within linkage specifications because those @class declarations never made it any place where the rewriter could find them. Moved all of the ObjC*Decl nodes over to ScopedDecls, so that they can live in the appropriate top-level or transparent DeclContext near the top level, e.g., TranslationUnitDecl or LinkageSpecDecl. Objective-C declarations now show up in a traversal of the declarations in a DeclContext (they didn't before!). This way, the rewriter finds all Objective-C declarations within linkage specifications. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61966 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-08Unify the code for defining tags in C and C++, so that we alwaysDouglas Gregor
introduce a Scope for the body of a tag. This reduces the number of semantic differences between C and C++ structs and unions, and will help with other features (e.g., anonymous unions) in C. Some important points: - Fields are now in the "member" namespace (IDNS_Member), to keep them separate from tags and ordinary names in C. See the new test in Sema/member-reference.c for an example of why this matters. In C++, ordinary and member name lookup will find members in both the ordinary and member namespace, so the difference between IDNS_Member and IDNS_Ordinary is erased by Sema::LookupDecl (but only in C++!). - We always introduce a Scope and push a DeclContext when we're defining a tag, in both C and C++. Previously, we had different actions and different Scope/CurContext behavior for enums, C structs/unions, and C++ structs/unions/classes. Now, it's one pair of actions. (Yay!) There's still some fuzziness in the handling of struct/union/enum definitions within other struct/union/enum definitions in C. We'll need to do some more cleanup to eliminate some reliance on CurContext before we can solve this issue for real. What we want is for something like this: struct X { struct T { int x; } t; }; to introduce T into translation unit scope (placing it at the appropriate point in the IdentifierResolver chain, too), but it should still have struct X as its lexical declaration context. PushOnScopeChains isn't smart enough to do that yet, though, so there's a FIXME test in nested-redef.c git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61940 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-08This is a large/messy diff that unifies the ObjC AST's with DeclContext.Steve Naroff
- ObjCContainerDecl's (ObjCInterfaceDecl/ObjCCategoryDecl/ObjCProtocolDecl), ObjCCategoryImpl, & ObjCImplementation are all DeclContexts. - ObjCMethodDecl is now a ScopedDecl (so it can play nicely with DeclContext). - ObjCContainerDecl now does iteration/lookup using DeclContext infrastructure (no more linear search:-) - Removed ASTContext argument to DeclContext::lookup(). It wasn't being used and complicated it's use from an ObjC AST perspective. - Added Sema::ProcessPropertyDecl() and removed Sema::diagnosePropertySetterGetterMismatch(). - Simplified Sema::ActOnAtEnd() considerably. Still more work to do. - Fixed an incorrect casting assumption in Sema::getCurFunctionOrMethodDecl(), now that ObjCMethodDecl is a ScopedDecl. - Removed addPropertyMethods from ObjCInterfaceDecl/ObjCCategoryDecl/ObjCProtocolDecl. This passes all the tests on my machine. Since many of the changes are central to the way ObjC finds it's methods, I expect some fallout (and there are still a handful of FIXME's). Nevertheless, this should be a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61929 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-06Add QualifiedDeclRefExpr, which retains additional source-locationDouglas Gregor
information for declarations that were referenced via a qualified-id, e.g., N::C::value. We keep track of the location of the start of the nested-name-specifier. Note that the difference between QualifiedDeclRefExpr and DeclRefExpr does have an effect on the semantics of function calls in two ways: 1) The use of a qualified-id instead of an unqualified-id suppresses argument-dependent lookup 2) If the name refers to a virtual function, the qualified-id version will call the function determined statically while the unqualified-id version will call the function determined dynamically (by looking up the appropriate function in the vtable). Neither of these features is implemented yet, but we do print out qualified names for QualifiedDeclRefExprs as part of the AST printing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61789 91177308-0d34-0410-b5e6-96231b3b80d8

Fully implement the low-hanging fruit of the type traits: __is_pod: Whether a type is a POD. __is_class: Whether a type is a (non-union) class. __is_union: Whether a type is a union. __is_enum: Whether a type is an enum. __is_polymorphic: Whether a type is polymorphic (C++ [class.virtual]p1). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61746 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-05Introduce support for "transparent" DeclContexts, which areDouglas Gregor
DeclContexts whose members are visible from enclosing DeclContexts up to (and including) the innermost enclosing non-transparent DeclContexts. Transparent DeclContexts unify the mechanism to be used for various language features, including C enumerations, anonymous unions, C++0x inline namespaces, and C++ linkage specifications. Please refer to the documentation in the Clang internals manual for more information. Only enumerations and linkage specifications currently use transparent DeclContexts. Still to do: use transparent DeclContexts to implement anonymous unions and GCC's anonymous structs extension, and, later, the C++0x features. We also need to tighten up the DeclContext/ScopedDecl link to ensure that every ScopedDecl is in a single DeclContext, which will ensure that we can then enforce ownership and reduce the memory footprint of DeclContext. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61735 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-24Correct the order in which we cope with end-of-class-definitionDouglas Gregor
semantics and improve our handling of default arguments. Specifically, we follow this order: - As soon as the see the '}' in the class definition, the class is complete and we add any implicit declarations (default constructor, copy constructor, etc.) to the class. - If there are any default function arguments, parse them - If there were any inline member function definitions, parse them As part of this change, we now keep track of the the fact that we've seen unparsed default function arguments within the AST. See the new ParmVarDecl::hasUnparsedDefaultArg member. This allows us to properly cope with calls inside default function arguments to other functions where we're making use of the default arguments.
