2009-01-06Allow Objective-C entities to be declared within a transparent contextDouglas Gregor
nested in the translation unit. This fixes <rdar://problem/6476070>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61832 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
2008-12-23Don't explicitly represent OverloadedFunctionDecls withinDouglas Gregor
DeclContext. Instead, just keep the list of currently-active declarations and only build the OverloadedFunctionDecl when we absolutely need it. This is a half-step toward eliminating the need to explicitly build OverloadedFunctionDecls that store sets of overloaded functions. This was suggested by Argiris a while back, and it's a good thing for several reasons: first, it eliminates the messy logic that currently tries to keep the OverloadedFunctionDecl in sync with the declarations that are being added. Second, it will (eventually) eliminate the need to allocate memory for overload sets, which could help performance. Finally, it helps set us up for when name lookup can return multiple (possibly ambiguous) results, as can happen with lookup of class members in C++. Next steps: make the IdentifierResolver store overloads as separate entries in its list rather than replacing them with an OverloadedFunctionDecl now, then see how far we can go toward eliminating OverloadedFunctionDecl entirely. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61357 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-11Unifies the name-lookup mechanisms used in various parts of the ASTDouglas Gregor
and separates lexical name lookup from qualified name lookup. In particular: * Make DeclContext the central data structure for storing and looking up declarations within existing declarations, e.g., members of structs/unions/classes, enumerators in C++0x enums, members of C++ namespaces, and (later) members of Objective-C interfaces/implementations. DeclContext uses a lazily-constructed data structure optimized for fast lookup (array for small contexts, hash table for larger contexts). * Implement C++ qualified name lookup in terms of lookup into DeclContext. * Implement C++ unqualified name lookup in terms of qualified+unqualified name lookup (since unqualified lookup is not purely lexical in C++!) * Limit the use of the chains of declarations stored in IdentifierInfo to those names declared lexically. * Eliminate CXXFieldDecl, collapsing its behavior into FieldDecl. (FieldDecl is now a ScopedDecl). * Make RecordDecl into a DeclContext and eliminates its Members/NumMembers fields (since one can just iterate through the DeclContext to get the fields). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60878 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-05Representation of template type parameters and non-type templateDouglas Gregor
parameters, with some semantic analysis: - Template parameters are introduced into template parameter scope - Complain about template parameter shadowing (except in Microsoft mode) Note that we leak template parameter declarations like crazy, a problem we'll remedy once we actually create proper declarations for templates. Next up: dependent types and value-dependent/type-dependent expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60597 91177308-0d34-0410-b5e6-96231b3b80d8

struct A { struct B; }; struct A::B { void m() {} // Assertion failed: getContainingDC(DC) == CurContext && "The next DeclContext should be lexically contained in the current one." }; Introduce DeclContext::getLexicalParent which may be different from DeclContext::getParent when nested-names are involved, e.g: namespace A { struct S; } struct A::S {}; // getParent() == namespace 'A' // getLexicalParent() == translation unit git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59650 91177308-0d34-0410-b5e6-96231b3b80d8

the other way around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59646 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-17Updated IdentifierResolver to deal with DeclarationNames. The names ofDouglas Gregor
C++ constructors, destructors, and conversion functions now have a FETokenInfo field that IdentifierResolver can access, so that these special names are handled just like ordinary identifiers. A few other Sema routines now use DeclarationNames instead of IdentifierInfo*'s. To validate this design, this code also implements parsing and semantic analysis for id-expressions that name conversion functions, e.g., return operator bool(); The new parser action ActOnConversionFunctionExpr takes the result of parsing "operator type-id" and turning it into an expression, using the IdentifierResolver with the DeclarationName of the conversion function. ActOnDeclarator pushes those conversion function names into scope so that the IdentifierResolver can find them, of course. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59462 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-17Introduction the DeclarationName class, as a single, general method ofDouglas Gregor
representing the names of declarations in the C family of languages. DeclarationName is used in NamedDecl to store the name of the declaration (naturally), and ObjCMethodDecl is now a NamedDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59441 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-07Parsing, ASTs, and semantic analysis for the declaration of conversionDouglas Gregor
functions in C++, e.g., struct X { operator bool() const; }; Note that these conversions don't actually do anything, since we don't yet have the ability to use them for implicit or explicit conversions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58860 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-05Parsing, representation, and preliminary semantic analysis of destructors.Douglas Gregor
Implicit declaration of destructors (when necessary). Extended Declarator to store information about parsed constructors and destructors; this will be extended to deal with declarators that name overloaded operators (e.g., "operator +") and user-defined conversion operators (e.g., "operator int"). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58767 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-31Add support for parsing and representing C++ constructor declarations.Douglas Gregor
Notes: - Constructors are never found by name lookup, so they'll never get pushed into any scope. Instead, they are stored as an OverloadedFunctionDecl in CXXRecordDecl for easy overloading. - There's a new action isCurrentClassName that determines whether an identifier is the name of the innermost class currently being defined; we use this to identify the declarator-id grammar rule that refers to a type-name. - MinimalAction does *not* support parsing constructors. - We now handle virtual and explicit function specifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58499 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-15Simplify handling of struct/union/class tags.Argyrios Kyrtzidis
Instead of using two sets of Decl kinds (Struct/Union/Class and CXXStruct/CXXUnion/CXXClass), use one 'Record' and one 'CXXRecord' Decl kind and make tag kind a property of TagDecl. Cleans up the code a bit and better reflects that Decl class structure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57541 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-12Implement more efficient Decl <-> DeclContext conversions.Argyrios Kyrtzidis
When the static type on the Decl side is a subclass of DeclContext the compiler will use a "inlinable" static_cast, instead of always using an out-of-line function call. Note, though, that the isa<> check still uses an out-of-line function call. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57415 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-20Try to plug some memory leaks...Ted Kremenek
1) Sema::ParseAST now constructs a TranslationUnit object to own the top-level Decls, which releases the top-level Decls upon exiting ParseAST. 2) Bug fix: TranslationUnit::~TranslationUnit handles the case where a Decl is added more than once as a top-level Decl. 3) Decl::Destroy is now a virtual method, obviating the need for a special dispatch based on DeclKind. 3) FunctionDecl::Destroy now releases its Body using its Destroy method. 4) Added Stmt::Destroy and Stmt::DestroyChildren, which recursively delete the child ASTs of a Stmt and call their dstors. We may need to special case dstor/Destroy methods for particular Stmt subclasses that own other dynamically allocated objects besides AST nodes. 5) REGRESSION: We temporarily are not deallocating attributes; a FIXME is provided. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51286 91177308-0d34-0410-b5e6-96231b3b80d8
