2008-12-16Warning fixes to operator precedence warnings.Eli Friedman
Someone should double-check that I didn't somehow break ObjC serialization; I think the change there actually changes the semantics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61098 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-15Place constructors and destructors into the DeclContext of the class,Douglas Gregor
just like all other members, and remove the special variables in CXXRecordDecl to store them. This eliminates a lot of special-case code for constructors and destructors, including ActOnConstructor/ActOnDeclarator and special lookup rules in LookupDecl. The result is far more uniform and manageable. Diagnose the redeclaration of member functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61048 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

2008-11-17Eliminate all of the placeholder identifiers used for constructors,Douglas Gregor
destructors, and conversion functions. The placeholders were used to work around the fact that the parser and some of Sema really wanted declarators to have simple identifiers; now, the code that deals with declarators will use DeclarationNames. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59469 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
2008-11-12Don't build identifiers for C++ constructors, destructors, orDouglas Gregor
conversion functions. Instead, we just use a placeholder identifier for these (e.g., "<constructor>") and override NamedDecl::getName() to provide a human-readable name. This is one potential solution to the problem; another solution would be to replace the use of IdentifierInfo* in NamedDecl with a different class that deals with identifiers better. I'm also prototyping that to see how it compares, but this commit is better than what we had previously. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59193 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

2008-11-05Implement C++ copy-initialization for declarations. There is now someDouglas Gregor
duplication in the handling of copy-initialization by constructor, which occurs both for initialization of a declaration and for overloading. The initialization code is due for some refactoring. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58756 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-03Add implicitly-declared default and copy constructors to C++ classes,Douglas Gregor
when appropriate. Conversions for class types now make use of copy constructors. I've replaced the egregious hack allowing class-to-class conversions with a slightly less egregious hack calling these conversions standard conversions (for overloading reasons). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58622 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-31Implement basic support for converting constructors in user-defined Douglas Gregor
conversions. Notes: - Overload resolution for converting constructors need to prohibit user-defined conversions (hence, the test isn't -verify safe yet). - We still use hacks for conversions from a class type to itself. This will be the case until we start implicitly declaring the appropriate special member functions. (That's next on my list) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58513 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

2008-09-05Change struct forward declarations and definitions to use unique ↵Ted Kremenek
RecordDecls, as opposed to creating a single RecordDecl and reusing it. This change effects both RecordDecls and CXXRecordDecls, but does not effect EnumDecls (yet). The motivation of this patch is as follows: - Capture more source information, necessary for refactoring/rewriting clients. - Pave the way to resolve ownership issues with RecordDecls with the forthcoming addition of DeclGroups. Current caveats: - Until DeclGroups are in place, we will leak RecordDecls not explicitly referenced by the AST. For example: typedef struct { ... } x; The RecordDecl for the struct will be leaked because the TypedefDecl doesn't refer to it. This will be solved with DeclGroups. - This patch also (temporarily) breaks CodeGen. More below. High-level changes: - As before, TagType still refers to a TagDecl, but it doesn't own it. When a struct/union/class is first referenced, a RecordType and RecordDecl are created for it, and the RecordType refers to that RecordDecl. Later, if a new RecordDecl is created, the pointer to a RecordDecl in RecordType is updated to point to the RecordDecl that defines the struct/union/class. - TagDecl and RecordDecl now how a method 'getDefinition()' to return the TagDecl*/RecordDecl* that refers to the TagDecl* that defines a particular enum/struct/class/union. This is useful from going from a RecordDecl* that defines a forward declaration to the RecordDecl* that provides the actual definition. Note that this also works for EnumDecls, except that in this case there is no distinction between forward declarations and definitions (yet). - Clients should no longer assume that 'isDefinition()' returns true from a RecordDecl if the corresponding struct/union/class has been defined. isDefinition() only returns true if a particular RecordDecl is the defining Decl. Use 'getDefinition()' instead to determine if a struct has been defined. - The main changes to Sema happen in ActOnTag. To make the changes more incremental, I split off the processing of enums and structs et al into two code paths. Enums use the original code path (which is in ActOnTag) and structs use the ActOnTagStruct. Eventually the two code paths will be merged, but the idea was to preserve the original logic both for comparison and not to change the logic for both enums and structs all at once. - There is NO CHAINING of RecordDecls for the same RecordType. All RecordDecls that correspond to the same type simply have a pointer to that type. If we need to figure out what are all the RecordDecls for a given type we can build a backmap. - The diff in CXXRecordDecl.[cpp,h] is actually very small; it just mimics the changes to RecordDecl. For some reason 'svn' marks the entire file as changed. Why is CodeGen broken: - Codegen assumes that there is an equivalence between RecordDecl* and RecordType*. This was true before because we only created one RecordDecl* for a given RecordType*, but it is no longer true. I believe this shouldn't be too hard to change, but the patch was big enough as it is. I have tested this patch on both the clang test suite, and by running the static analyzer over Postgresql and a large Apple-internal project (mix of Objective-C and C). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55839 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-05Remove "NextDecl" from RecordDecl. This change touches many files that ↵Ted Kremenek
where RecordDecl or CXXRecordDecl was constructed, always with an argument of 'NULL' for the previous declaration. The motivation behind this change is that chaining the RecordDecls is simply unnecessary. Once we create multiple RecordDecls for the same struct/union/class, clients that care about all the declarations of the same struct can build a back map by seeing which Decls refer to the same RecordType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55821 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-02CXXRecordDecl and RecordDecl:Ted Kremenek
- Change constructor and create methods to accept a CXXRecordDecl* (RecordDecl*) instead of a ScopedDecl* for PrevDecl. This causes the type checking to be more tight and doesn't break any code. RecordDecl: - Don't use the NextDeclarator field in ScopedDecl to represent the previous declaration. This is a conflated use of the NextDeclarator field, which will be removed anyway when DeclGroups are fully implemented. - Instead, represent (a soon to be implemented) chain of RecordDecls using a NextDecl field. The last RecordDecl in the chain is always the 'defining' RecordDecl that owns the FieldDecls. The other RecordDecls in the chain are forward declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55640 91177308-0d34-0410-b5e6-96231b3b80d8
