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

- Change definition of store::Region and store::Binding (once again) to make them real classes that just wrap pointers. This makes them more strictly typed, and allows specific implementations of Regions/Bindings to just subclass them. - minor renamings to RegionExtent and its subclasses - added a bunch of doxygen comments StoreManager: (static analyzer) - added 'iterBindings', an iteration method for iterating over the bindings of a store. It that takes a callback object (acting like a poor man's closure). - added 'getRVal' version for store::Binding. Will potentially phase the other versions of GetRVal in StoreManager out. - reimplemented 'getBindings' to be non-virtual and to use 'iterBindings' BasicStoreManager: (static analyzer) - implemented 'iterBindings' for BasicStoreManager git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55688 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
