2010-09-08Fix C++ PCH issues.Argyrios Kyrtzidis
PCH got a severe beating by the boost-using test case reported here: http://llvm.org/PR8099 Fix issues like: -When PCH reading, make sure Decl's getASTContext() doesn't get called since a Decl in the parent hierarchy may be initializing. -In ASTDeclReader::VisitFunctionDecl VisitRedeclarable should be called before using FunctionDecl's isCanonicalDecl() -In ASTDeclReader::VisitRedeclarableTemplateDecl CommonOrPrev must be initialized before anything else. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113391 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-01Implement libclang support for using declarations. Clang actually usesDouglas Gregor
three different kinds of AST nodes to represent using declarations: UsingDecl, UnresolvedUsingValueDecl, and UnresolvedUsingTypenameDecl. These three are collapsed into a single cursor kind for using declarations, since libclang clients don't need the distinction. Several related changes here: - Cursor visitation of the three AST nodes for using declarations - Proper source-range computation for these AST nodes - Using declarations have no USRs, since they don't actually declare any entities. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112730 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-01Implement libclang support for using directives (cursor + visitation +Douglas Gregor
suppressing USRs). Also, fix up the source location information for using directives so that the declaration location refers to the namespace name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112693 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-01Split ObjCInterfaceDecl::ReferencedProtocols into two lists: ↵Ted Kremenek
ReferencedProtocols and AllReferencedProtocols. ReferencedProtocols (and thus protocol_begin(), protocol_end()) now only contains the list of protocols that were directly referenced in an @interface declaration. 'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced in both the @interface and class extensions. The latter is needed for semantic analysis/codegen, while the former is needed to maintain the lexical information of the original source. Fixes <rdar://problem/8380046>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112691 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-01Improve location information in the representation of namespaceDouglas Gregor
aliases. Previously, the location of the alias was at the "namespace" keyword. Now, it's on the identifier being declared (as is the custom for Clang), and we keep a separate source location for the "namespace" keyword. Also, added a getSourceRange() member function to NamespaceAliasDecl to correctly compute the source range. Finally, removed a bunch of setters from NamespaceAliasDecl and gave ASTReaderDecl friendship so that it could set the corresponding fields directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112681 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-28Fix the memory leak of FloatingLiteral/IntegerLiteral.Argyrios Kyrtzidis
For large floats/integers, APFloat/APInt will allocate memory from the heap to represent these numbers. Unfortunately, when we use a BumpPtrAllocator to allocate IntegerLiteral/FloatingLiteral nodes the memory associated with the APFloat/APInt values will never get freed. I introduce the class 'APNumericStorage' which uses ASTContext's allocator for memory allocation and is used internally by FloatingLiteral/IntegerLiteral.

2010-08-20Fix an issue with writing to PCH another included PCH, introduced by the ↵Argyrios Kyrtzidis
"using an AST on-disk hash table for name lookup" commit. When including a PCH and later re-emitting to another PCH, the name lookup tables of DeclContexts may be incomplete, since we now lazily deserialize the visible decls of a particular name. Fix the issue by iterating over the un-deserialized visible decls and completing the lookup tables of DeclContexts before writing them out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111698 91177308-0d34-0410-b5e6-96231b3b80d8
