2010-09-01Teach libclang to visit the default arguments of template parameters.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112734 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

2010-09-01Improve libclang indexing support for class template specializationsDouglas Gregor
in a few related ways: - Don't recurse into instantiations of templates. - Recurse into explicit specializations. - Visit the template arguments of an explicit specialization or explicit instantiation. - Include template specialization arguments in the USRs for class template specializations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112720 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
2010-09-01fix rdar://8360877 a really nasty miscompilation in Boost.XpressiveChris Lattner
caused by my ABI work. Passing: struct outer { int x; struct epsilon_matcher {} e; int f; }; as {i32,i32} isn't safe, because the offset of the second element needs to be at 8 when it is interpreted as a memory value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112686 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
2010-08-31Add libclang support for namespace aliases (visitation + USRs) alongDouglas Gregor
with a new cursor kind for a reference to a namespace. There's still some oddities in the source location information for NamespaceAliasDecl that I'll address with a separate commit, so the source locations displayed in the load-namespaces.cpp test will change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112676 91177308-0d34-0410-b5e6-96231b3b80d8

doesn't fit. Instead, special-case the few places where transparent contexts have the desired behavior for inline namespaces. Fixes a redeclaration issue in inline namespaces. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112637 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-31Extend libclang with a new cursor kind that indicates a reference to aDouglas Gregor
template. Such cursors occur, for example, in template specialization types such as vector<int>. Note that we do not handle the super-interesting case where the template name is unresolved, e.g., within a template. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112636 91177308-0d34-0410-b5e6-96231b3b80d8

Also happens to fix PR7804, which I tripped across while testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112604 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-31When instantiating a function type, instantiate the return type beforeDouglas Gregor
instantiating the parameters. In a perfect world, this wouldn't matter, and compilers are free to instantiate in any order they want. However, every other compiler seems to instantiate the return type first, and some code (in this case, Boost.Polygon) depends on this and SFINAE to avoid instantiating something that shouldn't be instantiated. We could fight this battle, and insist that Clang is allowed to do what it does, but it's not beneficial: it's more predictable to instantiate this way, in source order. When we implement late-specified return types, we'll need to instantiate the return type last when it was late-specified, hence the FIXME. We now compile Boost.Polygon properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112561 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-30When template substitution into a template parameter reduces the levelDouglas Gregor
of that parameter, reduce the level by the number of active template argument lists rather than by 1. The number of active template argument lists is only > 1 when we have a class template partial specialization of a member template of a class template that itself is a member template of another class template. ... and Boost.MSM does this.
