* Initial implementation of parsing, semantic analysis, and templateDouglas Gregor2009-03-271-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | instantiation for C++ typename-specifiers such as typename T::type The parsing of typename-specifiers is relatively easy thanks to annotation tokens. When we see the "typename", we parse the typename-specifier and produce a typename annotation token. There are only a few places where we need to handle this. We currently parse the typename-specifier form that terminates in an identifier, but not the simple-template-id form, e.g., typename T::template apply<U, V> Parsing of nested-name-specifiers has a similar problem, since at this point we don't have any representation of a class template specialization whose template-name is unknown. Semantic analysis is only partially complete, with some support for template instantiation that works for simple examples. llvm-svn: 67875

This approach will greatly simplify the representation of CXXScopeSpec. That'll be next. llvm-svn: 67799

qualified name, e.g., foo::x so that we retain the nested-name-specifier as written in the source code and can reproduce that qualified name when printing the types back (e.g., in diagnostics). This is PR3493, which won't be complete until finished the other tasks mentioned near the end of this commit. The parser's representation of nested-name-specifiers, CXXScopeSpec, is now a bit fatter, because it needs to contain the scopes that precede each '::' and keep track of whether the global scoping operator '::' was at the beginning. For example, we need to keep track of the leading '::', 'foo', and 'bar' in ::foo::bar::x The Action's CXXScopeTy * is no longer a DeclContext *. It's now the opaque version of the new NestedNameSpecifier, which contains a single component of a nested-name-specifier (either a DeclContext * or a Type *, bitmangled). The new sugar type QualifiedNameType composes a sequence of NestedNameSpecifiers with a representation of the type we're actually referring to. At present, we only build QualifiedNameType nodes within Sema::getTypeName. This will be extended to other type-constructing actions (e.g., ActOnClassTemplateId). Also on the way: QualifiedDeclRefExprs will also store a sequence of NestedNameSpecifiers, so that we can print out the property nested-name-specifier. I expect to also use this for handling dependent names like Fibonacci<I - 1>::value. llvm-svn: 67265
