2009-11-22If a C++ qualified id is followed by a postfix suffix, it is never the directJohn McCall
operand of an addressof operator, and so we should not treat it as an abstract member-pointer expression and therefore suppress the implicit member access. This is really a well-formedness constraint on expressions: a DeclRefExpr of a FieldDecl or a non-static CXXMethodDecl (or template thereof, or unresolved collection thereof) should not be allowed in an arbitrary location in the AST. Arguably it shouldn't be allowed anywhere and we should have a different expr node type for this. But unfortunately we don't have a good way of enforcing this kind of constraint right now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89578 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-21Added rudimentary C++0x attribute support.Sean Hunt
The following attributes are currently supported in C++0x attribute lists (and in GNU ones as well): - align() - semantics believed to be conformant to n3000, except for redeclarations and what entities it may apply to - final - semantics believed to be conformant to CWG issue 817's proposed wording, except for redeclarations - noreturn - semantics believed to be conformant to n3000, except for redeclarations - carries_dependency - currently ignored (this is an optimization hint) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89543 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-20Implement C++ [basic.lookup.classref]p3, which states how the typeDouglas Gregor

2009-11-12Remove an overly-eager assertion when replacing tokens with anDouglas Gregor
annotation token, because some of the tokens we're annotating might not be in the set of cached tokens (we could have consumed them unconditionally). Also, move the tentative parsing from ParseTemplateTemplateArgument into the one caller that needs it, improving recovery. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86904 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11Fix speculative parsing of dependent template names inDouglas Gregor
nested-name-specifiers so that they don't gobble the template name (or operator-function-id) unless there is also a template-argument-list. For example, given T::template apply we would previously consume both "template" and "apply" as part of parsing the nested-name-specifier, then error when we see that there is no "<" starting a template argument list. Now, we parse such constructs tentatively, and back off if the "<" is not present. This allows us to parse dependent template names as one would use them for, e.g., template template parameters: template<typename T, template<class> class X = T::template apply> struct MetaSomething; Also, test default arguments for template template parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86841 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11Introduce a new representation for template templateDouglas Gregor
parameters. Rather than storing them as either declarations (for the non-dependent case) or expressions (for the dependent case), we now (always) store them as TemplateNames. The primary change here is to add a new kind of TemplateArgument, which stores a TemplateName. However, making that change ripples to every switch on a TemplateArgument's kind, also affecting TemplateArgumentLocInfo/TemplateArgumentLoc, default template arguments for template template parameters, type-checking of template template arguments, etc. This change is light on testing. It should fix several pre-existing problems with template template parameters, such as: - the inability to use dependent template names as template template arguments - template template parameter default arguments cannot be instantiation However, there are enough pieces missing that more implementation is required before we can adequately test template template parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86777 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-10Improve parsing of template arguments to lay the foundation forDouglas Gregor
handling template template parameters properly. This refactoring: - Parses template template arguments as id-expressions, representing the result of the parse as a template name (Action::TemplateTy) rather than as an expression (lame!). - Represents all parsed template arguments via a new parser-specific type, ParsedTemplateArgument, which stores the kind of template argument (type, non-type, template) along with all of the source information about the template argument. This replaces an ad hoc set of 3 vectors (one for a void*, which was either a type or an expression; one for a bit telling whether the first was a type or an expression; and one for a single source location pointing at the template argument). - Moves TemplateIdAnnotation into the new Parse/Template.h. It never belonged in the Basic library anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86708 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-04Change our basic strategy for avoiding deprecation warnings when the decl useJohn McCall
appears in a deprecated context. In the new strategy, we emit the warnings as usual unless we're currently parsing a declaration, where "declaration" is restricted to mean a decl group or a few special cases in Objective C. If we *are* parsing a declaration, we queue up the deprecation warnings until the declaration has been completely parsed, and then emit them only if the decl is not deprecated. We also standardize the bookkeeping for deprecation so as to avoid special cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85998 91177308-0d34-0410-b5e6-96231b3b80d8
