2009-11-03Replace the code that parses member access expressions after "." orDouglas Gregor
"->" with a use of ParseUnqualifiedId. Collapse ActOnMemberReferenceExpr, ActOnDestructorReferenceExpr (both of them), ActOnOverloadedOperatorReferenceExpr, ActOnConversionOperatorReferenceExpr, and ActOnMemberTemplateIdReferenceExpr into a single, new action ActOnMemberAccessExpr that does the same thing more cleanly (and can keep more source-location information). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85930 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-03Introduce a new class, UnqualifiedId, that provides a parsedDouglas Gregor
representation of a C++ unqualified-id, along with a single parsing function (Parser::ParseUnqualifiedId) that will parse all of the various forms of unqualified-id in C++. Replace the representation of the declarator name in Declarator with the new UnqualifiedId class, simplifying declarator-id parsing considerably and providing more source-location information to Sema. In the future, I hope to migrate all of the other unqualified-id-parsing code over to this single representation, then begin to merge actions that are currently only different because we didn't have a unqualified notion of the name in the parser. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85851 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-29Track source information for template arguments and template specializationJohn McCall
types. Preserve it through template instantiation. Preserve it through PCH, although TSTs themselves aren't serializable, so that's pretty much meaningless. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85500 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-29Implement support for semantic checking and template instantiation ofDouglas Gregor
class template partial specializations of member templates. Also, fixes a silly little bug in the marking of "used" template parameters in member templates. Fixes PR5236. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85447 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-27An explicit instantiation definition only instantiations those classDouglas Gregor
members that have a definition. Also, use CheckSpecializationInstantiationRedecl as part of this instantiation to make sure that we diagnose the various kinds of problems that can occur with explicit instantiations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85270 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-27Only set the point of instantiation for an implicit or explicitDouglas Gregor
instantiation once we have committed to performing the instantiation. As part of this, make our makeshift template-instantiation location information suck slightly less. Fixes PR5264. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85209 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-23Eliminate QualifiedDeclRefExpr, which captured the notion of aDouglas Gregor
qualified reference to a declaration that is not a non-static data member or non-static member function, e.g., namespace N { int i; } int j = N::i; Instead, extend DeclRefExpr to optionally store the qualifier. Most clients won't see or care about the difference (since QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the number of top-level expression types that clients need to cope with, brings the implementation of DeclRefExpr into line with MemberExpr, and simplifies and unifies our handling of declaration references. Extended DeclRefExpr to (optionally) store explicitly-specified template arguments. This occurs when naming a declaration via a template-id (which will be stored in a TemplateIdRefExpr) that, following template argument deduction and (possibly) overload resolution, is replaced with a DeclRefExpr that refers to a template specialization but maintains the template arguments as written. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84962 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-22When building and instantiating a template-id reference expression, such asDouglas Gregor
N::f<int> keep track of the full nested-name-specifier. This is mainly QoI and relatively hard to test; will try to come up with a printing-based test once we also retain the explicit template arguments past overload resolution. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84869 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-20Remove default argument for ImpCastExprToType. Add appropriate argument Eli Friedman
to all callers. Switch a few other users of CK_Unknown to proper cast kinds. Note that there are still some situations where we end up with CK_Unknown; they're pretty easy to find with grep. There are still a few missing conversion kinds, specifically pointer/int/float->bool and the various combinations of real/complex float/int->real/complex float/int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84623 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-15Make the remaining explicit-instantiation semantic action useDouglas Gregor

2009-10-15Check the interactions between explicit instantiations and templateDouglas Gregor

2009-10-15Diagnose explicit instantiations of function templates and memberDouglas Gregor
functions/static data members of class template specializations that do not have definitions. This is the latter part of [temp.explicit]p4; the former part still needs more testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84182 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-15More explicit template instantiation. Now we're checking for moreDouglas Gregor

2009-10-14When mapping from an injected-class-name to its correspondingDouglas Gregor
template, make sure to get the template that corresponds to *this* declaration of the class template or specialization, rather than the canonical specialization. Fixes PR5187. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84119 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13Unify our diagnostic printing for errors of the form, "we didn't likeDouglas Gregor
what we found when we looked into <blah>", where <blah> is a DeclContext*. We can now format DeclContext*'s in nice ways, e.g., "namespace N", "the global namespace", "'class Foo'". This is part of PR3990, but we're not quite there yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84028 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13When explicitly specializing a member that is a template, mark theDouglas Gregor
template as a specialization. For example, this occurs with: template<typename T> struct X { template<typename U> struct Inner { /* ... */ }; }; template<> template<typename T> struct X<int>::Inner { T member; }; We need to treat templates that are member specializations as special in two contexts: - When looking for a definition of a member template, we look through the instantiation chain until we hit the primary template *or a member specialization*. This allows us to distinguish between the primary "Inner" definition and the X<int>::Inner definition, above. - When computing all of the levels of template arguments needed to instantiate a member template, don't add template arguments from contexts outside of the instantiation of a member specialization, since the user has already manually substituted those arguments. Fix up the existing test for p18, which was actually wrong (but we didn't diagnose it because of our poor handling of member specializations of templates), and add a new test for member specializations of templates. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83974 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13Improve the internal representation and semantic analysis of friendDouglas Gregor
function templates. This commit ensures that friend function templates are constructed as FunctionTemplateDecls rather than partial FunctionDecls (as they previously were). It then implements template instantiation for friend function templates, injecting the friend function template only when no previous declaration exists at the time of instantiation. Oh, and make sure that explicit specialization declarations are not friends. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83970 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-12When declaring a class template whose name is qualified, make sureDouglas Gregor
that the scope in which it is being declared is complete. Also, when instantiating a member class template's ClassTemplateDecl, be sure to delay type creation so that the resulting type is dependent. Ick. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83923 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-09When declaring a friend class template, we may end up finding anDouglas Gregor

2009-10-08Improve checking for specializations of member classes of classDouglas Gregor
