2009-09-09Allow a declaration of an array to complete a prior, incompleteDouglas Gregor
declaration of that array in C++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81309 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-09Initial stab at implement dependent member references to memberDouglas Gregor
templates, e.g., x.template get<T> We can now parse these, represent them within an UnresolvedMemberExpr expression, then instantiate that expression node in simple cases. This allows us to stumble through parsing LLVM's Casting.h. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81300 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-04Improve the AST representation and semantic analysis for externDouglas Gregor
templates. We now distinguish between an explicit instantiation declaration and an explicit instantiation definition, and know not to instantiate explicit instantiation declarations. Unfortunately, there is some remaining confusion w.r.t. instantiation of out-of-line member function definitions that causes trouble here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81053 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-04Don't generate any code for an explicit call to a trivial destructor. Douglas Gregor
Now that parsing, semantic analysis, and (I think) code generation of pseudo-destructor expressions and explicit destructor calls works, update the example-dynarray.cpp test to destroy the objects it allocates and update the test to actually compile + link. The code seems correct, but the Clang-compiled version dies with a malloc error. Time to debug! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81025 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-04Implement AST, semantics, and CodeGen for C++ pseudo-destructorDouglas Gregor
expressions, e.g., p->~T() when p is a pointer to a scalar type. We don't currently diagnose errors when pseudo-destructor expressions are used in any way other than by forming a call. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81009 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-04Introduce an egregious hack to fix PR4828.Douglas Gregor
The problem this change addresses is that we treat __is_pod and __is_empty as keywords in C++, because they are built-in type traits in GCC >= 4.3. However, GNU libstdc++ 4.2 (and possibly earlier versions) define implementation-detail struct templates named __is_pod and __is_empty. This commit solves the problem by recognizing struct __is_pod and struct __is_empty as special token sequences. When one of these token sequences is encountered, the keyword (__is_pod or __is_empty) is implicitly downgraded to an identifier so that parsing can continue. This is an egregious hack, but it has the virtue of "just working" whether someone is using libstdc++ 4.2 or not, without the need for special flags. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80988 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-03If the alignment of the chosen field in a union is greater than the ↵Anders Carlsson
alignment of the union, we need to use a packed LLVM struct. Fixes <rdar://problem/7184250>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80964 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-03Implement tree transformations for DeclarationNames. Among otherDouglas Gregor
things, this means that we can properly cope with member access expressions such as t->operator T() where T is a template parameter (or other dependent type). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80957 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-03Improve template instantiation for member access expressions thatDouglas Gregor
involve qualified names, e.g., x->Base::f. We now maintain enough information in the AST to compare the results of the name lookup of "Base" in the scope of the postfix-expression (determined at template definition time) and in the type of the object expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80953 91177308-0d34-0410-b5e6-96231b3b80d8

reference/const data members when user has declared the constructor. This necessitated some non-minor refactoring. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80934 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-03Improved handling for dependent, qualified member access expressions, e.g.,Douglas Gregor
t->Base::f where t has a dependent type. We save the nested-name-specifier in the CXXUnresolvedMemberExpr then, during instantiation, substitute into the nested-name-specifier with the (transformed) object type of t, so that we get name lookup into the type of the object expression. Note that we do not yet retain information about name lookup into the lexical scope of the member access expression, so several regression tests are still disabled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80925 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-03This patch does the following.Fariborz Jahanian
1) Issue digsnostics in non-fragile ABI, when an expression evaluates to an interface type (except when it is used to access a non-fragile ivar). 2) Issue unsupported error in fragile ABI when an expression evaluates to an interface type (except when it is used to access a fragile ivar). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80860 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Add a wicked little test-case that illustrates what we have to dealDouglas Gregor
with to properly support member access expressions in templates. This test is XFAIL'd, because we get it completely wrong, but I've made the minimal changes to the representation to at least avoid a crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80856 91177308-0d34-0410-b5e6-96231b3b80d8

must be defined. Fixed pr4853. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80846 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Rewrite of our handling of name lookup in C++ member access expressions, e.g.,Douglas Gregor
x->Base::f We no longer try to "enter" the context of the type that "x" points to. Instead, we drag that object type through the parser and pass it into the Sema routines that need to know how to perform lookup within member access expressions. We now implement most of the crazy name lookup rules in C++ [basic.lookup.classref] for non-templated code, including performing lookup both in the context of the type referred to by the member access and in the scope of the member access itself and then detecting ambiguities when the two lookups collide (p1 and p4; p3 and p7 are still TODO). This change also corrects our handling of name lookup within template arguments of template-ids inside the nested-name-specifier (p6; we used to look into the scope of the object expression for them) and fixes PR4703. I have disabled some tests that involve member access expressions where the object expression has dependent type, because we don't yet have the ability to describe dependent nested-name-specifiers starting with an identifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80843 91177308-0d34-0410-b5e6-96231b3b80d8
