2011-03-01Reinstate the introduction of source-location information forDouglas Gregor
nested-name-speciciers within elaborated type names, e.g., enum clang::NestedNameSpecifier::SpecifierKind Fixes in this iteration include: (1) Compute the type-source range properly for a dependent template specialization type that starts with "template template-id ::", as in a member access expression dep->template f<T>::f() This is a latent bug I triggered with this change (because now we're checking the computed source ranges for dependent template specialization types). But the real problem was... (2) Make sure to set the qualifier range on a dependent template specialization type appropriately. This will go away once we push nested-name-specifier locations into dependent template specialization types, but it was the source of the valgrind errors on the buildbots. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126765 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-01Reinstate r126737, extending the generation of type-source locationDouglas Gregor
information for qualifier type names throughout the parser to address several problems. The commit message from r126737: Push nested-name-specifier source location information into elaborated name types, e.g., "enum clang::NestedNameSpecifier::SpecifierKind". Aside from the normal changes, this also required some tweaks to the parser. Essentially, when we're looking at a type name (via getTypeName()) specifically for the purpose of creating an annotation token, we pass down the flag that asks for full type-source location information to be stored within the returned type. That way, we retain source-location information involving nested-name-specifiers rather than trying to reconstruct that information later, long after it's been lost in the parser. With this change, test/Index/recursive-cxx-member-calls.cpp is showing much improved results again, since that code has lots of nested-name-specifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126748 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-01Push nested-name-specifier source location information intoDouglas Gregor
DependentNameTypeLoc. Teach the recursive AST visitor and libclang how to walk DependentNameTypeLoc nodes. Also, teach libclang about TypedefDecl source ranges, so that we get those. The massive churn in test/Index/recursive-cxx-member-calls.cpp is a good thing: we're annotating a lot more of this test correctly now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126729 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-26Implement delegating constructors partially.Sean Hunt
This successfully performs constructor lookup and verifies that a delegating initializer is the only initializer present. This does not perform loop detection in the initialization, but it also doesn't codegen delegating constructors at all, so this won't cause runtime infinite loops yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126552 91177308-0d34-0410-b5e6-96231b3b80d8

Various infrastructure updates to support NestedNameSpecifierLoc: - AST/PCH (de-)serialization - Recursive AST visitor - libclang traversal (including the first tests of this functionality) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126459 91177308-0d34-0410-b5e6-96231b3b80d8

nested-name-specifiers throughout the parser, and provide a new class (NestedNameSpecifierLoc) that contains a nested-name-specifier along with its type-source information. Right now, this information is completely useless, because we don't actually store the source-location information anywhere in the AST.

2011-02-15Return a declaration to the parser when creating a field in C++ so thatJohn McCall
the parser will complete the declarator with a valid decl and thus trigger delayed diagnostics for it. It certainly looks like we were intentionally returning null here, but I couldn't find any good reason for it, and there wasn't a comment, so farewell to all that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125556 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-14When parsing an out-of-line member function declaration, we must delayJohn McCall
access-control diagnostics which arise from the portion of the declarator following the scope specifier, just in case access is granted by friending the individual method. This can also happen with in-line member function declarations of class templates due to templated-scope friend declarations. We were really playing fast-and-loose before with this sort of thing, and it turned out to work because *most* friend functions are in file scope. Making us delay regardless of context exposed several bugs with how we were manipulating delay. I ended up needing a concept of a context that's independent of the declarations in which it appears, and then I actually had to make some things save contexts correctly, but delay should be much cleaner now. I also encapsulated all the delayed-diagnostics machinery in a single subobject of Sema; this is a pattern we might want to consider rolling out to other components of Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125485 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-03Implement -Woverloaded-virtual.Argyrios Kyrtzidis
The difference with gcc is that it warns if you overload virtual methods only if the method doesn't also override any method. This is to cut down on the number of warnings and make it more useful like reported here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20423. If we want to warn that not all overloads are overriden we can have an additional warning like -Wpartial-override. -Woverloaded-virtual, unlike gcc, is added to -Wmost.

is not defined in the current translation unit. Doing so lead to compile errors such as PR9114.

2011-01-30When building with optimizations, emit vtables where the key is not in the Anders Carlsson
current translation unit as available_externally. This helps devirtualize the second example in PR3100, comment 18: struct S { S() {}; virtual void xyzzy(); }; inline void foo(S *s) { s->xyzzy(); } void bar() { S s; foo(&s); } This involved four major changes: 1. In DefineUsedVTables, always mark virtual member functions as referenced for non-template classes and class template specializations. 2. In CodeGenVTables::ShouldEmitVTableInThisTU return true if optimizations are enabled, even if the key function is not implemented in this translation unit. We don't ever do this for code compiled with -fapple-kext, because we don't ever want to devirtualize virtual member function calls in that case. 3. Give the correct linkage for vtables where the key function is not defined. 4. Update the linkage for RTTI structures when necessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124565 91177308-0d34-0410-b5e6-96231b3b80d8
