2010-03-04Fix PR6473.Rafael Espindola
Clang's support for weakref is now better than llvm-gcc's :-) We don't introduce a new symbol and we correctly mark undefined references weak only if there is no definition or regular undefined references in the same file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97733 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-03Implement disambiguation of base class members via aDouglas Gregor
nested-name-specifier. For example, this allows member access in diamond-shaped hierarchies like: struct Base { void Foo(); int Member; }; struct D1 : public Base {}; struct D2 : public Base {}; struct Derived : public D1, public D2 { } void Test(Derived d) { d.Member = 17; // error: ambiguous cast from Derived to Base d.D1::Member = 17; // error: okay, modify D1's Base's Member } Fixes PR5820 and <rdar://problem/7535045>. Also, eliminate some redundancy between Sema::PerformObjectMemberConversion() and Sema::PerformObjectArgumentInitialization() -- the latter now calls the former. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97674 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-03Implement name hiding for names found through virtual base subobjectsDouglas Gregor
that are hidden by other derived base subobjects reached along a lookup path that does *not* pass through the hiding subobject (C++ [class.member.lookup]p6). Fixes PR6462. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97640 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-02Suppress implicit member redeclarations arising from explicit instantiationJohn McCall
declarations after the member has been explicitly specialized. We already did this after explicit instantiation definitions; not doing it for declarations meant that subsequent definitions would see a previous member declaration with specialization kind "explicit instantiation decl", which would then happily get overridden. Fixes PR 6458. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97605 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-02[CFG]Ted Kremenek
After discussion with Zhongxing, don't force the initializer of DeclStmts to be block-level expressions. This led to some interesting fallout: [UninitializedValues] Always visit the initializer of DeclStmts (do not assume they are block-level expressions). [BasicStore] With initializers of DeclStmts no longer block-level expressions, this causes self-referencing initializers (e.g. 'int x = x') to no longer cause the initialized variable to be live before the DeclStmt. While this is correct, it caused BasicStore::RemoveDeadBindings() to prune off the values of these variables from the initial store (where they are set to uninitialized). The fix is to back-port some (and only some) of the lazy-binding logic from RegionStore to BasicStore. Now the default values of local variables are determined lazily as opposed to explicitly initialized. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97591 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-02Inspired by seeing "MIPS" go by in the commits, I've gone ahead andJohn McCall
implemented a (codegen) target hook for __builtin_extend_pointer. I'm also making it return a uint64_t instead of an unsigned word; this comports with typical usage (i.e. the one use I know of). I don't know if any of the existing targets requires this hook to be set (other than x86 and x86_64, which I know do not). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97547 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-02Fix an amusing typo that completely the re-introduction of parametersDouglas Gregor
for the purposes of parsing default arguments. In effect, we would re-introduce the parameter with a default argument N times (where N is the number of parameters preceding the parameter with a default argument).
