2010-03-24Walk out of enums when determining effective context.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99391 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-24Correct that last fixit: if the user wroteJohn McCall
template <> friend void foo(int); we need to change it to friend void foo<>(int); or else the user won't get the template specialization they obviously want. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99390 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-24Support friend function specializations.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99389 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-24When a declaration of a function is missing an exception specificationDouglas Gregor
that was present in a prior declaration, emit a warning rather than a hard error (which we did before, and still do with mismatched exception specifications). Moreover, provide a fix-it hint with the throw() clause that should be added, e.g., t.C:10:7: warning: 'operator new' is missing exception specification 'throw(std::bad_alloc)' void *operator new(unsigned long sz) ^ throw(std::bad_alloc) As part of this, disable the warning when we're missing an exception specification on operator new, operator new[], operator delete, or operator delete[] when exceptions are turned off (-fno-exceptions). Fixes PR5957. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99388 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-24Implement a framework for the delay of arbitrary diagnostics withinJohn McCall
templates. So delay access-control diagnostics when (for example) the target of a friend declaration is a specific specialization of a template. I was surprised to find that this was required for an access-controlled selfhost. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99383 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-24When performing name lookup for the allocation or deallocationDouglas Gregor
operators, make sure that the implicitly-declared global new and delete operators are always available. Fixes PR5904. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99382 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-24More vtable work; preparations for moving over to the new vtable layout code ↵Anders Carlsson
(finally). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99381 91177308-0d34-0410-b5e6-96231b3b80d8

scope. Fixes PR6619. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99377 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-24Remove old thunks code.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99374 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-24Make sure to properly track the anonymous namespace that lives insideDouglas Gregor
each namespace, even when the outer namespace has multiple definitions. As part of this, collapsed two pointers worth of storage (original namespace and inner anonymous namespace) into a single pointer with a distinguishing bit, since the two are mutually exclusive, saving a pointer per NamespaceDecl. Fixes PR6620. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99368 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-23Implement computation of the final overriders for each virtualDouglas Gregor
function within a class hierarchy (C++ [class.virtual]p2). We use the final-overrider computation to determine when a particular class is ill-formed because it has multiple final overriders for a given virtual function (e.g., because two virtual functions override the same virtual function in the same virtual base class). Fixes PR5973. We also use the final-overrider computation to determine which virtual member functions are pure when determining whether a class is abstract or diagnosing the improper use of an abstract class. The prior approach to determining whether there were any pure virtual functions in a class didn't cope with virtual base class subobjects properly, and could not easily be fixed to deal with the oddities of subobject hiding. Fixes PR6631. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99351 91177308-0d34-0410-b5e6-96231b3b80d8
