2012-12-25Cache visibility of decls.Rafael Espindola
This unifies the linkage and visibility caching. I first implemented this when working on pr13844, but the previous fixes removed the performance advantage of this one. This is still a step in the right direction for making linkage and visibility cheap to use. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171048 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-19PR13470: Ensure that copy-list-initialization isntantiates asRichard Smith
copy-list-initialization (and doesn't add an additional copy step): Fill in the ListInitialization bit when creating a CXXConstructExpr. Use it when instantiating initializers in order to correctly handle instantiation of copy-list-initialization. Teach TreeTransform that function arguments are initializations, and so need this special treatment too. Finally, remove some hacks which were working around SubstInitializer's shortcomings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170489 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-19Change DeclContextLookup(Const)Result to (Mutable)ArrayRef<NamedDecl*>, as ↵David Blaikie
per review discussion in r170365 This does limit these typedefs to being sequences, but no current usage requires them to be contiguous (we could expand this to a more general iterator pair range concept at some point). Also, it'd be nice if SmallVector were constructible directly from an ArrayRef but this is a bit tricky since ArrayRef depends on SmallVectorBaseImpl for the inverse conversion. (& generalizing over all range-like things, while nice, would require some nontrivial SFINAE I haven't thought about yet) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170482 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-08Finish implementing 'selected constructor' rules for triviality in C++11. InRichard Smith
the cases where we can't determine whether special members would be trivial while building the class, we eagerly declare those special members. The impact of this is bounded, since it does not trigger implicit declarations of special members in classes which merely *use* those classes. In order to determine whether we need to apply this rule, we also need to eagerly declare move operations and destructors in cases where they might be deleted. If a move operation were supposed to be deleted, it would instead be suppressed, and we could need overload resolution to determine if we fall back to a trivial copy operation. If a destructor were implicitly deleted, it would cause the move constructor of any derived classes to be suppressed. As discussed on cxx-abi-dev, C++11's selected constructor rules are also retroactively applied as a defect resolution in C++03 mode, in order to identify that class B has a non-trivial copy constructor (since it calls A's constructor template, not A's copy constructor): struct A { template<typename T> A(T &); }; struct B { mutable A a; }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169673 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-08Properly compute triviality for explicitly-defaulted or deleted special members.Richard Smith
Remove pre-standard restriction on explicitly-defaulted copy constructors with 'incorrect' parameter types, and instead just make those special members non-trivial as the standard requires. This required making CXXRecordDecl correctly handle classes which have both a trivial and a non-trivial special member of the same kind. This also fixes PR13217 by reimplementing DiagnoseNontrivial in terms of the new triviality computation technology. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169667 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-16A step towards sorting out handling of triviality of special members in C++11.Richard Smith
Separate out the notions of 'has a trivial special member' and 'has a non-trivial special member', and use them appropriately. These are not opposites of one another (there might be no special member, or in C++11 there might be a trivial one and a non-trivial one). The CXXRecordDecl predicates continue to produce incorrect results, but do so in fewer cases now, and they document the cases where they might be wrong. No functionality changes are intended here (they will come when the predicates start producing the right answers...). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168119 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-14Provide the correct mangling and linkage for certain unnamed nested classes.David Blaikie
This corrects the mangling and linkage of classes (& their member functions) in cases like this: struct foo { struct { void func() { ... } } x; }; we were accidentally giving this nested unnamed struct 'no' linkage where it should've had the linkage of the outer class. The mangling was incorrecty too, mangling as TU-wide unnamed type mangling of $_X rather than class-scoped mangling of UtX_. This also fixes -Wunused-member-function which would incorrectly diagnose 'func' as unused due to it having no linkage & thus appearing to be TU-local when in fact it might be correctly used in another TU. Similar mangling should be applied to function local classes in similar cases but I've deferred that for a subsequent patch.
