Hal Finkel	a2347baaec	Mark C++ reference parameters as dereferenceable ... Because references must be initialized using some evaluated expression, they must point to something, and a callee can assume the reference parameter is dereferenceable. Taking advantage of a new attribute just added to LLVM, mark them as such. Because dereferenceability in addrspace(0) implies nonnull in the backend, we don't need both attributes. However, we need to know the size of the object to use the dereferenceable attribute, so for incomplete types we still emit only nonnull. llvm-svn: 213386	2014-07-18 15:52:10 +00:00

Francois Pichet	6422579411	Add support for explicit constructor calls in Microsoft mode. ... For example: class A{ public: A& operator=(const A& that) { if (this != &that) { this->A::~A(); this->A::A(that); // <=== explicit constructor call. } return *this; } }; More work will be needed to support an explicit call to a template constructor. llvm-svn: 123735	2011-01-18 05:04:39 +00:00
