Howard Hinnant aab2305454 Seciton 24.2.2 of the C++ standard, [iterator.iterators], Table 106 ... requires that the return type of *r for all iterators r be reference, where reference is defined in [iterator.requirements.general]/p11 as iterator_traits<X>::reference, and X is the type of r. But in CFG.h, the dereference operator of PredIterator and SuccIterator return pointer, not reference. Furthermore the nested type reference is value_type&, which is not the type returned from operator*(). This patch simply makes the iterator::reference type value_type*, which is what the operator*() returns, and then re-lables the return type as reference. From a functionality point of view, the only difference is that the nested reference type is now value_type* instead of value_type&. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178240 91177308-0d34-0410-b5e6-96231b3b80d8		2013-03-28 15:47:50 +00:00
