Manman Ren c573305bce Debug Info: Rename DITypeRef to DIScopeRef. ... A reference to a scope is more general than a reference to a type since DIType is a subclass of DIScope. A reference to a type can be either an identifier for the type or the DIType itself, while a reference to a scope can be either an identifier for the type (when the scope is indeed a type) or the DIScope itself. A reference to a type and a reference to a scope will be resolved in the same way. The only difference is in the verifier when a field is a reference to a type (i.e. the containing type field of a DICompositeType) or a field is a reference to a scope (i.e. the context field of a DIType). This is to get ready for switching DIType::getContext to return DIScopeRef instead of DIScope. Tighten up isTypeRef and isScopeRef to make sure the identifier is not empty and the MDNode is DIType for TypeRef and DIScope for ScopeRef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190322 91177308-0d34-0410-b5e6-96231b3b80d8		2013-09-09 19:03:51 +00:00
