[cfe-commits] [Request for approval] Allow clang library applications to get specializations

[Argyrios Kyrtzidis]

Hi Abramo,

How about adding a method to get the specializations in a vector, like the already existing:

  /// \brief Retrieve the partial specializations as an ordered list.
  void getPartialSpecializations(
          llvm::SmallVectorImpl<ClassTemplatePartialSpecializationDecl *> &PS);


Users of the template decls interface would not need to depend on how the specializations are stored.
For example, before I changed getSpecializations() to 'protected', the set contained the latest redeclarations but now the set contains just the canonical decls and we return the latest when the client makes a query about the specializations.
