================
Comment at: llvm/include/llvm/IR/Attributes.h:854
 
-  /// Use these to iterate over the valid attribute indices.
-  unsigned index_begin() const { return AttributeList::FunctionIndex; }
-  unsigned index_end() const { return getNumAttrSets() - 1; }
+  struct index_iterator {
+    unsigned NumAttrSets;
----------------
This deserves a comment just for consistency with the rest of these top-level members, even though it's a boring implementation detail of indexes().


================
Comment at: llvm/include/llvm/IR/Attributes.h:863
+      int_wrapper &operator++() {
+        ++i;
+        return *this;
----------------
It's probably worth a comment that this operation is expected to overflow & wrap.
