 // Load a narrow Klass from an object.
 // With compact headers, the input address (adr) does not point at the exact
 // header position where the (narrow) class pointer is located, but into the
 // middle of the mark word (see oopDesc::klass_offset_in_bytes()). This node
-// implicitly shifts the loaded value (markWord::klass_shift_at_offset bits) to
-// extract the actual class pointer. C2's type system is agnostic on whether the
-// input address directly points into the class pointer.
