+/// This file provides the implementation of a basic TargetTransformInfo pass
+/// predicated on the target abstractions present in the target independent
+/// code generator. It uses these (primarily TargetLowering) to model as much
+/// of the TTI query interface as possible. It is included by most targets so
+/// that they can specialize only a small subset of the query space.
