/// 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.
