This pass exposes codegen information to IR-level passes.
ARCTTIImpl(ARCTTIImpl &&Arg)
ARCTTIImpl(const ARCTargetMachine *TM, const Function &F)
ARCTTIImpl(const ARCTTIImpl &Arg)
Base class which can be used to help build a TTI implementation.

const DataLayout & getDataLayout() const
This is an optimization pass for GlobalISel generic memory operations.

OutputIt move(R &&Range, OutputIt Out)
Provide wrappers to std::move which take ranges instead of having to pass begin/end explicitly.
Definition: STLExtras.h:1856
Implement std::hash so that hash_code can be used in STL containers.
