Analysis pass providing the [TargetTransformInfo](classllvm%5F1%5F1TargetTransformInfo.html "This pass provides access to the codegen interfaces that are needed for IR-level transformations.").

The core idea of the TargetIRAnalysis is to expose an interface through which LLVM targets can analyze and provide information about the middle end's target-independent IR. This supports use cases such as target-aware cost modeling of IR constructs.

This is a function analysis because much of the cost modeling for targets is done in a subtarget specific way and LLVM supports compiling different functions targeting different subtargets in order to support runtime dispatch according to the observed subtarget.

TargetIRAnalysis::TargetIRAnalysis ( std::function< Result(const Function &)> TTICallback )

Construct an IR analysis pass around a target-provide callback.

The callback will be called with a particular function for which the TTI is needed and must return a TTI object for that function.
