Detailed Description

template<typename FunctionT, typename BranchProbabilityInfoPassT, typename LoopInfoT, typename BlockFrequencyInfoT>
class llvm::LazyBlockFrequencyInfo< FunctionT, BranchProbabilityInfoPassT, LoopInfoT, BlockFrequencyInfoT >

Wraps a BFI to allow lazy computation of the block frequencies.

A pass that only conditionally uses BFI can uncondtionally require the analysis without paying for the overhead if BFI doesn't end up being used.
