Detailed Description

template<class BlockT, class FunctionT, class BlockProbInfoT>
class llvm::BlockFrequencyImpl< BlockT, FunctionT, BlockProbInfoT >

BlockFrequencyImpl implements block frequency algorithm for IR and Machine Instructions. Algorithm starts with value ENTRY_FREQ for the entry block and then propagates frequencies using branch weights from (Machine)BranchProbabilityInfo. LoopInfo is not required because algorithm can find "backedges" by itself.
