struct  llvm::DivRemMapKey
struct  llvm::DenseMapInfo< DivRemMapKey >


 Compute iterated dominance frontiers using a linear time algorithm.


bool llvm::bypassSlowDivision (BasicBlock *BB, const DenseMap< unsigned int, unsigned int > &BypassWidth)
 This optimization identifies DIV instructions in a BB that can be profitably bypassed and carried out with a shorter, faster divide. More...
