Enumerations

enum  llvm::LoopUnrollResult { llvm::LoopUnrollResult::Unmodified, llvm::LoopUnrollResult::PartiallyUnrolled, llvm::LoopUnrollResult::FullyUnrolled }
 Represents the result of a UnrollLoop invocation. More...
 

Functions

const Loopllvm::addClonedBlockToLoopInfo (BasicBlock *OriginalBB, BasicBlock *ClonedBB, LoopInfo *LI, NewLoopsMap &NewLoops)
 Adds ClonedBB to LoopInfo, creates a new loop for ClonedBB if necessary and adds a mapping from the original loop to the new loop to NewLoops. More...
 
LoopUnrollResult llvm::UnrollLoop (Loop *L, unsigned Count, unsigned TripCount, bool Force, bool AllowRuntime, bool AllowExpensiveTripCount, bool PreserveCondBr, bool PreserveOnlyFirst, unsigned TripMultiple, unsigned PeelCount, bool UnrollRemainder, LoopInfo *LI, ScalarEvolution *SE, DominatorTree *DT, AssumptionCache *AC, OptimizationRemarkEmitter *ORE, bool PreserveLCSSA)
 Unroll the given loop by Count. More...
 
bool llvm::UnrollRuntimeLoopRemainder (Loop *L, unsigned Count, bool AllowExpensiveTripCount, bool UseEpilogRemainder, bool UnrollRemainder, LoopInfo *LI, ScalarEvolution *SE, DominatorTree *DT, AssumptionCache *AC, OptimizationRemarkEmitter *ORE, bool PreserveLCSSA)
 Insert code in the prolog/epilog code when unrolling a loop with a run-time trip-count. More...
 
void llvm::computePeelCount (Loop *L, unsigned LoopSize, TargetTransformInfo::UnrollingPreferences &UP, unsigned &TripCount)
 
bool llvm::peelLoop (Loop *L, unsigned PeelCount, LoopInfo *LI, ScalarEvolution *SE, DominatorTree *DT, AssumptionCache *AC, bool PreserveLCSSA)
 Peel off the first PeelCount iterations of loop L. More...
 
MDNodellvm::GetUnrollMetadata (MDNode *LoopID, StringRef Name)
 Given an llvm.loop loop id metadata node, returns the loop hint metadata node with the given name (for example, "llvm.loop.unroll.count"). More...
