Functions

Valuellvm::stripIntegerCast (Value *V)
 
const SCEVllvm::replaceSymbolicStrideSCEV (PredicatedScalarEvolution &PSE, const ValueToValueMap &PtrToStride, Value *Ptr, Value *OrigPtr=nullptr)
 Return the SCEV corresponding to a pointer with the symbolic stride replaced with constant one, assuming the SCEV predicate associated with PSE is true. More...
 
int64_t llvm::getPtrStride (PredicatedScalarEvolution &PSE, Value *Ptr, const Loop *Lp, const ValueToValueMap &StridesMap=ValueToValueMap(), bool Assume=false, bool ShouldCheckWrap=true)
 If the pointer has a constant stride return it in units of its element size. More...
 
bool llvm::isConsecutiveAccess (Value *A, Value *B, const DataLayout &DL, ScalarEvolution &SE, bool CheckType=true)
 Returns true if the memory operations A and B are consecutive. More...
