示例1: isDereferenceableAndAlignedPointer
bool llvm::isDereferenceableAndAlignedPointer(const Value *V, unsigned Align,
const DataLayout &DL,
const Instruction *CtxI,
const DominatorTree *DT) {
// When dereferenceability information is provided by a dereferenceable
// attribute, we know exactly how many bytes are dereferenceable. If we can
// determine the exact offset to the attributed variable, we can use that
// information here.
Type *VTy = V->getType();
Type *Ty = VTy->getPointerElementType();
// Require ABI alignment for loads without alignment specification
if (Align == 0)
Align = DL.getABITypeAlignment(Ty);
if (!Ty->isSized())
return false;
SmallPtrSet<const Value *, 32> Visited;
return ::isDereferenceableAndAlignedPointer(
V, Align, APInt(DL.getIndexTypeSizeInBits(VTy), DL.getTypeStoreSize(Ty)), DL,
CtxI, DT, Visited);
