示例1: addUnknown
void AliasSetTracker::addUnknown(Instruction *Inst) {
if (isa<DbgInfoIntrinsic>(Inst))
return; // Ignore DbgInfo Intrinsics.
if (auto *II = dyn_cast<IntrinsicInst>(Inst)) {
// These intrinsics will show up as affecting memory, but they are just
// markers.
switch (II->getIntrinsicID()) {
default:
break;
// FIXME: Add lifetime/invariant intrinsics (See: PR30807).
case Intrinsic::assume:
case Intrinsic::sideeffect:
return;
}
}
if (!Inst->mayReadOrWriteMemory())
return; // doesn't alias anything
AliasSet *AS = findAliasSetForUnknownInst(Inst);
if (AS) {
AS->addUnknownInst(Inst, AA);
return;
