示例1: pushIVUsers
/// Add all uses of Def to the current IV's worklist.
static void pushIVUsers(
Instruction *Def, Loop *L,
SmallPtrSet<Instruction*,16> &Simplified,
SmallVectorImpl< std::pair<Instruction*,Instruction*> > &SimpleIVUsers) {
for (User *U : Def->users()) {
Instruction *UI = cast<Instruction>(U);
// Avoid infinite or exponential worklist processing.
// Also ensure unique worklist users.
// If Def is a LoopPhi, it may not be in the Simplified set, so check for
// self edges first.
if (UI == Def)
continue;
// Only change the current Loop, do not change the other parts (e.g. other
// Loops).
if (!L->contains(UI))
continue;
// Do not push the same instruction more than once.
if (!Simplified.insert(UI).second)
continue;
SimpleIVUsers.push_back(std::make_pair(UI, Def));
}
