Potential infinite loop in MemorySSAUpdater
Hi,
Can some one explain the intended behaviour of following loop in void MemorySSAUpdater::insertDef(MemoryDef *MD, bool RenameUses) function.
while (!FixupList.empty()) {
unsigned StartingPHISize = InsertedPHIs.size();
fixupDefs(FixupList);
FixupList.clear();
// Put any new phis on the fixup list, and process them
FixupList.append(InsertedPHIs.end() - StartingPHISize,
