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, InsertedPHIs.end()); } With the latest code on trunk compilation of perlbench SPEC CPU 2017 INT benchmark with “-O3 -inline-threshold=1000 an...

Potential infinite loop in MemorySSAUpdater
I understand that changing the starting element to “InsertedPHIs.being() + StartingPHISize” it will be finite but given that InsrtedPHIs is finite. I have a case where one element(same element is appened to InsertedPHIs) is added to InsertedPHIs every time fixupDefs is invoked. I traced the issue why this was happening. template <class RangeType> MemoryAccess *MemorySSAUpdater::tryRemoveTrivialPhi(MemoryPhi *Phi, RangeType &Operands) { // Detect equal or self arguments MemoryAccess *Same = nul...
