CGP: Break use-def graph loops in optimizeMemoryInst
Dear Community,
I'm trying to implement optimization described in PR26223 and meet the following bail out condition in CodeGenPrepare::optimizeMemoryInst.
// Break use-def graph loops.
if (!Visited.insert(V).second) {
Consensus = nullptr;
break;
}
So while traversing thorough phi nodes from memory instruction to find addr mode we bail out if we meet some instruction
