LLVM IR reproducer
PR41081 described an issue where an assertion is hit:
HT.TopLevelMap[ThisEntry->getKey()] == ThisEntry && "Scope imbalance!");
I've attached the LLVM IR from the original ticket. To reproduce:
opt -early-cse locale-reduce.ll -S -o -
I've 'fixed' the original bug by removing this pass from the arm backend
pipeline as I have no experience with this pass.</pre>
