Bug ID: 41083
Summary: Assertion in ScopedHashTable during EarlyCSE
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Scalar Optimizations
Assignee: unassignedb...@nondot.org

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.
