> The bug is caused by a mismatch in the way `LoadFlat` and `StoreFlat` > are handled in `ConnectionGraph::find_inst_mem()` and > `MemNode::optimize_simple_memory_chain()`. Once EA has run a first > time, found some value array allocations as non escaping, and removed > their `LoadFlat`/`StoreFlat`, igvn runs and is able to further > transform the memory subgraph which introduces inconsistencies that > are then caught the next time EA runs. > > The fix tries to make sure `ConnectionGraph::find_inst_mem()` and > `MemNode::optimize_simple_memory_chain()` handle `LoadFlat` and > `StoreFlat` similarly. > > --------- > - [x] I confirm that I make this contribution in accordance with the [OpenJDK > Interim AI Policy](https://openjdk.org/legal/ai).
