That's the most frustrating thing about compiler engineering
You fix some feature, some workload, but performance regression appears in other which relied on some bullshit -
unwritten convention, ordering, function name, luck, alignment of the stars, whatever.
You spent 2 weeks fixing a thing and you still have to get back to it because someone is pissed off.
