That's the conservative fix, yes. You can either: 1. emit global objects with the same section name into a single section unit and then set the mergeable flag and entry size for that unit only if all the objects were mergeable and the same size, or 2. emit global objects with the same section name into different section units based on their mergeability and entry size. If the code isn't already set up to emit multiple section units with a name — which implies that there may also be an existing bug based on having mergeable and non-mergeable symbols with the same section name — then the former is probably much simpler. But if it's already set up to split into two section units, I can't imagine it'd be that difficult to split into more than two.
