[flang-commits] [flang] [flang] Use module file hashes for more checking and disambiguation (PR #80354)

I like the strategy.

Plus, as I understand the logic, the new "$!need" is optional (the check will just not be performed if it is not here), so this will not break existing .mod from people's build (they will just pick up the change the next time they rebuild the module with an updated flang).
