--- Comment #26 from Vincent Lefèvre <vincent-gcc at vinc17 dot net> --- (In reply to Manuel López-Ibáñez from comment #25) > I don't see any reason for -Wuninitialized to not enable > -Wmaybe-uninitialized. I can see 3 kinds of use: 1. Users who are interested in neither: they just don't use these options (if they want to use -Wall, they need the -Wno- version). 2. Users interested in -Wuninitialized but not in -Wmaybe-uninitialized (to avoid potential many false positives). Because -Wuninitialized enables -Wmaybe-uninitialized, they need 2 options: -Wuninitialized -Wno-maybe-uninitialized. If -Wuninitialized did not enable -Wmaybe-uninitialized, only one option would be needed: -Wuninitialized. 3. Users interested in both. I think that -Wmaybe-uninitialized should enable -Wuninitialized because it makes no sense to have -Wmaybe-uninitialized but not -Wuninitialized. Indeed, if some variable is uninitialized, then it may be uninitialized. So, only one option should be needed in this case: -Wmaybe-uninitialized.
