xazax.hun added a comment. @leanil : Could you add a test case where the warnings are explicitly disabled in the compilation command and also one where only the aliased warning is explicitly disabled?

That is somewhat intentional I think. Lets imagined you are interested in cppcoreguidelines but not interested in high integrity cpp. It would be great to be able to use Checks: `'cppcoreguidelines*,-hicpp*'` without having to worry about the aliases.

I think the source of the problems is that conceptually there are two distinct reasons to disable a check. One reason when the user is not interested in the results regardless what is the category or name of the check. In this case, all aliases should be disabled. The second is when a category of checks (e.g.: a guideline) is not applicable to the code. In this case aliases should not be disabled. So I think a global option would not solve this issue. A better solution might be a per glob notation. So `-` could mean do not disable aliases and `--` could mean disable aliases as well but that is just an example. All in all, I think this is not related strictly to this issue and I think we should discuss this separately on the mailing list.

I think this is a very good point, this needs to be documented somewhere. https://reviews.llvm.org/D38171 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
