I still feel a bit reluctant since the potential false positives would at least be left to the user to decide how to handle, while the false negatives from this option would just be lost without indication. I don't see much value left in this check if one decides to use the option, anyone who would use this option might be better of just doing this check manually instead, then again it's optional of course. If there wouldn't be much of a loss in performance I guess there isn't any significant harm in adding the option though, I'll give it a shot. > In D74463#1878290 <https://reviews.llvm.org/D74463#1878290>, @vingeldal wrote: > >> Also consider that even in the cases where the order of the parameters >> doesn't matter, like an averaging function, there is also the possibility to >> re-design to avoid this warning, by passing the parameters as some kind of >> collection of parameters. > > > Forcing a developer to jump through hoops is not a great idea imo I didn't suggest forcing anything though.
