--- Comment #2 from Ricardo Abreu <ricardolafabreu at gmail dot com> --- Saying "-Wall enables all the warnings that [...]" is inaccurate. Unless you consider a very specific interpretation of "enables". Then it is ambiguous, because there are other valid (and probably more intuitive) interpretations. Preventing that ambiguity from arising in the first place would make for better documentation. The reader should not have to read on specific warnings to find that -Wall, on its own, does not really enable the warnings it claims. The interplay of optimization and correctness analysis feels to me too general to be left to the documentation of individual warning flags. It is something pertaining to a bigger, structural scope.
