I'm not sure, because many of the new warnings are added with the intention of adding them to -Wall sooner or later, so the positive list would need to grow, too. Also, the list of warnings included in -Wall is much longer than the list of warnings excluded. An option is to provide both lists and remark that if a warning is on neither list, it must be a new one and please file a Trac ticket. Then we are at least not stating a falsehood.
I try to build a list status of options here https://gist.github.com/voanhduy1512/7769e04b925069170212400b57f5d4a3. Right now there is more options which excluded in `-Wall` than included. Maybe it will be change in future but i think it's easier to add positive list. For example i add a option to `-Wall` but forgot to update the doc, it's easy to update the doc to correct state just by looking at the code. As for current state, i need to get all options, minus all default options, minus all `-W`, `-Wall`, to get the real list that are not in `-Wall`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14229#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
