all -fwarn flags are missing from flagsForCompletion
That is intended behavior I think. Those flags are deprecated, ad replaced by equivalent `-W` flags. `-fwarn-`, `-fno-warn` and `-W` probably show up in the output of `--show- options` because of this code from `compiler/main/DynFlags.hs`: {{{ ++ [ (NotDeprecated, unrecognisedWarning "W") , (NotDeprecated, unrecognisedWarning "fwarn-") , (NotDeprecated, unrecognisedWarning "fno-warn-") ] }}} For a newcomer. Adding a test is optional. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12099#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
