Comment (by seraphime):

 I can do it tomorrow.

 Should the message suggest also that -auto-all is deprecated ?

 If it is so, maybe ghc should emit a warning message if -auto-all is used.

 The latest docs don't mention the -auto-all flag [1]. Older docs on the
 other hand describe it in the same terms as the newer -fprof-auto flag.[2]
