Semantics: - `-Werror` marks all warnings as fatal, including those that don't have a warning flag, and CPP warnings. - `-Werror=...` enables a warning and marks it as fatal - `-Wwarn=...` marks a warning as non-fatal, but doesn't disable it Test Plan: validate Reviewers: austin, bgamari Reviewed By: bgamari Subscribers: mpickering, svenpanne, RyanGlScott, thomie Differential Revision: https://phabricator.haskell.org/D2706 GHC Trac Issues: #11219 }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11219#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
