#11370: Redundant superclass warnings being included in -Wall destroys the "3 Release Policy" -------------------------------------+------------------------------------- Reporter: ekmett | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.0.1 Component: Compiler (Type | Version: 7.10.3 checker) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #11369 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): I’m not sure if the 3-release-policy should get in the way of useful compilier output, and `-Wall` is (rightfully) used by developers to ask the compiler to comment the code as much as sensibly possible. We could refine the policy to promise (or thrive) to deliver `-Wall -Wno- redundant-constraints` cleanliness, and similarly disable other warnings that get in the way of a nice backward-facing compatibility story. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11370#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
