#11370: Redundant superclass warnings being included in -Wall destroys the "3 Release Policy" -------------------------------------+------------------------------------- Reporter: ekmett | Owner: bgamari 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: Type of failure: Incorrect | Unknown/Multiple warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: #11369, #11429 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by simonmar): * owner: => bgamari Comment: The plan is: * `-Wall` will include `-Wredundant-constraints` * If at some point we have a compat warning that requires the addition of a redundant constraint to suppress it, then when this warning is enabled at the same time as `-Wredundant-constraints`, we will arrange to not emit a redundant constraint warning for constraints that are required to suppress the compatibility warning. Please let us know if this will cause a problem. @bgamari is going to action the first change. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11370#comment:32 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
