Please note: * Patches should be made relative to ghc HEAD (master). * Your first patch doesn't have a test. See https://ghc.haskell.org/trac/ghc/wiki/Building/RunningTests/Adding * Your second patch isn't needed for ghc HEAD, see #10211. * Patches are preferably sent to [wiki:Phabricator]. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10914#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Will resend the patches to Phabricator. As for the test, I'm not sure how to handle that. I guess adding Data.Hashable to the suite just for this is overkill... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10914#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
