[GHC] #10935: More unused and non-deprecated warning flags
#10935: More unused and non-deprecated warning flags -------------------------------------+------------------------------------- Reporter: osa1 | Owner: Type: task | Status: new Priority: lowest | Milestone: Component: Compiler | Version: 7.10.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: #10752 Differential Rev(s): | -------------------------------------+------------------------------------- For #10752 I was looking at some warning generation code, and I realized that these flags are not doing anything right now, but they're not deprecated: - -fwarn-tabs - -fwarn-monomorphism-restriction - -fwarn-unrecognised-pragmas This one is not even shown in user manual or man page: - Opt_WarnAlternativeLayoutRileTransitional We should probably deprecate and remove them. Another thing is that we should probably remove -fwarn-amp in HEAD. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10935 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Current status: - -fwarn-monomorphism-restriction is unused. - -fwarn-alternative-layout-rule-transitional is used in the lexer but not documented anywhere. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10935#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I don't find «I think the alternative layout rule flags are deliberately not documented at the moment» a very convincing argument. Maybe Ian can clarify? I don't know his trac account. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10935#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
