#10560: -f and -O options interact in non-obvious, order dependent ways -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by gidyn): It's "completely surprising, unnatural and ad hoc" that a warning should be issued when a flag silently undoes the effect of an earlier flag? Additionally, we don't even know if any actual build system will be broken by this. Only if somebody's using a script which breaks if unexpected compiler warnings are encountered, and they're calling GHC with "conflicting" flags in a problematic order. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10560#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
