#12640: Class member functions not substituted for MultiParamTypeClasses -------------------------------------+------------------------------------- Reporter: jeremy-list | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by akio): Changing the `INLINE [2]` to `INLINE [1]` allows the rule to fire. I believe the issue is that an `INLINE [2]` is essentially the same as an `INLINE` with no phase specifier, because by default `2` is the first simplifier phase. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12640#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
