#9630: compile-time performance regression (probably due to Generics) -------------------------------------+------------------------------------- Reporter: hvr | Owner: dfeuer Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Compiler | Version: 7.9 Resolution: | Keywords: deriving- | perf, Generics Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #9583, #10293, | Differential Rev(s): #13059, #10818 | Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): Actually, push that all the way back to 7.4.1, which produces a warning instead of an error for tick exhaustion. I don't have easy access to any earlier versions. So I guess ''part'' of this problem is a lot older than previously realized. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9630#comment:63 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
