#13025: Type family reduction irregularity (change from 7.10.3 to 8.0.1) -------------------------------------+------------------------------------- Reporter: acowley | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: TypeFamilies 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 RyanGlScott): acowley, you mentioned that there was a "2x slowdown in the benchmark available in the `vinyl` repository". But I see [https://github.com/VinylRecords/Vinyl/blob/7f436533ba0680434053629df1f844fdb... two benchmarks]. Which benchmark suffered the slowdown? I'd like to verify the change in runtime speed before and after commit 1722fa106e10e63160bb2322e2ccb830fd5b9ab3. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13025#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
