#12357: Increasing maximum constraint tuple size significantly blows up compiler allocations -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): One thing to point out here is that a significant amount of cost from this patch is due to the construction of the superclass dictionary selectors (e.g. `OccName.mkSuperDictSelOcc`), since we now have to construct a few thousand more selectors than we did previously. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12357#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
