#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): [[http://home.smart-cactus.org/~ben/ghc/tickets/T12357/Shapes- ticky.diff.html|Here's]] a diff of ticky output from `fulsom`'s `Shapes` module compiled with dd3080fe0263082f65bf2570f49189c277b12e28 and its parent. There's nothing particularly alarming here, as far as I can tell: most of the quantitative differences are in `IfaceType`, `Unique`, `Binary`, and `BinIface`, which all makes good sense given we now need to load more declarations from the `GHC.Classes` interface file. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12357#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
