#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): The `UniqFM` approach appears to reduce allocations on `Shape` from 130 MByte to 112 MByte. Sadly this is still a fair bit above the allocations before the constraint tuple change, which was around 95 MByte. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12357#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
