#8173: GHC uses nub -------------------------------------------------+------------------------- Reporter: nh2 | Owner: Type: bug | leroux Priority: low | Status: new Component: Compiler | Milestone: Resolution: | Version: 7.6.3 Operating System: Unknown/Multiple | Keywords: Type of failure: Compile-time performance bug | Architecture: Test Case: | Unknown/Multiple Blocking: | Difficulty: | Unknown | Blocked By: | Related Tickets: -------------------------------------------------+------------------------- Comment (by leroux): I've attached a patch to include compile time alloc info on #8409. I'll keep digging in but so far it doesn't look like allocation is affected significantly either. {{{ Compile Allocations ------------------------------------------------------------------------------- Program head-0 head-1 ordNub-0 ordNub-1 ordNub-cases-0 ordNub-cases-1 ------------------------------------------------------------------------------- -1 s.d. ----- -0.0% -0.0% -0.0% -0.0% -0.0% +1 s.d. ----- +0.0% +0.0% +0.0% +0.0% +0.0% Average ----- +0.0% +0.0% +0.0% +0.0% +0.0% }}} 0% across the board, apparently. Any other suggestions anyone? Perhaps I'll try to replace the few `nub`'s I left laying around in the compiler. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8173#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
