#13379: Space leak / quadratic behavior when inlining -------------------------------------+------------------------------------- Reporter: jberryman | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 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 dfeuer): All right. I believe I've pinned this down to 45d9a15c4b85a2ed89579106bdafd84accf2cb39 ("Fix a huge space leak in the mighty Simplifier"). * Before: 2.5GB allocated in 4.3s * After: 28.2GB allocated in 19s That's over ten times the allocation, and over 4 times the time! I'll start taking a look at why that may be. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13379#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
