#10491: Regression, simplifier explosion with Accelerate, cannot compile, increasing tick factor is not a workaround -------------------------------------+------------------------------------- Reporter: robertce | Owner: Type: bug | Status: new Priority: highest | Milestone: 7.10.2 Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by George): Replying to [comment:14 bgamari]: I was able to compile it with -fsimpl-tick-factor=150, not sure if memory use was reasonable, cpu usage was close to 100%. As I wrote above: when I do ghc -O2 -fsimpl-tick-factor=150 Slice.hs it quickly uses over 11G of memory. I'm not sure what the peak memory use is or how long it took to compile as I let it run overnight (I have 12G of RAM on my Mac). The resulting binary of the 321 line source file is 51 MB -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10491#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
