#14980: Runtime performance regression with binary operations on vectors -------------------------------------+------------------------------------- Reporter: ttylec | Owner: (none) Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: vector | bitwise operations Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by ttylec): It came to my mind that different stack snapshots could bring different `vector` version along GHC. But that's not the case, both have 0.12.0.1. Please let me know if I can be of any assistance. I tried to debug it more but I have no CS background (I am mathematical physicist) so you need to treat me as a newbie. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14980#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
