#8279: bad alignment in code gen yields substantial perf issue --------------------------------------------+------------------------------ Reporter: carter | Owner: Type: bug | Status: new Priority: highest | Milestone: Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime performance bug | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: --------------------------------------------+------------------------------ Comment (by carter): @rwbarton, good question! I think we'll just have to figure out some more systematic experiments, and try to get good measurements on a variety of recent cpu micro architectures, to understand this better. Hopefully something we can explore once 7.9 dev gets afoot! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8279#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
