#8326: Place heap checks common in case alternatives before the case -------------------------------------+------------------------------------- Reporter: jstolarek | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: 8317 Related Tickets: #1498 | Differential Revisions: Phab:D343 -------------------------------------+------------------------------------- Comment (by rwbarton): I ran a nofib benchmark with these changes and there was mostly no effect, aside from a few changes in the plus-or-minus 5-10% range that I could not explain. When I find a larger block of free time I'll return to this subject (should be more pleasant now that ghcspeed will benchmark wip branches). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8326#comment:37 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
