#9132: takeWhile&C. still not fusible -------------------------------------+------------------------------------- Reporter: Blaisorblade | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 7.8.2 Resolution: | Keywords: fusion Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: Runtime | Difficulty: Moderate (less performance bug | than a day) Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------- Comment (by simonpj): Joachim is right. Things get fixed when someone decides to fix them! In this case the fix is not hard, but needs a clean `nofib` comparision run to make sure that there are no performance regressions; and preferably a performance test we can add to `testsuite/perf` to check that the fusion really does happen.
