#9796: Implement amap/coerce rule for `Array` -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: dfeuer Type: task | Status: patch Priority: normal | Milestone: 7.10.1 Component: Core | Version: 7.9 Libraries | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Easy (less than 1 Unknown/Multiple | hour) Type of failure: Runtime | Blocked By: performance bug | Related Tickets: Test Case: | Blocking: | Differential Revisions: Phab:D471 | -------------------------------------+------------------------------------- Changes (by dfeuer): * status: new => patch * differential: => Phab:D471 Comment: Doing this required me to delay inlining `amap` until phase 1, which required me to rewrite it to avoid relying on list fusion. This has a nice side benefit: the compiled code ends up smaller because it avoids a redundant test relating to `enumFromTo` and redundant array freezing code that went with it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9796#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
