#14068: Loopification using join points -------------------------------------+------------------------------------- Reporter: nomeata | Owner: nomeata Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: JoinPoints Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #13966 #14067 | Differential Rev(s): Phab:D3811 #14827 | Wiki Page: | -------------------------------------+------------------------------------- Changes (by kavon): * cc: kavon (added) Comment: While working on my own version of this patch (without knowing about this work yet) I noticed that we may not want to perform the loopification transformation too early, as specialization and other optimizations end up turning a binder marked as `RecursiveTailCalled` into a a full join point, and we end up with better code. Thus, my plan was to implement it as a separate Core pass to figure out at what point(s) during optimization to perform loopification. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14068#comment:42 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
