#11735: Optimize coercionKind -------------------------------------+------------------------------------- Reporter: goldfire | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by tdammers): Status: - Thing 1: Getting rid of non-linearity in coercionKind for the ForallCo case. Done. - Thing 2: Attacking non-linearity in coercionKindRole on NthCo's. I think this part is also more or less done, but I haven't seen anything on phab yet. - Thing 3: Fixing performance issues with `simplCast` / `SimplCore`. Moved to #14737, I believe @goldfire is still working on this. - Thing 4: Investigating `CoreTidy`. Moved to #14738, however it seems that the problem no longer manifests on GHC HEAD. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11735#comment:70 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
