#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 simonpj): Do you have allocation numbers for these runs? The mysterious thing is that `NthCo` caching makes things slightly worse. Of course the `NthCo` constructors have an extra field, but I'm still quite surprised that's a visible worsening. So I think it might be worth a little more digging into the worsening in `8ac966971e`, really just to discover if we have accidentally left money on the table. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11735#comment:55 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
