#11068: Make Generic/Generic1 methods inlinable -------------------------------------+------------------------------------- Reporter: glguy | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D1447 Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): I remember chatting with some people at ICFP about optimizing Generics code. The problem was that sometimes GHC is able to optimize Generics-based code so that it doesn't use Generics methods anymore. For example, using Generics- based default method of `NFData` sometimes works well, generated code is same as hand-written code. But in some cases it never optimizes enough to eliminate Generics methods. For example, in my tests I was never able to eliminate Generics methods in Generics-based default implementation of `Binary`. I'm wondering if after this patch GHC is able to optimize such instances. @glguy have you tried anything like this? Looks like a good improvement to me, +1. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11068#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
