#10858: Smaller generated Ord instances -------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: task | 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: #9557 | Differential Revisions: -------------------------------------+------------------------------------- Comment (by nomeata): With some of the ideas in #10858 implemented, the number of terms reported in `-ddump-ds` for `Language.Haskell.Exts.Annotated.Syntax` goes down from 207,936 to 202,252. An improvement, but I was hoping for more. Using the overloaded `(<>)` on `Ordering` incurs a cost; lots of code just to call `<>` with the right instance. It might be worth monomorphizing that to `thenCmp`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10858#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
